Macroinvertebrate communities along a third-order Iberian stream
Many studies have tried to elucidate the main factors influencing macroinvertebrate community composition and abundance in streams (e.g. Hart 1992, Dudgeon 1994, Giller & Twomey 1993, Maridet et al. 1998, Tierney et al. 1998, Pardo 2000, Doisy & Rabeni 2001). Considerable attention has been paid to food resources (e.g. Hawkins & Sedell 1981, Cowan & Oswood 1984, Boulton & Lake 1992, Friberg 199...
متن کاملDiversity of Eastern North American Ant Communities along Environmental Gradients
Studies of species diversity patterns across regional environmental gradients seldom consider the impact of habitat type on within-site (alpha) and between-site (beta) diversity. This study is designed to identify the influence of habitat type across geographic and environmental space, on local patterns of species richness and regional turnover patterns of ant diversity in the northeastern Unit...
متن کاملthe role of russia in transmission of energy from central asia and caucuses to european union
پس ازفروپاشی شوروی،رشد منابع نفت و گاز، آسیای میانه و قفقاز را در یک بازی ژئوپلتیکی انرژی قرار داده است. با در نظر گرفتن این منابع هیدروکربنی، این منطقه به یک میدانجنگ و رقابت تجاری برای بازی های ژئوپلتیکی قدرت های بزرگ جهانی تبدیل شده است. روسیه منطقه را به عنوان حیات خلوت خود تلقی نموده و علاقمند به حفظ حضورش می باشد تا همانند گذشته گاز طبیعی را به وسیله خط لوله مرکزی دریافت و به عنوان یک واس...
15 صفحه اولRelationships between land use , spatial scale and stream macroinvertebrate communities
1. The structure of lotic macroinvertebrate communities may be strongly influenced by land-use practices within catchments. However, the relative magnitude of influence on the benthos may depend upon the spatial arrangement of different land uses in the catchment. 2. We examined the influence of land-cover patterns on in-stream physico-chemical features and macroinvertebrate assemblages in nine...
متن کاملStream Macroinvertebrate Communities in Paired Hemlock and Deciduous Watersheds
Tsuga canadensis (Eastern Hemlock) is a common forest species that is declining throughout its range in the eastern United States because of the invasion of an exotic forest pest, Adelges tsugae (Hemlock Woolly Adelgid). This pest kills infected trees, and over time, infected stands are replaced by deciduous forests. The conversion of forests from hemlock to deciduous species is predicted to im...
