Data from: Partitioning the sources of demographic variation reveals density-dependent nest predation in an island bird population
- 负责人：
- DOI：

- 摘要：
- ve failure, while also evaluating how biotic and abiotic factors jointly shape demography. We examined the effects of population density and precipitation on fecundity
Data from: Hidden founder effects: small-scale spatial genetic structure in recently established populations of the grassland specialist pla

- 摘要：
- The long-term establishment success of founder plant populations has been commonly assessed based on the measures of population genetic diversi
Data from: Exploring the causes of small effective population sizes in cyst nematodes using artificial Globodera pallida populations

- 摘要：
- zes. The consequences of a low Ne, resulting in a strong intensity of genetic drift, could be important for their control because G. pallida populations will have a low
Data from: Does source population size affect performance in new environments?
- 负责人：
- DOI：
- doi:10.5061/dryad.81k4v
- 摘要：
- population size on performance was inconsistent across life-history stages (LHS) and environments. When transplanted to the same set of new environment
Data from: Daphnia invest in sexual reproduction when its relative costs are reduced

- 摘要：
- with population density and with decreasing asexual clutch sizes. The frequency of sexually reproducing females additionally increased as population growth rates decreased

- 摘要：
- of five species of voles to investigate whether RTS responds to natural fluctuations in population density, i.e. variation in sperm competition risk. We sh
Data from: Patterns of pollen flow in a dense population of the insect-pollinated canopy tree species Castanopsis sieboldii
- 负责人：
- DOI：
- doi:10.5061/dryad.s17s3d5r
- 摘要：
- Insect pollinations of tree species with high-density populations have rarely been studied. Since the density of adults can affect effecti
Data from: Unexpected high genetic diversity in small populations suggests maintenance by associative overdominance

- 摘要：
- adult census population sizes (10, 50 or 500) using pooled RAD sequencing. In small populations, variation was lost at a substantially lower rate tha

- 摘要：
- in the Soutpansberg Mountains, and drew on a previous estimate of leopard population density for the region from 2008. In 24 sampling periods, we esti
