Mark-recapture technique can have drawbacks;

1. Some animals that have been marked may learn to avoid the traps. 
2. Recapture rates will then be low, resulting in an overestimate of population size.

Some animals can become trap-happy, particularly if the traps are baited with food. This would result in an underestimate of the population size.

Clumped: The most common dispersion pattern is clumped, because resources tend to be clustered in nature.

Uniform: Competition may cause a uniform dispersion pattern between individuals. The pattern of trees and seedlings may appear random as seedlings develop from seeds dropped at random.

1. The dispersion pattern starts out random but ends up uniform.
2. Uniform dispersions may also result from social interactions.
3. Territoriality between animals also causes uniform dispersion patterns.

Random: The rarest dispersion pattern is random because resources in nature are rarely randomly spaced.
