Widespread abandonment of agricultural land has occurred in northeastern North America over the past two centuries. Soil carbon often increases as sites naturally regenerate towards perennial grasslands or forests. ...

Growing interest in biomass crops for energy production has focused attention on Panicum virgatum L. (switchgrass) as a promising perennial feedstock native to much of North America. Switchgrass may be processed into ...

Virtually all multicellular organisms rely on a highly conserved innate immune system for defense against foreign microorganisms. Innate immunity consists primarily of a humeral response that culminates in the expression ...

Forty-five lakes in Killarney Provincial Park and the surrounding area in south-central Ontario, Canada, were sampled for crustacean zooplankton and water chemistry in the summer of 2005. For each of the lakes, we had ...

The mechanisms of plant response to nutrient limitation and utilisation are of great interest for agricultural purposes. Phosphate is a non-renewable resource and is one of the most important nutrients required for plant ...

The retinoid X receptor (RXR) participates in a multitude of nuclear receptor signaling pathways and is induced by its highly sought-after cognate ligand, 9-cis-retinoic acid (9-cis-RA). In flies and moths, molting is ...

Studying the winter ecology of freshwater fishes has been a focus of much past and present research. Because of obvious constraints with studying fish in situ during the winter, few studies have made links between laboratory ...

Lake Challa is a 5 km2, 97m deep freshwater crater lake located at 880m elevation on the southeast slope of Mount Kilimanjaro (Kenya-Tanzania). Information gained from a preliminary limnological survey of Lake Challa, ...

The influence of body size on metabolic rate, muscle enzyme activities, and the underlying patterns of mRNA for these enzymes were explored in an effort to explain the genetic basis of allometric variation in metabolic ...

Hsp22 has been implicated in stress tolerance and longevity in various organisms though its role in Drosophila melanogaster larval thermal tolerance has not yet been investigated. I undertook this project to determine if ...
