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]

[2] The term hoarding is most typically used for rodents, whereas caching is more commonly used in reference to birds, but the behaviors in both animal groups are quite similar. Hoarding is done either on a long-term basis—cached on a seasonal cycle, with food to be consumed months down the line—or on a short-term basis, in which case the ...
The Polynesian rat, Pacific rat or little rat (Rattus exulans), or kiore, is the third most widespread species of rat in the world behind the brown rat and black rat.Contrary to its vernacular name, the Polynesian rat originated in Southeast Asia, and like its relatives has become widespread, migrating to most of Polynesia, including New Zealand, Easter Island, and Hawaii.
This test proved it was oxygen, or, as Joseph Priestley had called it, 'de-phlogisticated air'. In 1932, Robert Emerson and his student, William Arnold, used a repetitive flash technique to precisely measure small quantities of oxygen evolved by chlorophyll in the algae Chlorella. Their experiment proved the existence of a photosynthetic unit.
Rodents are animals that gnaw with two continuously growing incisors. Forty percent of mammal species are rodents, and they inhabit every continent except Antarctica. This list contains circa 2,700 species in 518 genera in the order Rodentia. [1]
The δ 13 C of C3 plants depends on the relationship between stomatal conductance and photosynthetic rate, which is a good proxy of water use efficiency in the leaf. [19] C3 plants with high water-use efficiency tend to be less fractionated in 13 C (i.e., δ 13 C is relatively less negative) compared to C3 plants with low water-use efficiency. [19]
