Identification
The Central Newt is a subspecies of the Eastern Newt, and is closely related
to the Red-spotted Newt. Compared to the Red-spotted Newt, the Central Newt
is smaller, thinner, and usually lacks red spots. When spots are present they
are generally small and partially outlined in black. The coloration of the dorsal
surface is quite variable and may range from olive-green to yellowish or olive-brown.
Geographic location will aide in the identification of this species.
Distribution and Status
The Central Newt ranges from Lake Superior through east Texas and east to South
Carolina. In much of Michigan and through the Deep South, this species intergrades
with the Red-spotted Newt. The Central Newt is found in all Midwest states except
Ohio. The species is listed as State Threatened in Iowa.
Ecology
A resident of low, marshy land, swamplands, woodland ponds and ditches, as well
as river bottoms, the Central Newt has a complicated life cycle. Most commonly,
they cycle from the egg, to aquatic larva, to terrestrial eft, and then to an
aquatic adult. Adults can also be either gilled (aquatic) or terrestrial (they
have lungs). Efts are commonly found in leaf litter, while aquatic adults can
be found hiding amongst aquatic vegetation. Aquatic adults are less common in
populations of this species compared to the Red-spotted Newt.
Threats and Management Issues
Because of their ability to thrive in weedy farm lands, Central Newt populations
have remained relatively secure. Interestingly, populations have increased in
areas where beavers have been reintroduced.
