Abstract

Invasion of species is one of the main threats to biodiversity conservation. Although not every introduction of species results in invasion, aliens species commonly cause severe impact both to humans and wildlife, so it is very important to understand the interaction of aliens with the new environments. In this respect, this work aims to investigate European Hare occupancy association with heterogeneity and agricultural crops cycle that occur near the limit of its geographical expansion front. Besides, the patterns of co-occurrence between the European Hare, Lepus europaeus Pallas, 1778, an exotic species introduced in South America, and tapiti, Sylvilagus brasiliensis (Linnaeus, 1758), the single native lagomorph of Brazil, will be investigated. The study will sample 60 agricultural landscapes in the interior of São Paulo and will be based on data from complementary sampling methods (direct sampling with camera-traps and indirect sampling in transects). Analyzes will involve occupation models at multiple scales, explicitly dealing imperfect detection (<1). The landscapes to be sampled will have a wide spatial distribution (centers distant from each other for at least 6180 m) and were selected based on criteria that maximize the variance of predictors of interest and minimize the interference of uncontrolled factors. This study intends to broaden the understanding of European Hare invasion in Brazil, generating results that will have implications not only for the conservation of the native fauna but also for the agricultural policy and economy in general.
