Q

Special Concern

A 
species that may become a threatened or an endangered species because of a combination of biological characteristics and identified threats 
ex) Eastern Wold 
Black-tailed prairie-dog 
Harlequin Duck 
(due to oil/gas and climate change)

Q

Areas with high population density

and agriculture

A

-have high number of species at risk
due to habitat loss, wetlands loss, human use
human impact= major factor

Q

Turtles of Point Peele Island

A 
Map Turtle= special concern 
Wood turtle= endangered 
Spiny soft-shelled turtle=threatened 
Midland Painted Turtle=not at risk 
Stinkpot turtle= threatened 
Blandings Turtle= threatened 
Common Snapping turtle= special concern 
Spotted turtle= endangered 
why? poaching, pollution, habitat loss, Carolinian ecosystem is endangered

Q

How turtles die

A

Roads=direct mortality, hit by car
Predators and roads- racoons=generalist species
Contaminants- DDT poisoned turtles and changes strength of egg shells

Q

Causes

A

habitat loss- deforestation
over-harvest- shooting, people eating too much
exotics
pollution

17
Q

Extinction-Prone Species

A

specialized needs (feeding, breeding, nesting)

  • fixed migrations (caribou in North disrupted by Alaskan Pipeline)
  • limited distribution- exotic species can kill them all off due to small niche
  • economically valuable- black bear organs being poached and sold on the black market
  • low reproduction rate- bowhead whale does not reproduce until 15
  • incompatible with people
  • oil and gas development
  • cost/benefit analysis of each species
  • co-dependance (muscle and trout)
18
Q

Threats?

A
  1. Habitat Loss
  2. Non-natives
  3. Over-exploitation
  4. Pollution
  5. Pest control
  6. Collecting
  7. Climate Change
    * think of solution for each threat
19
Q

Solutions?

A
  • re-create habitat
  • antibiotics in feed pile
  • control non-native species
  • clean up pollution
  • create protected area
  • cut off illegal trade
  • education
20
Q

Other calls to action

A
  • INternational conventions and agencies
  • research and monitoring
  • habitat protection
  • captive breeding
  • legal actions
21
Q

CITES

A

convention on the international trade in Endangered Species

22
Q

In Situ Conservation

A

conservation of ecosystems and maintenance and recovery of populations in their natural environments

  • protect species in natural environment
    ex) whooping crane
23
Q

Ex situ conservation

A

conservation of a species or genetic materials in an artificial environment, away from its natural habitat
ex) zoo- take animals out of natural habitat

24
Q

In 2003

A

high number of special concern and endangered species

lower extinct and extirpated
