Abstract The occurrence of annual growth rings in tropical trees—the result the seasonal activity vascular cambium—has been explained by water deficit or flooding periods. However, little is known about drivers tree‐ring formation under hyper‐humid conditions without clear dry periods (ever‐wet conditions). Shelford's law states that excess environmental resources limits plant growth. Accordingly, we hypothesize soil moisture, a slight reduction precipitation and light availability determine...
Abstract Tree‐ring science, or dendrochronology, is broadly applied in temperate regions not only to determine a tree's age but also as proxy for reconstructing the climatic and ecological conditions during tree growing season. Dendrochronology application lower latitudes (i.e., tropical regions) an emerging field due common belief that trees do exhibit rhythmic growth lack of thermal seasonality. However, body evidence demonstrates growth, driven mainly by water availability. The article...
Studying tree growth processes helps us evaluate the success of restoration efforts in recovering ecosystem such as carbon accumulation. Here, we study aboveground biomass dynamics four common‐endemic species from tropical Andes ( Quercus humboldtii , Retrophyllum rospigliosii Citharexylum subflavescens and Croton magdalenensis ), established main water supply basins Medellín, Colombia. We use measurements 19 permanent plots five censuses between 2010 2023 to develop equations a function t...
The Cativo (Prioria copaifera) forms very homogeneous forests called cativales in the flooded plains of some rivers from Costa Rica to Colombia. For over 70 years has been main base timber industry Colombian Darien area. Because high productivity and high-dominance trees, they represent one most prone tropical for sustainable forest management. objective this research is model diameter volume growth rates (absolute, mean relative) as a function age, using tree ring data derived...
Se presenta un análisis de retorno la inversión por implementación proyectos conservación parte Corporación VivoCuenca, Fondo Agua que opera en cuenca del río Chinchiná, Colombia, cual abastece ciudad Manizales. Este consiste el planteamiento catálogo escenarios Soluciones Basadas Naturaleza (SbN) propenden mejorar los servicios ecosistémicos retención sedimentos, secuestro carbono y regulación hídrica. Para cada conjunto SbN propuestos se evalúa su viabilidad financiera mediante inversión,...
Trees growing in floodplains develop mechanisms by which to overcome anoxic conditions. Prioria copaifera Griseb. grows on the of Atrato River, Colombia, and monodominant communities this species remain flooded for at least 6 months a year. The aims study were as follows: (i) compare variations tree-ring structure with varying river water levels; (ii) reconstruct levels from chronology porosity tree rings. Discs taken 12 trees, number vessels along 3-mm-wide radial transects was counted....

Introducción: Poco se conoce del potencial dendrocronológico de las Podocarpáceas en el trópico. Objetivo: Explorar tres especies podocarpáceas: Retrophyllum rospigliosii, Podocarpus oleifolius y Prumnopitys harmsiana. Métodos: Se muestrearon analizaron 88 árboles: 30 R. rospigliosii secciones transversales, 28 P. harmsiana, respectivamente, provenientes núcleos madera extraídos con barreno incrementos. Las muestras procesaron siguiendo técnicas dendrocronológicas estándar. Resultados: En...
Antecedentes y Objetivos: Algunas especies de Magnolia presentan una distribución muy restringida, situación que las hace altamente vulnerables a la extinción, teniendo en cuenta degradación actual causada por actividades humanas. Poco se conoce sobre el efecto variables ambientales uso del suelo sus poblaciones naturales. Por lo que, este estudio analiza dos peligro jardinensis M. yarumalensis, su relación con cobertura suelo. Métodos: Se realizaron recorridos campo los Andes...
ABSTRACT In 2015 a dispute arose between an electricity company (EC) and smallholder of teak plantation when the EC felled 80 trees (without consent owner) in linear transect under rural power-line-corridor (PLC), fragmenting stand two portions. The stated that there were no planted area PLC was established 2008. owner asserted he 2006 so 2008 should have seen trees. We used bomb radiocarbon ( 14 C) signal three dendrochronological dating five trees, by us 2016, to do this study determine...
