Seasonality is an important factor affecting food resources and other habitat conditions, influencing spatial distribution dynamics. This study used data from 110 camera traps in the Inner Mongolia Hanma National Nature Reserve, China, from 2016 to 2021 to estimate the population densities of lynx (<i>Lynx lynx</i>) and three ungulate prey species, and analyzed them using Random Encounter Models. We used generalized linear mixed models to examine the effects of environmental factors on the spatial density distribution of prey and their impacts on the lynx spatial density distribution in cold and warm seasons. The results showed that during the warm season, roe deer (<i>Capreolus pygargus</i>) spatial density distribution was influenced by forest swamps and birch forests; in the cold season, fallen logs, shrub swamps, and mixed forests most significantly impacted distribution. Moose (<i>Alces alces</i>) population density was higher near shrub swamps during the warm season, but higher in areas with higher <i>Betula fruticosa</i> shrub abundance and fewer fallen logs in the cold season. Musk deer (<i>Moschus moschiferus</i>) population density was higher closer to roads, birch forests, and mixed forests in both warm and cold seasons, and either higher (cold season) or lower (warm season) <i>B</i>. <i>fruticosa</i> shrub abundance. Except for moose in high-elevation areas during the cold season, the three ungulate species inhabited low-elevation areas during warm and cold seasons.

We surveyed BSG members to gauge their perception of threats to bears in their local area, understand what actions they had undertaken to reduce these threats, and document their opinions of the effectiveness of their actions and the chief constraints encountered. Members indicated that the types and severity of threats to bears varied geographically and by species. Loss, degradation, or fragmentation of forested habitat was rated the highest threat for all species, and among species, was ranked most severe for sloth bears (<i>Melursus ursinus</i>) on the Indian subcontinent. Exploitation for trade (illegal hunting) was viewed as the most threatening to sun bears (<i>Helarctos malayanus</i>) and Asiatic black bears (<i>Ursus thibetanus</i>) in Southeast Asia. Andean bears (<i>Tremarctos ornatus</i>) in South America were especially prone to mortality from human–bear conflicts. Future impacts of climate change, although difficult to assess, were considered an impending high threat for Andean bears and brown bears (<i>U. arctos</i>) at high elevations in Asia. Although BSG members focused most on the “Assess” phase of IUCN's conservation cycle (Assess, Plan, Act, Communicate, Network), &gt; 80% had also been involved in direct actions (Act phase) aimed at improving or protecting habitat (60%), reducing conflicts (54%), and/or reducing illegal exploitation (33%). Members were more apt to act when they perceived a threat to be high. Their actions also appeared to be influenced by previous success and available resources. Moreover, since two-thirds of BSG members (higher in Asia) did not self-identify as bear specialists, their conservation actions were not necessarily targeted at bears. BSG members considered conservation to be most effective in North America and least so in Asia, where resources, human capacity, and government support were lacking.

We developed a burrow-based monitoring approach relying on reconnaissance walks across grids coupled with landscape-scale modeling based on remote sensing data to fill these knowledge gaps for the species. From 2018 to 2021 we detected a total of 248 burrows across sites in Hong Kong, with active usage of a subset of these verified through camera trapping. The burrow-level analysis revealed that burrows tended to be further away from the coast and at higher elevations than random. Burrows were also found in grasslands, shrublands, and mature forest in roughly equal proportions. For the grid-level analysis, we found burrows were more numerous further away from the coast, when areas had an east-facing aspect, and with lower proportions of shrubland and urbanization. Both scales of the analysis identified distance to coast as the most important factor suggesting that core natural habitats and undisturbed/protected areas are key for pangolin persistence in Hong Kong. We found no evidence of human hunting for pangolins but dogs were recorded at an active burrow. The rare and elusive nature of <i>M. pentadactyla</i> can complicate monitoring efforts but our results here demonstrate how burrow-based approaches, particularly when leveraged in landscape analysis and remote sensing (and LiDAR especially), can be used to provide key conservation and wildlife management insights.</p>","PeriodicalId":100680,"journal":{"name":"Integrative Conservation","volume":"5 2","pages":"205-216"},"PeriodicalIF":0.0,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/inc3.70081","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148358248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Transmission electron microscopy revealed that the infected cortical cells of symbiotic protocorms lacked distinct organelles and were colonized by fungal hyphae. The fungal hyphae penetrated, proliferated, and were subsequently digested within the protocorm cells, indicating that symbiotic protocorms exhibit a heterotrophic life and efficiently utilize fungal hyphae to support their growth and development. In contrast, asymbiotic protocorms contained abundant chloroplasts and amyloplasts, suggesting their capacity for autotrophic growth dependent on exogenous nutrients to sustain protocorm development.

For this, we (1) describe seasonal foraging dynamics and (2) evaluate the use and selection of food plants. In a gradient of urbanization in northwestern Patagonia, Argentina, we surveyed foraging parakeets, and documented plant resource availability and phenology throughout the year. Parakeets consumed three times as many introduced as native plant species in urban environments, mostly during winter, when native food availability is scarce. Whereas the opposite pattern occurred in natural areas. Resource use and selection varied with environment and sampling scale, including the selection of native species in urban areas and introduced species in natural environments. By revealing broad patterns of plant–animal interactions across contrasting environments, we illustrate how urbanization reshapes habitat and resource use in a behaviorally plastic species. We also provide phenological data relevant to a range of co-occurring species. Our findings underscore the trade-offs associated with urbanization for wildlife.
