- 摘要：
- In 2015, livestock scientists implementing Africa RISING research-in-development activities (R-in-D) introduced forage chopper machines in seve

- 摘要：
- More often than not, animals forage with other foragers present. A foraging game may take place when the outcome of a forager’s actions depends

- 摘要：
- Desert ants and honey bees start foraging when they are a few days old, and subsequently increase their foraging effort and the amount of forage
Data from: Aridity exacerbates grazing-induced rangeland degradation: a population approach for dominant grasses

- 摘要：
- native forage grass species common to the three sites. 3. Grazing decreased total grass density and increased the frequency of small plants in all sites
Data from: Food quality and quantity is more important in explaining foraging of an intermediate-sized mammalian herbivore than predation risk

- 摘要：
- . Forage quality and quantity was analysed based on hand-plucked samples of a selection of the locally most important plant species in the diet of hare. Predator

- 摘要：
- d, puffins foraged using tides to transport them through their feeding grounds. Energetic models suggest the cost of foraging trips using the drift stra
Data from: A breath of fresh air in the foraging theory: the importance of wind for food size selection in a central place forager

- 摘要：
- Empirical data about food size carried by central place foragers does not often fit with the optimum predicted by classical foraging
