Mortality, behavior and the effects of predators on the intertidal distribution of littorinid gastropods.
Predators can affect the vertical distribution of mobile intertidal invertebrates in two ways: they can (1) cause greater mortality of prey at certain intertidal levels, and (2) induce prey to seek safer intertidal areas. In this study, we investigate whether low-intertidal and subtidal predators affect the intertidal distribution of two congeneric species of small herbivorous gastropods of nor...
متن کاملTemporal Variation in Rocky Intertidal Gastropods of the Qeshm Island in the Persian Gulf
Gastropod assemblages were investigated along intertidal rocky shore in the Qeshm Island in the northern Persian Gulf. Monthly sampling was undertaken from May 2007 to April 2008. Environmental factors were also measured in each site. A total of 28 gastropod taxa belonging to 15 families were identified and Cerithiidae was the most abundant family and Cerithium caeruleum was the most abundant...
متن کاملThe Heat-Shock Response: Its Variation, Regulation and Ecological Importance in Intertidal Gastropods (genus Tegula)1
SYNOPSIS. The enhanced synthesis of heat-shock proteins (hsps), called the heat-shock (or stress) response, is activated when environmental stress denatures proteins. Hsp synthesis is activated at the upper temperatures of an organism’s thermal range and is therefore thought to be critical for enhancing thermal tolerance limits in ectothermic animals. Here I show that the two temperate sister s...

متن کاملLarge-scale determinants of trematode infections in intertidal gastropods
The influence of latitude, substrate type, tidal level, and host shell size on trematode species-richness and prevalence were assessed using published data on 255 samples from 54 species of marine intertidal gastropods. The analyses were performed at different levels of statistical independence: among all samples, across snail species, and using phylogenetically independent contrasts. Repeatabi...
