But evaluating the feralization progress of re-introduced “wild” animals requires concise and quantitative indicator(s) to integrate traditional assessments on self-sustainability and reproduction. A fecal ARGs’ profiling was conducted for Przewalski’s horses, an extinct flagship herbivore, in Xinjiang, China from the Breeding Center (captive), Tianshan Wildlife Zoo (semi-captive), and Kalamaili Nature Reserve (re-introduction) with Mongolian wild asses serving as a reference in the shared Kalamaili range. Over 60 ARGs were quantified across 6 samples at each site for Przewalski’s horses while 46 ARGs for Mongolian wild asses. The re-introduced Przewalski’s horses had significant losses of fecal ARGs in sharing number and relative abundance in comparison to the captive ones. The re-introduced Przewalski’s horses had complex internal connections among the quantified fecal ARGs in expression intensity (average relative abundance per quantified ARGs by antimicrobial category) and even more significant external connections with Mongolian wild asses than with captive horse. Overall, the re-introduction of Przewalski’s horses achieved notable and progressive success in feralization. Tetracyclines resistance genes (Tetra-RGs) alone, with full quantification frequency, could quantitatively characterized this achievement. Ratio of Tetra-RGs to aminoglycosides resistant genes (Amino-RGs) would differentiate the feralization progress with orders of magnitude, for the re-introduced Przewalski’s horses at 279 and the captive one at 11.7, against Mongolian wild asses at 0.86 in this study. The two ARGs-based indicators might be applicable to quantify feralization progress in re-introduction of other captive endangering or extinct animals with validations.</div></div>","PeriodicalId":54264,"journal":{"name":"Global Ecology and Conservation","volume":null,"pages":null},"PeriodicalIF":3.5,"publicationDate":"2024-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142535645","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 InVEST and PLUS models were utilized in this study to evaluate the dynamics of carbon sequestration and biodiversity in the Chishui River Basin, Southwest of China. By integrating the factor detection of the Geographic Detector and the Multi-scale Geographically Weighted Regression (MGWR) model, this study identified the key drivers affecting trade-off and synergy and revealed their spatial heterogeneity. Furthermore, utilizing the interaction detection of the Geographic Detector and the Geographic Cross-Convergence Mapping (GCCM) model, this study analyzed the interaction direction and interaction intensity among key drivers. The results showed that: (1) From 2012–2035, the total values of carbon sequestration and biodiversity exhibited an overall increasing trend, with 58.49 % of the area showing trade-off effects, 23.86 % showing positive synergy, and 17.65 % showing negative synergy. (2) Elevation, slope, topographic relief, temperature, and land use intensity were identified as key factors influencing trade-off and synergy, and these factors displayed significant spatial heterogeneity. (3) When multiple drivers interacted, their explanatory power for trade-off and synergy increased significantly. The interaction patterns among drivers presented a “topography➙climate↔human activity↔distance➙soil” structure, where human activity interacted bidirectionally with other factors, with the strongest interaction occurring between climate factors and human activity. This study advanced the understanding of the driving mechanisms behind trade-off and synergy through MWGR and GCCM model. Based on the supply-demand theory, a synergistic management framework was proposed to emphasize the “pattern-process-service-feedback” nexus.

Competition and hybridization with invasive Italian lizards, <em>Podarcis siculus</em>, have been proposed as a driver of the shrinkage of Aeolian lizards, still the mechanisms underlying their decline remain poorly resolved. We used observations of behavioral encounters, combined with morphological data and robust species identification based on genomics, to test whether agonistic interactions with the invasive Italian lizard can explain the competitive exclusion and rapid decline of the native Aeolian lizard while accounting for hybridization. Invasive lizards were larger, with larger heads, and showed higher bite tendency against neutral items. In agonistic encounters between males, Aeolian lizards received more attacks and escaped more frequently than invasive males. The performance of Aeolian males was particularly poor in interspecific encounters. Genomic data verified that tested individuals were all pure <em>P. raffonei</em> or <em>P. siculus</em>, with a single hybrid individual detected. The strong competitive advantage of invasive males can allow them monopolizing territories, potentially hampering the reproduction of both native males and females, thus resulting in a mechanism of sterilizing interference. Reproductive interference competition mediated by spatial exclusion might be an unappreciated process determining rapid decline in endemic species.

We aimed to map these areas at a high spatial resolution (10-m pixels) and analyse their role in maintaining lateral connectivity essential for fish diversity. Using synthetic aperture radar data from Sentinel-1 combined with deep learning algorithms, we produced high-accuracy flood maps to assess landscape connectivity between rivers and floodplains. Our methodology included creating a ground truth dataset with the Normalized Difference Water Index and integrating high-resolution optical data for model training, overcoming challenges of cloud coverage and dense vegetation. Our predictive model achieved high accuracy (mean pixel accuracy = 97 %) and consistently predicted 4801 km² of surface water, with only 3 % (130 km²) being seasonally flooded areas over four years. The Caquetá, Bajo Marañón, Napo, and Pastaza watersheds accounted for nearly 60 % of the flooded areas, highlighting their ecological importance. Connectivity analysis in three areas of interest within the NMF ecoregion revealed important seasonal and interannual fluctuations in hydrological connectivity due to changes in flooded patch characteristics. Reductions in the number and flooded patch area during low water seasons increased the distance between patches, leading to a disconnection between flooded areas, channels and rivers. Despite hydrological fluctuations, certain patches maintained consistent flooding, critical for lateral connectivity and sustaining aquatic biodiversity. These seasonally flooded areas act as connectors, influencing patch dynamics and connectivity with tributaries. Seasonal and interannual variations in hydrological connectivity are crucial for sustaining fish diversity. Conserving dynamic floodplains supports migratory fish life cycles and biodiversity.

These animals are directly linked to human well-being, and declines in their populations can even have adverse effects, such as increasing the need for pesticides in regions where natural insect control is reduced. The seed dispersal conducted by bats is fundamental for maintaining neotropical biodiversity, as it supports habitat regeneration and the propagation of various plant species. Moreover, the role of these dispersers is enhanced due to their ability to inhabit a variety of environments, from natural forests to anthropized areas. However, the conversion of natural forests into agricultural production areas, as well as urbanization, has affected the structure of mutualistic networks between bats and plants. In this context, the objective of this study was to identify the pattern of seed dispersal by bats of the Phyllostomidae family in an anthropized landscape of the Brazilian Amazon. Data collection was conducted in different areas of natural forest, cocoa cultivation, and urban areas in the municipalities of the States of Pará.

The most traded species in Guyana included paca, white-lipped peccary, deer, tapir and capybara and a total of 38.46 % (5 out of 13) of the taxa being traded is classified as threatened of extinction.

Access to improved preservation methods (e.g. freezers) and motorized transportation options (eg.: boat with engines and vehicles) significantly influence higher volumes of wildmeat traded. The economic growth anticipated in Guyana is expected to boost population growth and, by the same time, wildmeat demand in urban areas. Concomitantly, with improved infrastructure and increased access to electricity, wildmeat provision will be facilitated across a wider catchment area.
