Rare Metals, EarlyView.ABSTRACT With the continuous advancement of materials science and technology, the rare metal gallium has increasingly emerged as a promising alternative to the toxic metal mercury. Although existing research has predominantly focused on the high electrical conductivity and excellent deformability of liquid metal (LM), its intrinsic fluidic property ...

Meiofauna Communities in Artificial Mangrove Wetland inTong’an Bay [PDF]
, 2015 红树林是热带亚热带海岸潮间带受周期性潮水浸淹，以红树植物为主体的常绿灌木或乔木组成的木本生物群落，是连接陆地和海洋的特殊森林。我国对红树林湿地的植物研究较多，对底栖动物研究较少；对红树林湿地大型底栖动物研究较多，对小型和微型底栖动物研究较少，特别是对人工红树林湿地小型底栖动物的研究更少。 本研究于2014年2月、5月、8月和11月，在同安湾的下潭尾和白兔山人工红树林湿地进行了4个季度小型底栖动物定量取样，系统的研究了小型底栖动物的类群组成、丰度、生物量和多样性等，并分析了自由生活海洋线虫的种类组成、丰度、

World Water Policy, Volume 12, Issue 1, February 2026.ABSTRACT Water security in tropical regions faces escalating pressures from climate change, land‐use shifts, and population growth. We conducted a bibliometric review of 1146 peer‐reviewed articles (1964–2023) on tropical water security. Latent Dirichlet Allocation identified 13 thematic topics and their evolution. Publications rose sharply after 2012,

, 2012 在阶段性降温条件下,研究了三种常用湿地植物黄鸢尾(Iris pseudacorus L.)、花菖蒲(Iris ensata Thunb.)及水芹(Oenabthe javanica)叶片抗寒性相关生理指标(可溶性蛋白质含量、可溶性糖含量、游离脯氨酸含量、丙二醛含量、超氧化物歧化酶活性、过氧化物酶活性、过氧化氢酶活性以及细胞质膜相对透性)的变化。结果表明,冷锻炼使湿地植物通过对抗氧化酶活性及渗透性的调节来提高其机体的抗寒性。低温条件下,黄鸢尾的抗氧化酶活性显著增加,5℃时SOD活性是初始值的5.77倍 ...

野生动物学报, 2005 中国是湿地大国,湿地面积居亚洲第一位,世界第四位,湿地总面积约为6594万公顷。截止到2000年,建立湿地保护区289处。湿地是地球上三大生态系统之一,与森林和海洋相比,湿地生态系统更加脆弱,与人类的发展关系更为紧密,其功能和价值的社会化程度体现得更为充分。由于湿地的概念提出较晚,湿地类型保护区的管理工作起步较迟,我国大部分湿地保护区的管理均相对落后,社会化程度普遍较低。本文力求分析湿地、湿地资源和湿地保护区的社会属性,从湿地保护区主体和客体的特点和问题入手 ...

Conservation Biology, Volume 39, Issue 6, December 2025.Abstract Identifying refugia from emerging threats is vital to ensure the persistence of rare and threatened species, but modeling habitat distribution for these species is challenging and the role of people in refuge management is rarely considered. Myrtle rust is an emerging infectious disease that represents a grave threat to the rare wetland tree ...

Bright spots for advancing ecological understanding and conservation decision‐making
Conservation Biology, Volume 39, Issue 6, December 2025.Abstract A lot can be learned by studying bright spots—defined as unexpected positive outcomes. In fields like public health, education, and oncology, identifying factors behind bright spots reveals previously unknown drivers of success that can be replicated elsewhere.

野生动物学报, 1997 松嫩平原中西部因长期地质下沉，湖泡星罗棋布，分布有大面积湿地。初步统计湿地面积约６０余万ｈｍ２，是水禽重要栖息繁殖地，也是东亚水禽南北迁徙主干线上的重要停歇地。现有扎龙、向海和莫莫格三个国家级湿地自然保护区。该平原主要有芦苇湿地、苔草湿地、浅水水生植物湿地和碱蓬盐沼。有鸟类２６０种，其中水禽８１种，水禽数量受湿地变化的影响。
