NATURE UNBOUNDLESSON 8 – DIVERSITY & DISTURBANCE OF BIOLOGICAL COMMUNITIES
Conservation
Mr. Dieckhoff
WHAT WILL THE AREA BELOW LOOK LIKE IN 2091?
Peck Ranch Conservation Area 100 Year Study
BIOLOGICAL COMMUNITY
Biological Community – Structure – the living
organism in a biological community
Function – how organisms interact to sustain the community
HOW HEALTHY IS A POPULATION Species Richness –
Relative Abundance –
Is this a healthy forest?
WHICH IS A HEATHIER INSECT COMMUNITY?
BIODIVERSITY
Biodiversity – all the species on the planet (over 10 million)
Components species richness and relative abundance Genetic diversity Different ecosystems that exist within a larger
region
BIODIVERSITY
Affected by:
MISSOURI BIODIVERSITY AREAS
Feature-Species Management –
Community Management –
SPECIES RICHNESS DEPENDS ON WHO LEAVES AND WHO ENTERS
Immigration – entering of new species into community
Extirpation – existing species leaving community
Equilibrium point –
SUCCESSION
Succession – Primary – Secondary –
Disturbances – departure of typical environmental conditions (fire, tornados, ice storms, floods)
Primary successional community – Climax Community –
SUCCESSION
