生物地理学

By separation and combination analyses of nuclear rDNA ITS and the cpDNA (matK gene, rpl16 intron and atpB-rbcL spacer) sequences, the interspecific relationships were discussed, and the classification review and biogeographic analysis were done for all species bearing raceme or spike of one to many umbels with prophylla at base.

运用nrDNA ITS及cpDNA(matK、rpl16、atpB-rbcL)序列的单独和联合分析探讨了这些类群的种间关系，并对世界菝葜属中具有一至多个伞形花序排列成圆锥花序或穗状花序、花序梗上有关节的所有种进行了分类学研究及生物地理学研究。

The census encompasses an alphabet soup of projects, including ChEss (Biogeography of Deep-Water Chemosynthetic Ecosystems) and TOPP.

普查报告中含有一系列有关各项目的字母缩写体，包括ChEss（生物地理学之深水化能合成生态系统）和TOPP。

Squamata are the most largest taxon of reptiles which distributed all over the world, and they are widely used in ecological, biogeogrophical and evolutionary studies.

有鳞目是现存爬行动物中种类最多的一类，分布遍及世界各地，形态多样，其一直被广泛应用于生态学、生物地理学及探讨物种进化的研究。

The book covers both plants and animals, and deals with all relevant areas of research, including biogeography, field work, systematics, theory, and genetic and molecular studies, with special emphasis to topics,including sympatric speciation, reinforcement, the role of hybridization in speciation, the search for genes causing reproductive isolation, and mounting evidence for the role of natural and sexual selection in the origin of species.

该书内容覆盖植物和动物，并且涉及所有相关的研究领域，包括生物地理学，野外工作，系统分类学，理论，和遗传和分子研究，特别强调了包括同区域物种形成，增强，杂交在物种形成中的作用，寻找导致生殖隔离的基因，寻找自然和性别选择在物种起源中作用的证据。

There are some reports about G. maculatum mainly focus on its taxology, biogeography and the phylogeny of Glyptosternoid fishes. No reports on biochemical genetics of G. maculatum or other Glyptosternoid fishes were found.

关于黑斑原鮡的研究，多集中于分类、生物地理学及鰋鮡鱼类系统演化、进化等方面，目前为止，尚无黑斑原鮡群体或鰋鮡鱼类生化遗传方面的研究报道。

But the resources competition theories in earlier period have mainly come from chemostat model. Up to 90\'s in 20 centuries, a large numbers of species inhabit patchy environments due to fragmentation of landscape resulting from unreasonable economic activities by man.

到了20世纪90年代，由于人类不合理的经济活动造成景观格局的破碎化，使得大量的物种栖息于斑块状的环境中，于是生态学的理论中出现了岛屿生物地理学和集合种群的概念。

Palaeogeography of China comes from stratigraphy, historical geology, tectonics, palaeontology, sedimentary petrology, natural geography, Quaternary geology, archaeology, human historical geography, etc.. Thus branch disciplines such as stratigraphic palaeogeography, tectonic palaeogeography, palaeontological palaeogeography, lithofacies palaeogeography, natural geographic palaeogeography, Quaternary palaeogeography, human historical palaeogeography, etc. are originated and developed.

我国古地理学来源於地理学、地史学、大地构造学、古生物学、沈积岩石学、自然地理学、第四纪地质学、考古学、人类历史地理学等，因此就相应地产生和形成了地层古地理学、构造古地理学、生物古地理学、岩相古地理学、自然地理古地理学、第四纪古地理学、人类历史古地理学等分支学科。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
