Nesting Site Preference of Marine Turtles in the Central Red Sea

Student thesis: Master's Thesis


Oviposition habitat is important to species with no protracted parental care. For sea turtles, nest site selection may affect offspring fitness through microenvironmental characteristics such as moisture, beach slope, temperature and grain size. Climate change and coastal development will result in changes of nest site characteristics. In particular in Saudi Arabia, with the advent of tourism, there will be development of giga-projects such as the crossborder city of NEOM and luxury tourist resort ‘The Red Sea Project’. To evaluate the different beach characteristics, we assessed the change in parameters over the nesting season, differences in microenvironmental characteristics with regard to nest distribution and compared differences between low- and high- density nesting sites in the central Red Sea, during the 2019 nesting season. We sampled on a biweekly basis, taking various insitu measurements and collecting sand samples to be analysed for grain size, moisture content and colour. HOBO temperature loggers were deployed at sites where nesting occurred. At our low- density sites nest distribution was dictated mainly by angle of beach slope, ANOVA (P
