Background and aims: In the semi-arid saline Chaco, Argentina, the nanophanerophytes presence and the succulent leaf type are frequent. To determine if the occurrence of both traits is related to soil salinity, this paper describes the distribution of life forms and leaf types in relation to soil salinity between two woody plant communities.M&M: Sampling of woody plant and soil was carried out in both a scrubland and a xerophilous forest on 25 subplots of 100 m2 at each site. Electrical conductivity and pH were determined on 50 cm deep. Stratification and plant cover, abundance, species richness and diversity index were described. The degree of similarity between sites was evaluated according to the number of nanofanerophyte and succulent-leaves shared species, using the Sørensen coefficient. The species were grouped considering simultaneously their life form and leaf type. Relationships between salinity and plant groups were evaluated by means of redundancy analysis. Results: Richness, diversity and structural complexity were greater in the forest. The similarity between sites was low. Succulent-leafed nanophanerophytes were dominant in the scrubland, with high salinity and pH. In the forest, sclerophyllous–leafed microphanerophytes were dominant, with low salinity and pH. Conclusion: The distribution of succulent-leaves nanophanerophytes presented differences according to the salinity of the soil of both woody communities. |

Introducción y objetivos: En los hábitats salinos del Chaco semiárido es frecuente la forma de vida nanofanerófita y tipo de consistencia de hoja suculenta. Para determinar si la ocurrencia de ambos rasgos está relacionada a la salinidad del suelo, en este trabajo se describe la distribución de formas de vida y tipos de consistencia de hoja en relación a la salinidad del suelo entre dos comunidades leñosas. M&M: Se realizó un censo de leñosas y un muestreo de suelo en un matorral halófilo y en un bosque xerófilo sobre 25 subparcelas de 100 m2 en cada sitio. Se determinó pH y conductividad eléctrica del suelo hasta 50 cm de profundidad. Se describieron la cobertura y estratificación de vegetación, riqueza, abundancia e índice de diversidad para especies leñosas. Se evaluó el grado de similitud entre sitios según la cantidad de especies de nanofanerófita y de hoja suculenta compartidas, mediante el coeficiente de Sørensen. Las especies fueron agrupadas considerando simultáneamente su forma de vida y tipo de consistencia de hoja. La relación entre salinidad y grupos de leñosas se evaluó mediante un análisis de redundancia. Resultados: La riqueza, diversidad y complejidad estructural fueron mayores en el bosque. La similitud entre sitios fue baja. Las nanofanerófitas de hojas suculentas dominaron en el matorral con elevada salinidad y pH. Las microfanerófitas de hojas semi-coriáceas fueron dominantes en el bosque con baja salinidad y pH. Conclusión: La distribución de las nanofanerófitas de hojas suculentas presentó diferencias según la salinidad del suelo de ambas comunidades leñosas.
