Slowing metabolic rate to conserve energy in times of insufficient resources is the primarily noted purpose of torpor. [18] This conclusion is largely based on laboratory studies where torpor was observed to follow food deprivation. [19] There is evidence for other adaptive functions of torpor where animals are observed in natural contexts:
Rodentology is a branch of mammalogy for the study of rodents by a rodentologist. [1] The scientific group of rodents would include, but is not limited to, mice, rats, squirrels, etc. From the perspective of zoology , it investigates the behaviour, biology and classification of various rodent species.
Laboratory rats or lab rats are strains of the rat subspecies Rattus norvegicus domestica (Domestic Norwegian rat) which are bred and kept for scientific research. While less commonly used for research than laboratory mice, rats have served as an important animal model for research in psychology and biomedical science. [1]
The term rat is also used in the names of other small mammals that are not true rats. Examples include the North American pack rats (aka wood rats [3]) and a number of species loosely called kangaroo rats. [3] Rats such as the bandicoot rat (Bandicota bengalensis) are murine rodents related to true rats but are not members of the genus Rattus ...
While microscopic and invertebrate decomposers break down dead organisms into simple organic matter which are used by nearby autotrophs, scavengers help conserve energy and nutrients obtained from carrion within the upper trophic levels, and are able to disperse the energy and nutrients farther away from the site of the carrion than decomposers.
Scientists have for the first time ever found “shocking” evidence of carnivorous behaviour in squirrels — hunting and eating voles in California.. Ground squirrels are often seen stuffing ...
Rodents have been employed in biomedical experimentation from the 1650s. [1] Currently, rodents are commonly used in animal testing, particularly mice and rats, but also guinea pigs, hamsters, gerbils and others. Mice are the most commonly used vertebrate species, due to their availability, size, low cost, ease of handling, and fast ...
