Resumen

A nivel mundial, una quinta parte de las especies de vertebrados están amenazadas, y las tasas de extinción aumentan anualmente. Los esfuerzos de conservación mitigan las pérdidas adicionales, pero son insuficientes para combatir los factores primarios como la pérdida de hábitat y la sobreexplotación.

Área de la Ciencia:

Biología de la Conservación Biología de la Conservación.
Zoología Zoología Zoología.
Ecología Ecología Ecología.

Sus antecedentes:

La Lista Roja de la Unión Internacional para la Conservación de la Naturaleza (UICN) clasifica el riesgo de extinción de las especies.
Las poblaciones de vertebrados enfrentan amenazas crecientes a nivel mundial.
Comprender el estado de las especies es crucial para las estrategias efectivas de conservación.

Objetivo del estudio:

Para evaluar el estado actual de conservación de los vertebrados del mundo.
Para cuantificar la tasa de declive de las especies hacia la extinción.
Evaluar el impacto de las acciones de conservación e identificar las amenazas persistentes.

Principales métodos:

Análisis de datos de 25.780 especies de vertebrados de la Lista Roja de la UICN.
Cálculo de los cambios anuales en las categorías de riesgo de extinción de mamíferos, aves y anfibios.
Evaluación de los éxitos de conservación e identificación de los principales factores de pérdida de biodiversidad.

Principales resultados:

Una quinta parte de las especies de vertebrados evaluadas se clasifican como amenazadas.
Un promedio de 52 especies de mamíferos, aves y anfibios se acercan cada año a la extinción.
Los éxitos en la conservación han evitado al menos una tasa de deterioro un 20% mayor.

Conclusiones:

Las iniciativas actuales de conservación son insuficientes para contrarrestar los principales impulsores de la pérdida de biodiversidad.
La expansión agrícola, la tala, la sobreexplotación y las especies invasoras siguen siendo amenazas críticas.
Se requieren esfuerzos de conservación urgentes y mejorados para proteger la biodiversidad de los vertebrados.

What is Conservation Biology?

What is Conservation Biology?

Conservation biology is a scientific field that focuses on the preservation of biodiversity in order to protect ecosystems while meeting the needs of the human population. Humans require properly functioning ecosystems to maintain our supply of natural resources, including food, medicines, and building materials.

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...

Conservation of Small Populations

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less likely to...

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.

Conservation of Declining Populations

Conservation of Declining Populations

Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.

Sustainable Development

Sustainable Development

As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.
