Ray Hilborn of the University of Washington, Seattle, who wasn't involved, calls the finding "an important result" but suspects that the economic impact of restricting forage fishing will vary depending on the details of the fisheries.
Pastoral camel management practices in Kenya, characterised by free herd mobility that enables efficient utilisation of rangeland resources, is progressively restricted to foraging within the vicinity of urban milk market outlets.
The stabled (UK) or stalled (USA) horse is commonly fed a restricted-forage diet in contrast to the varied ad libitum high-fibre diet it evolved to consume.
One endangered and two common species of different body sizes, all of which restrict pollen foraging to a single plant genus, were established in a landscape lacking their specific host plants.
Karnovsky et al. (2003) reported that little auks (Alle alle) at Svalbard feed mainly on the large copepod (Calanus glacialis), restrict their foraging activity to Arctic water that contains this copepod, and avoid Atlantic water that contains a smaller copepod (Calanus finmarchicus).
During the breeding season, seabirds adopt a central place foraging strategy and are restricted in their foraging range by the fasting ability of their partner/chick and the cost of commuting between the prey resources and the nest.
Total diet DMI prepartum was higher for ad libitum than for restricted as designed, but forage source had no effect on DMI.
Furthermore, even when food was provided in excess, foraging was restricted to ~ 2 h after sunset in all treatments and the amount consumed per abalone was significantly lower at high densities.
Under natural conditions, insects are subjected to hours or days when foraging is restricted as a result of variable or inclement weather conditions.
As gannets typically remain on the continental shelf to forage (location of preferred prey; Fletcher and Tregonning, 1992), these much larger colonies are likely to have established mutually exclusive foraging zones stretching into Bass Strait, potentially restricting the foraging range of individuals from the Pope's Eye colony (Fig. 2).
Of these, 69% were never restricted and roamed freely to forage for food and mix with other dogs.
