This investigation centered on delineating the variances in bioturbation impacts by plateau pikas on soil characteristics in alpine meadows under distinct population densities. Outcomes indicated notable discrepancies in SOC, TC, and TN levels between surface soil depth (0–10 cm) and deeper depth (10–20 cm) under different Active Burrow Density (ABD). Across different depths, SOC, TC, and TN concentrations exhibited an initial rise followed by a decline with escalating Active Burrow Density (ABD), reaching peaks within the range of 240–330 burrows per hectare. Additionally, SOC and TN levels displayed synchronized fluctuations across different depths, while TC levels did not exhibit such synchronicity; TC content in deeper depth lagged behind that in surface depth. Moreover, surface soil stoichiometry (C:N ratio) diminished with heightened ABD, whereas deeper depth exhibited an opposing trend. These findings underscore how plateau pika bioturbation reshape nutrient distribution patterns and soil stoichiometry, thereby influencing carbon turnover processes and cycling rates.

Significant distance dependence was observed in all landscapes except one. All primary forest landscapes deviated significantly from neutral model predictions; in contrast, only one of the disturbed landscapes deviated significantly. Deviation from neutrality in primary forest suggests potentially important contributions of niche specialisation and/or competitive exclusion in structuring butterfly communities. Disturbances like logging or fires, which open up the forest, seem to push these communities toward neutrality with greater species richness and evenness than proximate primary forest. Multiple disturbance events, however, appear to lead to a loss of species while maintaining relatively high evenness and communities consistent with neutral model predictions. Furthermore, the butterfly communities of once- and twice-burnt landscapes appeared to consist of species with greater tolerances to disturbance or able to rebound following disturbance in addition to species, which entered from surrounding severely degraded habitat. Interestingly, a frequently-burnt landscape, now largely devoid of forest, aligned with neutral model predictions. This landscape contained a low-richness, highly impoverished fauna consisting of widespread generalists, but with relatively high evenness. We suggest that differentially disturbed habitats act as environmental filters to butterfly species, but that neutral processes dominate after environmental filtering.</div></div>","PeriodicalId":54264,"journal":{"name":"Global Ecology and Conservation","volume":"59 ","pages":"Article e03561"},"PeriodicalIF":3.5,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143714364","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}

Smaller and more isolated páramo units in the Nariño-Putumayo Páramo District could develop avian communities shaped by nestedness patterns, possible species replacement, and local extirpation.

This might have contributed to the global decline of shorebird populations that led even to local extinctions in a number of species. Here we aimed to investigate relationships among attributes of grazing and breeding population of shorebirds applying standardised surveys at ten sample sites in Hortobágy, the largest interconnected alkali steppe of Europe.

In several species, we found positive relationships between the number of breeding pairs and the size of open water surface. 81 % of breeding populations bred in sample sites where the extent of open water exceeded 10 ha.

Threats generally act on two distinct elements of their life-history, either breeding at terrestrial colonies, or during the nonbreeding season while at sea foraging and migrating. Moult is often overlooked as another critical life-history component that can determine their vulnerability and exposure to threats at sea. Using 13,092 geo-referenced citizen-science photographs from publicly available and private collections, we scored primary feather moult for 6 gadfly petrel species (<em>Pterodroma</em> spp.) as a representative and understudied group of tubenosed seabirds. To investigate environmental conditions of areas where gadfly petrels moult, we quantified moult phenology for 1336 individuals. Moult activity overlapped with breeding and/or migration in all species, a surprising result, as these processes are temporally offset in many other birds. Sea surface temperature predicted moult activity in most species, with the probability of active moult being greater in areas with higher sea surface temperatures. Higher sea surface temperatures are associated with lower marine productivity, so gadfly petrels undergo moult in less productive waters than they occupy at other times. This possibly reflects avoidance of adverse conditions that disproportionately affect gadfly petrels with compromised plumage. Our findings indicate that moult is important for understanding tubenosed seabird distributions, and affects exposure to substantial threats. Knowledge of how moult informs threat exposure can refine best-practice in conservation planning for seabirds, by informing key management tools such as designating marine protected areas.</div></div>","PeriodicalId":54264,"journal":{"name":"Global Ecology and Conservation","volume":"59 ","pages":"Article e03558"},"PeriodicalIF":3.5,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143706346","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}
