Avoidance of drilled gastropod shells by the hermit crab Pagurus longicarpus at Nahant, Massachusetts.
Most hermit crabs depend on empty gastropod shells for shelter; competition for appropriate shells is often severe. This study determined whether shells that have been drilled by naticid gastropods are suitable for occupancy by the hermit crab Pagurus longicarpus. Differences in the characteristics of empty shells and those occupied by hermit crabs were assessed at two adjacent field sites in N...
متن کاملThe use of artificial shells for exploring shell preference in the marine hermit crab Pagurus longicarpus (Say)
Although recognition behavior is central to many aspects of an organism’s biology, it has been difficult to effectively identify the individual recognition components (i.e., production, perception, and action) for most organisms. Among hermit crabs, a relatively well-studied system for recognition behavior, the precise shell cues that stimulate crabs to explore and choose empty shells are uncle...
متن کاملFighting for shells: how private information about resource value changes hermit crab pre-fight displays and escalated fight behaviour.
Pre-fight displays typically provide honest, but sometimes dishonest, information about resource holding potential and may be influenced by assessment of resource value and hence motivation to acquire the resource. These assessments of potential costs and benefits are also predicted to influence escalated fight behaviour. This is examined in shell exchange contests of hermit crabs in which we e...
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...
متن کاملCrab biodiversity under different management schemes of mangrove ecosystems
Reforestation is one of the Philippines’ government efforts to restore and rehabilitate degraded mangrove ecosystems. Although there is recovery of the ecosystem in terms of vegetation, the recovery of closely-linked faunal species in terms of community structure is still understudied. This research investigates the community structure of mangrove crabs under two different management schemes: p...
