Macrobenthos abundance and distribution on a spatially patterned intertidal flat
Natural ecosystems can show regular spatial vegetation patterns, which develop from small-scale ecological interactions. Some studies suggest that grazers can play a major role in controlling vegetation distribution in ecosystems with regular vegetation patterns, but the distribution of grazers and the effects of grazing on vegetation in spatially patterned ecosystems remains poorly understood....
متن کاملChanges in diatom patch-size distribution and degradation in a spatially self-organized intertidal mudflat ecosystem.
Self-organized spatial patterns have been proposed as possible indicators for regime shifts in ecosystems. Until now, this hypothesis has only been tested in drylands. Here, we focus on intertidal mudflats where regular spatial patterns develop in early spring from the interaction between diatom growth and sedimentation but disappear when benthic herbivore abundance increases in early summer, a...

چکیده این مطالعه با هدف بررسی الگوی پراکنش و تعیین فراوانی فصلی و زیستگاهی خرچنگهای منزوی در شش ایستگاه واقع در ناحیه جزر و مدی جزیره هرمز انجام پذیرفت. نمونهبرداری در یک دوره یک ساله و در چهار فصل انجام شد. خرچنگ منزوی در اتانول 70 % تثبیت و به آزمایشگاه منتقل شدند. با استفاده از کلیدهای شناسایی معتبر 9 گونه متعلق به دو خانواده از خرچنگهای منزوی مورد شناسایی قرار گرفت. آنالیزهای آماری با است...
متن کاملPredicate Logic Processor of Spatially Patterned Signals
A processor is proposed for spatially modulated or patterned signals. Two voltage impulses are transmitted along the coupled wires and they are considered as a predicate expression. The developed gates and processor perform the predicate logical operations AND, NOT and OR with these expressions. The designed processor is applicable to the artificial intelligence area especially it will be usefu...
