Data from: Disentangling ecologically equivalent from neutral species: the mechanisms of population regulation matter
- 负责人：
- McPeek, Mark
- DOI：
- doi:10.5061/dryad.t4k343g
- 摘要：
- community drift dynamics analogous to neutral alleles undergoing genetic drift. While entire communities of species are not ecologically equivalent, recent
Data from: Modern spandrels: the roles of genetic drift, gene flow and natural selection in the formation of parallel clines
- 负责人：
- DOI：
- doi:10.5061/dryad.6nv2t4p
- 摘要：
- a drift. Gradients in the strength of drift across a landscape resulted in phenotypic clines with lower frequencies of HCN in strongly drifting populations
Data from: The relative roles of cultural drift and acoustic adaptation in shaping syllable repertoires of island bird populations change with time
- 负责人：
- DOI：
- doi:10.5061/dryad.n8c22
- 摘要：
- In birds, song divergence often precedes and facilitates divergence of other traits. We assessed the relative roles of cultural drift, innovation

- DOI：
- doi:10.5061/dryad.t4b8gthzr
- 摘要：
- hout the Holocene in the whole northern Adriatic Sea. The size shift coincided with compositional change of the benthic community, with the median per-assemblage
Data from: Frequency dependence and ecological drift shape coexistence of species with similar niches
- 负责人：
- DOI：
- doi:10.5061/dryad.vj260
- 摘要：
- The coexistence of ecologically similar species might be counteracted by ecological drift and demographic stochasticity, both of which erode local
Data from: Regime shifts in marine communities: a complex systems perspective on food web dynamics
- 负责人：
- DOI：
- doi:10.5061/dryad.p9f07
- 摘要：
- Species composition and habitats are changing at unprecedented rates in the world’s oceans, potentially causing entire food webs to shift
Data from: Selection, drift and introgression shape MHC polymorphism in lizards
- 负责人：
- DOI：
- doi:10.5061/dryad.d3kk74r
- 摘要：
- scenarios where other evolutionary processes (e.g. genetic drift and introgression) may also be acting. Here, we focus on two closely related green lizard
Data from: Adaptive divergence despite strong genetic drift: genomic analysis of the evolutionary mechanisms causing
- 负责人：
- DOI：
- doi:10.5061/dryad.2kn1v
- 摘要：
- The evolutionary mechanisms generating the tremendous biodiversity of islands have long fascinated evolutionary biologists. Genetic drift
Data from: Local adaptation and ecological differentiation under selection, migration and drift in Arabidopsis lyrata
- 负责人：
- DOI：
- doi:10.5061/dryad.3gc6nj6
- 摘要：
- How the balance between selection, migration and drift influences the evolution of local adaptation has been under intense theoretical scrutiny
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
