Presentation transcript:

Carrying Capacity: Sustainable population size in an environment

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

Resources & Conditions Present: Sunlight Rainfall/Moisture Climate Soil type Space Landscape/Terrain Food sources Predator levels

Carrying Capacity is not constant: Changing conditions (resource availability) and/or Changing resource use by species

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

Carrying Capacity for a Species:

Overshoot: More individuals of a species living in an area than can be supported over a long time.

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
