Land 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 کاملEffects of Predation, Competition, and Isolation on the Rate of Shell Selection in the Hermit Crab Pagurus Longicarpus
S 81 increased population size of both species and expansion of the boreal forest, a likely result of global climate change, have caused areas of geographic overlap to occur. The Trumpeter and Tundra Swans are known to be reproductively compatible, as a viable hybrid population exists in Virginia at the Airlie Center’s Swan Research Program (SRP). Further, accounts from local wildlife managers ...
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...
متن کاملEffects of shell fit on the biology of the hermit crab Pagurus longicarpus (Say)
Most hermit crabs have a specialized lifestyle that requires them to occupy gastropod shells. The size of shells that hermit crabs inhabit relative to their body size affects their growth, survival and fecundity. In this study, the effects of shell fit on individual growth rate, risk of predation, feeding rate, and activity level were examined in the laboratory for hermit crabs Pagurus longicar...
متن کاملAggression and Food Resource Competition between Sympatric Hermit Crab Species
The vertical zonation patterns of intertidal organisms have been topics of interest to marine ecologists for many years, with interspecific food competition being implicated as a contributing factor to intertidal community organization. In this study, we used behavioral bioassays to examine the potential roles that interspecific aggression and food competition have on the structuring of interti...
