The carbon sink capacity of tropical forests is substantially affected by tree mortality. However, the main drivers of tropical tree death remain largely unknown. Here we present a pan-Amazonian assessment of how and why trees die, analysing over 120,000 trees representing > 3800 species from 189 long-term RAINFOR forest plots. While tree mortality...

La constante demanda de área para la producción y uso de Servicios Ecosistémicos, como consecuencia de la creciente población y consumo de recursos, conlleva a la pérdida de bosques y el declive de la biodiversidad. Con el objetivo de determinar el posible futuro de los bosques y la biodiversidad en el departamento de Antioquia (Colombia). En este...

A spatially explicit global map of tree symbioses with nitrogen-fixing bacteria and mycorrhizal fungi reveals that climate variables are the primary drivers of the distribution of different types of symbiosis.

Climate, species composition, and soils are thought to control carbon cycling and forest structure in Amazonian forests. Here, we add a demographics scheme (tree recruitment, growth, and mortality) to a recently developed non-demographic model—the Trait-based Forest Simulator (TFS)—to explore the roles of climate and plant traits in controlling for...
Article
Full-text available
Most of the planet's diversity is concentrated in the tropics, which includes many regions undergoing rapid climate change. Yet, while climate-induced biodiversity changes are widely documented elsewhere, few studies have addressed this issue for lowland tropical ecosystems. Here we investigate whether the floristic and functional composition of in...

COL-TREE es una red de investigadores colombianos interesados en estudiar la ecología a largo plazo del bosque tropical en contexto del cambio climático. Desde hace 15 años trabajamos estableciendo parcelas permanentes de vegetación siguiendo métodos estandarizados a nivel mundial y colaboramos con esfuerzos globales de monitoreo del bosque. Actual...

El municipio de Envigado se encuentra ubicado en el Valle de Aburrá; una región de gran diversidad por su composición fisiográfica y por sus condiciones climáticas, que abarca lugares desde los 1500 hasta los 2900 metros de altitud. El 35% de Envigado aún tiene cobertura boscosa con diferentes grados de conservación, esto equivale a alrededor de 2....
Article
Within the tropics, the species richness of tree communities is strongly and positively associated with precipitation. Previous research has suggested that this macroecological pattern is driven by the negative effect of water‐stress on the physiological processes of most tree species. This implies that the range limits of taxa are defined by their...

The study of floral phenology patterns and floral visitors of palms is key to understanding evolutionary interactions between plants and insects. We studied the flowering pattern and floral visitors of Wettinia kalbreyeri in an Andean montane forest of Colombia. We monitored 100 adult palms throughout 1-year and observed an asynchronous flowering p...

Tropical forests are global centres of biodiversity and carbon storage. Many tropical countries aspire to protect forest to fulfil biodiversity and climate mitigation policy targets, but the conservation strategies needed to achieve these two functions depend critically on the tropical forest tree diversity-carbon storage relationship. Assessing th...

A pesar de que hasta hace una década los bosques protectores del embalse La Fe estaban catalogados como áreas de conservación, los consiguientes procesos de urbanización, deforestación y minería que han tenido lugar en las zonas aledañas han llegado a poner en riesgo la provisión de agua para Medellín.

Full-text available
To understand the driving factors behind the specificity amongst plant visitors and potential pollinators, we identified Mystrops spp. from eight palm species representative of each of the major clades of Wettinia (Arecaceae). We collected 31 palm inflorescences of at least three individuals per species from three different regions of across the di...

Tropical forests are global centres of both biodiversity and carbon storage. Many tropical countries aspire to protect forest to fulfil biodiversity and climate mitigation policy targets, but the conservation strategies needed to achieve these two functions depend critically on the tropical forest diversity-carbon relationship and this remains larg...

Agradecimientos: Este trabajo es parte del proyecto " Dinámica del bosques Tropical " , cofinanciado por Colciencias-JBMED (contrato 393 de 2012). Conservation planning is a fundamental tool to define protected areas. We included Alfa and beta biodiversity parameters in a systematic way, using palms as a model group for conservation planning in the...

While Amazonian forests are extraordinarily diverse, the abundance of trees is skewed strongly towards relatively few ‘hyperdominant’ species. In addition to their diversity, Amazonian trees are a key component of the global carbon cycle, assimilating and storing more carbon than any other ecosystem on Earth. Here we ask, using a unique data set of...

Atmospheric carbon dioxide records indicate that the land surface has acted as a strong global carbon sink over recent decades1, 2, with a substantial fraction of this sink probably located in the tropics3, particularly in the Amazon4. Nevertheless, it is unclear how the terrestrial carbon sink will evolve as climate and atmospheric composition con...

La caracterización de las comunidades vegetales y la estructura de los bosques es necesaria para establecer los planes de restauración de un sitio. Sin embargo la acelerada transformación del paisaje no permite conocer adecuadamente estas características para muchos sitios. En el presente estudio utilizamos modelos de composición florística y estru...

Aim: The accurate mapping of forest carbon stocks is essential for understanding the global carbon cycle, for assessing emissions from deforestation, and for rational land-use planning. Remote sensing (RS) is currently the key tool for this purpose, but RS does not estimate vegetation biomass directly, and thus may miss significant spatial variati...

The study of plant dispersal systems improves our understanding of forest regeneration, the dynamics of plant populations and the ecological relationships that emerge within ecosystems. In this study we analyzed the patterns of seed dispersal systems for Colombia, in relation to the Amazonian, Andean, Caribbean, Upper Magdalena, Middle Magdalena, O...

Dry forests represent almost half of the world’s tropical forests and they are the most threatened ecosystems by human activities. The growing a knowledge in preservation of the few remaining underlines the significance of establishing monitoring strategies for dry forests which would illustrate their role in the context of the tropical forests’ pr...

Evidencias recientes indican que la biomasa del árbol más grande puede explicar significativamente la variación en la biomasa del bosque a lo largo de gradientes climáticos. Este resultado es importante ya que de poder extrapolarse a diferentes bosques tropicales permitiría hacer mediciones de carbono en campo de una forma rápida y económica. En es...
