Data from: Feces nitrogen release induced by different large herbivores in a dry grassland
- 负责人：
- Wang, Jingzhi
- DOI：
- doi:10.5061/dryad.7hn64
- 摘要：
- Large herbivores have pronounced effects on nutrient cycling in grasslands. These organisms are known to alter the quality and quantity
Data from: Long-term declines in dietary nutritional quality for North American cattle
- 负责人：
- Craine, Joseph
- DOI：
- doi:10.5061/dryad.n856r
- 摘要：
- the nutritional quality of forage. However, there are no analyses to quantify changes in diet quality, subsequent impact on cattle performance and cost of supplementation
Data from: Seagrass on the brink: decline of threatened seagrass Posidonia australis continues following protection
- 负责人：
- Suzanna M. Evans
- DOI：
- doi:10.5061/dryad.r9n52
- 摘要：
- Seagrasses are in decline globally due to sustained pressure from coastal development, water quality declines and the ongoing threat from
Data from: Grazer effects on soil carbon storage vary by herbivore assemblage in a semi-arid grassland

- DOI：
- doi:10.5061/dryad.ts80c92
- 摘要：
- ly in grasslands with abundant high quality forbs and high plant diversity, as sheep grazing may reduce soil carbon (C) storage. Moreover, mixed grazing, including
Data from: Reproductive success is energetically linked to foraging efficiency in Antarctic fur seals
- 负责人：
- Jeanniard-du-Dot, Tiphaine
- DOI：
- doi:10.5061/dryad.269qr
- 摘要：
- ween reproductive success and the quality of individuals as foragers provides an individual-based quantitative framework to investigate how changes in the availabili
Data from: Spatial correlations between browsing on balsam fir by white-tailed deer and the nutritional value of neighboring winter forage
- 负责人：
- DOI：
- doi:10.5061/dryad.f4245
- 摘要：
- forage selection is a hierarchical process, few studies have investigated associational effects at multiple spatial scales. Because the nutritional quality
Data from: Is ungulate migration culturally transmitted? Evidence of social learning from translocated animals
- 负责人：
- Jesmer, Brett R.
- 关键词：
- DOI：
- doi:10.5061/dryad.8165qv5
- 摘要：
- ungulate migrations evolve. Loss of migration will therefore expunge generations of knowledge about the locations of high-quality forage and likely suppress
Data from: Linking landscape-scale differences in forage to ungulate nutritional ecology
- 负责人：
- DOI：
- doi:10.5061/dryad.2hb22
- 摘要：
- of forage make it challenging to understand landscape-level effects of nutrition on ungulates. We developed an integrated spatial modeli
Data from: Behavior and nutritional condition buffer a large-bodied endotherm against direct and indirect effects of climate

- DOI：
- doi:10.5061/dryad.ss548
- 摘要：
- by the thermal environment were less pronounced, and elk selected areas that increased access to high quality forage over those that reduced costs of thermoregulation
Data from: The behavioral trade-off between thermoregulation and foraging in a heat-sensitive species

- 摘要：
- vegetation indices, and consumed lower quality forage, as indicated by lower levels of fecal crude protein. Ibex did not compensate behaviorally for reduced forage
