Modeling Species Distribution Using Niche-Based Proxies Derived from Composite Bioclimatic Variables and MODIS NDVI
Vegetation mapping based on niche theory has proven useful in understanding the rules governing species assembly at various spatial scales. Remote-sensing derived distribution maps depicting occurrences of target species are frequently based on biophysical and biochemical properties of species. However, environmental conditions, such as climatic variables, also affect spectral signals simultane...

متن کاملTree Species Classification Using Ers Sar and Modis Ndvi Images
A set of ERS SAR and optical MODIS-images were classified to land cover and tree species classes. Different methods for pixel and decision based data fusion were tested. Classifications of featuresets were carried out using Bayes rule for minimum error. The results were not very successful, the classification accuracies of land cover classes varied from 43% to 75%, depending on the used feature...
متن کاملPredicting the Climatic Ecological Niche of Artemisia aucheri Boiss in Central Iran using Species Distribution Modeling
Changes in the geographical distribution of plants are one of the major impacts of the climate change. This study was aimed to predict the potential changes in the distribution of Artemisia aucheri Boiss in Isfahan rangelands. Therefore, six bioclimatic variables and two physiographic variables were used under the Generalized Linear Model (GLM), Flexible Denotative Analysis (FDA), Surface Range...
متن کاملNiche Variability and Its Consequences for Species Distribution Modeling
When species distribution models (SDMs) are used to predict how a species will respond to environmental change, an important assumption is that the environmental niche of the species is conserved over evolutionary time-scales. Empirical studies conducted at ecological time-scales, however, demonstrate that the niche of some species can vary in response to environmental change. We use habitat an...
