Resumen
Amazonia peruana en el Amazonas peruano.
Área de la Ciencia:
- Ecología Ecología Ecología.
- La biogeografía es la biogeografía.
- Biología de la Conservación Biología de la Conservación.
Sus antecedentes:
- Los estudios biogeográficos tradicionales en las selvas tropicales amazónicas se centran en barreras como el clima, las montañas y los ríos.
- La heterogeneidad ecológica dentro de los bosques no inundados (tierra firme) a menudo se pasa por alto, a pesar de las influencias conocidas de las diferencias del suelo (edáfico) en la distribución de las especies.
Objetivo del estudio:
- Para cuantificar la heterogeneidad del paisaje en la Amazonia de las tierras bajas peruanas.
- Evaluar el significado ecológico de la heterogeneidad actual dentro de los bosques de tierra firme.
Principales métodos:
- Estudios de campo en toda la Amazonia de las tierras bajas peruanas (500,000 km2).
- Análisis de imágenes satelitales para mapear las características del paisaje.
Principales resultados:
- La Amazonia peruana exhibe una heterogeneidad de paisajes significativamente mayor de lo que se entendía anteriormente.
- Las variaciones edaficas contribuyen a esta heterogeneidad dentro de la tierra firme.
Conclusiones:
- La comprensión actual de los patrones de biodiversidad amazónica puede ser incompleta.
- Las implicaciones para la investigación, la gestión y las estrategias de conservación de la biodiversidad en la región son sustanciales.

02:22Introduction to Plant Diversity
From Water to Land
01:19What is Biodiversity?
Biodiversity describes the variety of living things at multiple organizational levels: genetic, species and ecosystem diversity. Species diversity includes all branches of the evolutionary tree from single-celled prokaryotic organisms, bacteria, and archaea, to the eukaryotic kingdoms: plants; animals; fungi; and protists. To date, there have been about 1.75 million species identified, and new species are discovered every week.
02:31Habitat Fragmentation
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.
01:50Threats 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...
01:24Biodiversity and Human Values
Human civilization relies on biodiversity in many ways. Sudden changes in species biodiversity result in environmental changes that can modify weather patterns and therefore human civilizations.
02:54Evolutionary Relationships through Genome Comparisons
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...
