From regionally predictable to locally complex population structure in a freshwater top predator: river systems are not always the unit of connectivity in Northern Pike Esox lucius          下载免费PDF全文

Contemporary genetic diversity is the product of both historical and contemporary forces, such as climatic and geological processes affecting range distribution and continuously moulded by evolutionary forces selection, gene flow and genetic drift. Predatory freshwater fishes, such as Northern Pike Esox lucius, commonly exhibit small population sizes, and several local populations are considered endangered. Pike inhabit diverse habitat types, including lakes, rivers and brackish marine waters, thus spanning from small isolated patches to large open marine systems. However, pike population structure from local to regional scales is relatively poorly described, in spite of its significance to developing conservation measures. We analysed microsatellite variation in a total of 1185 North European pike from 46 samples collected across both local and regional scales, as well as over time, to address two overarching questions: Is pike population structure associated with local and/or regional connectivity patterns, and which factors likely have the main influence on the contemporary distribution of genetic diversity? To answer this, we combined estimators of population diversity and structure to assess evidence of whether populations within (i) habitats, (ii) drainage systems and (iii) geographical regions are closer related than among these ranges, and whether patterns are temporally stable. Contrasting previous predictions that genetic drift obscures signals of postglacial colonisation history, we identified clear regional differences in population genetic signatures, suggesting a major effect of drainage divides on colonisation history and connectivity. However, several populations deviated from the general pattern, showing that local processes may be complex and need to be examined case‐by‐case.  相似文献

植物文化性及其在园林景观中表达的研究   总被引：1，自引：0，他引：1  

胡晓梅  黄成林  张云彬 《农业科技与信息》2011,(4)

随着人类文明的不断进步,人类社会的不断发展,文化的地位越发显得举足轻重。形成了许多独特的文化体系。如茶文化、企业文化等等名词渐渐为人们所熟悉。于是,越来越多的人在越来越多的领域开始关注文化,研究文化。文化也变得流行起来,并且渗透到了园林景观的领域。植物是园林景观的重要组成部分,植物配置的水平在一定程度上决定了园林景观设计的优劣程度。在景观建设不断发展的今天,植物的文化性作为考察植物配置水平的重要因素,越来越引起景观工作者的重视。在不同的园林景观环境中,合理的利用植物文化性能够体现整体环境的文化氛围。让人们在自然环境中品味文化,达到提升审美情趣,感悟世界观、人生观和了解人文历史的目的。目前,对于植物文化性的概念还没有统一的定义。本篇论文目的在于对植物文化性的概念进行定义,并且在此基础上,创新性的提出植物文化性的分类和评价依据。最后,引入在不同地域环境中,植物文化性的实例分析,对植物文化性展开讨论。旨在使读者系统的了解植物的文化性,弘扬民族文化,使园林工作者在植物配植造景中更好的运用植物的文化性。  相似文献

Application of body size spectra to nematode trait-index analyses     

《Soil biology & biochemistry》2015

Current trait-based indices of soil fauna for assessing soil quality rely on extensive knowledge of life history traits for hyper-diverse groups. We look at the effects of clear-cut forest harvesting and subsequent wood ash application on the free-living nematode community using trait-based indices and body size spectra. We test the hypothesis that body size is a unifying trait and that the body size spectra can be used to demonstrate changes in soil quality while overcoming taxonomic impediments. Undisturbed boreal forest floor soils were compared with clear-cut sites amended with zero, one-half calcium equivalent wood ash, equivalent calcium reintroduction, and twice calcium reintroduction. Total abundance, trait-based metrics for the Maturity Index, and two metrics of body size spectra were calculated. Nematode abundance was not a good indicator of soil disturbance, while traditional trait-based approaches (the summed Maturity Index) demonstrated predicted changes in community structure. Analysis of two types of body size spectra elucidated how the community had changed under disturbance, and revealed that smaller bodied organisms were lost under ash amended treatments compared to both clear-cut and undisturbed forest. Using the body size spectra for nematodes is a simple addition to current trait-based approaches that can supplement soil assessments for disturbance and quality without requiring taxonomic expertise.  相似文献
