Aggression 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 کاملThe population structure of two sympatric hermit-crab species on a subtidal rocky shore of an island in southeastern Brazil.
The main goal of this investigation was to characterize the population structure and shell occupancy of two sympatric hermit-crab species, Pagurus brevidactylus and Paguristes tortugae. The study was undertaken at Couves Island on the southeastern coast of Brazil, from March 2010 through February 2011, on subtidal rocky bottoms. Specimens were collected by SCUBA diving sessions. A total of 195 ...
متن کاملیافته علمی کوتاه: شناسایی خرچنگ منزوی libanarius signatus در جزیره هرمز؛ فراوانی، نسبت جنسی و عادت صدف‌گزینی این گونه
In order to establish a complete list of the hermit crab species in the southern coast of Iran and also determine some of their biological characteristics in the intertidal zones of Hormuz Island, a seasonal sampling collection was conducted in 6 intertidal stations during the years 2010–2011. The 542 collected samples were found to be Clibanarius signatus, which identified in the island. C...
متن کاملShell Selection in the Hermit Crab Clibanarius signatus Heller, 1861 from the Larak Island in the Persian Gulf
Shell selection indices of the dominant hermit crab Clibanarius signatus Heller, 1861, in the Larak Island were studied from September 2011 to June 2012. Among 739 sampled specimens, 41 different gastropod shell types were selected as shelters based on their abundance and local availability. A significant positive correlation (P<0/01) was found between the dimensions of the hermit crab, Cli...
متن کاملPopulation structure and reproduction of three sympatric species of hermit crabs in the north-western Mediterranean
The populations of three sympatric hermit crabs, Pagurus excavatus, Anapagurus alboranensis and Anapagurus petiti were studied in a shallow (15^25m) sandy area in the north-western Mediterranean. Seasonal abundance, seasonal size frequency, sex ratio and reproductive periods were examined. Pagurus excavatuswas the largest and most abundant species in the zone. Pagarus excavatus and Anapagarus a...
