Consequently, they are considered important indicators of ecological changes in grasslands. To assess and maintain ecosystem functionality, it is essential to understand the ecological niches of Orthopteran insects. This includes analyzing niche breadth, interspecific relationships, biological requirements, tolerances, and niche overlap among sympatric species. However, how these ecological dynamics respond to grazing in desert steppe ecosystems remains largely unexplored. Through a grazing experiment initiated in 2004 on desert steppes, with sampling conducted in 2021 and 2022, this study analyzed the response of grasshopper niche width, niche overlap, and interspecific connectivity under different grazing intensities, providing insights into the effects of long-term grazing on the dominant insect group. Results showed that the increase in grazing intensity significantly expanded the niche widths of <em>Myrmeleotettix palpalis</em> and <em>Oedaleus decorus asiaticus</em>, while significantly reducing the niche width of <em>Calliptamus abbreviates.</em> The overlap of grasshopper niches significantly decreased with increasing grazing intensities, suggesting a strategy to mitigate competition amidst reduced plant resources. Concurrently, interspecific associations shifted from non-significant to significantly positive, indicating a potential for ecological facilitation and increased species interdependence under higher grazing pressures. Increases in grazing intensities resulted in grasshoppers adapting their strategies for plant resource utilization in response to environmental changes, which helped to mitigate direct interspecific competition and may have contributed to the development of a more stable ecosystem state.</div></div>","PeriodicalId":54264,"journal":{"name":"Global Ecology and Conservation","volume":"59 ","pages":"Article e03528"},"PeriodicalIF":3.5,"publicationDate":"2025-03-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143621529","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 influence of these factors, along with gender and season (winter and summer), on stress and sexual hormones was determined. The results showed that season significantly affected cortisol, testosterone, and progesterone levels, with red deer experiencing greater stress and higher testosterone and progesterone levels in summer compared to winter. Total percentage of vegetation and elevation did not have significant effects on these hormones. There was no significant correlation between cortisol and testosterone or progesterone in red deer.

In this study, we genotyped 168 samples including 74 males and 94 females <em>R. losea</em>, live-captured from five neighboring islands during breeding seasons.

Our analysis revealed a population density increase from 18 to 24 cats /100 km², from 2019 to 2023, and indicated a positive population growth rate (λ = 1.16). However, spatial survival probabilities were moderate 0.50 (95 % CI 0.33 – 0.67), likely due to isolation and human-caused mortality as suggested by interviews of local people. Despite conservation challenges, the population may be sustaining itself through high rates of recruitment (76 %) and turnover (80 %). Fishing cats exhibited a preference for natural areas with less disturbance within this anthropogenic landscape. This suggests that some relatively urbanized lands could potentially serve as refuge habitats for these felids. The preservation of existing habitats, especially within and near the national park is crucial for their survival, whereas increased law enforcement is unlikely to be an effective approach to achieve sustainable conflict mitigation.

By comparing the distribution of pangolin burrows with historical records, we evaluated changes in their range within the park. We analyzed relationship between environmental factors and presence of pangolin’s burrow to identify the habitat preference. From June 2018 to November 2019, we recorded 707 pangolin burrows across more than 90 % of the 94 surveyed grid cells. The consistent presence of pangolins in historically active areas suggests that their distribution within the park has remained largely stable. Habitat selection modeling indicated a preference of pangolin for Formosa acacia forests, areas with higher solar radiation, and lower elevations. While proximity to roads and human settlements did not significantly influence habitat selection, pangolins tended to avoid areas near hot springs which was associated with human disturbance such as recreational activity. Although we found that termite abundance was not significant different between sites with and without pangolin burrows, the sample size was limited. This research provides updated information of distribution of Chinese pangolins in the national park that can serve as baseline data for future population monitoring.

Our results revealed that the DBH of <em>D. alata</em> ranged from 5 to 75 centimeters, and there was no discernible spatial pattern. Environmental suitability could not predict the spatial variation in DBH. Nonetheless, plants with larger DBH were found in regions classified as pasture in terms of land use. Factors such as reduced competition soil management and age of plants (old plants) may help explain why DBH was greater in pasture areas. It is worth noting that although pasture areas can serve as a refuge for some trees, proper management is essential to promote individuals’ recruitment, ensuring population regeneration and the maintenance of diversity in long time.

Productivity and disturbance influence species richness and structure, enhancing our understanding of vegetation dynamics and species coexistence over time. Numerous theories, such as the Intermediate Stress Hypothesis, Intermediate Disturbance Hypothesis, and Dynamic Equilibrium Model, have been proposed to explain these mechanisms. However, our understanding of how productivity and disturbance affect the spatio-temporal dynamics of Isoberlinia-dominated woodlands remains limited. We analyzed floristic data from sixteen sites with 64 permanent plots (400 m² each) along a south-north precipitation gradient (1112–991 mm per year) over 15 years (2006–2020). We calculated species richness and density for sapling and adult trees, and estimated two main variables: potential productivity using water deficit as a proxy, and disturbance intensity using logging rate. A linear mixed effects model, with plots nested within sites as random variables, was developed to test the effect of potential productivity and level of disturbance on species richness and density, for sapling and adult trees. Our results showed that species richness (SR) and density, for saplings and adult trees decreased over time, regardless of the disturbance and potential productivity gradients. Compared to higher levels of disturbance, low and medium levels of disturbance significantly increase the species richness of saplings and adult trees. In addition, the density of adult trees and saplings decreased over time, but increased with the level of disturbance from high to low. These results suggest that increased disturbance reduces the density of woodland species in favor of invasive species, typically savanna species. Overall, our results are consistent with the Dynamic Equilibrium Model, highlighting the complex interactions between disturbance regimes, productivity gradients, and their effects on species richness within ecosystems. Efficient forest management in Isoberlinia-dominated would avoid the high levels of logging that promote the establishment of invasive species and would maintain the biodiversity of this ecosystem in the long term.</div></div>","PeriodicalId":54264,"journal":{"name":"Global Ecology and Conservation","volume":"59 ","pages":"Article e03512"},"PeriodicalIF":3.5,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143549643","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}
