To compare carabid assemblages from transgenic Bt- and isogenic maize in Hungary, we used pitfall traps in an experiment (30x30 m plots, arranged alternately in 6 replications), during the growing season of maize during 2001—2003. We captured altogether 44,103 individuals of 58 species. The most common species in our sampling were Calatlzus ambiguus, Doliclzus halensis, Harpalus distinguendus, H rufipes, Poecilus sericeus and Treclius quadristriatus. The same species dominated both in the Bt- and in the isogenic maize plots. Under our test conditions (plot size and 3 years of sampling), no significant differences were found either in the structural characteristics (number of individuals, number of species and diversity), activity density or seasonal activity patterns ofthe dominant species.

Urbanisation Gradient

The seasonal activity of six carabid species (Nebria brevicollis, Carabus nemoralis, C. hortensis, C. coriaceus, Pterostichus melanarius and Abax parallelepipedus) was studied along an urbanisation gradient (rural forest – suburban forest – forest fragments in urban park) in Sorø, Denmark, during April–October 2004 and 2005.Two groups were identified: 1) Species with constant seasonality, in which seasonal activity profiles did not differ along the gradient (C. hortensis, C. coriaceus, and A. parallelepipedus); 2) Species with flexible seasonality,with remarkable differences along the gradient and between the years (C. nemoralis, N. brevicollis and P. melanarius). In four out of six studied species, 2005 was less favourable than 2004. Spring activity in the urban habitat started earlier than in the suburban or forested ones. A better understanding of urban green infrastructures in biodiversity assessments may need the study of seasonality in order to distinguish whether the bioindicator’s responses are to habitat quality or stochastic seasonal events.

<p>Anthropogenic impact on the population of ground beetles leads to a change in their numbers, structure of dominance, density, species composition, spectrum of life forms. This makes the beetles Carabidae a convenient and informative bioindicator of the ecological state of biocenoses. The material for this work was the Carabidae collections conducted in June-August 2016-2017 in the park zone of different regions of Barnaul, differing in location, area, hydrological regime, vegetation cover, purpose and anthropogenic load. When processing the material, the quantitative, species and generic composition of the carabidae was determined, calculations were made for such indicators as the Berger-Parker dominance index, the Shannon species diversity index (Hs), and the Jacquard species similarity index. The fauna (Coleoptera, Carabidae) of the park zone of Barnaul is represented by 55 species belonging to 20 genera. The dominant group is represented by species belonging to steppe, forest and polyzonal groups. Forest-steppe species of ground beetles as dominants have not been identified in any of the investigated territories. The greatest variety of ecological groups was noted on the territory of the Yubileyny рark, which is explained by the presence of zones with various microclimatic conditions, the presence of a birch grove that flows through the park with the Pivovarka River, and a wide log in the park. Registered species belong to eight groups of life forms belonging to two classes - zoophagous and myxophytophagous. On the numerical and species abundance, zoophages predominate. The spectrum of life forms corresponds to the zonal spectrum characteristic of the forest-steppe zone.</p><p> </p>

Activity Cycles

A study of seasonal activity cycles in a pre-urban society, examined through the lens of an early medieval Welsh case study. It examines how these cycles shaped patterns of power and habitual activity, defining spaces and structuring lives. Its multidisciplinary, comparative analysis identifies focal zones and challenges commonly applied interpretations.
