  1. Concept of re wilding
    • -Serengeti 
    • -concept of bringing back things like bison, wolves, bobcats, mountain lions to the great plains
    • -all of the things that Lewis and Clark would have found in there trips across the US
    • -bringing back animals that were extinct long before lewis and clark
  2. Why would you not want to bring animals back that are extinct?
    • -It will mess up the balance again
    • -you cant balance the ecosystem after an animal has died off
  3. Types of Biological corridors

    • • For people this is horrible but for animals seem to sense where the bombs are and can avoid them
    • • They are not getting blown up and the people don’t want to go where these bombs are so they are not disturbing animals
    • • WHOLE vast region where people really haven’t been going a very long time
    • • As a result all the destruction that occurred during the world war is allowing the animals to recover and be more bio diverse
    • • More scientists are willing to go in now and we are discovering these animals
    • • FOR THE TIME BEING it is very interesting in that all of this weaponry and destruction is there but its to the advantage of thewildlife
  38. Mekong River
    • • River and Delta is 12 longest in the world
    • • lot of political problems

    • • Affects LAOS which is all the way at the bottom and affect wildlife
    • • Mekong is important = because it has higher biodiversity per unit of measure compared to the AMAZON
  39. FINDING NEW SPECIES in MEKONG RIVER
    • • Giant carp, Stingrays (7 ft by 7 ft)
    • • Giant Sea Lice
    • • Damming risks all of these fish

  51. Hyrax
    • o Amazing spines that help them flex their way up the trees.
    • o Improving grip as well these Hyrax hang out in trees all day

  58. Flying Squirrel
    • • Can fly up to 50 feet perfectly
    • • Should be called glider squirrels though
    • • They are not territorial and forage together

    • • Not agile enough to hide from birds of prey so they sleep all day in holes and come out at night
    • • The shoulder, hand, fingers all changed dramatically due to adaptation,
  59. Fruit bats of Australia
    • • Have developed true power flight
    • • So big that they cant roost in holes and sleep out at in open
    • • They use their hooked claw to hang out in branches
    • • As fruit bat chooses its perch, it goes into glide and hooks the branch
    • • Wings need delicate grooming and the wing membrane is the fastest growing out of all mammalian tissues

    • • They also snatch them as they hang from branches
  60. Southern Indian Monkey
    • • Lorris
    • • Have elongated thumbs and loss their index fingers

    • • With long reach, and gripping they can cross from one tree to another easily
    • • Live in small groups of 4 to 5
    • • Pee on hands to mark territory and maybe for better grip
    • • Its eyes are placed in a way so it can judge distance with accuracy
    • • Gripping feet and balancing tails leave hands free for the kill
  61. Lesser Bush Baby
    • -Africa 
    • • Only comes out at night
    • • They have a regular pathway they mark with their urine

    • -can eat poisonous stuff
    • -Madagascar plants protect themselves in many ways
    • • Eat plants with spikes
    •  -lemurs are good at eating these still though
    • • Jump from trunk to trunk and only in slow motion can you see how accurately they land
    • • jump around trees like nothing
    • • Feet used as shock absorbers
    • • There back feet are flat and enormous toe so they can latch on to trunk as soon as they hit it
    • • A female can do all that crap even while carrying a baby
    • • Main enemy is the fossa
  63. Fossa
    • -like a giant mongoose 
    • • Four footed runner and a close match in speed

    • • Fossa has adaptation to come down trees with toes pointed down and could come down trees very neatly and easily
  64. Gibbons
    • -not monkeys but small apes 
    • • Around 40 feet jumping distance and can move at amazing speeds
    • • They can also change direction in mid swing
    • • Ball and socket joints that allows them to preform these amazing aerial gymnastics
    • • There unique wrist joint enables them to rotate the body around the hand and not the shoulder
    • -this saves a lot of energy’
  65. HOW OFTEN DO THESE ANIMALS FALL?
    • • Every animal other than birds even bird sometimes have issues
    • • Every animal that doesn't have wings that relies on leaping from great height from tree to tree over a distance, or even if they use tails to balance on to something
    • • They will lean out and go on end of branch, the branch could break and life in forests is a very risky lifestyle
    • • If you become injured nature is cruel and you will probably die and this will impact their ability to climb in the forest
    • -wont be able to run away
