Informing spatial conservation prioritization with species’ traits
Abstract New Guinea, the most botanically diverse island on the planet, is the location for one of the boldest conservation initiatives. The Manokwari Declaration aims to achieve 70% conservation designation for the Bird's Head Peninsula. This is 40% higher than the 2022 Global Biodiversity Framework target.

Study on restoration of benthic macrofaunal community in Xiatanwei artificial mangrove wetlands, Tong’an Bay [PDF]
红树林生态系统处于海洋与陆地的动态交界面,是我国三大海岸带生态系统之一。底栖动物(包括大型、小型和微型底栖动物)是红树林生态系统的重要组成部分,同时也是该生态系统内物质循环、能量流动中积极的消费者和转移者。关于同安湾潮间带、潮下带和红树林湿地大型底栖动物群落生态的研究已有报道,但关于同安湾人工红树林湿地大型底栖动物群落恢复、演替和功能群方面的研究稀少,且关于红树林群落边缘大型底栖动物的群落效应的研究未见报道。 本研究选取同安湾下潭尾人工红树林湿地作为研究区域 ...

生态治理技术适宜性评价影响因素及概念模型——以沙漠化治理技术为例 [PDF]
生态系统退化已是全球的主要环境问题,旨在恢复和重建生态系统的生态治理技术受到重视。在众多直接、间接的技术中,如何遴选最适宜的技术,目前仍缺乏系统、科学、完善的评价方法。根据对其他领域中有关技术评价理论、方法、要素等的梳理,以沙漠化治理技术涉及的多个影响因素为例,首次提出一般性生态治理技术适宜性评价概念模型——"双圈十二维"模型,包括两类十二个维度:(1)内生因素(内圈):限制性、独立性、经济性、可操作性;(2)外部因素(外圈):目标、地域、时效、政治政策制度 ...

ABSTRACT A major challenge in fabricating eutectic NiTiNb alloys is the incomplete melting of Nb due to its much higher melting point than the NiTi matrix. In this work, a novel electron‐beam freeform additive manufacturing strategy is developed to eliminate unmelted Nb particles and achieve a fully eutectic structure through independent dual‐wire ...

Quantifying Payment Criteria of Hydropower Development for Watershed Ecosystem Services ---- Case Study of Jiulong River Watershed [PDF]
水电资源传统上被认为是完全绿色清洁的能源,但随着认识的全面和深入,水电资源开发与流域生态环境保护的冲突日益受到关注;流域生态补偿机制作为应对流域性环境问题的一种制度安排,正成为研究和实践的热点;但是将生态补偿应用于水电资源开发的决策和管理过程的研究还不多见。本文以水电资源开发的生态补偿为研究对象,具有重大的现实意义和应用价值。 补偿标准的确定是生态补偿机制的关键问题,也是学界争议最大的问题之一。本文围绕“水电资源开发生态补偿标准的量化方法”这一主题,开展了“理论—方法—实践”的深入研究 ...

Effects of landscape fragmentation on floodplain fishes as revealed by species–habitat networks
Abstract How species interact with habitat patches is influenced primarily by habitat configuration (e.g., connectivity) and species’ functional traits. As levels of fragmentation increase, identifying the intricate connections between these components is crucial for biodiversity conservation.

Research on Management Problem and Countermeasures of China Marine Protected Areas——In Binzhou Chenier Island and Wetland National Nature Reserve as an Example [PDF]
海洋蕴藏的巨量资源是人类未来发展的物质基础,合理开发与保护海洋资源是人类实现永续发展的必然选择。面对海洋资源日益枯竭,海洋环境压力日益增大的现状,海洋保护区的建设和管理已经成为全球性的热点问题。然而,由于我国海洋保护区建设起步时间晚,海洋资源环境压力巨大等原因,导致海洋保护区管理过程中出现诸多问题,海洋保护区的建设和管理并未达到预期的保护效果。本文通过研究国内外海洋保护区的发展历程、概念、分类和作用,以滨州贝壳堤岛与湿地国家级自然保护区(以下简称:滨州贝壳堤岛与湿地保护区 ...

ABSTRACT Metal oxide semiconductor‐supported noble metal nanoparticles are common sensing materials for gas sensors. However, the large size and their tendency to migrate at high temperatures often lead to inferior sensing sensitivity and stability. Herein, a salt‐assistant strategy is developed to prepare fully‐exposed Ir clusters on SnO2 nanorods ...
