Data from: The nutritional balancing act of a large herbivore: an experiment with captive moose (Alces alces L)
- 负责人：

- DOI：
- doi:10.5061/dryad.857dd
- 摘要：
- hypothesis, as the moose combined the foods in specific proportions that provided a particular ratio and amount of macronutrients. When restricted to either
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：
- y large fracture surfaces indicating energy dissipation by cracking on multiple length scales. Manmade composites instead consists typically of fibres
Data from: House sparrows offset the physiological trade-off between immune response and feather growth by adjusting foraging behavior
- 负责人：
- 关键词：
- DOI：
- doi:10.5061/dryad.4d2r7
- 摘要：
- an immune response during feather growth may divert energy and resources from feather growth and impair feather renewal. To test this hypothesis, we clipped or plucked
Data from: Evidence for locally adaptive metabolic rates among ant populations along an elevation gradient

- climate change common garden experiment metabolic cold adaptation hypothesis phenotypic plasticity thermal performance social insect
- DOI：
- doi:10.5061/dryad.3hv2826
- 摘要：
- support for the metabolic cold adaptation hypothesis highlights that while organisms likely show a wealth of unexplored metabolic temperature plasticity
Data from: Brain size and the expression of pheomelanin-based colour in birds
- 负责人：
- DOI：
- doi:10.5061/dryad.8262
- 摘要：
- e we tested this hypothesis in a large dataset of 323 bird species. After controlling for the effects of phylogeny, latitude and sexual dichromatism
Data from: Convergence in reduced body size, head size, and blood glucose in three island reptiles
- 负责人：
- DOI：
- doi:10.5061/dryad.k6k2g1q
- 摘要：
- lie these changes, and whether they are convergent. A major hypothesis for the repeated evolution of dwarfism posits selection for smaller, more efficient
Data from: Trophic niche size and overlap decreases with increasing ecosystem productivity
- 负责人：
- DOI：
- doi:10.5061/dryad.xwdbrv1b3
- 摘要：
- tent with the hypothesis that increasing productivity allows species to focus on a narrower diet. This pattern describes the relationship between ecosystem production
Data from: Molecular characterization and population structure of the macaw palm, Acrocomia aculeata (Arecaceae), ex situ germplasm collection usi
- 负责人：
- DOI：
- doi:10.5061/dryad.6f64b
- 摘要：
- ns of the distribution of the allelic diversity of A. aculeata ex situ germplasm collection, the present study investigated the hypothesis that the gene
Data from: The biogeographical patterns of species richness and abundance distribution in stream diatoms are driven by climate and water chemistry
- 负责人：
- DOI：
- doi:10.5061/dryad.v1v7856
- 摘要：
- and the climatic tolerance hypothesis) but found no support for any of these concepts as the relationships of richness with explanatory variables were non-existent
Data from: Acquisition of germ plasm accelerates vertebrate evolution.
- 负责人：
- DOI：
- doi:10.5061/dryad.rd70f
- 摘要：
- tic incongruence in protein-coding sequence comparisons between vertebrate taxa. Our results support the hypothesis that germ plasm liberates constraints on somatic development
