TL;DR: In this paper , the authors looked at the possible effects on fitness and primary sex ratio for the olive ridley sea turtle (Lepidochelys olivacea) when nesting during peak and low nesting seasons, and found that eggs incubated during the dry low season were exposed to lower temperatures, yielded higher hatchling success, mainly produced male offspring and larger, heavier hatchlings with better locomotor abilities.

Mitigating the effects of climate change on the nests of sea turtles with artificial irrigation
TL;DR: In this article , the authors reviewed the literature on nest irrigation to examine whether artificial irrigation is feasible as a population management tool, and found that the number of water applied and the frequency of applications were important factors for cooling sea turtles.

How will changes in local climate affect hawksbill hatchling production in Brazil
Natalie Montero,Marcovaldi MAd,Lopez–Mendilaharsu M,Alexsandro Santana dos Santos,Santos Ajb,Mariana M. P. B. Fuentes +5 more
TL;DR: Hatching success of undisturbed nests (no recorded depredation or storm-related impacts) will decrease in Brazil by 2100 and the determining effects of different climate variables and their combinations on an important and critically endangered marine species are shown.
Journal ArticleDOI
Direct and indirect pathways for environmental drivers of hatching success in the loggerhead sea turtle
TL;DR: In this article , the authors studied the effects of nest site selection on hatching success by linking nest placement characteristics to hatch success through a structural equation model and found that nests placed at the highest elevations had the highest success rates, likely because those nests had a much lower chance of being washed over by high tides and higher mean temperatures.

Thermal conditions of green turtle, Chelonia mydas, nests in the largest rookery in the eastern Mediterranean
TL;DR: In this article , the mean temperature of the nests ranged from 28.4 to 33.5°C and those experiencing high temperatures exhibited low hatching success, while metabolic heating was highest in the last third of the incubation duration, and was significantly correlated to clutch size.

TL;DR: A large increase was seen in the number and proportion of hurricanes reaching categories 4 and 5 and the number of cyclones and cyclone days has decreased in all basins except the North Atlantic during the past decade.

The Recent Increase in Atlantic Hurricane Activity: Causes and Implications
TL;DR: The years 1995 to 2000 experienced the highest level of North Atlantic hurricane activity in the reliable record, and the present high level of hurricane activity is likely to persist for an additional ∼10 to 40 years.

Sex Determination in Reptiles
TL;DR: Temperature-dependent sex determination (TSD) is common in turtles and has been reported in two lizards and alligators; however, data on TSD are available for few non-turtle species and an attempt is made to deduce their ancestries.

Climate change and marine turtles
TL;DR: This article reviewed the data from peer-reviewed publications to assess the likely impacts of climate change on marine turtles and highlight the types of data that would be most useful for an accurate assessment of future effects.
