In the guppy Poecilia reticulata, females often choose their mates on the basis of the orange spot coloration of males. It is known that the colour saturation of orange spots in males is determined by the amount of intake of algae, a natural source of carotenoids. In this study, we examined the relationship between sexually selected traits in wild-caught males and their algal-searching ability ...

Green synthesis of nanoparticles supports reuse, reduce and recycle concept towards the environmental friendly synthesis and also produce the good results compare to chemical methods in some of the cases. MgO nanoparticles can be prepared by solution combustion synthesis using citric acid is a fuel. The same citric acid is available in the nature in so many form just like tamarind, lemon and or...

*Correspondence: Devi Stuart-Fox, Zoology Department, The University of Melbourne, Building 147, Royal Parade, Parkville, VIC 3010, Australia e-mail: [email protected] Female signals of reproductive status often comprise both distinctive color patches and behaviors but their relative influence on male courtship investment is unclear. We examined the role of female-specific coloration in sign...

introduction: the spatial variability of soil properties and its importance in production is a matter-of-debate. insight about the variability of soil properties as well as the yield of orchards is necessary to achieve higher productivity and better management. orange is one of the most important export products in our country and to sustainable production of this product, it is necessary to id...

The mechanistic bases of natural and sexual selection on physiological and behavioral traits were examined in male morphs of three colors of the side-blotched lizard, Uta stansburiana. Orange-throated males are aggressive and defend large territories with many females. Blue-throated males defend smaller territories with fewer females; however, blue-throated males assiduously mate guard females ...

the use of orange peel as low-cost and eco-friendly adsorbents has been investigated as an ideal alternative to the current expensive methods of removing dyes from wastewater. this paper concerns with the removal of blue 56 from aqueous solutions by orange peel. the effects of ph , initial concentration, adsorbent dosage, and particle size of adsorbent, temperature and also isotherm data analys...

Local guilds define groups of species that share common resources and coexist in space and time. Local guilds have historically been a major focus of community ecology; however, studies of local guilds rarely measure consequences of coexistence for fitness-related traits or test predictions of alternative hypotheses for how species may interact. We studied consequences of coexistence for Orange...

The fitness of male guppies (Poecilia reticulata) highly depends on the size and number of their black, blue, and orange ornaments. Recently, progress has been made regarding the genetic mechanisms underlying male guppy pigment pattern formation, but we still know little about the pigment cell organization within these ornaments. Here, we investigate the pigment cell distribution within the bla...
