Increased nitrogen leaching following soil freezing is due to decreased root uptake in a northern hardwood forest.
The depth and duration of snow pack is declining in the northeastern United States as a result of warming air temperatures. Since snow insulates soil, a decreased snow pack can increase the frequency of soil freezing, which has been shown to have important biogeochemical implications. One of the most notable effects of soil freezing is increased inorganic nitrogen losses from soil during the fo...
متن کاملDoes soil respiration decline following bark beetle induced forest mortality? Evidence from a lodgepole pine forest
Lodgepole pine (Pinus contorta var. latifolia) forests across western North America have been undergoing a major mortality event owing to a mountain pine beetle (Dendroctonus ponderosae) infestation. We studied biotic and abiotic drivers of growing season soil respiration in four mature stands experiencing different levels of mortality between 2008 and 2012 in southeastern Wyoming, USA. Bark be...
متن کاملHistory of Tree Growth Declines Recorded in Old Trees at Two Sacred Sites in Northern China
Old forests are an important component in sacred sites, yet they are at risk of growth decline from ongoing global warming and increased human activities. Growth decline, characterized by chronic loss of tree vigor, is not a recent phenomenon. Knowledge of past occurrence of declines is useful for preparing conservation plans because it helps understand if present day forests are outside the na...
متن کاملReduced snow cover alters root-microbe interactions and decreases nitrification rates in a northern hardwood forest.
Snow cover is projected to decline during the next century in many ecosystems that currently experience a seasonal snowpack. Because snow insulates soils from frigid winter air temperatures, soils are expected to become colder and experience more winter soil freeze-thaw cycles as snow cover continues to decline. Tree roots are adversely affected by snowpack reduction, but whether loss of snow w...
متن کاملRestoring Soil Calcium Reverses Forest Decline
Forest decline in the northeastern United States has been linked to the effects of acid deposition on soil nutrients. To test this link, we added a calcium silicate mineral to a paired watershed at the Hubbard Brook Experimental Forest, New Hampshire, in an amount designed to gradually replace the estimated amount of calcium lost as a result of human activity in the 20th Century (primarily beca...
