| ABSTRACT Dihoplotermes, a previously monotypic genus, is now composed of two species. Dihoplotermes taurus sp. nov., a new Termitinae termite species, is illustrated and described based on morphological characters from soldiers, workers, and imago. The new species is distinguished from Dihoplotermes inusitatus Araujo by having a spine-like protuberance with blunt apex on the postmentum, the presence of a spine on the gizzard and the absence of dimorphic soldiers. Furthermore, the internal morphological characteristics of a Dihoplotermes worker are described for the first time. Both internal and external morphological characters were used to improve the characterization of the species. |

| O trabalho teve como objetivo avaliar a densidade e diversidade da macrofauna invertebrada do solo de um sistema de produção envolvendo a rotação lavoura e pecuária, sob plantio direto. O trabalho foi conduzido no Município de Dourados, Estado do Mato Grosso do Sul, num LATOSSOLO VERMELHO Distroférrico típico, em parcelas com monocultivo e preparo convencional do solo, sistema integrado lavoura/pecuária em plantio direto e pastagem contínua, e um fragmento de vegetação nativa. As avaliações foram realizadas em quatro épocas distintas: janeiro/2002, junho/2002, janeiro/2003 e julho/2003, conforme o método recomendado pelo programa “Tropical Soil Biology and Fertility” (TSBF). Os sistemas com menor interferência antrópica apresentaram maior abundância e... |

| ABSTRACT: The successive application of pig slurry to pastures is a common practice in southern Brazil, serving as a method of waste disposal as well as an important alternative to chemical fertilization. Although there are economic benefits to the use of manure as fertilizer, it may be associated with environmental hazards and cause changes to composition and activity of soil fauna. This study aimed to study the effects of pig slurry on the soil biota of pastures. Composition and biological activity of pastures where manure was applied successively for 2 years (A2) and 14 years (A14) were evaluated, and native forest (NF) was analyzed as a reference area. Successive application of pig slurry to the soil changed its biological characteristics according to... |

| ABSTRACT: Elephant grass and castor cake when combined can make a promising organic fertilizer. However, castor cake contains potentially toxic chemicals, such as ricin and ricinine. To test potential effects of these chemicals, compost piles of elephant grass ( Pennisetum purpureum Schum.) with castor cake were prepared with different C:N ratios (T1 = 40, T2 = 30, T3 = 20; T4 = 30 [control, elephant grass + crotalaria]) to evaluate colonization by edaphic fauna and any suppressive effects of castor cake. Soil organisms were collected with Berlese-Tullgren funnels. There were temporal differences between the treatments, and the epigeous fauna was mainly represented by members of the Acari and Entomobryomorpha. Elapsed time is the major factor in... |

| ABSTRACT Hog raising generates a large amount of residues that is commonly discarded into the soil as fertilizer even with environmental risks. In this context, the aim of this study was to assess the application effects of different doses of swine wastewater (SW) associated with mineral fertilization on the abundance and diversity of organisms of soil meso- and macrofauna in two soybean crops. Treatments consisted of four doses (0, 100, 200, and 300 m3 ha−1) of SW with or without mineral fertilization in two soybean crop, totaling 24 experimental units. Soil meso- and macrofauna were sampled using pitfall traps installed at each plot. Samples were sorted and the organisms were separated and identified. The highest abundances were found between groups of... |

| We analysed species abundance and composition during one year of sampling at Itapuã State Park, a conservation unit in the State of Rio Grande do Sul, southern Brazil. Samples were collected monthly from May 2003 to April 2004 along a 4 km forest trail divided in three transects along the slopes of a small hill. Terrestrial isopods were hand searched by three people for 40 minutes at two sampling sites along each transect, summing 240 minutes of sampling effort per transect per month. Six species distributed in six families were found. The collector curve stabilised when half the samples were taken, demonstrating sampling sufficiency: analytical estimates did not predict more species to be found in the trail. Atlantoscia floridana (van Name, 1940) was... |

| Estudo sobre a fauna do solo e decomposicao da serapinheira feito em tres diferentes ecossistemas na Amazonia central: (1) floresta primaria (FLO), (2) floresta secundaria (SEC), e (3) duas parcelas de cultivo misto (POA, POC). As pesquisas incluiram a avaliacao da producao e estoque de serapilheira, parametros do solo, fatores microclimaticos, abundancia e biomassa da fauna do solo, determinacao da respiracao no solo e biomassa microbiana, medidas das taxas de respiracao dos componenetes da fauna, e analises de micronutrientes. Apesar das diferencas observadas entre as areas de estudo, foi observado que em todas elas o sistema de decomposicao da serapilheira foi controlado pela macrofauna, e que, em todos os sistemas de cultivo estudados, as condicoes... |

| A fauna de invertebrados do solo representa os animais que vivem no solo e dependem deste para sobrevivência. Eles podem ser organismos microscópicos (o que não podemos enxergar a olho nu), como colêmbolos e ácaros de solo; ou macroscópicos como insetos (besouros, formigas, baratas, tesourinhas, paquinhas), miriápodes (embuás ou piolho-de-cobra, lacraia), aracnídeos (aranhas, escorpiões), nematóides, minhocas e moluscos gastrópodes. O solo é formado por diferentes camadas e isso também determina a distribuição dos invertebrados ao longo desta estratificação. Assim, existem os invertebrados que vivem sobre o solo (folhiço) e aqueles que escavam galerias (rasas ou profundas) vivendo em camadas em que a matéria orgânica decomposta está misturada às partículas... |
