Expression of human mutant cyclin dependent kinase 4, Cyclin D and telomerase extends the life span but does not immortalize fibroblasts derived from loggerhead sea turtle (Caretta caretta) [PDF]

, 2018
Conservation of the genetic resources of endangered animals is crucial for future generations. The loggerhead sea turtle (Caretta caretta) is a critically endangered species, because of human hunting, hybridisation with other sea turtle species, and ...

A Guide to Nesting Sea Turtles in Florida

EDIS, 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.

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.

Observer coverage and interaction rates determine the choice between design‐based and machine learning bycatch estimators for rare species

Conservation Biology, EarlyView.
Abstract Robust estimates of the magnitude of protected species bycatch are essential for effective fisheries management and marine conservation. Existing bycatch estimation methods typically struggle to accurately and precisely estimate the bycatch of rare species as a result of the statistical assumptions necessary to overcome infrequent encounters ...

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.

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 ...

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 ...

An update on hatchery success of olive ridley turtles (Lepidochelys olivacea) at Playa San Miguel, Costa Rica

Conservation Science and Practice, EarlyView.
This study aims to elucidate and update the impacts of nest temperatures and rainfall on the San Miguel olive ridley hatchery success from 2019 to 2022 sea turtle seasons. Nest sand temperatures significantly affect nest failures (Estimate = 0.123 ± 0.059 SE, z = 2.088, p = .037) while nesting seasons also significantly affect nest failures with lower ...

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 ...

Boldness Predicts Nest‐Site Choice of a Freshwater Turtle in an Anthropogenically Disturbed Landscape

Ethology, EarlyView.
One measure of antipredator behavioral boldness predicted turtle nest distance to the nearest human‐made structure. Turtles experienced two behavioral assays to quantify boldness (left panel). Turtles that displayed more bold behaviors during simulated predation nested closer to human‐made structures (top right) than their shyer counterparts (bottom ...
