  1. Bats and Migration
  2. Benefits of Mammals Living In a group
  3. Causes of Dispersal at Proximal Level
  4. Alarm Calling
  5. Frugivorous primate colonies
  1. a an individual may be forced out by its
    parents or as an involuntary response to increased testosterone
    levels associated with sexual maturation
  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 Benefits from Physical factors Protection against Predators Finding and Obtaining food
  4. d When a mammal emits an alarm call, the caller is more likely to fall prey to the predator. The predator might abandon the hunt since they've been detected (caller is selfish) Other individuals may benefit (altruism)
  5. e As the only flying mammals bats might be expected to
    show long distance migrations like birds but that is not generally
    true. Bat wings are very effective for slow maneuverable flight
    but not long distance migrations.

5 Multiple choice questions

  1. Choice of a habitat may be limited by:
    • accessibility (islands versus mainland)
    • behavior patterns (i.e., prefer trees to grasslands)
    • predators
    • parasites
    • diseases
    • allelopathic agents (plant toxins)
    • competitors
    • abiotic factors (temperature, moisture, light, nutrients)
  2. - a sense of direction (some form of compass)
    - a sense of location (understand where it is starting from)
  3. Wolves and lions are able to capture large species of prey - such
    as moose or Cape Buffalo - that would not be possible for individuals.
  4. Populations that have survived episodes of inbreeding in the past
    may tolerate current inbreeding with relatively few ill effects. This is likely because deleterious recessive alleles already have been
    selected out of the population i.e Cheetah
  5. The hippocampus

5 True/False questions

  1. Homingincludes trips outside the
    home range, usually in search of mating opportunities or suitable
    habitat. This type of movement includes natal dispersal.

          

  2. Causes of Dispersal at ultimate levelIn 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.

          

  3. Size of Hippocampus differencesTend to be large and have large brains

          

  4. Natal Dispersal in MammalsMost 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

          

  5. Naked mole rat- a representation of
    the geometric relationships among a home site, terrain surrounding
    the home site, goals to be visited, and the terrain surrounding those
    goals.
