DOI: 10.1111/php.13413
Abstract: Although pulse amplitude modulation (PAM) fluorometry has revolutionized photosynthetic studies, Photosynthetic Electron Transport Rate (ETR) cannot be measured using PAM technology in some organisms. We compare in vivo absorbance information on a selection of photosynthetic… read more here.

DOI: 10.1111/php.13693
Abstract: Nonphotochemical quenching (NPQ) is known to depress in vivo fluorescence (IVF) of chlorophyll a (Chla) in aquatic environments, which makes it difficult to interpret the hour‐to‐hour variations in Chla measured by in situ fluorometers. We… read more here.
