Causes and rates of mortality of swift foxes in western Kansas
Article Abstract:
The magnitude and causes of mortality of swift fox populations in two study areas in western Kansas were examined using radiotelemetry techniques. Mortality rates were greater in juvenile than in adult foxes. No differences were seen between study areas in mortality rates for adults or juveniles. Predation by coyotes was the major cause of mortality for the foxes in both study areas. Vehicle collision was an important mortality factor for juveniles in the cropland study area. No death was attributed to disease or starvation.

Dispersal patterns of red foxes relative to population density
Article Abstract:
The study of the dispersal patterns of tagged red foxes (Vulpes vulpes) in North Dakota reveals that dispersal is common red foxes and that fox density has no affect on dispersal distance. Mean recovery distance is less for females than for males and becomes greater with the increase in age. Males and females disperse in different directions, and straight-line dispersal distances are not influenced by population density. The dispersal behavior of the foxes helps to increase the fox population when needed.

Differential effects of coyotes and red foxes on duck nest success
Article Abstract:
Duck populations in the Prairie Pothole region of North American have been hampered by high predation rates primarily by the red fox. However, the red fox population is depresssed by coyotes. Studies have shown that duck nest success rates are higher in regions where higher concentrations of coyotes exist. It is suggested that cultivating higher coyote populations will significantly increase duck nest success.
