Additional evidence supporting a role for melanization in water conservation comes from a study of D. polymorpha populations in Brazil (Brisson et al., 2005). Dark flies were most abundant in open, dry environments, despite the fact that these were warmer than more humid forest habitats, where light flies predominated. In this case, melanization patterns were opposite to those expected for thermal regulation, but consistent with a role in water conservation. Thus, in combination with studies by Parkash and colleagues, there is increasing evidence that melanization significantly affects water balance, at least in Drosophila. The fact that transitions in water-loss can be observed in solvent-extracted animals (Yoder and Tank, 2006) also supports a role for non-lipid layers in determining... 

Some North American examples cf tree-sized legumes that occur in temperate climates include the black locust Robinia pseudoacacia, yellow-wood Cladrastis luted, redbud Cercis canadefisis, haiey locust Gleditsia triacanthos, and Kentucky coffee tree GyninocloAus dioica. These are all native to parts of the eastern United States but are cultivated as ornamentals more widely, sometimes escapii into roadside and seccndaiy-forest habitats. 

The main protection that lorisids have from direct harm by humans is that they are so difficult to see. Thus they are not hunted as larger monkeys are. However, their forest habitat is readily degraded... 

Marmosets and tamarins are South and Central American primates of the Amazon Basin. Their family, Cal-litrichidae, includes 18 species that have been described as near -monkeys. All species are considered endangered or threatened by extinction. This plight is mostly caused by deforestation to develop new agricultural land, as well as disturbance of their forest habitat by logging, road construction, hunting, and other human activities. 

The western Australian native cat or western quoll (Dasyurinus geojfroyi) only occurs in remnants of its formerly extensive range of open-forest habitats, having been widely extirpated by introduced diseases and predators, hunters, and other factors. 

Yard—A wintertime, forested habitat of certain species of deer, generally dominated by coniferous trees and having a relatively shallow accumulation of snow. 

Other endangered species include the southern bearded saki Chiropotes satanas, the yellow-tailed woolly monkey Lagothrix flavicauda), and the Central American squirrel monkey Saimiri oerstedii). As more and more of the rain forest is cleared, other New World monkeys will be added to the endangered species list. The only ways to save these endangered primates are to preserve their natural forest habitat, and to control the hunting of the rarer species. 

For centuries, mankind has searched for the cure of illnesses in herbs. In that sense, approximately one third of drugs actually in use are from plant origin [1]. In the last decades, however, most of the drugs incorporated to the therapeutic arsenal come from synthetic sources. Nevertheless, in recent years a remarkable interest in the study of medicinal plants has appeared, mainly due to the concern about the destruction of rain forest habitats, with the risk of extinction of numerous species. Another fact is the loss of the knowledge related to the use of plant remedies by the people from native settlements, that is very common when they are incorporated to the urban life, and/or when their environmental conditions are seriously transformed. 

Nematode species richness, in contrast with the general rule valid for most animals and plants, reaches its maximum at higher latitudes. For example, a comparison of 18 soil samples gives an average of 81 species (range 33-162) in the tundra habitats, 56 species (31-95) in temperate grassland and forest habitats and 18 species (12-24) in tropical habitats.
