The Spanish network of drove roads, a series of traditional routes which have been maintained through the practice of transhumant grazing and livestock movements, plays a fundamental role in mitigating some of these negative impacts. This network, functioning as a form of green infrastructure, provides permanent semi-natural grasslands that serve as refuges for pollinators in particularly intensively managed agricultural landscapes. To explore the effect of the <em>Conquense</em> drove road –over 400 km long and one of the most frequently used transhumant drove roads in Castilla-La Mancha (central Spain)– on the wild bee community, we sampled a 240 km section that extends across three distinct ecoregions (Campo de Calatrava, Llanura Manchega and Mancha Alta), which differ biogeographically in terms of geology and geomorphology, likely resulting in differences in bee communities. We collected wild bee specimens using pan traps across three land use types present within each ecoregion: drove road grasslands, patches of semi-natural vegetation and intensive crop fields. Wild bee community composition showed significant differences between the three ecoregions. Drove roads showed a significant positive effect on species richness and Shannon’s diversity when the availability of semi-natural habitat was low. Functional richness of wild bees was significantly higher in drove road grasslands compared to the other two land use types (semi-natural vegetation and crops). Moreover, the interaction between semi-natural cover and drove roads revealed a significant positive effect of drove roads on both functional richness and dispersion, particularly under conditions of low semi-natural habitat cover. Our study highlights that drove road grasslands can offer suitable habitat resources that support bee taxonomic and functional diversity, particularly in landscapes heavily transformed by intensive agriculture and with reduced availability of semi-natural areas. The EU Pollinators Initiative emphasizes the need of restoring natural habitats in agricultural landscapes and creating a network of ecological corridors for pollinators. In this context, the preservation of the Spanish network of drove roads is highly relevant. Drove road grasslands, when maintained through traditional transhumant grazing, can provide feeding and nesting resources to wild bees and other pollinators, especially within a highly intensified agricultural matrix.</div></div>","PeriodicalId":7512,"journal":{"name":"Agriculture, Ecosystems & Environment","volume":"393 ","pages":"Article 109777"},"PeriodicalIF":6.0,"publicationDate":"2025-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144184729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The moderately diverse regional mixture resulted in the highest richness; including insect-pollinated species, while the most diverse mixture and high-density seeding showed lowest colonisation by unsown species. Among the commercially available (and thus cheaper) mixtures, the one with lowest diversity performed worst in terms of sown species establishment, species richness and the proportion of unsown plants.

The results showed that dicyandiamide inhibited nitrification only at temperatures lower than about 20°C and under relatively dry conditions but not at higher temperatures or under high rainfall. In contrast, 3,4-dimethylpyrazole phosphate and 3,4-dimethylpyrazole succinic acid effectively inhibited nitrification for all crop seasons. 3,4-dimethylpyrazole phosphate and 3,4-dimethylpyrazole succinic acid were effective in reducing nitrous oxide emissions (<em>P</em> &lt; 0.05), but not dicyandiamide. Nitrification inhibitor application did not affect methane uptake by soil. Even though nitrification inhibitor applications did not increase the cabbage yield or nitrogen use efficiency, they could reduce the fertilizer application time (i.e., two fertilizer application times for urea vs only one basal fertilizer application time for nitrification inhibitor treatments). Additionally, 3,4-dimethylpyrazole phosphate and 3,4-dimethylpyrazole succinic acid maintained the yield even at a low nitrification inhibitor rate (0.5 % of applied nitrogen). Moreover, the former maintained yield at even a low nitrogen rate (175 kg N ha⁻¹, 70 % of the local standard application rate of 250 kg N ha⁻¹).

In this study, we investigated whether extreme climatic events associated with global warming are altering the composition of insect-pollinated plant species and whether this is leading to exacerbated changes resulting from the disruption of plant-pollinator interactions. We conducted an experiment to artificially induce extreme climate conditions, which allowed us to analyse their impact on the flower colour composition of vegetation communities. The experiment was carried out in a wet grassland. We measured flowering phenology and flower colour visual signals of bees and flies (hue, saturation, and brightness) under the influence of simulated changes in environmental conditions. The results showed that additional irrigation and passive warming accelerated the onset of flowering and reduced the number of flowering insect-pollinated species over the growing season. Additional irrigation, increased temperature, and their interaction increased flower saturation of bee and fly visual spaces, and decreased saturation in butterfly visual space colour within the analysed plots. We also found that changes in water availability can lead to selective pressures that favour different flower colour traits, potentially affecting the overall dynamics of pollinator interactions. Additional irrigation reduced the proportion of bee-green and fly-yellow plant species. Warming without additional irrigation increased the proportion of bee-green species, but decreased the proportion of bee-UV-green and fly-UV cover plants. Moreover, the analysed factors and their interaction drive changes in the composition of plant communities that shape hue perception patterns in butterflies. These results highlight the complexity of ecosystem responses to climate-related factors, where multiple interacting variables can lead to unexpected changes in floral traits, such as changes in flower colour saturation of different pollinator groups or shifts in dominant hues, ultimately impacting pollinator behaviour and potentially overall biodiversity.</div></div>","PeriodicalId":7512,"journal":{"name":"Agriculture, Ecosystems & Environment","volume":"392 ","pages":"Article 109772"},"PeriodicalIF":6.0,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144154619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary objective is to elucidate the contributions of degradation levels, SOC component and the extent of pika disturbed areas to the impact of pika disturbance on SOC storage. The results indicate that, (i) pika disturbance increases SOC content by 10.1–23.8 % and 13.3–28.6 % in lightly (LDM) and moderately (MDM) degraded grasslands at 10–45 cm, while decreases it by 10.1–18.3 % in severely degraded grassland (SDM) at 0–20 cm. Structural equation models (SEM) analysis suggests that, the total effect of grassland degradation levels is more than twice of pika density on SOC content. (ii) Pika disturbance induces greater changes in particulate organic carbon (POC) content compared to mineral-associated organic carbon (MAOC), resulting in a more pronounced increase in its total effects on SOC content, particularly in MDM. (iii) The impacts of pika disturbance on SOC content and its components differ between pika burrow holes and tunnels, with the decreases predominantly observed in burrow holes rather than tunnels. These findings suggest that the effects of pika disturbance on SOC storage are more strongly associated with grassland degradation levels than with pika density.

Socio-demographic and farm management data were collected from 242 farms on three sites in southern-central and northern Benin. Principal component analysis and a hierarchical clustering were used to construct a farm typology. Soil management practices were analysed in the light of this typology. Composite soil samples 20 cm deep were then taken from 40 plots representing the farm/soil types identified, to assess variability in soil fertility as influenced by farm types and management practices. Four farm types emerged, differing in resource endowments and soil management practices. Practices such as manure application (92 %) and rotational herd corralling (42 %) were adopted more often by livestock owners. Farms without livestock implemented practices such as crop rotation (90 %) and intercropping (41 %). Soil fertility status was low to very low in all farms sampled across the three sites (extractable phosphorus &lt;10 mg P/kg soil, soil organic matter &lt; 20 g kg⁻¹ soil). Although a link between farms’ soil management practices and soil fertility status was expected, no statistical differences were detected across farm types (p &gt; 0.05). Cotton yields, as declared by farmers, were also not statistically associated with soil fertility levels. The generalized poor fertility status of soils that receive annual fertilizer inputs suggests that this practice is not enough to maintain long-term soil productivity in the climatic and soil conditions of Benin cotton zones studied here. This was also the case in fields that received combinations of mineral fertiliser and animal manure, which is probably not used in sufficient quantity and quality.
