Conservation in a changing world
What is conservation biology?
Why consider climate change for conservation planning?
Why is connectivity important?
Conservation Biology
Application of science to conservation problems, addressing the biology of species,
communities, and ecosystems that are perturbed, either directly or indirectly, by human
activities or other agents.
Its goal is to provide principles and tools for preserving biological diversity.
Conservation Biology
“A conservation biologist may have to make decisions or recommendations about design and
management before he or she is completely comfortable with the theoretical and empirical
bases of the analysis.
Tolerating uncertainty is often necessary.
Why should we care about conserving biodiversity?
Ecosystem Function
Direct Economic Uses
Indirect Economic Uses
Ethical Reasons
Aesthetic Reasons
