Here, we analysed the effects of wild boar rooting in abandoned calcareous grasslands of the Hainich National Park, Germany, on two rare butterflies: marsh fritillary (<em>Euphydryas aurinia</em>) and Nickerl’s fritillary (<em>Melitaea aurelia</em>). We sampled different environmental parameters as well as butterfly frequency and abundance in wild boar rootings and undisturbed calcareous grassland vegetation. Our study demonstrated that wild boar play a vital role as soil disturbing ecosystem engineers for the persistence of the butterfly species. They created early seral stages rich in bare ground, hence a warm microclimate, and host plants. The two fritillary species used almost exclusively (<em>E. aurinia</em>) or even solely (<em>M. aurelia</em>) rooting patches for reproduction. Overall, occurrence and abundance of the butterfly species were best explained by a (i) high host plant abundance/biomass and (ii) warm microclimate. Based on our study, high densities of wild boar and additionally wild herbivorous ungulates, which slow down the expansion of woody plants by browsing, should generally be promoted in the calcareous grasslands of the national park. However, overall, they cannot halt shrub encroachment and thus the continuous loss of calcareous grasslands. Accordingly, we recommend active grassland management, e.g. exhaustive shrub removal followed by large-scale grazing by cattle and horses with low stocking rates.</div></div>","PeriodicalId":54264,"journal":{"name":"Global Ecology and Conservation","volume":"58 ","pages":"Article e03451"},"PeriodicalIF":3.5,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143147726","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}

The cyclical rhythm of water level changes determines the dynamic variations in the wetland landscape pattern of Poyang Lake, directly impacting the habitat and survival of wintering migratory birds, particularly wading birds, which are most sensitive to these changes. This study employs an Artificial Neural Network (ANN) algorithm to interpret wetland landscapes using the Gao-Fen Satellite Images across 14 different water levels. Methods such as Pearson correlation and linear fitting are used to analyze the effects of water level changes on the habitat of wintering wading birds, aiming to explore scientifically based optimum water level. The ultimate goal is to provide a scientific basis for determining the optimum water level regulation scheme for the proposed Poyang Lake Hydraulic Project. The results indicate that the area and shape of Poyang Lake's wetlands are highly plastic, with landscape heterogeneity decreasing and homogeneity increasing as water levels rise. The habitat area for wintering wading birds shows an inverted \"V\" shape variation with rising water levels, reaching a maximum of 1796.02 km² at a water level of 9.86 m, which accounts for about 48.40 % of the study area. The water level changes in Poyang Lake significantly impact the landscape pattern of the wading bird habitats (<em>p</em> &lt; 0.01). When 6.83 ≤WL→WL<em>x</em> m, wading bird habitats become increasingly fragmented, with habitat patch type diversity, evenness, and connectivity gradually improving. When WL<em>x</em>→WL≤ 15.46 m, the degree of fragmentation moderates, but the diversity, evenness, and connectivity of habitat patches gradually decrease. At water levels between 8.15 and 13.56 m, the habitat structure for wintering wading birds is complex, with high diversity, large habitat area, and good landscape connectivity, providing favorable food acquisition resources and adequate space for wintering wading birds. Based on the need for wintering waterbird conservation, the proposed optimal optimum water level regulation threshold for the Poyang Lake Hydraulic Project is suggested to be between 8.15 and 13.56 m.</div></div>","PeriodicalId":54264,"journal":{"name":"Global Ecology and Conservation","volume":"58 ","pages":"Article e03453"},"PeriodicalIF":3.5,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143147350","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}

However, lack of assessment of specific habitat changes caused by anthropogenic disturbance limits effective conservation management for marine species in estuarine habitats. Here, using the Chinese white dolphin (<em>Sousa chinensis</em>) in Xiamen Bay as a case study, we used species distribution models to simulate Chinese white dolphin habitats during the late 1990s, early 2010s, late 2010s and early 2020 s, using historical occurrences and environmental variables interpreted from Landsat images. Over this time period, the Chinese white dolphin population experienced substantial habitat fragmentation and niche shifting. Driven by anthropogenic disturbance, the Chinese white dolphin population moved away from river mouths during 1994–2019, resulting a temporary increase in 50 % kernel density estimation (KDE) and habitat in early 2010s, followed by a decrease in the late 2010s. However, the population’s hypervolume decreased gradually to 32.1 % in early 2010s and 7.7 % in the late 2010s, reflecting loss of estuarine resources of the Chinese white dolphins. By early 2020 s, the 50 % KDE and habitat further decreased while the hypervolume increased to 58.2 %, probably due to availability of new estuarine habitats when the population colonized the northeast and southwest of this area. In conclusion, Xiamen Bay has gradually transformed from a refuge into an ecological trap for the Chinese white dolphin. In order to reverse this negative population trend, protected areas should be adjusted to include habitats in the Jiulong River Estuary, Weitou Bay, and the waters between them. Immediate interventions should be conducted to reduce anthropogenic disturbance and improve habitat quality. Ecosystem-based management and long-term monitoring are strongly recommended to avoid potential extinction of many other estuarine species caused by coastal urbanization.</div></div>","PeriodicalId":54264,"journal":{"name":"Global Ecology and Conservation","volume":"58 ","pages":"Article e03448"},"PeriodicalIF":3.5,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143147297","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}

In the Negev desert of Israel, habitat loss and environmental disturbances have driven the population of MacQueen's Bustard, AKA Asian Houbara (<em>Chlamydotis macqueenii)</em>, one of Israel's flagship species, to the verge of extinction. Although this remnant population is considered sedentary, observations suggest that a large part of the population performs short-distance migration between the breeding and post-breeding grounds in the northwestern Negev using short flights and on-foot movements. We utilized GPS data from nineteen males equipped with GSM-GPS devices and Maximum Entropy species distribution models to characterize, for the first time<em>,</em> the 1) male home ranges during the courtship period and 2) critical corridors utilized when performing short flights and on-foot movements between the breeding and post-breeding grounds in the northwestern Negev. The most influential predictors of male courtship areas were elevation, January precipitation, and soil type, displaying the range of environmental conditions best suitable for establishing a male courtship home range along the steep climate and topographic gradients characterizing the Negev desert of Israel. Zooming into the northwestern Negev, where most of the population occurs, showed that the most influential predictor variable was soil type. A compositional analysis indicated two groups of courting males in the northwestern Negev and a third group in the Negev Highlands. The first group, comprising ten males occupying a land unit dominated by loess-derived soils, significantly preferred loessial serozem soils. The second group, including six males occupying a land unit dominated by sand-derived soils, significantly preferred sand dunes and sandy regosols. The third group, comprising three Negev Highlands males, showed a preference for regosol-reg and desert alluvium soils. The home range sizes of courting males were positively correlated with their body masses. The total distance each of the migrating males covered while wandering until arriving at the post-breeding ground was, on average, 171.39 km, and it comprised primarily on-foot movements (68 %) rather than short flights (32 %). Areas of relatively uniform elevation and gentle/simple topography characterized the on-foot movement corridors utilized during the short-distance migration between the breeding and post-breeding grounds in the northwestern Negev, possibly reflecting a preference for vast, unobstructed areas that enhance the field of vision while on the ground. A common finding across both activity seasons was a distinct avoidance of agricultural lands and favoring open natural habitats. Some courtship sites and on-foot movement corridors are primarily found outside nature reserves.

The results reveal that in conditions of light grazing, microbial metabolic processes are co-limited by C and P, whereas in ungrazed plots and those subjected to different grazing treatments, limitations are primarily due to C and N. Key determinants of microbial carbon limitation include nutrient availability and the ratio of microbial biomass, while limitations pertaining to N, and P are primarily influenced by microbial biomass levels and their respective ratios. Notably, microbial carbon use efficiency peaked under light grazing conditions. Therefore, sustained light grazing can modify the limitations affecting soil microbial metabolism and enhance microbial carbon use efficiency.
