13. Thermogenesis and post-prandial termophly in Bothrops moojeni (Serpentes: Viperidae) in captivity / Termofilia e termogênese pós-prandiais em Bothrops moojeni (Serpentes:Viperidae) em cativeiro
The study of the preferred temperatures and thermophilic behavior is essential to understand the snakes thermal biology. Although some studies have been reported, most of them are focused in temperate and diurnal species. Thus, little is known about the tropical and sub-tropical nocturnal species. In the present study , a video-monitored arena with a thermal

17. Tenacidade e investimento em seda em aranhas de teia orbicular / Tenacity and silk investment in orb web spiders
The origin of the most diverse branch of orbweavers, the Araneoidea, coincides with the origin of the viscid silk in the group Orbiculariae. Many hypotheses were proposed to explain the increased diversity in Araneoidea, however none of them explain this phenomena completely. The present work investigates a new hypothesis: the disappearance of the cribellate
