Affecting an estimated 1.7 million people annually, traumatic brain injury has been labeled a major public health threat. As the leading cause of death and disability in young people, and the signature wound of the wars in Iraq and Afghanistan, the issue is drawing increased media attention. Analyses begin by...
There will be winners and losers as climate change alters the habitats of polar organisms. For an Adelie penguin (Pygoscelis adeliae) colony on Beaufort Island (Beaufort), part of a cluster of colonies in the southern Ross Sea, we report a recent population increase in response to increased nesting habitat as...
Peppermint, Mentha piperita 'Black Mitcham' was established as a host for tomato
spotted wilt virus-impatiens serotype (TSWV-I). TSWV-I infection of peppermint,
initially observed in a research greenhouse (Corvallis, OR), included stunting and
downward curling of leaves accompanied by bronzing, and occasionally tip necrosis.
Young leaves appeared either symptomless, deformed, or...

Two experiments were conducted to assess the effects of paralysis and oligohydramnios on the development of the rat fetus. Behavior was suppressed in utero by subcutaneous injections of curare or puncture of the amniotic membrane leading to oligohydramnios. In Experiment 1, fetuses were treated with curare, oligohydramnios, both, or a...
Body size, mass and condition can affect an organism’s ability to cope with variation in resource availability or metabolic demand, particularly as juveniles reach independence. It follows that changes to parental provisioning efficiency (size and frequency of meals) through intraspecific competition or environmental conditions that affect prey availability may affect...
Small low-head diversion dams are capable of removing much of the flow of a river, often resulting in increased water temperatures and habitat loss. Warmer temperatures have been shown to accelerate aquatic invertebrate growth and development, and discharge reductions can reduce instream habitat, suggesting that water withdrawals may alter both...
The Utah System of Higher Education (USHE) and the eight public colleges and universities in the system, have depended on the Federal Pell Grant program for more than 40 years to assist students to attend. For some of these institutions, the amount of Pell grant dollars received is as much...
We measured surface soil (0–15 cm) C and N pools and processes inside and outside an area that had been trenched 13 years earlier in an old-growth conifer forest (>450 years) to assess the long-term impacts of reduced root inputs on C and N turnover. Trenching, combined with frequent clipping...
