Lecture 6: Behavioural Ecology Flashcards
1
Q
Proximate Causes
A
- immediate
- how the behaviour occurs
2
Q
Ultimate Causes
A
- the evolutionary and historical reasons why the behaviour occurs
Ex. puppy dog eyes why does the behaviour occur and its evolutionary history
3
Q
Optimal Foraging Theory
A
- Animals will maximize the amount of energy gained per unit of feeding time (profitability), and minimize the risks involved
- This does not apply well to animals that eat mobile prey
- Animals might not conform to models as evolution is not perfect
- The assumption that energy is in short supply and that this dictates foraging behaviour may not always hold
4
Q
Total Energy Obtained
A
- will increase and eventually level off
- Worms closer will be more profitable than worms further away
5
Q
Cumulative energy Investment
A
- Spent some energy before even starting foraging effort
6
Q
Net energy gained
A
- Relationship b/w total obtained, and cumulative energy invested
7
Q
Monogamy
A
Male mates with one female, both involved in parental care
8
Q
Polygyny
A
Male mates with multiple females, female provides most or all of parental care
9
Q
Polyandry
A
One female mates with multiple males, male provides most or all of parental care
10
Q
Promiscuity
A
both males and females mate with multiple partners
