Cím:Only habitat specialists become smaller with advancing urbanization / Tibor Magura, Marco Ferrante, Gábor L. Lövei
Dátum:2020

Megjegyzések:Aim Urbanization profoundly changes environments, ecosystems and biodiversity. The urban heat island (UHI) effect represents one of the most consistent human-induced environmental change in urbanized areas. Recently, it was observed that the UHI causes community-wide shifts towards species with smaller body sizes in urban communities of ectotherms due to increased metabolic costs. We here assembled a large dataset of published data of geographically distant carabid communities collected along urbanization gradients to examine whether we could confirm this consistent change in body size distribution. Location Rural and urban forests at 11 northern temperate locations, spanning 25 latitudinal degrees. Time period 2002-2018. Major taxa studied Species of ground beetles (Coleoptera: Carabidae). Methods We evaluated size distribution changes using community-weighted mean body sizes of ground beetles collected from similarly vegetated rural and urban habitats between 2002 and 2018. We separately examined the UHI effect on the various sub-assemblages of the carabid community. Results When analysing the entire dataset, we could not detect any clear trend in the community body size mean, with urban communities showing similar values to those sampled in rural areas. However, the sub-assemblage of forest habitat specialists consistently displayed a significant shift towards smaller species from rural to urban habitats. The inconsistent trend at the community level was likely due to the influx into urban habitat fragments of non?specialist species. The UHI effect also had a significant influence but only on the forest specialist sub-assemblage. Main conclusions Our results indicated that forest-specialist species were most affected by the UHI as a powerful urbanization-related environmental filter, whereas this effect was not evident for the overall community. Urban management practices should aim to minimize the intensity of urbanization-related environmental filters such as the UHI, to enable habitat specialists to survive in habitat fragments under urbanized conditions.

Cím:Does urbanization decrease diversity in ground beetle (Carabidae) assemblages? / Tibor Magura, Gábor L. Lövei, Béla Tóthmérész
Dátum:2010
Megjegyzések:Aim We wanted to test whether urbanization has similar effects on biodiversity indifferent locations, comparing the responses of ground beetle (Coleoptera, Carabidae)assemblages with an urbanization gradient.We also wanted to see if urbanizationhad a homogenizing effect on ground beetle assemblages.Locations Nine forested temperate locations in Europe, Canada and Japan.Methods Published results of the Globenet Project were used. At all locations,three stages were identified: (1) a forested (rural) area, (2) a suburban area wherethe original forest was fragmented and isolated, and (3) remnants of the originalforest in urban parks. These habitats formed an urbanization series. Study arrangements(number and operation of traps) and methods (pitfall trapping) were identical,conforming to the Globenet protocol. Assemblage composition and diversitypatterns were evaluated.Diversity relationships were analysed by the Rényi diversityordering method considering all ground beetles and ? separately ? the forest specialistspecies. Taxonomic homogenization was examined by multivariate methodsusing assemblage similarities.Results Overall biodiversity (compared by species richness and diversity ordering)showed inconsistent trends by either urbanization intensity or by geographicposition.However, when only forest species were compared, diversity was higher inthe original rural (forested) areas than in urban forest fragments.Within-countrysimilarities of carabid assemblages were always higher than within-urbanizationstage similarities.Main conclusions Urbanization does not appear to cause a decrease in groundbeetle diversity per se. Forest species decline as urbanization intensifies but thistrend is masked by an influx of non-forest species. The rural faunas were moresimilar to the urban ones within the same location than similar urbanization stageswere to each other, indicating that urbanization did not homogenize the taxonomiccomposition of ground beetle faunas across the studied locations.
