  2. “The statistical distributions of the counts of organisms are generally skewed, and hence not normally distributed, nor are variances constant across treatments“

  3. “Techniques to measure abundance of biological or-ganisms vary from simple presence/absence data to estimates of relative abundance, density, or population size.” • “The specific technique used depends on the questions being asked, the most efficient technique to answer a given question, and the biological or logistical constraints that limit the use of each technique “

  4. La distribución negativa binomial • Distribución discreta • Basada en conteos..número de éxitos en una secuencia de pruebas con un número de fallas r predeterminado La línea amarilla es la media La línea verde es la desviación estándar

  5. The parameter m is the arithmetic mean (expected value of x) and thus measures location. The parameter k measures the dispersion of the distribution.

  6. Diferencias significativas
