Cím:	Diversity and assemblage filtering in ground-dwelling spiders (Araneae) along an urbanisation gradient in Denmark / Gábor L. Lövei, Roland Horváth, Zoltán Elek, Tibor Magura
Dátum:	2019
ISSN:	1083-8155 1573-1642
Megjegyzések:	We studied the effects on spiders of a three-step rural-urban urbanisation gradient near a Danish town embedded in a historically forested landscape. Using pitfall traps set in forested habitat patches, we collected a total of 3075 adult spiders of 80 species; the habitats under different degrees of urbanisation had 45?47 species. We found support for Gray's Increasing Disturbance Hypothesis: the species richness trap?1 was significantly higher in the rural habitat than in any other one, and decreased from the rural forest to forest fragments dominated by non-native trees in the urban park. The number of forest specialist species also decreased along the urbanisation gradient. Neither the presence of generalists nor light-preferring species increased under more urbanised conditions, but web builders and hygrophilous species were more species-rich in the rural habitat than elsewhere. Using indicator values, we identified Coelotes atropos, Walckenaeria corniculans, Walckenaeria cucullata, and Pachygnatha listeri as species linked to the rural and suburban habitats; Trochosa terricola, Saaristoa abnormis, Robertus lividus as characteristic of the rural habitat; and Gongylidium rufipes and Diplocephalus latifrons as urban habitat specialists.

Cím:	Urbanization-driven changes in litter decomposition in forest patches revealed by the teabag method / Tibor Magura. Roland Horváth, Szabolcs Mizser, Mária Tóth. Gábor L. Lövei
Dátum:	2025
ISSN:	1083-8155 1573-1642
Megjegyzések:	Urbanization, a rapid and powerful component of anthropogenic global change, substantially impacts all levels of biological organization, from individuals to ecosystems. Among regulatory ecosystem services, litter decomposition plays a critical role in soil nutrient supply and the maintenance of properly functioning soil. Urbanization generally negatively affects biodiversity, environmental and habitat characteristics, all of which significantly influence decomposition processes. However, relatively few studies, some with methodological limitations, have assessed the impact of urbanization on the decomposition. To address this gap, we conducted a standardized two-year study to investigate the decomposition of rooibos teabag-litters incubated for 3, 6, 9, and 12 months in soils of forested habitats with similar forest associations, soil types, and histories but with different urbanization level. Decomposition in both the rural and urban habitats was more intense in the first year, characterized by warmer-than-average temperatures and average precipitation, than in the second one year, with average temperatures and below-average precipitation. Decomposition was significantly faster in urban forest patches (average 42% mass loss) than in rural forest stands (average 36% mass loss) after 6 months of incubation in both years. This difference is likely attributed to higher soil temperature in urban habitats, which stimulates microbial and enzymatic activity. Faster decomposition in urban habitats can lead to profound effects on ecosystem structure, functions, services, and biodiversity, and even can release stored carbon back into the atmosphere, contributing to global climate change. Therefore, a comprehensive urban habitat management is needed to mitigate these negative effects.
