Spatial variation in transferrin allele frequencies among herds of feral donkeys in Death Valley National Monument, California
Serum proteins were studied to clarify interrelationships of seemingly disjunct herds of feral donkeys (Equus asinus) in the mountains of Death Valley National Monument, California. Sera of 162 donkeys from five localities in the Panamint Mountains were examined by starch-gel electrophoresis to assess polymorphic variation in transferrins. Four homozygous and six heterozygous transferrin phenotype

Wilderness permit compliance and validity
In Yosemite National Park, 92 percent of the parties using back country areas had permits. Parties without permits were smaller in size and stayed for shorter periods of time. For all parties with permits, 62 percent made changes to their trips. Parties changing their trips in both time and space accounted for 27 percent of the total, while 14 percent made temporal changes only, and 21 percent mad

Travel time variation on backcountry trails
Numerous interrelated factors influence the travel times of hikers and riders on backcountry trails. This study sought to quantify those factors which were thought to be most important in affecting trail speeds. The travel times of 897 backpacking parties, 634 day hiking parties, and 111 riding parties were obtained from gentle (0.75%), moderate (5.0%), and steep (12.5%) trail segments one mile in
