ABSTRACT: Resource-matching, or organismal co-location with specific resources, is a widely observed theoretical phenomena that underpins many efforts to model species occurrence, abundance, or movement. Many resource-matching analyses assume that patterns in occurrence at a location at a specific time relate to optimal behavior at that location, but this is rarely evaluated. We assessed variability in White-tailed deer behaviors (foraging, resting, vigilance) observed using remote cameras across Wisconsin in order to determine the spatial and temporal scales at which these behaviors most strongly varied, and whether deer foraging behavior was linked to spatial and temporal differences in vegetation productivity derived from satellite-based indices. Deer practiced behavioral-resource matching in that they were more likely to forage in times and places where vegetation productivity was greater. Other behaviors were more strongly linked to alternative factors: for example, resting behavior exhibited diel variability but was less likely at sites predators used. Our results suggest that animals may alter and match their behaviors to their surrounding environs, but that the spatiotemporal scale that influences specific behaviors is highly variable.
