Lecture 5 The Big Picture Pt 2

Question 1

What are the main reasons for endangered species?

Answer 1

• Habitat loss
	• Overexploitation
	• Pollution
	• Disease
Invasive Species

Question 2

Why might only in-situ conservation not work?

Answer 2

• Destruction of habitats and fragmentation
• Pest species distribution
• Hunting
• Secondary effects: pollution, global warming, super-nitrification
• Conservation of habitats is resource expensive but conservation as a cause is poor.
• War
• Legal Entities can be changed (national parks revoked)
• Size may be too small for a viable population
All animals requirements may not be within the conserved areas. (outside areas also affect inside areas)

Question 3

What can the captive wild animal industry add to conservation efforts?

Answer 3

• Ex-situ captive breeding!!
  
  • Up close education of human audience
  • Controlled research
  • Governmental influence (because industry size)
  • Extra revenue and logistical resource (zoo money handed to various in-situ projects, education and aid for outside programs)
  • An ark for species that are or might go extinct in the wild
  • Expertise created for captive breeding, animal husbandry, and population management. (the experts tend to be here)

Question 4

What must captive breeding (ex-situ) be partnered with?

Answer 4

• In-situ conservation (integrated conservation)

Question 5

Is captive breeding viable? (concerns people have)

Answer 5

• Too few species can be saved
  
  • Survival in the wild
  • Lack of knowledge on species
  • Species concepts vs nature
  • Ideal individual issues
  • Inbreeding and genetic variation issues (small pops)
  • Coordination issues across captive establishments
