Lunar phases and hawksbill sea turtle nesting

Journal of Ethology, 2019
The behavior of sea turtle species can be influenced by the lunar cycle, possibly due to moonlight variability. We analyzed the relationship between nesting behavior and moon phase using nesting hawksbill turtle records for beaches in Northeast Brazil for the 2006–2007 to 2015–2016 seasons.

Hawksbill Sea Turtles in the Northwestern Hawaiian Islands

Chelonian Conservation and Biology, 2012
Abstract This study reports observations of Hawksbill sea turtles (Eretmochelys imbricata) in the Northwestern Hawaiian Islands, a remote and protected expanse of coral atolls considered outside the species range. Since no direct monitoring efforts exist, we synthesized records from historical accounts, opportunistic sightings, and internet ...

Dispersal, recruitment and migratory behaviour in a hawksbill sea turtle aggregation

Molecular Ecology, 2008
AbstractWe investigated the dispersal, recruitment and migratory behaviour of the hawksbill sea turtle (Eretmochelys imbricata), among different life‐history stages and demographic segments of the large hawksbill turtle aggregation at Mona Island, Puerto Rico.

Offshore Dispersal and Predation of Sea Turtle Hatchlings I: A Study of Hawksbill Turtles at Chagar Hutang Turtle Sanctuary, Malaysia

Ichthyology & Herpetology, 2021
Sea turtle hatchlings emerge from underground nests at night, rapidly crawling seaward to swim off shore. Once in the water, hatchlings might experience high predation rates while in shallow water before reaching deeper water where encounters with predators, and consequently mortality rates, likely decline.

Inter-Seasonal Maintenance of Individual Nest Site Preferences in Hawksbill Sea Turtles.

Ecology, 2006
Within a single population of hawksbill sea turtles (Eretmochelys imbricata), we found a behavioral polymorphism for maternal nest site choice with respect to beach microhabitat characteristics. Some females preferred to nest in littoral forest and in places with overstory vegetation cover, and others preferred to nest in more open, deforested areas ...

Pharmacokinetic characteristics of danofloxacin in green sea (Chelonia mydas) and hawksbill sea (Eretmochelys imbricata) turtles

Journal of Veterinary Pharmacology and Therapeutics, 2022
AbstractTo date, the number of green sea and hawksbill sea turtles is in decline due to environmental, anthropogenic, and pathological factors. The present study described the pharmacokinetic characteristics of danofloxacin (DNX) in green sea and hawksbill sea turtles, following single intravenous (i.v.) and intramuscular (i.m.) administrations at ...

Efficient Establishment of Primary Fibroblast Cultures From the Hawksbill Sea Turtle (Eretmochelys imbricata)

In Vitro Cellular and Developmental Biology - Animal, 2012
The hawksbill sea turtle (Eretmochelys imbricata) is a critically endangered species at a risk of extinction. Preservation of the genomic and cellular information of endangered animals is important for future genetic and biological studies. Here, we report the efficient establishment of primary fibroblast cultures from skin tissue of the hawksbill sea ...

Later Nesting by Hawksbill Turtle following Sea Surface Warming

Journal of Herpetology, 2020
We studied the nesting behavior of the Hawksbill Turtle (Eretmochelys imbricata) along the northeastern coast of Brazil, specifically in southern Rio Grande do Norte. We compare the peak of nesting activity for several seasons from 2006 to 2016. The raw data consist of daily records of the presence of hawksbill turtle on a beach (N = 3,717).

Hawksbill sea turtles in seagrass pastures: success in a peripheral habitat

Marine Biology, 2009
Hawksbill sea turtles, Eretmochelys imbricata, are closely associated with coral reef and other hard-bottom habitats. Seagrass pastures are peripheral habitats for Caribbean hawksbills. With the decline in quality and quantity of coral reefs, seagrass habitats may become more important for hawksbills.

Toxicological Assessment of Hawksbill Sea Turtle Eggs From the Arabian Gulf

Marine Pollution Bulletin
Hawksbill sea turtles (Ertemochelys imbricata) play a crucial role in maintaining reef health and have the potential to serve as key indicator species for monitoring environmental conditions. This study evaluates concentrations of polycyclic aromatic hydrocarbons (PAHs), and organochlorine pesticides (OCPs) in the eggs of hawksbill sea turtles (n = 28 ...
