map - Historic and current distribution of the tiger-cat species complex: savanna tiger-cat (Leopardus tigrinus), Atlantic Forest tiger-cat (Leopardus guttulus), and the new species, the clouded tiger-cat (Leopardus pardinoides).

graphic - charts - whisker plots - Multidimensional niche parameters showing the variables with higher impact that shape the hyperdimensional niche of the tiger-cats.

maps - Current and historic range of the clouded tiger-cat (Leopardus pardionides) in Central America (a), the northern Andes (b), and the southern Andes (c).
