Advances in thermal physiology of diving marine mammals: The . . . While mammals typically have subcutaneous fat, most marine mammals have a specialized blubber layer composed of adipose tissue reinforced by collagen and elastin [20,21] The fully aquatic marine mammals, such as whales and dolphins (i e cetaceans), are the prime example of transitioning to this morphological adaptation They rely solely on

Invasive rats on tropical islands: Their population biology . . . Most research on the island biology and impacts of invasive rats has been conducted in temperate islands, principally New Zealand (inter alia Harper et al , 2005, Russell et al , 2005, Towns et al , 2006), with some notable exceptions being work in the northern Pacific, the Galápagos and Mexico (inter alia Tomich, 1970, Wirtz, 1972, Clark, 1980, Harris and McDonald, 2007, Samaniego-Herrera
Researchers propose two new killer whale species - Los . . . Names aside, he expects most marine mammalogists will be on board with the proposed species; many have suspected species-level differences among the well-studied whales of the Pacific Northwest
Ungulates: Hoofed Mammals - University of California Museum . . . The two major groups of living hoofed mammals are the Artiodactyla, or cloven-hooved mammals; and the Perissodactyla, or odd-toed mammals The former is by far larger of the two groups, with over a hundred living species, including such familiar animals as sheep, goats, camels, pigs, cows, deer, and antelopes
