5 Multiple choice questions
- Because of the prevalence of polygyny, and associated tendency for males to disperse as they reach maturity, adult males are generally not related to other adults in the group. Males leave before they reach the age of maturity (sexually) and fathers leave before their daughters reach the age of maturity
- most mammalian social systems are arrange matrilinearlly; mothers and their offspring may stay together and groups are this composed of mothers, daughters, aunts, and nieces
- Mammals are assumed to have a cognitive map, sex differences in spatial ability
- requires a mental map of
the terrain but does not require a compass. In principal it could be
used for longer trips
- Birds but enough has been done on mammals to show that they
use the same mechanisms. Most mammal research has been done on bats and mice.
5 True/False questions
Bats migration and Hibernation → 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
Belding's Ground Squirrels relative → In Belding's ground squirrels,
females are philopatric and
engage in altruistic alarm calling,
whereas males who disperse
away from relatives do not make
alarm calls. This suggests an optimal
inbreeding strategy in which
matings between close relatives
are avoided, but matings with
Belding's ground squirrel
more distant relatives are favored.
Big Horn Sheep reason for grouping → in bighorn sheep the locations of feeding areas and migration routes are remembered by older members of the band and this information is transferred to subsequent generations via tradition
Cooperative Rearing of Young in Carnivores (Lions) → Among carnivores, lionesses
share the nursing of cubs in the pride, and subordinate wolves
regurgitate food for the alpha female and her litter.
Society → A group of individuals of the same species that is organized in a cooperative manner, extending beyond sexual and parental behavior.
