Land use and land cover change have been of great concern in global change research in recent years. Base on comparison with the remote sensing data in1982 and 2000 and field investigation, the results of land cover and land use change were obtained by the method of landscape analysis. Ten types of land use were identified: riparian woods, riparian shrubbery, desert shrubbery, desert grassland,...

Since the late 1970s, Southern Hemisphere semi-arid regions such as southern-coastal Chile, southern Africa, and southeastern Australia have experienced a drying trend in austral autumn, predominantly during April and May. The rainfall reduction coincides with a poleward expansion of the tropical belt and subtropical dry zone by around 2°-3° in the same season. This has raised questions as to w...

Mountain ungulates of the subfamily Caprinae, including wild sheep, goats and goat-antelopes, show remarkable interspecific diversity in habitat preferences, social organisation morphological features. We review how this relates to their mating behaviour. After introducing ecology systems evolution we investigate pairwise, sequential relationships between behaviour, level polygyny, features, di...
