Chlamydomonas reinhardtii Extinction Risk Under Environmental Change

Data from a study by Josianne Lachapelle compares extinction risk for Chlamydomonas reinhardtii algal populations with different selection histories. The experiment exposed spores and lines from benign, single-stress, and double-stress histories to severe environmental changes. Findings show higher extinction risk for populations with a history of selection in stressful environments.

Use Cases

• Analyze extinction risk across populations with histories of selection in benign versus stressful environments.
• Investigate the historical contingency of extinction rates using repeatability data within selection histories.
• Model the effect of selection history on population survival during severe environmental change.

Strengths

• Data originates from a controlled experiment on Chlamydomonas reinhardtii, published in 2020.
• Study design includes comparisons across three distinct population selection histories (benign, one-stress, two-stress).
• Findings demonstrate strong repeatability of extinction rates within each selection history.

Limitations

• Dataset size, row count, and specific variables are not detailed in the provided metadata.
• Scope is limited to a single model organism (Chlamydomonas reinhardtii) in a laboratory setting.
• Data is static from a 2020 study and does not represent ongoing updates.
