系统发生的接近性能解释互利生态系统中的嵌套性吗？
Does Phylogenetic Proximity Explain Nestedness in Mutualistic Ecosystems?
摘要：
我们研究了互惠生态系统中物种之间的接触模式是如何受到每个公会物种之间的系统发育接近性的影响。我们开发了一个动力学模型，旨在建立这种接近的嵌套模式的接触中出现的作用。我们还定义了一个参数，提供了一个直接的测量系统发育接近的影响，在一个给定的模式的接触。我们的结论是，虽然系统发育的接近是兼容的嵌套它不能被声称是它的原因，我们发现，嵌套反而可以归因于一个一般的规则，即物种倾向于与已经有大量的接触对应物保持联系。如果将两个公会的系统发育结构纳入分析，则该规则相当于最大化任一公会物种的互惠对应物的系统发育多样性。
英文摘要：
We investigate how the pattern of contacts between species in mutualistic ecosystems is affected by the phylogenetic proximity between the species of each guild. We develop a dynamical model geared to establish the role of such proximity in the emergence of a nested pattern of contacts. We also define a parameter that provides a direct measure of the influence of phylogenetic proximity in a given pattern of contacts. We conclude that although phylogenetic proximity is compatible with nestedness it can not be claimed to be a cause of it. We find that nestedness can instead be attributed to a general rule by which species tend to hold contacts with counterparts that already have a large number of contacts. If the phylogenetic structure of both guilds is brought into the analysis, this rule is equivalent to maximize the phylogenetic diversity of the mutualistic counterparts of species of either guild.
