Area of Science:

• Environmental Science
• Molecular Biology
• Genetics

Background:

• Organismal phenotypes are influenced by thermal environments.
• Global temperature unpredictability necessitates understanding molecular responses to thermal variation.
• Variation in temperature-dependent processes is key to climate change adaptation.

Purpose of the Study:

• To explore mechanistic processes underlying temperature-sensitive phenotypes.
• To synthesize literature on variable thermal conditions' effects on these processes.
• To propose a framework for future research on organismal responses to transient thermal environments.

Main Methods:

• Utilizing temperature-dependent sex determination as a model system.
• Synthesizing current literature on thermal responses.
• Developing a framework to address mechanistic and ecological questions.

Main Results:

• Identified key questions regarding direct/indirect gene responses to temperature.
• Highlighted the importance of response timing for proteins and genes.
• Emphasized the need for ecologically relevant experimental temperature manipulations.

Conclusions:

• A framework is proposed to systematically investigate organismal responses to transient thermal environments.
• Understanding molecular mechanisms of thermal adaptation is vital for predicting climate change impacts.
• Integrating mechanistic and ecological approaches will advance the study of climate change resilience.
