Autores: Bartz,Marie Luise Carolina; Brown,George Gardner; Pasini,Amarildo; Fernandes,Juliana de Oliveira; Curmi,Pierre; Dorioz,Julie; Ralisch,Ricardo.
The objective of this work was to evaluate the effect of organic and conventional coffee crops on biomass, population density and diversity of earthworms, in Lerroville, district of Londrina County, Paraná state, Brazil. Earthworm communities were sampled in three areas with organic coffee cultivation (CO1, CO2 and CO3), two with conventional coffee (CC1 and CC2), and a native forest fragment (MT). The soil of the areas CO1, CC1, and MT was classified as Nitossolo Vermelho (Rhodic Kandiudox), while CO2, CO3, and CC2 were on Latossolo Vermelho (Rhodic Hapludox). Eight samples were taken in each area on two occasions, winter and summer, using the Tropical Soil Biology and Fertility (TSBF) method in the 0-20 cm soil layer. The earthworms were handsorted and...

Earthworms from Mato Grosso, Brazil, and new records of species from the state
Provedor de dados: 86
Autores: Bartz,Marie Luise Carolina; Pasini,Amarildo; Brown,George Gardner.
The objective of this work was to undertake a qualitative assessment of earthworm diversity in areas under human influence, in a region of Cerrado-Pantanal-Amazon rainforest transition, in the state of Mato Grosso, Brazil. The earthworms were collected in the municipalities of Barra do Bugres and Arenápolis, and were studied together with species previously identified from other municipalities. Seventeen municipalities, at 29 sampling points of Mato Grosso State, have been sampled. Seven species of earthworms were collected and identified in Barra do Bugres: Goiascolex vanzolinii, Pontoscolex (Pontoscolex) corethrurus, Opisthodrillus borellii borellii, Opisthodrillus sp., Dichogaster (Diplothecodrilus) gracilis, Dichogaster sp. and a species of the...

Abundance and Diversity of Soil Macrofauna in Native Forest, Eucalyptus Plantations, Perennial Pasture, Integrated Crop-Livestock, and No-Tillage Cropping
Provedor de dados: 90

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 × 0.25 m monoliths and sampled in the 0.00-0.20 m layer in the summer (Jan/2012) and winter (Jul/2012). For each LUS, nine points were sampled, distributed in a 30 × 30 m sampling grid. After screening the edaphic macrofauna...

Macrofauna Edáfica e Atributos Físicos e Químicos em Sistemas de Uso do Solo no Planalto Catarinense
Provedor de dados: 90
Autores: Rosa,Marcio Gonçalves da; Klauberg Filho,Osmar; Bartz,Marie Luise Carolina; Mafra,Álvaro Luiz; Sousa,José Paulo Filipe Afonso de; Baretta,Dilmar.
RESUMO O uso do solo pode alterar processos como decomposição da matéria orgânica, ciclagem de nutrientes e agregação das partículas e, com isso, influenciar a ocorrência da macrofauna. Objetivou-se com este estudo relacionar os sistemas de uso do solo e os efeitos deles sobre a distribuição de grupos da macrofauna do solo, bem como a relação desses com os atributos físicos e químicos do solo. Os sistemas de uso do solo avaliados foram: floresta nativa, reflorestamento de eucalipto, pastagem, integração lavoura-pecuária e lavoura com sistema plantio direto. As amostras foram coletadas em uma grade de amostragem de 3 × 3, totalizando nove pontos, distanciados entre si em 30 m, no inverno e verão, em três municípios do Planalto Sul-catarinense, considerados...

The influence of land use systems on soil and surface litter fauna in the western region of Santa Catarina
Provedor de dados: 124
Autores: Bartz,Marie Luise Carolina; Brown,George Gardner; Orso,Renato; Mafra,Álvaro Luiz; Baretta,Dilmar.
The aim of this study was to evaluate the abundance of soil and surface litter fauna in the western region of Santa Catarina state, southern Brazil, in the following land use systems (LUS): no-tillage crops (NT), integrated crop-livestock (ICL), pasture (PA), Eucalyptus plantation (EP) and native forest fragments (NF). Sampling was done in three counties in the western region of Santa Catarina: Xanxerê, Chapecó and São Miguel do Oeste, in two seasons (winter and summer). The evaluation of soil/litter fauna in each LUS was performed by installing nine "pitfall traps" per sampling grid (3 x 3). The counties are true replicas. The soil for the chemical attributes was collected at the same sampling points for soil fauna. Altogether, 17 taxa were identified in...

Soil fauna and its relation with environmental variables in soil management systems
Provedor de dados: 124
Autores: Baretta,Dilmar; Bartz,Marie Luise Carolina; Fachini,Ivandro; Anselmi,Rafael; Zortéa,Talyta; Baretta,Carolina Riviera Duarte Maluche.
The present study aims to generate knowledge about the soil fauna, its relation to other explanatory environmental variables, and, besides it, to select edaphic indicators that more contribute to separate the land use systems (LUS). Five different LUS were chosen: conventional tillage with crop rotation (CTCR); no-tillage with crop rotation (NTCR); conventional tillage with crop succession (CTCS); no-tillage with crop succession (NTCS) and minimum tillage with crop succession (MTCS). The samples were made in the counties Chapecó, Xanxerê and Ouro Verde located in the state of Santa Catarina, Brazil, and were considered the true replicates of the LUS. In each site, nine points were sampled in a sampling grid of 3 x 3. At the same points, soil was sampled...

Abstract: Several studies have characterized and delimited subterranean ant assemblages. Soil extraction, one of the methods employed to access this fauna, employs the removal of monoliths. One of the most widely used methods for the extraction of soil sampling is called TSBF (developed by the Tropical Soil Biology and Fertility Programme). This method provides relevant data about the species associated with the soil. In the present study we characterized assemblages of subterranean ants using the TSBF method in different subtropical areas of the Neotropics. We considered two sampling designs in different localities. The first design resulted in 315 TSBF samples obtained from layers at distinct depths. The second design resulted in 270 TSBF samples and 270...

Provedor de dados: 65
Autores: Simioni,Flávio José; Bartz,Marie Luise Carolina; Wildner,Leandro do Prado; Spagnollo,Evandro; Veiga,Milton da; Baretta,Dilmar.
ABSTRACT: This study aimed to evaluate the relationship between economic indicators of soybean crops ( Glycine max L.) cultivated with Crop-Livestock Integration (CLI) or with grain production in winter, and the chemical, physical and biological attributes of the soil. It was selected ten agricultural sites in Santa Catarina to measure economic results and edaphic attributes, data was submitted to a Principal Components Analysis (PCA). Results indicated that soybean production in the summer and grain production in the winter yielded better economic results compared with summer soybean and CLI in winter. This reflects the higher productivity of the crops (9.1%) and the improved chemical, physical, and biological attributes of the soil (with the exception of...
