- Measuring temporal wood density variation improves carbon capture estimates in Mexican forests Marcos González-Cásares José I. Yerena-Yamallel Marín Pompa-García Multidisciplinarias (Ciencias Sociales) Biomass densitometry Pinus cooperi climate change dendrochronology Knowing carbon (C) content variations in forests, provides information relevant to assess-ing climate change. Traditionally, methods for calculating C content are destructive and do not consider variation in wood density (ρ). In this study, temporal variation in C content of Pinus cooperi Blanco was determined at a site in the Sierra Madre Occidental, Durango, Mexico. Chronologies of carbon capture in this species were obtained using dendrochro-nology to date growth rings and allometric relationships to estimate biomass, including ρ. Our results indicate that temporal variation in C is related to temporal variation in ρ. Such variation likely depends on environmental and spatial conditions at site. Comparison of our results with those obtained without taking into account ρ shows that neglecting ρ under-estimates C capture by more than 50%, representing a variation of up to 266.51 mg at this site. Our more accurate C estimates are relevant to establishing effects of climate change on C flows in ecosystems. This is the first study to use such methodology to estimate C capture in Mexico, providing important information on C flows and forest productivity for this region. 2016 artículo científico 0188-6266 https://www.redalyc.org/articulo.oa?id=41649084002 https://www.redalyc.org/journal/416/41649084002/ https://www.redalyc.org/journal/416/41649084002/html/ https://www.redalyc.org/journal/416/41649084002/41649084002.epub https://www.redalyc.org/journal/416/41649084002/movil en http://www.redalyc.org/revista.oa?id=416 Acta Universitaria application/pdf Universidad de Guanajuato Acta Universitaria (México) Num.6 Vol.26
