INFLUENCES OF THE LOCAL CLIMATE AND NESTING ENVIRONMENT ON

LOGGERHEAD SEA TURTLE (Caretta caretta) HATCHLING OUTPUT

Local climate influences sea turtle hatching and emergence success with climatic extremes affecting embryonic development and hatchling emergence. Thus, it is crucial to understand how different climatic variables affect hatchling output presently and explore how potential changes in climate may impact future hatchling output and sea turtle population stability. This thesis investigates the influences of six climatic variables (air and sea surface temperature, precipitation, humidity, wind speed, and solar radiation) on the hatchling output of the loggerhead sea turtle (Caretta caretta) for two distinct nesting populations: Southwest Atlantic Loggerhead Regional Management Unit which nest in Brazil and the Northern Gulf of Mexico Loggerhead Recovery Unit, which nest in North Florida, USA. Additionally, this thesis examines how potential changes in climate may impact future hatchling output. The main drivers of hatchling output varied across sea turtle populations, nesting regions, and beaches. In Brazil, air temperature and precipitation were found to be the main climatic drivers of hatchling output, whereas in North Florida as well as air temperature and precipitation, humidity was a significant climatic driver of hatchling output. Climate projections show air temperatures warming at all sites throughout the 21st century, while projections for precipitation and humidity varied regionally. Our projections indicate that by 2100, tropical nesting beaches (Bahia, Brazil) will experience declines in hatchling output, while temperate regions (Espirito Santo and Rio de Janeiro in Brazil and North Florida) will experience increases in hatchling output. Our results highlight the need to conduct assessments of the climatic drivers of hatchling output at a regional scale, especially in temperate areas, to better understand how projected changes in climate may impact populations and better inform management and conservation initiatives.
