Influence of ZnO Nanoparticles and a Non-Nano ZnO on Survival and Reproduction of Earthworm and Springtail in Tropical Natural Soil

Micheli Lucia Alves, Luís Carlos Iuñes de Oliveira Filho ORCID logo , Patrícia Nogueira, André Junior Ogliari, Márcio Antônio Fiori ORCID logo , Dilmar Baretta ORCID logo , [...]


ABSTRACT: In recent years, various studies and development using nanoparticles (NPs) have been carried out in the most diverse areas of knowledge. Although nanomaterials are widely employed by many sectors and some may have a fertilizing potential, little is known about their effects on the environment. This study aimed to evaluate the effect of applying, in tropical natural soil, different contents of nanoparticles of zinc oxide (NPs-ZnO) and non-nano zinc oxide (ZnO) on soil pH and on the survival and […]

Morphological Diversity of Springtails in Land Use Systems

Marcielli Aparecida Borges dos Santos, Luís Carlos Iuñes de Oliveira Filho, Pâmela Niederauer Pompeo, Danielle Cristina Ortiz, Álvaro Luiz Mafra, Osmar Klauberg Filho, [...]


ABSTRACT: Springtails (Collembola) are soil organisms with wide morphological diversity and are sensitive to alterations in the soil, regardless of whether they are human-caused or not. The aim of this study was to evaluate the influence of land use on the morphological diversity of springtails and verify their relationships with soil physical, chemical, and microbiological properties. Samples were collected in the eastern region of Santa Catarina, in three municipalities: Joinville, Blumenau, and Timbó. They included the following land use systems […]

Spiders (Arachnida: Araneae) in Agricultural Land Use Systems in Subtropical Environments

Marcio Gonçalves da Rosa, Júlio Cesar Pires Santos, Antônio Domingos Brescovit, Álvaro Luiz Mafra, Dilmar Baretta


ABSTRACT Changes in land use management in agricultural areas can affect the biodiversity of spider families. This study aimed to evaluate spider diversity in different land use systems with capture by two sampling methods, and to identify soil properties that can modulate the occurrence of spiders. Five land use systems, representative of traditional agricultural areas, were evaluated in the west of Santa Catarina, Brazil, to establish a scale of land use intensity: native forest, eucalyptus reforestation areas, pastures, crop-livestock integration […]

Soil Macrofauna as a Soil Quality Indicator in Native and replanted Araucaria angustifolia Forests

Jamil de Morais Pereira, Julia Corá Segat, Dilmar Baretta, Rafael Leandro de Figueiredo Vasconcellos, Carolina Riviera Duarte Maluche Baretta, Elke Jurandy Bran Nogueira Cardoso


ABSTRACT Studies on soil quality in Araucaria forests contribute to understanding changes in this ecosystem and serve as a tool in conserving its biodiversity. The aim of this study was to evaluate the potential of soil macrofauna in discriminating native and replanted Araucaria forests for selection of soil quality indicators. Native (NF) and replanted (RF) Araucaria angustifolia forests were evaluated in three regions of the state of São Paulo, representing three true replications. Fifteen soil samples were collected in each […]

Morphological Diversity of Coleoptera (Arthropoda: Insecta) in Agriculture and Forest Systems

Pâmela Niederauer Pompeo, Luís Carlos Iuñes de Oliveira, Marcielli Aparecida Borges dos Santos, Álvaro Luiz Mafra, Osmar Klauberg, Dilmar Baretta


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 […]

Collembola Community Structure as a Tool to Assess Land Use Effects on Soil Quality

Luís Carlos Iuñes de Oliveira Filho, Osmar Klauberg Filho, Dilmar Baretta, Cynthia Akemi Shinozaki Tanaka, José Paulo Sousa


ABSTRACT: Collembolan species are differently affected by soil tillage (conventional, minimum tillage, and no-tillage) and are known to modify plant growth. This study relies on the relationships between Collembola community structures and land use systems as a proxy for characterizing changes in soil quality. Thus, Collembola community structure (eco-morphological groups – edaphic, hemiedaphic and epigeic, and morphotypes) were examined in a no-tillage system and crop-livestock integration system to evaluate the discriminative power of the Collembola community structure and to determine […]

Abundance and Diversity of Soil Macrofauna in Native Forest, Eucalyptus Plantations, Perennial Pasture, Integrated Crop-Livestock, and No-Tillage Cropping

Sheila Trierveiler de Souza, Paulo Cezar Cassol, Dilmar Baretta, Marie Luise Carolina Bartz, Osmar Klauberg, Álvaro Luiz Mafra, [...]


ABSTRACT Intensive land use can affect macrofaunal biodiversity, which is a property that can be used as a soil quality indicator. This study evaluated the abundance and diversity of soil macrofauna and its relation to soil chemical and physical properties in five land use systems (LUS) in the eastern region of Santa Catarina. The following LUS were studied: native forest (NF), eucalyptus plantations (EP), perennial pasture (PP), integrated crop-livestock (ICL), and no-tillage cropping (NT). The macrofauna was quantified in 0.25 […]

Soil Macrofauna and Physical and Chemical Properties under Soil Management Systems in the Santa Catarina Highlands, Brazil

Marcio Gonçalves da Rosa, Osmar Klauberg, Marie Luise Carolina Bartz, Álvaro Luiz Mafra, José Paulo Filipe Afonso de Sousa, Dilmar Baretta


ABSTRACT Soil use can change processes such as soil organic matter decomposition, nutrient cycling, and particle aggregation, which, in turn, influence the occurrence of macrofauna. The objective of this study was to relate land use systems to their effects on the distribution of soil macrofauna groups, as well as their relation to soil physical and chemical properties. The land use systems evaluated were native forest, an Eucalyptus plantation, pasture, a crop-livestock integration area, and a no-tillage crop area. Samples were […]

ABSTRACT The disposal of large amounts of coal mining waste chemically modifies the soil, and this may change the structure and activity of soil fauna. The objective of this investigation was to study the ecotoxicological effects of depositions of pyritic waste (coal plus pyrite) in two soils collected in Santa Catarina, Argissolo Vermelho-Amarelo (Ultisol) e Nitossolo Háplico (Hapludox), at the application rates of 0, 2.5, 5, 10, and 20 % of that residue. Survival and reproduction of Enchytraeus crypticus and […]

Relationships between microbial activity and soil physical and chemical properties in native and reforested Araucaria angustifolia forests in the state of São Paulo, Brazil

Jamil de Morais Pereira, Dilmar Baretta, Daniel Bini, Rafael L. de F. Vasconcellos, Elke Jurandy Bran Nogueira Cardoso


Araucaria angustifolia (Bert.) O. Kuntze is the main component of the Mixed Ombrophilous forest and, in the State of São Paulo, it is associated with a high diversity of soil organisms, essential for the maintenance of soil quality, making the conservation of this ecosystem a major and pressing challenge. The objective of this study was to identify the physical and chemical properties that are most closely correlated with dehydrogenase enzyme activity, basal respiration and microbial biomass under native (NF) and […]
