Resumen

Los efectos heredados de la destrucción del hábitat, como la deuda de extinción, pueden desestabilizar los sistemas socioecológicos. Estas deudas de servicios ecosistémicos dependientes de la biodiversidad reducen los espacios de operación seguros y pueden causar un colapso inesperado del sistema.

Área de la Ciencia:

Ciencias del Sistema Terrestre
Ecología
Sistemas sociales y ecológicos

Sus antecedentes:

El Antropoceno se caracteriza por un rápido cambio ambiental, lo que lleva a efectos de legado.
La deuda de extinción de especies, resultante de la destrucción del hábitat en el pasado, es un efecto heredado significativo.
La pérdida de biodiversidad puede conducir a deudas de servicios ecosistémicos, lo que afecta a las sociedades humanas.

Objetivo del estudio:

Investigar el impacto de las deudas de servicios ecosistémicos dependientes de la biodiversidad en las trayectorias de los sistemas socioecológicos.
Analizar cómo estas deudas afectan la estabilidad del sistema y los espacios operativos seguros.

Principales métodos:

Un estudio teórico utilizando un modelo de sistemas dinámicos.
El modelo incorpora deudas de servicios ecosistémicos dependientes de la biodiversidad que surgen de la destrucción del hábitat.

Principales resultados:

Las deudas de servicios ecosistémicos dependientes de la biodiversidad reducen los espacios de operación seguros y crean puntos de inflexión ambientales.
Las transiciones del sistema pueden exhibir transientes largos de estabilidad aparente, enmascarando la inestabilidad subyacente.
Estas deudas pueden aparecer inicialmente como recuperación, pero pueden preceder al colapso del sistema.

Conclusiones:

Las deudas por servicios ecosistémicos dependientes de la biodiversidad representan una amenaza significativa para la sostenibilidad del sistema socioecológico.
La gestión sostenible requiere una consideración explícita de estas deudas.
La estabilidad aparente del sistema en observaciones recientes puede no indicar de manera confiable el espacio de operación seguro de un sistema.

Ecological Disturbance

Ecological Disturbance

An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.

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...

Ecological Niches

Ecological Niches

All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.

Design Example: Analyzing Capacity Contours for Flood Risk Assessment

Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley. The engineers...

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.

Keystone Species

Keystone Species

Measures of species biodiversity, such as richness (i.e., the number of species present) and evenness (i.e., their relative abundance), describe an ecological community’s structure. Many factors affect community structure, including abiotic factors (e.g., sunlight and nutrients), disturbances (e.g., fire or flood), species interactions (e.g., predation or competition), and chance events (e.g., foreign species invasion). Certain species—such as keystone species—also play a...
