Assessing the Health Impacts of Contaminants on Green Turtles (Chelonia mydas) Along the Southern Coast of Brazil

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Chemical pollutants pose a significant threat to marine ecosystems. Among these contaminants are trace elements and polycyclic aromatic hydrocarbons (PAH). Green turtles can be employed to evaluate the oceans' health due to their coastal habitats and exposure to multiple threats.

Diatom Diversity on the Skin of Frozen Historic Loggerhead Sea Turtle Specimens

open access: yesDiversity, 2020
In recent years, biofilm-forming diatoms have received increased attention as sea turtle epibionts. However, most of the research has focused on carapace-associated taxa and communities, while less is known about diatoms growing on sea turtle skin.

A Guide to Nesting Sea Turtles in Florida

open access: yesEDIS, 2021
Florida’s coastline provides critical habitat for sea turtle nesting, as it has for millions of years. Throughout the state, three of the seven species of sea turtles in the world have significant nesting populations.

Male production in green sea turtles under a feminizing climate: A validated model of sex ratios with temperature‐dependent sex determination

open access: yesJournal of Animal Ecology, EarlyView.
This study introduces validated methods to predict sex ratios in wild Green sea turtle (Chelonia mydas) nests. It quantifies beach‐scale temperature heterogeneity, incorporates clutch‐level variation in thermal sensitivity and models temperature effects across the thermosensitive period, demonstrating how temporal temperature dynamics and spatial ...

Measuring energy expenditure in sub-adult and hatchling sea turtles via accelerometry.

open access: yesPLoS ONE, 2011
Measuring the metabolic of sea turtles is fundamental to understanding their ecology yet the presently available methods are limited. Accelerometry is a relatively new technique for estimating metabolic rate that has shown promise with a number of ...

Evaluation of a portable glucometer for blood glucose measurement in juvenile green sea turtles (Chelonia mydas)

open access: yesAustralian Veterinary Journal, EarlyView.
Blood glucose is a key physiological indicator in sea turtles, but its measurement in field settings can be challenging. Portable point‐of‐care (POC) glucometers offer practicality, yet their agreement with reference laboratory methods has not been established for juvenile green sea turtles (Chelonia mydas) from the Southwestern Atlantic.

Overview of the population genetics and connectivity of sea turtles in the East Asia Region and their conservation implications

open access: yesFrontiers in Marine Science
Understanding the current status and recent development of the population genetics and connectivity of sea turtles is crucial for effective conservation management of the species. Five sea turtle species, green turtle (Chelonia mydas), loggerhead turtle (

Complexity and variation in loggerhead sea turtle life history [PDF]

open access: yesBiology Letters, 2007
Juvenile loggerhead sea turtles spend more than a decade in the open ocean before returning to neritic waters to mature and reproduce. It has been assumed that this transition from an oceanic to neritic existence is a discrete ontogenetic niche shift. We tested this hypothesis by tracking the movements of large juveniles collected in a neritic foraging

Comparative species distribution model framework for marine conservation and its application to loggerhead turtles in the Mediterranean

open access: yesConservation Biology, EarlyView.
Abstract Modeling species distributions in dynamic pelagic environments remains challenging, particularly for wide‐ranging and highly mobile species when there is limited guidance on model performance. This limitation constrains the effective use of species distribution models (SDMs) in marine conservation, where robust and transferable predictions are
