查询词典 genus and species

It is indicated that the 13 species of the genus Lycoris were divided into two groups, and five species of the genus including L.rosea ﹑ L.haywardii、L.straminea、L.sprengeri and L.radiata with monotype karyotypes (1-shaped) were clustered together respectively. The basic chromosome number was x=11. The others which have two-types karyotypes (I-shaped and V-shaped ) were clustered together respectively. They were L.houdyshe lii, L.albiflora, L.chinensis,L.longituba,L.anhuiensis,L.squmigera,L.caldwellii and L.aurea . The closest relationship was between L.rosea and L.haywardii.

结果表明：石蒜属13个种明显聚为两大类，即具有单型核型结构、染色体基数为x=11的5个物种：玫瑰石蒜 L.rosea 、红蓝石蒜 L.haywardii 、稻草石蒜 L.straminea 、换锦花 L.sprengeri 和石蒜 L.radiata 聚为一类；具有两型核型结构8个物种即江苏石蒜 L.houdyshelii 、乳白石蒜 L.albiflora 、中国石蒜 L.chinensis 、长筒石蒜 L.longituba 、安徽石蒜 L.anhuiensis 、夏水仙 L.squmigera 、短蕊石蒜 L.caldwellii 和忽地笑 L.aurea 聚为一类。

It is indicated that the involved species of this subfamily clustered into two clades: the first clade includes those of the genus Neptis, Phaedyma, Pantoporia and Lintinga; the second one includes those of the genus Parthenos, Moduza, Limenitis, Athyma, Lexias and Euthalia. The genus Limenitis is suggested to be monophyletic; and the genera Euthalia and Lexias proved to be sister to each other and form a monophyletic group. The genus Litinga appears to be more closely related to Neptini than to Limenitini.

基于Cytb基因的线蛱蝶亚科系统发育分析结果表明，所有线蛱蝶亚科聚为两大枝：第一枝包括环蛱蝶属、菲蛱蝶属、蟠蛱蝶属和缕蛱蝶属；第二枝包括丽蛱蝶属、穆蛱蝶属、线蛱蝶属、带蛱蝶属、律蛱蝶属和翠蛱蝶属；其中线蛱蝶属非单系群，翠蛱蝶属和律蛱蝶属则为单系发生，并构成姐妹群；缕蛱蝶属与环蛱蝶族亲缘关系较近。

Pollen morphology of 5 species in genus Tillandsia were observed by standard electronic modules. The results revealed the common features in their shape: i.e l-colporate and reticulate exine. All these showed that genus Tillandsia plants were more advanced in evolution than the other species within the same taxa.

在扫描电子显微镜下观察了5种铁兰属植物花粉的微形态，结果表明：铁兰属植物花粉的微形态具有一定的共性，即都具有1个萌发沟，花粉外壁都具网纹纹饰，说明铁兰属植物是自然类群中较进化的类群。

According to the life form of species and their roles in communities, 6 species groups are used to do ordination analysis and environmental interpretation. The result suggests that:①Despite the strong man-made disturbance at lower altitude sites, the number and character of evergreen species show an change along the altitude gradient.②The rare and endangered species concentrated at two sectors along altitude gradient, corresponding to the upper and lower borders of the mountain mixed forest belt of evergreen and deciduous broad-leaved species.③The pioneer tree species concentrated on the middle and upper positions at lower elevation.④The deciduous accompany tree species show a great diversity on middle and lower position at middle and higher elevation.⑤Coniferous species differentiate along elevation and local topographical gradient.⑥Deciduous species in Quercus, Castanea, Fagus, Carpinus genus as well as coniferous species play primary community-constructing roles at different topographical position at Dalaoling region.

根据物种生活型及其在植物群落中的地位，分6个种组进行排序和环境解释，表明：①尽管低海拔地段受到强烈人为干扰，常绿种类仍显示了数量和性质沿海拔梯度的变化；②珍稀物种在海拔梯度上形成两个相对集中的区段，大致对应于山地常绿落叶阔叶混交林带的上下边缘；③先锋树种在中低海拔的中上坡位富集；④在中、高海拔的中低坡位，落叶的乔木伴生种显示了极大的多样性；⑤为数不多的针叶树种在海拔和局部地形梯度上也有明确分异；⑥它们和落叶的栎、栗、水青冈、鹅耳枥属物种在大老岭地区不同地形部位的植被中起着主要的建群作用。

Using nuclear DNA C-values for 539 angiosperms in China, we examined the variation of these values among growth forms and taxonomic groups and the relationship of these values with invasiveness. Mean DNA C-value of the 539 angiosperm species was 4.06 pg. Mean DNA C-value was(1) significantly lower for woody species (1.84 pg) than for herbaceous species(5.02 pg);(2) significantly lower for 360 dicots (2.20 pg) than for 179 monocots (7.80 pg);(3) significantly lower for annuals (2.78 pg) than for perennials(6.65 pg);(4) significantly lower for 134 weed species (1.93 pg) than for herbaceous non-weeds (6.75 pg) and for several families that have an unusually high proportion of weed species;(5) significantly lower for 47 exotic weed species (1.76 pg) than for 134 native weeds (1.93 pg), but significantly lower than that of "non-weedy" herbaceous species (6.75 pg);(6) lower for weeds than for "non-weedy" species in same genus or family; and (7) in herbaceous species, generally lower for weedy compared to "non-weedy" species, with some exceptions such as Avena fatua, whose DNA C-value is as high as 14.15 pg, contrarily, and some "non-weedy" herbaceous species in Cruciferae and Cucurbitaceae with very low values.

统计了中国境内有分布的539种被子植物的DNA C-值，分析了它们在不同分类群、生活型、倍性、生活史类型以及在杂草和非杂草类群中的分布情况，主要结果如下：(1)539种被子植物DNA C-值平均为4.06 pg，其中木本植物的DNA C-值平均为1.84 pg，低于草本植物的平均值(5.02 pg)；(2)双子叶植物(360种)的DNA C-值平均为2.20 pg，极明显地小于单子叶植物(179种)的平均值(7.80 pg)；(3)1年生植物的DNA C-值平均为2.78 pg，明显小于多年植物的平均DNA C-值(6.65 pg)；(4)134种杂草的DNA C-值平均为1.93 pg，明显小于非杂草草本植物的平均值(6.75 pg)，含杂草较多的科，平均DNA C-值相对较小；(5)统计的47种入侵杂草的DNA C-值平均为1.76 pg，略小于134种杂草的平均DNA C-值(1.93 pg)，极显著地小于非杂草性草本植物(6.75 pg)；(6)以科为单位，不同科的DNA C-值存在着极大的差异；(7)DNA C-值与染色体倍性的关系并不明显，但是，随着倍性的增加，基因组变小；(8)在同一科、属中，与非杂草相比，典型杂草的DNA C-值往往偏小；(9)总体上杂草或杂草性强的植物，它们的DNA C-值比非杂草性植物的要小。

Topological structure of the molecular phylogenetic tree, constructed by 16S rRNA gene with Neighbor-Joining method, revealed that all species of Helice from Sesarmidae and two species of Hemigrapsus from Varunidae were clustered into one branch, two species of Sesarma from Sesarmidae were clustered into another one, Grapsus albolineatus from Grapsidae and Plagusia tuberculata from Plagusiidae were formed one absolute branch respectively. The molecular analysis showed that the genus Helice indeed must be considered to be Varunidae, because it formed a monophyletic group with the genus Hemigrapsus yet not the Sesarmidae.

Through the traditional physiological and biochemical method, together with the 16SrDNA sequence homology and phylogenetic analysis, the strains were identified. The result shows they belong to the genus photobacterium, but they differ from any species of this genus in some characteristic which suggests they might be new species, and their taxonomic placement needs more information on genes level.

Our interpretation of the results from parsimony, distance and maximum likelihood based phylogenetic analyses suggest:(1) African colobines and Asian colobines have been independent evolutionary entities for a long time; the divergent time is estimated to occur 10 million years ago based on a molecular clock of 2% substitution per site per million years;(2) both Rhinopithecus and Trachypithecus could be regarded as separate genus;(3) Pygathrix and Rhinopithecus are sister groups while Presbytis and Trachypithecus are closely related;(4) both the Sichuan and Yunnan snub-nosed monkey represent valid species respectively;(5) within genus Trachypithecus, T. phayrei is closely related to T. cristatus and T. auratus, while T. francoisi is distinct from them; the white-headed leaf monkey, however, should be a subspecies of T. francoisi;(6) within genus Presbytis, P. thomasi should be separated as a valid species from P. melalophos, but the genetically divergent degree between P. comata and P. melalophos implies that P. comata may just be a subspecies of P. melalophos.

结果表明：（1）非洲疣猴与亚洲疣猴的分歧已非常明显，按分子钟推算的分歧时间约在1，000万年前；（2）Rhinopithecus和Trachypithecus均应成为独立的属；（3）白臀叶猴属与金丝猴属关系较近，Presbytis属和Trachypithecus属关系也较近；（4）我国的川、滇金丝猴应分别被视为独立的物种；（5）在Trachypithecus属中，菲氏叶猴与银叶猴(T.cristatus)和乌木叶猴亲缘关系较近，黑叶猴(T.francoisi)则与它们的关系较远，曾被怀疑为一个种的白头叶猴(T.f.leucocephalus)应只是黑叶猴的一个亚种；（6）在Presbytis属内，托氏叶猴应从僧帽叶猴(P.melalophos)中独立出来成为一个有效种，但我们的结果倾向于将灰发叶猴置为僧帽叶猴的一个亚种。

Results We discovered and confirmed that there were 17 different species of 1st intermediate host of in Paragonimus Jiangxi, covering 2 families and 3 genera, and 23 different species of 2nd intermediate host, covering 1 order, 1 family and 3 genera, 15 of which were reported to be new species by the authors. Furthermore, a new genus of Jiangxi Huananpotamon was built up, based on the assumption that Wuyi mountain range is the developing centre of Huananpotamon , and tend to spread out towards Jiulian mountain of Nanling mountain range adjacent to Guangdong Province and Luoxiao mountain range next to Hunan Province. In addition, Jiangxi Province freshwater crab order was created at the end of research, as well as a complete classification and retrieval table of its order and genus. The authors also proved that the advantageous stocks of freshwater crabs carrying encysted metacercaria of Jiangxi Paragonimus westermani were Sinopotamon fukiense and S.wanzaiense .
