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.
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 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 ...
Kangaroo rats, small mostly nocturnal rodents of genus Dipodomys, are native to arid areas of western North America.The common name derives from their bipedal form. They hop in a manner similar to the much larger kangaroo, but developed this mode of locomotion independently, like several other clades of rodents (e.g., dipodids and hopping mice).
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.
The pineapple is an example of a CAM plant.. Crassulacean acid metabolism, also known as CAM photosynthesis, is a carbon fixation pathway that evolved in some plants as an adaptation to arid conditions [1] that allows a plant to photosynthesize during the day, but only exchange gases at night.
The most convenient distinguishing feature of the Arvicolinae is the nature of their molar teeth, which have prismatic cusps in the shape of alternating triangles. These molars are an adaptation to a herbivorous diet in which the major food plants include a large proportion of abrasive materials such as phytoliths; the teeth get worn down by abrasion throughout the adult life of the animal and ...
