A new genus and species of Schizogyniidae (Acari: Mesostigmata: Celaenopsoidea), Euroschizogynium calvum gen. nov. and sp. nov., associated with Scarites terricola Bonelli, 1813 (Coleoptera: Carabidae) is described from Ukraine, representing the first record of the family from the Palaearctic. Fusura civica Valle & Fox, 1966 is moved out of the Schizogyniidae and placed into the Megacelaenopsid...

BACKGROUND Additions to the list of Carabidae known for Nevada, USA and carabid beetles found in the Great Basin National Park, NV are reported with notes on ecology and identification resources. NEW INFORMATION For 79 species of carabids, we present 57 new state records, two state records previously reported in online resources, one confirmation of a previous questionable record for the stat...

Genetic differentiation was studied among populations of the salt marsh beetle Pogonus littoralis (Coleoptera: Carabidae), comparing Atlantic and Mediterranean populations over a large part of its range. The genetic structure of this highly mobile beetle was investigated by studying allozyme polymorphism at nine enzyme loci in 13 populations. Mediterranean P. littoralis were highly significantl...

Museum specimens from the late 19th and early 20th centuries were surveyed for the single nucleotide polymorphism identified previously and used to diagnose populations of the federally threatened Northeastern Beach Tiger Beetle Cicindela d. dorsalis (Coleoptera: Carabidae). Widespread polymorphism was revealed throughout the historical range of this species, suggesting a relatively recent anth...

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...
