EEB 2100 UConn Final Exam
1.Overexplotation: overharvesting natural resources faster than their
replacement
is a main cause of biodiversity loss
2.Overexploitation-Cod Fishing: Atlantic Cod fishery is depleted by
1920's tech- nological advances such as diesel engines that allow for
larger boats
3.Georges Bank: Inundated, highly productive island where the Gulf
Stream caus- es upwellings of nutrients as they are removed from the
bottom of water bodies
Largest source of fish for Europe, and then the America's from 1500-
1900's
4.Fish landings(Ships) in tons: Increase during times of more effort to

,get fish;the great acceleration.
Ultimately crashes in 1992 because Atlantic Cod population becomes so
depleted.
Cod population has never rebounded, this is due to either changes in
ecology(food web) or evolution
5.Fishing down the food web: Fishing for large, apex predators first (e.g
Tuna). Then fishing smaller and smaller as the apex predators get
over fished
6.Overhunting: megafaunal extinctions(Bison): Large scale extinctions of
large mammal species
Population reduced from 50 million to 500 due to ecological trap that
makes them easy to kill with guns
Now subject to genetic bottleneck because so low populations have
reduced genetic variation and adaptability

,7.Overhunting: Government Sponsorship: Bounties placed on gray
wolfs in North America as late as 1965, $20-50 per wolf
Last wolf of Connecticut killed in Pomfret
8.Tragedy of the Commons: Hardin's Tragedy of the Commons- When
consumers maximize their gain on shared resources they destroy those
resources
Self interested customers deplete a shared resource
9.Tragedy of the Commons: Origin: Towns have common greens which
were originally a place townspeople could keep their cattle
Each townsperson then adds more cattle until the green is overgrazed

, Each consumer acts rationally in their own self interest but irrationally
for global interests
10.Maximum Sustainable Yield: Harvesting only up to the rate of
replacement.
11.Limited Entry(fishing): Only a set number of commercial fishing
permits are provided at a time to maintain populations
12.Sustainable Harvesting: Maine lobster: Sustainable practices used for
over 100 years.
Limited entry utilized
Trap limit-800 traps per person
Slot limit- let the largest and smallest lobsters go
13.Consumer knowledge: *Potential exam bonus question*: In New
England you should avoid Cod and Bluefin Tuna because they are
endangered species
