Rejuvenation of dinosaurian origin of birds and its theoretical difficulties
In 1986, Prof. Jacques Gauthier from Yale University first applied cladistic systimaties to the analysis of the relationships between birds and other species in archosauria, a basal reptilian group that includes dinosaurs, pterosaurs, crocodilias and some other extinct reptilians. His analysis further confirmed that birds might have originated from a branch of small theropods close to Deinonychosauria. Encouraged by this work, the paleontological community cast intense attention to birds＇ dinosaurian origin theory, 相似文献

竞争情报分析的二象性研究 总被引：1，自引：0，他引：1
本文通过引入波粒二象性理论,确定了竞争情报的二象性特性,竞争情报的类波现象和类粒子现象在实际中表现为竞争情报能量或价值的聚集和能量或价值的分布。在此基础上,本文探讨了竞争情报分析的二象性,即分析性与解释性,讨论了分析性与解释性的作用机理以及活动行为。Abstract： By introducing the theory of wave-particle duality,the duality property of competitive intelligence is determined. The wave phenomenon and particle phenomenon of competitive intelligence are represented as the aggregation of the energy or the value of competitive intelligence and the distribution of the energy or the value of competitive intelligence in practice. On this basis, this paper discusses the duality of competitive intelligence analysis, namely,the analytical and interpretative characters. The paper also discusses the functional mechanism and operational behavior of the analytical and interpretative characters. 相似文献

鳞毛蕨属的生物系统学研究 总被引：1，自引：0，他引：1
Jermy A. C. 《中国科学院研究生院学报》1980,18(1):37-44
At the outset the paper begins with a brief discussion of the geographical origin of the
genus Dryopteris. With the cytological data so far available the author presumed that the No-
rthern Hemisphere and possibly Eurasia is the geographical origin of the genus and that the
Eastern Himalayas, China and Japan is the centre of speciation of the genus, and thence has
spread to other continents along several routes. He is also of the opinion that the genus tends
to evolve the highest grade of polyploidy where it has existed longest. On the other hand, he
pointed out that the production of polyploids may occur most frequently in response to pressures
which a group meets in the course of its migration in space and time, with the majority of
diploids persisting as relics close to the original centre of diversification.
He then described the progress of the biosystematics of the European and North American
Dryopteris, which has been undertaken through a close cooperation among botanists, cytologists
and phytochemists of different nations. This team is also looking forward to a cooperation with
the Chinese botanists in the study of East Asian species of Dryopteris, so that the relationships
of Chinese species and those of other floras can be understood.
The term biosystematics had been invented to mean experimental studies of breeding sy-
stems of the species concerned in order to ellucidate their evolutionary relationships. It stems
from the early researches of Professor Irene Manton whose classical book “Problems of Cytology
and Evolution in the Pteridophyta” (1950) laid the foundation of Biosystematics. Manton was
also the first to introduce the acetocarmine squash method for staining chromosomes in the
spore-mother-cells at meiosis.
The lecture was illustrated with diagrams showing in detail the pairing behaviour of the
chromosomes at the metaphase in meiosis and the formation of the polyploidies of different
levels.
Besides cytological approach two other techniques have been also applied to the systematic
studies of Dryopteris. The first is the comparison of sporoderms using the scaning electron
microscope, revealing different ornamentations on the pericine. The second is the study of plant
chemistry, in particular, that of the phloroglucinoles by thinlayer chromatography.
The remaining far greater part of the paper is devoted to analysing cytologically the Eu-
ropean and North American species of Dryopteris in three groups, showing the lines of experi-mental work that has resulted in the understanding of their evolutional relationships. 相似文献
