However, the effect of land-use intensity on plant distribution at small spatial scales, as indicated by the slope of the species-area relationship, is rarely investigated. We tested whether the species-area relationship is directly affected by land-use intensity or indirectly via plant species richness. We studied the species-area relationship by measuring the rate of species richness increase between different plot sizes. We used nested quadrats of 0.2 by 0.2 m and 1 m by 1 m within each of 147 4 × 4 m plots of managed grasslands in three German regions in 2017 or 2018. With linear models, we found that the different components of land use (mowing, grazing and fertilization) had various direct effects on the species-area relationship. Mowing reduced the slope of the species-area relationship, indicating a more even distribution of plant species within plots at higher land-use intensity. Fertilisation did not significantly affect the slope of the species-area relationship, while grazing increased it. As a result of these different component effects, overall land-use intensity did not affect the species-area relationship directly. In addition, we used structural equation modelling to assess the direct and indirect effect of land-use intensity on the species-area relationship. We found that land-use intensity had only a negative indirect effect on the species-area relationship through a negative effect on species richness. An additional analysis with land-use components, mowing and grazing, confirmed the indirect negative effect of land-use on species-area relationship. Our results underline the importance of testing direct and indirect effects of land-use intensity. Furthermore, we show the importance of considering regional environmental differences before being able to generalize land-use effects on plant species heterogeneity.</div></div>","PeriodicalId":8708,"journal":{"name":"Basic and Applied Ecology","volume":"87 ","pages":"Pages 92-99"},"PeriodicalIF":3.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144633586","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}

Land-use intensification and its consequences can shape both abundance and functional traits in pollinators, which may reduce pollination, and thus threaten ecosystem functioning. This study investigates temporal stability of land-use and climatic effects on morphological traits and abundance of the bumblebee <em>Bombus lapidarius</em> and the syrphid fly <em>Episyrphus balteatus</em> in agricultural grasslands. As responses, we measured body size and asymmetry using wing centroid sizes of specimen sampled in the years 2008, 2012 and 2020 and assessed the relative abundance of the two species. By using a variety of environmental variables on local and landscape-scale, reflecting land-use intensity and floral resource availability for pollinators, we were interested in the individual effects of the stressors, but particularly whether the effects are stable across the three sampling years. The body size of bumblebees decreased with local land-use intensity and increased with local availability of floral resources. In contrast the body size of syrphid flies decreased with landscape-level land-use and strongly depended on temperature. Bumblebee abundance declined with local land-use intensity, while syrphid flies were more abundant on plots with higher local land-use. The effects of most land-use stressors on both pollinator morphology and abundance showed consistent patterns across the three sampling years, except for local land-use and climatic factors, which showed significant interactive effects with the sampling year on the morphology of both species. Our results indicate that land-use effects on pollinators are stable over time and demonstrate that pollinators may be under persistent pressure of land-use in agricultural areas.</div></div>","PeriodicalId":8708,"journal":{"name":"Basic and Applied Ecology","volume":"87 ","pages":"Pages 38-45"},"PeriodicalIF":3.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144297018","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}

Obligatory status reports enable a broad-scale analysis of conservation states to investigate if biodiversity is in the favourable conservation status demanded by the directive and which factors may be inhibiting. With focus on Germany, we evaluated the conservation states of habitat types and species groups as assessed in standard data forms and related it to drivers commonly reported for the sites, e.g., land-use practices, protected area size and time since designation. Our results are based on assessments from 23 % (1049) of Germany’s Natura 2000 sites protected under the Habitats Directive and show that only 6 % of habitats’ and 4 % of species’ assessments report a favourable conservation status. A review of the reported drivers showed that most negative influences on Natura 2000 sites were attributed to agricultural and forestry activities, as well as natural system modifications, while for both land-use types also practices with positive impact were listed. For habitats, conservation status was better in Natura 2000 sites that were established earlier than later. For both habitats and species, more favourable conservation states were overall related to larger area sizes and the absence of direct land use (agriculture, forestry). Our results highlight that a high proportion of protected areas alone does not suffice to infer successes for biodiversity conservation when land-use activities continue to affect target species or their habitats.

Artificial light along these potentially leads to interruptions of commuting routes, or changes in flight behaviour of trawling bats, but impact of light may vary with light spectrum and intensity. Here, we tested whether pond bats change their flight speed and straightness in response to four light spectra at two light intensities by placing an experimental lamp post at bridges over waterways that are used by pond bats as commuting routes. We used a microphone array to precisely reconstruct the flight path of each passing bat and calculate flight parameters. Flight speed of commuting pond bats was unaffected by the presence of light, regardless of the light spectrum. Pond bats only fly straighter when exposed to white light (3000 K). The short presence of a lamp post with realistic light intensity on a bridge may therefore not act as a barrier. However, other direct effects cannot be excluded and the long-term presence of a similar light installation may still have impact.</div></div>","PeriodicalId":8708,"journal":{"name":"Basic and Applied Ecology","volume":"87 ","pages":"Pages 20-28"},"PeriodicalIF":3.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144243328","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}
