“…The increase of one species of Collembola in relation to others was also discussed by Fountain et al (2007) when investigating the effect of organophosphate insecticide (Chlorpyrifos) in spider and collembola communities. However, the authors observed an increase in the total number of the Collembola Ceratophysella denticulate and the reduction of seven other species.…”

“…Freire et al (2015) and Tessaro et al (2016) emphasize that variations in soil composition and management directly influence soil organisms, which in turn are directly influenced by abiotic factors. There are several works what considering the temperature and soil moisture in studies of synecology, prioritizing the composition, frequency and distribution of soil fauna, however, little is known about their interrelationships (PONGE, 1993;PAKHOMOV et al 2013).…”

RESUMO:O presente estudo teve como objetivo avaliar a população da fauna edáfica em uma área experimental instalada há 26 anos em Pato Branco / PR. Entre os tratamentos existentes na área experimental, foram selecionados seis manejados sob sistema de cultivo convencional, e seis manejados sob plantio direto, ambos cultivados com seis diferentes plantas de cobertura. O método empregado para a extração de organismos edáficos (camada 0-10 cm) foi o do Funil de Tüllgren. A execução das coletas se deu em blocos e repetições (156 amostras de solo para quantificar a fauna edáfica; 156 para avaliar a umidade do solo e 156 leituras de temperatura do solo). Em abril/2013, foram estimados 60.138 indivíduos m -2 e em janeiro/2014 foram 28.348 indivíduos m -2 . A adoção do plantio direto por longo período favorece a biodiversidade da fauna do solo em relação ao solo que vem sendo feito revolvimento com duas lavrações e quatro gradagens anuais desde 1976. Os táxons edáficos mais representativos em abril/2013 foram Acari, Collembola e Diptera, e em janeiro/2014 foram Acari, Collembola, Hymenoptera e Larva de Lepidoptera. O manejo fitossanitário das áreas influencia na diversidade da fauna edáfica. O fator abiótico umidade do solo atua de forma severa sob a fauna edáfica, sendo mais evidente no sistema de cultivo convencional. A época de coleta influencia na densidade de indivíduos, na riqueza de espécies e nos índices de Shannon e Pielou.Palavras-chave -macrofauna, mesofauna, plantas de cobertura de inverno.ABSTRACT -The present study had as objective to evaluate the soil fauna population, in an experimental sites installed for 26 years in Pato Branco / PR. Among the treatments existent in the experimental site, were selected six managed under Conventional Farming System, and six managed under No-tillage, both cultivated with six different cover plants. The method used for the extraction of edaphic organisms (0-10 cm depth) was Tüllgren funnel. The collection was done in blocks and replicates (156 soil samples to quantify the soil fauna; 156 to evaluate soil moisture, and 156 soil temperature readings). In the April/2013, 60,138 m -2 individuals were estimated, and in the January/2014 they were 28,348 m -2 individuals. The adoption of the long-term No-tillage favors the biodiversity of the soil fauna in relation to the soil that has been undergoing two years of cultivation and four annual harrows since 1976. The most representative edaphic taxon in the April/2013 were Acari, Collembola and Diptera, and in the January/2014 they were Acari, Collembola, Hymenoptera and Larva of Lepidoptera. The phytosanitary management of the areas influence the diversity indexes of the edaphic fauna. The soil moisture abiotic factor acts severely under the edaphic fauna, being more evident in the conventional cropping system. The collection season conditioned to the abiotic factors -soil moisture and temperature -influences the density of individuals, species richness and the Shannon and Pielou indexes.

“…The mesofauna samples were extracted using Berlese-Tüllgren funnels, a method widely used due to its practicality and low cost. It involves transferring the soil into stainless steel funnels under 25W incandescent lamps over ten days (Freire et al, 2015). At the top of the funnels is a heat source, while at the bottom is a container with a 70% alcohol solution.…”

Land use change (LUC), specifically the cultivation of monoculture sugarcane, can negatively impact soil biodiversity, leading to a decline in soil health and ecosystem functioning. However, while studies focusing on macrofauna and microorganisms are more frequent in the literature, the impacts of LUC on mesofauna are still little known. Therefore, this study aimed to investigate the impacts of the predominant LUC for sugarcane production in Brazil on the diversity of edaphic mesofauna in soils with contrasting textures. In addition, we assessed correlations between biodiversity and soil properties chemical, biological, and physical attributes. We took samples from two sites (clayey and sandy soils) in southeastern Brazil. The sequence of LUC included i) native vegetation (NV), ii) pasture (PA), iii) sugarcane (SC), and iv) sugarcane ratoon (SCr). In the rainy season, monoliths (25 x 25 x 10 cm), soil samples were collected at 0-10, 10-20, and 20-30 cm to assess soil mesofauna, soil chemical (pH, soil organic matter, phosphorus, sulfur, potassium, calcium, magnesium, potential acidity, cation exchange capacity), physical (soil porosity) and biological (microbial biomass carbon and nitrogen) properties. The mesofauna taxonomic groups were quantified after the classification. Briefly, a total of 22 taxonomic groups were classified. The most predominant groups were non-oribatid mites, oribatid mites, and Collembola. Richness and abundance were lower in the three land uses studied (PA, SCr, SC) compared to the intercept (NV). In clayey soil, diversity decreased from NV to PA (-0.68 ± 0.27) and SC (-0.55 ± 0.27) but not to SCr. In sandy soil, land use significantly impacted the mesofauna diversity and evenness index, significantly reducing these indexes in SCr in relation to NV. Although land use change towards more intensified systems resulted in a loss of richness and abundance of soil mesofauna, sugarcane cultivation over the years can recover the diversity of mesofauna in clay-textured soils. These results provide a scientific background to better understand the LUC effects on sugarcane cultivation and support the establishment of sustainable practices that enhance soil health and biodiversity in different soil textures. This study highlights the need for tailored land management considering soil texture and biodiversity for improved ecosystem services.

“…The samples were collected and stored in polyethylene bags and taken to the laboratory for processing. In the lab, they were mounted in a Berlesse-Tullgren system for 7 days in order to ensure the extraction of soil organisms [45]. Organisms were collected in 75% alcohol and stored in glass vials.…”

Home gardens play a transcendental role in food sovereignty, for which the management of habitats above ground and underground are complementary strategies. This study aims to compare the biodiversity of soil mesofauna groups between agroecosystems with a conventional and an agroecological design. Through the combination of quantitative (plant inventories) and qualitative (mobile interviewing and talking maps) techniques, the units of this study was described. Soil samples were mounted in a Berlesse–Tullgren system, and the abundance, richness, diversity, and equality of soil organisms were determined. The relationships between functional groups were compared taxonomically and biocenotically. The results indicated higher equality in the conventional home garden, while the communities studied present a medium taxocenotic similarity, without great biocenotic differences. The diversity and richness of taxa, as well as the abundance in each group identified, were higher in the agroecological garden, which had more medicinal and aromatic plants.
