Synaptomys australis, the Florida bog lemming, is an extinct species of bog lemming that occurred in Florida during the Late Pleistocene. Taxonomy
The southern bog lemming (Synaptomys cooperi) is a small North American lemming. Its range overlaps with the other species in genus Synaptomys , the northern bog lemming , in southeastern Canada , but extends farther south.
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 ...
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: "†".
† – A species that is globally extinct * – A species that is known to have been introduced by humans and was never present by natural immigration. Some animals have gone extinct several times and then recolonized. The date given is of the most recent extinction. Species that have been introduced or reintroduced by humans are noted.
This page features lists of species and organisms that have become extinct. The reasons for extinction range from natural occurrences, such as shifts in the Earth's ecosystem or natural disasters, to human influences on nature by the overuse of natural resources, hunting and destruction of natural habitats.
