Abstract
BACKGROUND: The knowledge of the factors that affect the geographic distribution of species permits us to infer where they can be found. Human beings, through the expansion of their own distribution area and their contribution to climate alteration have modified the geographic distribution of other biological species. As a consequence, the temporal pattern of co-occurrence of human beings and venomous species (scorpions, spiders, snakes) is being modified. Thus, the temporal pattern of areas with risk of accidents with such species tends to become dynamic along time. The aim of this work was to analyze the areas of occurrence of species of Tityus in Argentina and assess the impact of global climate change on their area of distribution constructing risk maps.
METHODS: Using data of occurrence of the species and climatic variables, we constructed models of species distribution (SMDs) under current and future conditions. We also created maps that allow the detection of temporal shifts in the distribution patterns of each Tityus species. Finally, we constructed risk maps for the analyzed species.
RESULTS: Our results predict that climate change will have an impact on the distribution of Tityus species which will clearly expand to more southern latitudes, with the exception of T. argentinus. T. bahiensis, widely distributed in Brazil, showed a considerable increase of its potential area (ca. 37%) with future climate change. The species T. confluens and T. trivittatus that cause the highest number of accidents in Argentina, showed significant changes of their distributions in future scenarios. The former fact is worrying because Buenos Aires province is the more densely populated federal district in Argentina thus liable to become the one most affected by T. trivittatus.
DISCUSSION: Then, these alterations of distributional patterns can lead to amplify the accident risk zones of venomous species, becoming an important subject of concern for public health policies.
