Browsing is a type of predation in which a herbivore or, more narrowly defined, a folivore feeds on leaves , soft shoots , or fruits of high growing, generally woody, plants such as shrub s. ref Chapman, J.L. and Reiss, M.J., em Ecology Principles and Applications em . Cambridge, U.K. Cambridge University Press, 1999. p. 304. via Google books, Feb 25, 2008 ref This is contrasted with grazing predation, usually associated with animals feeding on grass or other low vegetation. An example of this dichotomy are goat s which are browsers and Domestic sheep sheep which are grazers these two closely related ruminant s utilize dissimilar feeding preferences.

In time of drought, herdsmen may cut branches from beyond the reach of their stock, as forage at ground level. In the tropical regions, where population pressure leads owners to resort to this more often, there is a danger of permanent depletion of the supply. Animals in captivity may be fed browse as a replacement for their wild food sources in the case of bear bears , the browse may consist of bunches of banana leaves, bamboo shoots, slender pine, spruce, fir and willow branches, straw and native grasses. ref http www.animalsasia.org emailupdate html emailUpdate HK 02052010 valentine.html?tkn m1020994&eid 689&sou AL10MBRVANEM&b html Buy a bunch of browse for the bears , Animals Asia ref Also See Consumer resource systems Herbivore References references Feeding ecology stub Category Herbivory Category Fodder ... more details

File Spider and fly April 2008 6.jpg thumb A female goldenrod crab spider Misumena vatia capturing a pair of mating flies. This species can change colour to match the flower. Ambush predators or sit and wait predators are carnivore carnivorous animals that capture prey by stealth or cunning, not by speed or necessarily by strength. These organisms usually hide motionless and wait for prey to come within striking distance. They are often camouflage d, and may be solitary. This mode of predation may be most efficient when a predator cannot move faster than its preferred prey otherwise, active hunting is more efficient. ref cite journal author Inon Scharf, Einat Nulman, Ofer Ovadia & Amos Bouskila year 2006 title Efficiency evaluation of two competing foraging modes under different conditions journal The American Naturalist volume 168 issue 3 pages 350 357 url http www.bgu.ac.il oferovad library Scharf06ForMod.pdf doi 10.1086 506921 ref Ambush predators include many fish , snakes , and other reptiles e.g. crocodile s , as well as some mammal s, bird s, and spider s.

expert date February 2011 Chemical defense is the use of compounds by plants and animals to deter herbivory and predation . In plants Main Plant defense against herbivory Chemical defense against herbivory is common. The production of capsaicin in many strains of bell pepper s is one such defense familiar to humans. In animals Chemical defense is most common in insects , but the skunk is a particularly dramatic mammal ian example. Other examples include the Bombardier beetle which can accurately shoot a predator with a stream of boiling poison, the Ornate moth which excretes a frothy alkaloid mixture, and the Pacific beetle cockroach sprays a quinone mixture from modified spiracle s. ecology stub Category Evolutionary biology Category Herbivory Category Predation ... more details

Eggs, with a chorion , are retained within the female s body and are nourished through milk glands until the developed larvae are ready to pupate . The larvae are then larviposited and immediately pupate. This is one way insects avoid predation during their most vulnerable life stage. References references Peter Price Insect Ecology, 3rd. ed.
