Hotspots, Population Turnover and Long-Term Data: Ecological Insights From a Short-Lived Frog.

ABSTRACT: Population turnover (local extinction and recolonization) is a fundamentally important ecological process but one that is not often (or easily) studied. Even more poorly known are the local and landscape factors that influence population turnover. We leverage a long-term monitoring dataset on a short-lived frog (Blanchard's cricket frog, Acris blanchardi) to provide empirical estimates of local extinction and colonization frequency in an occupancy modeling framework that explicitly addresses detection probability. We surveyed 102 aquatic habitats in northwestern Ohio (USA) using 1491 listening surveys from 2004-2008 and 2017-2022. Estimated colonization and extinction rates were very similar over the entire period 2004-2022 (0.1099 (SE = 0.0149) and 0.1014 (SE = 0.0301), respectivel
