Shifts in Bacterioplankton Community Structure between Dry and Wet Seasons in a Tropical Estuary Strongly Affected by Riverine Discharge

“…The rather constant values in temperature, are consistent with the known trends in tropical estuaries. The slightly higher values of picophytoplankton during the dry season may be explained by the fact that in the dry season turbidity is lower, allowing a deeper penetration of sunlight (Rochelle-Newall et al, 2011;Seguro et al, 2015;Panhwar and Mairaj, 2022), and that water residence time is longer. This contrasts with the patterns of bacterial abundance, which were higher during the rainy season, particularly in the lower and middle zone of the estuary, suggesting that the entry of freshwater might affect the distribution of bacteria.…”
