At the Earth's surface, calcium (Ca) is a critical element at a variety of scales: it is soluble in
natural waters, a biological nutrient, and a major constituent of the dominant mineral sink for …

Forest disturbance regimes are beginning to show evidence of climate-mediated changes,
such as increasing severity of droughts and insect outbreaks. We review the major insects …

Aims The aim of our research was to understand small-scale effects of topography and soil
fertility on tree growth in a forest biodiversity and ecosystem functioning (BEF) experiment in …

Stable isotopes have been commonly used to:(i) identify sources (eg, pollutants to a
stream),(ii) infer processes (eg, heterotrophic nitrification),(iii) estimate rates (eg, soil C …

A study was conducted at two experimental tree plantations in the Pacific Northwest to
assess the roles of bacteria and fungi in nitrogen (N) cycling. Soils from red alder (Alnus …

Reports of large Ca isotope fractionations between trees and soils prompted this study of a
Boreal forest ecosystem near La Ronge, Saskatchewan, to improve understanding of this …

Background: Molecular-level differentiation of neoplastic cells is essential for accurate and
early diagnosis, but effective molecular probes for molecular analysis and profiling of …

Background Although community structure and species richness are known to respond to
nitrogen fertilization dramatically, little is known about the mechanisms underlying specific …

Li, B, Mg and Ca isotopes became of increasing interest during the last decade due to their
potential for better constraining the carbon cycle and nutrient cycling. At the soil-water-plant …

We review the mechanisms of deleterious nitrogen (N) deposition impacts on temperate
forests, with a particular focus on trees and lichens. Elevated anthropogenic N deposition to …
