Determining Differences In The Spatial Distribution Of Forest Structure On The Kaibab Plateau: Implications For Forest Management And The Northern Goshawk, Ryan S. Miller
Other Publications in Wildlife Management
The Kaibab Plateau, in North Central Arizona, has undergone extensive change in the last 100 years due to land management practices such as logging, road building, and fire suppression. The northern goshawk (Accipiter gentilis) has been a center of controversy, due to the potential effects of silvicultural practices on goshawk breeding habitat (Reynolds-1983, Bloom et al 1986, Kennedy 1989, Crocker-Bedford 1990). Current and past research efforts on the Kaibab Plateau have mapped Goshawk nesting territories and temporal change in nesting behavior and success. However, these research efforts have not determined how long-term spatial changes in land-use activities that have influenced …

Electric Chick Brooding Studies, F. D. Yung, F. E. Mussehl
Nebraska Agricultural Experiment Station: Historical Circulars
Perhaps one of the most valuable lessons to be learned from a study of chick brooding is that good results can often be obtained in more ways than one. In carrying on work with electric brooders at the Nebraska Agricultural Experiment Station, special attention has been given to such factors as insulation and to other details of design which effect economy of operation and ease of construction. Low cost rather than "cheapness" has been the ideal. The work has been cooperative between the Agricultural Engineering Department and the Poultry Husbandry Department of the University of Nebraska.

Why Some Hens Lay More Eggs Than Others, H. E. Alder
Why Some Hens Lay More Eggs Than Others, H. E. Alder
Nebraska Agricultural Experiment Station: Historical Circulars
The 1929 report of the Storrs Egg Laying Contest, which has been conducted at Storrs, Connecticut, twenty-one years, shows that the best pen of ten hens entered laid 2,802 eggs, and the poorest pen laid 829 eggs. In the best pen the average egg production per hen was 280, 2 eggs as compared with 82.9 eggs per bird in the poorest pen. Why did the one pen lay so many eggs, and the other so few? This prompts us to try to find out what factors are responsible for the number of eggs a hen lays in the course of …
