Patterns of Weight Gain and Birth Weight Amongst Indian Women
Background: The timing of maternal weight change in pregnancy may be an important determinant of birth weight. The objective of this study was to measure weight gain patterns from early pregnancy until delivery, and to examine the relationship between prenatal weight gain and low birth weight. Methods: A total of 500 pregnant women within 15-20 days of conception, with confirmed pregnancies and...
متن کاملLand hermit crab (Coenobita clypeatus) densities and patterns of gastropod shell use on small Bahamian islands
Land hermit crabs are common in many insular and coastal habitats in tropical and subtropical regions worldwide (Hartnoll, 1988; Greenaway, 2003). Some species, such as Coenobita clypeatus (Herbst), may be found many kilometres inland (Chace & Hobbs, 1969; DeWilde, 1973; NievesRivera & Williams, 2003). However, relatively few studies have addressed the densities of land hermit crabs, their ecol...
متن کاملShell Exchange in Hawaiian Hermit Crabs
Shell exchange behavior of intertidal Hawaiian hermit crabs was observed in the laboratory. Outcomes of 255 shell-related interactions were analyzed to test the predictive powers of two models of resource exchange . In the case of intraspecific interactions, the negotiations model (which predicts that exchanges should occur only when both crabs will gain in shell value) was superior to an aggre...
متن کاملdistribution pattern and seasonal and spatial abundance of hermit crabs (crustacean: paguroidea) in the intertidal zones of hormuz island
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 کاملRelationships between a hermit crab and its shell resource: spatial patterns within a seagrass- dominated landscape
Abundance patterns of the hermit crab Pagurus maclaughlinae and its gastropod shell resources were compared to one another across the shallow subtidal landscape within Tampa Bay, Florida at a landscape (4.88 ha) and a sub-landscape (1 m2) scale. Specifically, we investigated whether the spatial abundance patterns of P. maclaughlinae over time could be explained by the abundance patterns of eith...
