Urodelans of VT Flashcards
What is the scientific name of the Eastern Newt
Notopthalmus viridescens
What is the family of the Eastern Newt?
Salamandridae
What is Salamandridae considered?
the “true” salamanders
What is the life history of the Eastern Newt?
- Red efts (the juvenile phase) live exclusively on land for years
- Adults change color and morphology, returning to water to breed
- Lay their eggs individually on underwater vegetation
- Nuptial pads help ID males
- Aquatic or terrestrial brumation
What is the habitat of the Eastern Newt?
- Summers and winters in hardwood forests near permanent water
- Breeds in beaver ponds, ponds, lakes, marshes, etc.
- Common through most of VT except in the conifer-dominated NE Kingdom.
Where are Eastern Newts found?
almost whole map is covered except the top middle and right hand is a little missing
What is the conservation status of the Eastern Newt?
-S5 (common)
- Highly susceptible to Bsal (new pathogen not thought to be in US yet)
What are the field ID marks for the Eastern Newt?
The Eastern Newt as a terrestrial juvenile is reddish-orange with slightly bumpy skin.
As an aquatic adult, the Eastern Newt turns olive green and their bellies reveal scattered black spots on a bright yellow background. They reach 5 inches in length.
Juveniles and adults both have a dark horizontal line going through their eyes and rows of red spots outlined in black along their backs.
What is the family of the mole salamanders?
Ambystomatidae
What are the three mole salamanders of Vermont?
+Jefferson salamander
+Blue-spotted salamander
+Spotted salamander
What is the scientific name of the Jefferson Salamander?
Ambystoma jeffersonianum
What is the family of the Jefferson Salamander?
Ambystomatidae
What is the life history of the Jefferson Salamander?
- Spends most of their life underground (like a mole)
- Overwinters underground- Lays loose masses of 10-40 eggs
- Larvae metamorphose in 2-4 months
- Hybridized with blue-spotted (“The Jeff Complex”)
What is the habitat of the Jefferson Salamander?
- Summer and overwinter in upland forests
- Breeds in vernal pools and other semi-permanent wetlands
- Found in low, hilly areas in soils of high buffering capacity (sensitive to acidity in breeding pools).
Where are the Jefferson Salamander found?
In the lowlands around the mountain range except the North
What is the conservation status of the Jefferson Salamander?
-S2 (rare); please report all sightings
- Acid rain
What are the field ID marks of the Jefferson Salamander?
They grow to 7 inches long. This species has a solid gray-brown body with tiny white flecks on the belly and lower sides. It is a chunky salamander with strong legs, a wide head, and a laterally-compressed tail (like a fish). The head and snout are wider and longer in this species than in Blue-spotted Salamanders but not as wide as the head of the Spotted Salamanders. They usually lay their eggs in sausage-shaped gelatinous masses of 10-30 eggs. Unlike Spotted Salamander egg-masses, Jefferson Salamander masses tend to not hold their shape when out of the water.
What is the scientific name of the Blue-spotted Salamander?
Ambystoma laterale
What is the family of the blue-spotted Salamander?
Ambystomatidae
What is the life history of the blue-spotted salamander?
- Spends most of their life underground (like a mole)
- Overwinters underground
- Lays single gelatinous eggs (but hybrids with Jefferson salamanders lay egg masses of ~10 eggs)
- Larvae metamorphose in 2-4 months
- “Jeff Complex”
What is the habitat of the blue-spotted Salamander?
- Lower elevation vernal pools, flood plains, semi-permanent pools, marshes, and swamps.
- Populations scattered
Where are blue-spotted Salamanders found?
Lower elevation and mostly around Lake Champlain, but only on the left side of the mountain range. Largely a Champlain lowlands species.
The Jefferson Salamander is found on the left and right of the mountain range
What is the conservation status of the blue-spotted salamander?
- S3 (uncommon); please report all sightings
What are the field ID marks of the Blue-spotted Salamander?
The Blue-spotted Salamander is the smallest of Vermont’s three mole salamanders. Mole salamanders spend most of their lives underground (like moles) except when migrating to and from breeding wetlands, pools, and ponds. They all have sturdy bodies and strong legs. They grow to 5 inches long and are black with small light blue spots on their backs and sides.
