“…The dendrogram shows the dissimilarity of this to the other areas studied (Figure 1). According to Southwood et al (1979), insect diversity increases with the successional habitat age and decreases slightly at climax. Thus, our results suggest that the area of BT without castor oil plants is in succession.…”

SUMMARYThe results of ecological restoration techniques can be monitored through biological indicators of soil quality such as the leaf litter arthropod fauna. This study aimed to determine the immediate effect of brushwood transposition transferred from an area of native vegetation to a disturbed area, on the leaf litter arthropod fauna in a degraded cerrado area. The arthropod fauna of four areas was compared: a degraded area with signal grass, two experimental brushwood transposition areas, with and without castor oil plants, and an area of native cerrado. In total, 7,660 individuals belonging to 23 taxa were sampled. Acari and Collembola were the most abundant taxa in all studied areas, followed by Coleoptera, Diptera, Hemiptera, Hymenoptera, and Symphyla. The brushwood transposition area without castor oil plants had the lowest abundance and dominance and the highest diversity of all areas, providing evidence of changes in the soil community. Conversely, the results showed that the presence of castor oil plants hampered early succession, negatively affecting ecological restoration in this area.Index terms: ecological restoration, signal grass, mesofauna, Acari, Collembola.(1) Extracted from the first author's Scientific Initiation submitted to the Department of Biological Sciences, UNESP -Univ Estadual Paulista, Campus

“…Originally it was not much employed, perhaps because its calculation was quite tedious without a computer [46] (even with the help of Williams's nomograms [21,70]). Nowadays, a is often used to compare communities in terms of species richness, by eliminating the effect of sample size [8,12,13,45,46,50]. In that context, it has shown a strong positive correlation with habitat heterogeneity (expressed in terms of its effect on the fauna) [8,45].…”

OATAO is an open access repository that collects the work of Toulouse researchers and makes it freely available over the web where possible. b s t r a c tWe have developed an individual-based evolving predator-prey ecosystem simulation that integrates, for the first time, a complex individual behaviour model, an evolutionary mechanism and a speciation process, at an acceptable computational cost. In this article, we analyse the species abundance patterns observed in the communities generated by our simulation, based on Fisher's logseries. We propose a rigorous methodology for testing abundance data against the logseries. We show that our simulation produces coherent results, in terms of relative species abundance, when compared to classical ecological patterns. Some preliminary results are also provided about how our simulation is supporting ecological field results.

“…Devido à maior penetração de luz no sub-bosque das florestas secundárias em sucessão, em razão de uma maior abertura do dossel, há uma densidade maior de folhas e um aumento na produção de folhas jovens (Aide & Zimmermann 1990;Aide 1992). Southwood et al 1979e Brown & Hyman 1986 observaram que a diversidade de plantas e insetos herbívoros era maior nos estágios iniciais de sucessão vegetal, decaindo continuamente para os estágios mais avançados, principalmente no sub-bosque. Em Vila Velha, a maior riqueza de espécies de Coleoptera nas áreas florestais secundárias em estágio inicial a intermediário de sucessão vegetal também deve ser produto das condições acima indicadas, corroborando o observado por Southwood et al 1979e Brown & Hyman 1986.…”

“…Vários trabalhos relacionaram a fauna de Coleoptera ao ambiente florestal, enfocando a importância da diversidade, estrutura e arquitetura vegetais (Southwood et al 1979;Lawton 1983;Lawton et al 1998;Humphrey et al 1999;Wagner 2000), na diversidade deste grupo de insetos. Em decorrência destas características, vários estudos (Hutcheson 1990, Humphrey et al 1999, Hutcheson & Jones 1999) têm encontrado elementos que apontam os Coleoptera como possíveis indicadores de diversidade e de ambiente, principalmente na determinação de níveis de conservação de áreas florestadas.…”

ABSTRACT. The inventory diversity of Coleoptera (Insecta) of an anthropized landscape in the Biome Araucaria. The species richness, taxonomic composition, rare species, and taxonomic constancy at family level were studied in communities of Coleoptera in Vila Velha, Ponta Grossa, Paraná, as part of PROVIVE project. The data were gathered through malaise traps in the understory stratum of five sites with different floristic conditions product of anthropogenic effects, from September/1999 to August/2000. The 52 weeks sampling in the five sites produced 10,822 specimens of 1,659 species. All areas present high species richness and high diversity as indicated by various indices. The area in advanced condition of vegetation succession was less rich than ones in early/middle stage. According to different species richness estimators, the number of observed species could be increased by 22-123% if more time colleting effort had been made. The early successional stage areas were richer in rare species (singletons, doubletons and uniques) than the more preserved ones. In the five areas there were a taxonomic constancy among the richest families (Curculionidae, Chrysomelidae, Cerambycidae, Staphylinidae, Mordelidae, Elateridae, Scarabaeidae, Coccinellidae and Tenebrionidae) involving 60% of the total species as observed with the specimens abundance. If the existence of this pattern is confirmed, it will be easier and faster to study Coleoptera communities and soon apply this order as a forest environmental indicator taxon.
