Dendrochronological Network of Mountain Pine (Pinus hartwegii Lindl.) for dendroclimatic studies in Northeastern and Central Mexico
Pinus hartwegii is a high elevation species forming the upper treeline in Mexico- from volcanoes of the Transmexican Volcanic Belt in central Mexico and from high elevation peaks of the Sierra Madre Oriental in northeastern Mexico.

| Sumario: | Pinus hartwegii is a high elevation species forming the upper treeline in Mexico- from volcanoes of the Transmexican Volcanic Belt in central Mexico and from high elevation peaks of the Sierra Madre Oriental in northeastern Mexico. Pure stands of hartwegii pine have been severely logged in the past affecting the proper functioning of the ecosystem, impacting water yield, biodiversity, and other ecosystem services in detriment of the wellbeing of dense human settlements in the Valley of Mexico. In addition to land-use changes, climate warming may threat this ecosystem by altering their health, favoring the recruitment over the treeline where is not adapted, and affecting its dynamics, growth rates, and ecological relationships with associated species. Given the dendrochronological potential of hartwegii pine to produce centuries-long time series useful to analyze high and low frequency climate variability, and influence of atmospheric circulatory patterns, the objective of this study was to develop a network of treering chronologies for central and northeastern Mexico, analyze its potential for dendroclimatic reconstructions and to determine the potential impact and teleconnections of atmospheric circulatory patterns. |
