- Testosterone in Belding's Ground Squirrels
- How much time do offspring spend with their parents?
- What drives Catecean migration?
- Northern Elephant Seal Inbreeding
- In order for homing to occur an animal must have
- a At the turn of the last century it was estimated that there were only
between 20 and 50 northern elephant seals remaining. Now there are about 160,000 and growing at 6% per year. This suggests a severe genetic bottleneck and a minimal amount of genetic diversity.
- b - a sense of direction (some form of compass)
- a sense of location (understand where it is starting from)
- c Food supply does not drive this migration, but it is suggested that it
is to minimize heat loss in the newborns
- d dispersal appears to be the prenatal
effects of testosterone on the male embryo during development
and the attainment of critical body mass after birth.
- e Large brained and highly social
species of primates and dolphins spend as much as 25% of their
lives being dependent on parents and other relatives
5 Multiple Choice Questions
- African wild dogs are cooperative
breeders living in packs of up to
20. Some will stay back and
protect the pups while the rest
- matings between members of different populations within
a species leads less-fit offspring. . Members of a population may possess adaptations to local
conditions that are potentially lost through outbreeding.
Two areas may differ in temperature, humidity, or types of food
and if each population is genetically adapted to these conditions
they would be better off mating with individuals with those same
- requires a mental map of
the terrain but does not require a compass. In principal it could be
used for longer trips
- In prairie dog colonies the amount of agonistic behavior per individual increases as a function of group size
- males leave (usually
before 4 years old), to become nomads or form coalitions that take
over new prides. Competition with other males is important as
most departures occur when a new coalition takes over. Some
males do leave voluntarily.
5 True/False Questions
Coalition Control → Most mammalian movements occur in a relatively small area
such as when an individual acquires resources within its home
Many eyes hypothesis → individuals in large groups spend less time watching for predators and more time doing other activities such as eating.
Factors Affecting Spatial Ability → Mammals are assumed to have a cognitive map, sex differences in spatial ability
Organisms that have reached the level of Eusociality → the naked mole rat
Assembling Members for Location of Mates → males of several species defend small territories and display to attract females for copulation. Examples include hammer-headed bats, topi, and fallow deer.
