ALEXUS ROBINSON2/7 /14
PERIOD 3 – ENVIRONMENTAL SCIENCEENDANGERED/THREATENED SPECIES
The Bog Turtle
Common NameBog turtle
Latin NameGlyptemys muhlenbergii
Life History• Sexually mature at the
ages of 8-11 (both ages)
• Mate in the spring (after hibernation) (can last 5-20 minutes)
• Females can mate once, twice, or not at all.
• Males try to mate as many times as possible
• Nesting time is between April and July
• Most eggs are laid in June
• Females lay 1-6 eggs
• Many offspring do not survive sexually maturity
• After eggs are laid they go through an incubation period (last 42-80 days)
Life History (Continued)•If laid in colder weather, they incubate through the winter and hatch in the spring
•Babies are about 2.5 cm when hatched in late August/September
•Females are born smaller and grow slower
•In the first 4 years, they double in size (are not fully grown until they are about 5 or 6 years of age)
•Have a maximum lifespan of 50 years (average lifespan is 20-30 years)
Physical CharacteristicsSize: 3-3.5 in
Weight: 3.9 oz
Color: Bright yellow or orange spot on both sides of their head and neck. Dark body color. With orange-red splotches on the inside legs of some turtles. The upper shell is usually black. The lower shell can have cream and black blotches
ReproductionAge: 8-11
Gestation: About 3 months
Litter Size: 1-4 eggs
Food and Water PreferenceFood: Seeds, berries, shoots, invertebrates, insects/insects larvae, crayfish, mollusks, worms, snails, slugs, amphibians, nestling rodents, and nestling birds
Water: Freshwater
Habitat Wetlands, meadows, bogs, and marshes
DistributionTerritory and Range
Ecology and Behavior•Active during the day, sleeps at night
•Wakes up, sunbathes until warm – searches for food
•Stays in dense underbrush, underwater, or buried in mud during winter months
•Stays out of the sun during the hottest hour
•Late September – March/April = hibernation
•Male = territorial
Predators, Parasites, and DiseasePredators: Snapping turtles, snakes, muskrats, striped skunks, foxes, dogs, and raccoons
Parasites: Parasitic flies
Disease: Bacterial infections, and bacterial aggregates
Cause of ListingHabitat loss from the draining and filling of wetlands for farming and development, including housing, roads, and golf courses. Illegal collection of bog turtles for the pet trade
Status (Delaware and Federal)Delaware: Threatened
Federal: Threatened
Conservation Management Needs•Field surveys
•Radio transmitters
•Breeding in captivity
Impacts to Ecosystem if Eliminated Food source for many animals
