The dimensions of evolutionary potential in biological conservation

Area of Science:

• Ecology
• Evolutionary Biology
• Conservation Science

Background:

• Ecologists increasingly recognize the need to preserve evolutionary processes for biodiversity adaptation to environmental changes.
• The concept of 'conservation of evolutionary potential' is frequently cited in scientific literature.
• Conflicting conservation objectives (e.g., species richness vs. ecosystem services) and differing values of biodiversity (intrinsic vs. instrumental) complicate the definition of evolutionary potential.

Purpose of the Study:

• To critically examine the concept of conserving evolutionary potential in biodiversity conservation.
• To highlight the need for explicit normative frameworks underlying different conservation visions.
• To propose four key dimensions for positioning conservation of evolutionary potential strategies.

Main Methods:

• Conceptual analysis of the term 'conservation of evolutionary potential'.
• Identification of underlying normative commitments in biodiversity conservation.
• Development of a framework with four dimensions for evaluating conservation strategies.

Main Results:

• The concept of evolutionary potential and its conservation are problematic without explicit normative underpinnings.
• Different conservation goals and values lead to divergent interpretations and applications.
• A four-dimensional framework is proposed: vehicles of evolutionary potential, temporality, measurability, and human influence.

Conclusions:

• Advocates for conserving evolutionary potential must clarify their position on these four dimensions.
• Addressing these dimensions is crucial for determining the appropriateness and application of evolutionary potential as a conservation target.
• This framework aims to refine and guide biodiversity conservation efforts by integrating evolutionary considerations with explicit values and goals.
