Rare Metals, EarlyView.ABSTRACT The growing concern over human health issues, driven by increasingly severe electromagnetic pollution from 5G communication, has made the urgent development of high‐performance electromagnetic wave (EMW) absorbing materials. Although carbide‐based materials are promising because of their conductive and polarization losses, existing single ...

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract The nested subset pattern (nestedness) has been widely used to explain species distributions in island and fragmented systems. Mountain sky islands serve as critical natural laboratories for understanding the evolutionary consequences of geographic isolation and climate

Proteomic Response of Prorocentrum donghaiense to Phosphorus Depletion and Resupplement [PDF]
, 2015 磷(Phosphorus，P)是海洋浮游植物生长的限制因子，影响海洋初级生产力。东海原甲藻（Prorocentrumdonghaiense，P.donghaiense）是引起我国近海有害藻华的主要甲藻。目前有关磷对甲藻生长影响的研究已有很多报道，但主要集中在生理生态层面，对甲藻在磷限制条件下及其补充响应的分子机理方面了解较少。 本论文以P.donghaiense为研究对象，运用基于质谱的定量蛋白质组学技术—串联质谱标记（Tandemmasstag，TMT），并结合相应的转录组数据，比较研究了P ...

Methods in Ecology and Evolution, EarlyView.Abstract DNA barcode‐based species identification has become pivotal in biodiversity research. Current barcoding‐based deep learning methods have advantages in species identification but exhibit significant limitations. By using COI barcoding alone, previous studies were unable to fully capture species identification features. Prior methods showed that

Transcriptome and Proteome Analysis During Larval Settlement and Metamorphosis in Fujian Oyster(Crassostrea angulata) [PDF]
, 2016 附着变态衔接浮游阶段与底栖阶段，是海洋无脊椎动物生活史的重要环节，附着变态过程涉及到复杂的生理过程和行为形态的改变，人们至今未能很好地阐释其中涉及到的分子机制。福建牡蛎（Crassostreaangulata）是我国南方主要的贝类养殖种之一，具有典型的附着变态过程。然而关于牡蛎附着变态过程的分子研究停留在个别基因的克隆和定量表达的研究，这并不能反映附着变态过程的多基因的调控网络。有大量的药理学研究表明肾上腺素能够诱导牡蛎幼体未经附着而直接变态，但是肾上腺素诱导的分子机制的研究至今空白。本研究采用转录组学、

Representation of obligate groundwater‐dwelling copepod diversity in European protected areas
Conservation Biology, EarlyView.Abstract Groundwaters sustain diverse surface ecosystems and are populated by metazoan species, mostly invertebrates, that provide fundamental ecological functions and are often of prominent conservation value due to narrow endemism and high phylogenetic rarity.

Detoxification and Antioxidant Defence of Marine Medaka(Ozyzias melastigma) Liver against Hexavalent Chromium Exposure [PDF]
, 2016 近年来，随着工业化进程的深入和沿海城市化的发展，工农业和城市生活污水的排入，导致近海海域铬污染问题日益严重，对海洋生物生存和人类健康造成了危害。海洋青鳉鱼(Oryziasmelastigma)因其对水质、环境变化敏感，被广泛应用于海洋污染物的毒理学研究中，是一种新兴的海洋生态毒理学模式生物。为探究海洋鱼类对六价铬暴露的抗氧化防御、解毒机制，本论文以海洋青鳉鱼成鱼肝脏、幼鱼为材料，进行了初步探讨。得到以下结果： （1）以3月龄海洋青鳉鱼成鱼进行Cr6+暴露试验，试验组Cr6+浓度设置为2.6lmg/L、5.

Conservation Biology, EarlyView.Abstract Despite the crucial role of human impacts on biodiversity loss, many assessments of this loss focus on single metrics, such as species richness, and overlook the multidimensional effects of human activities. Because of its importance to ecosystem functioning, we investigated the functional diversity of medium‐ and large‐sized mammal ...
