- 摘要：
- and ecosystem functions. Quantifying niches of generalist predators can reveal how fragmentation alters ecosystems. In a habitat fragmentation experiment, we use
Data from: Energetic increases lead to niche packing in deep-sea wood falls

- 摘要：
- the environmental capacity to support species’ coexistence through increased niche packing or niche space expansion. Current ecological theory predicts increases
Data from: Trophic response to ecological conditions of habitats: evidence from trophic variability of freshwater fish
- 负责人：
- DOI：
- doi:10.5061/dryad.v15dv41s7
- 摘要：
- 1. The ecological niche is a fundamental concept for understanding the interaction among species that can change the function at the level of species
Data from: Importance of biotic niches versus drift in a plant-inhabiting arthropod community depends on rarity and trophic group
- 负责人：
- DOI：
- doi:10.5061/dryad.t5n8805
- 摘要：
- t, in contrast with common species, the occurrence of rare species will be poorly correlated with environmental variables (niches) and more affec
Data from: Widespread generalist clones are associated with range and niche expansion in allopolyploids of Pacific Northwest Hawthorns (Crataegus L.)

- 摘要：
- , and allopolyploids have the broadest niches. Allotetraploids have the largest niche and the widest geographic distribution. We then assessed the genetic mechanism
