“…In agreement with Al Ameri et al, 9 Phillott et al, 10 and Mancini et al, 11,12 the studied areas in the Red Sea showed different pattern as they still keep their importance as nesting and foraging areas. The Zabargad Island is considered one of the most important nesting sites in Egypt and the Red Sea as well, where the estimated number of nests per year according to Mancini et al 12 ≈500 -600 nests.…”

In Egypt, along the Mediterranean coast, the loggerhead (Caretta caretta) and green (Chelonia mydas) come during nesting season to lay their eggs or for food with a rare occurrence for the leatherback turtle (Dermochelys coriacea). In the Egyptian Red Sea there are five species that come to visit, the most common to observe are hawksbill (Eretmochelys imbricata) and green (Chelonia mydas). The goal of this study is to conduct some genetic and ecological analyses a) to generate new markers that include other segments of marine turtles’ genome, as a tool to investigate new areas of variation/polymorphism between, among, and within populations and individuals; b) determine genetic diversity between and within the Mediterranean and the Red Sea populations using (individuals from the same and different habitats using ISSR); and c) determine allele frequency. At the ecological level, this study aims to assess sea turtles' habitat and population distribution among different habitats in Egypt. Throughout the duration of this study, it was noted that there was a decrease in nesting areas attributable to the loss and fragmentation of habitats. Although there are some areas with no significant nesting prosperities it considered significant areas for foraging and highly important as migratory corridors, especially in the Mediterranean. The massive urbanization and unplanned touristic developments affect sea turtle habitat over the Egyptian Mediterranean coast. The Mediterranean coast showed demographic changes in the coastal regions. On the other hand, areas could still be valued with significant nesting areas for sea turtles, but an intense and regular monitoring programme should be established. The Red Sea needs a regular monitoring programme for better management conservation measures to be adopted. The polymorphism percentage resulting from ISSR marker was 45 and 36 for both loggerhead and green turtle populations in the Mediterranean, respectively; and 69 for the green turtle populations in the Red Sea.

“…It is difficult to draw general conclusions, however, due to the small number of home ranges that have been measured among these studies. In-water studies, including on foraging ecology, are lacking in the Northwest Indian Ocean 50 . Consequently, it is unclear whether grazing habitats are being fragmented or degraded due to human activities in this region.…”

Sea turtles are migratory with nesting and foraging areas in distinct and often widely separated habitats. Telemetry has been a vital tool for tracking sea turtle migrations between these areas, but tagging efforts are often focused on only a few large rookeries in a given region. For instance, turtle tagging in the Red Sea has been focused in the north of the basin. We tagged five green turtles (Chelonia mydas) at a nesting site in the central-southern Red Sea and tracked them for 72–243 days. During the inter-nesting period, the turtles showed high site-fidelity, with a maximum home range of 161 km2. After the nesting season, the turtles migrated up to 1100 km to five distinct foraging locations in three countries (Saudi Arabia, Sudan, and Eritrea). Movements within foraging habitats were more wide-ranging compared to inter-nesting movements, with home ranges varying between 1.19 and 931 km2. The tracking data revealed that the creation of a relatively small marine reserve could protect the critical inter-nesting habitat in the Farasan Banks. The results also highlight the need for multinational collaboration to protect migratory corridors and foraging sites of this endangered species.

Within the waters of the United Arab Emirates (UAE), there are nine sea snake species and five species of sea turtles, two of which (Hawksbill and Green Sea Turtles) are breeding and forage residents and the remainder migrate to feed through UAE waters. Not only are the waters of the UAE recognized as important habitats for Hawksbill and Green Sea Turtles, but sea turtles are ambassador species for ocean conservation and recognized as a priority species by policy makers and conservationists alike. As a result, despite their numerous challenges, Hawksbill and Green turtle populations in the country are relatively stable. On the other hand, Loggerhead and Olive Ridley Sea Turtles, along with sea snakes enjoy far less interest and attention and so their threats, ecology and population status remain ambiguous. The known challenges facing marine reptiles in the UAE include, but are not limited to, habitat destruction through coastal development, marine pollution, bycatch and climate change.
