Threats to and management of Natura 2000 protected areas relative to agricultural practices
Conservation Biology, EarlyView.Abstract The Natura 2000 (N2K) network combines biodiversity protection and socioeconomic targets. Human activities, such as agricultural practices, can affect biodiversity in N2K sites in diverse ways. Limiting activities with negative impacts while enforcing land management that supports biodiversity is crucial for effective conservation.

A study on adaptable system model and its application to desktop publishing system [PDF]
, 1995 In 1948 the term "information" sprang from the literature world, and was adopted in the logic world. Concurrently and by chance, C. E. Shannon constructed a historic quantitative information formula, "information entropy" [144], whiile N. Wiener proposed

When and why to give shorebirds a head start
Conservation Biology, EarlyView.Abstract Headstarting is a translocation technique involving the hatching or rearing of wild eggs or young in captivity and the release of those individuals back to the wild at or before independence. It has been trialed as a conservation intervention for shorebirds over recent decades to improve the population trend of target populations by increasing

Nitrogen Transports and Transformations in Mangrove Sediments using Nitrogen Isotope Techniques in China [PDF]
, 2012 人类活动对生态系统的影响日益扩大，过量施肥、化石燃料的燃烧等引发的氮(N)负荷迅速增加。陆地生态系统过剩的N通过流域汇集至河口和海岸，威胁着海洋生态系统的健康。目前，全球N循环正致力于揭示河口和海岸地区N的源汇格局及主导机制。红树林湿地广泛分布于热带、亚热带河口和海岸地区，作为陆源营养盐入海过渡带，在缓解陆源N输入方面扮演着重要角色，成为了研究的热点。 本研究利用N稳定同位素技术，将现场培养与室内模拟培养相结合，揭示了我国东南沿海典型河口和海湾红树林湿地沉积物总氮沉积、固氮作用、反硝化作用 ...

In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle
Conservation Biology, EarlyView.Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

Research on the Impact of China's Asset Returns on the Volatility Index [PDF]
, 2016 波动性溢出问题一直宏观经济学家和决策制定者所密切关注的研究话题。现有的研究大多从宏观的视角证实了经济波动的传染效应和具体的传染渠道：即一个国家的经济波动会通过国际贸易与资本流动的方式传递到其他国家。但是，现有研究的时间窗口普遍集中在2008年以前，而且缺乏外国来华投资盈亏如何影响出资国资本市场波动的经验证据。而事实上，随着中国经济的高速发展以及来华投资规模的不断扩大，中国对全球金融市场的影响已不容忽视。那么，作为外商投资第一大目的国，中国国内资产收益下降所造成的美国在华投资利润减少甚至亏损 ...

Lessons from an eradication under multiple constraints of an island rat population of record density
Conservation Biology, EarlyView.Abstract Invasive rats threaten island biodiversity, disrupting ecosystems and endangering native species. Although rat eradication has succeeded on many islands, tropical islands present unique management challenges. Strict regulations and financial constraints on some tropical islands further limit proven eradication methods, complicating rodent ...

Distribution, scale, and drivers of mass mortality events in Europe's freshwater bivalves
Conservation Biology, EarlyView.Abstract Mass mortality events (MMEs) are decimating populations and compromising key ecosystem functions around the globe. One taxon particularly vulnerable to MMEs is freshwater bivalve mollusks. This group has important ecosystem engineering capacities and includes highly threatened and highly invasive taxa.

An Equilibrium Analysis under Cobb-Douglas Production and Utility Functions [PDF]
The equilibrium analyses under the classical growth framework mainly concern production processes so far and the utility-maximization of consumers is left out of consideration.

Conservation Biology, EarlyView.Abstract Wildlife reintroductions are socioecological processes entailing the intentional movement of organisms by people. In animal reintroductions, there is growing recognition of the importance of human dimensions and efforts to integrate these into reintroduction projects. To conceptually reframe reintroductions as processes of renewed coexistence (
