Esparza Olguín Javier Valle-Mora Biología cafeto forofito micrositio árbol de sombra estadíos de vida We studied the population structure of Oncidium poikilostalix (Kraenzl.) M.W. Chase & N.H. Williams (Orchidaceae) newly reported for México in 2008 in the region of Soconusco (Chiapas state) in southeast Mexico, growing in shaded coffee plantations in two rural communities, Fracción Montecristo (FM) and Benito Juárez El Plan (BJ). In 2008-2009, we determined the characteristics of these coffee plantations, and the distribution of the various life stages (seedling, juvenile, adult) on the two phorophytes: coffee bushes (Coffea arabica L.)and shade trees (Ingamicheliana Harms.). Principal Component Analysis and Discrimination Analysis were used to compare all the variables evaluated. There were 1123 individuals (82.63%) in FM and 236 (17.37%) in BJ. Of those, in FM 1060 individuals (94.4%) were epiphytic upon coffee bushes and 214 (91.06%) in BJ, the rest were epiphytic upon the shade trees (I.micheliana). Despite displaying the characteristics of a twig epiphyte, the preferred microsites of O. poikilostalix were the branches of the coffee bushes, with 703 individuals (55.18%) and the trunk of the shade trees, with 78 individuals (91.76%). More than a third of the population was juvenile stage (37.09%; 504 individuals). Oncidium poikilostalix probably entered México from Guatemala and appears to be a vigorous plant that is successfully adapting to its new sites of occupancy 2011 artículo científico 1409-3871 https://www.redalyc.org/articulo.oa?id=44339820004 en http://www.redalyc.org/revista.oa?id=443 Lankesteriana International Journal on Orchidology application/pdf Universidad de Costa Rica Lankesteriana International Journal on Orchidology (Costa Rica) Num.1 Vol.11 |
