项目摘要
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.
这项研究的总体目的是检查受精卵和最近孵化的幼崽对一些河流无脊椎动物当地种群动态的贡献。这些阶段似乎很可能是种群的“瓶颈”,我们的研究将量化这两个阶段之间以及新生儿和成熟幼虫之间的关系。我们的研究还将表明,这些种群是否可能沿着河道被封闭(即,个体群体相对孤立)。我们相信,我们的研究结果将表明,许多流研究关注的是错误的生命阶段;河流管理的做法可能需要重新评估。
