Cable yarding systems (also sometimes known as skyline yarding systems) are a versatile means for transporting materials in mountainous terrain in situations that do not allow for conventional harvesting methods such as ground skidding or shovel-logging. Adequate ground anchors are necessary for the safe operation of cable yarding systems. Anchored...

Forests play a critical role sequestering atmospheric carbon dioxide, partially offsetting greenhouse gas emissions, and thereby mitigating climate change. Forest management, natural disturbances, and the fate of carbon in wood products strongly influence carbon sequestration and emissions in the forest sector. Government policies, carbon offset and trading programs, and sustainable...

Abstract
Background
Climate-driven changes in biotic interactions can profoundly alter ecological
communities, particularly when they impact foundation species. In marine systems,
changes in herbivory and the consequent loss of dominant habitat forming species can
result in dramatic community phase shifts, such as from coral to macroalgal
dominance when tropical fish herbivory decreases,...
