First photographic evidence of an insular dwarf fox (Urocyon sp.) on the island of Cozumel, Mexico
Carnivores confined to islands often undergo rapid evolutionary divergence, resulting in dwarfism. However, many of these insular species remain poorly understood. Island carnivores are among the most...
