Informing spatial conservation prioritization with species’ traits
Conservation Biology, EarlyView.Abstract New Guinea, the most botanically diverse island on the planet, is the location for one of the boldest conservation initiatives. The Manokwari Declaration aims to achieve 70% conservation designation for the Bird's Head Peninsula. This is 40% higher than the 2022 Global Biodiversity Framework target.

, 2015 海岸带区域的污染具有内容广泛、状况复杂和管理决策难度较大等特点。由于海岸带环境中的化学污染物往往以混合形式存在,因此单一化学品高剂量暴露下的生态毒性研究结果难以适用于环境中低剂量混合物的生态毒理效应诊断及风险评价。传统的风险评价体系多是在实验室模拟条件下以单一物质的急性或慢性毒性试验为依据,往往很难正确反映实际环境中污染物混合存在时的生态行为及环境危害。随着技术的进步和人类认识能力的进一步提高,研究者们已经聚焦于发展数学模型用以预测及评价化合物的联合毒性 ...

Differences in characteristics between naturalized threatened plants and other threatened plants
Conservation Biology, EarlyView.Abstract Many non‐native plant species introduced by humans have become naturalized. At the same time many species are threatened in their native range. However, the number of plant species threatened in their native range that are naturalized elsewhere remains unknown.

野生动物学报, 2017 采用分层随机抽样的方法对全国开设野生动物相关专业的6所高校的600名学生进行问卷调查。分析结果显示,野生动物相关专业学生生态道德素质总体处于“良好”水平,其中生态道德知识水平的平均得分为(3.60±0.50),生态道德意识为(4.15±0.62),学生生态道德行为平均分相对偏低,为(3.47±0.50); 但学生的生态道德教育需求未能得到很好地满足,教育状况处于“一般”水平(3.39±0.38),表明学生的生态道德教育还需进一步加强。生态道德素质与生态道德教育水平与学生的性别、年级有关。针对调查结果 ...

Method and Practice in Setting Coastal Construction Setback Line: A Case Study in Longhai [PDF]
, 2016 海岸带地区由于其富饶的资源、优美的环境、优越的地理位置和独特的海陆性质，使其成为人类活动最密集和最活跃的区域。然而人类为了享受海岸带地区为其生存和发展带来更大的经济利益，一方面越来越多的建筑物和基础设施出现在距海岸线更近的地方，海岸侵蚀以及自然灾害已经严重的威胁到沿海地区人类生命财产的安全；另一方面由于人类活动的加强，海岸带的生态系统遭到破坏，生态环境日趋恶化。如何协调海岸地区的和谐发展，实现海岸带经济发展的可持续性已经成为当今社会最关注的热点问题之一 ...

Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Research on Lao Zi's scientific thought [PDF]
, 2016 老子科学思想对中国传统文化影响至深。老子的《道德经》是中国历史上较早论及科学思想的历史文献。《道德经》之中蕴涵了丰富的科学思想，在先秦时期的典籍之中能如此全面而又细致地探讨宇宙、自然等科学问题实属难得。在科学技术比较落后的春秋战国时期，这部经典之作具有重要的研究价值。 只可惜，海内外学者对《道德经》中所蕴涵的科学思想一直未给予应有的重视。研究视角主要集中在老子的政治学、美学、管理学、医学等领域。虽然很多学者已经从自然观、科学观等角度研究老子的思想，已然踏及老子科学思想这片肥沃的土地，但是在研究深度 ...

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas
Conservation Biology, EarlyView.Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

Conservation Biology, EarlyView.Abstract In the western United States, conservation practitioners are increasingly working with private landowners to restore habitat for North American beavers (Castor canadensis) and to use nonlethal mitigation techniques when beavers damage crops and infrastructure.

Shuitu Baochi Xuebao, 2003 生态水文学(Ecohydrology)是近10年来发展起来的一门新兴边缘学科,主要从流域尺度上研究水文与生态之间的相互关系,探索实现流域生态平衡与水资源可持续利用的新途径.在我国,近年来生态水文学已经引起学术界的高度重视,但研究工作尚处于起步阶段.国际上,虽然美国、欧洲、加拿大等已经开展了比较多的研究,但对于生态水文学的定义等基本问题尚存在不同的看法.在简述生态水文学发展概况的基础上,对生态水文学及有关基本概念进行分析和讨论,包括生态水文学的定义、生态系统途径、生境质量及其要素、影响生态整体性的环境因素、
