Habitat modelling is a tool for regionalisation of biotic information by predicting the spatially explicit distribution of species on the basis of environmental properties. Since this recent method has a high relevance in questions of nature conservation and ecological research, there is a need to teach it in environmental studies. The multimedia GIMOLUS-environment provides all elements necess...
Habitat suitability modeling for wild goat (Capra aegagrus) in a mountainous arid area, central Iran
Wild goat (Capra aegagrus) is one of the most prominent mountain mammals dispersed in many habitats in Iran. However, few studies on the relationship between this species and its habitat have been conducted. This species is recognized as one of the main food source for highly endangered species such as cheetah and leopard. In this study which lasted from fall 2009 through summer 2011, seasona...
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...
Figure 1: Principle of habitat modelling: sampling of species distribution data (here: presence-absence data) and selected predictor variables; estimating an empirical, predictive model (in this case: by logistic regression a generalised linear model for binary response variables, other, more flexible approaches are generalised additive models, classification and regression trees, artificial ne...
مدلسازی مطلوبیت زیستگاه خرس قهوهای (Ursus arctos) در منطقه حفاظت شده شیمبار، استان خوزستان
Status determination of wildlife habitats is very important in conservation programs and management of wildlife. So, in this study Ursus arctos habitat suitability was modeled using maximum entropy algorithm (MaxEnt) in Shimbar protected area. In order to model the habitat suitability, after investigating and resolving the spatial autocorrelation of occurrence records, spatially independent loc...

Pine needles have been widely used in the development of anti-hypertensive and anti-hyperlipidemic agents and health food. However, the widespread distribution of this tree poses great obstacles to the quality control and efficacy evaluation. To facilitate the effective and rational exploitation of Masson's pine (Pinus massoniana Lamb), as well as ensure effective development of Masson's pine n...
