EVALUACIÓN DE RIQUEZA EN COMUNIDADES MICROBIANAS

  • Cristóbal Santa Maria
  • Marcelo Soria

Resumen

La riqueza de una comunidad microbiana es un importante parámetro para comparar su estructura con otras comunidades a través del  tiempo y  el entorno. La estimación de la riqueza basada en datos de un gen marcador obtenidos por Secuenciación de Nueva Generación presenta diversos problemas estadísticos. Los estimadores habituales, derivados del análisis de macro-organismos, tienden a subestimar la riqueza de comunidades microbianas. Desarrollamos aquí un proceso estocástico para entender los efectos de la estructura de la población sobre las estimaciones tradicionales de riqueza e introducimos el Algoritmo de Recuento de Especies (AQS).
