Guppie For the past 500,000 years, Guppies have changed their color dramatically, but yet an orange patch on males has remained unchanged.It’s all about romance. Or maybe it’s just about doing what you have to do to get the ladies. Females like the orange patch, which contains two pi...

Here, we exposed male guppies (Poecilia reticulata) for a short period (21 days) to an environmentally realistic concentration (1 ppb) of PFOA, a legacy PFAS, and its replacement compound, GenX, to assess their impact on reproductive traits and gene expression. Exposure to PFAS did not ...
Even though male guppies can inseminate non-receptive females, we only found high levels of courtship between males that were with a receptive female rather than a non-receptive one. Although there was little affect of female receptivity on male-male competition, we found that males chased and ...

In the wild, male guppies spend a large part of their time budget attempting to mate with females, with females in some populations receiving more than one coercive mating attempt per minute (Magurran & Seghers 1994b). Harassment by male guppies can consist of repeated bouts o...
"Insight into exchanges between male and female genes have helped explain how these bright colours have evolved and diversified in male guppies," says Dr. Roberta Bergero, School of Biological Sciences. More information:Roberta Bergero et al. Exaggerated heterochiasmy in a fish with sex-linked ...
