Long-Term Monitoring of In-Water Abundance of Juvenile Pelagic Loggerhead Sea Turtles (Caretta caretta): Population Trends in Relation to North Atlantic Oscillation and Nesting

Frontiers in Marine Science, 2022
Sea turtles have various life-stages, typically being oceanic foragers as juveniles while shifting to more coastal habitats as they mature. The present study focuses on the least studied and well known of these, the juvenile oceanic life stage for the ...

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

Environmental 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.

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

PLoS 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 ...

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

Journal 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 ...

Loggerhead sea turtle bycatch data in artisanal fisheries within a marine protected area: fishermen surveys versus scientific observations

Animal Biodiversity and Conservation, 2011
Loggerhead sea turtles can be incidentally captured by artisanal gears but information about the impact of this fishing is inconsistent and scarce. Recent studies have observed that the bycatch, or incidental catch rate, in fishermen surveys is irregular.

Forty years of monitoring increasing sea turtle relative abundance in the Gulf of Mexico

Scientific Reports, 2023
Longitudinal data sets for population abundance are essential for studies of imperiled organisms with long life spans or migratory movements, such as marine turtles.

Do costal erosion and urban development threat loggerhead sea turtle nesting? Implications for sandy beach management

Frontiers in Marine Science, 2023
Nest beach selection by sea turtles at a regional scale may depend on upper shore environmental cues. Thus, the variability of sandy beach conditions, including coastal erosion rates and urban development can affect their nesting ecology.

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

Australian 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.

Tropical vs. temperate sea turtle population resilience to extreme temperatures

Ecological Indicators
Rising temperatures due to global warming over the last decades pose threats to marine biodiversity. Sea turtles are ectothermic species, and their embryonic development depends on nest conditions, particularly temperature.

Meiofauna Life on Loggerhead Sea Turtles-Diversely Structured Abundance and Biodiversity Hotspots That Challenge the Meiofauna Paradox

Diversity, 2020
Sea turtles migrate thousands of miles annually between foraging and breeding areas, carrying dozens of epibiont species with them on their journeys. Most sea turtle epibiont studies have focused on large-sized organisms, those visible to the naked eye ...
