Data from: Species richness change across spatial scales
- 负责人：
- DOI：
- doi:10.5061/dryad.2jk717g
- 摘要：
- Humans have elevated global extinction rates and thus lowered global-scale species richness. However, there is no a priori reason to expect tha
Data from: What is behind the variation in mate quality dependent sex ratio adjustment? – A meta-analysis
- 负责人：
- DOI：
- doi:10.5061/dryad.5dh2q2b
- 摘要：
- Theory predicts that parents adjust the sex ratio of their brood to the sexually selected traits of their mate because the reproducti
Data from: Frequency-dependent selection acting on the widely fluctuating sex ratio of the aphid Prociphilus oriens
- 负责人：
- DOI：
- doi:10.5061/dryad.716hk
- 摘要：
- Frequency-dependent selection is a fundamental principle of adaptive sex-ratio evolution in all sex ratio theories but has rarely been detected
Data from: Arctic fungal communities associated with roots of Bistorta vivipara do not respond to the same fine-scale edaphic gradients as the above

- DOI：
- doi:10.5061/dryad.2343k
- 摘要：
- heterogeneous vegetation. We hypothesize that root-associated fungal (RAF) communities respond to the same fine-scale environmental gra

- DOI：
- doi:10.5061/dryad.14j2m
- 摘要：
- its to selection pressure. Using the Gaussian mixture model for the height/length ratio, a valve-shape parameter, we identified sexual differences in the valve shape
Data from: The geographical variation of network structure is scale dependent: understanding the biotic specialization of host-parasitoid networks

- ecological networks;host-parasitoid food web;beta-diversity;biotic specialization;spatial scale
- DOI：
- doi:10.5061/dryad.kk75k1p
- 摘要：
- the geographical variation in biotic specialization focus, however, only on the local scale. Little is known about how the geographical variation of network structure depends
Data from: Which landscape size best predicts the influence of forest cover on restoration success? – A global meta-analysis on the scale of effect
- 负责人：
- DOI：
- doi:10.5061/dryad.v1r34
- 摘要：
- sites (degraded or restored). Using an information-theoretic approach, mean response ratio (restoration success) and response ratio variance (restorati

- 负责人：
- DOI：
- doi:10.5061/dryad.v0q5p
- 摘要：
- Population sex ratio is an important metric for wildlife management and conservation, but estimates can be difficult to obtain, particular
Data from: Keeping things local: subpopulation Nb and Ne in a stream network with partial barriers to fish migration
- 负责人：
- DOI：
- doi:10.5061/dryad.s4td3
- 摘要：
- For organisms with overlapping generations that occur in metapopulations, uncertainty remains regarding the spatio-temporal scale of inference
