“…The arthropod community was dominated by Formicidae, Coleoptera and Aranae in terms of abundance. The dominance of Formicidae and Coleoptera has been indicated as a general trait of ground dwelling assemblages in the Mediterranean and dessert assemblages (Doblas-Miranda et al, 2007). Even in Mediterranean agrosystems these groups dominates in the soil arthropod fauna (Morris & Campos, 1999;Santos et al, 2007).…”

“…Strong seasonality is a feature of most ecosystems, particularly in Mediterranean habitats, where the seasonal fluctuations of temperature and rainfall create marked pulses of productivity and animal activity (Blondel & Aronson, 1999). The seasonal and annual variability of the assemblage has potentially important implications on community dynamics in the study systems, since the changes in species composition and trophic structure of soil invertebrate assemblages may affect species interactions and food web dynamics over time (Doblas-Miranda et al, 2007).…”

The study of soil arthropods can provide valuable information how ecosystems respond to different management practices. The objective was to assess the total abundance, richness, and composition of epiedaphic arthropods in different agrosystems from southwestern Spain. Six sites with different agricultural uses were selected: olive grove, vineyards, olive grove with vineyards, wheat fields, fallows (150-300 m long), and abandoned vineyards. Crops were managed in extensive. Field margins were used as reference habitats. At the seven sites a total of 30 pitfall traps were arranged in a 10 × 3 grid. Traps were arranged to short (SD, 1 m), medium (MD, 6 m) and large (LD, 11 m) distance to the field margins in the middle of selected plots. Pitfall traps captured a total of 11,992 edaphic arthropods belonging to 11 different taxa. Soil fauna was numerically dominated by Formicidae (26.60%), Coleoptera (19.77%), and Aranae (16.76%). The higher number of soil arthropods were captured in the field margins followed by the abandoned vineyard. Significant differences were found between sites for total abundance, and zones. However, no significant differences for total abundance were found between months (April-July). Richness and diversity was highest in field margins and abandoned vineyards. Significant differences were found for these variables between sites. Our results suggest that agricultural intensification affects soil arthropods in Tierra de Barros area, a taxonomic group with an important role in the functioning of agricultural ecosystems.Additional key words: abundance; agrosystems; diversity; field margins. Resumen Abundancia de artrópodos epigeos en parcelas con diferentes cultivosEl estudio de los artrópodos puede aportar información de interés de cómo los ecosistemas responden a las diferentes prácticas de manejo del suelo. El objetivo de este estudio fue determinar la abundancia, la riqueza y la composición de artrópodos epigeos en diferentes agrosistemas del suroeste de España. Se seleccionaron seis parcelas con diferentes usos agrícolas: olivar, viñedo, plantación mixta de viñedo-olivar, cereal, barbecho y viñedo abandonado, utilizándose los linderos como sistemas de referencia. En cada parcela se colocaron 30 trampas de caída en una cuadrícula de 10 × 3, de modo que cada línea de trampas quedó colocada a una distancia corta (SD, 1 m), media (MD, 6 m) o grande (LD, 11 m) de los linderos. Se capturaron un total de 11.992 artrópodos edáficos, pertenecientes a 11 taxa diferentes. Numéricamente la fauna del suelo estaba dominada por Formicidae (26,60%), Coleoptera (19,77%) y Aranae (16,76%). El mayor número de artrópodos se capturó en los linderos y en la viña abandonada, encontrándose diferencias significativas en la abundancia entre las diferentes parcelas y las zonas donde se ubicaron las líneas de trampas. Sin embargo, no se encontraron diferencias entre los distintos meses estudiados (abril-julio). La riqueza y la diversidad fue mayor en los linderos y en la viña abandonada, encontrándose diferenc...

“…The difference in the pattern of macroarthropod richness and abundance between the rainy and dry seasons may be related to seasonal variation in some climatic elements of the Caatinga, such as rainfall and temperature, keeping in mind the effects of these factors on resource availability (e.g., organic matter), composition, and community dynamics (Mooney, 1981;Doblas-Miranda et al, 2007;Hernandéz, 2007;Vasconcellos et al, 2010a).

In arid and semiarid environments, seasonality usually exerts a strong influence on the composition and dynamics of the soil community. The soil macroarthropods were studied in a Caatinga forest located in the Reserva Particular do Patrimônio Natural (RPPN) Fazenda Almas, São José dos Cordeiros, Paraíba, Brazil. Samples were collected during the dry and rainy seasons following the method proposed by the Tropical Soil Biology and Fertility Program (TSBF), with minor modifications. At each station, 15 soil blocks (20 × 20 × 30 cm: 12 L) were extracted and divided into three layers: A (0-10 cm), B (10-20 cm), and C (20-30 cm). In the rainy and dry seasons 1,306 ± 543(se) and 458 ± 212 ind.m -2 macroarthropods were found, respectively, with 35 and 18 respective taxa recorded. The abundance of individuals and taxa were significantly higher in the rainy season. Isoptera (57.8%) was the most abundant taxon, followed by Hymenoptera: Formicidae (17.2%), Coleoptera larvae (7.3%), and Araneae (3.5%). In the rainy season, abundance in layer A (576 ± 138 ind.m -2 ) was significantly higher than that of layer C (117 ± 64 ind.m ). There was also no difference between the layer B and C abundances. In the dry season, abundance in layer B (232 ± 120 ind.m -2 ) was not significantly different compared to layer A (182 ± 129 ind.m -2 ), but was significantly higher than abundance in layer C (44 ± 35 ind.m -2 ). During the rainy season, layer A (34 taxa) was significantly richer in taxa than layers B (19 taxa) and C (11 taxa). On the other hand, during the dry season the richness of layers A (12 taxa) and B (12 taxa) was equal, but significantly higher than that of layer C (6 taxa). Richness of taxa and abundance were positively correlated with soil organic matter and negatively correlated with soil temperature. The community of soil macroarthropods in the area of Caatinga studied has taxonomic and functional structures that are relatively complex and is therefore likely to exert an influence on ecosystem productivity due to its physical effects on soil profile and necromass fragmentation, as occurs in other arid and semiarid ecosystems throughout the world.Keywords: semiarid, soil fauna, environmental variables, insects.

Abstract:Longstanding observations suggest that dissolved materials are lost from fresh litter through leaching, but the role of soil fauna in controlling this process has been poorly documented. In this study, a litterbag experiment employing litterbags with different mesh sizes (3 mm to permit soil fauna access and 0.04 mm to exclude fauna access) was conducted in three habitats (arid valley, ecotone and subalpine forest) with changes in climate and vegetation types to evaluate the effects of soil fauna on the concentrations of dissolved organic carbon (DOC) and total dissolved nitrogen (TDN) during the first year of decomposition. The results showed that the individual density and community abundance of soil fauna greatly varied among these habitats, but Prostigmata, Isotomidae and Oribatida were the dominant soil invertebrates. At the end of the experiment, the mass remaining of foliar litter ranged from 58% for shrub litter to 77% for birch litter, and the DOC and TDN concentrations decreased to 54%-85% and increased to 34%-269%, respectively, when soil fauna were not present. The effects of soil fauna on the concentrations of both DOC and TDN in foliar litter were greater in the subalpine forest (wetter but colder) during the winter and in the arid valley (warmer but drier) during the growing season, and this effect was positively correlated with water content. Moreover, the effects of fauna on DOC and TDN concentrations were greater for high-quality litter and were related to the C/N ratio. These results suggest that water, rather than temperature, dominates how fauna affect the release of dissolved substances from fresh litter.
