     Qiongzhou strait occurred from early Quaternary, so the endemic species of ferns in Taiwan and Hainan island are more less that of seed plants (Taiwan has 801 endemic species of seed plants, Hainan has 501 endemic species of seed plants), the cause can be attributed to their greater dispersibility, because many of the speciation barriers which play a considerable role in angiosperms are absent in ferns;

The possible effect of biologic properties of species on mass extinction has been discussed in terms of population ecology, rate of evolutionary turnover and rates of speciation and extinction. Data from fusulinids,ammonoids corals and brachiopods indicate that the "anti-catastrophe ability" is directly proportional to their areas of geographic distribution, and correlated reversely with their rates of evolution. The fates of organisms which are in their different evolutionary stages may differ from each other...

本文从居群生态学的角度出发,结合生物演化的更替速率、成种速率及灭绝速率讨论了物种的生物学特征在生物绝灭事件中的可能影响。监管蜓类、菊石、珊瑚及腕足动物的资料表明,生物的“抗灾变能力和生物的地理分布范围成正比,和生物的演化速率成反比。同时,生物在绝灭事件中的命运也和它们当时所处的演化阶段有密切的关系。

Among palaeontologists almost every one has recognized the vexation of species problem in palaeontology. This has been usually attributed to the presence of the time dimension which makes it impossible to apply the commonly accepted biological species definition and at the same time recognize species as discrete, nonarbitrary entities (Raup and Stanley, 1978, p. 109). But this problem is more theoretical than real. In fact, palaeontologists have seldom met evolutionary continua in the fossil record which make...

Among palaeontologists almost every one has recognized the vexation of species problem in palaeontology. This has been usually attributed to the presence of the time dimension which makes it impossible to apply the commonly accepted biological species definition and at the same time recognize species as discrete, nonarbitrary entities (Raup and Stanley, 1978, p. 109). But this problem is more theoretical than real. In fact, palaeontologists have seldom met evolutionary continua in the fossil record which make them difficult in delimiting species. Even when evolutionary continua do occur, subdivision need not be entirely arbitrary (Imbrie, 1956). We believe that species should be objective entities with difinite temporal and spatial distributions. "A species is a single lineage linked up with other lineages by speciation events which is a reproductive and genetic community composed of ancestral-descendant populations with its own evolutionary position and historical fate, and which maintains its distinctive identity from other such lineages and occupies or occupied a specific niche in nature" (Fang, 1990, p. 45). Here speciation is defined as the evolutionary process of species formation including phyletic speciation (= phyletic transition, Raup and Stanley, 1978)——the appearance of a new species by the gradual evolution of an entire lineage. The speciation event, which is not all equal to the branching points in this paper, occurs when the genetic homesotasis of a species is transformed into another.

目前在我国古生物学研究中存在着许多有关物种判别的问题。在相当程度上这是与居群概念的贫乏和传统的林奈式类型-形态学研究方法的影响分不开的。广泛存在于物种间的形态间断为识别物种带来了方便,但它与生殖隔离并不完全吻合。若只考虑形态特征,所判定的化石种大多只相当于表型单元。本文探讨如何将形态标准与居群、群落-生态和时空等项标准相结合来区分物种与表型单元。以上这些标准分别反映了物种的生物学特性的不同方面,而生殖一遗传标准是将它们有机地联系在一起的共同基础。古生物学必须站在理性的高度上俯瞰生命发展过程中的物种,从现代生物学的知识库中汲取养料。化石种研究现状的改观尚有待于我们付出艰巨的努力。通过这种努力将使古生物学进入一个新的、更严格的科学发展阶段。

保护生物多样性在林木育种中必须予以重视。传统的林木育种主要考虑遗传增益。长期育种则以维持育种群体的变异性为主要目的。具有丰富生物多样性的天然森林群体是长期育种的基础。长期育种研究应以物种生物学、群体遗传学和居群生态学等为理论基础。主要研究森林群体的性质及群体的动态变化规律。传统林木育种的研究方向、研究内容及林木育种学的教学内容等都应予以适当的调整和补充。
