Bio Koala Powerpoint 2

  1. 1. Phascolarctos Cenereus Ella Hubley Koalas
  2. 2. <ul><li>Scientific name- phascolarctos cenereus “ash colored bear” </li></ul><ul><li>Fossils trace back 50,000 years ago--giant koalas </li></ul><ul><li>Europeans fur trade-almost extinct </li></ul><ul><li>Today, live on the coastal southern eastern region--New South Whales, Queensland, Victoria, South Australia </li></ul><ul><li>Now, “protected species”--suffers loss habitat and diseases such as Chlamydia(dieback, brushfires, drought,land clearing) </li></ul><ul><li>Extinction in Victoria-authorities relocate animals--increases numbers--inbreeding and over population occurs </li></ul>
  3. 4. Taxonomy <ul><li>Kingdom: animalia
 </li></ul><ul><li>Phylum: Chordata (spinal chord)
 </li></ul><ul><li>Sub-phylum: Verbrata (backbone) </li></ul><ul><li>
 Class: Mammalia (feeds off memory gland/fur)
 </li></ul><ul><li>Sub-class: Marsupial (saftey pouch)
 </li></ul><ul><li>Order: Diprotodontia (sharp teeth lower jaw/ digits are together)
 </li></ul><ul><li>Sub Order: Vambatiformes( womabat left 2 of 7 known families)
 </li></ul><ul><li>Family: Phascolarctidae (only one left)
 </li></ul><ul><li>Sub Species- not identified as valid. Differ in states characterisitcs.North vs. South </li></ul>
  4. 6. Characteristics <ul><li>Herbivorous, arboreal,marsupial </li></ul><ul><li>-well adapted to life in trees--do not external tails--well balanced </li></ul><ul><li>Lean and muscular--strong limbs--low thigh to shin </li></ul><ul><li>Rough padded paws--five digits sharp claws--front 2 and 3--hind 1 and 4, two attached for grooming </li></ul>
  5. 8. <ul><li>Fur-”raincoat”--woolly protection from extreme high and low temp. very thick and dense “cushion” </li></ul><ul><li>Mature males-brown scent gland </li></ul><ul><li>Individual fingerprints </li></ul><ul><li>Teeth-adapted to herbivorous diet--front cut--molars shear and chew--large diastema </li></ul><ul><li>Average size of a Queensland male- “buck” 14lbs-female “doe”-11lbs--24-33 in. </li></ul><ul><li>Keen sense--tell whose marked territory and toxicity </li></ul>
  6. 9. <ul><li>Small brains-use less energy-adaptive quality to survive on low energy </li></ul><ul><li>Low body temperature--36 degrees Celsius,slow metabolism. </li></ul><ul><li>In temperatures above 77 degrees Ferenheit-use evaporative cooling-breathing rapidly-reduce water loss by the amount of water in their urine-in cold-shiver </li></ul>
  7. 10. Behavior <ul><li>Solitary animals-other than breeding season </li></ul><ul><li>Adults occupy home ranges-range size depends on environment and social ranking--as little as 2.5 acres-half for a female--male live in only 12 diff. trees throughout life </li></ul><ul><li>Dominant male overlap ranges </li></ul><ul><li>Within a stable social group- “food trees” “home trees”--trespassers attacked </li></ul><ul><li>Young koala becomes sexually mature-disperse from mother’s home range </li></ul>
  8. 11. Arnie’s home range-43 acres-travel in a single night during breeding season.
  9. 12. Communication <ul><li>Males bellow--large distances--saves energy--social and physical position </li></ul><ul><li>Females not as often-aggression/sexual behavior--with babies annoyance </li></ul><ul><li>Both have same call- cry when feared or under stress </li></ul>
  10. 13. DIET <ul><li>Eucalyptus leaves contain approximately 50% water, 18% fibre, 13% tannins, 8% fat, 5% carbohydrates, 4% protein and 2% minerals. </li></ul><ul><li>Contains cellulose-inedible </li></ul><ul><li>Large caecum </li></ul><ul><li>Digestive system-water loss </li></ul>
  11. 15. BIRTH <ul><li>Marsupial--live in pouch 6 to 7 months </li></ul><ul><li>Rides on back </li></ul><ul><li>Pap--in order to get the right digestive system for eucalyptus leaves </li></ul>
  12. 18. Chlamydia <ul><li>Most healthy koalas have antibodies--will not necessarily die </li></ul><ul><li>Transmitted through pap, mating, fighting </li></ul><ul><li>Could be natural selection? </li></ul><ul><li>Prevents trees from being over browsed </li></ul>
  13. 19. Bibliography <ul><li>(“ANTARCTICA YIELDS FIRST LAND MAMMAL FOSSIL”By ROBERT REINHOLD, SPECIAL TO THE NEW YORK TIMES Published: March 21, 1982) </li></ul><ul><li>(“Environmental assessment of koala’s conservation status, Australian Government website: www.environment. gov . au/minister/env ) </li></ul><ul><li>.
