Resumen
Este resumen es generado por máquina.Miles de sitios arqueológicos precolombinos no descubiertos, incluidos 24 nuevos trabajos de tierra, se han revelado en el Amazonas utilizando detección y alcance de luz (LIDAR). Estos hallazgos sugieren una significativa modificación humana antigua de los bosques amazónicos y los árboles domesticados asociados.
Área De La Ciencia
- Arqueología
- Ciencias del medio ambiente
- Detección remota
Sus Antecedentes
- Las sociedades indígenas amazónicas tienen una larga historia, con evidencia de ocupación durante más de 12.000 años.
- El alcance del antiguo impacto humano en los ecosistemas forestales amazónicos sigue siendo en gran medida desconocido.
Objetivo Del Estudio
- Descubrir sitios arqueológicos precolombinos no descubiertos en la cuenca del Amazonas.
- Estimar el número de sitios arqueológicos no descubiertos y su distribución.
- Identificar pruebas potenciales de prácticas pasadas de manejo forestal por parte de sociedades antiguas.
Principales Métodos
- Utilizó datos de detección y alcance de luz (LIDAR) para identificar características arqueológicas debajo del dosel del bosque.
- Modelado espacial empleado para estimar la distribución y abundancia de sitios arqueológicos a gran escala.
- Analizó la asociación entre las ocurrencias de los trabajos de tierra y las especies de árboles domesticados.
Principales Resultados
- Descubrieron 24 trabajos de tierra precolombinos no detectados anteriormente a través de la cuenca del Amazonas.
- Las estimaciones modeladas sugieren entre 10.272 y 23.648 sitios arqueológicos no descubiertos, predominantemente en el suroeste.
- Se identificaron 53 especies de árboles domesticados significativamente correlacionados con las ubicaciones de los trabajos de tierra, lo que indica un manejo anterior.
Conclusiones
- Los bosques cerrados del Amazonas albergan miles de sitios arqueológicos no descubiertos.
- Las sociedades precolombinas modificaron activamente estos bosques, influyendo en su estado actual.
- Este descubrimiento mejora la comprensión de la escala de la antigua influencia humana en la Amazonia.

Changes in the environment of the early Earth drove the evolution of organisms. As prokaryotic organisms in the oceans began to photosynthesize, they produced oxygen. Eventually, oxygen saturated the oceans and entered the air, resulting in an increase in atmospheric oxygen concentration, known as the oxygen revolution approximately 2.3 billion years ago. Therefore, organisms that could use oxygen for cellular respiration had an advantage. More than 1.5 years ago, eukaryotic cells and...
Around 4 billion years ago, oceans began to condense on earth while volcanic eruptions released nitrogen, carbon dioxide, methane, ammonia, and hydrogen into the primordial atmosphere. However, organisms with the characteristics of life were not initially present on earth. Scientists have used experimentation to determine how organisms evolved that could grow, reproduce, and maintain an internal environment.
In the 1920s, the scientists Oparin and Haldane proposed the idea that simple...
Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.
Perforation and dissection often occur during the initial stages of...
In brick wall construction, supporting structures are crucial for openings like windows and doors to maintain the integrity and support the weight of the wall above. These supports include lintels, corbels, and arches, each serving specific structural purposes.
Lintels are primary supports used to span openings and can be crafted from materials such as reinforced concrete, steel-reinforced brick masonry, or simple steel angles. These are straightforward to install and are typically concealed...
Ecological succession is influenced by the processes of facilitation, inhibition, and toleration. Facilitation occurs when early successional species create more favorable ecological conditions for subsequent species, such as enhanced nutrient, water, or light availability. In contrast, inhibition happens when early successional species create unfavorable ecological conditions for potential successive species, such as limiting resource availability. In some cases, later successional species...
Plants obtain inorganic minerals and water from the soil, which acts as a natural medium for land plants. The composition and quality of soil depend not only on the chemical constituents but also on the presence of living organisms. In general, soils contain three major components:
Inorganic mineral matter, which constitutes about 40 to 45 percent of the soil volume.
Organic matter, also known as humus, which makes up about 5 percent of the soil volume.
Water and air, covering about 50...
