Does Locomotor Ability Influence Flight Initiation Distance in YellowBellied Marmots?
Flight initiation distance (FID) is the distance between a potential threat and the point at which a potential prey flees. Animals may modify their FID to compensate for increased risk generated by external/extrinsic factors such as habitat type, visibility, group size, time of year, predatorapproach velocity, and distance to burrow, as well as internal/intrinsic factors such as physical condit...
متن کاملIsland tameness: living on islands reduces flight initiation distance.
One of Darwin's most widely known conjectures is that prey are tame on remote islands, where mammalian predators are absent. Many species appear to permit close approach on such islands, but no comparative studies have demonstrated reduced wariness quantified as flight initiation distance (FID; i.e. predator-prey distance when the prey begins to flee) in comparison with mainland relatives. We u...
متن کاملColor Change, Phenotypic Plasticity, and Camouflage
Martin Stevens is Associate Professor of Sensory and Evolutionary Ecology at the University of Exeter. He did his PhD at Bristol University on bird vision and animal camouflage, and then undertook several fellowships at Cambridge University before moving to Exeter in 2013. His work has focussed on animal coloration, vision, and methods to quantify visual signals, especially image analyses. This...
متن کاملThe influence of distance to refuge on flight initiation distance in the gray squirrel (Sciurus carolinensis)
DILL, L. M., and HOUTMAN, R. 1989. The influence of distance to refuge on flight initiation distance in the gray squirrel (Sciurus carolinensis). Can. J. Zool . 67: 233 235. Gray squirrels (Sciurus carolinensis) typically run to the nearest tree to escape from predators they encounter while foraging on the ground. As the risk of capture increases with distance from the refuge tree, squirrels fe...
متن کاملDoes intruder group size and orientation affect flight initiation distance in birds?
Does intruder group size and orientation affect flight initiation distance in birds?— Wildlife managers use flight initiation distance (FID), the distance animals flee an approaching predator, to determine set back distances to minimize human impacts on wildlife. FID is typically estimated by a single person; this study examined the effects of intruder number and orientation on FID. Three diffe...
