Habitat fidelity in hawksbill sea turtles

Ecology
Abstract Climate change is altering habitat suitability and driving shifts in species distributions. To understand potential responses by mobile animals, it is essential to assess levels of plasticity in habitat use, ranging from transience to long‐term fidelity.

Camera Traps: A Novel Method to Estimate Numbers of Nesting Sea Turtles. [PDF]

Ecol Evol
We compared sea turtle track counts from camera traps with those from simultaneous foot patrol surveys. Our findings support the use of camera traps as a complementary tool to fill data gaps at remote sites that would otherwise receive little to no assessment.

Somatic Growth Rates of Juvenile Green Sea Turtles (<i>Chelonia mydas</i>) in the Fijian Archipelago. [PDF]

Ecol Evol
We measured somatic growth rates of 215 juvenile green turtles across three foraging sites in the Fijian Archipelago from 2015 to 2022, finding a mean growth rate of 1.6 ± 0.1 cm year−1 that declined non‐monotonically with size and varied spatially between sites.

A brighter future? Stable and growing sea turtle populations in the Republic of Maldives.

PLoS ONE, 2023
The Indian Ocean represents a significant data gap in the evaluation of sea turtle population status and trends. Like many small island states, the Republic of Maldives has limited baseline data, capacity and resources to gather information on sea turtle

Local Adaptation May Help Mitigate Feminisation of Sea Turtle Populations Globally. [PDF]

Glob Chang Biol
We evaluate whether sea turtles have the capacity to adapt to warming temperatures through local adaptations of the pivotal temperature at which they produce a balanced amount of male and female hatchlings. We show that at warmer sites, lower proportions of female hatchlings are produced than expected.

Green and hawksbill turtle detection and abundance at foraging grounds in Bonaire, Caribbean Netherlands

Endangered Species Research, 2023
Abundance estimates corrected for changes in detection are needed to assess population trends. We used transect-count surveys and N-mixture models to estimate green turtle Chelonia mydas and hawksbill turtle Eretmochelys imbricata detection and total ...

Forensic characterization of sea turtle oil by ambient ionization mass spectrometry: Caretta caretta, Chelonia mydas, Dermochelys coriacea, Eretmochelys imbricata, Lepidochelys kempii, and Lepidochelys olivacea

Forensic Science International: Animals and Environments, 2021
Historically the oils from sea turtles have had a high commercial demand, and this trade has contributed to an alarming decrease in sea turtle populations worldwide.

The developmental biogeography of hawksbill sea turtles in the North Pacific [PDF]

Ecology and Evolution, 2016
AbstractHigh 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 ...

Insights into the successful breeding of Hawksbill sea turtles (Eretmochelys imbricata) from a long-term captive breeding program

Global Ecology and Conservation, 2020
Sea turtle populations are declining and evidence-based methods for supporting their populations are required. Captive breeding and release programs can be effective, offering the opportunity to supplement nature populations; however, sea turtles require
