early triassic carbonate ramp sediments of the lower part of the elika formation are known as vermicular limestone. in the moro mountain, northwest iran, the vermicular limestone includes bioturbated dolomitic mudstone, bioclastic packstone and grainstone, algal calcirudite and intraclastic grainstone. these sediments accumulated in their lower part in open marine subtidal and shoal environment...

Rocky shores are one of the most important habitats of marine environment in coastal areas. This study was done in 2010-2011 to investigate the diversity of true crabs in intertidal rocky shores of Qeshm island. Samples were collected from intertidal zones during the low-tide at 5 stations. The specimens were fixed in 70% Etanol and transferred to laboratory for identification. Altogether, 15 c...

Foraminiferal assemblages have been collected from ten intertidal study areas situated on the east, south and west coasts of the UK. The assemblages display a vertical zonation which indicates that the distribution of foraminifera in these intertidal environments is usually the direct function of altitude with the duration and frequency of intertidal exposure the most important factors. Multiva...

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 species T. ...

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...

The frequency of marine sponges that harbour photosynthetic organisms was examined in a tropical area of the Western Indian Ocean. Out of 77 species from five different habitats in Zanzibar, 55 (71.5%) were found to have photosynthetic activity, as assayed by in situ pulse amplitude modulated (PAM) fluorometry (and validated by measurements of chlorophyll content). A significantly higher percen...

Intertidal sediment distribution is an important factor in the understanding of estuarine ecological, morphological and pollution processes.Airborne remote sensing is identiŽ ed as a cost-eŒective tool that may be used to provide accurate synoptic maps of estuarine sediment distributions.However, prior to the collection and analysis of airborne imagery, spectral characterization of intertidal s...

Biodiversity and community structure of macrofauna of the intertidal sandy beach at Chabahar Bay were studied for a period of ten months in 2007. A total of 32 species were observed and identified in this study so that polychaete with 16 species was numerically dominant. The results showed changing densities were influenced by monsoon season so that maximum density (1935.47 ind/m2) was observed...
