Experience-Dependent Color Constancy in Guppies (Poecilia reticulata)
We investigated the ability to recognize the color of surfaces in fish (Poecilia reticulata), bred from birth in conditions of artificial light with constant spectral content. The capacity for color constancy significantly deteriorated when compared that to the control group. Further alteration of lighting conditions and transfer into natural daylight conditions restored the suppressed function...
متن کاملSystemic 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....
متن کاملFamiliarity affects collective motion in shoals of guppies (Poecilia reticulata)
The coordinated and synchronized movement of animals in groups often referred to as collective motion emerges through the interactions between individual animals within the group. Factors which affect these interactions have the potential to shape collective movement. One such factor is familiarity, or the tendency to bias behaviour towards individuals as a result of social recognition. We exam...
متن کاملRapid evolution of escape ability in Trinidadian guppies (Poecilia reticulata).
Predators are widely assumed to create selection that shapes the evolution of prey escape abilities. However, this assumption is difficult to test directly due to the challenge of recording both predation and its evolutionary consequences in the wild. We examined these events by studying natural and experimental populations of Trinidadian guppies, Poecilia reticulata, which occur in distinct hi...
متن کاملShort-term dietary supplementation with the microalga Parietochloris incisa enhances stress resistance in guppies Poecilia reticulata
Two trials were conducted to determine the e¡ects of dietary enrichmentswith themicroalgaParietochloris incisa, rich in arachidonic acid (ARA), on stress resistance in guppies Poecilia reticulata.The microalgawas added to commercial diets as a neutral lipid (NL) extract and its fractions or as broken cells. Experimental diets were applied for a period of 14 days. In trial 1, commercial diets we...
