Is the Japanese skeleton shrimp Caprella mutica a filter feeder? I. Head morphology and kinematics
An active filter feeding organism strains suspended matter from the surrounding water using a sieving structure. Small marine filter feeders however, have to cope with the physical problems of the high viscosity as indicated by the low Reynolds number. In a highly viscous regime, organisms' appendages are surrounded by a thick boundary layer, which makes movement and filter feeding difficult. I...
متن کاملMitochondrial DNA reveals multiple Northern Hemisphere introductions of Caprella mutica (Crustacea, Amphipoda).
Caprella mutica (Crustacea, Amphipoda) has been widely introduced to non-native regions in the last 40 years. Its native habitat is sub-boreal northeast Asia, but in the Northern Hemisphere, it is now found on both coasts of North America, and North Atlantic coastlines of Europe. Direct sequencing of mitochondrial DNA (cytochrome c oxidase subunit I gene) was used to compare genetic variation i...

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 اولEffects of tributyltin exposure in the embryonic stage on sex ratio and survival rate in the caprellid amphipod Caprella danilevskii
In order to examine the biological effects of tributyltin (TBT) exposure, the caprellid amphipod Caprella danilevskii was exposed to 5 levels (0, 10, 100, 1000 and 10000 ng l–1) of TBT during the embryonic stage (5 d). The male and female ratios changed dramatically in the hatched juvenile with increases in TBT concentrations; i.e. the proportion of females was found to increase to 55.6% at 10 ...
متن کاملDescription of a widely distributed but overlooked amphipod species in the European Alps
Amphipods are keystone species in many freshwater ecosystems. Understanding their distribution and diversity is crucial to ensure and preserve freshwater ecosystem functioning, particularly in the northern hemisphere. For the European Alps information on amphipods has been relatively limited until recently. We describe a new, widely distributed amphipod species, Gammarus alpinus sp. nov., found...
