Ex-situ and in-situ conservation

Question 1

What is conservation

Answer 1

Maintaining and protecting a living and changing environment

Question 2

what is insitu conservation

Answer 2

process of conserving species in their natural habitat by limiting the impact of human development and maintaing the habitats natural features

Question 3

What are the 2 forms conservation takes place

Answer 3

Legilsation 
Wildlife reserves (including marine conservation zones)

Question 4

Laws can be passed to try to stop the :

Answer 4

1) Stop hurting of animals
2) Stop clearing natural habitats for things like agriculture
3) Stop the illegal trade of endangered species

Question 5

What are examples of insitu conservation:

Answer 5

protected habitats i.e national parks

Question 6

What are examples of ex-situ conservation

Answer 6

Zoos and seed banks

Question 7

What are the conflicts with humans for insitu conservation

Answer 7

The need for indigenous people may conflict with the conservation efforts (food, econmic devleoplment )

Protected animals (increasing population sizes) may start to impact on neaby farmland

Question 8

What are the advantages of in situ conservation

Answer 8

Protects more than one species

More likely to survive in the wild (little human contact)

Can protect the whole population

Question 9

What are the disadvantges of in situ conservation

Answer 9

Hard to enforce bans on hunters/ pachers

No protection from climate change

Question 10

What are the disadvantage of ex- situ conservation

Answer 10

Can be expensive to set uop

Can only care for small numbers

less successful at reintroduction

Breeding can be less successful in captivity

Question 11

What are the advantges of ex situ conservation

Answer 11

Requires little space and eliminates predators and poaches

Question 12

What are the problems with captive breeding and reintroduction 1/3

Answer 12

not enough space or sufficient resources in zoos and parks for all the endangered species

animals that have been bred in captivity may have great problems in adjusting ti unsupported life in the wild

Question 13

What is the role of seed banks

Answer 13

place where seeds are stored to preserve genetic diversity for the future.

Question 14

What is it better to store seeds than adult plants

Answer 14

seeds are produced in excess

Take up little space and can store a large number

Cheaper to transport

Great genetic diversity

Question 15

What role do national parks play in conservation

Answer 15

protect and conserve native speices

Question 16

examples of national parks

Answer 16

Serengeti national park (Tazania)

Everglades (USA)

Question 17

What is ex-situ conservation

Answer 17

conservation living organisms outside their natural habitat

Question 18

How do Zoos help?

Answer 18

They have captive breeding programmes

Zoos also help to conserve gene pools

once event is over the species can be reintroduced into suitable habitats

Question 19

Why do seed collections contain samples from a range of populations and areas?

Answer 19

To maximise gentic diversity

Question 20

What are the reasons for keeping zoos

Answer 20

Education about about endarged species
Save endarged species
Protect from poachers
breeding programmes

Question 21

Reasons agasint zoos

Answer 21

Certain species favoured
captive breeding programs may not successfully release animals back into the wild
 animals suffer stress, boredom, confinement, change behaviour / habitat differs

Question 22

how do seed banks select seeds for storage?

Answer 22

from different plants to provide genetic diversity

it also x rayed to check for viable embryos

Question 23

What conditions do seeds need to be kept in?

Answer 23

Dry and cold
To prevent enzyme activity
To prevent germination of seeds

Question 24

How does captive breeding ensure getnic diviersty

Answer 24

It will increase population
Stud book kept of breeding programmes
Zoos select breding partners
Inter zoo exchange for breeding to prevent inbreeding

Question 25

Problems with captive breeding

Answer 25

small population
Small gene population\
Low gentic diversity
inbreeding

Question 26

Why might a zoo create a captive breeding breeding

Answer 26

Population of organism falling
Breeding programme will increase numbers
Enable reintroduction

Question 27

Why is reservation better than the CB

Answer 27

Less discromfort for animals
More likley to breed in a natural environment
Natural interspecifc relationships to exist
No problems when reintroduced back into the wild
