1. No QOD we have much to do. Get out your homework and be ready to move on

2. Competition Use or defense of a LIMITING RESOURCE
Not the necessarily direct
Ex) if one rabbit simply eats a patch of a limited food plant before another rabbit does, then they are competing with one another even if they never directly interact
Ex) if one rabbit physically denies another rabbit access to food this is also competition

3. Competition
Competition is only one of many interacting biotic and abiotic factors
Has the potential to alter populations, communities, and the evolution of interacting species

4. Limiting Resource
A resource whose availability influences survival and reproduction
This is all of the things we’ve already talked about: food, land, water, shelter, etc.
It could also be another organism to mate with

5. Interspecific Competition
A form of competition in which individuals of DIFFERENT species compete for the same resource in an ecosystem (ex. Food or living space)
Ex) If a tree species in a dense forest grows taller than the surrounding tree species, it is able to absorb more sunlight. Since shorter tree species are shaded, they get less sunlight needed to live.
Ex) Leopards and lions both feed on the same prey, so they can be negatively impacted by the presence of one another since they will have less food.

6. Intraspecific Competition
Members of the SAME species compete for limited resources
Ex) Two males fighting each other over a female
Ex) Wolf packs fighting for food or territory

7. Limiting Factors
Anything that can limit the growth of an organism or population
Can be biotic or abiotic
Limiting resources are ONE example

8. Density-dependent factors
Anything that can alter or reduce a population based on HOW BIG the population is
Usually biotic
Not as much of an issue in small dispersed populations
Denser a population the greater its mortality rate
Ex) predation, competition, disease

9. Density Independent Factors
Factors that do not become a greater or lesser problem when population size changes
Usually abiotic
Ex) Weather, natural disasters, and pollution.
Ex) An individual deer may be killed in a forest fire regardless of how many deer happen to be in that area. Its chances of survival are the same whether the population density is high or low

10. Management Plan Key elements of the plan include: Recovery goals
Livestock protection
Wildlife protection
Must use the following terms: Carryingcapacity, Interspecific/ intraspecific competition, Density dependent/independent factors (related to population growth) Keystone species
