Claim · model-written summary
Heritable changes in growth traits are proposed to affect the whole stress resistance syndrome through physiological linkage.
- Outcome
- evolution of the entire SRSe0
- Qualifier
- physiological linkages between growth-related traits and the SRSe0

e0“Because of physiological linkages between growth-related traits and the SRS, any heritable change in a key growth-related trait will pleiotropically affect the SRS. Therefore, heritable changes in these key growth-related traits could be accompanied by evolution of the entire SRS.”
Title
Evolution of Suites of Traits in Response to Environmental Stress
F. Stuart Chapin; Kellar Autumn; Francisco Pugnaire The American Naturalist 1993. doi:10.1086/285524
Other claims from this paper (6)
- Association Low-resource exploitation traits are physiologically linked to low photosynthesis, nutrient uptake and growth.
- Observation Similar stress-associated suites arise as plastic and evolutionary responses.
- Observation Single-gene mutants, metal-tolerant populations and resource gradients support the proposed linked-trait evolution.
- Mechanism The authors propose that a genetic switch could broaden expression of stress resistance and make high-resource genotypes more tolerant.
- Mechanism Short-lived species may respond evolutionarily to rapid environmental change.
- Mechanism Generation time may prevent mature long-lived species from keeping pace with rapid global change.
