Collembola community structure under different land management in subtropical Brazil

Abstract

Tillage systems in conservation agriculture such as no‐tillage (NT) and crop‐livestock integration (CLI) have been proposed to limit the negative impacts of intensive agriculture. Soil organisms such as Collembola are good indicators because they respond to a variety of environmental and ecological factors and their community structure indicates a change in land management. In this study, we propose to assess the relationships between springtail biodiversity in management systems with a history of NT and CLI. For both management systems, nine points were sampled, distributed in a 30 × 30 m sampling grid, in three municipalities on the Southern Santa Catarina Plateau, Brazil. Springtails were collected using a metal cylinder (5 cm diameter × 5 cm deep) and identified at the species level. At the same point, samples were collected to evaluate soil properties (chemical, physical and microbiological). In total, 538 individuals were collected, distributed in 24 species, 293 individuals (18 species) in NT and 245 individuals (17 species) in the CLI system. Soil management systems studied did not affect the total number of individuals and richness. The NT system had a greater association with epigeic species, while the CLI system was more associated with hemiedaphic and edaphic species, which is related to the site‐specific differences in soil conditions. In both soil management systems, the species were influenced by a range of soil properties. The species Isotomurus sp. 1 and Lepidocyrtus sp. 1 were more influenced by soil properties in the NT system, while the species Proisotoma sp. 1, Sminthurinus sp. 1 and Tullbergia antarctica were more influenced by soil properties in the CLI system, compared to the others. Collembola community structure and species diversity were modified by the soil management systems. Our results suggest that the Collembola community may indicate changes across land management systems in conservation agriculture.

Grassland management intensification affects the soil fauna in a subtropical highland

“…Adult and larval Coleoptera were studied separately because of their different morphologies and potential functional roles from adult Coleoptera (Fountain‐Jones et al, 2015; Gongalsky, 2021). Morphotyping identification has been performed for Collembola and Coleoptera (de Filho et al, 2016; Oliveira Filho et al, 2020; Parisi et al, 2005; Pompeo et al, 2017). Enchytraeidae have been identified at the genus level (Schmelz & Collado, 2010).…”

Soil macrofauna in areas with different successional vegetation stages after Eucalyptus grandis harvest in Brazil

“…Therefore, the specificity and fidelity of ant species to a habitat suggests that these species can be used as environmental indicators in the recovery of forest areas (Schmidt, Ribas, & Schoereder, 2013). Oliveira et al, 2020). Collembola are in a constant process of formation and fragmentation of litter; they feed on debris and microorganisms and are fundamental in the decomposition of organic matter (Hopkin, 1997).…”

“…In this context, monitoring of soil macrofauna is a method of assessing the functioning of the forest system since it is closely associated with the processes of decomposition and nutrient cycling at the soilplant interface (Correia & Oliveira, 2000;Mello et al, 2009). Several studies have focused on macrofauna as indicators of soil quality, with the aim of understanding how soil uses interfere with their distribution (Oliveira, Zeppelini, Sousa, Baretta, & Klauberg, 2020;Pompeo, Oliveira, Klauberg, Mafra, & Baretta, 2020;Pereira et al, 2021). In the Vale do Itajaí Region in Santa Catarina State, Brazil, few studies have evaluated the populations of terrestrial invertebrates as indicators of soil quality (M. A.…”

“…Springtails are also considered as relevant bioindicators of land use change [ 19 , 20 , 21 ]. They are also used as biological indicators to assess the impact of different agricultural practices on soil biodiversity [ 22 , 23 , 24 , 25 ].…”
