[ 1 ] - Required Growing Degree-Days (GDDs) for each Phenological Stage of Fritillaria imperialis
Studying plant phenology is very important to regulate the rangeland utilization. Plant phenology can be determined by Growing Degree Days (GDDs). Since temperature varies yearly, the phenological stages may consequently differ yearly. Determining the base temperature is one of the key steps in the calculation of GDDs. The aim of this study was to calculate the required GDDs for each phenologic...
[ 2 ] - Comparing the accuracy of pixel and object-based classification methods in mapping vegetation types (Case study: Marjan Boroujen)
This article has no abstract.
[ 3 ] - Development of a Google Earth Image's Visual Interpretation Protocol to Determine Plant Ecological Units of the Semi-Steppe Regions
Extended Abstract Background and objectives: Google Earth images are a valuable resource for understanding and studying the natural area's ecology due to their high spatial resolution. Considering that these images have been available for many years, in our country, these valuable data have not been used enough, especially in order to study vegetation and optimal natural areas management. So, ...
[ 4 ] - Potential geographic distribution of Prangos ferulacea (L.) Lindl. in Chaharmahal va Bakhtiari province under climate change scenarios
Prangos ferulacea (L.) Lindl is a perennial plant that besides fodder and medicinal values the plant can help to control soil erosion. There is little knowledge about the effect of climate change on the Prangos genus especially P. ferulacea. In this study, we used ensemble modeling based on five species distribution models to predict the potential effects of climate change on the future geograp...
[ 5 ] - Evaluation of the ability of different algorithms and visual interpretation of Google Earth images in the separation and classification of plant ecological units
Background and objectives: Satellite images and remote sensing technology are recognized as efficient and modern tools for extracting information related to earth sciences, which make it possible to evaluate and monitor ecosystems at a lower cost than field methods. One of the most important methods of extracting information from satellite data is various image classification techniques. The pr...
