Fatores que afetam a presença de inventário de artrópodes nas Unidades de Conservação Integral do Estado de São Paulo
Abstract
Arthropods are the most diverse and abundant animal group in nature and occupy varied environments playing ecological roles that directly and indirectly impact human wellbeing. Despite this, invertebrates in general do not receive the same attention for their conservation as other animal groups, even in legal areas intended for the protection of biodiversity. Therefore, this study aims to survey the presence of arthropod inventory in protected areas in the state of São Paulo, southeast Brazil, and identify which factors influence and may be crucial for carrying out inventories, since this is the main tool to allow
conservation measures for the taxon. For this, the management plans of the integral protection areas were checked to describe which one had inventories, which and how many orders were sampled. 61 protected areas were analyzed in the categories state park, ecological station and biological reserve. Only 13 protected areas (22%) presented inventories of arthropods. The orders that appeared the most were Lepidoptera, Hymenoptera and Diptera. The protected area with the most orders was Parque Estadual Turístico do Alto do Ribeira with 29 orders present in the management plan; on the other hand, Estação Ecológica Santa Bárbara had only 2 orders described in the management plan, being the smallest sample
among the protected areas with inventories. For the total number of inventoried orders in all protected areas there was a mean =10 and standard deviation =8.8. We tested the factors that potentially influence the occurrence of inventories (date of creation and size of the protected area, nearest distance to public universities, predominant biomes and availability of accommodation for researchers). Only the availability of accommodation positively influenced the presence of inventories (p=0,054). Therefore, the investment in protected areas infrastructure and the research aimed at the conservation of arthropods are essential steps to increase our knowledge about the biodiversity of those groups and allow their protection.
