Adult male guppies reach a size of approximately 1.2 inches and adult female guppies reach a size of about 2.4-2.5 inches. It is best to keep at least 2-3 females per each male because male guppies often harass the females. Plants are also good so that the female has plenty of hiding ...
Female traits associated with energy use and locomotion are especially likely to be prone to plastic or evolutionary change via male harassment. For example, an increased aerobic or anaerobic capacity, or improved maximal loco- motory performance, could allow females to resist coercio...
Guppies should have huge variations in the color of their patch, depending on how much algae they eat. Why has it stayed the same hue of orange? Researchers at theUniversity of California, Los Angeles (UCLA)learned that female guppies are drawn strongly to males with intermediate levels of dr...
所有类型孔雀鱼的理想佳肴,促进它们发挥最自然的美。 5. Likeguppies, male crickets compete for female favour-though by virtuoso chirping, rather than visual displays. 像孔雀鱼一样,雄性蟋蟀也要争夺雌性的青睐,虽然他们使用的是音乐大师般地动听啁啾,而不是视觉盛宴。 单词专题...
Sneak copulation and male-male aggression had no noticeable effect on male mating success. Mating success was strongly related to the frequency of female behavioural responses to both displaying and non-displaying males. Relative area of orange colouration and complexity of male colour patterns were ...
The meaning of GUPPY is a small bony fish (Poecilia reticulata of the family Poeciliidae) especially of Barbados, Trinidad, and Venezuela that is a live-bearer and is often kept as an aquarium fish.
Under orange light, there was no relationship between male colour pattern and female sexual response, but under white and blue light treatments there was such a relationship. Other male ornaments were not preferred by females either under normal lighting conditions or when their ability to use ...
The purpose of this chapter is to investigate the relative importance of a variety of male traits in mate choice by female guppies. Guppies are small, sexually dimorphic, live-bearing fish native to Trinidad and Tobago and to neighboring parts of South America. Because of the males' conspicuous...
This strategic increase in mating effort could result in higher male reproductive success because mating attempts towards receptive females are likely to be less costly and males could have a greater probability of fertilisation. 展开 关键词: Sexual selection Male mate choice Mating strategies Female ...
