Earthworms in grass lawns and native Atlantic Forest fragments at Embrapa Forestry, Colombo, Paraná state, Brazil.

Earthworms are important soil biological indicators, but there is relatively little information on their communities in peri-urban soils and land uses in the subtropics. In the present paper, we describe earthworm occurrence and relationships with soil biological, chemical and physical attributes in grass lawns and native Atlantic Forest fragments in the Curitiba metropolitan area, using different sampling methods: quantitative handsorting, formalin extraction and qualitative sampling. Overall, 785 individuals, of six families and 12 species were found, four of which were native (Glossoscolex embrapaensis, Fimoscolex nivae, Urobenus brasiliensis and Ocnerodrilidae sp.

Four new large Glossoscolex (Clitellata: Glossoscolecidae) earthworms from Brazil.

Four new species of earthworms in the genus Glossoscolex (Clitellata: Glossoscolecidae), one belonging to the truncatus (Glossoscolex anaclaudiae sp. nov.) and the others to the giganteus (Glossoscolex itatiaiaensis sp.

New earthworm species of Glossoscolex Leuckart, 1835 and Fimoscolex Michaelsen, 1900 (Clitellata: Glossoscolecidae) from southeastern Brazil.

Ten new species of earthworms (Crassiclitellata: Glossoscolecidae), belonging to the genera Glossoscolex and Fimoscolex are described from material collected in the Atlantic Forest biome in the mountains of southeastern Brazil in the states of São Paulo, Rio de Janeiro and Minas Gerais. Two of them are in Glosssoscolex, i.e.

Soil macrofauna communities in Brazilian land-use systems.

Background: Soil animal communities include more than 40 higher-order taxa, representing over 23% of all described species. These animals have a wide range of feeding sources and contribute to several important soil functions and ecosystem services. Although many studies have assessed macroinvertebrate communities in Brazil, few of them have been published in journals and even fewer have made the data openly available for consultation and further use.

Urban green areas as earthworm species maintainers in Curitiba, Paraná, Brazil.

Urban green areas can have a high impact on soil fauna due the environmental changes caused by human activities. This work aimed to assess earthworm populations in urban sites in the city of Curitiba, Paraná, Brazil. Earthworms were sampled in two urban sites: the Campus Ecoville of the Universidade Positivo and the Casa Verde space and in two land use systems (Grass Lawn and Native Vegetation), in the summer of 2018 and 2019 and winter of 2019.

Earthworm communities in long-term no-tillage systems and secondary forest fragments in Paraná, Southern Brazil.

The area destined for agricultural production in Paraná state in Brazil is ~6 million hectares, of which 79% are under no-tillage systems (NTS) that can positively affect earthworm populations. Furthermore, earthworm abundance and richness can be valuable soil quality. This study assessed earthworm communities in long-term no-tillage sites (NTS) and nearby secondary Atlantic Forest (SF) fragments.

Earthworm richness in no-tillage farming systems and riparian forests in Southern and Southeastern Brazil.

No-tillage (NT) is a soil conservation management practice that can sustain important earthworm populations due the maintenance of soil cover and absence of soil disturbance. Sites with NT can also support native earthworm species, but few studies have identified the earthworms collected under NT. Therefore, the present study evaluated earthworm diversity in 14 sites under NT and seven with riparian forest (RF) in Atlantic Forest located in Rolândia, Cambé, Toledo (Paraná), Coxilha, Sarandi (Rio Grande do Sul) and Itaí (São Paulo).

Pesticides in a case study on no-tillage farming systems and surrounding forest patches in Brazil.

With the growing global concern on pesticide management, the relationship between its environmental recalcitrance, food security and human health has never been more relevant. Pesticides residues are known to cause significant environmental contamination. Here, we present a case study on long-term no-tillage farming systems in Brazil, where Glyphosate (GLY) has been applied for more than 35 years.
