Data from: Sexual selection in complex communities: integrating interspecific reproductive interference in structured populations
- 负责人:
- DOI:
- doi:10.5061/dryad.j58b5t4
- 摘要:
- The social structure of populations plays a key role in shaping variation in sexual selection. In nature, sexual selection occurs in communities
Data from: The relationship between spatial structure and the maintenance of diversity in microbial populations
- 负责人:
- DOI:
- doi:10.5061/dryad.5670c6n
- 摘要:
- Spatial structure is pervasive in the microbial world, yet we know little about how it influences the evolution of microbial populations
Data from: Agonistic reciprocity is associated with reduced male reproductive success within haremic social networks

- DOI:
- doi:10.5061/dryad.n0h37
- 摘要:
- While individual variation in social behaviour is ubiquitous and causes social groups to differ in structure, how these structural differences affect
Data from: Generation time, net reproductive rate, and growth in stage-age structured populations

- 摘要:
- -structured populations. Here we generalize this result to populations structured by stage and age by providing a new, unique measure of reproductive timing (Tc) that, al
Data from: Non-equilibrium conditions explain spatial variability in genetic structuring of little penguin (Eudyptula minor)
- 负责人:
- DOI:
- doi:10.5061/dryad.v147d
- 摘要:
- Factors responsible for spatial structuring of population genetic variation are varied, and in many instances there may be no obvious explanations
Data from: Damage shielding mechanisms in hierarchical composites in nature with potentials in design of tougher structural materials
- 负责人:
- DOI:
- doi:10.5061/dryad.60vk297
- 摘要:
- Load-carrying materials in nature, such as wood and bone, consist of relatively simple building blocks assembled into a hierarchical structure
Data from: Detecting a hierarchical genetic population structure: the case study of the Fire Salamander (Salamandra salamandra) in Northern Italy

- 摘要:
- =0.006, p<0.001), the second group proved more structured being divided in four clusters (Global FST=0.017, p=0.058). This genetic population structure sh
Data from: The program STRUCTURE does not reliably recover the correct population structure when sampling is uneven: sub-sampling and new estimators

- DOI:
- doi:10.5061/dryad.2d4m9
- 摘要:
- Inferences of population structure and more precisely the identification of genetically homogeneous groups of individuals are essential to the fields
Data from: Fluctuations in age structure and their variable influence on population growth
