Resumen

La diversidad biológica (biodiversidad) abarca toda la vida, desde los genes hasta los ecosistemas. Si bien es difícil de medir, el estudio de sus facetas revela pérdidas alarmantes impulsadas por el hombre que afectan las funciones del ecosistema.

Área de la Ciencia:

Ecología Ecología Ecología.
Biología evolutiva Biología evolutiva.
Ciencias de la Conservación Ciencias de la Conservación.

Sus antecedentes:

La diversidad biológica (biodiversidad) se define como la suma de todas las variaciones bióticas entre genes, especies y ecosistemas.
La medición del alcance completo de la biodiversidad presenta desafíos significativos.
Comprender los impulsores y las consecuencias de la pérdida de biodiversidad es fundamental.

Objetivo del estudio:

Explorar métodos para medir la biodiversidad.
Investigar los factores ecológicos y evolutivos que dan forma a la biodiversidad.
Evaluar el impacto de las actividades humanas en la biodiversidad y el funcionamiento del ecosistema.

Principales métodos:

Análisis filogenéticos para comprender las relaciones evolutivas.
Análisis temporales para estudiar los cambios en la biodiversidad a través del tiempo.
Examen de las facetas de la biodiversidad para revelar patrones y tendencias.

Principales resultados:

La biodiversidad, aunque no se puede reducir a una sola métrica, puede estudiarse a través de facetas específicas que producen descubrimientos significativos.
Los análisis filogenéticos y temporales iluminan los procesos que dan forma a la biodiversidad.
Las actividades humanas están causando tasas rápidas y alarmantes de pérdida de biodiversidad.

Conclusiones:

A pesar de los desafíos en la medición, el estudio de las facetas de la biodiversidad ofrece ideas cruciales.
La pérdida de biodiversidad inducida por el hombre representa una amenaza significativa para el funcionamiento del ecosistema.
Los esfuerzos de investigación actuales, aunque valiosos, son insuficientes dada la escala de la diversidad desconocida y la urgencia de las necesidades de conservación.

What is Biodiversity?

What 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.

Threats to Biodiversity

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...

Biodiversity and Human Values

Biodiversity 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.

Habitat Fragmentation

Habitat 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.

Methods to Assess Microbial Communities

Methods to Assess Microbial Communities

Microbial communities, comprising bacteria, archaea, and eukaryotic microorganisms, inhabit diverse ecosystems and play crucial roles in environmental and biological processes. Their diversity is defined by three main parameters: species richness (the number of distinct species), species abundance (the relative quantity of each species), and species evenness (how uniformly individual species are distributed in various locations). These factors together shape the structure and ecological balance...
