1 Carrying Capacity: Sustainable population size in an environment http://www.sustainabilitylabs.org/files/images/Sust.%20Diagram%202.preview.jpg

2 Carrying Capacity: Maximum population of a given species that can survive indefinitely in a given environment Depends on: Conditions & resources available in habitat Resource consumption by species

4 Carrying Capacity is not constant: http://www.activistangler.com/storage/drought.jpg?__SQUARESPACE_CACHEVERSION=1362064244633http://labsaints.com/wp-content/uploads/water-pollution.jpg Changing conditions (resource availability) and/or Changing resource use by species

5 Limiting Factors: Anything that can change a species’ population Natural & Human influence Disease Parasites Accidents Fire Floods Storms Starvation Hunting Predation Habitat Loss Drought Pollution Shade

6 Carrying Capacity for a Species: http://culturingscience.files.wordpress.com/2010/10/carrying-capacity.jpg

7 Overshoot: More individuals of a species living in an area than can be supported over a long time. http://www.paulchefurka.ca/Overshoot_2.jpg

8 Carrying Capacity Overview: Defined as a sustainable population level for a species within an environment Influenced by abiotic (non-living) and biotic (living) factors Connecting resource use & availability with population http://nssdc.gsfc.nasa.gov/image/planetary/earth/apollo17_earth.jpg
