Sentence examples for foraging advantage from inspiring English sources

In our experiment the first mover is a trained individual which possesses pertinent information (the location of food reward) giving it a foraging advantage.

While trichromats have a foraging advantage for red food compared with dichromats, some studies, support dichromat advantage for certain tasks, related to the effects of light intensity on foraging success among marmosets (Callithrix geoffroyi), as contributes to maintenance of the color vision polymorphism.

A large tail membrane will also potentially offer a foraging advantage for bats that use the tail membrane as an insect capturing pouch [17], presenting a large area with which to snare prey.

It has been demonstrated that dichromats are superior to trichromats in some visual tasks such as defeating cryptic coloration and motion detection [ 70, 85, 86] and have a foraging advantage for surface-dwelling insects [ 87- 89].

However, foraging advantages to trichromatic primates remain unverified by behavioral observation of primates in their natural habitats.

The evolution of the red-green visual subsystem in trichromatic primates has been linked to foraging advantages, specifically the detection of either ripe fruits or young leaves amid mature foliage, and to the intraspecific socio-sexual communication, namely the signal of the male rank, the mate choice and the reproductive strategies in females.

On the basis of the foraging hypothesis the advantage of trichromacy is the ability to see ripe fruits (orange or red) or edible leaves (dappled with red) against a background of mature foliage., Trichromatic vision is believed to be an important advantage in finding those palatable fruits or leaves.

A further advantage of foraging in sparse and short vegetation is a reduced risk of predation [22].

Other colorimetric studies incorporating nutritional measurements of primate diets support the trichromat advantage in foraging young leaves or fruits [25] [29].

Even a disadvantage of trichromacy has been suggested by behavioral experiments using capuchins (Cebus apella) and marmosets (Callithrix geoffroyi) for detecting color-camouflaged objects [41], [42] and a field study of capuchin monkeys (C. capucinus) has demonstrated a dichromat advantage in foraging for surface-dwelling insects [43].

To test whether release from predators has led to increased guppy population density and sharpened foraging traits, we took advantage of an introduction experiment initiated in 1976 where guppies were relocated from a site containing predatory fishes to a site lacking strong fish predators [30], [31].
