metapopulations植物学含义metapopulations 在植物学中,集合种群(metapopulation)也被称为异质种群。 集合种群是指一个大的、兴旺的种群因环境污染、栖息地破坏或其他干扰而破碎成许多孤立的小种群时,这些小种群的联合体或总体就称为集合种群。©2022 Baidu |由 百度智能云 提供计算服务 | 使用百度前必读 | 文库协议...

The genetic structure of metapopulations offers insights into the genetic consequences of local extinction and recolonization. We studied allozyme variation in rock pool metapopulations of two species of waterfleas () with the aim to understand how these dynamics influence genetic differentiation. We scr...

METAPOPULATIONSDAG ØYSTEIN HJERMANNUniversity of Oslo, NorwayMetapopulations are “populations of populations”— collections of island populations bound loosely together by occasional migration between the islands. Metapopu-lation theory has been applied to terrestrial environments (where the “islands” ...
Metapopulations and the Atlantic herring Abstract Two opposing concepts of Atlantic herring, Clupea harengus L., population structure are critically reviewed with the objective of unifying these divergent views under the metapopulation concept. It is concluded that neither the discrete population concept ...

A tribute to Ilkka Hanski. Empirical data modelling shows that molecular variation at a candidate gene within populations has consequences for metapopulation size and persistence.
