  • Predators help disperse salmon, nutrient on streambanks This article describes the results of a study suggesting another “trophic cascade” mechanism by which predators and salmon interact, enriching the diversity of plant-life in the world’s largest old-growth temperate rainforest: Pacific salmon run helps shape Canada’s ecosystems – BBC News The annual migration sees salmon return to western Canada…

  • The most abundant of all Western pine falls at astounding rate- Every Western pine from the Yukon to New Mexico is suffering high mortality from unusually severe attack by native insects, diseases and direct mortality from drought and heat. Lodgepole pine, which often grows in vast almost monocultural stands, is dying too.  Almost anyone who…
