Monitoring and Biodiversity Indices

„Monitoring is commonly defined as the process of gathering

information about state variables at different points in

time for the purpose of drawing inferences about changes

in state (Yoccoz et al. 2001), whereas an indicator is defined

as a metric that represents that state. Biodiversity

indicators can be straightforwardmetrics, such as relative

abundance of species, or they can be composite metrics

that combine data from a number of different monitoring

programs (Collen et al. 2009).“

Species concepts

morphological species concept:A species is a community, or a number of related communities, whose distinctive morphological

characters are ... sufficiently definite to entitle it, or them, to a specific name.” biological species concept

AA species is a group of interbreeding natural populations unable to successfully mate or reproduce with other such groups, and which occupies a specific niche in nature.”

  phylogenetic species concept “A species is the smallest aggregation of populations (sexual) or lineages (asexual) diagnosable

by a unique combination of character states in comparable individuals”

We intuitively recognize a species as a group of closely similar organisms, such as humans, horses or carrots. The scientific definition has varied historically, but one that is often cited

today is 'a group of morphologically similar organisms of common ancestry that under natural conditions are potentially capable of interbreeding.'

Calculating the Index

The Living Planet Database (LPD) holds time-series data for over 10,000 populations of more than 2000 vertebrate species from around the world.The global LPI is calculated using over 7000 of these population time-series which are gathered from a variety of sources such as journals, online databases and government reports.

The IUCN Red List currently comprises conservation

assessments for nearly 50,000 species. Around 60% of these

are vertebrates.

The Sampled Red List Index (SRLI)

The Sampled Red List Index is an adaptation of the IUCN Red List Index (RLI), which is based

on the IUCN Red List of Threatened Species and is an indicator of the relative rate at

which the conservation status of certain species groups change

over time.

How is the SRLI calculated?

Red List Index scoresIn a nutshell, the SRLI uses weight scores based on the Red List status of each of the sample species.

These scores range from 0 (Least Concern) to Extinct/Extinct in the Wild (5).

Summing these scores across all species and relating them to the worst-case scenario - where all species are extinct - gives us an indication of how biodiversity is doing.

Repeating the assessments over time will then allow us to see whether the extinction risk of biodiversity is overall increasing, decreasing or staying the same.

Red List Calculation For example, this can be seen in the picture at the top of the page which shows the RLI for all birds as calculated by Birdlife Internation in collaboration with the IUCN.

Global Amphibian Assessment

The GAA assessed threat status and distribution for each of the

5,743 amphibian species known to science.

More than 520 scientists from over 60 countries contributed to the three-year study.

Results provide a baseline for global amphibian conservation, and will be used to design strategies to save the world’s rapidly declining amphibian populations

The Panamanian golden frog is one of roughly 110 species of harlequin frog (Atelopus), many of which are dying out. Although this species still

survives, its numbers have fallen significantly.
