  1. Pygmy Tarsier
    • -Oriental realm
    • • Not sure how many left because number is so small
    • • Is smaller than regular tarsier/pretty darn small
    • • Can fit in your hand
    • • Losing habitat because they are in conflict zone and war is never good for any animal at all
    • • Other problem is that they are cute so they become part of the pet trade
  2. Javan Slow Loris
    • -Oriental realm 
    • • Habitat loss, deforestation, pet trade,
    • • Are endangered because of traditional medicine
    • • Something about their teeth
    • • People like to get their teeth, grind them up, and use them for medicinal reasons
  3. Tonkin Snub Nosed Monkey
    • • Not going to make it out of this century
    • • Fewer than a hundred left
    • • Used in traditional medicines as well
    • • BUSH MEAT because it’s a medium body sized animal
    • • Medium and large sized monkeys are used in bush meat trade
    • • Lost habitat due to timber, and cultivation
    • • Live in forest of developing or struggling nations and it really sufor these little guys
  4. Pig Tailed Snub Nosed Monkey Langur
    • -Oriental Realm 
    • • Medium body so again bush meat
    • • 3 other species of Langur that have same basic body structure that are also endangered and on the list
  5. Gray-shanked Douc Monky
    • -Oriental Realm 
    • • Very attractive monkey and thought to be extinct and saw a few but now in trouble again
  6. Eastern Black Crested Gibbon
    • -Oriental Realm 
    • • Is struggling with gene collapse, and not healthy enough to survive as a species anymore
    • • Inbreeding makes them more likely to catch diseases and mutations
  7. San Martin Titi Monkey
    • -Neotropics
    • -Very Popular as pets
    • -considered bush meat
  8. Capuchin monkey
    • -neotropics
    • -used as pets and much thicker fur than other capuchins
  9. Northern Brown Howler
    • -Neotropics 
    • -Shows us these last three so we can understand that an animal can seem very common because you see it all the time, but it is a different species
    • o When an animal divides off and branches off into another species it is frequently that branch that doesn’t have a long population of animals to stir with
    • o Bc of deforestation habitat fragmentation , human encroachment, that is not going to impact just howler monkeys or whatever
    • o They just so happen to be on the list of 25 most endangered primates
  10. Neotropical Realm: Where
    • • South and central America through the Yucatan Peninsula, includes Caribbean islands • All of South America and central America and first third of Mexico,also Cuba and all of the islands.
    • • North -> South orientation is the most important thing for thisrealm
  11. Neotropical: Climate, vegetation
    • • Tropical rainforest
    • • Coast
    • • Desert
    • • Grassland: tropical, temperate, flooded, mountain
    • • Mangrove
    • • Forest = Broadleaf, tropical dry, coniferous
    • • Not like Palearctic that was from East to west the Neotropic you are going from well above the equator to all the way down to 60degrees south
    • • That is a really long way
    • • The realm runs from where there is direct sunlight 12 hours a day to a realm where you only get direct sunlight certain times of theyear
    • • All these lions of latitudes, things are going to change
    • o It can be very cold, to being consistently warm
    • o To a very consistent type of temperature year round
    • o And everything in between ! Which means there a lot of niches and adaptations
  12. Neotropical Realm: Plate Tectonics
    • • Plates go underneath each other
    • • Seduction of plates created Andes and all of this crazy geographic features and niches
    • • Spent a lot of its history as a an island directly after Pangea
    • • All the animals on this land mass were able to develop in same rather unique that animals adapt on an island
    • Then it stopped being island
    • • When strait of panama developed and volcano erupted
    • • It connected south America to North America
    • • This allowed for an exchange of animals
    • • and suddenly now there’s a way to expand north and get off this island
    • • or for other animals to expand south in your territory and perhaps take over your territory and push some animals out of their niche
  13. 5 key things about Neotropics
    • 1. North south
    • 2. Wide range of latitude
    • 3. Strait of panama
    • 4. Was island for a long time
    • 5. Plate tectonics
  14. Great American Biotic Interchange
    • • Lots of animals made it from the north to south
    • • Animals where able to come down to neotropics and establish themselves
    • • The success rate was good for a high percentage of animals (dogs, ungulates, camels, bears)
    • • All came south and did well
  15. Going from South to North
    • o Only two animals to make it from south to north and survive where the porcupines and the opossums
    • o A whole bunch of species tried but didn’t make it. They got there for a little while and couldn’t make it
    • o Something going from south to north was much more difficult
    • o Anything going from North to south and tried to go back northdidn’t make it
  16. Going North to South
    • • Large bodied cats, camels, bears, horses, did well
    • • Horses = started in north America did well south tried to return and didn’t make it
  17. Atlantic Forest
    • o Couple of critically endangered invertebrate species in the area

    • o Its got an interesting sort of situation because although it has fire tolerant plants, it does receive a fair amount of rainfall for 6-7 months of the year
    • o When it is NOT raining it is NOT RAINING (can get extremely dry)

    • o THE LARGEST hot spot in this realm, and third largest hotspot in the world
    • o Unbelievable amount of biodiversity bc of great American biotic interchange
    • o And bc it is relatively new part of the world in grand scheme of things (developed from volcanic activity) lots of niche changes and biodiversity
    • o From Honduras to Panama, every inch of it is a hotspot
    • o 65% of the amphibians and 67% of freshwater fish found in this region are endemic
