Sexual Selection
5 claims checked
Some sexually selected traits reduce heat tolerance, survival, or performance under thermal stress.
Claim:
Thermal selection and sexual selection can act in opposite directions in shaping organismal phenotypes.
NOT BS
Thermal stress generally suppresses testosterone and impairs male reproductive physiology.
Claim:
In males living in the Kalahari environment, elevated circulating testosterone indicates that a sexual-selection-related physiological axis remains active in the population despite thermal stressors.
TOTAL BS
Testosterone often mediates male-typical sexually selected traits, but other hormones also drive dimorphism across taxa.
Claim:
Testosterone is the principal endocrine mechanism by which sexual selection translates into morphological sexual dimorphism.
SOME BS
Sexually selected traits often impose physiological costs that intensify under environmental stress.
Claim:
Physiological costs of expressing sexually selected traits (for example, elevated thermal loads) can oppose natural selection that would otherwise favor smaller or less ornamented phenotypes, especially under environmental stress.
