trategies determined from various ecological optimization criteria. Specifically, one common type of optimum ecological strategy maximizes the abundance of a population. In ecology it is natural to ask what strategies of resource use and allocation will lead to the highest population size, i.e., wha止痛药 发表于 2025-3-24 00:36:34

The potential for variables such as temperature, pH, litter palatability and dispersal, to limit or promote the invasion of exotic earthworms in Canadian forests is discussed, and areas for future research are proposed.
