Webbthat size-selective predation affects the di- versity of predator as well as prey species in freshwater planktonic communities. This effect can be demonstrated in very simple … Size-selective predation: a lioness attacking a Cape buffalo, over twice her weight. Lions can attack much larger prey, including elephants, but do so much less often. Predators are often highly specialized in their diet and hunting behaviour; for example, the Eurasian lynx only hunts small ungulates . [76] Visa mer Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not … Visa mer While examples of predators among mammals and birds are well known, predators can be found in a broad range of taxa including … Visa mer To feed, a predator must search for, pursue and kill its prey. These actions form a foraging cycle. The predator must decide where to look for prey based on its geographical distribution; and once it has located prey, it must assess whether to pursue it or to wait … Visa mer To counter predation, prey have evolved defences for use at each stage of an attack. They can try to avoid detection, such as by using Visa mer At the most basic level, predators kill and eat other organisms. However, the concept of predation is broad, defined differently in different contexts, and includes a wide variety of feeding methods; and some relationships that result in the prey's … Visa mer Physical adaptations Under the pressure of natural selection, predators have evolved a variety of physical Visa mer Predators and prey are natural enemies, and many of their adaptations seem designed to counter each other.
