We posit that agouti pelage is broadly adapted to a range of heterogeneous conditions created by fire. Light-colored (less melanistic) squirrels were positively associated with increasing proportion of cropland in a fox squirrel dispersal buffer. Agouti-colored squirrels were positively associated with increased proportion of burned area in a fox squirrel dispersal buffer.
#Fox squirrel drivers#
Building upon previous research that investigated the drivers of melanism, we measured fox squirrel pelage coloration across the visible light spectrum. hereafter, fox squirrel) as a model species to investigate the role of environmental factors on pelage coloration. We used the polymorphic eastern fox squirrel ( Sciurus niger ssp. The environmental drivers of color polymorphism are poorly understood. In spatially and temporally heterogeneous environments, some species exhibit multiple distinct color patterns within a population (i.e., color polymorphism).
#Fox squirrel skin#
The color patterns of an animal’s pelage, feather, or skin serve a variety of adaptive functions importantly, one function is concealment through background matching.

The arrival of fox squirrels offers an opportunity to study, first-hand, the ecology of an introduced species, and you can help! Our survey is open year-round. First reported in 2011 along the Jordan River in Salt Lake City, this tree squirrel has been spreading throughout northern Utah.

The fox squirrel ( Sciurus niger), a species native to the eastern US, has recently become established in Utah.
