    Dendrochronological studies in the Peruvian north coast relate to ENSO
    (Instituto Geofísico del Perú, 2000) Rodríguez, R.; Mabres, A.; Flores, L.A.; Woodman Pollitt, Ronald Francisco
    Dendrochronological studies in the peruvian nort coast to find records of past El Niño - Southern Oscillation (ENSO) events began an the ale 80's. The peruvian north coast is the west-most area of South America, close to equator (05o S 80o W) and to the Sechura desert, is a very sensitive area to the climatic changes due to ENSO. An initial selection of several regional trees have been done for study. The study includes phenological observations and tree ring characteristics analysis as well as racial growth control of tree trunks and branches. The species more intensively studied and suitable to fina records due to the ENSO are Palo Santo, Hualtaco and Sapote.

    Dendrochronological laboratory for studies relate to ENSO events in the tropical zone of South-America
    (Instituto Geofísico del Perú, 1999) Rodriguez, Rodolfo; Mabres, Antonio; Flores, Luis; Woodman Pollitt, Ronald Francisco; Luckman, Brian H.
    The Collaborative Research Network (CRN) project the assessment of present, past and future climate variability in the Americas from freeline environments, currently under development by institutions of Argentina, Bolivia, Canada, Chile and United State. The goal of this CRN project is the recovery of tree-ring records of past climate from freelines sits along the cordillera between Alaska and Tierra del Fuego. It will be used to reconstruct the major made of interhemispheric climate variability for the past centuries free-ring reconstruction of precipitation and temperature will allow delailed study of local and regional climate variability, how it changes with latitude and is linked to the major elements of ocean and global circulation, through a proposal to the program to expand capacity in the Americas (PESCA) of inter-American Institute for Global change Research (IAI) a very and critical area of South-America has been incorporate to such as studies.
