Registered author(s):

    El riesgo de extinción de una especie se estima por la evaluación del estado de deterioro de la población. Una especie silvestre y no extinta puede ser evaluada y clasificada como: En Peligro Crítico, En Peligro, Vulnerable, Cuasiamenazada, de Preocupación Menor. En Colombia se ha realizado esta clasificación para algunos grupos de fauna y flora. En este trabajo se utiliza la información de la Serie Libros Rojos de Especies Amenazadas de Colombia (Reptiles, Peces dulceacuícolas) para calcular el cambio en la probabilidad del riesgo de extinción ante variaciones de variable económicas que describen algún tipo de presión por explotación directa del recurso o modificación del hábitat. La herramienta cuantitativa para el análisis de la información es un modelo de variable dependiente discreta ordenada.
