Synaptomys australis, the Florida bog lemming, is an extinct species of bog lemming that occurred in Florida during the Late Pleistocene. Taxonomy
Very little information is available about this species' life as they are hard to find and study. [3] The northern bog lemming is a small, reddish-brown rodent with a short tail, and distinct markings on their upper teeth. These markings, along with having four pairs of teats, distinguishes this species from the southern bog lemming. [4]
Southern bog lemmings are found in eastern North America, from southern Quebec and Manitoba in Canada to western Minnesota, to northwestern Georgia, to southwest Kansas, and east to the Atlantic Coast of the United States. This species is more common in deciduous and mixed coniferous–deciduous forests.
The Canadian lemming was formerly thought to be a subspecies of the Siberian brown lemming (Lemmus sibiricus), but those were split into two distinct species. They were still considered the same species as the Beringian lemming ( Lemmus nigripes ); the combined species was named the North American brown lemming with the scientific name L ...
Approximately 0.068% of all evaluated plant species are listed as extinct in the wild. The IUCN also lists one plant subspecies as extinct in the wild. This is a complete list of extinct in the wild plant species and subspecies as evaluated by the IUCN. All are vascular plants (tracheophytes).
Range maps are provided wherever possible; if a range map is not available, a description of the canid's range is provided. Ranges are based on the IUCN Red List for that species, unless otherwise noted. All extinct species (or subspecies) listed alongside extant species went extinct after 1500 CE, and are indicated by a dagger symbol: "†".
