The present study was conducted to investigate the effects of cyclone Gonu on species diversity and abundance of gastropods in the Qeshm Island, northern Persian Gulf, on the occasion of the occurrence of super cyclonic and strongest reported storm- Gonu- during 1-4, June 2007 in the eastern Arabian Sea. Samples were collected before the Gonu storm (late May and early June 2007) and twice ...

Stratospheric ozone depletion and the concomitant increase in irradiance of ultraviolet-B radiation (UVB) at the earth’s surface represent major threats to terrestrial and aquatic ecosystems. In costal rocky shore environments, seaweeds constitute a group of organisms of particular significance to ecosystem function. Thus, impairment of seaweed performance by UVB-exposure may result in severe c...

A new species of pagurapseudid, Macrolabrum maui, is described from the lower eulittoral rocky shore on the East Coast of the North Island, New Zealand. It is similar to M. haikung from Bass Strait, Australia and M. distonyx from New Caledonia. Males and females show little dimorphism. Typical of the subfamily Pagurapseudinae, M. maui inhabits shells of micro-molluscs such as the gastropods Eat...

The Larsemann Hills (69°24'5, 76°20'E), situated on the Ingrid Christensen Coast of Princess Elizabeth Land, Antarctica, consist of a series oflow-Iying, rocky peninsulas and islands on the southern shore of Prydz Bay. This area (fig. 1), which extends over 200 km2, is ice-free during the summer and bestrewn with more than 150 freshwater lakes. In the 1990/91 and 1991192 austral summers, the op...

Shore platform erosion is considered a driving mechanism for cliff recession on many rocky coasts and, in the vicinity of sea defence structures, a threat to their stability, yet the spatial pattern of platform erosion, as well as the rate of lowering, is poorly documented. Measurements based on techniques such as the micro-erosion metre or laser scanner, though highly accurate for short time s...

Predicting the impacts of ocean acidification on coastal ecosystems requires an understanding of the effects on macroalgae and their grazers, as these underpin the ecology of rocky shores. Whilst calcified coralline algae (Rhodophyta) appear to be especially vulnerable to ocean acidification, there is a lack of information concerning calcified brown algae (Phaeophyta), which are not obligate ca...

Journal of Coastal Research, 24(1A), 244–249. West Palm Beach (Florida), ISSN 0749-0208. At 23 sites selected randomly around the island of São Miguel (Azores), video records were made at the depths of 5, 10, 15, 20, 25, and 30 m where a roc...
