Accurately measuring productive capacity in streams is challenging, and field methods have generally focused on the limiting role of physical habitat attributes (e.g. channel gradient, depth, velocity, substrate). Because drift-foraging models uniquely integrate the effects of both physical habitat (velocity and depth) and prey abundance (invertebrate… (More)
Glioblastoma multiforme of the cerebellum is rare and comprises a small fraction of all glioblastomas. Eight-five cases have been reported in the literature to date. A 75 year old man is reported with a left cerebellar glioblastoma multiforme. The pathogenesis, course, treatment and prognosis are reviewed.
Population viability analysis (PVA) is an effective framework for modeling species- and habitat-recovery efforts, but uncertainty in parameter estimates and model structure can lead to unreliable predictions. Integrating complex and often uncertain information into spatial PVA models requires that comprehensive sensitivity analyses be applied to explore the… (More)
The effect of the oral administration of 0.150 mg/m2 clonidine on the plasma level of human growth hormone (hGH) was studied in 53 adults (25 males and 28 females) aged from 28 to 68 years, of which 15 were healthy volunteers and 38 were hypertensive. Both the normal and hypertensive subjects of both sexes showed an age-related responsiveness of hGH to… (More)
