Distribution of gall-inducing arthropods in areas of deciduous seasonal forest of Parque da Sapucaia (Montes Claros, MG, Brazil): effects of anthropization, vegetation structure and seasonality
Abstract In the present study, we inventoried gall-inducing arthropod species and evaluated the effects of habitat anthropization, vegetation structure and seasonality on this group in areas of deciduous seasonal forest of Parque da Sapucaia, Montes Claros, MG, Brazil. The gall-inducing fauna was sampled between April 2017 and February 2018 from 20 plots distributed in anthropized and preserved habitats. A total of 29 morphospecies of gall-inducing arthropods and 21 species of host plants were recorded. The Fabaceae plant family had the highest number of gall morphospecies (n = 10), while the Cecidomyiidae (Diptera) insect family induced the most galls (41.3%). Mean gall richness did not differ between preserved and anthropized plots, but was negatively affected by mean vegetation height and density. The total number of gall morphospecies recorded during each sampling did not differ between dry and rainy seasons, but the mean richness of galls per plot was higher in the rainy season. In conclusion, natural factors, such as vegetation structure and seasonality, were more important for the distribution of gall-inducing species than anthropic factors, such as vegetation anthropization level.
