Scavenging, an important ecological function performed by scavenger assemblages, stands as a significant force shaping ecosystems. Using biodiversity partitioning, we assess the relative contribution of multiple scales (i.e., within and among individual carcasses, species and habitats) to the richness and Shannon diversity of vertebrate scavenger communities consuming anthropogenic food subsidies (i.e. livestock carrion) in central Argentina. We further evaluate the potential effect of carcass and habitat characteristics (including human impact) on the richness, abundance and diversity of vertebrate scavengers. A total of 31 carcasses, 22 of cow and nine of sheep, were monitored using remote cameras in cropland and natural habitats, recording consumption by 10 vertebrate species (four birds and six mammals). 50 % of scavenger species were observed at carcass level (<em>α<sub>1</sub></em> = 4.94 species), a contribution lower than expected by chance. While the turnover of species among carcasses (<em>β<sub>1</sub></em> diversity) significantly contributed (40 %) to regional richness (γ diversity), turnover of species between carrion types and habitats (β<sub>2</sub> diversity) contributed a smaller fraction (10 %). Partitioning of Shannon diversity showed similar patterns to richness. Scavenger abundance increased during spring and was positively influenced by carcass weight; furthermore, carcasses in croplands supported less abundance that those located in natural habitats. Aligning with the theory of carrion unpredictability in maintaining biodiversity, our results suggest that scavenger species replacement (turnover) at human-mediated carcasses scattered in the field plays a significant role in shaping vertebrate scavenger assemblages.</div></div>","PeriodicalId":8708,"journal":{"name":"Basic and Applied Ecology","volume":"83 ","pages":"Pages 64-72"},"PeriodicalIF":3.0,"publicationDate":"2025-01-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143098328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we examined how plant communities were affected by management intensity and landscape context in two European wine-growing regions. We established four plots within one inter-row and three transects in two neighbouring inter-rows and one undervine row in each of 70 paired vineyards (organic versus conventional farming) along a gradient of proportion of semi-natural habitats in the landscape. We analysed how alpha, beta and gamma diversity and plant species community composition at the vineyard scale responded to farming system, disturbance frequency, and semi-natural habitats. We found a positive impact of organic farming on alpha and gamma diversity and a significant influence of farming and transect type on species community composition. Besides farming system, disturbance frequency (tillage and mulching) reduced alpha diversity but increased beta diversity in the transects of both wine-growing regions. This difference could be attributed to the establishment of different plant communities of vineyards managed with higher or lower mulching and/or tillage intensity. At the landscape scale, higher proximity to and higher proportion of semi-natural habitats increased plant alpha and gamma diversity. Both landscape variables also explained significant variance of the plant community composition. Conservation of farmland biodiversity in vineyards should focus on supporting low-intensity diversified management operations and increasing shares of semi-natural habitats in the landscape.</div></div>","PeriodicalId":8708,"journal":{"name":"Basic and Applied Ecology","volume":"83 ","pages":"Pages 98-108"},"PeriodicalIF":3.0,"publicationDate":"2025-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143259639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used samples collected over an entire flowering season in 24 xeric pine savannas in north-central Florida, USA and evaluated the effects of plant availability and pollinator competitor pool on three aspects of trophic specialization: taxonomic specialization (pollinator selection of plant species), phylogenetic specialization (pollinator selection of plant phylogenetic lineages), and functional specialization (pollinator selection of plant functional traits). Our results show that flowering resources and the pools of pollinator competitors both influence pollinator trophic specialization. Individual pollinators reacted to higher pollinator richness by interacting with more flowering plants (i.e.,taxonomically generalist), underscoring the vulnerability of pollination systems to pollinator extinctions (i.e., pollinators visit fewer plant species when there are fewer insect competitors present). Pollinators were more specialized in communities containing many conspecific pollinators, possibly reflecting pollinator preferences. Finally, in more diverse flowering plant assemblages, pollinators were taxonomic specialists in flower visitation but phylogenetic and functional generalists, providing pollination services across diverse plant assemblages.</div></div>","PeriodicalId":8708,"journal":{"name":"Basic and Applied Ecology","volume":"83 ","pages":"Pages 118-127"},"PeriodicalIF":3.0,"publicationDate":"2025-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143373019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We employed the Plant Functional Types (PFTs) classification system, which is particularly well-suited for the unique characteristics of the cliff ecosystem. We recorded 231 vascular plant species across 39 locations spanning altitudes from 100 m to 1300 m and latitudes from 15° to 21° N, using the transect-quadrat method. A total of 480 quadrats measuring 1-m² were sampled across 80 transects on the cliff faces. Nine PFTs were identified in NWG cliffs with dominance of carnivores and therophytes. We examined the impact of environmental filters on PFT distribution and their interactions through bivariate and multivariate analyses. Significant variations in PFTs were observed across altitudinal and latitudinal gradients. The principal component analysis identified temperature and precipitation as primary influencers, outweighing altitude and latitude. Redundancy analysis indicated that stress-tolerant PFTs predominated in hotter, drier conditions, whereas stress-avoidant PFTs thrived in areas with higher precipitation, typically found at lower to mid altitudes. Our study underscores a stronger correlation between plant communities on cliff faces and altitude rather than latitude in the NWG.
