Food strategy and diving behaviour optimization of sea turtles

Sea turtles are long-distance migrants with some travelling several thousand kilometres. This lifestyle makes visual observation problematic. Given that some sea turtle populations are subject to substantial anthropogenic pressures, any information pertaining to their ecology is valuable. A development over the last 20 years, has been the tag-linked accelerometers, which has proven particularly powerful in providing data that enable us to elucidate animal behaviour remotely. A solution to define the ecological needs of these enigmatic animals?

The impact of helpers on offspring potential lifespan in sociable weavers (Philetairus socius)

The impact of helpers has been studied through the potential benefits for parents (survival and reproduction rate). However, the effects on offspring have been less explored, especially regarding the long-term survival. We used a cross-fostering protocol and telomere analysis to assess the impact of helpers on offspring potential lifespan. We showed that the impact of helpers seems to be time-dependent.
