Variations in Carabidae assemblages across the farmland habitats in relation to selected environmental variables including soil properties

Abstract

Variations in AbstractThe variations in ground beetles (Coleoptera: Carabidae) assemblages across the three types of farmland habitats, arable land, meadows and woody vegetation were studied in relation to vegetation cover structure, intensity of agrotechnical interventions and selected soil properties. Material was pitfall trapped in 2010 and 2011 on twelve sites of the agricultural landscape in the Prešov town and its near vicinity, Eastern Slovakia. A total of 14,763 ground beetle individuals were entrapped. Material collection resulted into 92 Carabidae species, with the following six species dominating: Poecilus cupreus, Pterostichus melanarius, Pseudoophonus rufipes, Brachinus crepitans, Anchomenus dorsalis and Poecilus versicolor. Studied habitats differed significantly in the number of entrapped individuals, activity abundance as well as representation of the carabids according to their habitat preferences and ability to fly. However, no significant distinction was observed in the diversity, evenness neither dominance. The most significant environmental variables affecting Carabidae assemblages species variability were soil moisture and herb layer 0-20 cm. Another best variables selected by the forward selection were intensity of agrotechnical interventions, humus content and shrub vegetation. The other from selected soil properties seem to have just secondary meaning for the adult carabids. Environmental variables have the strongest effect on the habitat specialists, whereas ground beetles without special requirements to the habitat quality seem to be affected by the studied environmental variables just little.Keywords: arable land, ground beetles, meadows, non-crop habitats, soil moisture Ďalšími významnými premennými, ktoré vplývajú na kompozíciu spoločenstva sú intenzita agrotechnických zásahov, obsah pôdneho humusu a krovinová vegetácia. Ostatné zo sledovaných pôdnych vlastností majú na dospelé jedince bystrušiek len sekudárny vplyv. Rovnako, environmentálne premenné najvýraznejšie ovplyvňujú habitatových špecialistov, zatiaľ čo druhy bystrušiek bez vyhranených nárokov na podmienky prostredia sú ovplyvnené uvedenými faktormi len málo.Kľúčové slová: bystruškovité, mimoprodukčné habitaty, orná pôda, pôdna vlhkosť, trvalo trávne porasty

A DNA barcode library for ground beetles of Germany: the genus Pterostichus Bonelli, 1810 and allied taxa (Insecta, Coleoptera, Carabidae)

“…1). Due to the fact that various species of this genus represent important and highly abundant elements of the carabid fauna of many habitats world-wide (e.g., Igondová and Majzlan 2015;Hong et al 2017;Baranová et al 2018), they have been intensively studied in the past, for example their general ecology (e.g., Rushton et al 1990;Fournier and Loreau 2001;Allema et al 2012;Brigić et al 2014), feeding strategies (e.g., Symondson et al 2000;Langan et al 2001;Dinis et al 2016), and zoogeography/phylogeography (e.g., Lagisz et al 2010;Schmidt et al 2012;Sasakawa et al 2017).…”

Effect of global climate change on the distribution of Anchomenus dorsalis (Coleoptera, Carabidae) in Europe

“…In Poland, A. dorsalis is the most abundant species living in field margins (Sklodowski 2006(Sklodowski , 2014Sklodowski and Garbalinska 2011;Bennewicz and Barczak 2020). In Eastern Slovakia (Baranova et al 2018), A. dorsalis is dominant on agricultural landscape sites.…”

Distribution of ground beetles of the genus Bembidion (Coleoptera, Carabidae) in the agricultural landscape in Northwestern Russia

“…In Canada, small Bembidion quadrimaculatum Linnaeus, 1761 were more likely to prey on the Sitona lineatus Linnaeus, 1758 eggs, than larger Pterostichus melanarius (Illiger, 1798) ground beetles (Vankosky et al, 2011). The significant number of researches was done regarding the abundance of ground beetles in agrocenoses (Shurovenkov, 1977;Honěk, 1997;Eyre, Luff, 2004;Guseva, Koval, 2015;Baranová et al, 2018;Putchkov, 2018;Vician et al, 2018;. However, the distribution of these predators across agricultural landscapes, including different fields and adjacent habitats, is understudied, since it is desirable to have a temporally and spatially developed experimental crop rotation surrounded by natural biocenoses.…”
