With the increasing devastation of the tropical rain forest, there is a critical need to understand how animal forest communities are structured and how habitat degradation will affect these communities. We conducted a field survey to investigate the microhabitat preferences of two co-occurring species of scorpions (Tityus pusillus and Ananteris mauryi) in(More)
Habitat fragmentation is a topic widely studied in ecology; however, its effects on the assemblage of the order Scorpiones is less well understood. Aiming to fill this gap, this study assessed the effect of fragmentation on the assemblage of these arachnids in 12 Brazilian Atlantic forest fragments. Five environmental variables were measured (depth and dry(More)
Scorpions are generalist predators, capturing a great variety of arthropods including even small vertebrates (Polis, 1990), however, they are also subject to predation, especially by vertebrates such as amphibians, reptiles, birds and mammals (Polis et al., 1981; McCormick and Polis, 1990). Regarding the invertebrates, there are reports of predation by(More)
Venom demands high metabolic costs of the organisms that produce it because it is comprised of a complex mixture of various toxins. Due to this high cost, venomous animals modulate the amount or type of venom used depending on factors such as size of prey or intensity of predation threat. This paper shows that Tityus stigmurus, a prevalent scorpion species(More)
