Science equidae(animal)

  1. 1. EQUIDAE Jenny Lee
  3. 3. FOOD WEB
  5. 5. WHERE DO THEY LIVE?  Zebras and horses mainly live in grasslands, where there is lots of grazing land.  Donkeys live near deserts - they are adapted to the conditions of a desert
  6. 6. COMPETITION?  There is not much competition for zebras, horses, or asses, because they are herbivores and their main food source is grass. Since they live in grasslands, there will be tons of grass available for each animal. Thus, there is not much competition for food.  However, there is competition for mating. Males have large teeth for fighting when mating.
  7. 7. BIODIVERSITY OF EQUIDAE? (WHO ARE THEY RELATED TO?)  They belong to the equine genus Equus: Basically, all the living species of the horse family, which is Equidae, are under one genus, Equus.  Related to tapirs and rhinoceros  Equidae is one of the three families in Perissodactytla. The other two families are tapirs and rhinoceroses.
  8. 8. ADAPTIVE RADIATION?  The specific species have radiated out to adapt to their own environment.
  9. 9. ADAPTATIONS-ZEBRAS  Zebras tend to live in herds, not just with other zebras, but with other animals as well, such as giraffes; living in herds helps them spot predators  They have a unique digestive system that allows them to gain nutrition even from poor quality grass.  Have different types of teeth to suit their food needs  At front, they have strong incisors to use for biting off grass  In the back, they have molars and premolars that help them to chew their food  Zebra also have high-crowned grinding teeth to protect their teeth from wearing down from the silica content in grass.  Male zebras have large canine teeth for fighting  Their stripes provide a “dazzle” camouflage  Instead of hiding, the stripes break up the outline of zebra, causing predators to suffer by making them misjudge the distance when they are hunting zebras.  It also confuses parasitic flies, since the stripes on the zebra are different than other mammals. 
  10. 10. ADAPTATIONS-HORSES  Have eyes on both sides of their head to help them sight predators or any possible dangers  Strong hooves allow them to defend themselves and to run and walk on almost any ground.  Live in herds to maintain warmth and to protect themselves from predators
  11. 11. ADAPTATIONS-ASSES  Since many asses live in the desert, they have digestive tracts that enable them to eat coarse plants, such as bushes and barks.  Have crowned teeth to help them grind silica-containing grass  Their long limbs and narrow hooves allow them to move swiftly and easily  The grey or tan colour of asses provides camouflage in the desert.
  12. 12. EVOLUTION o The evolution of horses occurred over 50 million years
  13. 13. HOW DOES PRIMARY AND SECONDARY SUCCESSION AFFECT EQUIDAE?  For any of the two types of ecological succession, horses, asses, and zebras will need to adapt to a whole new environment. Especially when plant species are altered, there will be limitations for their food sources. Gradually, the equidae will develop new adaptations to accustom themselves to their new environment. Then there will be more adaptive radiations.  Also, with primary succession, it may allow new habitats for the equidae due to the newly established environment.
