Male birds of species that form long-lasting pair-bonds often continue to make elaborate displays of plumage, color and dance after they mate with a female, encouraging the female to invest more energ...
A study of lemur scents funded by the National Science Foundation and conducted by researchers at Duke University finds that an individual's distinctive body odor reflects genetic differences in its i...
Scientists know that there is a thermal window when half-centimeter-long insects called treehoppers are active and looking for mates. Male tree hoppers produce songs to attract females, and females us...
If you are a male barn swallow in the United States or the Mediterranean with dark red breast feathers, you’re apt to wow potential mates. But if you have long outer tail feathers in the United States...
Yerba Mate (Ilex paraguariensis), a tea known for its high antioxidant content, was supplemented to 30 of 60 ewes for 13 wks to assess its effect on their productive performance. A 2.5% inclusion rate...
There have been several approaches to the problem of provisioning traffic engineering between core network nodes in Internet Service Provider (ISP) networks.
We determined the probability of mating as a function of population density in the estuarine copepodAcartia hudsonicaby combining experimental measurements with a simple model. Pairs of unmated copepo...
摘要多药和有毒化合物排出家族(Multidrug and Toxic Compound Extrusion, MATE)是一个新的次级转运蛋白家族,此类转运蛋白对氨基葡糖、阳离子染料、多种抗生素和药物有转运作用。拟南芥中的MATE基因家族是一个多基因家族,大概由56个成员构成,本文综述了拟南芥中MATE家族基因的研究进展,包括3个方面:第一是拟南芥中MATE家族成员的构成及主要特征;第二描述了转运...
Three-dimensional (3D) video observations of free-swimming copepods revealed the mechanisms of mate finding in the cyclopoid copepod Oithona davisae (cephalothorax length 0.33 mm). The females are amb...
Mate encounter rates in pelagic copepods depend on the characteristics of the mate detection mechanism as well as on the motility patterns and concentrations of males and females. We describe male an...
