Biomasa de los bosques tropicales: una nueva estimación basada en los volúmenes forestales
Science (New York, N.Y.)
|March 23, 1984
Resumen
La biomasa de los bosques tropicales es menor de lo que se pensaba anteriormente, con una biomasa total de 205.000 millones de toneladas. Este hallazgo afecta nuestra comprensión del presupuesto de carbono terrestre y el papel de los bosques en el ciclo global del carbono.
Área de la Ciencia:
- Ecología Ecología Ecología.
- Silvicultura La silvicultura es la actividad forestal.
- Biogeoquímica La biogeoquímica es la bioquímica.
Sus antecedentes:
- La estimación precisa de la biomasa de los bosques tropicales es crucial para comprender el presupuesto global de carbono.
- Es posible que las estimaciones anteriores de la biomasa de los bosques tropicales hayan sido sobreestimadas.
Objetivo del estudio:
- Para recalcular las densidades de biomasa y la biomasa total de los bosques tropicales utilizando datos recientes.
- Para comparar las nuevas estimaciones con los informes anteriores y evaluar las implicaciones para el presupuesto global de carbono.
Principales métodos:
- Utilizó evaluaciones recientes de áreas de bosques tropicales y volúmenes de stock.
- Densidades de biomasa calculadas y biomasa total basadas en estas evaluaciones.
Principales resultados:
- Se estima que la biomasa total de los bosques tropicales es de 205 x 10^9 toneladas.
- Densidades de biomasa ponderadas determinadas para bosques cerrados no perturbados (176 toneladas/hectárea) y bosques de hoja ancha abiertos (61 toneladas/hectárea).
- Las nuevas estimaciones son significativamente más bajas que los valores reportados anteriormente.
Conclusiones:
- Las estimaciones revisadas de menor biomasa desafían los modelos existentes del presupuesto de carbono terrestre.
- El papel de los bosques tropicales en el secuestro global de carbono requiere una reevaluación.

00:46Trophic Efficiency
Trophic level transfer efficiency (TLTE) is a measure of the total energy transfer from one trophic level to the next. Due to extensive energy loss as metabolic heat, an average of only 10% of the original energy obtained is passed on to the next level. This pattern of energy loss severely limits the possible number of trophic levels in a food chain.
01:25Biofuels
The microbial conversion of organic matter into biofuels holds potential as a renewable energy source. Among biofuel sources, microalgae are recognized as a highly efficient and adaptable feedstock for biodiesel production, owing to their rapid biomass accumulation, elevated lipid productivity, and capacity to proliferate in diverse aquatic systems, including freshwater, marine, and wastewater habitats. Unlike terrestrial crops, microalgae do not compete for land and can achieve significantly...
01:28Softwoods and Hardwoods
Softwoods and hardwoods, derived from different types of trees, are distinguished by their leaf structures and cellular compositions, each serving unique purposes in construction and manufacturing. Softwoods come from cone-bearing trees with needle-like leaves and are predominantly composed of longitudinal cells called tracheids and a smaller proportion of radial cells known as rays. Due to their cellular structure, softwoods are commonly used in construction for structural frames, sheathing,...
01:05Estimation of the Physical Quantities
On many occasions, physicists, other scientists, and engineers need to make estimates of a particular quantity. These are sometimes referred to as guesstimates, order-of-magnitude approximations, back-of-the-envelope calculations, or Fermi calculations. The physicist Enrico Fermi was famous for his ability to estimate various kinds of data with surprising precision. Estimating does not mean guessing a number or a formula at random. Instead, estimation means using prior experience and sound...
01:27Growth Models with Integration: Problem Solving
In population modeling, integration provides a systematic way to determine accumulated quantities from known rates of change. One such application arises in ecology, where the total weight of a fish population in a body of water is referred to as its biomass. When the rate of growth of this biomass is known as a function of time, calculus can be used to determine the total biomass at a future date.Growth Rate and Biomass FunctionLet the growth rate of the fish population be represented by a...
01:06Primary Production
The total amount of energy acquired by primary producers in an ecosystem is called gross primary production (GPP). However, of this energy, producers use some for metabolic processes, and some is lost as heat, decreasing the amount of energy available to the next trophic level. The remaining usable amount of energy is called the net primary productivity (NPP). In terrestrial ecosystems, NPP is driven by climate, while light penetration and nutrient availability drive NPP in aquatic ecosystems.
