Thus there are no New Zealand snakes, and bats, which flew there, and seals, which swam there, were the only mammals on New Zealand when Polynesian settlers (the Maori) arrived there about a thousand years ago. [#paragraph2]When the Maori arrived in New Zealand, they encountered birds ...

Conservation in New Zealand is largely focused on reducing the impact introduced mammals have on the abundance of indigenous species. Conservation managers have a range of strategies they can employ to control these pests, but the combination that maximises conservation gains depends on the protection ...
Ecologist Paul S.Martin has championed the model that associates the extinction of large mammals at the end of the Pleistocene with human predation. [#highlight6]With researcher J.E.Mosimann, he has co-authored a work in which a computer model showed that in around 300 years, given the ...
Mammals, including humans, have an internal timing mechanism called the biological clock which controls circadian rhythms on physiology, biochemistry and molecular events. We all know how screwed up our system gets when we fly across time zones. It has now been shown that plants do have a intern...
The fruits of dogwoods are eaten by mostly birds, but also by rodents and other mammals (Eyde, 1988). There is no clear evidence for color preference (e.g., white fruits of C. alba Linn. Mant. and black fruits of C. sanguinea L. are both eaten by European redstarts), but there ...

Rabbits are a good alternative to larger mammals for meat production and, thus, an adequate alternative source for the increasing population in developing countries [1]. Rabbits are characterized by high reproductive performance compared to that of other farm animals; unfortunately, they are sensitive...
Responses of plant communities to mammalian herbivory are typically investigated with exclosure experiments [35,36,37,38], where plant densities or species occurrences within a fence (mammals/ungulates excluded) are contrasted against an open control plot that mammals have access to. Comparing exclosur...
