Our results suggested that low N enrichment strengthened the positive relationships between species richness and ecosystem function. Species richness increased ecosystem function mainly by increasing phylogenetic diversity and functional dispersion of aboveground and belowground traits (niche complementarity effect). N enrichment directly increased ecosystem function, while it decreased ecosystem function through its negative effects on community weighted means of aboveground and belowground traits (mass ratio effect). Additionally, aboveground and belowground traits affected ecosystem function through different ways, and belowground traits played more direct roles than aboveground traits. Our findings emphasize that increasing the phylogenetic diversity (PD) and functional dispersion (FD) of traits could consistently improve ecosystem performance, irrespective of N enrichment.

This three-year experiment aimed to: i) select the plant species that survived the agronomic disturbance practices implemented and ii) verify which crop management approach favoured their sustainability. Six experimental strips along the longest edges of the adjacent wheat crop were sown during the fall of 2019. The annual wildflower species that showed the best performances in emergence dynamics and seedling growth were some wildflowers derived from segetal weeds that are presently rare in conventional agroecosystems. The species <em>Centaurea cyanus</em>, <em>Agrostemma githago, Glebionis coronaria</em> among others attained the phenological stage of flowering most consistently, and also had the lowest mortality rates in the plant community studied. Despite preparing a stale seedbed, weeds were the most significant obstacle to the sustainability of the strips over time. Soil harrowing at the end of the summer lifecycle led to better plant survival performances (10.9 %) compared to senescent plant shredding (4.8 %). Harrowing also resulted in a greater wildflower survival the following year, as well as a higher number of pollinator visits. Honeybee visits were decreased by wildflower strip thinning over time, probably due to their typical constancy in the daily foraging choice for the same abundant species. A similar reduction was observed by the Lepidoptera. In contrast, generalist pollinators (i.e. Syrphidae, Bombyliidae, solitary bees and Coleoptera) were the least demanding pollinators in terms of the plant biodiversity of the sustainable wildflower strip. Harrowing led to a greater biodiversity of both wildflowers and pollinators (Shannon index, H′), and a lower weed dominance (Simpson index, D), compared to shredding. In summary, some segetal wildflowers could be incorporated into sustainable wildflower strips as they are self-seeding.</div></div>","PeriodicalId":11490,"journal":{"name":"Ecological Engineering","volume":"212 ","pages":"Article 107486"},"PeriodicalIF":3.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143165522","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}

Environmentally, socially, and economically sustainable technologies should be investigated to address the issue, and Soil and Water Bioengineering (SWBE) represents a suitable solution. This study describes the first-ever application of SWBE in the country, realized within the World Bank's Burundi Landscape Restoration and Resilience Project (PRRPB). An experimental installation of SWBE was implemented in the hilly Isare municipality (Colline) using the training sites method. The overall feasibility of the installation was evaluated through an analysis of the growth of the plants used – a botanic analysis - a transferability analysis and a cost analysis. The botanic monitoring highlighted that a relatively good survival rate was achieved at the site of the experimentation. The transferability analysis results showed minor constraints (mainly know-how on SWBE techniques and the availability of materials, qualified labor, and equipment and mechanical instruments) but no major ones. On the other hand, the presence of high botanical knowledge, jointly with the local biodiversity, and the economic advantages of SWBE, represent decisive factors that can guarantee successful transferability. In terms of costs of a sample SWBE technology (double crib wall), our results show a reduction of 42 % and 72 % in terms of Purchasing Power Parity $ (PPP$) for mechanical and manual excavation respectively, with reference to the cost of the same work in an EU country (Italy). In addition to this, such technology is much cheaper than a gabion wall (−25 % if the crib wall is installed with mechanical excavation; −105 % if with manual excavation) and a concrete wall (−326 % with mechanical excavation; −598 % with manual excavation). The results of this paper show that SWBE is potentially transferable to Burundi, allowing the solution of some of the land degradation problems in the country, specifically targeting small- to medium-sized landslides, and also to countries with similar landscapes and social settings. More experimental installations and more research on the barriers should be realized. The proposed approach can be replicated in any central African country endangered by erosion and landslides.</div></div>","PeriodicalId":11490,"journal":{"name":"Ecological Engineering","volume":"212 ","pages":"Article 107510"},"PeriodicalIF":3.9,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143165787","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}

One of the key challenges is optimizing wetland design to ensure consistent performance throughout the year. To date, the impact of hydraulic performance on pollutant purification remains debated, and studies examining the correlation between their seasonal fluctuations are limited. This study conducted orthogonal experiments involving three categories of wetland parameters: geometric, hydraulic, and water quality parameters, to analyze the seasonal variability of the two wetland performance metrics. The results indicated that hydraulic performance presented high consistency across seasons and was more influenced by geometric and hydraulic parameters. Generally, FWS CWs with lower water depths and larger aspect ratios exhibited superior hydraulic performance. The purification effect for nitrogen showed obvious seasonal fluctuations, whereas phosphorus purification remained relatively stable.

Both TN and TP CREs exhibited strong negative correlations with flow rate and influent nitrogen concentration, while load removal rates demonstrated strong negative correlations with water depth.
