  1. Many eyes hypothesis
  2. Frugivorous primate colonies
  3. Ranging
  4. Optimum Hunting Size
  5. The grates differences in sex spatial ability is seen in?
  1. a individuals in large groups spend less time watching for predators and more time doing other activities such as eating.
  2. 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.
  3. c polygynous or promiscuous
    mating systems, and especially those with scramble competition
    for mates.
  4. d Optimum group size in lions varies depending on the prey they take - 2 lions in the case of eating Thomson's gazelle.
  5. 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

  1. 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.
  2. 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
  3. Many marine mammal
    strandings have been associated with changes in the earth's
    magnetic field possibly due to solar flares or areas of magnetic
  4. 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
  5. Many species who live in large
    groups have the challenge of
    identifying their young when
    returning from a foraging trip.

5 True/False questions

  1. Station KeepingUsed to be defined by round trip but now one-way travel also counts


  2. Traditiona behavior passed from one generation to the next
    through the process of learning.


  3. Nature vs. Nurture study participantsAfter 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
    innate preference.
    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.


  4. Allee EffectBehavior that is potentially costly to the individual but beneficial to others


  5. Pilotinga process by which most species return to a home range, nest
    site or den
