G. W. Bury has been making a collection of mammals and birds in the high country to the north of Aden, on the borders of Yemen. Among the specimens so obtained are three genets (the genus Oenetta not having been previously recorded from Arabia), a new Meriones, and examples of the ...
There is consensus, however, that once land is converted for human use, bats (and other mammals) encounter other species more closely, providing opportunities for viruses to jump between them. Bats, in particular, can be driven close to human habitation because of artificial light, fruit orchards...
the forest floor is covered in dead plant matter, while in winter, snow covers the landscape. Some mammals have adapted to be camouflaged in both seasons. Thesnowshoe harehas brown fur during the summer months, which allows it to blend into dirt and evade the eyes of predators....
But some groups, like fish and crustaceans, have member species that exist in different groups of factors. For example: dugongs eat seagrasses, while some species of seal eat penguins and fish, yet both are mammals. While some of these species may seem at odds, like a killer whale and it...
The Sailfish and the swordfish are both examples of billfish, or fish with beaks that have been elongated to resemble spears or lances. To a casual observer, the swordfish and sailfish look alike, and both are prized as game fish and make good eating. Females of both species produce ...
Findings: Climate change can drive some species of migrating animals towards extinction. Reason: Birds, mammals and reptiles are finding it increasingly difficult to follow their usual migrating patterns. Examples: 1. The spreading Sahara Desert could make it impossible for swallows to make the epic...
Human beings share the basic mamma- lian brain plan, and many features of the brain, as a cybernetic sys- tem, are shared with nearly all vertebrates. Comparing the human brain with those of other mammals reveals that our cerebral cortex has been greatly expanded by evolution, but the ...
Protistsare mostly single-celled organisms that have a nucleus. They usually live in water. Some protists move around, while others stay in one place. Examples of protists include some algae, paramecium, and amoeba. Fungi Fungiare usually motionless organisms that absorb nutrients for survival. ...
Hautai Marine Reserve includes representative examples of a variety of southern latitude West Coast marine habitats lying on the inshore margins of a complex submarine landscape of canyons and rocky reefs. This section of coast has habitats of high wildlife value, including marine mammals and seabirds...
Overview of cichlid (n = 6) choices in all three transfer tests. (a) Transfer test type A; (b) Transfer test type B; (c) Transfer test type C. Schematic examples on which the individuals based their choice are presented on the x-axis. Stimuli in the dashed box show the test ...
