Laboratory simulations

Definition

Laboratory simulations are controlled experiments that mimic real-world processes, allowing researchers to study complex systems in a safe and manageable environment. These simulations provide insights into how organisms respond to varying conditions, such as changes in pH or temperature, which is crucial for understanding phenomena like ocean acidification and its impacts on calcifying organisms. By replicating specific environmental conditions, these simulations help to predict potential outcomes and inform conservation strategies.
