This study compares the income contribution of forest products with that of farm related activities such as cropping and livestock rearing. Quarterly income data collected over a period of one year are used to compile income profiles for households in two contrasting districts, Mufulira and Kabompo districts in Zambia. Villages in Mufulira are located within easy access to bustling mining towns...

عملکردهای زیستی پروتئین ها به واکنش های شیمیایی آنها با محیط پیرامون و سایر پروتئین ها بستگی دارد. به عبارت دیگر، ساختار سه بعدی و نحوه تاخوردن اجزای پروتئین ها در فضا، چگونگی این تعاملات را تعیین می کند. تشخیص صحیح الگوی تاخوردگی پروتئین با استفاده از اطلاعات استخراج شده از توالی آن، یکی از مسائل پیچیده و بحث برانگیز در زمینه بیوانفورماتیک می باشد. در این پایان نامه، سه روش نوین مبتنی بر الگور...

In Zagros forest ecosystem, spatial variability of soil and vegetation properties are controlled by series of physical and biological parameters including topographical and anthropogenic factors. Distribution patterns of these properties are greatly variable. In the current study, geostatistics and fractal theory were used to assess the spatial variability of tree canopy and soil bulk density i...

We outline an approach combining airborne laser scanning (ALS) and imaging spectroscopy (IS) to quantify and assess patterns of tree density (TD) and forest productivity (FP) in a protected heterogeneous alpine forest in the Swiss National Park (SNP). We use ALS data and a local maxima (LM) approach to predict TD, as well as IS data (Airborne Prism Experiment—APEX) and an empirical model to est...

Non-Timber Forest Products (NTFPs) are vital sources of livelihood for forest-dependent communities across the globe. This study examined NTFPs species (Phyllanthus emblica, P. indofischeri, and Terminalia chebula) population change determined by dependency, disturbances, accessibility in dry tropical forest Malai Mahadeshwara (MM) Hills wildlife sanctuary. The long-term monitoring data were an...

This work uncovers the spectral trajectory of the unique structurally-related information content that is embedded in the angular domain of multi-angular remote sensing data. CHRIS (Compact High Resolution Imaging Spectrometer) mounted onboard the PROBA (Project for On-board Autonomy) spacecraft is capable of sampling terrestrial reflectance anisotropy over the visible/nearinfrared region of th...

Determination of water sources of plant species in a community is critical for understanding the hydrological processes and their importance in ecosystem functions. Such partitioning of plant xylem water into specific sources (i.e. precipitation, groundwater) can be achieved by analysing deuterium isotopic composition (υD) values for source waters. A subalpine dark coniferous forest in southwes...
