DIRECTOR’S CORNER - 2014

The year of 2014 saw continuing activities on both Oneida

Lake and the Great Lakes, with several new initiatives for

CBFS. Oneida Lake continues to be a fascinating natural

laboratory that is undergoing ecological change through

increases in some exotic species (round goby, white perch, and

quagga mussels), through increases in several native species

(black bass, chain pickerel, gizzard shad) and through global

climate change and changes in the watershed. The value of the

long term data series for understanding the effects of these

changes on this lake and elsewhere is only increasing each

year. This data series was started by John Forney in 1958, and

John still finds interesting information in each new year of data.

It is such a pleasure to have John continuing his work with us at CBFS. We are getting close to finishing a book

on Oneida Lake which will analyze data up to 2010 and serve as a milestone for understanding future changes in

the lake. We also work with a long-term data set on the Great Lakes, and another milestone completed in 2014

is a special issue on the state of Lake Ontario based on the intensive field studies in 2008. This issue came out

in Aquatic Ecosystem Health and Management early in 2015.

New initiatives in 2014 are the NSF funded project with Ian Hewson exploring the ecological importance of

viruses for crustaceans in both marine and freshwater environments (two new graduate students Kalia Bistolas

and Elliot Jackson); a project on angler economics with Rich Read, Bruce Lauber, Greg Poe, Rich Stedman and

Nancy Connelly that is investigating the economic costs of invasive species to the Great Lakes Region; and a

project on comparing the coupling between mussels and hydrodynamics in three lakes (Cayuga, Onondaga and

Oneida). We also continue our connections with EPA and Buffalo State to assess ecosystem changes across the

Great Lakes including planning for the intensive field year in Michigan in 2015 and the collaborations with the

Lake Ontario science and management agencies. Our research portfolio also includes projects in several other

smaller lakes (Onondaga, Silver, Canadarago, Cayuga) and international collaborations, primarily through

GLEON. Oneida Lake and the Field Station became official site members of GLEON (Global Lakes Ecological

Observatory Network) in 2014. Workshops at the station in 2014 included Lake Ontario planning, angler

economics workshop, aquatic plant identification, and teacher training for the Education Initiative. Indeed an

active year at CBFS.

Several Shackeltonians left the station in 2014. Some went to graduate school including Sarah Burnet to Idaho,

Brian O’Malley to Vermont and Elliot Jackson to Cornell. Others went to jobs – Milan Riha returned to Czech

Republic as a scientist at the Czech Academy, Wendy Patterson went to Buffalo State to work with our

colleagues Drs. Karatayev and Burlakova, Kyle Nauseef returned to Cortland, and Collin Farrell went to

Massachusetts DNR in Fisheries. We miss them at Shack. New Shackeltonians include the Great Lakes

technicians Joe Connolly and Lyndsie Collis, Nasseer Idrisi from the American University in Iraq who spent the

summer with us and is coming back in 2015, and Xuifeng Zhang from Jinan University, Guangzhou, China who

is with us for a year as a visiting professor. Robin DeBruyne successfully defended her PhD thesis –

congratulations Dr. DeBruyne – and Jim Watkins was promoted to Research Associate.

It is a pleasure to be the director with such great colleagues at the Field Station.

2014 CBFS INTERNS

Interns at CBFS during the summer of 2014 had the

opportunity to work on varied research projects addressing

current ecological concerns. Funding for our intern

program comes from the Great Lakes and warmwater

grants, the Cornell Lab of Ornithology, and a generous gift

from the Forney family to support one intern each year

working on Oneida Lake. In addition, 2014 saw the first

Duke Conservation Scholars based at CBFS, sponsored by

the Doris Duke Foundation and selected based on a

demonstrated interest in environmental issues and a

commitment to fostering cultural diversity in the field of

conservation. The interns presented their findings in August as part of the CBFS Summer Seminar

program at Shackelton Point and in December of 2014 at the Department of Natural Resources

Undergraduate Research Symposium. A special thanks to the intern advisors without whom this program

would not exist – in 2014 Randy Jackson, Tom Brooking, Amy Hetherington, Annie Scofield, Toby

2014 CBFS PROGRAM HIGHLIGHTS

Oneida Lake and other Inland Lakes

A major research program at CBFS is the Oneida Lake projects that involve two CBFS senior scientists

with Jackson concentrating on fish and fisheries and Rudstam concentrating on lower trophic levels. Paul

Curtis and Rebecca Schneider also had active projects on Oneida Lake in 2014. The program involves the

research staff Brooking, VanDeValk, Holeck, and Hotaling, several graduate students (DeBruyne,

Hetherington, Craig) and summer interns. In addition, we work with Onondaga Lake food web analyses,

effects of alewife in Canadarago Lake and Silver Lake

(PA), and assessing the impact of mussel nutrient

excretion on phosphorus levels in Cayuga Lake

(Watkins with UFI and Buffalo State scientists).

Oneida Lake is a site member of GLEON and part of

several research projects comparing data from lakes

across the world. One new initiative in 2014 is a hatch

project designed to understand the coupling between

hydrodynamics and mussel filtering rates by

incorporating mussels in a General Lakes Model

developed by GLEON collaborators (Hipsey and

Bruce, University of Western Australia).

Ongoing project: Long-term studies of Oneida Lake

Randy Jackson, Tom Brooking, Tony VanDeValk, Lars Rudstam, Kristen Holeck, Christopher Hotaling,

Lauren Mott, John Forney (Funded by New York State Department of Environmental Conservation)

Our studies of the fisheries and limnology of Oneida Lake were initiated in the mid-1950s as an

assessment of the status of the lake’s important walleye and yellow perch fisheries. The program has

enjoyed continuous funding from the New York State Department of Environmental Conservation and for

almost 40 years has included annual monitoring of multiple trophic levels and physical conditions,

representing a true ecosystem approach to understanding the dynamics of the lake’s fish community and

fisheries. While maintaining the continuous data set started by John Forney, we have increased the scope

of our studies, which now include intensive sampling of the lake’s nearshore fish community. Oneida

Lake is the State’s second most heavily fished lake, and data collected by Field Station staff provide

timely information to DEC managers to ensure sustainable fishing opportunities, particularly for walleye,

yellow perch and smallmouth bass. The data series has also allowed important insights into the response

of lake ecosystems to perturbations such as exotic species and climate change. We have already

documented fundamental shifts in fish community composition resulting from increases in water clarity

associated with zebra mussels, and are currently assessing the impacts of displacement of zebra mussels

by quagga mussels. The double-crested cormorant had profound impacts on walleye and yellow perch,

and our studies of these impacts have informed cormorant management throughout their range. Analyses

of the response of walleye and yellow perch to cormorant management are shedding light on the relative

importance of that management and concurrent restrictions of walleye harvest, Warming water

temperatures may be contributing to increased production of largemouth and smallmouth bass, gizzard

shad and other species near the northern extent of their range, while burbot, at the southern edge of their

range, may be in decline. Sampling in 2014 revealed that the round goby has finally established in the

lake, although currently at low densities. We will have an excellent opportunity to assess the impacts of

this new invasive on the lake’s fish and fisheries. Ongoing studies on Oneida Lake include detailed

studies of walleye and yellow perch from larval to adult life stages, assessment of offshore and inshore

fish community composition and monitoring of nutrients, primary and secondary production, as well as

annual creel surveys. Walleye anglers enjoyed an excellent early season, but catch rates fell off as

emerald shiner and gizzard shad came on in late summer. Nonetheless, anglers harvested nearly 60,000

walleye in 2014. We have initiated spring electrofishing surveys designed to assess centrarchid

populations, particularly bass, which will complement the fall fyke net surveys we implemented several

years ago to assess the nearshore fish community. As Oneida Lake has changed, so too has the fish

community and the fishery, and our studies continue to expand in our efforts to understand the dynamics

of this economically important resource.

Ongoing project: Common terns on Oneida Lake

Paul Curtis, Liz Craig, Ryan Rodriguez (Funded by Laboratory of Ornithology and Doris Duke Scholars

Program)

The long-term studies on the colonial waterbirds on Oneida Lake, initiated in the 1970s, continued during

2014. Investigators Paul Curtis and Liz Craig worked with intern Ryan Rodriguez to monitor the nesting

activity of Common Terns on Little Island. Breeding success for Common Terns at Oneida Lake was very

poor this field season due to a combination of several

factors, including potential gull predation, severe storms

with high winds during peak nesting, and cormorants

spending time on Little Island. This year 350 Common

Tern nests were initiated, and a total of 126 tern chicks

were banded (this is down from 500 to 600+ chicks

banded during the past few summers). This year in

addition to our traditional monitoring, banding, and

habitat improvement activities, we continued a study of

tern migration to determine where birds nesting on

Oneida Lake are migrating and overwintering. We

recaptured 4 of 10 terns marked with geolocators in 2013

(small tracking devices that record bird location using

daylight sensors), and affixed an additional 10

geolocators to banded adult terns. During summer 2015,

we will retrieve the migration information from these

devices when the birds return to nest on Little Island.

Ongoing Project: Silver Lake biomanipulation experiment

Lars Rudstam, Paul Simonin, Chris Hotaling, (Funded by the Rose Conservancy and the Actus

Foundation)

The research on alewife in a small lake in northern Pennsylvania investigates the interactions between

alewife, zooplankton, and stocked brown and rainbow trout. With the help of citizen scientist Russ Cole,

we collect data on the zooplankton and water clarity in Silver Lake and study the abundance, growth and

condition of the alewife population. Rainbow and brown trout have been stocked into the lake

intermittently since 2006 in an effort to control alewife and allow the lake to return to the higher water

clarity observed in the 1990s. Unfortunately, alewives have continued to defy the predators and are still

abundant in the lake. High alewife abundance is associated with small zooplankton and low water clarity

in the lake, and this trend continued in 2014. Although we have not yet observed the intended outcome of

the biomanipulation experiment, we do get valuable information on a dense slow growing alewife

population in a mesotrophic lake.

Ongoing project: Food web changes in Onondaga Lake

Lars Rudstam, Chris Hotaling, Margaret Murphy, Steve Effler,

Dave Matthews, Chris Gandino, Janaki Suryadevara (Funded by

Onondaga County, NY)

Onondaga Lake was known as one of the most polluted lakes in

the US in the 1980s. However, improvements to the sewage

treatment plant and work by Honeywell on the benthic subsystem

have led to clear improvements in the water quality of the lake.

But water clarity is also affected by zooplankton grazing and

mussel filtering. Zooplankton in turn is affected by fish

predation, particularly alewife. We are investigating the

interaction between these two grazers and how food web effects

interact with improvement in the treatment plant and water

quality in the lake. We are also involved with overseeing the

sampling program through the Onondaga Lake Technical

Advisory Board (Mills and Rudstam). This work has led to increased collaborations with the Upstate

Freshwater Institute in Syracuse led by Steve Effler. Ongoing project: Canadarago Lake alewife – walleye interactions

Tom Brooking, Randy Jackson, Lars Rudstam, Dave Green (Funded by New York State DEC)

In 2014, we continued collecting fisheries and limnology data from Canadarago Lake. Data has been

collected from the lake over the last two decades and we are now wrapping up our involvement as this is

the last year of our sampling on Canadarago Lake. We are assembling the historic data to investigate

causes and consequences of the invasive species that entered this lake, in particular alewife and zebra

mussels. Alewives are increasing in this lake, causing concerns for future reproduction of walleye. More

details will be available in next year’s report.

Completion report: 2013 Benthic survey of Cayuga Lake

Jim Watkins, Lars Rudstam, Wendy Paterson, Kyle Nauseef, Jonathan Hunn, Alexander Karatayev,

Lyuba Burlakova (Buffalo State) (Funded by Cornell Department of Energy and Sustainability)

This project was part of Cornell University’s monitoring efforts associated with its lake source cooling

system. This utility cools campus buildings through heat transfer with deep Cayuga Lake water. Several

collaborating Cornell researchers and scientists from Upstate Freshwater Institute (UFI) joined to study

phosphorus cycling in the lake. An important question addressed was why phosphorus levels of the

hypolimnion in Cayuga Lake have risen over the past decade. Our hypothesis is that the expansion of

exotic dreissenid mussels (particularly quagga mussels) has contributed to this phosphorus increase. In

2014 CBFS scientists presented the results of their 2013 benthic monitoring project within a final report

and at several venues including UFI’s Onondaga Lake Forum at SUNY-ESF Syracuse, NYS DEC offices

in Albany, NY, and the technical committee of Lake Source Cooling. Our estimates of excretion by

quagga mussel biomass at depths in Cayuga Lake explain a large portion of the observed phosphorus

increase in the hypolimnion. In 2015 we will continue to work with hydrodynamic modelers at UFI to

quantify this process and its implications.

Completion report: Re-engineering of Oneida Lake, interactions between climate change and

invasive species

Amy Hetherington, Lars Rudstam, Randy Jackson, Rebecca Schneider, Kristen Holeck, Chris Hotaling,

Alicia Zhao (Funded by Cornell Hatch grant and the Shackelton Endowment)

As the climate is changing, invasive species are also impacting the structure and function of inland

waters. In this study we used hydrodynamic models for Oneida Lake to predict the degree of temperature

increase in the lake by the end of the century (4 C) and the increase in stratification (up to 2 months,

Hetherington et al., 2015, Ecological Modeling). This has potential to increase phosphorus release into the

water column and therefore blue-green blooms in Oneida Lake. We coupled the hydrodynamic model

with mussel filtration rates measured in experiments to better understand the coupling between this

invasive species and climate change. Filtration rates of zebra mussels consistently exceeded those of

quagga mussels at all temperatures. Based on the results of this study, zebra mussels would be expected to

dominate across current and predicted future temperature regimes; however, other factors need to be

considered due to the ubiquity of quagga mussels in numerous lakes worldwide. This work is continuing

with the new initiative described below.

Lakes are a major attraction and economic driver for

Upstate NY. The three lakes we propose to study are

particularly important. Oneida Lake is the second

most utilized lake for fishing in NYS (after Lake Ontario) and attracts national fishing tournaments.

Onondaga Lake is improving from being one of the most polluted lakes in North America to being an

asset to the City of Syracuse due to the implementation of substantial improvements to Onondaga

County’s Metro sewage treatment plant. Cayuga Lake is at the center of the Finger Lakes district with

local economies related to lake and wine region tourism. Cayuga Lake water is also used for a lake source

cooling project with implications for decreasing carbon emissions. Changes to these lakes could affect the

economy of the whole region.

Two of the most important threats to the structure and function of these lakes are climate change and

invasive species, in particular two species of dreissenid mussels – the zebra mussel (Dreissena

polymorpha) and the quagga mussel (Dreissena rostriformis bugensis). The two dreissenid mussels are

considered ecosystem engineers because they increase water clarity and transform the bottom structure of

lakes. Quagga mussels invaded the three study lakes around 2005 and are replacing zebra mussels as the

dominant species in all three systems. Ecosystem changes due to quagga mussels are likely larger than

those from zebra mussels because quagga mussels can colonize a larger portion of the bottom substrate.

However, both species of mussels are restricted to the bottom and therefore depend on sedimentation and

water circulation to deliver food particles to that habitat. Water circulation is in turn affected by the

morphometry of lakes and by temperature increases associated with climate change. These two drivers of

ecological change (invasives and climate change) will interact, but the degree of interactions and the

magnitude of ecological change to the lakes will depend on the morphometry of the lake. Therefore,

ecological forecasting requires consideration of both lake physics and lake biology.

We propose to develop a framework for forecasting the simultaneous effects of climate change and

quagga mussels using input data from three New York lakes with contrasting physical characteristics.

Oneida Lake is large and relatively shallow making the lake polymictic. In this lake, mussels have access

to much of the water column most of the year. Onondaga Lake is smaller and undergoes thermal

stratification in the summer. As summer progresses, the water below the thermocline becomes depleted

of oxygen and goes anoxic by mid-July. This restricts mussels to shallow bottoms close to the shoreline

that contains adequate oxygen concentrations throughout the summer. Cayuga Lake is deep (140m) and

also thermally stratifies in the summer but does not go anoxic. Quagga mussels therefore occur at all

depth in Cayuga Lake. We chose these three lakes because of the existing data on both mussel abundance

and lake limnology from all three lakes. These data sets will allow us to test the importance of lake

morphometry on the interaction between invasive mussels and climate change and therefore generalize

across many of the lakes in New York State. Our results will also have relevance beyond New York State

as we work with the Global Lakes Environmental Observatory Network (GLEON), an international

grassroots organization of researchers, educators, and community groups invested in the future of

freshwaters, in developing these models.

Global Lakes Ecological Observatory Network (GLEON) Projects

As a site member of GLEON and through the involvement of Amy Hetherington in the GLEON

organization, Oneida Lake is used in several projects that benefit from comparative approaches to

limnology and lake – watershed interactions. Amy Hetherington and Lars Rudstam work with

collaborators across the globe on the following projects:

General Lake Model with Louise Bruce and Matthew Hipsey (University of Western Australia), Gideon

Gal (Yigal Allon Kinneret Limnological Laboratory, Israel), Jordan Read (USGS, Wisconsin, United

States), and other GLEON collaborators

The General Lake Model Multi-Lake Comparison

Project (GLM-MLCP) is a community driven

initiative where researchers from the Global Lake

Ecological Observatory Network (GLEON) and

Aquatic Ecosystem Modeling Network (AEMON)

collectively simulate lakes using a common approach

to setup and assessment. More than 20 lakes,

including Oneida Lake, have been simulated, ranging

in latitude from 56oN to 38

oS, in elevation from -210

to +560 m above sea level, from trophic status of

oligotrophic to eutrophic, depth from 12 to 253 m,

volume from 6.9x105 to 4.8x10

10 m

3, mixing regimes

from polymictic to meromictic and from a range of

climates including warm lakes to lakes with seasonal

ice cover. The expected outcome of the study is an

improved knowledge of the strength and limitations of the GLM, a standardized calibration and globally

relevant parameter set, and an improved understanding of characteristic drivers and forcing patterns of

stratification in lakes. The analysis highlights the ability of the model to capture varying stratification

based on lake morphometry and prevailing climate. A globally validated model allows better assessment

of global change impacts on lake and reservoirs.

Global Lake Temperature Collaboration, examining global lake temperature trends from in situ

and remote sensing data with John Lenters (LimnoTech), Catherine O’Reilly (Illinois State University),

Jordan Read (USGS), Sapna Sharma (York University), Derek Gray (University of California), and other

GLEON collaborators

Recent studies have revealed significant warming of lakes throughout the world, and the observed rate of

lake warming is, in many cases, more rapid than that of the ambient air temperature. The scientific

community is just beginning to understand the global extent, regional patterns, physical mechanisms, and

ecological consequences of lake warming. Although many in situ lake temperature records are available,

only a few encompass long time periods. The Global Lake Temperature Collaboration is an international

effort to synthesize global records of lake temperature from in situ and satellite-based measurements.

Surface water temperature data are analyzed from over 120 lake, including Oneida Lake, distributed

across 40 countries. The focus is primarily on mean summer water temperatures for the 25 year period of

1985-2009. Linear regression analysis reveals that 65% of the lakes are experiencing significant summer

warming (p<0.1), with another 30% warming at a rate that is not statistically significant. Only 5% of the

lakes show cooling trends (none of which are significant). Multi-authored papers have been accepted in

Nature Data and submitted to Science.

Modeling long-term trends in ice seasons of geographically distributed lakes in a changing climate

with Nihar Samal (CUNY Institute for Sustainable Cities), Don Pierson (Uppsala University, Sweden),

Bruce Hargreaves (Lehigh University, Pennsylvania), Craig Williamson (Miami University, Ohio), and

other GLEON collaborators

Long-term trends and variability in lake ice dynamics are related to changes in climate conditions.

Changes in the duration and timing of ice cover are well documented effects of climate change that are

expected to continue into the future. Simulations of ice conditions and duration are essential to

understanding the mechanics through which ice cover potentially mediates the effects of climate on lake

thermal structure and mixing and influences phytoplankton succession and trophic status of a lake. In this

study, a simple, one-dimensional model, Simple Ice Model (SIM), from Australia’s Commonwealth

Scientific and Industrial Research Organization, will be applied to several lakes worldwide, including

Oneida Lake, to predict the onset, loss, and duration of ice cover in a changing climate. The expected

results of this study will lead to understanding the effects of climate change on lake ice phenology and

implications for the physical, chemical, and biological structure of lakes.

Ongoing Project: Storm Blitz, impacts of storms on phytoplankton composition with Bas Ibelings

(University of Geneva, Switzerland), Orlane Anneville (INRA, France), Jason Stockwell and Emily

Nodine (University of Vermont) and other GLEON collaborators.

Storm-Blitz is related to the effects of physical disturbances and water column stability on plankton

communities. Ongoing GLEON projects have revealed phytoplankton traits associated with stable water

column conditions which strengthen our understanding of the role of thermal stratification in steering

phytoplankton composition and succession at the annual scale. However, succession can be set back by

alterations of the ambient environment due to the intervention of external disturbances such as floods,

storms or episodes of increased wind mixing. Consequently, changes in phytoplankton composition are

expected to follow the occurrence of extreme meteorological events. Long-term datasets of phytoplankton

communities and environmental conditions for several lakes worldwide, including Oneida Lake, will be

used to test whether water column disturbance driven by storms affects phytoplankton assembly, in term

of diversity, species, and morpho-functional traits. The expected results should facilitate understanding of

the sensitivity of aquatic ecosystems to extreme weather events.

The CBFS Great Lakes Program

In 2014, CBFS continued to be at the forefront of Great Lakes research. We

entered our second year of our collaboration with Buffalo State University in

monitoring all five Great Lakes with the US EPA Great Lakes National Program

Office (GLNPO) based in Chicago. We continue to collaborate with regional, state

and federal agencies and academics in the analysis of the Cooperative Science and

Monitoring Initiative’s (CSMI) intensive sampling year of 2013 for Lake Ontario.

In addition, NY DEC, USGS and USFWS collaborate with us on a lower trophic

level biomonitoring program in Lake Ontario, a program that has been continuous

since 1995. We also continued our efforts on Lake Champlain with Vermont Fish

and Wildlife and University of Vermont scientists and a project aimed at restoring

the native cisco population in Lake Ontario. New initiatives include a project on

the importance of amphipod viruses to ecological interactions in both the Great

Lakes and the Pacific (funded by NSF) and a project on angler economics funded

by the GLFC.

GLNPO monitors all five Great Lakes each April and August aboard their 180 ft. vessel, the Lake

Guardian. The ship has state of the art sampling equipment including a Seabird CTD (equipped with

sensors for temperature, dissolved oxygen, light, particles and chlorophyll a) and onboard laboratory

facilities. They also have traditional nets and dredges for plankton and benthic sampling. The Guardian

provides the capability to continuously sample throughout the Great Lakes for up to a month and sample

any depth within the Great Lakes. In 2014, we continued to collect and analyze samples for chl a,

zooplankton, mysid shrimp, and benthos (Buffalo State). We also explored advanced technology (i.e.

hydroacoustics and Triaxus array) in comparison with our traditional measurements. These tools provide

high resolution measurements on horizontal and vertical spatial scales. Zooplankton and mysid samples

from these surveys are brought back to CBFS for analysis by our technician team in our renovated

laboratory.

Dove (Environment Canada), Tom Stewart, Tim Johnson, Brent Metcalf (OMNR), Tom Nalepa (Univ

Michigan) (Funded by EPA CESU grant).

CBFS participated in this large multiagency effort on the lake in 2013 with federal, state and provincial

agencies (EPA, USGS, NYSDEC in the US; OMNR, DFO and EC in Canada). During 2014, several

CBFS scientists presented preliminary results from our research at the annual meeting of the International

Association of Great Lakes Research (IAGLR) in Hamilton, Ontario. CBFS hosted workshops for

collaborators to inventory data sets and gaps, prioritize research questions, and identify leaders and

collaboration teams for individual projects. CBFS secured funding from the Great Lake Observing

System (GLOS) to hire a data manager in 2015 to assist in this synthesis. Our monitoring activities are

supplemented by several research interests. Two graduate students in the Cornell DNR continue to be

supported by the GLNPO grant. Annie Scofield’s thesis project involves the deep chlorophyll layer and

implications of a vertical redistribution of primary production in the Great Lakes. Toby Holda’s thesis

project includes tracking the vertical and horizontal distribution of mysid shrimp. Our collaboration with

US EPA provides the students with data throughout the Great Lakes that will allow for critical inter-lake

comparisons in these times of multiple stressors.

Ongoing project: Dynamics of the deep chlorophyll layer

Annie Scofield (Funded by EPA and Great Lakes Fisheries

Commission)

Deep chlorophyll layers (DCL’s) are important features during

thermal stratification in large oligotrophic lakes. The presence of a

DCL has been observed in all five of the North American Great

Lakes, but its ecological significance is not well understood. Annie is

working with GLNPO researchers to better understand the ecological

importance of the DCL across the Great Lakes, with a particular

focus on Lake Ontario in 2013. Greater water clarity in Lake Ontario

has led to increased formation of the DCL and a vertical re-

structuring of the food web. The shift in primary production from

warm surface waters to cool deeper waters may have important

implications for the bioenergetics of organisms using this food

source, including zooplankton, mysids and fish. Annie is exploring

several technologies (i.e. Triaxus array, Fluoroprobe, and autonomous gliders) to track the formation and

dissipation of this feature.

On-going project: Lake Ontario Biomonitoring Program

Kristen Holeck, Chris Hotaling, Lars Rudstam, Jana Lantry (NYSDEC), Brian Weidel (USGS), Betsy

Trometer (USFWS) and additional collaborators around Lake Ontario. (Funded by New York DEC,

USGS, USFWS)

Ecosystem-based management is an approach to managing environmental issues that considers how the

ecosystem functions as a whole rather than focusing on single species or issues in isolation. In Lake

Ontario, managers have used an ecosystem-based approach to managing the productivity and availability

of alewife and stocked salmonids since the end of the 1980s. In support of this approach, and with the

realization that populations of top predators could not be managed effectively without understanding the

production potential of Lake Ontario’s lower trophic levels, the New York State DEC initiated research in

1995 called the Lake Ontario Biomonitoring Program (BMP) to evaluate the condition of lower trophic

levels in offshore, nearshore, and embayment areas of the lake. Lower trophic level components

(nutrients, phytoplankton, and zooplankton) are indicators of ecosystem health and determine the lake’s

ability to support prey fish upon which both wild and stocked salmonids depend. Changes since 1995

have been dramatic with almost an order of magnitude decrease in herbivorous zooplankton, a decrease in

summer chlorophyll (an indicator of phytoplankton abundance), and increases in non-native predatory

cladocerans (Bythotrephes longimanus and Cercopagis pengoi). Alewife have shifted to feeding more on

mysids, possibly in response to lower zooplankton abundance and increased water clarity. Knowledge of

these changes informs management decisions regarding stocking of salmonids in Lake Ontario. The

BMP is a collaborative project that, in 2014, included the NYSDEC Cape Vincent Fisheries Research

Station and regional NYSDEC staff at Watertown, Cortland, and Avon; the U.S. Fish & Wildlife Service

Lower Great Lakes Fish & Wildlife Conservation Office; the U.S. Geological Survey–Lake Ontario

Biological Station; and Cornell University.

Ongoing project: Mysis ecology in the Great

Lakes

Toby Holda (Funded by EPA)

Mysids are an important native species in all the

Great Lakes. Understanding mysid ecology is an

essential component of understanding these

systems as the species is both a major predator on

zooplankton and a major prey for alewife, smelt

and native coregonids. Even so, they are not well

studied and there are multiple questions about

mysid ecology that remain unanswered. Some of

these include: 1) the acoustic relationships used to

calculate densities; 2) trophic interactions and

food-web dynamics; 3) influence of vertical and horizontal distribution patterns on these interactions; 4)

the influence of the deep chlorophyll layer and other environmental factors on these distributions and

food-web dynamics. An early goal is to compile the GLNPO time series for mysid abundance for the

Great Lakes.

Ongoing project: Cisco restoration in Lake Ontario

Ellen George and Lars Rudstam (Cornell), Mathew Levine and Darran Crabtree (TNC), Mike Connerton

(NYDEC), Jim Johnson (USGS-Tunison), Zy Beisinger (USFWS). Funded by The Nature Conservancy

Cisco are an important prey fish for many Great Lakes predators, including lake trout. Their numbers

have declined drastically in the last century due to the impacts of invasive species such as sea lamprey

and alewife, overfishing, and habitat degradation. Chaumont Bay, New York contains one of the last

remaining spawning populations of cisco in Lake Ontario. This new project is a collaboration between

Cornell University, The Nature Conservancy of New York, the New York DEC, and the USGS, and is

funded by a grant from The Nature Conservancy. The goals of the project are 1) to assess the status of the

existing spawning population, 2) to locate the spawning location within Chaumont Bay, and 3) to identify

any limitations to recruitment that may be affecting the population. In

November and December of 2013 we attempted to identify the

spawning site using radio telemetry. Further investigation into the

spawning site using an egg pumping device was completed in February

and March of 2014. Eggs were found on Johnson, Middle and Herrick

Shoals using the pumping method, and genetic analysis confirmed all

eggs as cisco. Eggs were also collected during November and

December of 2014 using egg mats, which will allow us to give a density

estimate of cisco egg deposition at various sites in Chaumont Bay.

Larval and zooplankton collections were made in April and May of

2014, and the larvae will be genetically identified and used for larval

distribution and diet analysis in 2015. Future work on this project

includes habitat mapping using side scan sonar with US Fish &

Wildlife, investigation into the possible predation on larvae by invasive

alewife, and modeling of other potential spawning sites in Chaumont

Bay.

Ongoing project: Smelt-alewife interactions in Lake Champlain

Paul Simonin, Patrick Sullivan, Lars Rudstam, Alison Hrycik (Cornell), Donna Parrish (Univ Vermont),

Bernie Pientka (Vermont Fish&Wildlife), Allison Hrycik, Tim Mihuc (SUNY-Plattsburgh), (Funding from

Champlain Sea Grant)

Alewife invaded Lake Champlain in the early 2000s and are displacing native rainbow smelt in some

parts of the lake. We are continuing our analysis of this process through spatially-explicit models of stage

structured population dynamics of the two interacting species. Differing amounts of spatial overlap

between adults and young-of-year, and associated differences in cannibalism and predation on larvae, are

the likely mechanisms explaining the increase in alewife in this system. However, a large year-class of

rainbow smelt was observed in the main lake section of Lake Champlain in August 2014, suggesting

alewife are not displacing rainbow smelt entirely. An understanding of this continuing rainbow smelt-

alewife interaction will help explain the dominance of alewife over smelt in other Great Lakes. In

addition, a study on the importance of mysids in Lake Champlain was accepted for publication in 2014.

New Project: Biogeochemical and ecological impacts of amphipod circoviruses in benthic habitats.

Ian Hewson, Lars Rudstam, Elliot Jackson and Kalia Bistolas (Funding from the National Science

Foundation)

Circoviruses (ssDNA, circular genome) are emerging as a common viral genotype associated with aquatic

crustacea. These poorly understood viruses are well known to infect vertebrate hosts (including pigs and

birds), however they have only recently been detected as constituents of viral communities in seawater,

lakes and soils. Targeted studies of viruses associated with herbivorous zooplankton in marine and

freshwater habitats identified a cluster of circoviral sequences that are distinct from those infecting

vertebrate hosts, and which are widespread in aquatic plankton and sediments. As part of prior support,

we have identified the high prevalence, active replication, deleterious impacts on arthropod cells, and

have evidence for the ecological role of circoviruses in copepods, Daphnia and amphipods. It is clear

from preliminary work that circoviruses likely impact the community ecology of aquatic crustacea,

however the magnitude of their roles in crustacean ecology and subsequent impacts on aquatic

ecosystems are not yet resolved. The overarching goal of this proposal is to examine how viral infection

alters biogeochemical cycling in aquatic habitats by studying circoviral impacts on an important group of

benthic detritivores and herbivores, the amphipods. The proposal will address two major questions in

biological oceanography: 1) Do viruses of epifaunal metazoa alter benthic biogeochemical cycling?; and

2) Do viruses reduce the nutritional quality of benthic invertebrates consumed by higher trophic levels?

This proposal is not geared towards discovery or descriptive aspects of circoviral biology and ecology.

Rather, it embraces experimental approaches to understand circoviral ecology within host populations and

how those interactions may influence ecosystem function.

New Project: Biological and social impacts of aquatic invasive species in the Great Lakes:

development of scenarios through expert judgment and assessment of impacts on recreational

angling.

Richard Ready, Pennsylvania State University, Bruce Lauber, Lars Rudstam, Richard Stedman, Nancy

Connelly, and Gregory Poe, Cornell University ( Funded by the Great Lakes Fisheries Commission)

The magnitude of future impacts of aquatic invasive species (AIS) on Great Lakes fish communities and

the subsequent impacts on recreational fisheries are potentially large, but unknown and the subject of

intense public debate. With little scientific basis, stakeholders are making projections of the impacts of

AIS on sport fishing that range from negligible to catastrophic. Projections of the consequences of AIS in

the Great Lakes should be based on the best ecological science available on the potential impacts of AIS

on fish communities and on the best social science available on how anglers will react and be impacted by

those changes. This project will address the following research questions: 1) What are the potential

impacts of AIS on recreationally-important Great Lakes fish species? 2) What are the potential impacts of

AIS on sport fishing participation and value? Objectives are 1) Develop an economic model of Great

Lakes recreational angling that projects how sport fishing participation and value would change as a result

of changes in sport fish abundance. 2) Develop a set of plausible, science-based ecological scenarios

about the possible effects of AIS on recreationally important fish populations in the Great Lakes. 3) Use

the angler behavior model to project the impact the AIS scenarios would have on angler behavior and on

the net economic value of recreational fishing in the Great Lakes.

CBFS Outreach, Extension and Education Programs

On-going project: Lake Ontario and Oneida Lake Education Initiative

JoAnne Getchonis, David White and Lars Rudstam (funded by the Shackelton Endowment, Cornell Hatch

grant, New York Sea Grant)

2014 was another active year for the Education Initiative. We continue to work with educators in the

Oneida Lake and Lake Ontario watersheds. Events included a hands-on demonstration for students from

the Central Square High School Science Club at the South Shore boat launch on Oneida Lake. Students

pulled a near-shore seine and identified net contents. Discussions focused on native and invasive species.

Also CBFS again partnered with NY Sea Grant’s Helen Domske and Dave White to host a three day

educator training program on Lakes Ontario and Oneida in July of 2014. Fall of 2014 saw an invasive

species workshop titled “Call to Action: Community Engagement”. There were representatives of many

local and state groups, both governmental and NGO’s, as well as lake associations. In addition, the

Chittenango High School Science department spent a curriculum day at CBFS, working to add the local

Oneida Lake watershed into their classroom activities. This was followed up by an in-school Oneida

Lake program.

FACILITIES AND MAINTENANCE

Grounds and building maintenance continues to be a priority for Shackelton Point. Windows were

upgraded in the Taylor House/Point residence in compliance with current NYS Fire Safety regulations.

The dormitory is moving closer to completion with help from Cornell University Facilities. Substantial

interior work was completed in 2014. Cabinets and appliances were installed in the first floor kitchen, and

bathing and restroom facilities were installed. Bringing water to the dorm is scheduled for April 2015.

We are optimistic that the dorm will be available for use in late spring 2015.

The on-site sewer project was scheduled to begin in October of 2014 but due to contractor delays, work

began in 2015. We received a grant from NYS, as well as assistance from the Ithaca campus Facilities

group to move forward in connecting to the Town of Sullivan sewer system. We anticipate completion

of that project by May 2015.

Initial conceptual designs are in place for the renovation of the chemistry lab on the first floor in the main

office building. CBFS staff worked with Cornell University Facilities to draft a room layout that is

workable and efficient. This project will include a newly partitioned room with updated fume hood,

cabinets and an area that can be cordoned off for chlorophyll work.
