Population origin determines the adaptive potential for the advancement of flowering onset in Lupinus angustifolius L. (Fabaceae). [PDF]

Evol Appl, 2023
Abstract In the present framework of global warming, it is unclear whether evolutionary adaptation can happen quick enough to preserve the persistence of many species. Specifically, we lack knowledge about the adaptive potential of the different populations in relation to the various constraints that may hamper particular adaptations. There is evidence

Monte Carlo Evaluation of Uncertainties of UV Spectra Measured With Brewer Spectroradiometers

Journal of Geophysical Research: Atmospheres, Volume 128, Issue 24, 27 December 2023., 2023
Abstract Precise spectral ultraviolet (UV) measurements are needed to ensure human protection as well as to support scientific research. Quantifying the uncertainty of the UV spectra recorded is crucial to evaluate the quality of the measurements which is needed, in turn, for the assessment of their reliability.
