In northern California, USA, western Burrowing Owls (Athene cunicularia) use burrows in active California ground squirrel (Otospermophilus beecheyi) colonies for nesting and protection. Ground squirrels have wel
Ground squirrels become infected with plague following hibernation and again when reoccupying colonial burrows (Davis, 1999). B Viral Infections Ground squirrels infected with ground squirrel hepatitis virus (GSHV) develop a mild, nonprogressive persistent hepatitis (Cullen and Marion, 1996). ...

Meanwhile, the assault on Northern California Indian communities continues. In February, 1996, the Elem colony Burrows family took their dehydrated 11-month-old son Cody for the third time to Adventist Health Redbud Community Hospital in Clear Lake. There, Dr. Wolfgang Schug decided, either becaus...
Place one unpeeled banana and a peeled banana on the ground one meter apart from each other. 3. Predict which piece of fruit ants will be more attracted to. 4. Leave both bananas on the ground. Check to see if there are any ants on them. Check back after one hour; after two hours...
The mating system of the California ground squirrel, Spermophilus beecheyi , was examined to determine the incidence of multiple paternity of litters and the circumstances under which it occurs. The population studied has a promiscuous mating system. All receptive females solicited and mated with ...
The squirrels reacted by running to boulders or burrows and freezing. As time progressed following playbacks, freezing declined and squirrels resumed feeding, locomotion and grooming. With increasing numbers of whistles, squirrels were more likely to run and less likely to mount a boulder. With ...
Using burrows as an indirect measure of mammal presence, we found that the presence of trees had a negative effect on the occurrence and abundance of ground squirrels on levees, and on the location of their burrowing activities on the levee slope, potentially because visual occlusion caused by ...
i. The antipredator strategy of snake harassment by California ground squirrels is sensitive to risk, exhibiting attenuation where risk is higher. 2. Olfaction is likely to be even more important during squirrel-snake encounters in the dark, especially in burrows. 3. The ability to recognize ...
Here, I demonstrate the integration of the two disciplines by describing my studies on California ground squirrel (Spermophilus beecheyi) antipredator behavior in the presence of electricity-generating wind turbines.; I identify a previously unaddressed impact of wind turbines, the high amplitude noise ...
