Crayfish: Northern crayfish Orconectes virilis Louisiana crayfish Procambarus clarkii Water nymph crayfish Orconectes nais Rusty crayfish Orconectes rusticus Utah is inhabited by a single native crayfish known as the Pilose crayfish Pacifastacus (Hobbsastacus) gambelii. Its native range is in northern Utah’s Bear River, Weber River and Ogden River drainages and in the Raft River Mountain’s drai...
متن کاملAssessing ecosystem vulnerability to invasive rusty crayfish (Orconectes rusticus).
Despite the widespread introduction of nonnative species and the heterogeneity of ecosystems in their sensitivity to ecological impacts, few studies have assessed ecosystem vulnerability to the entire invasion process, from arrival to establishment and impacts. Our study addresses this challenge by presenting a probabilistic, spatially explicit approach to predicting ecosystem vulnerability to ...

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
15 صفحه اولBehavioural and growth differences between experienced and naı̈ve populations of a native crayfish in the presence of invasive rusty crayfish
1. Species invasions are a leading threat to native species and ecosystems. How populations of native species respond to the presence of invasive species will ultimately determine their long-term persistence. 2. In this study, we capitalise on a unique opportunity to compare the behaviour and growth of naı̈ve and experienced virile crayfish (Orconectes virilis Hagen) populations in the presence ...

ing subject, combining engineering with economic, social, and political factors. Technology seems to advance in waves. Small advances in science and technology accumulate slowly, sometimes over long periods of time, until a critical level of technological success and economic advantage is achieved. The last century witnessed several of these waves: automobiles, radio, aircraft, television, and ...
