Data from: Evolution of drift robustness in small populations
- 负责人：

- DOI：
- doi:10.5061/dryad.nr780
- 摘要：
- Most mutations are deleterious and cause a reduction in population fitness known as the mutational load. In small populations, weakened selection agains
Data from: Effects of population size and isolation on heterosis, mean fitness, and inbreeding depression in a perennial plant
- 负责人：
- DOI：
- doi:10.5061/dryad.s7gm5
- 摘要：
- In small isolated populations, genetic drift is expected to increase chance fixation of partly recessive, mildly deleterious mutations, reducing mea
Data from: Different evolutionary paths to complexity for small and large populations of digital organisms
- 负责人：

- DOI：
- doi:10.5061/dryad.3h5kv
- 摘要：
- for the evolution of complexity in biological populations. Here, we used digital experimental evolution to test whether large or small asexual populations tend
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
Data from: Inter-population variation in mating system and late-stage inbreeding depression in Magnolia stellata

- DOI：
- doi:10.5061/dryad.1292
- 摘要：
- r relationships with population size and the degree of population isolation were not detected. However, in one population, which was very small and located

- 摘要：
- How population size influences quantitative genetic variation and differentiation among natural, fragmented populations remains unresolved. Smal
Data from: Does source population size affect performance in new environments?
- 负责人：
- DOI：
- doi:10.5061/dryad.81k4v
- 摘要：
- small populations within native environments, but only at later life stages. Population size was not associated with habitat quality. Several factors might expla
Data from: Are heritability and selection related to population size in nature? Meta-analysis and conservation implications
- 负责人：
- DOI：
- doi:10.5061/dryad.rd5rn
- 摘要：
- vely, our results (i) indirectly suggest that genetic drift neither overwhelms selection more in small than in large natural populations, nor weakens
Data from: Spatiotemporal relationship between adult census size and genetic population size across a wide population size gradient

- DOI：
- doi:10.5061/dryad.f9f75
- 摘要：
- difference between variability in Nb and/or Nb/N among small and large populations; however, small populations had more varying temporal variability in Nb
Data from: The benefits of interpopulation hybridization diminish with increasing divergence of small populations
- 负责人：
- DOI：
- doi:10.5061/dryad.4298p
- 摘要：
- Interpopulation hybridization can increase the viability of small populations suffering from inbreeding and genetic drift, but it can also result
