Gigantism and the age of extinction.
17 February 2022
Determining how biodiversity will respond to the current climatic and environmental crisis is a key conservation science goal. However ...
... such forecasts are typically based entirely on recent records of species (last ~50 years). This is problematic, given that these recent records are strongly affected by human interactions and we do not know whether current distributions reflect the full suite of environmental parameters a species can inhabit. As such, our concepts of baselines of biodiversity, including extinction rate and size selectivity (e.g. whether large-bodied species are most at-risk), are severely distorted by the narrow temporal lens through which they are viewed.
