“…Among the natural enemies commonly found in agroecosystems are species that belong to the family Carabidae (Collins et al, 2003;Macleod et al, 2004), and Abaris basistriata is considered to be dominant in agroecosystems and natural and semi-natural habitats (Cividanes et al, 2009;Martins et al, 2009).…”

Abaris basistriata, a beetle species dominant in agroecosystems and natural habitats, may benefit from the establishment of nearby refuge areas or crop field centers. To confirm this hypothesis, we analyzed the spatial distribution of the species and verified the population dynamics of this predator in a soybean/corn rotation crop and a central refuge area. The 1-ha experimental area was divided in half by a range of herbaceous plants (2 m in width and 80 m in length). Beetle samples were collected using pitfall traps every fortnight during the in-season and every month during the off-season (a total of 27 sampling occurrences). Population fluctuation was analyzed by correlating the total number of specimens with plant phenology. We used multiple regression analysis with variable (stepwise) selection to examine the influence of meteorological factors on species occurrence. To determine the spatial distribution, data were analyzed using dispersion indices and probabilistic models based on the Coleoptera frequency distribution. Distribution visualization was assessed using a linear interpolation map. A total of 143 A. basistriata specimens were collected, with 83 from the soybean/corn area and 60 from the refuge area.Periods of large population size occurred during a season with high rainfall and high maximum and minimum temperatures. On the basis of the spatial distribution analysis of A. basistriata, it is likely that the beetles occur in an aggregate form, preferably in the refuge area.Index terms: Interpolation map; population fluctuation; refuge areas; soybean. RESUMOA espécie Abaris basistriata é dominante em agroecossistemas e habitats naturais, podendo ser beneficiada pela criação de áreas de refúgio próximas ou ao centro de culturas. Para confirmar essa hipótese, este estudo teve como objetivo analisar a distribuição espacial e verificar a dinâmica populacional desse predador em uma área de rotação soja e milho e uma área de refúgio central. A área experimental apresentava um hectare dividido ao meio por uma faixa de plantas herbáceas de dois metros de largura por 80 metros de comprimento. Os besouros foram coletados com armadilhas pitfall com amostragens quinzenais na safra e mensais na entressafra, totalizando 27 amostras. A flutuação populacional foi analisada e relacionada com o total de espécimes e as fases fenológicas das plantas. Utilizou-se análise de regressão múltipla com seleção de variáveis "stepwise", para verificar a influência dos fatores meteorológicos na ocorrência da espécie. Para determinar a distribuição espacial, os dados foram analisados por meio dos índices de dispersão e modelos probabilísticos, com base na distribuição de frequência dos coleópteros. A visualização da distribuição foi verificada por mapa de interpolação linear. Um total de 143 espécimes de A. basistriata foi coletado, sendo 83 na cultura de soja/milho e 60 na área de refúgio. Os períodos de elevada população ocorreram, durante a estação de alta precipitação pluvial, com temperatura mínima e máxima elevada. ...

“…A study carried out by Nunes et al (2008) showed that these organisms represented about 40% of the total of individuals in a forest under caatinga in the rainy season, being favored by dense litter. In turn, Martins et al (2009) found that more simplified environments favor the reduction of species of this group, mainly due to the alteration of the microclimate, since temperature and soil humidity are factors that regulate the distribution of these insects.…”

The vegetation physionomy and cover can show patterns of diversity and composition of the edaphic community, depending on the quantity and quality of litter in a specific habitat. The objective of this study was to evaluate the effect of the vegetation gradient formed by Graminoid Field (GRF), Cerrado Sensu Stricto (CSS), Cerradão (CRD) and Semideciduous Seasonal Forest (SSF) on density, diversity and composition of the edaphic fauna community in two seasons of the year, in the Sete Cidades National Park (Piauí state). For fauna sampling, a total of eight pitfall traps, distanced 10 m, were placed in each area in the central part of each system, where they remained for seven days. In the wet period, there was a tendency to increase the number of individuals as a function of the complexity of the vegetation formation, with the inverse occurring in the dry period. It was verified an environmental variation of the climatic factors temperature and humidity according to the vegetal formation, contributing to a heterogeneous distribution of the fauna. The GRF formation presented a significantly lower value of average richness only in the dry period. Regarding the variables of diversity and uniformity, they did not show drastic variations in relation to the vegetation gradient studied. The dominant groups in the vegetation gradient were Formicidae, Coleoptera, Aranae, Acari and Collembola, with reduction of the number of Coleoptera in the dry season. Principal component analysis (PCA) revealed greater differences in the composition of the communities between the vegetation formations for the rainy season. At this time, the formations SSF and CRD were associated to a greater diversity of invertebrates than CSS and GRF, demonstrating the influence of the vegetation complexity on the soil fauna community.Keywords: Savanna, seasonality, species diversity, soil invertebrates, successional stage. Fauna edáfica em um gradiente vegetacional no Parque Nacional de Sete Cidades ResumoA fisionomia e cobertura vegetal podem mostrar padrões de diversidade e composição da comunidade edáfica, em função da quantidade e qualidade da serapilheira em determinado habitat específico. O presente trabalho teve por objetivo avaliar o efeito do gradiente vegetacional formado por Campo Graminóide (CGR), Cerrado Sensu Stricto (CSS), Cerradão (CRD) e Floresta Estacional Semidecídua (FES) sobre a densidade, diversidade e composição da comunidade da fauna edáfica em duas épocas do ano do Parque Nacional de Sete Cidades (PI). Para amostragem da fauna foram colocadas um total de oito armadilhas do tipo Pit-fall, distanciadas por 10 m, em cada área na parte central de cada sistema, onde permaneceram por sete dias. No período úmido houve uma tendência a aumento do número de indivíduos conforme a complexidade da formação vegetal e o inverso ocorreu no período seco. Verificou-se uma variação ambiental dos fatores climáticos temperatura e umidade conforme a formação vegetal contribuindo para uma distribuição heterogênea da fauna. Apenas no período ...
