A survey of Oregon sheep producers conducted as part of this research, indicated that lambing losses by sheepgrowers in winter rainfall areas of Oregon currently average 16 percent. The majority of the lambs born in these areas are born in pastures without the benefit of shelter. The utilization of portable...
In 1959 the British Ornithological journal, The Ibis, published a centenary commemorative volume on the history of ornithology in Britain. Over the previous few decades, the contributors to this volume had helped focus the attention of ornithologists on the methods, priorities, and problems of modem biology, specifically the theory ofevolution...

for gonadotropic and thyrotropic hormone content by injecting
a suspension of the macerated gland in saline into...
Both travel times and amplitudes of large offset refracted and reflected arrivals
observed during GLIMPCE (Great Lakes International Multidisciplinary Program on

ray tracing techniques. Forward modeling was used to iteratively refine an
initial velocity model that was...
