The current rate of global biodiversity loss and extinctions is unparalleled and a major concern. Freshwater organisms are facing particularly rapid rates of biodiversity loss. Amphibians, which require an aquatic environment for part of their life cycle, are one of the most vulnerable vertebrate groups. Amphibians are experiencing population declines,...
We investigated the effect of pyridoxine
supplementation on the utilization of protein in a low-protein,
plant-based diet in four subjects (2 men and
2 women), aged 21 to 38 years. Following two days of a
negligible protein diet, this 34 day study was divided into
three dietary periods: the subjects...
Microorganisms can be a valuable tool in assessing the toxicity of heavy metals. The soil respiration rate is a commonly explored endpoint. I utilized a fully automated respirometer incorporating an infrared gas analyzer (IRGA) and developed a method for measuring the effect of Zn on soil microbial populations. Zinc, in...
Glacial isostatic adjustment (GIA) alters the amplitude and timing of ‘glacioeustatic’ sea level maxima and minima around the globe. No study has examined the intrinsic distance that one can correlate marine stratigraphic records of glacial–interglacial sedimentation across continental shelves subject to varying amounts of GIA. Here, we seek to model...
Gram positive cocci isolated from Oregon wines
were characterized and their relative malate fermentation
abilities compared. They were heterofermentative,
catalase negative, and facultatively anaerobic. Glucose,
fructose, cellobiose, maltose, ribose, trehalose, salicin
and esculin were fermented by all strains. Arabinose was
fermented weakly but lactose, raffinose, sucrose, xylose,
rhamnose, mannose and...
