This study combined up to four years of field measurements (2–4 years for litterfall, 1 year for fine root stocks, and 2 years for fine root production and mortality) from twelve 0.02–0.09-ha stands in Gwangneung Experimental Forest to investigate the relationships between litter and fine root variability and stand topographic, structural, and edaphic features.

We also use conflict-related mortality records (2001–2018) to model the spatial risk of fatality for lions from anthropogenic mortality, identify the major predictors of mortality, and map potential hotspots of anthropogenic mortality across the GEL. There were 698 conflict related lion mortalities reported between 1980 and 2018 with an average annual mortality of 22 lions (SE 16), although these are likely underestimates as not all anthropogenic mortality may have been reported. Conflict-related anthropogenic mortality of lions peaked during the cold dry season when availability of water was limited and game movements were concentrated around perennial waterpoints, and was greater in areas with localized livestock populations and low woody cover. Our landscape risk analysis revealed that areas bordering ENP function as ecological traps with certain pockets within the GEL acting as hotspots of conflict-related mortality. The majority of the conflict-related lion mortality was reported from commercial freehold farms reflecting Namibia’s colonial history and land ownership. Our findings suggest that mitigation measures to reduce human-lion conflict at the interface of ENP and other protected areas in Sub-Saharan Africa need to consider both ecological and cultural factors to have maximal impact.

The prevailing view in population genetics is that species attempt to avoid the harms of inbreeding. We speculate that sometimes individuals do not reject mating requests from relatives when choosing mates. Moose (<em>Alces alces cameloides</em>) in the Greater Khingan Mountains (GKM) of China is a first-class key protected species. It represents the southernmost distribution of moose globally and serves as a thermosensitive species of global significance. Based on the state of moose in China, we used a non-invasive sampling method to conduct a series of studies on genetic diversity and inbreeding. The mitochondrial and nuclear genetic diversity of moose in this area are at a moderately high level worldwide, with good individual genetic quality, a high level of overall genotype heterozygosity. The Bayesian gene flow level indicates gene exchange between local populations. Molecular pedigrees revealed instances where individuals mated with their offspring or even grandchildren. The relatedness coefficient (<em>r</em>) between moose mating pairs were significantly higher than those of random mating. Therefore, there is no evidence that individuals in the GKM avoid inbreeding, and under these circumstances, there has not been a negative impact on genetic diversity of the moose population, as well as the genetic quality and genotype heterozygosity of offspring. In the context of future climate change and human activities, we need to closely monitor the long-term impact of this mating choice on the survival of the GKM moose population and promptly develop corresponding conservation and management strategies.</div></div>","PeriodicalId":54264,"journal":{"name":"Global Ecology and Conservation","volume":"59 ","pages":"Article e03513"},"PeriodicalIF":3.5,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143549318","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}

Despite its conservation significance, there has been a lack of comprehensive scientific study on the population status and endangerment mechanisms of this genus. In this study, using the multiple methods like diameter at the breast height (DBH, acquiring from the field) instead of age classes, calculation in the quantity between each pair of adjacent DBH classes (laboratory analysis, the same below), static life table compilation, population prediction, and artificial pollination, we investigated the population structures, dynamics, and flowering traits of these above-mentioned three endangered <em>Sonneratia</em> plants. Our findings revealed that <em>S. × hainanensis</em> and <em>S. × gulngai</em> populations had a critical deficiency in young individuals, indicating poor self-renewal capacity and a likely population decline in the future. In contrast, <em>S. ovata</em> showed a high proportion of young individuals, suggesting a potential for population increase. This divergence in population dynamics correlates with differences in flowering traits among the mangroves. <em>S. ovata</em> exhibited the highest pollen viability, fruit set rate, and average seed count per fruit. Consequently, our study suggests that the flowering traits of these <em>Sonneratia</em> plants are pivotal to their conservation status. To address the current population challenges, we recommend the promotion of artificial pollination, the preservation of ex situ germplasm resources, and the enhancement of in situ conservation efforts.
