Monitoring of natural vegetation succession is essential for optimal management of river floodplains in the Netherlands. As the maximum discharge capacity depends on the hydraulic resistance of vegetation, a key biophysical parameter for floodplain monitoring is vegetation biomass. The objective of this study is to investigate the feasibility of mapping above- ground biomass and vegetation structure...
The metabolism and phenology of Amazon rainforests significantly influence global dynamics of climate, carbon and water, but remain poorly understood. In this study we utilized Moderate Resolution Imaging Spectroradiometer (MODIS) terrestrial ecosystem variables to analyze Amazon rainforest dynamics utilizing the satellite products; vegetation indices (VI), leaf area index (LAI), fraction of absorbed...
In this study we investigated the relationships between landscape features such as terrain elevation and slope with two variables that drives forest productivity, soil texture and leaf area index (LAI). The study was carried out at the Tapajos region in Para State, eastern Amazonia. Twenty-four 0.25 ha plots were sampled along a ~150 km north-south transect in October 2002. Soil samples were collected...
Form the macroscopical-ecology point of view, base on remote sensing measure of region ecological capital evaluation's character, consider the possibility and reliability of acquire the data, we developed regional ecological capital assessment index in remote sensing measure. The paper calculate the total ecological capital from nine kind of ecological value. Base on the research achievements of the...
In recent investigations into the response of native grasslands to global environmental changes, rainfall variability has been offered as a key factor for explaining ecosystem structure and function. In particular, changes in the temporal patterns of precipitation were shown to alter critical aspects of the carbon cycle. To understand the impact of rainfall variability in grasslands, an understanding...
Natural Resources Canada, Parks Canada Agency and the University of Ottawa are developing standardized approaches for monitoring landscape change within and surrounding Canada's National Parks using Earth observation. This paper focuses on remote sensing methodologies developed at the CCRS for three types of ecological indicators: Landscape Pattern, Succession & Retrogression, and Net Primary...
Spectroscopy has existed for more than three centuries now. Nonetheless, significant scientific advances have been achieved. We discuss the history of spectroscopy in relation to emerging technologies and applications. Advanced focal plane arrays, optical design, and intelligent on-board logic are prime prospective technologies. Scalable approaches in pre-processing of imaging spectrometer data will...
