摘要: As part of a fragmented landscape, yerba mate and tea are perennial agroecosystems that provide habitat continuity for diverse arthropods. Our objective was to characterize the influence these two on native fauna salticids, measuring levels richness, diversity, density. We hypothesized studied do not differ in their capacity function as reservoirs regional spiders. Each sample comprised suctioning vegetation an area 1 m³ one minute using Garden-Vacuum. Twenty-five species salticids were found. Naubolus posticatus, Chira spinosa, Scopocira histrio Maeota dichrura dominant, accounting more than 20% total. Spider densities similar, 2.21 2.47 individuals/m³ tea. The complexity plants adequate accommodating several salticids. Both crops also similar richness shared at least 44% species, held fifth known Misiones Atlantic Forest. discovery from adjacent ecoregion suggests serve reservoir can act corridors ecotone zone.
