Responses to Drought and Flooding02:41

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.
Threats to Biodiversity01:50

Threats to Biodiversity

There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
Adaptations that Reduce Water Loss01:57

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
Global Climate Change01:50

Global Climate Change

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
Burn Injuries01:22

Burn Injuries

Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...
Ecological Disturbance02:26

Ecological Disturbance

An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.Ecological disturbances can be caused by an event as small as the trampling of underbrush to an incident as wide-ranging as a forest...

    Resumen

    El carbón vegetal en los suelos amazónicos indica frecuentes incendios forestales desde la época del Holoceno medio. Estos incendios, probablemente causados por cambios climáticos o actividad humana, fueron más frecuentes en tipos específicos de suelos.

    Área de la Ciencia:

    • * La ecología amazónica.
    • * Estudios paleoecológicos y medioambientales.
    • * Ciencias del suelo.

    Sus antecedentes:

    • * Las maduras selvas tropicales en el centro norte de la cuenca del Amazonas contienen depósitos de carbón vegetal.
    • * La presencia de carbón vegetal sugiere una historia de importantes eventos de incendios en la región.
    • * La distribución del carbón vegetal varía según los diferentes tipos de bosques y suelos.

    Objetivo del estudio:

    • * Investigar la ocurrencia y el momento de los incendios pasados de la selva tropical en la cuenca del Amazonas.
    • * Para determinar la relación entre la distribución del carbón vegetal y los tipos de suelo.
    • * Explorar las posibles causas de estos incendios históricos.

    Principales métodos:

    • * Muestreo de suelo en bosques maduros cerca de San Carlos de Río Negro.

  • * Datación por carbono 14 de carbón hallado en muestras de suelo.
  • * Análisis de la distribución del carbón vegetal en los suelos Oxisols, Ultisols, caatinga e igapo.
  • Principales resultados:

    • * El carbón vegetal está muy extendido en los bosques de tierra firme Oxisols y Ultisols.
    • * La datación por carbono-14 revela numerosos incendios ocurridos desde la época media del Holoceno.
    • * El carbón vegetal es menos frecuente en los suelos forestales de caatinga e igapo.

    Conclusiones:

    • * La cuenca del Amazonas ha experimentado incendios forestales recurrentes a lo largo del Holoceno medio y más allá.
    • * La frecuencia y distribución del fuego están influenciadas por el tipo de suelo.
    • * Tanto los cambios climáticos como las actividades humanas son factores plausibles de estos incendios históricos de la selva tropical.
