查询词典 dispersal

GM seeds and crops can easily cross contaminate wild and domestic plants through wind-borne pollen, seed dispersal, volunteers, and horizontal gene transfer.

虽然"可能会破坏生态"常常被做为反对种植转基因作物的一大理由，但是这种可能性并没有变为现实。

This is an instance of arrested allopatric speciation due to genetic homogenization via rare long distance dispersal.

此研究提供了经由少数个体长距离扩散事件，导致族群遗传均质化的结果，遏止了长时间隔离造成的异域种化的案例。

Spores await dispersal and germinate in favourable conditions for amoeboid growth. However, the formation of stalk cells is a process of cell death.

在合适条件下，孢子细胞萌发开始新生命周期；而柄细胞无论用什么条件都不能萌发，因此柄细胞是死亡细胞，柄细胞的形成是细胞凋亡的过程。

Objective Analyzing the changes of QT dispersal degree of cardiogram of unstable anginal patients and healthy adults and exploring the effect on QTd of unstable anginal patients by using β1 retarder-metoprolol.

目的分析不稳定心绞痛患者与健康成人心电图QT离散度变化及探讨选择β1受体阻滞剂—美托洛尔对不稳定心绞痛患者QTd的影响。

Species with poor dispersal ability of sedentary behavior are likely to become rare as a result of anthropogenic factors.

扩散能力弱或有固着行为的物种，很可能由于人类因素而成为稀有的。

Colour, a kind of stable and effective visual signal which is epigamic to animals for pollination and seed-dispersal, sometimes could become aposematic signal to herbivores.

因此，向潜在的植食动物传达自己的防御信号对植物是有益的。

All these microsatellites can be used in the study of Castanopsis chinensis genetic diversity, mating system, and pollen flow or seed dispersal.

这些引物可用于锥栗的遗传多样性、交配系统和花粉及种子扩散水平的研究，为研究锥栗的居群遗传学和保护生物学提供了良好的基础。

In the present study, we examine the chloroplast genomes of Ceriops tagal along the coasts of both sides of the Kra Isthmus to retrace divergence events and to evaluate the probability of previous long distance dispersal.

在此研究中，我们利用了母系遗传的叶绿体DNA作为分子标帜，试图追溯分布在克拉地峡两岸的红树林之细蕊红树是否受到马来半岛的隔离影响，导致遗传上的分歧，进而评估横跨海域的长距离扩散的可能性。

Low genetic variation has probably resulted from the refugial nature of these populations since the last glaciation rather than from recurrent pollen dispersal between Chilanshan and Alishan populations of these 2 Chamaecyparis species. Two Hinfl restriction site differences were found in the trnV-trnM intergenic spacer between C. formosensis and C. taiwanensis. Fragment length difference as well as point mutations in the petG-trnP intergenic spacer between C. formosensis and C. taiwanensis were also found.

如此低的遗传变异可能是因为现今之红桧与台湾扁柏族群为冰河期存在之大族群的残留小族群，而未必是花粉散播所提供之基因交流极为频繁所造成。trnV-trnM基因间区间序列在红桧与台湾扁柏两者间有两个HinfI之酶切点之差异，在PetG-trnP基因间区间序列也发现台湾扁柏与红桧之间有限制酶片段长度及其他点突变。

In C. indicus, the infected mechanism correlated with season. The infusoriform larvae of dicyemid mesozoan dispersal from the host to sea water in the autumn and winter, then entering host in the spring and summer. The change of dicyemid life cycle stage in the C. indicus kidney correlates with the sharp decrease of infection intensity. However, the dicyemid infection in Octopus marginatus correlates with body size, not with season.

在C。 indicus之分析中可发现，中生虫之感染与季节有关，有性幼体於秋、冬季自寄主章鱼体内扩散至外界，并於春、夏季大量进入寄主，接著在寄主体内发展，每一次生活史之时期转变，伴随著感染强度之骤降，直至成熟之菱形体时期，大量有性幼体出现肾腔中，至秋季有性幼体随寄主尿液排至外界，下一个生活史之循环接著开始。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
