The taxonomic status of Porites sverdrupi, an endemic coral of the Gulf of California

 Porites sverdrupi has long been considered to be an ecotype of the more abundant and widespread species P. panamensis, but multivariate comparisons of corallite characteristics indicate that P. sverdrupi is morphologically distinct and thus represents a valid species. In these analyses, li...

In these analyses, linear measurements and counts were made on 72 colonies of the two species (53 of P. panamensis and 19 of P. sverdrupi), and analyzed multivariately using canonical discriminant analysis. Generally, corallite characteristics of P. sverdrupi are larger in size than P. panamensis. Important characters in the discriminant function (e.g., number of bifurcate septa, wall thickness, and dorsal septum length) have not been recognized in previous studies of Porites in either the Indo-Pacific or Atlantic regions as being significant in distinguishing among poritid species. In addition to corallite characteristics, P. sverdrupi is unique in its ecological habit, colony form, and geographic distribution. Desde mediados del siglo pasado Porites sverdrupi ha sido considerado como ecotipo y, por consiguiente, sinónimo de otra especie muy abundante y de amplia distribución, P. panamensis. Sin embargo, comparaciones morfométricas a nivel corallite demuestran que las colonias de P. sverdrupi son morfológicamente distintas y por lo tanto ésta constituye una especie válida. En este análisis se contaron o midieron 16 caracteres morfológicos en 72 colonias (53 de P. panamensis y 19 de P. sverdrupi) y luego fueron sometidos a un análisis discriminante. Generalmente las estructuras medidas en ambas especies se encuentran mejor desarrolladas en P. sverdrupi que en P. panamensis. Varios de los caracteres con mayor peso en las funciones discriminantes (e.g., número de septos bifurcados, amplitud de la pared del corallite y longitud del septo dorsal) no habían sido previamente identificados como importantes, ni en el Indo-Pacífico ni en la región del Atlántico, para el reconocimiento de especies de Porites. Además de las diferencias a nivel corallite entre ambas especies, P. sverdrupi es única en sus características ecológicas, forma colonial y distribución geográfica.
