Towards a Comparative Framework of Demographic Resilience

Area of Science:

• Ecology
• Biodiversity Science
• Conservation Biology

Background:

• The global biodiversity crisis necessitates tools to understand species' responses to environmental changes.
• Existing resilience frameworks often focus on higher biological levels (ecosystems, communities), complicating species-level quantification.
• A lack of quantifiable demographic resilience metrics hinders cross-species comparisons.

Purpose of the Study:

• To introduce a novel framework for demographic resilience.
• To develop a set of quantifiable metrics for species resilience.
• To enable comparison of resilience across different species.

Main Methods:

• Synthesizing concepts from community and population ecology.
• Developing a theoretical framework for demographic resilience.
• Defining a suite of comparable metrics for empirical application.

Main Results:

• A new framework for demographic resilience has been established.
• A set of novel, cross-species comparable metrics for demographic resilience has been proposed.
• The framework bridges ecological theory with empirical measurement.

Conclusions:

• The proposed demographic resilience framework provides a quantifiable approach to assess species' vulnerability and persistence.
• This work offers a common currency for comparing resilience across diverse species, aiding conservation efforts.
• The metrics facilitate a deeper understanding of how populations respond to global change pressures.
