Ecological-niche Factor Analysis: How to Compute Habitat-suitability Maps without Absence Data?
We propose a multivariate approach to the study of geographic species distribution which does not require absence data. Building on Hutchinson’s concept of the ecological niche, this factor analysis compares, in the multidimensional space of ecological variables, the distribution of the localities where the focal species was observed to a reference set describing the whole study area. The first...
متن کاملmodelling of persian gazelle (gazella subgutturosa subgutturosa) habitat suitability using ecological niche factor analysis method in gharaviz no hunting area
gharaviz no hunting area is known as one of the most important habitats of persian gazelle (gazella subgutturosa subgutturosa) in west zagros mountains. developing models to predict the distribution of wildlife is suitable tool for conservation and management. in this approach, the boundary of the study area was considered the distribution area and then were compared with actual region. field d...
متن کاملHabitat suitability modelling and niche theory
1. The concept of the ecological niche relates a set of environmental variables to the fitness of species, while habitat suitability models (HSMs) relate environmental variables to the likelihood of occurrence of the species. In spite of this relationship, the concepts are weakly linked in the literature, and there is a strong need for better integration. 2. We selectively reviewed the literatu...
متن کاملGlobal Habitat Suitability and Ecological Niche Separation in the Phylum Placozoa
The enigmatic placozoans, which hold a key position in the metazoan Tree of Life, have attracted substantial attention in many areas of biological and biomedical research. While placozoans have become an emerging model system, their ecology and particularly biogeography remain widely unknown. In this study, we use modelling approaches to explore habitat preferences, and distribution pattern of ...
متن کاملraccoon (procyon lotor) non- native and invasive species habitat suitability modeling by ecological niche factor analysis method in lavandevil wildlife refuge
raccoon is a native species to north and central america. at present, it is an invasive species in many countries such as japan, germany, russia and iran. raccoon was observed for the first time in gilan province in iran in 1991. this research was employed ecological niche factor analysis (enfa) method to model habitat selection of raccoon in lavandevil wildlife refuge. the results showed that ...
