pose is the guppy (Poecilia reticulata), a small poeciliid fish inhabiting freshwater streams throughout Trinidad. Guppies have provided some of the best examples to date of the adaptive use of alternative mating strategies Communicated by J. Krause J.P. Evans () A. Pilastro Dipartimento di Biologia, Università di Padova, via U. Bassi 58/B.   It’s not always easy to tell if a fish is male or female: they look more or less the same. But there are exceptions, such as guppies and, as .

ABSTRACT. In this work we describe for the first time the social and reproductive behavior of the Neotropical fish Cichlasoma dimerus (Heckel, ) [Perciformes: Cichlidae], endemic to the Paraná River basin, using a comprehensive-integral approach, including morphological and physiological features. This substrate breeding fish has biparental care of the fry and presents . Most guppy breeders love variety this is usually why they pick guppies in the first place. But raising a large variety of different types properly takes a great many tanks and a lot of space. It is .

Guppy Edition of the Bachelor: Color Variation Affecting Sexual Behavior in the Male Guppy Poecilia Reticulata, or the “common guppy”, is a beautiful aquatic species that displays uniquely strong sexual tendencies in efforts to attract the opposing Author: James Teel, Kenneth Wolgamott, Zackary Terry, Michael Cobbs. Abstract: Testes and ovaries compose the primary reproductive organs in fishes. Mostly, the gonadal structures remain paired and are of similar sizes, which remain partially or totally fused. Some secondary reproductive organs in fishes may remain present which increases its reproductive potency (Guimaraes-Cruz et al., ).File Size: KB.

The effects of sexual experience and female receptivity on courtship-rape decisions in male guppies, Poecilia reticulata An analysis of sexual behavior and reproductive physiology in the guppy, Lebistes reticulatus (Peters). Ph.D. thesis, New York University.

Liley, N. Cited by:   Experiments were designed to determine the effects of male pigmentation patterns on female choice in guppies. When presented with a series of variably-colored males, females of different genetic strain consistently exhibited similar preferences (Tables 1 and 2), preferring those males with the greatest development of both carotenoid and iridescent pigments (Table 3).Cited by: Sexual maturity in guppies varies between males and females; it also depends greatly on the conditions of the water, food supply and other factors.

In captivity, males can reproduce around 1 month of age, but they reach true sexual maturity around the middle of their third month. Females don't reach reproductive maturity until around 3 months old.

Female behaviour mediates male courtship under predation risk in the guppy (Poecilia reticulata) on Lebistes reticulatus the sexual behaviour of male Trinidadian guppies was studied to. analysis of sexual behaviour and reproductive physiology in the Guppy The female of guppy fish were found to copy the mate choice behaviour of other female in competition.

A suite of male guppy sexual characteristics that is routinely Cited by: Introduction. The post-reproductive segment of the human lifespan is often considered to be an adaptive feature of aging, since post-reproductive women can make significant contributions to the fitness of their children and grandchildren [1,2].Although there is published evidence for the adaptive significance of the post-reproductive life stage in humans [], few formal empirical Cited by: 1.

Anim Behav. Apr-Jul;16(2) The endocrine control of reproductive behaviour in the female guppy, Poecilia reticulata peters. Liley by: In four years (or about seven guppy generations), the brightest males are beginning to bear the brunt of the predation pressure, while the drabbest guppies in the population dominate.

Although Trinidadian populations of the guppy, Poecilia reticulata, show considerable adaptive genetic differentiation, they have been assumed to show little or no reproductive isolation. We tested this assumption by crossing Caroni (Tacarigua River) and Oropuche (Oropuche R.) drainage populations from Trinidad's Northern Range, and by.

This is sexual selection at work, and it is the force that pushes guppy coloration toward conspicuousness just as hard as predation pushes coloration toward drabness.

Abstract. In this study we investigated the environmental regulation of daily reproductive activity of guppies (Poecilia reticulata).We observed male guppy reproductive behaviour for 17 days over three time periods (dawn, noon, and dusk) while recording natural variation in water temperature and light by: The study of post-reproductive lifespan has been of interest primarily with regard to the extended post-menopausal lifespan seen in humans.

This unusual feature of human demography has been hypothesized to have evolved because of the “grandmother” effect, or the contributions that post-reproductive females make to the fitness of their children and grandchildren.
