Olympic marmots can become more vulnerable to predators when daytime temperatures rise too high for foraging, causing them to forage in the cooler evenings when predators are more difficult to notice.
One may envisage that since foraging cause turbidity of suspended material, a walrus would have an advantage in positioning itself accordingly, that is, letting the current move the sediment away and behind the animal, all the time feeding and moving in a forward leading direction.
Birds breeding in cold environments regularly have to interrupt incubation to forage, causing a trade-off between two mutually exclusive behaviours.
For 65% of the interviewees, ash tree forage causes diarrhoea in sheep in spring when the leaves grow.
Crucially, in both studies deficits were not evident for at least two weeks, suggesting that toxicity may result from a deficit in bee foraging efficiency causing a limitation of brood production as reported previously, or by developmental defects in the brood.
Feeding more digestible forage caused thinner and longer faeces particles than did feeding low-digestibility forage.
We focus on daytime behaviour because this is the time when foraging cranes may cause crop damage and when preventive measures such as scaring and culling are conducted.
Overall, environmental effects may well have a very strong influence in the field and may cause foraging to be unevenly distributed in a colony's territory, with their influence affecting not just naïve ants or the initial discovery of a feeding location.
Honeybee foragers (Apis mellifera) have higher levels of expression of foraging than nurse bees and treatment with cGMP causes precocious foraging in young bees [ 7].
