Integrated genomics approaches in evolutionary and ecological endocrinology

Area of Science:

• Evolutionary biology
• Endocrinology
• Genomics

Background:

• Hormones regulate multiple phenotypic traits via target tissues, leading to genetic correlations.
• Hormone signaling pathways mediate phenotypic plasticity and polyphenism in response to environmental factors.
• Variation in hormone pathways can contribute to genotype-by-environment interactions across populations and species.

Purpose of the Study:

• To review how genomic approaches can elucidate the evolutionary causes and ecological implications of hormone signal variation.
• To explore how environmental cues are translated into phenotypic development through hormone pathways.
• To understand how hormone pathway divergence contributes to phenotypic diversification and speciation.

Main Methods:

• Utilizing genomic technologies to study naturally occurring variation in hormone signals.
• Examining components of hormone signaling pathways across individuals, populations, and species.
• Reviewing analytical and experimental technologies in genomics and hormone measurement.

Main Results:

• Genomic approaches offer insights into how environmental cues shape phenotypes via hormone pathways.
• Understanding genetic correlations and decoupling of hormone-mediated traits is crucial for adaptive evolution.
• Divergence in hormone pathways plays a significant role in phenotypic diversification and speciation.

Conclusions:

• Genomic studies are essential for understanding the evolutionary endocrinology of hormone signal variation.
• Hormone signal variation is a key factor in adaptive evolution and the generation of biodiversity.
• Emerging technologies promise new insights into the role of hormones in evolution and diversification.
