查询词典 dispersers

So frugivorous birds also acted as the main dispersers of these alien species.

因此，鸟类是这些栖木下方外来植物种类的主要传播者。

The ecological values of dung beetles were reviewed, including dung transferring to underground, secondary seed dispersers, pollination, biological control, intermediate hosts of parasites, broadly applications, bionic and theory importance. The imminency and signification of dung beetles conservation were proposed.

文章系统介绍蜣螂的生态价值，包括转将运粪便到地下、对种子二次传播的作用、传粉作用、对有害生物的控制作用和寄生虫的中间宿主，以及广阔的开发应用前景、重要仿生学意义和重大理论意义；并进一步提出蜣螂保护的迫切性和重要意义。

The finding dovetails with the paleobotanical record, which shows that the flowering plants had just invented a veritable cornucopia of new fruits, flowers, gums and nectars with which to entice pollinators and seed dispersers.

这一发现正与古植物学记录相吻合，当时开花植物刚发展出十足丰盛的新式果实、朵、脂、蜜，藉此吸引授粉者和种子传播者前来。

Rodents, bats, birds and ants are all important seed dispersers.

啮齿动物，蝙蝠，鸟和蚂蚁都是重要的种子扩散者。

In recent years, many studies have suggested that the selective pressure be-tween dispersers and plants is rather weak.

然而，食果动物和植物一对一的协同进化的例证并不多见；适合种子萌发和生长的环境在时空上难以确定；食果动物和植物的进化速度不一致；植物与种子传播者的选择压力存在着高度的不对称和不平衡，加上环境因素的重要影响，这种选择压力受到极大的限制而有可能变得不显著。

Their biological function is unknown; they may attract pollinators and seed dispersers.

类黄酮的生理功能虽然还没有被确切肯定，但它们可能吸引蜂、蝶和散布种子。

This suggests that, in evolutionary terms, having antioxidants present in fruit would make a plant more successful at attracting seed dispersers.

这表明，在进化而言，具有抗氧化剂的果实，使植物更成功吸引种子传播者。

This suggests that, in evolutionary terms, having antioxidants present in fruit would make a plant more successful at attracting seed dispersers.

这暗示着在长期的进化进程中，含有抗氧化剂的果实能使得植物更成功得吸引鸟类的注意从而传播种子。

Hence birds acted as the main dispersers of these invaded plants in the hedges.

因此，鸟类是树篱中侵入植物的主要传播者。

The results showed that the rate of mating disruption was 71.1%-80.7% caused by 150-750 rubber pheromone dispersers per hm 2. The egg numbers were reduced by 79.4%-86.1%, 72.9%-84.7%, 58.3%-65.1% and 58 9% at the treatments of 750, 300-375, 120-150 and 30 rubber dispersers per hm 2, respectively. In large scale disruption demonstrations, numbers of egg masses decreased 82.4% and 73.2% at placements of 60 dispersers per hm 2 in mid season rice seeding paddy and in early season transplanting paddy, respectively.

结果表明，田间放置诱芯150～750个/hm2的迷向率为71.1%～80.7%；每公顷放置诱芯750、300～375、120～150个和 30个的迷向区卵量比对照区分别下降79.4%～86.1%、72.9%～84.7%、58.3%～65.1%和58.9%；每公顷放置60个诱芯的大面积迷向示范区中稻秧田和早稻大田卵块量分别比对照下降 82.4%和73.2%，早稻大田枯鞘丛率比对照下降70.4%。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
