Composição da comunidade da entomofauna de serapilheira e de fungos micorrízicos arbusculares em áreas sob processo de restauração no Parque Nacional da Serra do Itajaí no Vale do Itajaí, SC

Abstract

The objective of this work is to characterize and determine the population fluctuation of litter entomofauna in degraded areas in the restoration process with the techniques of restoration of roughness, without transposition of galleries and artificial poles, having a native forest as a reference. In the work done in the Serra do Itajaí National Park. The survey was conducted as winter seasons from 2014 to autumn 2016, totaling 8 pigtails. The characterization of the communities sampled was made by the identification of users and families by different faunistic indexes. Soil samples were collected to evaluate the mycorrhizal community in two different seasons. Between as winter seasons of 2014 and autumn of 2016 were collected 11,241 insects in areas visible with traps traps. The collected taxa belong to 57 taxonomic groups. The native forest has a higher observed richness. The only groups classified as frequent, constant and dominant in all environments were Hymenoptera (family Formicidae) and Diptera de orden. The highest frequency index of the forms found in the technique of transposing galharias, with 88% in the spring of 2015. Among the constant groups there was a significant difference in the frequencies observed for the families Ptiliidae and Staphylinidae of the order Coleoptera, family Cicadellidae Of the order Hemiptera And the insects of the order Diptera. Among the groups classified as accessory and accidental, there was no significant difference in the observed frequencies of any of the groups present in the studied areas. As families Ptiliidae, Staphylinidae and the subfamily Scolytinae all of the Coleoptera order, have potential as bioindicators of environmental quality. The estimation of the total number of taxa in the different environments studied indicates that the expected wealth was always higher than the real value found. Interpretation from the Shannon index confers an area of roughness as the most diverse, and the less diverse the galleries. There was a significant statistical difference in forest diversity as areas of galleria and perch. The highest qualitative similarity was observed between forest and regeneration. 33 species of mycorrhizal fungi were identified, with three families and 11 genera. The family most represented for Acaulosporaceae
