- Outbreeding Depression
- Scale color denotes
- Organisms that have reached the level of Eusociality
- Does inbreeding hypothesis predict which sex should disperse?
- Factors Affecting Spatial Ability
- a 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
- b how old the seafloor is in millions of years.
- c the naked mole rat
- d Mammals are assumed to have a cognitive map, sex differences in spatial ability
- e No. While the inbreeding hypothesis predicts that one sex should
disperse it does not predict which sex.
5 Multiple choice questions
- Most juvenile pikas stay in their natal patch for life but individuals occasionally disperse both within and between patches of talus Of those that move 100 m or more,
most were females
- Male-male competition, mate acquisition, protection of young cubs, inbreeding avoidance
- If two animals reared from birth under identical environments
differ in habitat preference when adults, the conclusion would be
that the differences resulted from hereditary factors
- Parental care that is misdirected to
non-offspring (suckling the wrong
baby) and killing of young by
non-parents are the biggest costs
in this category
- dispersal appears to be the prenatal
effects of testosterone on the male embryo during development
and the attainment of critical body mass after birth.
5 True/False questions
Cooperative Rearing of Young in Carnivores (Meerkat) → In mongooses and meerkats, subordinate females help rear the young of the dominant females.
Hamadryas Baboon Natal dispersal → hamadryas baboon males usually leave the natal group around sexual maturation. They usually transfer to a neighboring group with age peers or brothers. Several years later,
they may again transfer to a third group. This pattern of nonrandom
followed by random movement minimizes the chances of mating with kin
Increased Intraspecific Competition for Resources → Agonistic behavior per individual increases as group size increases Foraging per day increases as a function of group size
Lion Dispersal Pattern → 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.
Requirements for piloting → requires a mental map of
the terrain but does not require a compass. In principal it could be
used for longer trips
