Final Report: NASA Grant Number NAGS3439 Monitoring Change in Temperate Coniferous Forest Ecosystems
and Introduction The primary goal of this research was to improve monitoring of temperate forest change using remote sensing. In this context, change includes both clearing of forest due to effects such as fire, logging, or land conversion and forest growth and succession. The Landsat 7 ETM+ proved an extremely valuable research tool in this domain. The Landsat 7 program has generated an extrem...
متن کاملInteractions among Soil Biota in Coniferous Ecosystems
Fogel, R., 1988. Interactions among soil biota in coniferous ecosystems. Agric. Ecosystems Environ., 24: 69-85. The dominance of ectomycorrhizae in most coniferous forest ecosystems profoundly alters the classical concept of the role of exudation and rhizodeposition of cell fragments in the formation of the rhizosphere. In the unaltered, non-ectomycorrhizal rhizosphere the soluble exudates and ...
متن کاملMapping NPP for a Coniferous Forest in Southern Sweden using data from Terra/MODIS
Net primary production (NPP) is modeled for a coniferous forest in southern Sweden for 2001. The model is based on the light-use efficiency concept where NPP is calculated as a product of absorbed photosynthetically active radiation (APAR) and a lightuse efficiency factor (ε). APAR is estimated from the fraction of APAR (FAPAR) multiplied with the daily total amount of incoming PAR. FAPAR is ob...
متن کاملA method for monitoring deposited matter in forest ecosystems.
Systematic and elaborate multidisciplinary research of pedunculate oak and common hornbeam began in the Forest Research Institute in Jastrebarsko in 1991. That led to a development of a method for monitoring deposition in forest ecosystems which is now closely related to the International Co-operative Programme on Assessment and Monitoring of Air Pollution Effects on Forest. Several forest comm...
