Spatial Modeling of Rangeland Potential Vegetation Environments

Degradation of Non-Photosynthetic Vegetation in a Semi-Arid Rangeland

Land degradation in drylands is the process in which undesirable conditions emerge due to human and natural causes. Despite the particularly deleterious effects of degradation, and it’s potentially irreversible nature, regional assessments have provided conflicting extents, rates, and severities of degradation, both globally and regionally. Current monitoring of degradation relies upon the dete...

Effect of image spatial and spectral characteristics on mapping semi-arid rangeland vegetation using multiple endmember spectral mixture analysis (MESMA)

Fast, spatial domain potential field modeling

In this contribution we propose an alternative method to the traditional spatial domain technique of prism integration in potential field modeling. The advantages and disadvantages of prism integration as compared to e.g. Fourier methods or wavelet methods are well known. Our aim is to improve the main disadvantages of the space domain methods in order to make them an attractive alternative to ...

Investigation of Changes in Rangeland Vegetation Regarding Different Slopes, Elevation and Geographical Aspects (Case Study: Yazi Rangeland, Noor County, Iran)

In many studies, topographic factors have been considered as an important factor in establishing the vegetation in different ecosystems. So, it affects vegetation composition and diversity by influencing soil moisture, fertility and soil depth. The aim of this research was to investigate the effects of slope, elevation and geographical aspects on species growth, forage production and vegetation...

Acclimatization Potential of Dracaena Sanderiana ‘Victory’ to Contrasting Light Environments

The present study was conducted to ascertain the ability of Dracaena sanderiana ‘Victory’, a foliage plant species of commercial importance in both domestic and international markets, to thrive under contrasting light environments. The experiment was carried out inside a semi-open greenhouse in Peradeniya, Sri Lanka. Same sized and same aged, ready-to-ship export quality plugs of Dracaena sande...
