“…Multiple linear regression (MLR)-based prediction analysis showed that the selected air quality variables (PM(2.5), PM(10), SO(2), and NO(2)) had a significant impact on the biochemical responses of selected tree spp. including, pH, ascorbic acid (AA), total chlorophyll content (T. Chl.), relative water content (RWC), and dust deposition potential. …”

“…Spearman rank correlation indicated that the NFR was significantly positively correlated with Trichodesmium abundance, salinity, temperature and Secchi depth, but was negatively with turbidity, N/P ratio, NO(x), and chlorophyll a concentration. Our study suggests that distribution and size structure of N(2) fixation off the CE are largely regulated by water mass (intruded Kuroshio water and CDW) movement and associated diazotrophs (particularly Trichodesmium) and nutrient conditions.…”

“…Photosynthesis is generally assumed to be initiated by a single photon(1–3) from the Sun, which, as a weak light source, delivers at most a few tens of photons per nanometre squared per second within a chlorophyll absorption band(1). Yet much experimental and theoretical work over the past 40 years has explored the events during photosynthesis subsequent to absorption of light from intense, ultrashort laser pulses(2–15). …”
