The Department of Agriculture is proposing to introduce a host-specific seed-feeding beetle into Australia to control a noxious weed. What factors might limit the distribution of the beetle in Australia? How might you predict its potential geographical range in Australia?. Ecology

What factors would limit the introduced beetle's distribution in Australia

  • Being host specific
  • Synchronous with the pest
  • Specific environmental ranges such as:

o Temperature

o Humidity

o Altitude

o Water availability

A good predictor of the geographical range of the introduced species would be the geographical range in the native habitat.
