二十世纪末兴起的分子生态学作为一门前沿学科,被众多高校列入课程体系。其学科领域囊括了分子生物学、生态学、行为生物学、进化及遗传学的多个主体,学科交叉广泛深入,课程的信息量也十分巨大,因此在本科教学过程中不仅对学生更对教师提出了更高的要求,本文针对课程教学过程中出现的问题,结合教学实践,初步探索了该学科的特点及其教学模式。 相似文献

流域生态学——生态学研究的一个新领域 总被引:31,自引:3,他引:31
由于人类不合理开发和利用自然资源,造成了流域生态环境的重大破坏,为了合理开放流域资源和保护生态环境,非常有必要开展流域生态学的研究。文中系统阐述了流域生态学的重要意义、主要研究内容和方法。流域生态学属于宏观生态学的研究领域,主要借助于宏观生态学的研究方法。流域生态学与目前生态学最关注的“全球变化、生物多样性和可持续发展”3个研究问题紧密结合在一起,极具研究价值,建议开展广泛深入的研究。 相似文献

Ecological science is often organised as a hierarchical series of entities: genes, individuals, populations, species, communities, ecosystems and biosphere. Here, I consider an alternative process‐based approach to ecology, and analyse the nature of the fundamental processes in ecology. These fundamental processes are discussed in the context of the following question:‘for any planet with carbon‐based life, which persists over geological time scales, what are the minimum set of ecological processes that must be present?‘I suggest that the following processes would be present on any such planet: energy flow, multiple guilds, ecological tradeo ffs leading to within‐guild biodiversity, ecological hypercycles, merging of organismal and ecological physiology, carbon sequestration and possibly photosynthesis. Nutrient cycling is described as an emergent property of these fundamental processes. I discuss reasons why a biosphere based on a single species with no nutrient cycling is very unlikely to exist. I also describe the concept of ‘Gaian effect’. This suggests that some processes will always tend to extend the lifespan of a biosphere in which they develop (positive Gaian effect) while others could either increase or decrease (negative Gaian effect) such a lifespan. These ideas are discussed in the context of astrobiology, ecosystem services, conservation biology and Gaia theory. 相似文献

Abstract. Scientific progress in plant ecology is at risk of being obscured by increasing ignorance of major works in the field. The driving force seems to be the twin seductions of novelty and crowd psychology. I illustrate this tendency with three examples from plant community ecology that span the past thirty years of ecological research. I offer, as one solution, the concept of a canon: a short list of essential books that we assume all students and co‐workers have read, a short list that summarizes the wisdom of the discipline. A canon can be likened to DNA, be it in music, art, or science, as it carries forward through time the key ideas that have worked in the past. Without a canon, there is no memory of past achievement, no context for appreciating current work, and no way of judging the quality of newer productions. I suggest 20 essential books (the short canon), and 22 complementary readings, for a total of 42 books needed in any young professional's library on plant ecology. 相似文献

我国高校生态学专业建设与人才培养方向探讨 总被引:2,自引:0,他引:2
对我国生态学专业建设与人才培养存在的问题进行了分析,认为当前存在几方面问题:生态学科和生态学新专业快速发展与师资力量相对薄弱之间的矛盾、课程设置和教学内容的“泛与专、深与浅”之间的矛盾、生态学教学的“软”与生态环境建设的“硬”之间的矛盾,以及社会对生态学人才的现实需求与实际供给之间的矛盾.提出了相关的改革思路与对策:制定生态学专业相关的发展建设规划,适度调整招生规模;实现教学内容与教学方式“从课堂到田间”、“从软到硬”的转变;发展与推行参与性、互动式、研究型和创新型等多元化教学方法;加大生态学专业本科教学质量工程以及教学资源库建设力度,实现资源共享;建立生态学“T”型人才培养模式.最后,针对生态学毕业生的就业问题,提出了一系列以就业为导向的生态学专业人才培养方向. 相似文献

Physiology may play an important, if not essential role, in a liberal arts education because it provides a context for integrating information and concepts from diverse biological and extra-biological disciplines. Instructors of physiology may aid in fulfilling this role by clarifying the core concepts that physiological details exemplify. As an example, presented here are the core principles that are the basis for an undergraduate physiology course taught at the University of Chicago. The first of these is: Evolution has resulted in organisms comprising mechanisms for maintenance, growth, and reproduction, despite perturbations of the internal and external environment. Such principles necessitate a coupling of physiology to diverse disciplines (i.e., "sciomics") and provide a basis for integrating discoveries in other disciplines. 相似文献
