Abstract Dive studies across mammals, birds, reptiles and fish often focus on deep dives, shallow water diving has tended to be overlooked. For air-breathers, foraging in poses challenges since the lungs generate buoyancy, divers must trade off extent of inhalation against negative buoyancy needed avoid floating surface. Using high-resolution depth loggers, we addressed this knowledge gap aroun...

Abstract Changes in marine ecosystems from human stressors, and concerns over how species will respond to these changes have emphasized the importance of understanding monitoring crucial demographic parameters for population models. Long-lived, migratory, vertebrates such as sea turtles are particularly vulnerable changes. Life-history like growth-in-body size can be largely influenced by envir...

Hawksbill turtles are considered Critically Endangered. An understanding of how nest microenvironment (moisture and temperature) maternal characteristics can influence embryonic development, hatching success, phenotype, hatchling performance is needed to ensure effective conservation management. We undertook controlled egg incubations at different temperatures relative humidities. Additionally,...

– Surveys of hawksbill turtles in the Atlantic Ocean have been undertaken to examine mitochondrial DNA (mtDNA) diversity and to test hypotheses concerning female reproductive migratory behavior and the composition of foraging ground populations. Studies of nesting females indicate that a natal homing mechanism predominates and that nesting populations should be considered separate stocks. Analy...

Hawksbill sea turtles Eretmochelys imbricata are found extensively around the world, including the Atlantic, Pacific, and Indian Oceans; the Persian Gulf, and the Red and Mediterranean Seas. Populations of this species are affected by international trafficking of their shields, meat, and eggs, making it a critically endangered animal. We determined the haplotypes of 17 hawksbill foraging turtle...

High seas oceanic ecosystems are considered important habitat for juvenile sea turtles, yet much remains cryptic about this important life-history period. Recent progress on climate and fishery impacts in these so-called lost years is promising, but the developmental biogeography of hawksbill sea turtles (Eretmochelys imbricata) has not been widely described in the Pacific Ocean. This knowledge...
