Cím:A meta-analysis indicates reduced predation pressure with increasing urbanization / Eötvös Csaba Béla, Magura Tibor, Lövei Gábor L.
Dátum:2018
ISSN:0169-2046
Megjegyzések:Urbanization is one of the most important global trends which causes habitat reduction and alteration which are, in turn, the main reasons for the reduced structural and functional diversity in urbanized environments. Predation is one of the most important ecological functions because of its community-structuring effects. According to previous studies effects of urbanization on predation rates appear inconsistent. Predator species are vulnerable to habitat alteration and loss caused by urbanization, therefore, we hypothesised that predation rate would decrease along the rural-urban gradient. To clarify the impact of urbanization on predation, we performed a meta-analysis on predation rates in rural vs. urban areas using published data of 25 studies. Predation rates on taxa other than birds were underrepresented, preventing an overall evaluation. Reported predation rates on birds were significantly higher in rural than in urban habitats.

Cím:Predictors of conservation value of Turkish cemeteries: A case study using orchids / Löki Viktor, Molnár V. Attila, Süveges Kristóf, Heimeier Helmut, Takács Attila, Nagy Timea, Fekete Réka, Lovas-Kiss Ádám, Karel C. A. J. Kreutz, Sramkó Gábor, Tökölyi Jácint

Megjegyzések:In the face of worldwide habitat loss, the role of human-shaped habitats in conserving biodiversity is becoming increasingly important. Due to their special cultural role, cemeteries can preserve parts of the native vegetation when the surrounding landscape becomes degraded. However, these special refuges are threatened by human encroachment and changing management practices. The aim of this study was to understand how urbanization affects the conservation value of cemeteries, indicated by orchids as flagship species for biodiversity conservation. We analyzed species richness, abundance and the presence of threatened orchid taxa in cemeteries from 631 differently sized Turkish settlements along an urban-rural gradient. To understand driving patterns determining the conservation value, we performed detailed characterization of 288 cemeteries in terms of woody vegetation (tree cover and proportion of native trees) and overall structure (age, density and type of graves). Conservation value was highest in rural cemeteries. Rural cemeteries were smaller, contained more traditional and less densely situated graves, but their woody vegetation was similar to urban cemeteries. The proportion of native trees was positively related to species richness, abundance and presence of threatened orchid taxa, after taking into account area, altitude and geographical location of cemeteries. In addition, cemetery structure (age and density of graves) predicted species richness. Our results indicate that urbanization and modern changes in human activity have a strong impact on the conservation value of Turkish cemeteries. Practices maintaining traditional burial habits and environment-friendly management of cemeteries deserve more moral and financial support.

Cím:A species-level comparison of occurrence patterns in carabids along an urbanisation gradient / Tibor Magura, Béla Tóthmérész, Tivadar Molnár
Dátum:2008
ISSN:0169-2046
Megjegyzések:The activity-density pattern of frequent carabid species was studied using pitfall traps in forest patches along an urbanisation gradient defined in terms of the ratio of the built-up area to the natural habitat. We predicted that the activity-density of the forest specialist carabid species should decrease from rural sites to the more altered urban ones. We also predicted, that there is no unique pattern for the generalist species, because the activity-density pattern is controlled by their autecological characteristics in a complex interaction with the environmental variables, and urbanisation/disturbance level. Moreover, we identified the environmental factors responsible for the observed variation in carabid activity-density. As predicted, the activity-density of two forest specialist species (Carabus convexus, Pterostichus oblongopunctatus) decreased significantly from rural sites to urban ones. The activity-density of the generalist species, Amara convexior, was higher in the heavily disturbed urban sites. The generalist species, Ophonus nitidulus, was significantly more abundant in the rural sites. The other five frequent generalist species (Notiophilus rufipes, Pterostichus melanarius, Harpalus luteicornis, Pterostichus niger, Stomis pumicatus) showed no significant changes in activity-density along the gradient. The two open-habitat species (Anisodactylus nemorivagus, Bembidion lampros) also showed no significant changes in activity-density along the gradient. Canonical correspondence analysis highlighted that the variation in the activity-density of the studied species was related to the following environmental factors: ground temperature, air temperature, relative humidity, leaf-litter cover, cover of decaying wood material, herbs, shrubs, and to the amount of prey items.

Cím:Responses of carabid beetles to urbanization in Transylvania (Romania) / Béla Tóthmérész, István Máthé, Enikő Balázs, Tibor Magura
Dátum:2011
Megjegyzések:To investigate the impact of urbanization on carabid beetles samples were taken over two years using pitfall traps along a rural-urban forest gradient representing increasing human disturbance in and nearby the city of Sfântu Gheorghe (Romania). We predicted that total number of species should decrease, whereas number of opportunistic and matrix species should increase towards the urban end of the gradient. Both the overall species richness and the number of individuals were significantly the highest in the suburban area followed by the rural area and the lowest in the urban area. These findings contradicted the increasing disturbance hypothesis; the number of species did not decrease by the increasing disturbance. The proportion of the forest specialist individuals and species significantly decreased from the rural towards the urban area, supporting the habitat specialist hypothesis. An opposite pattern was observed in species richness of the generalist carabids, supporting the opportunistic species hypothesis. Both the proportion of matrix species and their density were significantly higher in the urban area, supporting the matrix species hypothesis. Our findings also highlighted that overall diversity is not an appropriate indicator; species with different habitat affinities should be analysed separately to evaluate the real effect of urbanization
