Ecological interactions intimate association with biogeography. Yet ecology by definition deals with processes in ecological time, i.e. in the order of one to one hundred generations or years.

It is not surprising, therefore, that researchers in these diverse fields tend often to talk past, rather than to each other. This interdisciplinary nature has led to fragmentation rather than cooperation which has been to the detriment of the subject as a whole. T作者: 態(tài)度暖昧 時間: 2025-3-24 13:08

A more rigorous explanatory approach is to search for consistent patterns amongst the various species distributions and then use these patterns to discover the processes which underlie them. Indeed, the discovery of such processes is a prime function of biogeographic analysis.作者: 枯萎將要 時間: 2025-3-27 12:58

Relationship of species number to area, distance and other variablessequence of this is that, again in general, larger areas will contain more species than smaller areas. However, the species—area relationship is not simply a reflection of different distribution patterns. As will be seen, it can also arise from sampling a set of species all with the same distributions but with different abundances.作者: Myosin 時間: 2025-3-27 18:12
