Justice in coexistence: Pastoralism and large carnivores on the Qinghai‐Tibet Plateau
People and Nature, EarlyView.Abstract The conflict between livestock husbandry and large carnivore conservation presents significant challenges in grassland ecosystems worldwide. Achieving sustainable coexistence among herders, livestock and large carnivores requires reconciling diverse perspectives and interests through equitable, inclusive and fair processes that address both ...

A link between increased temperature and avian body condition in a logged tropical forest
Conservation Biology, EarlyView.Abstract The combined effects of anthropogenic disturbances, such as logging and climate change, remain poorly understood; yet, they are the main threats to tropical biodiversity. Most tropical African countries lack long‐term climate data, so climate impacts on biodiversity cannot be assessed.

Geographic risks to functional groups of mammals and birds from habitat loss in Mexico
Conservation Biology, EarlyView.Abstract There is a need to quantify the impact of habitat loss due to anthropogenic factors on different aspects of biodiversity, such as functional trait diversity represented by functional groups (FGs). We developed a metric to assess the weighted risk of loss of habitat for 33 FGs of mammals and 36 FGs of birds in Mexico based on potential ...

Conservation Biology, EarlyView.Abstract Knowledge of species distributions is essential for informing policies on nature conservation and restoration. However, updating them on a regular basis and doing so in a harmonized manner at the international level is difficult. The European Bird Census Council integrated national monitoring data covering 5 years to update farmland bird ...

The Application of VaR Method Based on the MS-GARCH Model in Securities Asset Management Market [PDF]
, 2016 近几年来，我国券商资产管理业务取得了突飞猛进的发展，然而相应的风险管理学术研究较少。为了研究券商资管市场的风险管理VaR方法，本文选取股票型券商理财指数作为数据处理对象，假定模型的扰动项分别服从正态分布、t分布、广义误差分布、偏t分布、偏广义误差分布，采用单一状态GARCH族模型（GARCH模型、EGARCH模型、GJR-GARCH模型、APARCH模型）对数据进行建模。之后，文章在GARCH模型中引入马尔可夫状态转换过程，构建MS-GARCH模型 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Sodium metal batteries hold significant promise for large‐scale energy storage due to the high theoretical capacity and abundant sodium sources, yet sodium‐metal anodes are hindered by dendrite propagation, unstable solid electrolyte interphase, and poor cycling efficiency arising from uneven Na deposition and volume changes.

Dianci bileiqi, 1982 六、二维正态分布试验数据表明,在一定条件下,可以接受避雷器的放电电压u及预放电时间t服从二维正态分布的假设,则在确定了有关的分布参数后,就不难决定一定置信概率条件下,u、t的置信范围。由此即可使避雷器的所谓“最大”、“最小”放电电压,伏秒特性的上下包线等等有了确切的含义。

Jellyfish blooms restructure plankton dynamics and trophic linkages in coastal waters
Functional Ecology, Volume 40, Issue 5, Page 1443-1460, May 2026.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.

Attainment Pairing Effects on Cognitive Conflict in Technology‐enhanced EFL Cooperative Tasks
International Journal of Applied Linguistics, Volume 36, Issue 2, Page 1594-1605, May 2026.ABSTRACT This study examines how attainment pairing (high‐high versus high‐low versus low‐low attainment) impacts English as a Foreign Language (EFL) learner engagement during technology‐enhanced cooperative writing tasks. Seventy‐eight Chinese university learners formed 39 dyads (13 pairs per group) via Tencent Meeting.
