繁殖投入,reproductive investment
1)reproductive investment繁殖投入
1.By using parameters of maternal reproduction and offspring development of root vole(Microtus oeconomus),the effects of maternalreproductive investment on the quality of offspring were analyzed.本研究在实验室条件下,利用根田鼠母体繁殖和子代发育参数,分析其母体繁殖投入对子代质量的影响,目的在于探讨子代胎仔数与胎仔质量间的权衡理论。
2.The results showed that:(1)The larger of individual size,the higher ofreproductive investment and the lower of reproductive allocation;(2)With the increasing of individual size,female function investment,male function investment and attractive structures investment increase.于各物种花中前期对青藏高原东部高寒草甸6种多年生龙胆属植物花期的繁殖分配和性分配进行分析,结果表明:(1)多年生龙胆属植物的植株个体越大,繁殖投入越高,繁殖分配越低;(2)随着植物个体的增大,对雌性、雄性和吸引结构的投入都在增加,这可保证资源的充分利用,不会因为单一部分的增加而造成资源的浪费;(3)6种龙胆属植物中,有4种其性分配结果与性别分配(SDS)的理论预测一致,即大个体更偏向雌性器官的资源投入,但麻花艽(Gentiana atraminea)和达乌里秦艽(Gentiana dahurica)的性分配与个体大小则没有表现出负相关,可能与其本身具有的雌雄异熟———雄性先熟特点有关;(4)资源在雌雄功能间的分配没有表现出权衡关系,可能是由于植物必须在许多不同生活史性状之间进行资源分配,而不是两两之间非此即彼。
2)Reproductive effort繁殖投入
1.Reproductive efforts and growth characteristics of five plants grown at alpine meadow ecosystem were measured to test the effects of enclosure treatment and imitating global warming on plants.通过对高寒草甸生态系统金露梅灌丛、矮嵩草草甸、围栏矮嵩草草甸以及模拟地球增温效应下5种植物繁殖投入和生长特性的测定,结果表明,矮嵩草、麻花艽、苔草以及美丽风毛菊的叶长沿对照矮嵩草草甸、0TC、围栏以及金露梅灌丛呈现上升趋势,只是灌丛中苔草和麻花艽两种植物的叶长较围栏和OTC有所下降,而环境变化对植物的叶宽的影响较小。
3)reproductive effort繁殖投资
1.Studies on these four types of plants showed results as follows: in contribution to new generation of individual plant,OL made the most while UL made the least,in reproductive allocation,plants from OL had most resource allocation to sexual reproduction yet UL had the least,which caused differences inreproductive effort and repr.对4种类型种子实生植株的研究表明,4种类型种子实生植株个体水平上对新种群的贡献具有差异,地上大种子表现为最大,地下小种子则最小;4种类型种子实生植株在资源的繁殖配置上存在着差异,大种子尤其地上大种子对有性繁殖的资源分配最大,而地下小种子最小,这种差异又决定了在繁殖投资和繁殖代价上的差异,小种子特别是地下小种子实生植株的繁殖投资最小,而大种子特别是地上大种子实生植株的繁殖投资最大;从繁殖代价来看,大种子实生植株的繁殖代价之间差异不显著,而大种子实生植株的繁殖代价显著小于小种子实生植株的,地上小种子实生植株的繁殖代价显著小于地下小种子实生植株的。
4)reproduction investment生殖投入
1.Thereproduction investments of each clutch are 0.崇安地蜥为多次产卵型,窝卵数2~4枚;产卵前1天就表现焦躁不安,不食;每窝生殖投入分别为0。
5)reproductive investment strategy繁殖投资策略
6)reproduction[英][,ri:pr?"d?k?n][美]["ripr?"d?k??n]繁殖

2.Cadmium effects on growth and development as well asreproduction of Boettcherisca peregrine in the parental generation and first filial generation.;重金属镉对棕尾别麻蝇亲代及子代生长发育与繁殖的影响
