“…The results suggest that the orange orchards were more favorable to beetle species of forest fragment origin. This conclusion supports Thiele's (1977), who suggested that carabids in agricultural areas are remnants of the original forest fauna, but may also indicate a high probability of movement of individuals between the habitats (Kajak & Lukasiewicz, 1994). Likewise, not only the high similarity coefficient for the forest fragment and Table 1.…”

-The objective of this study was to determined species composition and community structure of Carabidae and Staphylinidae in fi ve areas of forest fragment and soybean/corn crops or orange orchard, from December 2004 to May 2007. Beetles were captured in pitfall traps distributed along two parallel transects of 200 m in length, placed across crop land/forest boundary fragment, with 100 m each. The Shannon-Wiener diversity and evenness indexes and Morisita similarity index were calculated. The carabids Abaris basistriatus Chaudoir, Calosoma granulatum Perty, Megacephala brasiliensis Kirby, Odontochila nodicornis (Dejean) and Selenophorus seriatoporus Putzeys. are dominant and are widely distributed in northeastern São Paulo state, Brazil. Point-scale species diversity was greatest at the transition between forest fragment and cultivated area. The carabid and staphylinid communities of the forest fragment were more similar to the community of orange orchard than that of soybean/corn crops.

“…While it would be of interest to study the variability of populations of rare species of ground beetle and those species that require protection, it would be equally rewarding to study the characteristics of common species of this family, which have a wide range and high degree of ecological flexibility (Brygadyrenko & Fedorchenko, 2008;Brygadyrenko & Slynko, 2015). One of the most abundant species in the ecosystems of almost the entire territory of Europe is Pterostichus melanarius (Illiger, 1798) (Thiele, 1977;Sharova, 1981;Den Boer, 1985;Kryzhanovskij et al, 1995;Hurka, 1996;Irmler, 2003).…”

“…Until now it has been considered that P. melanarius consumes practically all species of invertebrate animals, even those over twice their weight (Thiele, 1977;Pollet & Desender, 1985;Currie & Digweed, 1996;Thomas et al, 2008). Invertebrates that contain in their body poorly studied poisonous compounds form an exception to this dietary pattern (Symondson, 1997).…”

We examined polymorphism in an urban population of the ground beetle Pterostichus melanarius (Illiger, 1798) in forest plantations on the outskirts of Dnipropetrovsk (Ukraine). We took measurements for 130 males and 95 females according to 14 metric, 10 non-metric parameters and 10 indices. According to 13 out of the 14 metric parameters (except for the length of the flight wings) P. melanarius showed a significant sexual dimorphism. The female specimens showed a normal distribution in body length and the males showed a significant positive excess. The 10 most significant body proportions of the ground beetles showed much lower sexual differences (0.26±0.86%) compared to linear measurements (6.56±0.96%). Females and males are practically isomorphic: when one metric parameter decreases, another decreases proportionally. Statistically significant differences between males and females were registered only for the ratio of elytra to length of prothorax, width of elytra to maximum width of prothorax and length of elytra to their width. A highly significant excess was registered in 6 out of 10 assessments of body proportions for females and 5 out of 10 for males. The coefficient of variation is minimal for body proportions and is maximal for metric parameters, which proves the existence of isomorphic differences between P. melanarius males and females. Out of 10 non-metric parameters a statistically significant sexual dimorphism (P=0.01) was registered only for the shape of the front edge of the labrum (males mostly have a slightly concave, and females a strongly concave front edge of the labrum). Using PCA analysis it was established that 45.2% of the morphological variability of the studied population depends upon the individuals' sex: the whole complex of metric parameters (length and width of head, prothorax, elytra and parts of head, body height) taken together synchronically varies among individuals of different sex. More or less defined groups (morphotypes) were not found among the studied population of P. melanarius. The normal distribution of individuals in the studied population for a range of characteristics was altered by the impact of significant asymmetry or excess in certain features or ratios of metric characteristics. The data obtained can form the basis for monitoring the condition of P. melanarius populations, the individuals of which accumulate a large amount of toxins in conditions of anthropogenic impact.Key words: variability in populations; body size; sexual dimorphism; Pterostichus melanarius; ground beetle.

“…Carabids are generalists in crops and in natural habitats (Thiele, 1977;French and Elliott, 1999;Fournier and Loreau, 1999). The cluster analysis showed that A. basistriata did not show a preference for a specific habitat in either experimental area, being considered a generalist with respect to habitat preference (Figures 2 and 3).…”

The present study had as objective determine the diversity and abundance of adults Carabidae and Staphylinidae in two areas, constituted by forest fragment and soybean/corn crops under conventional tillage and no-tillage systems and to analyze the distribution and preference of those beetles for the habitat. The beetles were sampled with 48 pitfall traps. In both experimental areas, two parallel transects of pitfall traps were installed. Each transect had 100 m in the crop and 100 m in the forest fragment. Four traps were close to each other (1 m) in the edge between the crop and the forest fragment, the other traps were installed each 10 m. The obtained data were submitted to the faunistic analysis and the preference of the species by habitat was obtained by cluster analysis. The results demonstrated that the type of crop system (conventional tillage or no-tillage) might have influenced the diversity of species of Carabidae and Staphylinidae. The cluster analysis evidenced that the carabids may prefer a specific habitat. In the present study, the distribution of carabids and staphylinids in the three habitats showed that these beetles have potential to be dispersed at great distances inside the crop.Key words: ground beetles, rove beetles, no-tillage systems, forest fragment, edge.Diversidade e preferência de habitat de Carabidae e Staphylinidae (Coleoptera) em dois agroecossistemas ResumoEste estudo teve como objetivo determinar a diversidade e abundância de adultos de Carabidae e Staphylinidae em duas áreas, constituídas por fragmentos florestais e culturas de soja/milho sob sistemas de plantio convencional e direto, e analisar a distribuição e a preferência desses insetos para o habitat. Os besouros foram amostrados com o uso de 48 armadilhas de solo do tipo Pitfall. Em ambas as áreas experimentais, foram instalados dois transectos paralelos de armadilhas; cada transecto teve 100 m na culturas e 100 m no fragmento florestal. Na borda entre a cultura e o fragmento de floresta foram instaladas quatro armadilhas, que ficaram distantes entre si por 1 m e as outras armadilhas, a cada 10 m. Os dados obtidos foram submetidos à análise faunística e a preferência das espécies para o habitat foi obtida pela análise cluster. Pelos resultados, observa-se que o tipo de sistema de cultivo (convencional ou plantio direto) pode ter influenciado a diversidade de espécies de Carabidae e Staphylinidae. A análise de cluster evidenciou que os carabídeos tiveram preferência por um habitat específico. Neste estudo, a distribuição de carabídeos e estafilinídeos nos três habitats mostraram que estes besouros têm potencial para se dispersarem em grandes distâncias no interior da cultura.Palavras-chave: Carabídeos, estafilinídeos, sistemas de plantio direto, fragmento florestal, borda.
