However, the response of particular species to anthropogenic pressures is variable and, therefore, some species may perform better (winners) and others worse (losers) in the face of landscape homogenization. Our main objective was to understand which plant and pollinator species were the most vulnerable to this landscape disturbance. To evaluate this, we used data on pollinator and plant abundance in 20 study sites located along a gradient of landscape heterogeneity (i.e. diversity of land-cover layers at 500 m and 1 km radius surrounding the study sites) across Mallorca Island (western Mediterranean Basin). For 46 pollinator species (hymenopterans and dipterans) and 162 plant species, we collected functional traits (either by direct measurements or from literature) that reflect the ability of species to adapt to changing environments, and related their abundance to their traits along a gradient of landscape heterogeneity. Landscape heterogeneity influenced the study groups at different scales, affecting Diptera at a smaller scale than Hymenoptera and plants. Although the number of species was not influenced by landscape heterogeneity, the abundance of species was. An increase in landscape heterogeneity favored the abundance of social Hymenoptera compared to solitary ones. The abundance of Hymenoptera that nest in the ground or in cavities increased with landscape heterogeneity, while the abundance of builders decreased. Besides, increasing landscape heterogeneity enhanced the abundance of small and medium sized Hymenoptera, whereas the abundance of large Hymenoptera remained stable along the heterogeneity gradient. Landscape heterogeneity also favored the abundance of parasitoid and anthophilous Diptera. Regarding plants, we found that more heterogeneous landscapes also held a higher abundance of zygomorphic flowers. Understanding the ‘winners’ and ‘losers’ in the face of landscape changes may help prevent and anticipate the effects of global change on the pollination service.</div></div>","PeriodicalId":8708,"journal":{"name":"Basic and Applied Ecology","volume":"87 ","pages":"Pages 55-65"},"PeriodicalIF":3.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144331004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Along the rivers Emscher and Lippe, 16 sites were studied. Reduced management’ was characterized by sowing native species and mowing twice annually with cutting removal, while intensive management’ included frequent mowing and mulching. Sites were investigated where reduced management was established recently or several years ago. Reduced management increased species richness and altered community composition across all groups compared to intensive management. Plant species richness increased by 5.7, general arthropods by 4.8, and epigean carabids by 0.7. No significant differences were observed between short- and long-term implementation. Ruderal and stress-tolerant plant species dominated vegetation in intensively managed sites, while reduced sites supported more specialized feeding types across insect species and floodplain-specific carabids. Larger, univoltine arthropods were more common in reduced sites. Sowing native grassland species and changing the management from intensive to reduced mowing can increase biodiversity and favor specialist species. This effect is achieved within a short time after implementation and remains effective in the long term. Conversion from intensive to reduced management is, therefore, an important strategy for increasing biodiversity and resilience of grasslands in urban floodplains.</div></div>","PeriodicalId":8708,"journal":{"name":"Basic and Applied Ecology","volume":"87 ","pages":"Pages 100-109"},"PeriodicalIF":3.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144633521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To better understand the biodiversity value of green roofs, it is crucial to understand what type of green roofs best support native bees and the attributes that affect this. A mix of active and passive sampling methods were used to survey bees from 20 green roofs in Melbourne during summer 2019/20. Local and landscape attributes of the green roofs were collected in the field or via spatial analysis using GIS. A total of 20 bee species utilising green roofs were identified. Generalised linear models (GLM) and hierarchical modelling of species communities (HMSC) found that impervious ground cover within the surrounding landscape was a strong negative predictor for bee abundance and richness. Further, increased foraging resources on the green roofs had positive effects on bee abundance and richness. Height above ground had a negative effect on some bee species, but their body size was not an influencing factor. These findings are important for green roof planting design and suggest that roofs lower in height that contain a diversity of floral resources are most suited to support diverse native bee communities.</div></div>","PeriodicalId":8708,"journal":{"name":"Basic and Applied Ecology","volume":"87 ","pages":"Pages 110-119"},"PeriodicalIF":3.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144633522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Citizen science (CS) initiatives therefore may provide valuable data and may complement data collected by professionals. Photo-apps equipped with automated taxonomic identification based on artificial intelligence play a central role in CS, at least for well distinguishable organisms such as the majority of butterfly species. In this study, we analysed butterfly (Papilionoidea) observations collected with three different photo-apps (i.e. <em>Blühendes Österreich, iNaturalist, observation.org</em>). We compared these data with observations from the <em>Global Biodiversity Information Facility</em> (GBIF). For this purpose, we classified each butterfly species according to its detectability and attractiveness, as well as its ecology and behaviour. Our results show that the observations obtained from the three photo-apps mainly cover mobile, conspicuous and easy-to-identify species, while the rare and sedentary specialist species and species that are difficult to distinguish from other taxa are underrepresented. Furthermore, the observations collected differ significantly between the three apps, and <em>Blühendes Österreich</em> particularly lacks inconspicuous butterfly species. However, a detailed regional analysis of user performance revealed that the differences among the three apps largely stem from Austrian-wide difference in app usage and less to user specific biases in recording. Within single habitats, amateurs and semi-professional users performed similarly in recording. In consequence, a combination of the data from the various apps might provide a largely realistic picture. However, most rare and ecologically demanding species seem to be covered inadequately. Thus, the recording of such species must be continued by experts to obtain a comprehensive picture of regional biodiversity.</div></div>","PeriodicalId":8708,"journal":{"name":"Basic and Applied Ecology","volume":"87 ","pages":"Pages 46-54"},"PeriodicalIF":3.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144320826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we characterized bacterial communities in rhizosphere of alpine plants (28 species) and bulk soil at 13 sites of three alpine grassland types along the longitudinal gradient (from 82.5°E to 93.8°E) in China. Our results showed that climate and soil properties (e.g. mean annual precipitation, soil pH, and organic matter content), as well as bacterial taxonomic diversity in these two soil origins, changed along the longitudinal gradient. Total OTUs richness, Shannon index, and generalist richness of bacterial communities in the bulk soil increased along longitude, apparently due to the higher organic matter content and lower available potassium content. On the contrary, Shannon index in the rhizosphere decreased along longitude and was not related with any environmental factor. The dissimilarity in bacterial communities between paired samples was positively related with the differences in longitude and environmental factors (mean annual precipitation and soil pH in particular) for the two soil origins. There was a positive relationship between bacterial community dissimilarity among rhizosphere samples and the phylogenetic distance of co-occurring plant species in the individual sites of different alpine grassland types, suggesting phylogenetic conversation in plant-bacteria interactions under field conditions. Our findings suggest that the differential responses of bacterial communities in the rhizosphere versus bulk soil to abiotic and biotic factors may underlie their opposite longitudinal patterns, which highlights the necessity of integrating biogeographic and phylogenetic approaches in exploring plant-soil bacterial associations.</div></div>","PeriodicalId":8708,"journal":{"name":"Basic and Applied Ecology","volume":"86 ","pages":"Pages 11-20"},"PeriodicalIF":3.0,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143891591","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we evaluated the suitability of both tissue- and preservative-based DNA metabarcoding approaches for potential use in large-scale forest insect monitoring initiatives with a focus on beetle communities. For this purpose, we investigated the contents of pitfall (Barber) traps and corresponding cross-window traps for the presence of Coleoptera species. We also compared the performance of three common preservative liquids in terms of species and DNA preservation and determined the optimal time interval for trap replacement. To assess how well the investigated forest beetle community can actually be represented by metabarcoding, we identified ground beetles (Carabidae) of each Barber trap sample using (a) morphological identification; (b) DNA metabarcoding of the homogenised tissues; and (c) DNA metabarcoding of the preservative liquids used in the traps. Finally, we evaluated the influence of the number of DNA extraction and PCR replicates on taxon detection. Even though our study was limited to a single location and peak season, we succeeded in detecting the DNA of 389 mostly plausible beetle species across a total of 54 samples. Effects of preservative liquids were small, although more species were captured by ethanol-filled traps. We further observed an increase in detected beetle species with increasing length of trapping intervals.

Twenty individuals of each group were collected at two locations differing in environmental and anthropogenic pressures: one regularly used for recreational fishing and surrounded by agriculture in the Rhine Valley and one consisting of research ponds in the Palatinate Forest with restricted public access. Wing morphology and symmetry were assessed via computer-vision by comparing several cell shape and position dependent variables as well as wing size and number of cells and junctions using the recently developed software WingAnalogy.

In these individuals, the cell shape asymmetry was more pronounced in the distal part of the wing than in the proximal part. Mating males had lower body weight (-5%) and smaller wings (-3%) compared to chasing males at both locations. Our results challenge the general theory that stress-induced lower body weight and higher asymmetry diminish short-term mating success. Instead, they underscore the ecological importance of population-specific factors, like female availability or male-male competition, and environmental conditions that shape mating dynamics.

However, the role of aquatic prey in the diet varied between predator groups and hunting strategies. Riparian web-building spiders, especially horizontal web-builders such as <em>Tetragnatha</em>, showed the highest proportion of aquatic insects in their diet (70 %).
