Biodiversity

Front 1

State the 3 types of biodiversity

Back 1

Habitat

Genetic

Species (eveness and richness)

Front 2

What is habitat diversity?

Back 2

The amount of habitats in an area

Front 3

What is genetic diversity?

Back 3

The variation of allels (types of a gene) within a population of species

Front 4

What is species diversity (eveness and richness)?

Back 4

Species Eveness is the abundance of each species.

Species Richness is the number of different species

Front 5

What is systematic sampling?

Back 5

When samples are taken in fixed intervals often across a long line.

Front 6

What is opportunistic sampling?

Back 6

When the samples are chosen by the investigator / sampling whatevers there

Front 7

What is stratified sampling?

Back 7

When a population is divoded into sub-groups/different areas in a habitat are identified and sampled seperately in proportion to their part of the habitat as a whole.

Front 8

Give an advantage and disadvantage of opportunistic sampling

Back 8

It is simple to carry out

Results will be biased

Front 9

What does the "n" stand for in simpsons diversity index

Back 9

The number of organisms in 1 species

Front 10

What does the "N" stand for in simpsons diversity index

Back 10

The total number of organisms

Front 11

How can you tell a habitat has a high biodiversity?

Back 11

It will have a high index of diversity (close to 1)

Front 12

How can you tell a habitat has a low biodiversity?

Back 12

It will have a low idex of diversity (close to 0)

Front 13

Why is it important to have a high genetic diversity within isolated populations?

Back 13

To increase the populations adaptability to changes in the environment e.g. new predator, change in food soure, new desease.

Front 14

Give an example of how zoos manage genetic diversity.

Back 14

By keeping databases with the details of each animal in the breeding program

Front 15

How do humans affect biodiversity?

Back 15

Overpopulation

Urbanisaion

Habitat loss

Pollution

Front 16

How does climate change affect biodiversity?

Back 16

By changing environmental conditions

Front 17

How does monoculture affect biodiversity?

Back 17

Habitat loss

Loss of local plants/animals

Loss of heritage varieties

Front 18

Give ecological reasons for why maintaining biodiversity is important

Back 18

Protecting keystone species and maintaining genetic resources

Front 19

Give an economic reason for maintaining biodiversity

Back 19

Reduces soil depletion caused by continuous monoculture

Front 20

Give an asthetic reason for maintaining biodiversity

Back 20

It protects landscapes

Front 21

What is in-situ conservation?

Back 21

Protecting a species in their natural habitat

Front 22

What is ex-situ conservation?

Back 22

Protecting a species by moving part of a population from a thretened habitat into a new location.

Front 23

Give examples of types of in-situ conservation

Back 23

Establishing protected areas such as wild life reserves and marine conservation zones

Front 24

Give examples of types of ex-situ conservation

Back 24

Breeding organisms in caltivity (i.e. in zoos), and then reintroducing them into the wild and conserving organisms in botanic gardens and seed banks.

Front 25

What is the rio Convention on Biological Dibersity (CBD)?

Back 25

An international agreement that aims to develope international strategies in the conservaion of biodiversity and how to use animal and plant resources in a sustainable way

Front 26

What is the Convention of international Trade of Endangered Species (CITES)?

Back 26

An agreement designed to increase international co-operation in regulating the trade in wild animals and plant specimens

Front 27

What is the countryside stewardship scheme (CSS)?

Back 27

A local agreement to conserve wildlife and biodiversity by promoting specific managing techniques to landowners (i.e. planting hedges)
