Abstract: Bosques relictos del NO de Perú y SO de Ecuador Weigend, Rodríguez y Arana (Comps.) Rev. peru. biol. 12(2): 185 -194 (2005) http://sisbib.unmsm.edu.pe/BVRevistas/biologia/biologiaNEW.htm The relict forests of Northwest Peru and Southwest Ecuador ResumenLos bosques relictos o fragmentos de bosque en las vertientes andinas Noroccidentales del Perú y Suroccidentales de Ecuador, son frágiles ecosistemas, que en el pasado fue un todo continuo. La importancia y singularidad de los bosques como «refugios» y hábit… Show more

“…In their entirety, the páramos that extend from Costa Rica to northern Peru cover a total area of 33,978 km 2 , of which Ecuador (12,603 km 2 ) occupies the second position after Colombia (Hofstede, 2003). The Andean páramos are home to the most abundant floristic richness among the tropical mountains due to their special historic, geological, geographical -including the phenomenon of insularity -, climatic and anthropic characteristics (Simpson, 1974;Vuilleumier & Monasterio, 1986;Smith & Cleff, 1988;Luteyn, 1992;Jørgensen & Ulloa, 1994;Hofstede & Rossenaar, 1995;Ramsay & Oxley, 1997;Richter & Moreira-Muñoz, 2005;Weigend et al, 2005;Coblenz & Keating, 2008;Josse et al, 2008;Richter et al, 2009;Madriñán et al, 2013;Sklenář et al, 2014;Vázquez et al, 2015). In regard to the flora of the páramo, Luteyn (1999) indicated a total of 447 genera and 3045 species from Costa Rica to Peru; and Sklenář et al (2011) subsequently reported 509 genera and 3564 species, while Rangel-Churío (2000) calculated a total of 566 genera and 3173 species.…”

“…Con el levantamiento de las Cordilleras Diversidad y distribución de los endemismos de Asteraceae (Compositae) en la Flora del Ecuador Occidental y Oriental de los Andes y el fin de las irrupciones marinas desde el Mioceno nuevas rutas migratorias quedaron establecidas y la Cordillera Andina quedó interconectada (Antonelli & Sanmartín, 2011). Prueba de ello son los bosques relictos o fragmentos de bosque con gran riqueza florística y de endemismos en la vertiente occidental del norte de Perú y del sur de Ecuador que en el pasado constituyó una unidad (Weigend et al, 2005).…”

“…Esta depresión sigue actuando como una barrera geográfica natural entre los Andes del Norte y los Centrales, que contribuye a la especiación al perderse la continuidad en la cobertura forestal (Weigend et al, 2005). Un ejemplo de ello es el valle árido del Río Santa en la zona Amotape-Huancabamba en Perú, fronteriza con Ecuador (Weigend et al, 2005).…”

“…Since its discovery in 1997, Xylopodia klaprothioides (Fig. 2 ) has been considered a rare paleoendemic, that survived only in a single spot on the western Andean slope in northern Peru, part of the so-called Amotape-Huancabamba-Zone, a region of extraordinary species-richness including many old relic species, disjuncts and massive recent radiations ( Weigend 2002 , 2004b ; Weigend et al 2005 ; Mutke and Weigend 2017 ). However, recent field studies by one of us (CM) have led to the discovery of plants that can be clearly assigned to the genus Xylopodia in Argentina, Prov.…”
