Habitat selection of honey badgers: are they at the risk of an ecological trap?
Human-induced environmental changes have dramatically changed habitats worldwide, decreasing the quantity and quality of habitats for wildlife and putting wild populations at risk. In the current study habitat suitability of the honey badger (Mellivora capensis) across its distribution range in Southern Iran was investigated. We combined presence-only field data with environmental and anthropogenic variables, generating an ensemble model of habitat suitability based on four species distributionmodels. The contribution scores of anthropogenic variables (human footprint index and village density) in the model were noticeable, indicated that honey badgers do not avoid humanmodified areas. The ensemble model further revealed large areas of low quality of natural habitats across the study area. Land use changes may have led honey badgers to settle in poor-quality habitats, where their fitness may be lower than in other available habitats. Therefore, there is a possible risk of an ecological trap due to the lack of protected high-quality habitats. Further research on honey badger fitness, in human-modified areas, is required to evaluate the hypothesis of ecological trap.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
