Carabid beetles (Coleoptera, Carabidae) are one of the most studied soil groups in relation to heavy metal (HM) accumulation and use for bioindication of environmental pollution. Accumulation of Zn and Cu in carabid beetles was species-, sex- and trophic group-specific. No differences were found in HM contents between omnivorous and carnivorous species. The use of carabid beetles as indicators ...

Abstract In Western Norway, farmers have traditionally used fire as a management tool in coastal heathlands to enhance the fodder quality for livestock. Rotational prescribed burning increases landscape heterogeneity by creating mosaic of different regeneration stages heather. Ground beetle (Coleoptera: Carabidae) responses managed heathland already been studied, but less is known about other g...

Aim As one of the most diverse and economically important families on Earth, ground beetles (Carabidae) are viewed as a key barometer climate change. Recent meta-analyses provide equivocal evidence abundance changes terrestrial insects. Generalizations from traits (e.g., body size, diets, flights) insights into understanding community responses, but syntheses for Carabidae have not yet emerged....

ground beetles (family carabidae) with more than 40,000 described species worldwide are one of the most important generalist predators in agroecosystems. because of their habit of feeding on agricultural pests and weed seeds, in this study we tried to assess their biodiversity in agroecosystems of azadshahr region, eastern golestan province. samples were collected for some main crops, using pit...

Balticeler kerneggeri gen. nov. , sp. is described based on six fossil specimens preserved in Eocene Baltic amber and imaged using light microscopy X-ray micro-computed tomography. Based certain characters observed the species it considered a “middle grade” Carabidae, outside of large family Harpalinae (as possesses scrobal seta, lack which synapomorphy that subfamily), but possessing four syna...

Abstract Agricultural intensification has caused a simplification of agricultural landscapes, accompanied by increasing field sizes and reduction non-crop habitats. To mitigate negative impacts intensification, it is necessary to understand what extent different habitats contribute the maintenance biodiversity in agroecosystems. Here, we compared taxonomic diversity three beetle families among ...

Most transgenic corn seed is now treated with systemic neonicotinoid insecticides. To address potential direct nontarget effects of these combined technologies, 16 Carabidae species from 10 genera (Agonum, Amara, Anisodactylus, Bembidion, Chlaenius, Harpalus, Patrobus, Poecilus, Pterostichus, and Scarites) Þeld-collected from corn were directly exposed to Bacillus thuringiensis (Bt) Cry toxin-l...
