Modeling Ecosystem Processes and Peat Accumulation in Boreal Peatlands
Northern peatlands have accumulated up to about 450 Gt of carbon, mostly during the Holocene (the last 12,000 years) after the last glaciation (Gorham 1991; Clymo et al. 1998). Although northern peatlands have a relatively low average net accumulation rate (e.g., 19.4 g C m–2 year–1 in western interior Canada; Vitt et al. 2000), their extent, high-latitude location, and the large size of their ...
متن کاملForest Roads Mapped Using LiDAR in Steep Forested Terrain
LiDAR-derived digital elevation models can reveal road networks located beneath dense forest canopy. This study tests the accuracy of forest road characteristics mapped using LiDAR in the Santa Cruz Mountains, CA. The position, gradient, and total length of a forest haul road were accurately extracted using a 1 m DEM. In comparison to a field-surveyed centerline, the LiDAR-derived road exhibite...
متن کاملEvaluating the Impact of Road Longitudinal Slope Angle in Forest Roads (Main Access and Main Roads) on Runoff and Soil Loss. (Case Study: Gardeshi District, Mazandaran)
Extended abstract 1- Introduction Forest is a sustainable ecosystem with a high balance, and is characterized by non-eroded soils and sediment-free water. Forest roads serve as the largest construction activities and a component added to the forests which are required for the accessibility to forests and forest resources, logging, transportation, conservation, tourism, etc. However, these...
متن کاملImpact of Cypermethrin on enzyme activities in the freshwater fish Cirrhinus mrigala (Hamilton)
Freshwater fish Cirrhinus mrigala were exposed to lethal concentration (5 mg/L) for 1,2,3,4 days and sublethal concentration (1 mg/L) for 1,7,14,21 days of cypermethrin to examine the enzymes activity, in functionally three different tissues namely, gill, liver and muscle. Activities of Aspartate aminotransferase (AAT), Alanine aminotransferase (AlAT) and Glutamate dehydrogenase (GDH) increased...
