Diferencias en el hábito de crecimiento como variable explicativa de la influencia climática en Prosopis flexuosa en el Desierto del Monte Central (Argentina). Piraino, Sergio Roig Juñent, Fidel Alejandro Algarrobo dulce ancho de anillo clima variabilidad intra-especifica. Algarrobo dulce climate intra-specific variability ring width. Tree growth habit differences as an explanatory variable of the climatic influence upon the radial growth variability of Prosopis flexuosa in the Central Monte Desert (Argentina). Dendroclimatological methods represent one of the most useful tools in analyzing the influence of climate upon the radial growth dynamics and morphology of woody species. In the Central Monte Desert, Prosopis flexuosa DC (algarrobo dulce), grows as one-stemmed as well as multi-stemmed tree. Previous researches showed the utility of the species ring widths as a proxy of climate variability. Nevertheless, these researches differed methodologically, by considering or rejecting the multi-stemmed trees. This work analyzed if the variability in the tree growth habit express differences in the algarrobo dulce dendroclimatological signal. Two tree-ring chronologies, one derived from the one-stemmed (UF) and the other from the multi-stemmed trees (MF) growing under the same ecological environment, were developed. The MF chronology showed higher sensibility than the UF to climate extremes and oscillation. This suggested that multi-stemmed trees represent a good proxy for explaining local climatic variability. Due to the widespread spatial distribution of this species, further works are needed to a deeper understanding of the presented results. Los métodos dendroclimatológicos representan una de las herramientas más valiosas para analizar la influencia del clima sobre la dinámica del incremento radial y la morfología de las plantas leñosas. En el Desierto del Monte Central, Prosopis flexuosa DC (algarrobo dulce), crece como árbol uni-fustal pero también como multi-fustal. Investigaciones anteriores han evidenciado la utilidad del ancho de anillo de esta especie como registro de eventos climáticos. Sin embargo, estas investigaciones han diferido metodológicamente, considerando o descartando los individuos multi-fustales. Este trabajo analizó si la variabilidad en el hábito de crecimiento expresa diferencias en la señal dendroclimática del algarrobo dulce. Dos cronologías de ancho de anillos, una derivada de individuos uni-fustales (UF) y otra de multi-fustales (MF) presentes en un mismo ambiente ecológico fueron desarrolladas. Se observó que hay una mayor sensibilidad de la cronología MF respecto de la UF en relación a la incidencia en el crecimiento de eventos climáticos extremos y del clima en general en el largo plazo. Esto sugiere que los individuos multi-fustales constituyen una buena representación de la variabilidad del clima local. Debido a la gran extensión territorial de especie, otros estudios que abarquen la extensión geográfica de P. flexuosa son deseables para profundizar los resultados logrados.
