繁殖的

Improving animal reproductivity is an aim of biology of reproduction , also, an question which were be resolved in husbandry.

提高动物繁殖力一直是生殖生物学研究的目标，也是畜牧业中必须解决的关键性问题，类固醇激素合成能力的强弱是影响繁殖力的一个重要因素。

When food and water were abundant, the density dependent social factor did not affect the reproductivity, which implied that food instead of social factor might be the key factor in determining the change of reproductivity of the hamster in field.

在食物和水分充分供应的情况下，围栏内种群密度的高低对雌鼠繁殖力的影响不大，说明食物可能是引起野外大仓鼠种群繁殖力变化的关键因素，而社群因素的作用不大。

The mains results are as follows: 1,In Scirpus speices, the allocation to sexual reproductive ramets and vegetative ramets varied with environmental conditoin and life history stages. This makes the species adapt to tidal flat stresses and utilize heterogenetiously distributed resources.

主要结果有： 1，海三棱麃草中，随年龄增加和生境改变，植物的有性繁殖和营养繁殖构件的生长速率，以及球茎贮存物质的比例发生改变，这种特性使物种适应高胁迫下的潮滩生境，同时提高了植物体利用异质性资源的能力。

Spinulosa decreased significantly when the water depth was more than 2 meters, as well as the sexual reproduction strategy of V.

随着水位的变化，有性繁殖体的投资比率发生变化，从水深1.4 m的2.77% 0.96%到水深2 m的0.13% 0.22%；而无性分株繁殖方式水深2 m以下没有显著差异。

Spinulosa in the Xiling Lake were affected by water depth gradient.

调查研究西凉湖的刺苦草（V.spinulosa）在不同水深下的生长和繁殖策略，试图弄清是否水位的变化影响刺苦草的繁殖策略，进而影响刺苦草在湖泊中的分布情况。

In order to investigate the effects of different shading levels (Shading levels were: control 0, 50%, 80%, 90%) on the trade-off relations between sexual reproduction and clonal multiplication of Vallisneria spinulosa, a natural greenhouse experiment was carried out by winter tuber of Vallisneria spinulosa being collected from Poyang Lake in the Jiangxi Province.

以采自江西鄱阳湖的刺苦草冬芽为实验材料，在自然温室中经历了全不遮阳、部分遮阳等4种处理，研究不同遮阳处理产生的光线差异对刺苦草的有性繁殖和无性繁殖方式的资源配制的影响。

Only known species of Cycliophora; lives symbiotically attached to a lobster's lip by an adhesive disk and feeding by means of a hairy mouth ring; its complex life cycle includes asexual and sexual phases.

通过带有粘性的圆盘附着共生在龙虾的唇边，通过带毛的嘴环进食；其复杂的生命周期包括无性繁殖和有性繁殖阶段。

通过带有粘性的圆盘附着共生在龙虾的唇边，通过带毛的嘴环进食；其复杂的生命周期包括无性繁殖和有性繁殖阶段。像疯狗一样发疯

Functions in rodent reproduction behavior were discussed, difference between functions of vomeronasal system and main olfactory system in rodent behaviors were compared in this paper.

通过对犁鼻器在鼠类繁殖行为中的功能研究，并将其与主要嗅觉系统的功能进行比较，发现虽然犁鼻器是一个微小的、而且常常是被人们所忽视并有争论的器官，但它在鼠类行为，尤其在繁殖行为方面具有多种功能。

Farther, the sperm DNA of wild male was extracted from copulated wild female thelycum in three families of the ten.

从其中3个家系的雌性亲虾纳精囊中提取了雄虾精子DNA，微卫星标记显示各家系的子代个体均有一个等位基因与雄性亲虾的基因型相符，且符合孟德尔遗传规律，这为野生中国明对虾雌虾在繁殖季节一对一的繁殖行为提供了遗传学的证据。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
