Botanica %D 2011 %I Universidad de Concepci¨®n %X Se analiz¨® la distribuci¨®n geogr¨¢fica de 12 especies de cact¨¢ceas incluidas dentro de cinco g¨¦neros utilizando un enfoque panbiogeogr¨¢fico, con el fin de identificar los patrones biogeogr¨¢ficos de este grupo y contribuir al estudio de las relaciones biogeogr¨¢ficas de la flora del Ecuador. Las especies seleccionadas se distribuyen principalmente en los bosques secos del norte de Per¨² y sur del Ecuador. Mediante el an¨¢lisis de trazos, se identificaron tres trazos generalizados (costero seco, interandino del centro-norte e interandino del sur) y un nodo en la confluencia del segundo y tercer trazos a nivel de la provincia biogeogr¨¢fica del Occidente de Ecuador. The geographical distributions of 12 species of Cactaceae assigned to five genera were analyzed using a panbiogeographic approach to identify their biogeographic patterns and contribute to the study of the biogeographical relationships of the flora from Ecuador. The selected species are distributed mainly in the dry forests of northern Peru and southern Ecuador. Based on the track analysis, three generalized tracks (dry coastal, central-northern interandean and southern interandean) and one node were identified, the latter in the overlap of the second and third tracks at the biogeographic province Western Ecuador. %K Cactaceae %K panbiogeograf¨ªa %K trazos generalizados %K bosques secos %K distribuci¨®n %K Cactaceae %K panbiogeography %K generalized tracks %K dry forests %K distribution %U http://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0717-66432011000200013
