Grassland notes: Notes on world's grassland types & organisms' adaptations to surviving there, including symbiotic relationships with video links

  1. 1. Grasslands PPt. by, Robin D. Seamon
  2. 2. <ul><li>Other words for grasslands: </li></ul><ul><li>Plains: means flat land </li></ul><ul><li>Prairies: N. America </li></ul><ul><li>Steppes: N. America </li></ul><ul><li>Savanna: Africa </li></ul><ul><li>Pampas: South America </li></ul><ul><li>Campos: South America </li></ul><ul><li>Veldts (veld): South Africa </li></ul>
  3. 3. <ul><li>Animal Relationships: </li></ul><ul><li>Symbiosis- a relationship between two different kinds of animals that lasts over time </li></ul><ul><li>Commensalism : a symbiotic relationship where one animal benefits & the other is unaffected </li></ul><ul><li>Parasitism : a symbiotic relationship where one animal benefits & the other is harmed </li></ul><ul><li>Mutualism: a symbiotic relationship where both animals benefit </li></ul>ADVANCE
  4. 4. <ul><li>COMMENSALISM: </li></ul><ul><li>Hyena/vulture & lion: lion kills his meal, this leaves food for scavengers </li></ul>Hyena/vulture Benefits: gets food lion Not affected BACK
  5. 5. <ul><li>MUTUALISM: </li></ul><ul><li>Non-toxic acacia trees & ants most acacia trees have toxic thorns. Some that do not, have ant defenders! The ants are nourished by sugar-water produced by the tree just for the ant & the ant viciously attacks anything trying to feed from its host plant! </li></ul>Acacia tree Benefits: no herbivores ants Benefits: no herbivores BACK
  6. 6. <ul><li>PARASITISM: </li></ul><ul><li>Cowbird & other grassland birds brown-headed cowbird is a notorious brood parasite. It will lay its eggs in another bird’s nest so that the other bird will hatch & raise its chicks. </li></ul>cowbird Benefits: its eggs get hatched & raised Other bird Hurts: its eggs get ruined BACK
  7. 7. <ul><li>Grassy, windy, partly dry, “sea of grass” </li></ul><ul><li>Between dry, arid land and warm, humid land (Usually separates deserts from forests) </li></ul><ul><li>Deep-rooted grasses, few trees and shrubs </li></ul><ul><li>TWO TYPES: </li></ul><ul><li>Tropical grasslands : hot all year with a wet and dry season (savannas) closer to equator </li></ul><ul><li>Temperate grasslands : hot summers, cold winters, higher than equator </li></ul>
  8. 8. Tropical grassland: (savannah) Africa 3 Surviving savanna predators 2Survival in the savanna 4 Survival in the S: shelter Surviving Mosquitos
  9. 9. Temperate grassland: (prairies, pampas) North America
  10. 10. <ul><li>Grasslands may also be divided into these two groups: </li></ul><ul><li>Steppes: short grasses, more dry, hot summer, cold winters (Great Plains of US), dust storms (Dust Bowl from overgrazing, plowing, wind) </li></ul><ul><li>Savannah: tropical grasland, dry season & wet (monsoon) season, less season change, shrubs & small trees, grasses (Australia, India, S. America, Africa) --watering holes </li></ul>
  11. 11. <ul><li>Plants : grasses, sm. trees & shrubs, palms, acacias, boab tree </li></ul><ul><li>Animals : </li></ul><ul><li>hyenas, antelope, zebra, gazelle, lion, rodent, bird, reptile, cheetah </li></ul>
  12. 12. Savanna Plants Boab tree Acacia tree Palms
  13. 13. Savanna Animals:
  14. 14. <ul><li>Prairies: tall grasses, more humid, </li></ul><ul><li>hot summers(100degrees F) </li></ul><ul><li>cold winters (-40degrees F) </li></ul><ul><li>(US midwest- fields of corn, wheat, </li></ul><ul><li>“ sea of grass” </li></ul><ul><li>veld -S.Africa </li></ul><ul><li>pampas - Argentina </li></ul><ul><li>Plants : grasses, flowers </li></ul><ul><li>Animals : coyote, fox, skunk, badger, hawk, </li></ul><ul><li>snake, grasshoppers, insects, field birds, </li></ul><ul><li>prairie chicken, prairie dog, bison </li></ul>
  15. 15. Prairie Plants
  16. 16. Prairie Animals:
  17. 17. <ul><li>Animal Adaptations: </li></ul><ul><li>Animals have adapted to dry, windy conditions </li></ul><ul><li>Grazing animals (eat grass) </li></ul><ul><li>Browser animals (eat leaves & twigs) </li></ul><ul><li>Burrowing animals </li></ul><ul><li>Predators </li></ul><ul><li>Insects </li></ul><ul><li>Savannahs: watering holes </li></ul>
