Brachionus Rotifer Life History and Transcriptomic Responses to Temperature

Comparative life-table experiments and transcriptomic analyses of heat-tolerant and heat-sensitive Brachionus rotifer species reveal opposing survival and growth strategies. The work, led by Sofia Paraskevopoulou from the University of Potsdam, identifies heat shock protein expression as a key component of thermal adaptation. It demonstrates sweeping reorganizations of biological functions, including energy and lipid metabolism, in response to elevated temperatures.

Use Cases

• Modeling population dynamics under thermal stress based on cross-temperature life-table experiments.
• Identifying genetic markers for heat tolerance based on comparative transcriptomic analyses of heat shock proteins.
• Studying metabolic pathway regulation in response to climate change based on expression patterns in energy and lipid metabolism genes.
• Investigating epigenetic responses to environmental stress based on gene expression related to histone modifications in the heat-sensitive species.

Strengths

• Data compares two closely related species that occur in sympatry, allowing for direct evolutionary comparisons.
• Analysis integrates organism-level life history traits with molecular-level gene expression data.
• Findings reveal both shared and opposing transcriptomic responses to heat between species.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
