Wood density is a critical control on tree biomass, so poor understanding of its spatial variation can lead to large and systematic errors in forest biomass estimates and carbon maps. The need to understand how and why wood density varies is especially critical in tropical America where forests have exceptional species diversity and spatial turnove...

Tree growth and longevity trade-offs fundamentally shape the terrestrial carbon balance. Yet, we lack a unified understanding of how such trade-offs vary across the world’s forests. By mapping life history traits for a wide range of species across the Americas, we reveal considerable variation in life expectancies from 10 centimeters in diameter (r...

Aim Water availability is the major driver of tropical forest structure and dynamics. Most research has focused on the impacts of climatic water availability, whereas remarkably little is known about the influence of water table depth and excess soil water on forest processes. Nevertheless, given that plants take up water from the soil, the impacts...

Tropical forests are the most diverse and productive ecosystems on Earth. While better understanding of these forests is critical for our collective future, until quite recently efforts to measure and monitor them have been largely disconnected. Networking is essential to discover the answers to questions that transcend borders and the horizons of...

Selective logging in the tropics is a major driver of forest degradation by altering forest structure and function, including significant losses of aboveground carbon. In this study, we used a 30-year Landsat time series (1985–2015) to analyze forest degradation and carbon emissions due to selective logging in a Forest Reserve of the Venezuelan Ama...

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...

The allometric relations of diameter and height were analyzed for 34 tree species of the Imataca Forest Reserve, according to the Chapman and Richard equation used in the individual-based ZELIG and FACET models that simulate forest dynamics. The two allometric coefficients employed were calculated by linear regression applied to the logarithmic tra...

Las relaciones alómetricas diámetro-altura fueron analizadas en 34 especies arbóreas de la Reserva Forestal Imataca, según la ecuación exponencial de Chapman y Richard, utilizada por los modelos de base individual ZELIG y FACET, que simulan la dinámica de crecimiento del bosque. Los coeficientes de la relación alométrica para cada especie fueron ca...

RESUMEN Se realizó un censo de los árboles mayores de 10 cm de dap en 550 hectáreas en el bosque El Caimital, Municipio Obispos del estado Barinas, y en 440 hectáreas del bosque El Manguito, Municipio Páez del estado Portuguesa, de las especies Swietenia macrophylla (caoba), Cedrela odorata (cedro), Anacardium excelsum (mijao), Symmeria paniculata...

Tree mortality and recruitment was studied in a Tropical lower montane moist forest (sensu Holdridge) located in the Venezuelan Andes (8º39'N; 71º24'O). Data from six 0,25 ha permanent plots, with 23 successive measurements (1968 - 2000) were used to analyze tree mortality in individuals with a breast height diameter (dbh) = 10 cm. Fifty five tree...
