- 摘要:
- Analyses of historical samples can provide invaluable information on changes to the genetic composition of natural populations resulting from
Data from: Herbivory differentially affects plant fitness in three populations of the perennial herb Lythrum salicaria along a latitudinal gradient

- doi:10.5061/dryad.mk966
- 摘要:
- plant population dynamics and evolution. Latitudinal variation in intensity of herbivory is common, but the extent to which it translates into corresponding variati
Data from: Contrasting dynamics of a mutator allele in asexual populations of differing size
- 负责人:
- DOI:
- doi:10.5061/dryad.v0v58gd5
- 摘要:
- _b (for subpopulation of size N and beneficial mutation rate U_b) exceeds that of the wild-type subpopulation. Here, we examine the effect of total population size
Data from: Effective number of breeders, effective population size and their relationship with census size in an iteroparous species
- 负责人:
- DOI:
- doi:10.5061/dryad.nh448
- 摘要:
- te to population dynamics and fluctuations in population size are important for the design of robust conservation strategies in small populations with overlapping generati
Data from: Predicting heterosis and inbreeding depression from population size and density to inform management efforts
- 负责人:
- DOI:
- doi:10.5061/dryad.ncjsxksrf
- 摘要:
- c drift, inbreeding and response to selection, and thus the distribution of the genetic load across populations. 2. We examined if census population size and density
Data from: Population size, habitat fragmentation, and the nature of adaptive variation in a stream fish
- 负责人:
- DOI:
- doi:10.5061/dryad.6t794
- 摘要:
- rge populations. Yet fragmentation is known to increase variability within and among habitats as population size decreases. Such variability might instead favour
Data from: Exploring the causes of small effective population sizes in cyst nematodes using artificial Globodera pallida populations
- 负责人:
- DOI:

- 摘要:
- . The balance between selection and genetic drift depends on the effective population size (Ne), rather than the real numbers of individuals in the population
Data from: Back from the brink: potential for genetic rescue in a critically endangered tree

- 摘要:
- Rare plant species are vulnerable to genetic erosion and inbreeding associated with small population size and isolation due to increasing
Data from: Rapid evolution leads to differential population dynamics and top-down control in resurrected Daphnia populations

- 摘要:
- change may subsequently impact ecological processes such as population dynamics, community composition and ecosystem functioning. To study such eco
