Abstract
El cambio climatico antropogenico es una de las principales causas de perdida de la biodiversidad. En este contexto, existe la necesidad de estudios basados en los futuros impactos del cambio climatico de gran escala para proponer estrategias de conservacion de especies en peligro de extincion como es el caso de Puya raimondii Harms, una especie de bromelia endemica de los Andes de Peru y Bolivia. En este articulo, nosotros modelamos la distribucion potencial actual y futura de P. raimondii con la finalidad de identificar areas prioritarias para la futura conservacion de esta especie endemica. Nuestros resultados revelaron que 1) los espacios actuales potencialmente apropiadas estan centrados para los andes de Peru y Bolivia con una extension de 154268.40 km2, y 2) en escenarios futuros de cambio climatico para la decada de 2070, hay una perdida de areas potenciales, viendose una reduccion de promedio de area a -34326.53 km2 y -8193.22 km2 para los dos escenarios climaticos de las vias de concentracion representativas (RCP) 4.5 y RCP 8.5 respectivamente. Estos resultados sugieren que a escenarios de cambio climatico solo cinco parches de habitat seran idoneos para albergar a P. raimondii , por tanto, proponemos que las medidas de conservacion deben ser priorizadas a dichas areas.

In this context, there is a need for studies based on the future impacts of large-scale climate change to propose conservation strategies for endangered species such as Puya raimondii Harms, a species of bromeliad endemic to the Andes of Peru and Bolivia. In this article, we model the current and future potential distribution of P. raimondii in order to identify priority areas for the future conservation of this endemic species. Our results revealed that 1) the current potentially suitable areas are centered in the Andes of Peru and Bolivia with an extension of 154268.40 km 2 , and 2) in future climate change scenarios for the 2070s, there is a loss of potential areas, with an average reduction of area to -34326.53 km 2 and -8193.22 km 2 for the two climate scenarios of Representative Concentration Pathways (RCP) 4.5 and RCP 8.5 respectively.
