Evaluating the practicality, economic, and sampling efficiency of potential monitoring programs is a first step in validation. Thus, we established a system of nest boxes in southeast Ohio to evaluate the feasibility of using a system of nest boxes to monitor changes in southern flying squirrel (Glaucomys volans) populations. We recorded the time of box placement until first usage and types of ...
Background: Reproductive strategies and evolutionary pressures differ between males and females. This often results in size differences between the sexes, and also in sex-specific seasonal variation in body mass. Seasonal variation in body mass is also affected by other factors, such as weather. Studies on sex-specific body mass patterns may contribute to better understand the mating system of ...
Northern flying squirrels (Glaucomys sabrinus) and red squirrels (Tamiasciurus hudsonicus) in the Black Hills National Forest (BHNF) of South Dakota represent isolated populations. Because data on both species in the region are limited, and because the northern flying squirrel in South Dakota and the Black Hills National Forest has species of concern status, we trapped throughout BHNF to determ...
The order Rodentia is subdivided into two suborders, the Sciurognathi and the Hystricognathi. Within the Sciurognathi, the shortwavesensitive (SWS1) class of visual pigments is ultraviolet-sensitive (UVS) amongst the largely nocturnal murine species, whereas violet-sensitive (VS) pigments are thought to be present in diurnal ground and tree squirrels [1,2]. As the ancestral mammalian pigment is...
