A fuzzy approach to ecological modelling and data analysis
نویسندگان
چکیده
Ecologists collect and evaluate data from all possible data sources, sources of objective (mostly quantitative) data, like measurements and simulation results and sources of subjective (often only imprecise qualitative) information, like subjective estimations obtained from an expert. Not all ecological parameters are measurable, for example, the number and biomass of fi sh in a particular lake. Besides the usual problem of searching for effective methods for data analysis and modelling, there are some additional problems with handling ecological data. These problems result from some characteristic properties of environmental data, namely:

Fuzzy logic approach to data analysis and ecological modelling
The paper focuses on two large application areas of the Fuzzy Set Theory in ecological research, namely data analysis (in particular fuzzy cluster analysis and fuzzy kriging) and ecological modelling. Environmental data or classes of ecological objects can be defined as fuzzy sets with not sharply defined boundaries, that reflects better the continuous character of nature. Fuzzy sets are used t...
متن کاملComparing Discriminant Analysis, Ecological Niche Factor Analysis and Logistic Regression Methods for Geographic Distribution Modelling of Eurotia ceratoides (L.) C. A. Mey
Eurotia ceratoides (L.) C. A. Mey is an important plant species in semi-arid landsin Iran. New approaches are required to determine the distribution of this plant species. Forthis reason, geographical distributions of Eurotia ceratoides were assessed using threedifferent models including: Multiple Discriminant Analysis (MDA), Ecological Niche FactorAnalysis (ENFA) and Logistic Regression (LR). ...
متن کاملProviding Protection Solutions of Anzali Wetlands With the Modern Watershed Approach
The purpose of the modern watershed study is to use a regional pilot to select an erosion sub-basin and restore it to preserve the downstream wetland. In this research, Alanza watershed, located in the upstream reaches of Anzali wetland, has been selected as a sub-watershed (pilot) with the aim of investigating the effect of mechanical, biological and biomechanical operations on modern watershe...
متن کاملA Novel Type-2 Adaptive Neuro Fuzzy Inference System Classifier for Modelling Uncertainty in Prediction of Air Pollution Disaster (RESEARCH NOTE)
Type-2 fuzzy set theory is one of the most powerful tools for dealing with the uncertainty and imperfection in dynamic and complex environments. The applications of type-2 fuzzy sets and soft computing methods are rapidly emerging in the ecological fields such as air pollution and weather prediction. The air pollution problem is a major public health problem in many cities of the world. Predict...
متن کاملAN APPLICATION OF FUZZY NUMBERS TO THE ASSESSMENT OF MATHEMATICAL MODELLING SKILLS
In this paper we use the Triangular and Trapezoidal Fuzzy Numbers as tools for assessing student Mathematical Modelling (MM) skills. Fuzzy Numbers play a fundamental role in fuzzy mathematics analogous to the role played by the ordinary numbers in classical mathematics, On the other hand, MM appears today as a dynamic tool for teaching and learning mathematics, because it connects mathematics w...
