‘Cool’ sampling sites more likely to show false trends in biodiversity change

Data collected by citizen science initiatives, museums and national parks is an important basis for research on biodiversity change. However, scientists from the German Centre for Integrative Biodiversity Research (iDiv), Leipzig University (UL) and Martin Luther University Halle-Wittenberg (MLU) found that sampling sites are oftentimes not representative, which may lead to false conclusions about how biodiversity changes. Their research, published in Conservation Biology, calls for more objective site selection and better training for citizen scientists to prevent a site-selection bias.
