Conservation Biology, Volume 40, Issue 1, February 2026.Abstract Urgency to save species from extinction has prompted increased investment in law enforcement in protected areas. To date, such law enforcement has largely focused on increasing costs and reducing opportunities for offending. However, these resource‐intensive approaches are not always effective and can contribute to conflict between people and ...

野生动物学报, 2013 蟒蛇是中国产的最大的蛇之一,是国家Ⅰ级重点保护野生动物,海南坡鹿是中国特有的国家Ⅰ级重点保护野生动物,它们和其他野生动物及其栖息地组成了海南大田保护区区域生态系统,蟒蛇是处于生态系统食物链顶端的捕食者,要更好地保护海南坡鹿,不能仅针对坡鹿物种本身进行保护,还要对这一生态系统中的其他野生动物和栖息地进行保护。本研究结合有关调查数据分析保护区蟒蛇的种群动态以及空间分布规律,同时探讨蟒蛇的捕食行为对海南坡鹿种群的影响,可为制定有效的、科学的系统保护对策和措施提供依据。

Underrepresentation of bats in Africa's protected areas
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract Biodiversity is severely threatened globally, with habitat loss and other human pressures accelerating species extinctions. Protected areas (PAs) are a critical conservation tool; however, their effectiveness in safeguarding many taxa, such as bats, remains unclear.

Discussion on Coastal Building Setback of Coastal Small Towns [PDF]
, 2016 本文以海岸带小城镇海岸线建筑后退距离为研究对象,在借鉴国内外相关经验的基础上,提出以多因素分析法代替单一因素分析法确定海岸线建筑后退距离的基本思路,并重点探讨了不同海岸底质下多因素分析法对于海岸线建筑后退距离的影响。文章以福建省若干海岸带小城镇为例,就海岸线建筑后退距离的确定方法初步进行了实例研究。On the basis of relevant experience at home and abroad, the paper takes the coastal building setback of ...

Genetic origins and climate‐induced erosion in economically important Asian walnuts
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract The global climate is undergoing unprecedented changes, posing significant threats to species persistence. However, the spatiotemporal impacts on genetic diversity remain poorly understood, hindering species conservation and management. Walnuts, generally referred to as Juglans regia and J. sigillata, are economically vital in Asia, but little

Preliminary studies on effects of restored mangroves on coastal soils [PDF]
, 2004 初步研究了不同林龄的再植红树林对海岸湿地土壤理化性质的影响。结果表明,红树林恢复对深层土壤(20～25cm)的影响强于表层(0～5cm);与光滩相比,红树林恢复对表层土壤的氧化还原性无显著影响,但导致20～25 cm土层氧化性增强;再植红树林对土壤营养盐有明显吸收作用,其中NH4+-N含量显著高于NO2--N 和NO3--N,为主要吸收营养盐,PO43--P含量虽与IN相当,但红树林对P的吸收并不明显;随着红树林恢复时间的延长(林龄增加),20-25 cm土层的pH值显著下降,红树林酸化作用增强 ...
