- 摘要：
- , open populations now incorporate population growth models and simultaneously test for covariate effects on abundance and detection probability. However, estimati
Data from: The conservation status and population decline of the African penguin deconstructed in space and time
- 负责人：
- DOI：
- doi:10.5061/dryad.vx0k6djp7
- 摘要：
- Understanding changes in abundance is crucial for conservation, but population growth rates often vary over space and time. We use 40 yea
