The Sublethal Effects of Low-pH Exposure on the Chemoreception of Poecilia sphenops
Archives of Environmental Contamination and Toxicology, 2008In this study, Poecilia sphenops (gold mollies) were chronically exposed to low pH that mimic those found in natural environments, e.g., rivers and lakes. The Poecilia sphenops were placed in two separate aquaria with pH levels of 5 and 6 and presented with a different chemically mediated behavioral challenge of locating the food source.

Molecular Phylogenetics and Evolution, 2013
We inferred the phylogenetic relationships among members of the Poecilia sphenops species complex to resolve the colonization process and radiation of this group in Central America. We analyzed 2550 base pairs (bp) of mitochondrial DNA (mtDNA), including ATP synthase 6 and 8, cytochrome oxidase subunit I and NADH dehydrogenase subunit 2 genes, and ...

Changing the Stimulus ♀ induced in ♂♂ of the poeciliid fish Poecilia sphenops a strong increase of copulation attempts, nipping and gonopodial swinging (“Coolidge effect”). There was a similar increase of sexual activities after social isolation of 23 hours and reintroducing the same ♀ like before.

Gamma-aminobutyric acid (GABA) functions as the primary inhibitory neurotransmitter within the central nervous system (CNS) of vertebrates. In this study, we examined the distribution pattern of GABA-immunoreactive (GABA-ir) cells and fibres in the CNS of the viviparous teleost Poecilia sphenops using immunofluorescence method.

Temperature tolerance polygon of Poecilia sphenops Valenciennes (Pisces: Poeciliidae)
Journal of Thermal Biology, 2002Abstract 1. The critical thermal maximum (CTMax) and minimum (CTMin), the upper and lower incipient lethal temperature, and the high and low avoidance temperature of Poecilia sphenops were established. 2. The area of thermal tolerance of P. sphenops upon considering the lethal limits was 863.9 (°C) 2 , the estimated area using the critical ...

Possible decision-making preadaptations in the molly Poecilia sphenops
Animal Cognition, 1999In many species females choose a mate from among several available males; in other species, the social system provides no apparent opportunity for making a decision among alternative suitors, and decision-making capacity is assumed to be minimal. The origins, bases, and logic of female mate choices are contentious questions with important cognitive ...
