Study Notes
Symbiotic Relationships
-
Commensalism is a relationship where one organism benefits and the other is neither harmed nor benefited.
- Birds on giraffes are an example of commensalism because the birds benefit from a perch and the giraffes are not affected.
-
Protocooperation is a relationship where both organisms benefit, but the relationship is not essential for survival.
- Egrets with buffaloes are an example of protocooperation because the egrets benefit from finding food by eating insects disturbed by the buffaloes, and the buffaloes get rid of some annoying insects.
Animal Behaviour
- Ethology is the scientific study of animal behavior.
Competition
-
Apparent competition occurs when two species compete for the same resources, but the competition is indirect.
- Exotic shrubs and trees competing for the same seed predators is an example of apparent competition.
Harmonious Interactions
- Harmonious interactions occur when both participants benefit.
Hamilton's Rule
-
Hamilton's rule states that an individual will help another individual if the benefit to the recipient (rB) is greater than the cost to the individual (C).
- The formula for Hamilton's rule is: rB > C.
- 'r' is the coefficient of relatedness.
- 'B' is the benefit to the recipient.
- 'C' is the cost to the individual.
Amensalism
-
Amensalism is a relationship where one organism is harmed and the other is not affected.
- Trampling of grass due to the movement of animals is an example of amensalism.
Social Behaviour
-
Allogrooming is a social behavior where one animal grooms another.
- Observing a monkey take a tick out of another monkey's head and eat it is an example of allogrooming.
Behavioural Analysis
- Ethogram is an inventory of behaviors exhibited by an animal during a behavior exercise.
