Spring And Summer Habitat Preferences Of Blue Grouse On The Bear River Range, Utah, Robert M. Maestro May 1971

Spring And Summer Habitat Preferences Of Blue Grouse On The Bear River Range, Utah, Robert M. Maestro

All Graduate Theses and Dissertations

A study of the spring and summer habitat preferences of blue grouse was conducted on the Bear River Range in northern Utah. The main objective was to determine the important factors associated with habitat selection by blue grouse during the breeding season.

One hundred and two sampling areas, delimited by similarities in vegetation and topography, were thoroughly searched with a dog for blue grouse. Fifty-four bio logical and physical variables were measured for each sampling area.

Chi-square tests performed on all variables showed 11 of the 54 variables to be significant at an alpha of 0.20. These 11 variables ...


Ecology Of Badgers In Curlew Valley, Utah And Idaho With Emphasis On Movement And Activity Patterns, Frederick G. Lindzey May 1971

Ecology Of Badgers In Curlew Valley, Utah And Idaho With Emphasis On Movement And Activity Patterns, Frederick G. Lindzey

All Graduate Theses and Dissertations

Between March, 1969 and July, 1970, 16 badgers (Taxidea taxus) were caught and fitted with radio transmitters in the southern part of Curlew Valley. The animals were followed telemetrically; seven animals contributed sufficient data from which home-range, movement and activity patterns could be discerned. The aver age annual home-range size of five females was 664 acres (± s.d. 99 .5 acres). Female home-range sizes were approximately the same within crested wheat-grass (Agropyron aristatum) and sagebrush (Artemisia tridentata) vegetation types, with greater distances traveled each night by females in the crested wheat-grass. Both home-range size and total movement were less during ...
