Niche modelling of the Chilean recluse spider Loxosceles laeta and araneophagic spitting spider Scytodes globula and risk for loxoscelism in Chile.

摘要: In Chile, all necrotic arachnidism is attributed to the Chilean recluse spider Loxosceles laeta (Nicolet) (Araneae: Sicariidae). It predated by spitting Scytodes globula Scytodidae). The biology of each these species not well known and it important clarify their distributions. aims this study are elucidate variables involved in niches both based on environmental human footprint variables, construct geographic maps that will be useful estimating potential distributions defining a map estimated risk for loxoscelism Chile. was found associated with high temperatures low rates precipitation, whereas although S. globula also temperatures, its distribution higher level precipitation. main variable L. laeta (48.6%), which suggests highly invasive species. Similarly other species, reaches southern limit at Los Lagos region coincides levels precipitation temperatures. Chile corresponds cases loxoscelism.
