Describe how the size of the quadrant would impact population estimates what limitations do you think exist for selecting quadrant size for field biologist

The techniques used in population depends on the type of ecosystem. These include the use of traps/footprints, the use of Quadrant, lincoln index and phitographic techniques among others.

Explanation: Using a quadrant method, the population size is given as

N = (Area of sites x total number of individuals) ÷ (Area of the Quadrant x number of throws)

To use this, the area of the sites must have the same unit as the area of the Quadrant. It is used for actively mobile organisms and in a grassland ecosystem. Organisms within the quadrant will be counted.

The limitations are;

It is not suitable for slant topography.

It is not suitable for non-uniform vegetation.

it takes hundreds of years to become stable.

if you have another question lmk.

correct answer: understand the different control methods available

integrated pest management is an strategy that is based on the ecosystem and try to prevent the pest and the damage caused by them by applying combination of technique like habitat manipulation, biological control and use of resistant varieties.

the main aim of the integrated pest management is not to completely eliminate the pest but to strengthen the ecosystem so that conditions are favorable for plants and unfavorable for pests.
