Semi-natural habitats within agricultural landscapes such as hedges, grasslands or herbaceous field margins, provide resources and refuge to beneficial arthropods. In vineyards, extensively used inter-row vegetation may be functionally equivalent to such semi-natural habitats, and sowing of plant species rich in floral resources may improve habitat functions. In this study, three types of vineyard inter-row vegetation treatments were compared in 15 vineyards of South-eastern France: (1) sowing a high-diversity seed mixture (HD) with a high number of nectariferous plant species, (2) spontaneous vegetation, and (3) tilled inter-rows. We monitored the inter-row vegetation including problematic weeds, the abundance of beneficial arthropods, and the predation of sentinel prey. The invasive weedy grass species <em>Cynodon dactylon</em> showed a lower cover in HD inter-rows than in spontaneous vegetation, whereas no differences were found for the invasive herb <em>Erigeron sumatrensis.</em> Both weed species were still best controlled in tilled inter-rows. Beneficial arthropods were less abundant in tilled than in spontaneously vegetated and sown inter-rows. Day predation was higher in HD inter-rows than in spontaneous vegetation although no significant differences were found for observed predators. Over all treatments, plant species richness, flower and grass cover had a positive influence on several beneficial arthropod groups. Our results highlight the positive effects of species-rich inter-row vegetation on weed control, beneficial arthropod abundance and predation but also showed that further research is needed to improve the efficiency beyond services already provided by spontaneous vegetation.</div></div>","PeriodicalId":8708,"journal":{"name":"Basic and Applied Ecology","volume":"81 ","pages":"Pages 17-24"},"PeriodicalIF":3.0,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142535250","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}

While many studies have emphasized the importance of natural/semi-natural elements and their diversity within or surrounding farmlands, it remains unclear how crop diversity impacts birds. There is also a significant gap in our knowledge regarding the effects of temporal changes in crop composition on bird diversity. Using small farmlands in a sub-tropical city of China, we examined how spatial and temporal variation of crops and other local farmland features was linked to species diversity of birds and their traits. In small peri‑urban agricultural areas of Guangzhou, we collected bird and crop/non-crop data approximately bimonthly from December 2021 to October 2022. Overall crop diversity and seasonal crop changes were indexed by alpha diversity (Shannon-Wiener index) and beta diversity, respectively. Both alpha and beta crop diversities were positively associated with Shannon-Wiener diversity of birds. Alpha crop diversity also tended to have a positive impact on species richness. Percent cover of woody vegetation showed a positive effect on all three bird diversity indices, i.e., species richness, Shannon-Wiener diversity, and evenness. Percent cover of rice affected species richness positively and evenness negatively, whereas the effects of percent cover of corn were the opposite. In a fourth-corner analysis, the abundance of plant/seed-eating birds was negatively associated with alpha crop diversity, whereas the abundance of ground-foraging birds was positively associated with beta crop diversity. These patterns indicate that seasonally dynamic crop changes as well as local crop diversity can influence bird diversity and traits in small farmlands. They also suggest that natural/semi-natural woody vegetation, such as trees and shrubs, play a critical role in enhancing species diversity of birds in farmlands dominated by herbaceous edible crops.</div></div>","PeriodicalId":8708,"journal":{"name":"Basic and Applied Ecology","volume":"80 ","pages":"Pages 138-145"},"PeriodicalIF":3.0,"publicationDate":"2024-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142534494","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}

Mitigating the resulting arthropod decline is a great challenge. Dwarf shrubs in open areas might buffer microclimatic extremities by reducing the solar radiation reaching the ground and weakening air circulation near the soil surface. Forest steppes are mosaics of forests and grasslands covering a vast area in Eurasia. This heterogeneous ecosystem offers the opportunity to study the effect of small habitat features, i.e. dwarf shrubs, in dry grasslands and compare the fauna of rosemary-leaved willow (<em>Salix rosmarinifolia</em>) shrubs with forest patch interiors, open grasslands and their edges. We hypothesized that the dwarf shrub microhabitat has a wetter and cooler microclimate than open grassland and a different spider community composition than other forest-steppe microhabitats. We recorded microclimatic parameters with data loggers, measured soil moisture with TDR and collected ground-dwelling spiders with pitfall traps. We detected the highest soil moisture (6.26 ± 1.21%, mean ± 95% confidence interval) and air humidity (80.19 ± 3.19%) in forests and the lowest in grasslands (4.36 ± 0.65%; 66.59 ± 2.53%, respectively). The warmest microhabitats were grasslands (23.23 ± 0.51°C), whereas the coolest microhabitats were forests (18.92 ± 0.41°C). The distinct microclimate of dwarf shrubs was cooler (21.46 ± 0.41°C) and moister (5.43 ± 0.53%) than the surrounding semi-desert like grassland. Furthermore, we found a different spider community composition and trait state composition of spiders in forests, edges, grasslands and dwarf shrub microhabitats. Forests (9.90 ± 0.95) and edges (11.44 ± 1.27) hosted a higher species richness than grasslands (7.08 ± 4.27) and dwarf shrubs (5.09 ± 1.33). We collected larger spiders on the edges than in dwarf shrub microhabitats. The dwarf shrubs hosted a different microclimate and spider community composition from the grassland. Climate change in the forest-steppe region is assumed to be driven by a combination of warming and drying. In the coming decades, drought frequency and severity are predicted to increase. Woody vegetation, even dwarf shrubs, creates a thermal and moisture heterogeneity that might aid arthropods in buffering macroclimatic warming through behavioural thermoregulation. Therefore, their presence on grasslands can benefit the conservation of specialised grassland arthropods.</div></div>","PeriodicalId":8708,"journal":{"name":"Basic and Applied Ecology","volume":"80 ","pages":"Pages 92-100"},"PeriodicalIF":3.0,"publicationDate":"2024-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1439179124000677/pdfft?md5=d34248993eec6b66fb76f20cae6350ac&pid=1-s2.0-S1439179124000677-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142310848","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}

Nutrient availability in the topsoil and leaching in 50 cm depth as well as litter decomposition and radial growth of mature European beech trees were analysed. It was hypothesized that (1) wetter winters lead to increased nutrient deposition as well as leaching, with an overall increase in net nutrient availability, (2) decomposition decreases in response to water addition containing also additional nutrients and (3) primary production during the subsequent growing season increases as presumably not all additionally available nutrients would be leached. We found an increase in topsoil nitrate and sulfate availability during winter in response to rain addition, likely as a consequence of collecting more atmospheric deposition, and surprisingly high leaching rates of the additionally available nutrients. During the subsequent early growing season, no difference in nutrient availability could be observed anymore. Enhanced nutrient availability in the topsoil and leaching do not seem to have a strong short-term influence on forest ecosystem processes in ecosystems which are close to their critical load of N deposition.

Soil depth, which is the predominant characteristic of karst regions, possibly affects community assembly from the regional species pool into local communities. However, the influence of karst soil depth on plant community assembly mechanisms remains unclear. We investigated the community functional traits of karst shrublands by calculating community-weighted mean (CWM) traits for leaf dry matter content (LDMC), specific leaf area (SLA), leaf carbon content (LCC), leaf nitrogen content (LNC), leaf phosphorus content (LPC), and leaf potassium content (LKC). To explore the assembly pattern of karst shrublands, we assessed the extent of trait divergence or convergence using trait-based null model analyses. Additionally, we examined how community functional traits and assembly patterns changed with varying local soil depths. Karst shrublands were found to exhibit CWM trait combinations characterized by high LDMC and LCC, as well as low SLA, LNC, LPC, and LKC to adapting to harsh environments. Furthermore, the CWM of LDMC, LCC, LCC/LNC ratio, and LCC/LPC ratio significantly decreased, while SLA and LNC in karst shrublands significantly increased along soil depth gradients. This indicates that, as soil conditions improved, the karst shrubland community shifted from a conservative survival strategy to a resource-acquisition strategy. Overall, the convergence pattern prevailed in the karst shrubland communities for most leaf traits. As the karst soil depth increased, the traits of the shrubland communities shifted from a convergence pattern toward a neutral assembly. These results demonstrate for the first time that species were primarily assembled into karst shrubland communities through environmental filtering, while the importance of environmental filtering in the assembly process gradually weakened with increasing soil depth. Our study underlines the necessity of increasing soil quantity to allow more species from the regional species pool to enter local shrublands, thereby promoting karst community succession.</p></div>","PeriodicalId":8708,"journal":{"name":"Basic and Applied Ecology","volume":"80 ","pages":"Pages 40-48"},"PeriodicalIF":3.0,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1439179124000665/pdfft?md5=109f36c780172e5597c4bba944a509cb&pid=1-s2.0-S1439179124000665-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142232309","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}
