Risk reduction, rangeland use, and the future of human–carnivore coexistence
Conservation Biology, EarlyView.Abstract Efforts to reduce livestock losses to large carnivores are widely regarded as essential for promoting human–carnivore coexistence. Predator‐proof enclosures, compensation programs, improved livestock guarding, and real‐time predator alert systems can reduce depredation and retaliatory killing while enhancing pastoralist livelihoods.

論健康保險之保前疾病、追溯保險與被保險人之善意 ― 相關實務見解綜合評析 Pre-existing Conditions in Health Insurance, Retrospective Insurance and Good Faith – Comments on Relevant Court Rulings [PDF]
Kējì Fǎxué Pínglùn, 2009 依照保險法第127條，健康保人對於被保險人在訂約時已經存在的疾病不負保險責任。所以如果被保險人帶病投保，保險人通常拒絕給付保險金。不過，許多法院判決表示，如果訂約時該疾病無外觀上可見之症狀，而被保險人並不知道自己罹患疾病者，保險人不得免責。依照判決內容及文獻說明來看，此項見解似乎是以同法第51條第1項（追溯保險）為推論依據。但在我國法上，疾病即為健康保險的保險事故，對於訂約前已經發生的保險事故，如果契約雙方當事人並未約定將承保期刊提前，似乎不能以追溯保險之原則使保險人對該項疾病負責 ...

Conservation Biology, EarlyView.Abstract Global farmland biodiversity is declining rapidly, threatening both natural ecosystems and agricultural production. Although agri‐environmental schemes incentivize farmers to adopt environmentally friendly measures, the spatial mismatch between their local implementation and the landscape‐scale habitat requirements of farmland species has been

A framework for integrating resilience indicators into risk assessments
Conservation Biology, EarlyView.Abstract Globally, ecosystems are increasingly threatened by climate change and human pressures, yet ecosystem risk assessments predominantly emphasize exposure to stressors while overlooking intrinsic ecosystem resilience—the capacity to absorb and recover from disturbances.

Integrating biodiversity protection into emergency management
Conservation Biology, EarlyView.Abstract Megafires have emerged as a considerable threat to biodiversity conservation worldwide. The biodiversity‐focused response and recovery actions that occurred during Australia's 2019/2020 Black Summer bushfires demonstrate that it is possible to protect biodiversity alongside human life and property during disasters.

中国油料自给率及其影响因素研究China′s oilseeds self-sufficiency rate and its influencing factors
Zhongguo youzhi油料自给率是衡量油料产业安全的重要指标，对其进行科学测算有利于国家油料生产和贸易格局的优化调整。利用2002—2022年植物油料和食用植物油产量、进出口量等宏观统计数据，通过改进的自给率计算公式，对我国油料真实自给率进行测算，并利用灰色关联分析方法从生产端、消费端和贸易端3个角度对影响油料自给率的11个指标进行分析。结果发现：我国油料真实进口量已于2012年进入“亿吨”时代，油料自给率从2009年开始跌至40%以下，个别年份一度跌至约30%；生产端、消费端和贸易端与油料自给率均存在中等强度关联，其中 ...

Integrating migratory connectivity data into the conservation of Australian sharks and rays
Conservation Biology, EarlyView.Abstract Understanding migratory connectivity is important for conserving highly mobile marine species facing escalating threats. Establishing baseline information on migratory connectivity is necessary for identifying species and regions requiring transboundary cooperation for their conservation.
