General Predictions of Optimal Foraging:
Optimal foraging theory is a model that _____
A) predicts how an animal behaves when searching for mates.
B) predicts the best strategy that an animal can use when foraging.
C) predicts how animals minimize their fitness while they forage.
D) disregards environmental constraints.
You observe the reproduction rates of capybaras over the course of one breeding season in the same population. Which individual is the most "fit":
A) Individual 1: 10 offspring, 5 survive to adulthood
B) Individual 2: 30 offspring, 4 survive to adulthood
C) Individual 3: 7 offspring, 6 survive to adulthood
Which of the following is NOT a condition for selection on tameness in silver foxes?
A) Tameness is related to coat color
B) Tameness is related to reproduction
C) Tameness is heritable (at least in part)
D) There is variation in tameness within the fox
Which of the following is NOT a prediction or assumption of the simple optimal foraging theory model
A) Whether or not a less profitable food item will be chosen depends on its abundance.
B) Whether or not a less profitable food item will be chosen depends on the abundance of more profitable food items.
C) The encounter rate for each food type depends on its relative abundance in the environment.
D) When overall food abundance increases, optimal foragers will become more selective.
Which of the following statements about the optimality modeling framework is TRUE?
A) It is does not incorporate evolutionary constraints
B) Fitness is the common currency
C) It can be used to explain previous observations, but not to make predictions
D) Models built under the optimality framework incorporate all possible biological details
