- genetic drift effective population size density dependence environmental stochasticity demographic stochasticity fluctuating populations mating systems sex ratio fluctuations
- DOI：
- doi:10.5061/dryad.7m2r4
- 摘要：
- Density dependence in vital rates is a key feature affecting temporal fluctuations of natural populations. This has important implications
Data from: Direct effects of a non-native invader erode native plant fitness in the forest understory

- 摘要：
- liaria’s effects on vital rates differed in magnitude and sign across the native’s lifecycle, highlighting the importance of detailed demographic analyses. Global
Data from: Demographic drivers of a refugee species: large-scale experiments guide strategies for reintroductions of hirola
- 负责人：
- DOI：
- doi:10.5061/dryad.480tf
- 摘要：
- Effective reintroduction strategies require accurate estimates of vital rates and the factors that influence them. We estimated vital rates of hirola
