Data from: Effective size in density-dependent two-sex populations: the effect of mating systems
- 负责人：
- Myhre, Ane Marlene
- 关键词：
- 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：
- drift compared to an equal, density independent sex ratio, but a stochastic change towards male-bias reduces the Ne/N ratio. Environmental stochasticity amplifies
Data from: Chaos and the (un)predictability of evolution in a changing environment
- 负责人：
- DOI：
- doi:10.5061/dryad.pg570
- 摘要：
- much less attention than randomness due to genetic drift or environmental stochasticity. It was recently shown that chaos in phenotypic evolution arises

- 摘要：
- ons in pollination networks by using a hybrid model that combined a recently developed stochastic coextinction model (SCM) for plant extincti
Data from: Local interactions and self-organized spatial patterns stabilize microbial cross-feeding against cheaters
- 负责人：
- DOI：
- doi:10.5061/dryad.s1v3801
- 摘要：
- how cross-feeders remain robust to non-producing cheaters have relied on complex behavior (e.g., cheater punishment) or group selection. Using a stochastic
Data from: Multi-scale drivers of community diversity and composition across tidal heights: an example on temperate seaweed communities
- 负责人：
- DOI：
- doi:10.5061/dryad.3s96n
- 摘要：
- ng randomised community matrices and Moran’s eigenvector maps (MEMs), we compared i) the relative importance of deterministic and stochastic processes, ii

- 摘要：
- ) and temporal variability (inter-annual) can make it difficult to separate intrinsic, extrinsic, and stochastic drivers of phenological variability. The goal of this study
Data from: Matching habitat choice promotes species persistence under climate change
- 负责人：
- DOI：
- doi:10.5061/dryad.rm93865
- 摘要：
- . We also found that environmental stochasticity resulted in suboptimal matching habitat choice, decreasing the benefits of this dispersal mode under
Data from: Nonselective bottlenecks control the divergence and diversification of phase-variable bacterial populations
- 负责人：
- DOI：
- doi:10.5061/dryad.p46n0
- 摘要：
- food-borne pathogen, contain multiple phase-variable loci whose rapid, stochastic variation is generated by hypermutable simple sequence repeat tracts. These loc
Data from: Evidence for a stochastic geometry of biodiversity: the effects of species abundance, richness and intraspecific clustering
- 负责人：
- DOI：
- doi:10.5061/dryad.mf02n
- 摘要：
- Most ecological theories that aim to explain coexistence in megadiverse communities employ a set of three rules to describe the stochastic
Data from: Temporal genetic structure in a poecilogonous polychaete: the interplay of developmental mode and environmental stochasticity

- 摘要：
- on, stochastic environmental variation, migration, or genetic drift. In benthic marine species, the developmental mode of larvae may indicate a possibility for temporal genetic variati
