Other claims from this paper (17)
- Intervention effect Under supplemental UV-B in the laboratory, Fv/Fm decreased in the aquatic bryophytes (among the most consistent responses).
- Intervention effect Under supplemental UV-B in the laboratory, DNA damage increased in the aquatic bryophytes (among the most consistent responses).
- Intervention effect Under supplemental UV-B in the laboratory, global UV absorbance and the concentrations of p-coumaroylmalic and p-coumaric acids increased in Jungermannia cordifolia.
- Intervention effect Under supplemental UV-B in the laboratory, kaempferol increased in Bryum pseudotriquetrum.
- Observation Responses of the aquatic bryophytes to UV-B were more intense in the laboratory than in the field.
- Recommendation The authors recommend not extrapolating laboratory results to field conditions and vice versa.
- Observation Chlorophyll fluorescence and the xanthophyll cycle showed daily cycles in both laboratory and field.
- Observation UV-absorbing compounds showed daily cycles in the laboratory.
- Observation In the field UV-absorbing compounds showed seasonal changes but no daily changes.
- Observation DNA damage showed daily cycles in the laboratory.
- Observation No DNA damage was detected in the field.
- Observation The sclerophylly index varied only after one month of exposure to supplemental UV-B in the laboratory.
- Observation In the liverwort studied, global UV absorbance was greater in the soluble fraction than in the insoluble fraction.
- Observation In the mosses studied, global UV absorbance showed the opposite pattern: greater in the insoluble fraction than in the soluble one.
- Observation In the liverwort both the soluble and insoluble fractions were sensitive to UV-B.
- Observation In the mosses only the soluble fraction was sensitive to UV-B.
- Mechanism The authors suggest that, if the insoluble fraction is a more efficient UV-B filter than the soluble one, mosses would be more competitive than liverworts in UV-B-rich environments.
