Megjegyzések:AimThe relationship between isoprenoid emission and hygrophily was investi-gated in woody plants of the Italian flora, which is representative of Europeandiversity. MethodsVolatile isoprenoids (isoprene and monoterpenes) were measured, ordata collected from the literature, for 154 species native or endemic to the Medi-terranean. The Ellenberg indicator value for moisture (EIVM) was used to describeplant hygrophily. Phylogenetic analysis was carried out at a broader taxonomic scaleon 128 species, and then refined on strong isoprene emitters (SalixandPopulusspecies) based on isoprene synthase gene sequences (IspS).ResultsIsoprene emitters were significantly more common and isoprene emis-sion was higher in hygrophilous EIVM classes, whereas monoterpene emitters weremore widespread and monoterpene emission was higher in xeric classes. However,when controlling for phylogeny, isoprene emission was not associated with EIVM,possibly due to the large presence of Salicaceae among hygrophilous isopreneemitters. Moreover, the distribution of isoprene emitters among EIVM classes wasnot related toIspS-based phylogenesis inPopulusandSalix, suggesting that thegene has not undergone evolution linked to ecological pressure. In contrast,the monoterpene emission pattern is independent of phylogeny, suggesting that theevolution of monoterpenes is associatedwith transitions to more xeric habitats.Main conclusionsOur results reveal an interesting ecological pattern linkingisoprenoids and water availability. We suggest that isoprene is a trait that: (1)evolved in plants adapted to high water availability; (2) is replaced by more effectiveprotection mechanisms, e.g. more stable isoprenoids, in plants adapting to morexeric environments; and (3) being strongly constrained by phylogeny, persists inSalicaceae adapted to more xeric environments

Cím:Only habitat specialists become smaller with advancing urbanization / Tibor Magura, Marco Ferrante, Gábor L. Lövei
Dátum:2020
ISSN:1466-822X
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.

Cím:Plants dispersed by a non-frugivorous migrant change throughout the annual cycle / Renáta Urgyán, Balázs A. Lukács, Réka Fekete, Attila Molnár V., András Nagy, Orsolya Vincze, Andy J. Green, Ádám Lovas-Kiss

Megjegyzések:Aim: Migratory waterfowl are important endozoochory vectors for a range of plants lacking fleshy fruits. Our aim was to study the critical question of how endozoochory rates change throughout the annual cycle, and how this relates to plant life-form and phenology. Location: Lake Velence, Hungary. Time period: 2017-2018. Major taxa studied: Mallard (Anas platyrhynchos), Angiospermae, Charophyta. Methods: We studied waterfowl endozoochory, quantifying seeds and other diaspores dispersed by mallards by collecting faecal samples monthly (ntotal = 670) at a Hungarian lake. We tested the germinability of all seeds recovered from the faecal samples. Main conclusions: We extracted 5,760 seeds representing 35 plant taxa from mallard faecal samples, and 40% of these seeds germinated successfully following gut passage. We found major differences between seasons in the species composition of the seeds recovered. The peak in species diversity and in abundance of terrestrial seeds coincided with the spring migration of mallards. Importantly, endozoochory was only strongly synchronized with seed production in submerged, but not in emergent or terrestrial plants, illustrating the potential for endozoochory of seeds ingested from the soil seed bank. Overall, our results suggest that endozoochory by migratory waterfowl is a strong and underestimated driver of plant distributions, and is likely to facilitate plant range shifts under climate change, and after introduction of alien species.

Cím:Climate and mating systems as drivers of global diversity of parental care in frogs / Balázs Vági, Zsolt Végvári, András Liker, Robert P. Freckleton, Tamás Székely
Dátum:2020
ISSN:1466-822X
Megjegyzések:Aim: Amphibians exhibit unusually diverse reproductive modes, including a wide array of parental care strategies. The evolutionary drivers of this diversity, however, remain unclear. Here, we investigate three major factors that might predict interspecific variation in parental care strategies: climate, intrasexual selection and social environment. We hypothesize that some forms of care evolved to cope with harsh conditions, such as dry or unpredictable habitats. We contrast this prediction with the hypothesis that parental roles have co-evolved with the social environment and mating systems. Location Global. Major taxa: studied Frogs and toads (Amphibia: Anura). Time period: Extant taxa that represent c. 220 Myr of evolutionary history. Methods: Using geographical and behavioural data for 971 species of frogs and toads that represent 45 anuran families, we quantified the global distribution of four forms of parenting separately for males and females: nest building, nest and/or tadpole attendance, carrying and nourishment. We used phylogenetic comparative analyses to investigate whether climate, social environment and mating systems predicted interspecific variation in parental care. Results: Our results showed that climatic effects contribute to parental care diversity: in cool and humid climates the males provide offspring attendance, whereas in predictable temperatures endotrophy occurs, whereby the female provides all nutrients for the offspring until metamorphosis. In addition, we found other associations between mating systems and forms of parental care: uniparental clutch attendance by males is present in species with territorial defence, whereas cooperative nest building co-occurs with sperm competition. The type of parental care is not associated with adult sex ratios. Main conclusions: No specific form of care is associated with hostile environments; in fact, some forms of care occur in beneficial conditions, whereas others are used independently from the climate. Instead, parenting diversity has co-evolved closely with mating systems in frogs.
