Abstract

Insects stand out for their diversity, representativeness, ecological importance, and sensitivity to environmental changes that are affected by anthropogenic changes in natural ecosystems. This study aimed to characterize the leaf litter insect fauna in four different areas that included two native forests and two pastures in Serra do Itajaí National Park. Data were collected from August 2014 to August 2015 from pitfall trap installations. The abundance, richness, diversity, family composition, and functional groups were analyzed. In total, 16,062 individuals were collected that were distributed across 16 orders and 101 families. Abundance, family richness, and diversity were similar among the areas. However, the composition differed, demonstrating that the environments possessed different insect fauna communities based on the composition of families. The Coleoptera order with the Ptiliidae family was more abundant in the native forest, while the Hemiptera (Cercopidae and Cicadellidae) were more abundant in the pasture area. The composition of fungivores and phytophagous fungi differed significantly among the areas. The number of exclusive families and their composition demonstrated a leaf litter insect fauna that was adapted to the environmental conditions and resources available within each environment

不同植物覆盖层落叶昆虫区系的结构和功能特征

昆虫以其多样性、代表性、生态重要性和对自然生态系统中受人为变化影响的环境变化的敏感性而脱颖而出。本研究旨在描述Serra do Itajaí国家公园四个不同区域的凋落叶昆虫区系特征，包括两个原生林和两个牧场。数据收集于2014年8月至2015年8月的陷阱装置。对其丰度、丰富度、多样性、科组成和功能类群进行了分析。总共收集了16,062只个体，分布在16个目和101个家庭。丰富度、家庭丰富度和多样性在各地区相似。但其组成存在差异，说明不同环境下昆虫区系的组成存在差异。原生林以蚁科鞘翅目昆虫较多，而牧区以半翅目蚁科和蝉科昆虫较多。各地区食真菌和植食真菌的组成差异显著。特有科的数量及其组成表明，凋落叶昆虫区系与不同的环境条件和资源相适应
