VMD 512: Zoo/Wild Animal Breeding, Management, Nutrition and Health Care (1+1)

ECO-SYSTEM

• This is a mosaic of habitat patches. There is a special relationship between the different ecosystems existing in the wildlife regions. There are movements of organisms between different patches in the revolving world.
• It is to be understood that the movements in general occur among the wildlife species or organisms due to many reasons.
  • Movements for establishment of territories
  • Search for feed resources
  • Movement due to water scarcity
  • Movements due to the extreme climatic variations
  • Search for proper shelter
  • Dispersal from areas with high population concentrations to less densely populated regions
  • Pressure from hunting or frequent predator attack
  • Movements due to hazards (acoustic injuries to dolphins, whales and dugongs)
  • Other reasons that are still to be clarified.
