Evolution Of Lemur Pelage Color Variation, Amanda Nicole Spriggs
Evolution Of Lemur Pelage Color Variation, Amanda Nicole Spriggs
Legacy Theses & Dissertations (2009 - 2024)
This dissertation investigates the selective pressures that may be driving variation in pelage color patterns in Eulemur, Varecia, and Propithecus. This is addressed by exploring the relationship between the lemur pelage colors and ecological variables, such as habitat type, predation pressures, visibility variables, and level of sympatry. The following model is presented here to describe the evolutionary mechanisms that are thought to be maintaining pelage coloration in lemurs: Pelage color and pattern are potentially used to (1) signal to conspecifics information such as mate quality, (2) signal to congenerics species identity, and (3) avoid signaling the individual’s presence to predators. …
