Abstract

ABSTRACT Coleopterans (Coleoptera) are major ecosystem service providers. However ecomorphological features that are comparable in a wide range of invertebrates within this group and in various environments must be found, to be able to study regions with different species, contributing to overcome difficulties of the taxonomic approach and understand the functioning of ecosystems. This research addressed the diversity of Coleoptera, using a methodology of ecomorphological traits, as well as their relation with the land use systems (LUS) and the soil [...]

Highlights

Coleopterans (Coleoptera), along with other faunal components, microorganisms, and plant roots, make up the soil biological system and act in chemical, physical, and biological processes (Bardgett and Van Der Putten, 2014)
The reductions in soil biological quality (SBQ) index were not associated with a gradient of land use intensification (NF> Eucalyptus stands (EST)> PA> croplivestock integration (CLI)> NT), and the index was higher for native forest (NF) and lower for EST
The density in summer was low only in EST compared to NF (Figure 1b)

Summary

Introduction

Coleopterans (Coleoptera), along with other faunal components, microorganisms, and plant roots, make up the soil biological system and act in chemical, physical, and biological processes (Bardgett and Van Der Putten, 2014) These invertebrates can be found in almost all environments and at various soil depths. Some even contribute to increase plant growth, due to their activity of incorporating manure into the soil (Scarabaeinae) (Nichols et al, 2008) Anthropogenic changes influence both coleopterans and the rest of the biota, directly or indirectly and at various levels and intensities, e.g., by the use of agrochemicals, intensive soil rotation, and especially changes in plant composition (Baretta et al, 2014; Lee and Albajes, 2016). As groups of soil Coleoptera affect the ecosystem functionality in many ways, these insects can respond immediately to ongoing changes in the habitat and indicate environmental conditions on and in the soil, as well as soil balance or disturbance levels, mainly related to management practices in agriculture and forest areas (Portilho et al, 2011; Gibb et al, 2017)
