Overview
To assess the completeness of a floristic or faunal inventory, one may use the ratio of the observed number of species to the \"true number\" of species (C). If the inventory is complete, C = 1. The estimate of the true number can be obtained from accumulation curves, nonparametric methods, or other techniques. We devised a simple method for computing confidence intervals (CI) for C and for evaluating the null hypothesis that the inventory is complete. The method is based on the assumptions that an estimate of the variance of the true number of species is known and that the distribution of the estimator of the true number of species is approximately normal. We applied our method to bird inventories in the Balsas Basin of Mexico. The completeness index for subtransects were lower (84.0, 85.4, and 89.9%) than for the whole transect (91.6%) (all significantly different from 100%). Thus, these particular inventories were incomplete at 2 spatial resolutions. Our method of estimating CI for C can be used to estimate species richness obtained from databases of different sites or to test the null hypothesis that an inventory derived from a database is complete. /// Para evaluar la completitud de un inventario florístico o faunístico, se puede utilizar la relación entre el número de especies observadas y el \"número verdadero\" de especies (C). Si el inventario está completo, C = 1. La estimación del número verdadero de especies se puede obtener de curvas de acumulación, métodos no paramétricos u otras técnicas. Diseñamos un método simple para calcular los intervalos de confianza (IC) para C y para evaluar la hipótesis nula de que el inventario está completo. El método se basa en los supuestos de que se conoce una estimación de la varianza del número verdadero de especies y que la distribución de un estimador de la varianza del número verdadero de especies es aproximadamente normal. Aplicamos nuestro método a inventarios de aves de la Cuenca del Balsas en México. El índice de completitud para subtransectos fue menor (84.0, 85.4 y 89.9%) que para el transecto completo (91.6%) (todos significativamente menores a 100%). Por lo tanto, estos inventarios en particular fueron incompletos en dos resoluciones espaciales. Nuestro método de estimación de IC para C puede ser utilizado para estimar la riqueza de especies obtenida de bases de datos de diferentes sitios o para probar la hipótesis nula de que un inventario derivado de una base de datos está completo.
