- Many eyes hypothesis
- Frugivorous primate colonies
- Optimum Hunting Size
- The grates differences in sex spatial ability is seen in?
- a individuals in large groups spend less time watching for predators and more time doing other activities such as eating.
- b Among frugivorous primates, the amount of time spent foraging per day increases as a function of group size and potentially sets an
upper limit of group size.
- c polygynous or promiscuous
mating systems, and especially those with scramble competition
- d Optimum group size in lions varies depending on the prey they take - 2 lions in the case of eating Thomson's gazelle.
- e includes trips outside the
home range, usually in search of mating opportunities or suitable
habitat. This type of movement includes natal dispersal.
5 Multiple choice questions
- In many species of mammals, members of one sex disperse
while the other sex are philopatric (breeding near the place they were born). Among mammals it is usually the male that disperses.
- with conspecifics for food, shelter, or mates. Most mammals are polygynous and males may be forced to disperse as they compete for access to females
- Many marine mammal
strandings have been associated with changes in the earth's
magnetic field possibly due to solar flares or areas of magnetic
- Most bats hibernate.
Some bat species do migrate - most often to and from caves used
as hibernation sites. Some little brown bats migrated over 200 km
from hibernation caves in Vermont to summering sites in
- Many species who live in large
groups have the challenge of
identifying their young when
returning from a foraging trip.
5 True/False questions
Station Keeping → Used to be defined by round trip but now one-way travel also counts
Tradition → a behavior passed from one generation to the next
through the process of learning.
Nature vs. Nurture study participants → After this series of experiments it was concluded that:
1. The choice of grassland by grassland deer mice is predetermined genetically.
2. Early grassland experience can reinforce this innate preference
but is not a prerequisite.
3. Early experience in either forest or grassland did not reverse the
4. Twenty generations of lab rearing resulted in a reduction of
hereditary control over habitat choice.
5. Lab raised stock retained the capacity to "imprint" on early
grassland experience but not forest. .
He concluded that learned responses were primary basis of
restriction and that genetics was secondary.
Allee Effect → Behavior that is potentially costly to the individual but beneficial to others
Piloting → a process by which most species return to a home range, nest
site or den
