Cím:Ground-dwelling arthropods as biodiversity indicators in maize agroecosystems of Northern Italy / Francesco Lami, Giovanni Burgio, Serena Magagnoli, Daniele Sommaggio, Roland Horváth, Dávid D. Nagy, Antonio Masetti
Dátum:2023
ISSN:1470-160X
Megjegyzések:Reliable monitoring of arthropod diversity in a given agroecosystem is essential for the conservation of the related ecosystem services, such as biological control. The often daunting complexity of arthropod collection and identification, however, highlights the need for surrogate taxa that can be easily sampled and be representative of a number of other taxa in term of diversity, general community features and specific composition. In this study, we used pitfall traps to sample three ground-dwelling arthropod taxa important as biocontrol agents (ground beetles, rove beetles and spiders) in 9 conventionally managed maize agroecosystems of Northern Italy over the course of two years, with the goal of characterizing their assemblages and evaluating their reciprocal potential as indicators of activity density, species richness, community turnover and species co-occurrence. Although dominated by few generalist species, sampled arthropod communities were relatively species-rich, and included the first Italian record of the spider Zelotes metellus (Roewer) (Araneae: Gnaphosidae). Ground beetles as a group were confirmed as promising indicators for the species richness and community composition turnover of rove beetles and spiders. Additionally, several abundant arthropod species acted as indicators of the species richness of their respective groups, and the ground beetle Pterostichus macer (Marsham) also worked as an indicator of overall rove beetle activity density. While the co-occurrence of individual arthropod species was limited for the studied taxa, a few species such as the ground beetle Parophonus maculicornis (Duftschmid) did show promise as species-specific bioindicators. Our results could be useful in improving the monitoring and management of these important natural enemies in maize-growing regions.

Cím:Urban individuals of three rove beetle species are not more exploratory or risk-taking than rural conspecifics / Tibor Magura, Roland Horváth, Szabolcs Mizser, Mária Tóth, Dávid D. Nagy, Réka Csicsek, Emőke Balla, Gábor L. Lövei

Megjegyzések:Urbanization is creating changes in environmental and habitat conditions, as well as creating disturbance and threats to urban-associated species. Some traits, such as high exploratory and risk-taking behavior, are beneficial to allow colonization of urban habitats and coping with urbanization-derived pressures. In this study the exploratory and risk-taking behavior of rural and urban individuals of three forest-associated rove beetle species were tested during their main reproductive period by five frequently used behavioral measures. Individuals of all studied species were similarly ranked by all behavioral measures, indicating that the studied rove beetles responded consistently in the different contexts. However, the behavior of beetles was consistent over time for all/most studied species only by using two measures of exploratory behavior. These provide evidence for the existence of the exploratory dimension of personality in rove beetles. We found a higher exploratory behavior in males than females in Ocypus nitens which can be explained by the active searching of males for mating partners. There were no urbanization-related differences in the exploratory behavior of individuals, suggesting that behavioral changes (being more exploratory) may not yield additional fitness benefits in these rove beetle species with good dispersal capacity.

Cím:Are there personality differences between rural vs. urban-living individuals of a specialist ground beetle, Carabus convexus? / Tibor Magura, Szabolcs Mizser, Roland Horváth, Dávid D. Nagy, Mária Tóth, Réka Csicsek, Gábor L. Lövei
Dátum:2021
ISSN:2075-4450
Megjegyzések:The world-wide, rapid urbanization is leading to substantial changes in environmental and habitat conditions. These changes, as well as disturbances accompanying urbanization have considerable effects at various levels of the biological organization on wildlife. Understanding behavioral responses to such changes is essential for identifying which organisms may successfully adapt to the altered conditions. In this study, individuals of a forest specialist ground beetle, Carabus convexus, from rural and urban forest patches were tested for their exploratory and risk-taking behavior. Beetles responded consistently in the different contexts; furthermore, by behaving consistently over time, demonstrated that they had personalities. Agglomerative cluster analysis identified two groups of behavioral traits: the exploratory and the risk-taking dimension of personality. Urban females were significantly more exploratory than urban males which can be an adaptation to find high quality food needed to mature eggs in urban habitats, as well as to select favorable microsites for oviposition. Moreover, urban females and males showed more risk-taking behavior than rural females. Urban beetles with more risk-taking behavior may be better able to cope with frequent urbanization-driven disturbance events.

Cím:Differences in life history traits in rural vs. urban populations of a specialist ground beetle, Carabus convexus / Tibor Magura, Szabolcs Mizser, Roland Horváth, Dávid D. Nagy, Mária Tóth, Réka Csicsek, Gábor L. Lövei
Dátum:2021

Megjegyzések:Urbanization is increasing worldwide and causes substantial changes in environmental parameters, generating various kinds of stress on arthropods, with several harmful consequences. We examined a forest specialist ground beetle, Carabus convexus, in forested habitats to evaluate the changes in four important life history traits between rural and urban populations. Analyzing beetles from the overwintered cohort in their first breeding season, we found no significant differences in body length or body mass between the rural and urban individuals. Body condition, judged by fat reserve scores, was similarly poor in both habitats, indicating that beetles were not able to accumulate substantial fat reserves at either habitat. Females with ripe eggs in their ovaries were first captured at the same time in both areas. The number of ripe eggs, however, was significantly higher in females of the low-density urban population (6.13 eggs/female) than in those of the high-density rural population (4.14 eggs/female), indicating density-dependent fecundity. Altered environmental and habitat conditions by urbanization, however, seemed to cause high mortality during egg hatching and/or larval development, preventing the growth of the urban population to the level of rural one.

Cím:Arthropod assemblages and functional responses along an urbanization gradient: A trait-based multi-taxa approach / Nagy Dávid D., Magura Tibor, Horváth Roland, Debnár Zsuzsanna, Tóthmérész Béla
Dátum:2018
ISSN:1618-8667
Megjegyzések:Urbanization causes considerable alteration across a wide range of ecosystem functions at regional and global scales. These changes could be key drivers of habitat stability and ecosystem services in urban greenspaces. The aim of this study was to test the influence of urbanization on taxonomic and functional diversities of arthropods of different trophic levels. We collected predator spiders, polyphagous rove beetles, and decomposer woodlice along a rural-suburban-urban gradient by litter sifting. Neither the taxonomic, nor the functional diversity (Rao's quadratic entropy) using a morphological trait (body size) and ecological traits (habitat affinity, humidity preference, and disturbance sensitivity) of the spiders were significantly different along the urbanization gradient. For rove beetles, taxonomic diversity was significantly higher in rural sites compared to suburban and urban ones, while functional diversity did not differ significantly between sites. Both the taxonomic and the functional diversities of woodlice were significantly higher in the rural sites than in the suburban or urban sites. Detrended canonical correspondence analysis also showed that urbanization did not cause considerably changes in composition of spider assemblages, while rove beetle and woodlouse assemblages showed clear separation between rural and urban sites. This study pointed out that trophic levels may be a crucial driver of the responses to urbanization. Our results suggest that urbanization has a less harmful effect on predator spiders, as they can easily recolonize the managed urban greenspaces. Contrarily, recolonization of arthropods at lower trophic levels (rove beetles and woodlice) into the urban habitats is considerably restricted.

Cím:Spider assemblages in floodplain forests along an urbanization gradient / Tajthi Bence, Horváth Roland, Mizser Szabolcs, Nagy D. D., Tóthmérész B.
Dátum:2017
ISSN:1585-8553 1588-2756
Megjegyzések:Urban areas have been growing radically worldwide, causing considerable changes in biodiversity of natural habitats. In floodplain forests, we studied the effects of urbanization on ground-dwelling spider assemblages along a rural?suburban?urban gradient in Hungary. We tested three traditional hypotheses (intermediate disturbance hypothesis, habitat specialist hypothesis and hygrophilous species hypothesis) and two novel expectations (shade-preferring species hypothesis, and disturbance sensitive species hypothesis) on spiders. We found that the total number of species was higher in the suburban habitat than in rural and urban ones, supporting the intermediate disturbance hypothesis. We found a decrease in the species richness of forest specialist and shade-preferring species along the urbanization gradient. We found that the number of hygrophilous and disturbance sensitive species was the lowest in the urban habitat. The spider assemblages of the rural and suburban habitats were clearly separated from the assemblages of urban habitats. Based on our findings we emphasize that low and moderate intensity of forest management contributes to the preservation of the local species richness in floodplain forests.

Megjegyzések:There are contrasting opinions on the use of prescribed burning management in European grasslands. On the onehand, prescribed burning can be effectively used for the management of open landscapes, controlling dominantspecies, reducing accumulated litter or decreasingwildfire risk. On the other hand burning can have a detrimentalimpact on grassland biodiversity by supporting competitor grasses and by threatening several rare and endangeredspecies, especially arthropods.We studied the effects of prescribed burning in alkaline grasslands of highconservation interest. Our aim was to test whether dormant-season prescribed burning can be an alternativeconservation measure in these grasslands. We selected six sites in East-Hungary: in three sites, a prescribedfire was applied in November 2011, while three sites remained unburnt. We studied the effects of burning onsoil characteristics, plant biomass and on the composition of vegetation and arthropod assemblages (isopods, spiders,ground beetles and rove beetles). Soil pH, organic matter, potassium and phosphorous did not change, butsoluble salt content increased significantly in the burnt sites. Prescribed burning had several positive effects fromthe nature conservation viewpoint. Shannon diversity and the number of flowering shoots were higher, and thecover of the dominant grass Festuca pseudovinawas lower in the burnt sites. Graminoid biomasswas lower,whiletotal, green and forb biomasswere higher in the burnt plots compared to the control. The key finding of our study was that prescribed burning did not decrease the abundance and diversity of arthropod taxa. Species-level analysesshowed that out of the most abundant invertebrate species, 10 were not affected, 1 was negatively and 1 waspositively affected by burning. Moreover, our results suggest that prescribed burning leaving unburnt patchescan be a viable management tool in open landscapes, because it supports plant diversity and does not threatenarthropods.
