This study was designed to determine whether
dietary protein is a nutritional factor influencing the
bioavailability of dietary fluoride. To accomplish
this, a factorial experiment was conducted with
weanling rats fed a purified diet to determine the
influence of dietary protein type (casein or
lactalbumin) and level (12% or 36%)...
Abstract: Relationships between tree traits and tree value for lumber production were investigated. For the purposes of
estimating relative economic weights for use in multitrait selection in coastal Douglas-fir (Pseudotsuga menziesii
(Mirb.) Franco var. menziesii), tree height, diameter at breast height, and branch diameter were measured on 164 trees
(ages...
Spider wasps had long been proposed to originate in the mid-Cretaceous based on the Burmese amber fossil Bryopompilus interfector Engel and Grimaldi, 2006. We performed a morphological examination of this fossil and determined it does not belong to Pompilidae or any other described hymenopteran family. Instead, we place it in...
The Bering Sea responds rapidly to atmospheric perturbations and over the past several decades has experienced extreme variability in both its physical and biological characteristics. These changes can
impact organisms that inhabit the region, particularly marine fishes, as normal current patterns to which
reproductive habits are tuned can be disrupted,...
Wildfires are keystone components of natural disturbance regimes that maintain ecosystem structure and functions, such as the hydrological cycle, in many parts of the world. Consequently, critical surface freshwater resources can be exposed to post-fire effects disrupting their quantity, quality and regularity. Although well studied at the local scale, the...

We hypothesized that changes in southeastern Bering Sea foraging conditions for black-legged kittiwakes (Rissa tridactyla)
have caused shifts in habitat use with direct implications for population trends. To test this, we compared at-sea
distribution, breeding performance, and nutritional stress of kittiwakes in three years (2008–2010) at two sites in the...
