Environmental Science
Alison Mummert2012
Northern Flying Squirrel ?
Physical Characteristics
•8 -11 inches•3-5 ounces•Large eyes•Brown fur•White fur on belly
•Flaps btw wrist and ankles.•Long, broad, flat tails.
•Jump/Glide *65 feet *8 mph
•Physical Characteristics/Special Niche
Population density
Pennsylvania 33 Pocono region Warren county and Potter county.
Native to Canada
Biotic Potential•One litter per year.•During the month of May•2-4 offspring K-selective•3 months- first flight test•Sexual maturity at 1 year•Lifespan 3 years• = Low growth rate!
Biome- Mature Conifer ForestTrees Travel Home Protection Food
•Fungi•Nuts •Seeds•Do not hoard food•Do not hibernate
Herbivores
Ecosystem Services?
• Adds biodiversity• Spreading of fungi spores around trees. Aids the trees= take in water, nutrients
= cool streams, fish, purify air
•Keystone species
Endangered Species
1970
Human Impact•Logging of forest•Development
Loss of biome which it depends on.
Trees Travel Home Protection Food
Decline in health of biome.
Loss of Hemlock trees.
-Wooly adelgid
The Northern flying squirrel’s ecosystem service is very
important!
Trees protect the Northern flying squirrel from predators.
Carrying Capacity is very low…without trees!
Food web:Predators:•Owls•Hawks•Foxes•Raccoons•Snakes
Southern flying Squirrel
•Interspecific competition Nest Food.•High Environmental resistance•Carrier of a parasite•Destroying Northern
•Raise Awareness•Protect older forest/invasive species•Hemlock trees (umbrella specie)
Sustainable Solution ?
