In a broad perspective, irrespective of the difficulty of testing largely unreproducible phenomena such as historical contingency (Gould 1989), consideration of both evolutionary and contemporary processes is crucial to a better understanding of t无情 发表于 2025-3-27 12:21:05

Yin Shen,Gerrit Voordouwes pest damage by making it difficult for specialist insects to move from host to host (Andow 1991). In this chapter, an example in which botanical diversity poses a problem for an herbivorous insect is reviewed. The nature of the insect’s predicament is described and behavioral strategies employed门窗的侧柱 发表于 2025-3-27 21:28:42

Mary Beth Leigh,Lee Taylor,Josh D. Neufeld that these days very few experienced ecologists would doubt that species diversity not only stabilises the functional parameters of a guild (production, total biomass, etc.) but also tends to maximise these parameters in the process of self-arrangement, of course, to the extent possible with the avreceptors 发表于 2025-3-28 14:02:37
