  3. 2. Feeding Behaviour in Loggerhead Sea Turtles (Caretta caretta) : Collection of Movement Data Representative of Feeding Events

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Marie Ulrich; [2019]
    Nyckelord :Clams; Crabs; Data logger; Calcium; Loggerhead; VeDBA; feeding behaviour;

    Sammanfattning : With the different threats sea turtles are currently facing, such as habitat reduction and pollution, increase of fishing and harvesting of aquatic resources by Humans, or invasive species, it is important to learn as much as possible about their biology and behaviour in order to ensure the success of conservation programs. In this study, loggerhead sea turtles (Caretta caretta) feeding behaviour duration as well as energy expenditure approximation during a feeding event were tested and compared using two different types of food: green shore crabs (Carcinus maenas) or Japanese clam (Ruditapes phillipinarum) or Venus clams (Chamelea gallina).
