Jellyfish blooms restructure plankton dynamics and trophic linkages in coastal waters
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Jellyfish blooms are increasing globally in frequency and intensity, introducing complex ecological interactions, yet the mechanisms by which they alter ecosystem structure remain poorly characterized due to a lack of sustained field observations.

Conservation Biology, EarlyView.Abstract The Natura 2000 (N2K) network of protected areas is one of the main tools for area‐based conservation in the European Union (EU), yet its role in preserving plant biodiversity requires better understanding. We examined data kept in the European Vegetation Archive from over 1.2 million vegetation plots and obtained over 14.2 million plant ...

全球能源互联网宽频振荡紧急控制是保障风电系统安全运行的“兜底”措施之一。由于风电系统非线性强度大及运行工况多变，难以建立宽频振荡在线风险评估的解析模型。为此，提出了基于数据驱动的宽频振荡风险在线评估方法及紧急控制策略。首先，设计了能够应对宽频振荡多模态和时变特征的宽频相量检测算法，为后续宽频振荡特征评估提供数据支撑；其次，利用最大李雅普诺夫指数作为宽频振荡动态演化趋势的量化指标，并根据风电机组模态阻抗的负电阻效应在线辨识宽频振荡源；然后，融合宽频振荡特征辨识结果，提出宽频振荡风险在线评估策略 ...

Success of restoration strategies in preventing extirpation of 2 critically endangered coral species
Conservation Biology, EarlyView.Abstract An unprecedented marine heatwave in 2023 caused widespread coral bleaching and mortality throughout the Caribbean. In the Florida Keys (USA), 2 foundation species, elkhorn coral (Acropora palmata) and staghorn coral (Acropora cervicornis), were severely affected.

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.

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

Conservation Biology, EarlyView.Abstract Consumer demand for ivory perpetuates the unsustainable and illegal killing of African elephants and other wildlife species. Interventions that aim to change consumer behavior are increasingly recognized as a crucial element of demand management. However, poor design and implementation have limited their effectiveness.
