In the North Sea, during autumn-winter, intertidal flats often receive a massive influx of migratory shorebirds (wildfowl, waders and seabirds), which utilise the high prey densities that are available. The present study was conducted at Culbin Sands lagoon, NE Scotland, in 1994-1996, to investigate benthic invertebrate standing stock, and the ener...

Population outbreaks of the starfish Acanthaster planci have been persisting for at least the past 25 yr on coral reefs in the Gulf of Oman, in the northwestern Indian Ocean. A survey conducted in 2001 showed that the A. planci population on the Dimaniyat Is. was as abundant (around 5 individual (ind.)/transect; equivalent to 100 ind./ha) as that r...

Green turtles Chelonia mydas nest year round at the Ras Al Hadd Nature Reserve, Oman, with a distinct lower-density nesting season from Oct. to May, and a higher-density nesting season from June to Sept. On these beaches, the main predators of turtle eggs and hatchlings are foxes Vulpes spp., wolves Canis lupus arabs, and wild cats Felis spp. and C...

Based on filtration rates obtained in situ at several habitats (mud flats, sand flats, and seagrass beds of Cymodocea nodosa), particle retention efficiency of benthic communities was estimated at Ria Formosa, a coastal lagoon in southern Portugal. The distinct physical characteristics of the water flow (water depth, current speed) at different tid...

The seaturtle population of loggerheads Caretta caretta nesting on Masirah Island, Arabian Sea, has been known since the 1970s as the largest population worldwide, with at least 30,000 annual nesting females. These numbers have been again confirmed by studies conducted in the mid 1980s. During the 1990s, the population was monitored less intensivel...

Epibenthic communities and their diets, at Culbin Sands (a cold-temperate coastal lagoon in the Moray Firth, northeastern Scotland), were sampled every 2-4 wks for 3 yrs (1994-1996). These communities were more abundant and diverse in warmer months, especially in less-exposed areas of the lagoon. The most common species were the brown shrimp Crango...

In the present study, Culbin Sands lagoon, a protected site in NE Scotland, was surveyed every 2 to 4 weeks during a three-year period (1994-1996) to study benthic invertebrate communities. Beds of Mytilus edulis covered 18000 m2. 53 macroinfaunal species were identified outside these areas. The most conspicuous were: the lugworm Arenicola marina (...

The waters off the Sultanate of Oman are the gateway to the oil-rich region of the Arabian Gulf. Therefore, traffic of petroleum tankers is intense, and oil spills occur from time to time. In addition to that, the products of the oil exploitation sometimes are also released into the marine environment, despite tough legislation and law enforcement...

The green turtle, Chelonia mydas, nesting population of Ras Al Hadd, Arabian Sea, is the largest in the Indian Ocean (13,000 - 20,000 ind. nesting annually). The area has a busy maritime traffic connecting the Indian Ocean to the Arabian Gulf, and is one of the most oil-polluted areas of the world. In this study, conducted in 2003, trace metal conc...

The Culbin Sands lagoon ecosystem in NE Scotland was studied during a three-year period (1994-1996) to identify the major trophic links from benthic invertebrates to epibenthic predators, and to assess impacts of overwintering fish on their prey communities. Every 2-4 weeks, samples of mobile fauna were collected to study their diets. The major tro...

Four sea species nest on Oman beaches. These are the loggerhead Caretta caretta population on Masirah Island in the Arabian Sea, the green turtle Chelonia mydas at Ras Al Hadd Nature Reserve in the Arabian Sea, and the hawksbill turtle Eretmochelys imbricata on Al Dimaniyat Islands Nature Reserve in the Gulf of Oman are of global importance.

The Al Hallaniyat Islands in the Arabian Sea are under the influence of a seasonal monsoon from June to August-September, which enhances high algal and seagrass productivity, providing good feeding grounds for marine turtles. This archipelago consists of four islands: Al Hasikiyat, As Sawda, Al Hallaniyat and Al Qibliyat. The only previous availab...

The Dimaniyat Islands in the Gulf of Oman, an archipelago of nine uninhabited islands, surrounded by coral reefs, provide good feeding and nesting grounds for hawksbill turtles Eretmochelys imbricata. This is probably the densest population of hawksbill on earth for this species, with at least 250 females per year nesting on 1.5 Km of beaches (Salm...

The Sultanate of Oman is among the Indian Ocean nations with the largest nesting populations of green turtles Chelonia mydas and loggerhead turtles Caretta caretta. These two turtle species have been recorded to nest in high numbers in the Dhofar Region (Ross and Barwani, 1981; Salm, 1991), in southern Oman, on the Arabian Sea shores. Hino Island i...

The giant tortoise Geochelone sulcata presently occurs mainly in areas surrounding the Sahara desert and in small pockets throughout the African continent.

In the Sultanate of Oman, data from the late 1990s showed total discharges to the sea by treated effluents from Sewage Treatment Plants (STPs) of 250,000 m3/day, equivalent to 91,250 x 10 3 m3/year from 8 STPs. Data for the year 2003 show much lower discharges (38,705 m3/day, equivalent to 14,127x 10 3 m3/year from 267 STPs). This was due to a wise...

EXTENDED ABSTRACT: Hawksbill turtles Eretmochelys imbricata are considered critically endangered species (Groombridge, 1982; Groombridge and Luxemore, 1989; Meylan and Donnelly, 1999). Therefore, knowledge concerning the status and ecology of the remaining populations is of vital importance for their conservation. Coral reef areas like the Dimaniy...

ABSTRACT: The Dimaniyat Islands in the Gulf of Oman, an archipelago of nine uninhabited islands surrounded by coral reefs, provide good feeding and nesting grounds for hawksbill turtles Eretmochelys imbricata. During the nesting seasons of 1999 and 2000, extensive surveys of the Dimaniyat Islands permitted a better understanding of this turtle popu...

ABSTRACT: The coastal line of the Dhofar Region is about 400 km long, with sandy beaches intercalated by rocky shore. Some sandy beaches are several kilometres long, and human disturbance is limited to artisanal fishery activities. On the other hand, the seasonal monsoon makes these waters very rich in biodiversity. Therefore, the region provides g...
