However, standardised monitoring of biodiversity is time-consuming and cost-intensive. Citizen science (CS) initiatives therefore may provide valuable data and may complement data collected by professionals. Photo-apps equipped with automated taxonomic identification based on artificial intelligence play a central role in CS, at least for well distinguishable organisms such as the majority of butterfly species. In this study, we analysed butterfly (Papilionoidea) observations collected with three different photo-apps (i.e. <em>Blühendes Österreich, iNaturalist, observation.org</em>). We compared these data with observations from the <em>Global Biodiversity Information Facility</em> (GBIF). For this purpose, we classified each butterfly species according to its detectability and attractiveness, as well as its ecology and behaviour. Our results show that the observations obtained from the three photo-apps mainly cover mobile, conspicuous and easy-to-identify species, while the rare and sedentary specialist species and species that are difficult to distinguish from other taxa are underrepresented. Furthermore, the observations collected differ significantly between the three apps, and <em>Blühendes Österreich</em> particularly lacks inconspicuous butterfly species. However, a detailed regional analysis of user performance revealed that the differences among the three apps largely stem from Austrian-wide difference in app usage and less to user specific biases in recording. Within single habitats, amateurs and semi-professional users performed similarly in recording. In consequence, a combination of the data from the various apps might provide a largely realistic picture. However, most rare and ecologically demanding species seem to be covered inadequately. Thus, the recording of such species must be continued by experts to obtain a comprehensive picture of regional biodiversity.</div></div>","PeriodicalId":8708,"journal":{"name":"Basic and Applied Ecology","volume":"87 ","pages":"Pages 46-54"},"PeriodicalIF":3.0,"publicationDate":"2025-06-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144320826","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}

Already in the first year after sowing, vineyard inter-rows sown with the new seed mixture showed comparable vegetation cover as conventionally greened vineyard inter-rows, thus ensuring suitability for vineyard work. In addition, we found significantly higher forb cover and species number within the biodiversity vineyards, while the control vineyards showed a significantly higher grass cover. We observed significantly higher PFI values in the biodiversity vineyards as compared to the control vineyards. The introduced plant species did not only increase plant diversity, but could also be an important nectar and pollen source for pollinating insects.

We hypothesised that bumblebees avoid flowers exposed to noise more than flowers in non-noisy environments, leading to less efficient pollination and lower fruit quality. Three treatments were applied to randomly chosen plants and flowers in polytunnels in Hungary: noisy (with played traffic noise and allowing bumblebees to access the flowers); and two non-noisy, one allowing bumblebees and one excluding them. The flowers were bagged with nets before anthesis to prevent bumblebee visits, opened/unbagged exclusively during treatment, and re-bagged for three more days post-treatment. We recorded the market value of the fruits and the number of seeds they produced. We found no significant differences in the market value of fruits among treatments, but the number of seeds was significantly lower in the noisy treatment, suggesting that anthropogenic noise has substantial effects on bumblebee-mediated pollination. Although these effects may be mitigated by habituation, loud external noise of various machines (e.g. irrigation systems) within polytunnels is still likely to contribute to the everyday noise exposure of bumblebees and could thus potentially lead to hidden economic losses in production. Therefore, further research is needed to understand the behavioural effects of both direct and indirect noise pollution on bumblebees.</div></div>","PeriodicalId":8708,"journal":{"name":"Basic and Applied Ecology","volume":"87 ","pages":"Pages 11-19"},"PeriodicalIF":3.0,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144223583","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}

Second, to explore hypotheses for the mechanisms of spatial variation in masting in <em>Fagus</em> and disentangle the effects of geographical and climate variables, we fitted coarse qualitative data (seeding rank) for a 20-year period for 102 populations of <em>Fagus crenata</em> across 550 km in northern Japan to the process model above, encompassing variable average climate conditions and latitudinal genetic divergence. We found good agreement between observed and predicted numbers of flowers and seeds at the test site. A simulation demonstrated that the process model reproduced the observed masting pattern well. Fitting data for the 102 sites allowed us to develop new hypotheses. The indicator of the effect of higher summer temperatures as a weather cue for masting decreased with latitude, possibly reflecting latitude-associated genetic divergence. The indicator of the evasion of insect predation was positively correlated with winter precipitation, possibly due to poor survival of the primary seed predator of <em>F. crenata</em> in heavy-snowfall areas. These hypotheses related to spatial variation in masting patterns should be tested in future studies.

Likewise, the mean ecological indicator values for temperature increased throughout. While the mean ecological indicator values of nutrient, soil moisture and reaction remained constant for the set of all plots, at lower elevations there was a trend towards a decreased nutrient value whereas soil moisture decreased at higher elevations. Overall, more species showed positive rather than negative trends over time. Especially at lower elevations, short-lived, ruderal species and C<sub>4</sub> grasses are on the increase. We suggest that these trends are linked to the increased harvesting frequency and the recent trend towards longer dry spells in Swiss summer.

To combat these declines, it is essential to understand demographic mechanisms underlying the negative population trends. For this purpose, we employ a novel modelling approach on a long-term multispecies dataset collected by citizen scientists throughout Czechia. Using this approach, we calculated recruitment, adult survival and population growth rates for 13 farmland bird species on annual basis from 2004 to 2021, and related these demographic rates to species population trends estimated over the same period, as well as to their habitat preferences. We observed a negative relationship between recruitment and adult survival within most species. This relationship becomes increasingly more negative in species breeding in more open habitats. These species also showed steeper population declines and less positive correlation between adult survival and population growth rate than species breeding more woody habitats. These results indicate that the open-habitat farmland birds face strong population regulation. Under such regulation, higher adult survival in some years, that may occur due to, for instance, suitable weather conditions, does not leave much capacity for new recruits, and thus is immediately compensated by low recruitment. We suggest that these demographic processes are underpinned by decreasing carrying capacity of the open habitats which may occur due to shrub encroachment or afforestation of agricultural land that are widespread in Europe. At the same time, species preferring woody habitats enjoy increasing habitat availability in farmland which may lead to population increases over the long-term. Our results indicate that conservation actions are needed to improve the carrying capacity of the open habitats, especially during the breeding season.

The dissimilarity in bacterial communities between paired samples was positively related with the differences in longitude and environmental factors (mean annual precipitation and soil pH in particular) for the two soil origins.
