What happens to a lake ecosystem during a cyanobacterial bloom?
• Toxins, scums, odors all well documented• But, what about lake biogeochemical cycles
(C, N, P)? Phytoplankton, zooplankton dynamics?
• Cyanobacterial blooms significantly impact many ecosystem variables
Expanding my analysis to the GLEON network
• Survey indicates that ~55% of GLEON lakes consistently exhibit blooms every year
• Range of trophic status and cyanobacterial species represented
Soliciting historical & limnological data from GLEON (and non-GLEON) lakes
• I am collecting:1. Historical weekly datasets2. Weekly plankton samples
• If you can take a weekly plankton sample at your GLEON lake, I will count and ID the phytos for you.
• I will acknowledge you and your site on any publications that result from this project.
Lake/data requirements• Lake must experience at least one bloom/summer. • Plankton sample must be collected weekly
throughout bloom season using a standardized sampling protocol.
• After bloom season ends, we will identify when bloom events occurred, and you will mail me the samples.
• I will count the phytos and send you the data.
Why this is a ‘cool thing’
• Cyanobacterial blooms are increasing every year in geographical range and frequency; there is much we do not know
• One of the first attempts to utilize the GLEON network to conduct large-scale, collaborative biology; perhaps a model for future GLEON research?
