- Cooperative Rearing of Young in Carnivores (Meerkat)
- Ungulate Migration
- Degrees of cooperation
- Big Horn Sheep reason for grouping
- a Many species of seals and sea lions migrate thousands of kilometers each year from island breeding and molting sites to feeding areas.
- b Large ungulates migrate impressive distances as well.
Barren ground caribou herds move migrate 1000+ km between
wintering and summering grounds.
- c In mongooses and meerkats, subordinate females help rear the young of the dominant females.
- d The degree of cooperation
ranges from none to complex coalitions and alliances. In some species, kinship is important but in others coalitions among nonrelatives are also common, as in hamadryas baboons and chimpanzees.
- e 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

5 True/False questions
Benefits of Mammals Living In a group → Benefits from Physical factors Protection against Predators Finding and Obtaining food
Reason for dispersal (reduce Competition) → 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.
Male Dispersal → 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
Lion Dispersal Pattern → 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
Allee Effect → Minimum pack size is 5,
more than that and some can stay
back. This minimum group size is
