Does human influence on coastal grasslands habitats affect predation pressure on snakes?

Abstract: Abstract:The loss and modification of habitats by humans have been considered key factors in the decline of diversity of species worldwide. However, the real effect caused by these disturbances on the biota is still poorly understood. The assessment of the changes in the network of interspecific interactions, such as predation rates on the native fauna, can be an important tool to diagnose the functionality of disturbed ecosystems. In this study we evaluate the predation rate on snakes in coastal grasslands in… Show more

“…Where potential predators attack the models, they leave quantifiable evidence as beak, claw or teeth marks (e.g. Webb & Whiting, ; Dell'Aglio et al ., ; Santos et al ., ; Fresnillo, Belliure & Cuervo, ), or if the models are removed entirely, they can leave predator tracks nearby.…”

“… e ndings of this study may serve as a basis for other studies involving aposematic coloration as anti-predation mechanism, considering that the present study has a short sampling period. In addition, this methodology may be used to test other hypothesis, such as the investigation of the relationship between the predation rate and the functionality and level of preservation of habitats, as seen in Santos et al (2013).…”
