Climate change is reshaping ecosystems at an unprecedented pace, and understanding the biological mechanisms that underpin adaptation has never been more important. Amino acids—fundamental to protein structure, metabolism, and stress physiology—play central roles in how organisms respond to shifting environmental conditions. As part of our commitment to advancing high-impact research, Amino Acids, an international fully Open Access journal with an Impact Factor of 2.4, is pleased to announce a new Collection exploring the multifaceted relationships between amino acids and climate‑induced environmental challenges.

The Special Issue “Amino Acids and Climate Changes: Molecular, Physiological, and Ecological Perspectives” focuses on the critical roles amino acids play in supporting resilience and adaptation across ecosystems. Climate change drives alterations in temperature patterns, water availability, soil chemistry, and atmospheric composition, placing remarkable stress on plants, microbes, and certain animal species. Amino acids serve as key molecular mediators in these responses—supporting metabolic flexibility, cellular protection, and physiological adjustments necessary for survival.

Emerging research highlights how amino acid metabolism contributes not only to organismal resilience but also to ecosystem functioning. Amino acids influence nutrient cycling, soil and water chemistry, and biogeochemical processes essential for maintaining ecosystem stability under changing climatic conditions. In the context of global food security, such insights are particularly timely. Understanding amino acid–driven adaptation pathways enables the development of strategies for strengthening resilience in crops, aquaculture, and terrestrial and marine environments.

Looking ahead, breakthroughs in this area may reveal new amino acid structures, metabolic pathways, and molecular mechanisms that confer enhanced stress tolerance. These discoveries could enable innovative approaches in bioengineering—supporting climate‑resilient crops, microorganisms, and small animal models capable of thriving in increasingly variable environments. As the pressures of climate change intensify, such advances will be vital to protecting food systems and preserving ecological integrity.

This Collection aligns with and supports global sustainability priorities, including SDG 13 (Climate Action) and SDG 14 (Life Below Water).

We welcome submissions of original research articles, mini reviews, and full reviews that broaden our understanding of the roles of amino acids, peptides, and proteins in climate change biology.

Important Notes for Authors

1. Article Processing Charges (APCs):
   APCs may be fully covered under institutional agreements that Springer Nature has with numerous organizations worldwide. Authors are encouraged to verify coverage through their institution or the journal’s website. If your institution is not listed, please contact both the journal and the Collection Editor for support.

2. Rolling Publication:
   Articles will be added to the Collection upon acceptance; authors do not need to wait for the full Collection to close before publication.
