Open or closed? Dispersal and recruitment in populations of aquatic invertebrates with spatially distributed resources

开放还是关闭？具有空间分布资源的水生无脊椎动物种群的扩散和补充。这项研究的总体目的是检查的贡献，受精卵和最近孵化的青少年的当地人口动态的一些流无脊椎动物。这些阶段似乎是种群的“瓶颈”，我们的研究将量化这两个阶段之间以及新生幼虫和成熟幼虫之间的关系。我们的研究还将表明这些人群是否可能被关闭（即，个体的组相对隔离）沿沿着通道或不沿通道。我们相信，我们的研究结果将表明，许多河流研究集中在错误的生命阶段，河流管理的做法可能需要重新评估。

Open or closed? Dispersal and recruitment in populations of aquatic invertebrates with spatially distributed resources. The general aim of this research is to examine the contribution of fertilised eggs and recently hatched juveniles to the local population dynamics of some stream invertebrates. It seems likely that these stages act as population 'bottlenecks' , and our research will quantify the relations between these two stages and between neonates and mature larvae. Our research will also indicate whether these populations are likely to be closed (i.e., groups of individuals are relatively isolated) along channels or not. We believe our results will show much stream research focuses on the wrong life-stages; practices of river management may need re-assessment.
