Novel organisms: comparing invasive species, GMOs, and emerging pathogens

Area of Science:

• Ecology
• Environmental Science
• Risk Assessment

Background:

• Novel organisms, including invasive species, genetically modified organisms (GMOs), and emerging pathogens, increasingly impact the global environment.
• Effective management and policy decisions regarding these novel organisms are hindered by fragmented research and terminology.

Purpose of the Study:

• To propose a comparative framework for understanding the life stages of novel organisms.
• To establish common terminology for novel organisms to improve interdisciplinary knowledge exchange.
• To explore the influence of climate change and biodiversity on the establishment, spread, and impact of novel organisms.

Main Methods:

• Development of a conceptual framework for classifying and comparing novel organisms.
• Analysis of stage transitions and their causes/consequences.
• Integration of climate change and biodiversity interactions within the framework.

Main Results:

• The proposed framework provides a standardized approach for comparing diverse novel organisms.
• It facilitates the transfer of knowledge from well-studied groups (e.g., invasive species) to less-studied ones (e.g., GMOs, pathogens).
• The framework highlights climate change and biodiversity as key drivers influencing novel organism dynamics.

Conclusions:

• The framework enhances understanding of novel organism ecology and risk.
• It promotes better communication and decision-making among scientists, managers, and policymakers.
• It underscores the interconnectedness of novel organisms, climate change, and biodiversity.
