Symbiotic Germination Technique of an Endangered Epiphytic Orchid Dendrobium sinominutiflorum: A Promising Conservation Application 濒危附生兰科植物勐海石斛 (Dendrobium sinominutiflorum) 的共生萌发技术:一种具有应用前景的保护策略

open access: yesIntegrative Conservation, EarlyView.
We developed an effective ex‐situ conservation approach for an endangered orchid species, Dendrobium sinominutiflorum. A compatible fungal strain Tulasnella sp. was obtained by using in‐situ seed baiting technique. The Symbiotic germination with Tulasnella sp. significantly promotes seed germination and seedling growth.

Burrow‐Based Monitoring of Chinese Pangolin (Manis pentadactyla) Reveals Importance of Core Natural Habitat in Hong Kong 中華穿山甲 (Manis pentadactyla)洞穴監測揭示香港內陸郊野地帶的重要性

open access: yesIntegrative Conservation, EarlyView.
Relatively little is known about the distribution or habitat requirements of Hong Kong's population of the Chinese pangolin. Between 2018 and 2021 we searched for pangolin burrows and deployed camera traps on the burrows. We then analyzed habitat suitability at multiple scales to determine the factors that are key in driving pangolin distributions in ...

Evolution and Phylogenetics of the Javan Hawk‐Eagle Nisaetus bartelsi (Stresemann, 1924) Using Mitochondrial Data 爪哇鹰雕 Nisaetus bartelsi (Stresemann, 1924) 基于线粒体数据的演化与系统发育研究

open access: yesIntegrative Conservation, EarlyView.
This study reconstructs the phylogeny of the Javan Hawk‐Eagle (Nisaetus bartelsi) within the subfamily Aquilinae using Maximum Likelihood and Bayesian Inference algorithms on a blood sample and GenBank data. The analysis reveals that the sampled genus Nisaetus forms a monophyletic group. Furthermore, N. bartelsi occupies a sister‐taxon of N.

Synthesis and characterization of an acrylonitrile-based copolymer containing carbohydrate Moieties(一种含糖丙烯腈共聚物的合成与表征)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2009
以五乙酰基葡萄糖和甲基丙烯酸-2-羟基乙酯(HEMA)为原料,以路易斯酸—三氟化硼乙醚络合物(BF3 •Et2O)为催化剂,方便地合成了一种含糖单体—甲基丙烯酸-2-(2',3',4' ,6'-四-O乙酰基-β-D-吡喃葡萄糖氧)乙酯(AcGEMA).该单体与丙烯腈(AN)经自由基溶液聚合的方法进行了共聚.单体和共聚物结构分别经红外、核磁证实.以水接触角测定脱乙酰保护后的含糖共聚物膜表面,结果表明脱乙酰化可显著提高膜表面亲水性.因此,用共聚法对聚丙烯腈膜改性,使其表面引入糖基,可以改善聚合物膜的亲水性 ...

Threats to the World's Bears and Efforts to Conserve Them: Perspectives and Actions of IUCN Bear Specialist Group Members 世界熊类面临的威胁及其保护努力:IUCN熊类专家组成员的观点与行动

open access: yesIntegrative Conservation, EarlyView.
A survey of IUCN Bear Specialist Group (BSG) members revealed that habitat loss, degradation and fragmentation is the greatest threat to each of the 7 species of terrestrial bears. Poaching and human–bear conflicts are also high threats for some of these species.

Studies on the critical period of floral differentiation and changes of endogenous hormone contents in the decapitated seedlings of cucumber(黄瓜去顶苗花分化临界期的确定及内源激素的动态变化)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2004
通过在诱花和诱芽培养基之间转换培养,发现黄瓜去顶苗花分化临界期是培养后的第5至6天(即去顶后的3至4天).对花芽分化初期子叶节中内源激素质量分数的测定表明,IAA质量分数在花芽分化初期处于较低水平,ZT质量分数呈下降趋势,GA3质量分数则出现升-降-升的波动状态.ZT/IAA、GA3/IAA比值的变化趋势相似,0至2天上升,2至3天下降,3至4天再上升.根据实验结果,联系黄瓜去顶苗成花的形态变化过程,对激素质量分数变化与花芽分化之间的关系进行了讨论.

Intangible drivers of tolerance shape human–elephant coexistence in Southwest China

open access: yesPeople and Nature, EarlyView.
Abstract Southwest China is home to a small but rapidly expanding population of Asian elephants (Elephas maximus), whose growth has intensified conflicts with people living in shared landscapes. These conflicts result in substantial economic losses and occasional human casualties. This coexistence paradox—where conservation success leads to significant
