Felidae the Felidae, grouped according to the traditional phenotypical classification with the corresponding genotypical lineages indicated. It includes all of the currently living cat species. There is considerable variation in the taxonomy used for the wildcat. It used to be regarded as "Felis silvestris" with distinct subspecies "F. s. silvestris", "F. s. lybica" and "F. s. ornata" in Europe, Africa and Asia respectively. Since 2017, the IUCN Cat Specialist Group recognises "silvestris" and "lybica" as distinct species. The phylogenetic relationships of extant felids are shown in the following cladogram, based on the molecular phylogenetic analysis of Johnson et al. (2006). The
Felidae Conservation Fund Yellowstone ecosystem by examining predation, behavior associated with human development, and interactions with wolves, grizzly bears and black bears. The project is operated by Craighead Beringia South with support from Felidae. The Southern California Puma Project examines the progress and implications of habitat fragmentation as puma populations in Southern California become more isolated. Felidae is collaborating with UC Davis Wildlife Health Center on this study, which has radio-collared more than 50 pumas over 7 years. The Asiatic Cheetah Project in Iran is the first detailed ecological study of the critically endangered Asiatic cheetah. Researchers in Northern Iran work to gain
