Sea turtle epibionts can provide insights into the hosts' habitat use. However, at present, there is a lack of information on sea epibiont communities in many locations worldwide. Here, we describe 46 hawksbill turtles ( Eretmochelys imbricata ) Persian Gulf. Specifically, sampled 28 from Dayyer-Nakhiloo National Park (DNNP) northern Gulf and 18 Shibderaz beach Strait Hormuz. A total 54 macro, ...

Due to progressive urban development along the Mexican Caribbean coastline, it is crucial gauge impact of anthropogenic contamination marine ecosystems through biomonitoring procedures. In current study, we quantified concentration 49 inorganic elements in blood and scute tissues clinically healthy nesting hawksbill sea turtles (Eretmochelys imbricata). The were classified into four groups: Gro...

Female sea turtles have rarely been observed foraging during the nesting season. This suggests that prior to their migration to nesting beaches the females must store sufficient energy and nutrients at their foraging grounds and must be physiologically capable of undergoing months without feeding. Leptin (an appetite-suppressing protein) and ghrelin (a hunger-stimulating peptide) affect body we...

Nesting by hawksbill sea turtles Eretmochelys imbricata in Barbados, West Indies, has been monitored since 1992. Data from the index beach indicate that the number of nests may have increased as much as 8-fold over this period. The estimated abundance of nesting females on Barbados is 1250, suggesting that this eastern Caribbean island now hosts one of the largest rookeries in the wider Caribbe...

The hawksbill turtle is an ectotherm, whose sex is determined by temperature during embryonic development. This study aimed to determine whether embryonic hawksbill turtle cells respond differently to temperature than mammalian cells. Embryonic hawksbill turtle cells were established in culture, and thermal effects on these cells were investigated in vitro. Cells were maintained in Dulbecco's M...

Host-specificity tests were conducted involving two provenances of D. tomentosus: one collected from C. imbricata in South Africa (henceforth called the imbricata provenance) and one collected from C. rosea in Mexico (henceforth called the rosea provenance). These provenances were reared on both C. imbricata and the target weed, Cff. On the target weed, the imbricata provenance survived poorly ...
