BIOL 3130 Lecture 1: Introduction to Conservation Biology

Expanding human demands
Every natural ecosystem has been changed
Extinctions, altered functioning of ecosystems, reduced availability of
resources, soil erosion
Why conservation biology?
Humans 'may' have been responsible for mega-fauna extinctions in the
Americas shortly after human colonization from Asia ~11,000 years
ago
Aristotle (382-334 BC) commented on the widespread destruction of
forests in the Baltic region
Barren landscapes of Turkey, Syria, Iraq and Iran are unnatural
deserts that resulted from mass exploitation of fragile woodlands
Deforestation of Europe by the early 18th Century, forest areas
maintained as private game management and royal preserves
In Great Britain, many forests were gone by 12th century
Southeastern Ontario was largely deforested between 1800-1900
(trend has been reversing since WWII)
Historical Context
A gradual landscape change results in profound transformations.
Half of Hawaii's native birds went extinct soon after Polynesians
arrived
Half of the remaining species of birds went extinct after Captain
James Cook arrived
We consume a large fraction of the planets resources
35% of NPP from oceanic shelves
Consume 60% of freshwater runoff
We now consume 20-40% of the planet's annual net primary
productivity (energy from the sun converted to plant biomass)
Northern part of the world is 10% the population but 50% oil
consumption
Consumption is highly unequal
Present Day:
Agriculture
Urbanity, suburban sprawl, roads
Pollution
83% of the Earth's land surface shows evidence of our impacts
Fertile grasslands = 98% transformed
Ecological Footprint
Economy vs. natural resource industries
Human Challenges: inertia and fear
Response by the scientific community to the environmental crisis:
pollution, loss of biodiversity, loss of ecosystem services
Latest phase of long-standing interest in preserving our natural
resources
Conservation Biology: the scientific study of the nature and status of
Earth's biological diversity with the aim of protecting species, habitats
and ecosystems from excessive extinction rates that are linked to the
modern human enterprise
Endangered species management
Reserve design
Ecological economics
Restoration ecology
Ecosystem conservation
Environmental ethics
Environmental law
Environmental business
Conservation journalism
Conservation marketing
Eco-arts
Multidisciplinary: overlaps with Natural and Social Sciences
Crisis Management: unites theoretical perspectives with the need for
rapid responses to environmental change
Our concerns surpass our solutions
Inexact: when in doubt, use precaution
Varying definitions of wilderness
Value-laden: charismatic mega fauna
Conservation Biology
Early settlers had no interest in conservation
Driven by fear, religion, and desperation
Coincided with the destruction of Native Americans and their
cultures

Few dissenting voices:
Proximity leads to disdain1.
As cities grew, so did the interest in the wilderness
Reaction against the 'de-humanizing' effects of the industrial
revolution and urban living

Document Summary

Extinctions, altered functioning of ecosystems, reduced availability of resources, soil erosion. Humans "may" have been responsible for mega-fauna extinctions in the. Americas shortly after human colonization from asia ~11,000 years ago. Aristotle (382-334 bc) commented on the widespread destruction of forests in the baltic region. Barren landscapes of turkey, syria, iraq and iran are unnatural deserts that resulted from mass exploitation of fragile woodlands. Deforestation of europe by the early 18th century, forest areas maintained as private game management and royal preserves. In great britain, many forests were gone by 12th century. Southeastern ontario was largely deforested between 1800-1900 (trend has been reversing since wwii) A gradual landscape change results in profound transformations. Half of hawaii"s native birds went extinct soon after polynesians arrived. Half of the remaining species of birds went extinct after captain. We consume a large fraction of the planets resources.
