Data from: Native forage mediates influence of irrigated agriculture on migratory behavior of elk
- 负责人：
- Barker, Kristin
- 摘要：
- 1. Ungulates migrate to maximize nutritional intake when forage varies seasonally. Populations of ungulates often include both migra
Data from: The effect of conspecific density on honey bee foraging behavior
- 负责人：
- 摘要：
- Foraging honey bees (Apis mellifera) seem to use the presence of conspecific foragers as cues for flower quality. However, there is disagreement rega
Data from: Extreme precipitation variability, forage quality and large herbivore diet selection in arid environments
- 负责人：
- 摘要：
- in forage N, moisture and energy content (as proxied by dry matter digestibility, DMD). Succulents were consistently high in moisture but low in N and grasse
Data from: Where to forage when afraid: Does perceived risk impair use of the foodscape?

- 摘要：
- Forage-Loss Hypothesis, wherein behavioral avoidance is predicted to reduce use of available forage adjacent to disturbance. We used GPS-collar
Data from: Grazer effects on soil carbon storage vary by herbivore assemblage in a semi-arid grassland

- plant diversity foraging behaviour soil organic carbon livestock grazing grassland management carbon cycle plant-herbivore interactions
- 摘要：
- . Livestock grazing management can substantially affect grassland soil carbon (C) storage, but few controlled experiments have explored how herbivore assemblages (diffe
Data from: Foraging mode, relative prey size and diet breadth: a phylogenetically-explicit analysis of snake feeding ecology
- 负责人：
- Glaudas, Xavier
- 摘要：
- relative meal size compared to actively foraging snakes which feed on smaller prey items. This “large meal vs. small meal” feeding hypothesis between ambush
Data from: Public-private partnership wetland restorations provide quality forage for waterfowl in Northern New York
- 负责人：
- 关键词：
- 摘要：
- Valley of New York. We conducted surveys at 47 restored and 18 reference wetlands to characterize the vegetation assemblage in terms of its value as forage
Data from: Local forage fish abundance influences foraging effort and offspring condition in an Endangered marine predator

- per trip, number of foraging dives and the maximum distance travelled) increased and offspring body condition decreased as forage
Data from: The utility of normalized difference vegetation index for predicting African buffalo forage quality
- 负责人：
- 摘要：
- tation Index (NDVI) as a proxy for forage quality. The assumption that reflected greenness represents forage quality often goes untested, and limited data exist
Data from: Elevated CO2 induces substantial and persistent declines in forage quality irrespective of warming in mixedgrass prairie
- 负责人：
- 摘要：
- in a semiarid, mixedgrass prairie. For the 3 dominant forage grasses, warming effects on in vitro dry matter digestibility (IVDMD) and tissue [N] were detected
