Interaction Conservation

Interaction Conservation

• Thompson, J. N. 1996. Evolutionary ecology and the conservation of biodiversity. TREE 11:300-303.

• Both ecological and evolutionary consequences

• Geographic-mosaic theory of evolution / coevolution

Geographic Mosaic Theory

• Species are groups of genetically differentiated populations

• Outcomes of interactions vary among communities

• Interacting species differ in their geographic ranges

Should we focus conservation efforts on:

A. Wilderness areas: Pristine areas far from human contact

B. Wildlife areas bordering “high density” human populations

Biodiversity and Human Conflict

• 4 spp. of birds found on islands of Western Pacific delisted or upgraded (listed on the basis of surveys immediately following WWII)

• The civil war in the Democratic Republic of Congo has devastated wildlife – Garamba Park: ~ 4,000 / 12,000 elephants killed between 1995 and 1999.
