, 2021 生态系统是由生物群落及其生存环境共同组成的动态平衡体系,是生态学研究的基本单元。自20世纪30年代提出生态系统概念(Tansley,1935)以来,生态系统生态学逐渐成为生态学研究的核心方向之一,形成了完备的理论与方法体系。近年来,全球变化不断加剧,并已对生态系统的结构和过程产生了深远的影响。解析生态系统组成、结构及其动态,阐明其对生态系统功能和服务的影响,是认识生态系统如何响应全球变化的基础 ...

Off‐Task Talk to Manage Relationship Work During Student Group Work in Second Language Classrooms
International Journal of Applied Linguistics, EarlyView.ABSTRACT This paper presents a conversation analytic study on student relationship work in off‐task talk (OTT) during group work in foreign language classrooms. Often seen as disengagement from tasks, OTT's social and relational functions in student classroom group interaction and formation remain underexplored.

, 2011 物种分布与多度间的正相关格局非常普遍,但该格局的生态机制却一直不太明确。提出了很多假说来解释这种分布-多度关系,其中物种的生态幅和生态位(资源可利用性)机制的研究较多。为了验证物种的生态幅和生态位是否能解释物种的多度-分布格局,研究了黄河三角洲地区湿地植物分布、多度、生态位和生态幅间的关系,结果表明:该区物种分布与多度呈显著正相关,且均与生态幅显著正相关,物种分布与生态位显著负相关,但物种多度与生态位相关性不显著。这说明物种的分布越广,其多度越高,环境容忍度越大;而可利用资源更多的物种分布更广 ...

, 2017 藻类是海洋中重要的初级生产者,从热带到极地均有分布。在不同的生态环境中,藻类为了适应不同环境条件及环境变化,逐渐形成了不同的生态类型。本文对生态型的概念、研究方法进行归纳总结,提出大型藻类生态型的划分方法,即根据生态环境、生物学特征和遗传特征进行划分。着重分析了藻类生态型的研究现状、存在的问题,提出表型特征可以作为一个划分生态型的参考因素,但不能作为绝对的衡量标准。最后,作者通过分析黄海漂浮浒苔的环境特点、遗传差异和生物学特征,将漂浮浒苔视为一种漂浮生态型 ...

There Is Always a Bigger Fish. Determinants of Power Perceptions in Swiss Biodiversity Policy
Policy Studies Journal, EarlyView.ABSTRACT The Advocacy Coalition Framework (ACF) views power as crucial in policy processes, but the nature of coalition power, its determinants, and how to empirically measure it remain understudied. In this article, we use a mixed method approach and social network analysis to explore power relationships in the biodiversity policy subsystem in ...
