Primatology Notes #11
Primate ECOLOGY

Primate  Ecology


  • Relations to habitat (habitat use):
    • Home range, day range
    • Core areas, space between (as in baboons; sleeping trees important)
    • Continuous canopy for arboreal species


  • Socioecological models:
    Predation
    pressure    
    Food
    resources    
    Population    
    density
     
    Outcome
    High Dispersed Low  
    "Dispersal-Egalitarian":
          high female dispersal; no coalitions
    High Dispersed High "Resident-Egalitarian":
          in-between previous and next
    High Clumped Low "Resident-Nepotistic":
          strong female social groups (coalitions);
          nepotism; no dispersal
    Low Clumped High Similar to previous, but with contests between groups


  • Miscellaneous:
    • If no threats:   play, sex
    • Reaction to snakes
    • Seed dispersal; seed shadow
    • Bitter leaves and pith: possible anti-helminth, self-medication



    Possible to skip the following until after apes

  • Primate habitat and the Threat of Extinction:
    Threats include:
    • Habitat destruction (incl. mining, agriculture)
    • Poaching-- hard to control in some places
    • Epidemic diseases (e.g., Ebola)
    Extinction risk (AAAS article)
    Extinction risk (NY Times article)
  • Proposed solutions:
    • Stronger law enforcement against poaching, habitat encroachment, mining
    • Forect reserves, national parks
    • Rainforest agriculture   }   Encourages local economy to be
    • Ecotourism                   }   in harmony with conservation goals
    • Captive breeding and reintroduction
