Food availability and parasite infection influence mating tactics in guppies (Poecilia reticulata)

Despite the important effects of diet and parasite infection on male reproductive behavior, few studies have simultaneously addressed their influence on intrasexual selection (male–male competition). We examined the synergistic effects of 2 naturally varying environmental factors, lifetime food intake and infection, with the monogenean parasite Gyrodactylus turnbulli on the mating tactics and f...

The effects of resource availability on alternative mating tactics in guppies (Poecilia reticulata)

Food availability can influence the optimal allocation of time and energy among alternative behaviors such as foraging, courting, and competing for mates. If populations differ consistently in food availability, selection may cause geographic divergence in allocation strategies. At the opposite extreme, a norm of reaction may evolve such that food intake influences the allocation strategy of in...

Systemic Granulomatosis in Guppies Poecilia reticulata

In many guppy Poecilia reticulata farms in the vicinity of Bangkok, diseases have caused longlasting fish death and consequently large cumulative mortality. Diseased guppies were collected and subjected to histopathological analysis. The analysis revealed systemic granulomatosis as a remarkable histological sign. Rod-shaped bacterial cells with strong acid-fastness were found in the granulomas....

Countergradient variation in the sexual coloration of guppies (Poecilia reticulata): drosopterin synthesis balances carotenoid availability.

Trinidad guppies (Poecilia reticulata) are distributed along an environmental gradient in carotenoid availability that limits the carotenoid content of the orange spots of males. The amount of synthetic red pteridines (drosopterins) in the orange spots covaries with the carotenoid content, such that the ratio of the two types of pigments is roughly conserved across streams. Carotenoids and dros...

Observational Learning and Predator Inspection in Guppies (Poecilia reticulata)

Prior work has demonstrated that, following a predator inspection visit of their own, guppies prefer to associate with individuals who inspected a predator most closely. Based on this work, as well as studies of social learning in the context of mate choice, we predicted that male guppies that observed but did not participate in an inspection trial would subsequently choose to associate with th...
