Morphometric study of the differentiation in Acacia bonariensis and Acacia caven var. caven (Fabaceae) in two biological reserves

Background and aims: The genus Acacia has a pantropical distribution and currently consists in approximately 1.450 species throughout the world. In Argentina the species belong to two subgenera: Acacia and Aculeiferum. In this work the morphology of two species was studied, one belonging to the firs...

description Background and aims: The genus Acacia has a pantropical distribution and currently consists in approximately 1.450 species throughout the world. In Argentina the species belong to two subgenera: Acacia and Aculeiferum. In this work the morphology of two species was studied, one belonging to the first subgenus, Acacia caven var. caven and Acacia bonariensis, corresponding to the second one. The aim of this study was to evaluate the interspecific and intraspecific variation based on 12 exomorphological traits. The hypothesis was that the selected traits were able to differentiate species and populations.  M&M: The study was based on the Kruskal Wallis test and several analyses with multivariate methods.  Results: The Kruskal Wallis test found that nine characters were able to differentiate the species and one the populations. From the multivariate analyses the result was that, except for one character, the remaining ones were significant for the interspecific differentiation.  Conclusions: This showed a clear separation between species according to the taxonomic classification already established. However, no differences between reserves could be evidenced for either of the species with these methods. In conclusion, these analyses set a precedent for future studies including more natural populations and the genetic study of the differentiation at molecular level.

En Argentina se pueden encontrar especies pertenecientes a los subgéneros Acacia y Aculeiferum. En este trabajo se estudió la morfología de dos especies, Acacia caven var. caven¸ perteneciente al primer subgénero y Acacia bonariensis, correspondiente al segundo subgénero. El objetivo fue evaluar la variación interespecífica e intraespecífica en base a 12 caracteres exomorfológicos. La hipótesis de trabajo fue que los rasgos utilizados son capaces de diferenciar las especies y las poblaciones.  M&M: El estudio se basó en un test de Kruskal Wallis y en diversos análisis con métodos multivariados.  Resultados: El test de Kruskal Wallis mostró que nueve caracteres fueron capaces de diferenciar las especies y uno solo las poblaciones. A partir de los análisis multivariados se encontró que, a excepción de un carácter, todos los demás rasgos estudiados resultaron significativos para la diferenciación interespecífica.  Conclusiones: Estos resultados evidenciaron una clara separación entre especies de acuerdo a la clasificación taxonómica ya establecida. Sin embargo, no se pudieron establecer diferencias entre los sitios de colección (reservas) para ninguna de las dos especies con estos métodos. En conclusión, estos análisis sientan un precedente para futuros estudios en donde se incluyan más poblaciones naturales y el estudio genético de ésta diferenciación a nivel molecular.
