Plant invasion in mountain ecosystems reduces soil micro‐food web complexity at higher elevations
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Anthropogenic activities have accelerated plant invasions in mountain ecosystems, impacting the structure and functions of native plant communities. Changes in above‐ground vegetation can drive shifts in below‐ground biota, yet the effects of plant invasions on soil ...

Guangxi Zhiwu水韭属是一类具有异形孢子的古老石松类植物，全属物种均被列入国家重点保护野生植物。该文报道了在浙江省长兴县新发现的一个四倍体水韭属居群。基于形态学、孢粉学和细胞学证据，将该物种命名为长兴水韭（Isoëtes changxingensis），并详细描述了其形态特征。长兴水韭与保东水韭（I. baodongii）在植株形态及孢子纹饰方面都较为相似，不同之处在于其染色体为44条，大孢子极面直径为317~411 μm（平均为360 μm）（vs.染色体22条，大孢子极面直径为390~510 μm，平均为450 ...

International Journal of Urban and Regional Research, EarlyView.Abstract From desert ski resorts to subtropical Winter Games, there is a global proliferation of ‘mission‐impossible’ mega‐projects. The prevailing frameworks of city branding and urban entrepreneurism fail to explain the political logics behind these seemingly irrational projects.

Potential harm of coastal sedimentary nutrient in inducing red tide(沿海沉积营养物质对引发赤潮的潜在影响)
Zhejiang Daxue xuebao. Lixue ban, 2004 从生物地球化学的角度阐述了引发赤潮的营养和环境控制因素，并在分析了赤潮藻的限制性营养元素（磷、氮、硅）和微量元素（铁、锰）环境地球化学行为的基础上，提出了沿海沉积营养元素的释放与赤潮之间的相关关系模式，同时指出了中国沿海近代沉积物中营养物的积累趋势及其对引发赤潮的潜在危害，这不仅为揭示赤潮发生机理开辟了新的研究方向，而且也为有效地防治赤潮危害提供了科学依据.

Journal of Analytical Psychology, EarlyView.Abstract This article outlines an integrative, trauma‐oriented, polyvagal‐informed framework for psychodynamic psychotherapy. In this approach, patients are inherently motivated to overcome entrenched, repetitive patterns, seeking to restore a sense of safety that was lost during developmental phases.

Comprehensive framework for assessing and optimizing existing research networks
Conservation Biology, EarlyView.Abstract Conservation, monitoring, and research networks, or collections of ecological research sites unified under a common mission of data collection or a research mission, are essential infrastructure for understanding large landscapes. However, most networks developed opportunistically over decades rather than through systematic design, creating ...

Species composition of small mammals in Jinhua City(金华城区小型兽类种类组成)
Zhejiang Daxue xuebao. Lixue ban, 2003 1997年1月至1999年12月,选择金华城区的居民区、宾馆、粮库和工厂等4种生境5个调查点以夹夜法对常规灭鼠中小型兽类的种类组成进行了分析和研究.结果表明:金华城区共有臭鼩鼱(Suncus murinus)、褐家鼠(Rattus norvegicus)、黄胸鼠(Rattus flavipectus)、小家鼠(Mus musculus)和黑线姬鼠(Apodemus agrarms)等5种小型兽类;种类组成呈现以褐家鼠为主,臭鼩鼱和黑线姬鼠为次,黄胸鼠和小家鼠较少的格局 ...

Advancing conservation breeding programs for marine invertebrates
Conservation Biology, EarlyView.Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.

Jingshui jishu【目的】目前，我国已经形成了深度脱水-填埋、好氧发酵-土地利用、厌氧消化-土地利用、干化焚烧-建材利用这4条主流的市政污泥处理处置工艺路线，每种工艺路线都有各自的优缺点和适用条件，但每种路线的碳排放水平尚不明确，致使碳排放难以作为工艺比选测算指标落地应用。【方法】根据联合国政府间气候变化专门委员会指南，采用排放因子法，在确定核算边界后，全面核算了污泥从污水处理厂外运直至最终消纳的全流程碳排放量，包括处理处置过程中因甲烷(CH 4)和一氧化二氮(N 2O ...
