• What are methods of studying ecology?

  • Sample and scale up
  • Mark release recapture
  • Random sampling
  • Systematic sampling
  • Simpsons diversity index
• What are continuous transects?

  Transects with no gaps
• What are discontinuous transects?

  Transects with gaps
• What is species diversity?

  The number of individuals within the species
• What is species richness?

  The number of species in an area
• What organisms does mark release recapture measure?

  Fast moving animals
• How do you carry out mark release recapture?

  1. Collect a sample and count them
  2. Mark them and release them
  3. Give them time to reintegrate
  4. Catch a second sample, count the total and the number of marked individuals
• What is the equation for mark release recapture?

  $estimated\ population\ size\ =$$\ \frac{size\ of\ first\ sample\ \times\sec ond\ sample}{number\ of\ marked\ recaptured}$
• What is the calculation for diversity index?

  $D\ =$$\ \frac{N\ \left(N-1\right)}{\sum_{ }^{ }n\left(n-1\right)}$
