Q

Conservation Biology has three goals

A
  1. To document the full range of biological diversity on Earth(search for factual knowledge)
  2. To investigate human impact on species, genetic variation, and ecosystems(search for factual knowledge)
  3. To develop practical approaches to prevent the extinction of species, maintain genetic diversity within species, and protect and restore biological communities and their associated ecosystem functions (normative discipline)

Q

Normative discipline

A

Normative discipline:
It embraces certain values (preserving life) and attempts to apply scientific methods to achieving those values (Lindenmayer and Hunber 2010).

***values and apply scientific method
-ex: medical science
-conservation biologists prevent loss of biodiversity because they believe preserving species and natural communities to be an ultimate good

Q

Conservation biology differs from

A

Conservation biology differs from agriculture, forestry, wildlife management, and fisheries biology in its primary goal:

Long-term preservation of biodiversity with economic factors secondary.

(make no $, we want to preserve life.)
Conservation biology-more general theoretical approach to protecting the entire range of biodiversity

Q

Conservation biology merges

A

It merges applied and theoretical biology and incorporates ideas and expertise from a broad range of fields outside the natural sciences, toward the goal of preserving biodiversity.

Q

Environmentalism
versus
Conservation biology
Are they the same?

A

they are closely associated
environmentalism-widespread movement characterized by political and educational activism with the goal of protecting the natural environment from destruction and pollution.

Conservation biology- is a scientific discipline, based on biological research.

Q

Roots of conservation biology

A

Religious-many see people as spiritually and physically connected to plants and animals. Other religions protect wild areas for their spiritual experience

Cultural-painters Ralph Waldo, David Thoreau, romantic depictions of Hudson River school. (philosophers)

Philosophical-John Muir Aldo Leopold argued for preserving natural landscapes (scientists) Aachen Carson-pesticides

Metaphysical – scientific e.g., Gaia hypothesis-viewed earth as having “super organisms” whose biological, physical and chemical properties interact to regulate characteristics of the atmosphere and climate

Q

INTERNATIONAL SCOPE

A
  • United Kingdom: earlier leaders
    1865 First conservation society

International Earth Summit, Rio de Janeiro,
Brazil, 1992
- Convention of Biological Diversity: CBD
178 countries signed

-early 19th century began to realize and extinction and harm -this formed the British conservation movement in 1865- founding of commons, open spaces and footpaths preservation society in 1868

20th century acts passed to protect life.

CBD-obligates countries to protect their biodiversity but also allows them to obtain a share in the profits of new products developed from that diversity

Q

sea turtles

A

sea turtle pop. shrunk-> Brazilian gov. set out to design conservation program
-lacked basic info
-1980, TAMAR projecto:
-2 year survey
-tagging sea turtles
interviewed villagers
shadow changes temp. collected eggs, observed people college eggs, TAMAR is main source of income for some villagers.

17
Q

ethical principles

A

1.The diversity of species and biological communities should be preserved.
2.The untimely extinction of populations and species should be prevented.
3.Ecological complexity should be maintained.
4.Evolution should continue.
5.Biological diversity has intrinsic value.

-not every conservation biologist accepts every principle and they don’t need to.

18
Q

biophilia

A

genetic predisposition to fell affinity for biodiversity .

19
Q

1.The diversity of species and biological communities should be preserved.

A

-most agree that biodiversity is appreciated
-biophilia
-acknowledge economic value of biodiversity

20
Q

2.The untimely extinction of populations and species should be prevented.

A
  1. ethically neutral event, it happens as a process of evolution however now populations are decreasing and going extinct without new pop. replacing them.
21
Q

3.Ecological complexity should be maintained.

A

we can only have ecological complexity with natural communities. cannot be in man made zoos or botanical gardens

ex: plants have special flowers because they are pollinated by special insects in the wild

22
Q

4.Evolution should continue.

A

evolution leads to new species and biodiversity increases
-avoid humans preventing or limiting evolution
-preserving endangered species is important but since they are cut off from natural environment, we don’t know if they will survive if they are released

23
Q

5.Biological diversity has intrinsic value.

A

species and community have a value of their own besides the values we place on them.
value=their very existence

24
Q

Conservation is is a crisis

A

discipline
-time pressured decisions
-provide advice
-make recommendations
-we have seen small positive changes
