- DOI：
- doi:10.5061/dryad.p4h15
- 摘要：
- seasonal changes in diet breadth and forage selection of adult female desert bighorn sheep Ovis canadensis mexicana in relation to potential nutritional limita

- DOI：
- doi:10.5061/dryad.2kf78h8
- 摘要：
- Niche breadth is predicted to correlate with environmental heterogeneity, such that generalists will evolve in heterogeneous environments
Data from: Co-evolution of cerebral and cerebellar expansion in cetaceans

- DOI：
- doi:10.5061/dryad.rm4368f
- 摘要：
- that their expansion may be associated with dietary breadth. In addition, our results suggest that major increases in both cerebrum and cerebellum size
Data from: The evolution of novel host use is unlikely to be constrained by tradeoffs or a lack of genetic variation

- DOI：
- doi:10.5061/dryad.7b5m7
- 摘要：
- basis. We documented very few genetic variants with trade-offs that would inherently constrain diet breadth by preventing the optimization of performance
Data from: Does intraspecific competition promote variation? A test via synthesis

- DOI：
- doi:10.5061/dryad.h61dj
- 摘要：
- sing intraspecific competition had a restricting effect on population-level diet breadth in as many cases as it had a diversifying effect. This wide disparity in the effect
Data from: Reconstructing hyperdiverse food webs: gut content metabarcoding as a tool to disentangle trophic interactions on coral reefs
- 负责人：

- DOI：
- doi:10.5061/dryad.t7pd371
- 摘要：
- ng species is critical. However, this requires both exceptional resolution in dietary assessments and sampling breadth within communities, esp
