Organisms and responses to environmental change.

Area of Science:

• Ecology
• Environmental Science
• Conservation Biology

Background:

• Growing concern exists regarding environmental change and its impact on biodiversity.
• Current research often overlooks the diversity of potential organismal responses to environmental shifts.
• This diversity is critical for guiding research focus and conservation strategies.

Purpose of the Study:

• To highlight the need for broad-scale approaches, from genes to ecosystems, to understand organismal responses.
• To emphasize the importance of identifying rare, key, or unique genomes and physiologies for conservation.
• To introduce a framework for estimating survival probability in the face of environmental change.

Main Methods:

• Reviewing organismal responses across scales, from molecular to ecosystem levels.
• Integrating the concept of conservation physiology with wider ecological approaches.
• Developing a predictive equation for survival probability based on multiple interacting factors.

Main Results:

• Organismal responses to environmental change occur across diverse scales and require integrated study.
• The rate of environmental change dictates the critical biological processes for survival.
• A novel equation is formulated to estimate the probability of survival (Ps) considering physiological flexibility, gene pool modification, population size, fitness, dispersal, resource availability, environmental change rate, competition, predation, and habitat separation.

Conclusions:

• A comprehensive understanding of the diversity of organismal responses is essential for effective biodiversity conservation.
• Future conservation efforts must consider a wide range of biological scales and processes.
• The proposed framework offers a method to predict species' resilience to future environmental changes.
