| 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. |

| Soil samples were collected from the top 7.5 cm of soil in a Strict Natural Reserve (SNR), a surrounding buffer zone, a cassava farm and matured plantations of Gmelina, teak, and pine, so as to determine if plantation establishment and intensive cultivation affect the density and diversity of soil mites. Altogether, 41 taxonomic groups of mites were identified. The diversity and densities of mites in within the SNR, the buffer zone and the Gmelina were more than the diversity and densities in the cassava farm, teak and pine plantations. Each plantation had its own unique community structure which was different from the community structure in the SNR plot. The SNR plot and Gmelina were dominated by detritivorous cryptostigmatid mites unlike teak and pine... |

| 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 which soil properties drives structural diversity. Thirty-eight morphotypes of Collembola were recorded in this study, 11 belonging to the edaphic eco-morphological group,... |

| The objective of this work was to evaluate the density, dynamics and vertical distribution of a Hrabeiella periglandulata population in a forest soil at Brno, Czech Republic. From December 2003 to November 2004, two plots covered by mixed stands and two covered by coniferous stands were sampled monthly. Six soil cores per plot were taken down to 15 cm and subdivided into layers, which were subjected to wet funnel extraction. Missing in one of the coniferous stands H. periglandulata was abundant in the mixed stand with the highest soil pH. In this stand, monthly sampling continued until November 2005, with three additional samplings up to January 2007. Mean annual density was 2,672±1,534 individuals m-2. Population dynamics differed from those reported from... |

| 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: 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... |

| 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... |

| 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 reproduction rates of earthworms ( Eisenia andrei ) and springtails ( Folsomia candida ) through standardized ecotoxicological tests. The tests used a tropical soil representative of Brazil, classified as Entisol ( Neossolo Quartzarênico órtico típico )... |

| The mesofauna has an important function in the soil and it is represented mainly by Acari Oribatida and Collembola. We report the first data on the density and diversity of the soil mesofauna in Benjamin Constant, Amazonas State, Brazil. The following systems were evaluated: primary forest, secondary forest, agroforestry system, cultivated areas and pastures. A total of 101 samples were collected 100 m apart from each other and specimens were collected by using Berlese-Tullgren method. The highest density was registered in secondary forest (29,776 specimens.m-2). Acari Oribatida was the dominant group (7.072 specimens.m-2) in the pasture, suggesting that mites show higher capacity of adaptation to disturbed environments and/or due to the presence of... |

| Minhocas são conhecidas por diminuir a densidade aparente e aumentar a porosidade do solo, misturar a matéria orgânica e proporcionar a agregação das partículas do solo. Dessa forma, podem ser utilizadas como indicadoras da qualidade e saúde dos solos, inclusive em sistemas silvipastoris. Assim, a finalidade deste estudo foi examinar a presença e a distribuição de minhocas, comparando uma pastagem arborizada (SSP) com Grevillea robusta plantada em renques curvilíneos com uma pastagem não-arborizada (PNA). A amostragem, em seis áreas (cinco na SSP e uma na PNA), foi realizada no mês de outubro de 2005 em Cianorte, Paraná, Brasil. As amostras (n=162) foram coletadas em três pontos distribuídos ao longo de transectos perpendiculares aos renques das árvores... |

| 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 (LUSs): native forest (NF), Eucalyptus plantation (EP), pasture (PA), integrated crop-livestock (ICL), and no tillage (NT). Samples were collected to determine soil properties, and pitfall traps were set in the... |

| Soil fauna is a key control of the decomposition rate of leaf litter, yet its interactions with litter quality and the soil environment remain elusive. We conducted a litter decomposition experiment across different topographic levels within the landscape replicated in two rainforest sites providing natural gradients in soil fertility to test the hypothesis that low nutrient availability in litter and soil increases the strength of fauna control over litter decomposition. We crossed these data with a large dataset of 44 variables characterizing the biotic and abiotic microenvironment of each sampling point and found that microbe-driven carbon (C) and nitrogen (N) losses from leaf litter were 10.1 and 17.9% lower, respectively, in the nutrient-poorest site,... |
