“…Each of these relict forests tends to have its own suite of endemic species in plant groups (Gentry, 1992;Cano & Valencia, 1992) such as the Solanaceae (e.g., Leiva, 1996;Leiva et al, 1998a;1998b;1998c;1998d;Leiva & Mione, 1999;Leiva & Quipuscoa, 1998), Asteraceae (e.g., Sagasteguii & Dillon, 2001;Sagasteguii & Quipuscoa, 1998;Sánchez & Dillon, 2000) and Loasaceae (Dostert & Weigend, 1999;Rodríguez & Weigend, 1999;Weigend & Rodríguez, 2003;Weigend et al, 1998;2004a;Weigend, 2000a;2000b;, and Alstoemeriaceae-Bomarea (Hofreiter & Rodríguez, infra) but also in many animal groups (Dillon & Cadle, 1991;Duellman, 1979;Duellman & Pramuk, 1999;Cadle & Chuna, 1994;Cadle & Mc Diarmid, 1990, Franke, 1992Salinas et al, 2003). Flanagan et al (infra) provide an overview over the avifauna of the relict forests of NW Peru and show the exceptional wealth of the forests of Ayavaca underscoring the importance of these forest fragments for bird life.…”

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 hábitats con poca dinámica radica en su compleja diversidad florística y endemismos, consecuencia de su complicada topografía y ecología de sus hábitats. En este artículo introductorio se analizan 12 trabajos de investigación expuestos en el Taller sobre Bosques Relictos de la Vertiente Occidental Andina del Norte del Perú y Sur del Ecuador en mayo del 2004 en el X CONABOT, Trujillo-Perú. Aquí, los conocimientos sobre el tema son consolidados y actualizados, es así que los fragmentos de bosque suman más de 20 en el norte del Perú, enfatizando a dos de gran importancia: Bosque La Oscurana (Cajamarca) y Kañaris (Lambayeque). Así mismo, se determinan las relaciones entre los bosques relictos, analiza su dinámica, caracterización y como puede lograrse su conservación inmediata. Se plantean los aspectos cruciales para alcanzar la conservación de estos bosques remanentes: investigar y mostrar urgentemente su gran biodiversidad, subrayar el valor económico potencial de la fitodiversidad que poseen para la región y revalora su papel como áreas de captación de agua para los ríos que son fuente prioritaria para la agricultura y vida urbana en la costa. Palabras clave: bosques montanos relictos, Andes, vertiente occidental andina, Perú, Ecuador AbstractThe forest fragments or relict forests on the Western slopes of the Andes in northwest Peru and in south-west Ecuador are fragile ecosystems, which were largely continuous at some stage in the past. The importance and uniqueness of these forests as «refuges» and stable habitats roots partly in their complex diversity and their high levels of endemicity. These in turn are the outcome of a complex topography and ecology. In this introductory chapter 12 studies are analysed, which were presented at the Taller sobre Bosques Relictos de la Vertiente Occidental Andina del Norte del Perú y Sur del Ecuador in May 2004 at the X CONABOT, Trujillo-Perú. This helps to consolidate and update our knowledge on these over 20 forests fragments in northern Peru and two previously unknown fragments are presented for the first time: Bosque La Oscurana (Cajamarca) and Kañaris (Lambayeque). Some ideas are exposed on the the relationships between the relict forests, how to analyse their dynamics, how to characterize their structure and how their conservation may be achieved. It is proposed that crucial elements in a conservation of these forests are a) urgently inventorizing them to demonstrate their high diversity b) emphasizing their economic potential with respect to the abundance of phytogenet...

Metabolomics is emerging as an effective approach for the comprehensive evaluation of medicinal plants, classification of raw material, as well as chemotaxonomic studies. This work demonstrates the applicability of metabolomics, using the subfamily Barnadesioideae (Asteraceae) as a study model, for quality assessment and classification purposes of medicinal species (Chuquiraga genus) and a chemotaxonomy study of six Barnadesioideae genera (Arnaldoa, Barnadesia, Chuquiraga, Dasyphyllum, Fulcaldea and Schlechtendalia). First, the LC-MS metabolic profiles of Barnadesioideae demonstrated that this subfamily constitutes a chemically underinvestigated taxa with a complex diversity of phenolic compounds, phenylpropanoid derivatives, alkyl glycosides, and triterpenoid glycosides. The intergeneric relationships within Barnadesioideae genera, based on the comparison of their LC-MS metabolic profiles by exploratory and supervised analyses, displayed similarities to those of the intergeneric relationships obtained by the most recent phylogenetic study based on morphological and molecular markers. Second, the LC-MS metabolic profiles of three Chuquiraga species (C. jussieui, C. spinosa and C. weberbaueri) lead to the identification of a significant variety of phenolic compounds, phenylpropanoid derivatives, alkyl glycosides, and triterpenoid glycosides, as well as the establishment of prediction models for geographical origin and species classification, as well as the identification of discriminating metabolites by exploratory and supervised multivariate statistical analysis. Third, a classical approach was carried out by acquiring HPLC chromatographic profiles of three Chuquiraga species (C. jussieui, C. spinosa and C. weberbaueri) for profiling phenolic compounds and comparison by exploratory and supervised multivariate statistical analysis. Therefore, our results support metabolomics as a valuable tool in the quality control and classification of medicinal plants as well as in chemotaxonomy studies.
