Technical Abstract: Because of a lack of comprehensive surveys, the geographic distributions of the North American species of Trichinella (T. nativa and its variant T6, T. murrelli, and T. spiralis) are poorly characterized. These species are potentially zoonotic, and biogeographical information is critical to monitoring their status and any distribution changes due to climatic and man-made environmental impacts. Therefore, it is important to more precisely identify their current geographical ranges. New programs using climate, land cover and elevation have been developed in conservation biology for modeling animal species distributions. The maximum entropy model (Maxent) is particularly useful because of its ability to predict distribution ranges with varying levels of probability using limited location records. The Maxent model was used to generate predicted ranges for the North American Trichinella using location records for confirmed species collected over 55 years throughout North America. The resulting prediction models were shown to be robust, and the species maps created are presented.
