Biodiversity‐driven spatial conservation planning to delineate temporally stable regions
Conservation Biology, EarlyView.Abstract The accelerating loss of biodiversity underscores the critical need for effective conservation strategies, particularly in the face of climate change and anthropogenic pressures. We devised a conservation planning framework that adopts a temporal stacking approach to species distribution models and landscape connectivity analyses. These models

Assessment Research of Coastal Ecosystem Carrying Capacity: a Case Study in Guangxi Coastal Area [PDF]
, 2015 海岸带自然资源充足，环境条件优越，支撑着沿海地区社会经济发展。然而，海岸带由于受到来自陆域和海洋的强烈相互作用，成为了最易受到环境影响而变化的生态敏感区和脆弱性较强的生态系统。相比自然的影响，人类活动是海岸带生态系统受到的最主要干扰源。随着近年来海岸带地区人类开发活动强度的持续增加，海岸带出现了资源日渐匮乏、环境质量下降、生态风险升高等一系列问题，海岸带生态系统呈现出一定的退化趋势。开展海岸带生态系统承载力评价研究，有利于协调自然、经济、社会之间的发展关系，为制定合理的海洋发展战略提供科学依据和技术支撑。

Scenarios and strategies for future‐proofing ecosystem management under climatic novelty
Conservation Biology, EarlyView.Abstract Climate change is driving unprecedented declines in dominant, habitat‐forming foundation species across marine and terrestrial ecosystems globally. As climatic novelty becomes the norm, ecosystem reassembly will become increasingly common. Predicting and understanding these transitions, and their implications for future ecosystem functioning ...

油茶籽淀粉的结构与体外模拟消化特性研Structure and digestion property in vitro of Camellia oleifera starch
Zhongguo youzhi为促进油茶籽淀粉资源的开发利用，采用“碱提+酶解”工艺从油茶籽粕中提取油茶籽淀粉，并以市售玉米淀粉和马铃薯淀粉为对照，比较其结构和体外消化特性。结果表明：本工艺所得油茶籽淀粉的提取率为64.25%，纯度为92.66%；与市售玉米淀粉、马铃薯淀粉相比，油茶籽淀粉呈圆球形或椭球形，颗粒更小；油茶籽淀粉为典型的A型淀粉，其长程结构不稳定，相对结晶度更低；油茶籽淀粉的短程有序程度与市售玉米淀粉、马铃薯淀粉相似，但双螺旋度数更低；油茶籽淀粉抗性淀粉含量（16.91%）更高。综上 ...

Island Ecosystem Assessment：A Case Study of Baishashan Island in Zhoushan, Zhejiang Province [PDF]
, 2015 我国是海洋大国，岛屿众多，海岛是我国国土的重要组成部分，海岛蕴藏着极为丰富的生物、矿物、能源、港口、旅游、生态环境资源等，海岛地理位置特殊，在维护国家领土完整、维护海洋权益等关系到民族生存与发展等方面具有不可估量的社会、经济、科研、生态和政治及军事价值。近年来，国家高度重视海岛开发与保护，对海洋强国、海洋战略、海洋产业、海洋资源作出了一系列决策部署。 目前我国在海岛开发、保护和管理中存在诸多问题，许多海岛开发是在未开展生态调查，缺乏开发规划的情况下开展的，导致海岛生态系统遭受破坏或生态功能下降 ...

Perceived costs as drivers of wildlife management preferences in rural Tanzanian communities
Conservation Biology, EarlyView.Abstract Effectively managing human–wildlife interactions is crucial for fostering coexistence on shared landscapes. Management options are most effective when aligned with the preferences of people directly affected by wildlife, yet little is known about how socioecological factors influence these preferences.

Drivers of bat researchers’ intent to adopt field hygiene practices
Conservation Biology, EarlyView.Abstract Infectious disease is a growing threat to wildlife, with zoonotic transmission most likely at the human–wildlife interface. One underappreciated activity at this interface is fieldwork with wild animals, but associated risks can be mitigated through field hygiene (FH) practices, such as using personal protective equipment and other appropriate

Theory And Practice Research on Marine Ecological Rehabilitative Justice---A Case Study of Marine Oil Spill Ecological Damage [PDF]
, 2015 随着经济的持续快速发展以及人类需求的不断膨胀，人类从自然界获取资源、能源的领域已经从陆地延伸到了海洋，由此给海洋生态带来的损害也是不容忽视的。新工业发展使石油成为国家战略安全的重要标志，远洋石油运输和海上石油钻井平台蓬勃兴起，所造成的海洋石油污染更是触目惊心，这不仅给国家和个人造成重大经济损失，而且还会给海洋生态环境和自然资源带来极大的危害。我国关于海洋生态损害追偿和救济的法律性规定只有《海洋环境保护法》第90条第2款。该款虽然规定海洋环境监管部门可以提起针对破坏海洋生态的索赔诉讼 ...
