Temperature as a Driver of Phage Ecology and Evolution

Area of Science:

• Microbiology
• Ecology
• Evolutionary Biology

Background:

• Bacteriophages (phages) are ubiquitous microorganisms crucial for bacterial ecology and evolution.
• Phages inhabit diverse thermal environments but are sensitive to temperature fluctuations.
• Global climate change is increasing the frequency and intensity of thermal perturbations.

Purpose of the Study:

• To assess the impact of the thermal environment on phage biology globally.
• To identify key thermal niches for phages.
• To explore temperature's role in phage life-history, interactions, and evolution.

Main Methods:

• Review of theoretical and empirical evidence.
• Analysis of phage distribution across thermal gradients.
• Synthesis of data on phage responses to temperature.

Main Results:

• Temperature significantly influences phage life-history strategies and ecological interactions.
• Thermal variation affects phage evolutionary dynamics and functions in microbial communities.
• Phage sensitivity to temperature has implications for their use as biomedical therapeutics.

Conclusions:

• The thermal environment is a critical factor shaping phage biology and ecological impact.
• Understanding phage thermal sensitivity is vital for predicting their response to climate change.
• Phage thermal properties are important considerations for therapeutic applications.
