Neutral interactions among non‐native plants are common

open access: yesNew Phytologist, Volume 252, Issue 1, Page 292-309, October 2026.
Global distribution of studies and overall effect of co‐invasion for all metrics of non‐native plant performance combined. Summary Globalization has accelerated the establishment of non‐native plant species, increasing the prevalence of multispecies co‐invasions; yet interactions among co‐invaders remain poorly understood.

Green Hydrogen in Brazilian Media: Dominant Narratives and Missing Dimensions of the Energy Trilemma

open access: yesPolitics &Policy, Volume 54, Issue 5, October 2026.
ABSTRACT Media discourses help shape the visibility and legitimacy of energy transition pathways in the public sphere. This study examines how Brazilian mainstream newspapers framed green hydrogen and assesses the alignment of these narratives with the energy trilemma: energy security, environmental sustainability, and social accessibility. We analyzed

鱼类特异的基因组复制

open access: yes, 2006
辐鳍鱼类是脊椎动物中种类最多、分布最广的类群,其基因组大小不等。过去的观点认为,在脊椎动物进化历程中曾发生了两次基因组复制。近期的系统基因组学研究资料进一步提出,在大约350百万年,辐鳍鱼还发生了第三次基因组复制,即鱼类特异的基因组复制(fish-specificgenomeduplication,FSGD),且发生的时间正处在“物种极度丰富”的硬骨鱼谱系(真骨总目)和“物种贫乏”的谱系(辐鳍鱼纲基部的类群)出现分歧的时间点 ...

齿肋赤藓乙醛脱氢酶基因ALDH21的克隆与表达分析

open access: yes, 2010
本文采用RT-PCR方法,从齿肋赤藓(Syntrichia caninervis)总RNA中获得ALDH21基因cDNA序列,连接到pMD19-T载体上并转化E.coli DH5α,阳性克隆经PCR鉴定后测序,将测序结果与GenBank中山墙藓(Tortula ruralis)和小立碗藓(Physcomitrella patens)相关基因序列进行同源性比对。结果表明,实验成功克隆了S.caninervis的ALDH21基因的cDNA序列(GenBank登录号:GQ245973),为一个完整的ORF ...

基因改造食品之標示的相關法律問題探討

open access: yes, 2009
本文是以基因改造食品之標示的相關法律問題為思考的對象,首先釐清通稱之「基因改造食品」概念下實含有數種表現型態,其次,藉由歐盟就基因改造食品所為之完整的標示規範為比較法制的借鏡,以求掌握標示規範的相關內涵。緊接著則進一步掌握基改食品強制標示與任意標示的意義與法律性質,以確定行政機關是否有權逕行規定標示之要求。隨後,則應分析檢討食品衛生管理法的相關規範內容,並指出該法無法成為基改食品要求強制標示之法律依據。本文最終目的在指出我國現階段基因科技領域欠缺專門之法律規範的情況下 ...
