1

What is consecration biology

The applied science of maintaining biological diversity on Earth

2

What are the foundations in conservation biology

In biology and ecology

3

What are the parts of conservation biology

Social environment
Physical environment
Biological and ecological context
Researchers, practitioners and citizens

4

What is conservation biology focused on

Applied practice of natural resource management. Steeped in personal, professional and social ethical questions.

5

What did Aldo Leopold day

Our job is to harmonise the increasing kit of scientific tools and the increasing recklessness in using them with the shrinking biotas to which they are applied. In the nature of things we are mediators and moderators and unless we can help rewrite the objectives of science we are predestined to failure.

6

How is conservation biology an evolving field

Growing focus on neglected fields (social sciences), neglected systems (marine and freshwater), capacity building and international engagement. Increasing policy focus and policy voice

7

What happened in 1978

The first international conference on research in conservation biology, university of California, San Diego in La Jolla

8

What are some good key journals

Conservation letters
Biological conservation
Frontiers in ecology and the environment
Oryx

9

What are the aims of conservation biology

Maintain what we have and increasingly think about ways to restore.
Document full range of biological diversity.
Investigate human impact on species, communities and ecosystems.

10

What do we want to develop practical approaches for

To prevent species extinction.
Maintain diversity.
Maintain ecosystem functions and the interactions among species.
Restore injured biological communities and systems.

11

Why does consecration not equal preservation

Preservation has a historical background linked to the transcendental movement whereas conservation had a very utilitarian conservation ethic.
Now, preservation attempts to maintain remaining areas untouched by humans and conservation is an amendable to resource use in a sustainable way.

12

What kind of approach is preservation and what does it focus on

Hands off approach focusing on the intrinsic values of nature

13

Why is conservation is important

Important to human development which is inevitable and important

14

Why should we conserve

The value of species
Direct economic values
Strategic values

15

What is the value of species

Instrumental/utilitarian/ use values
Ecological values.
Intrinsic (non use) values.
Uniqueness values.

16

What are the direct economic values

Food, medicines, clothing and fuel.
Pollination, pest control.
Recreation - direct consumption use like fishing and hunting or non consumption like photography.

17

What are strategic values

Indicator species and umbrella species and flagship species

18

What are indicator species

They reflect the quality of the environment which lets us evaluate changes and aspects of community composition - it’s instrumental.

19

What are umbrella species

They had demanding habitat requirements and it means that if we protect them it will have a lot of downstream impacts for other species

20

What are flagship species

Popular, charismatic and serve as symbols and rallying points to stimulate conservation awareness and action

21

Example of an important instrumental species

Freshwater invertebrate indicators - BMWP score system measures water pollution at a particular site based on species indicator

22

Example of an umbrella species

Jaguar
Eats 85 species.
Requires large tracts of land.
Requires corridors.
Sympatric with other felids.

23

What does the conservation of jaguars justify

The linking it protected areas

24

What are the cultural values

Scientific and educational.
Spiritual.
Cultural.
Historical.

25

What do Darwin’s finches do

Help us understand evolution

26

What are the ecological values of keystone species

Have impacts on their community or ecosystem that is large and disproportionately large relative to its abundance

27

How are beavers keystone species

They are habitat engineers, dead wood in water provides habitats for other species and flooding regimes they create cause wetlands

28

What are the ecological values of dominant species

They constitute a large proportion of the biomass or an ecosystem. A lot of species so their ecological distribution is disproportionate.

29

What are the ecological values of diversity ecological functions

Play key, large roles in ensuring the function of the overall ecosystem. Dung beetles play critical roles in nutrient cycles

30

Examples of keystone species

Wolves
Bats
Fig trees
Disease causing organisms
