Natal dispersal is an important driver of population and colonization dynamics, yet factors that
affect timing and distance of post-fledging movements are poorly understood. We studied post-fledging movements
of 34 (12 male and 22 female) juvenile Burrowing Owls (Athene cunicularia) between June 2002 and April
2003, in a nonmigratory population...
Reproductive strategies of birds are shaped by patterns of food supply, yet empirical evidence of the consequences and mechanisms of food limitation on reproductive performance is inconsistent, probably due to variable responses from species of differing life-history strategies. We tested the hypothesis that food supplementation would increase reproductive rates of...
The acorn woodpecker is among the most common primary cavity nesting bird of the Oregon white oak woodlands. In most of
their range, acorn woodpeckers are dependent on granaries for acorn storage, yet little is known about their selection of granary
sites. We compared habitat characteristics within 12 m of...
An experimental investigation has been performed to determine the
forced convection heat transfer due to three-dimensional air flow over
a flat plate as a function of angle of attack and free stream velocity.
The experimental method employed a transient thermal technique and
placed the convecting surface next to the exhaust...
The U.S. Department of Energy (DOE) Order 458.1 states that the compliance with the DOE annual dose limit of 1 mSv (100 mrem) to a member of the public may be demonstrated by calculating dose to the maximally exposed individual (MEI) or to a representative person. Historically, the MEI concept...
Aquatic animals are exposed to a variety of natural and
anthropogenic xenobiotics. Biotransformation of xenobiotics was
examined in three aquatic animals: a primitive mollusc (chiton);
a shellfish which is an important human food source (oyster);
and, a lower vertebrate model for toxicological studies (rainbow
trout). Since digestive glands of Cryntochiton...
