Abstract Global trends in marine turtle nesting numbers vary by region, influenced environmental or anthropogenic factors. Our study investigates the potential role of past temperature fluctuations on these trends, particularly whether warmer beaches are linked to increased due higher female production (since sea turtles have temperature‐dependent sex determination). We selected loggerhead ( Caretta caretta ) its wide distribution, strong philopatry and vulnerability changes. compiled nest counts per year 35 globally significant rookeries, analysing at regional individual beach levels. air (CHELSA) land surface (MODIS) data sets spanning last four decades (1979–2023) for each location. To analyse temporal temperatures, we used generalised additive models Mann–Kendall trend tests. Additionally, correlated with lagged variables. found warming 33 locations, 23 which also showed increases counts. results suggest that rising temperatures may be boosting regions Caribbean, Atlantic Ocean Mediterranean (sites Cayman, Mexico, Brazil, Cyprus Turkey). Furthermore, while some temporarily benefit, continued could precipitate long‐term population declines. This variability helps predict species responses climate change, general global increase already indicating short‐term effects. Nesting count might reflect a combination natural ecological phenomena, conservation efforts, Long‐term studies needed assess ratio hatchlings extent feminisation is driving numbers.

Global Decline in the Size of Sea Turtles

ABSTRACT Changes in mean adult body size may be a universal response to global warming and sometimes lead conservation concerns. We show that reductions sea turtles are now the norm have another explanation. From 18,707 measurements of nester (curve carapace length) for spanning 30 years from Redang Island (Malaysia), where nearly all nesting individuals been tagged, we was initially fairly stable then decreased by 4.0 cm 100.8 2005 96.8 2022, which likely translates change mass 120 105 kg. At same time, increased around 300 2000 nests per year. Consistent with this finding reduction an expanding population, at 27 31 sites across globe changes assessed, is decreasing, most marked decreases population increasing dramatically. Taken together, these focal findings suggest important driver influx small first‐time nesters (neophytes) populations, hence, partially consequence successful turtle measures recoveries. observations Malaysia neophytes has also getting smaller over time: 99.6 between because foraging environments. While lower reproductive output, negative will often more than offset increases numbers occurring widely.
