Resumen

La protección de los mamíferos terrestres requiere la conservación del 11% de la Tierra para salvaguardar el 10% de sus rangos. Este análisis global destaca la necesidad urgente de estrategias de conservación para prevenir los riesgos de extinción de los mamíferos terrestres.

Área de la Ciencia:

Biología de la conservación Biología de la conservación.
Zoología Zoología Zoología.
La investigación de la biodiversidad en la investigación de la biodiversidad.

Sus antecedentes:

Una parte significativa de las especies y poblaciones de mamíferos terrestres se enfrentan a riesgos de extinción.
Los factores que contribuyen al riesgo incluyen la rareza, los impactos humanos y las fronteras políticas.

Objetivo del estudio:

Para llevar a cabo un análisis de conservación global para los mamíferos terrestres.
Identificar las áreas prioritarias de conservación para preservar la biodiversidad de los mamíferos.

Principales métodos:

Utilizó una nueva base de datos global de mamíferos terrestres.
Se empleó un análisis de complementariedad para seleccionar áreas de conservación prioritarias.
Evaluó la superficie de tierra requerida para proteger los rangos geográficos de mamíferos.

Principales resultados:

Aproximadamente el 11% de la superficie terrestre de la Tierra necesita gestión para su conservación.
Esta área tiene como objetivo preservar al menos el 10% de los rangos geográficos de mamíferos terrestres.
Una fracción sustancial de las poblaciones de mamíferos están en riesgo.

Conclusiones:

Los esfuerzos mundiales de conservación deben centrarse en áreas terrestres específicas para proteger a los mamíferos.
Es necesaria una combinación de protección de la reserva y mejora del paisaje.
Se necesitan medidas urgentes para hacer frente a la crisis de extinción que enfrentan los mamíferos terrestres.

Parental Care

Parental Care

Many animals exhibit parental care behavior, including feeding, grooming, and protecting young offspring. Parental care is universal in mammals and birds, which often have young that are born relatively helpless. Several species of insects and fish, as well as some amphibians, also care for their young.

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...

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.

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.

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...

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.
