Synopsis

With the aim of analyzing the middle-term variation of hydrological factors and the composition, biomass, and richness of microalgae in the lower basin of the Tuxpan River during the “nortes” season in the region, two sampling surveys were performed in 2018 and 2023, obtaining in situ data (temperature and salinity) and surface samples for analysis of nutrients, Chl-a and microalgae species. In 2018, when high temperatures in a mostly freshwater environment and low nutrient concentrations were recorded, a greater variety of microalgae groups were present (5 clades). In 2023, lower temperature was recorded and a greater influence of seawater farther away from the river mouth was related to a higher diatom species richness, but just two clades of microalgae were recorded. Inter-seasonal variation was identified in the middle-term (cold front season), both in hydrological variables and in the composition, richness, and biomass of microalgae in the Tuxpan River. Saline intrusion, as an effect of the seawater wedge in the lower river basin, could promote changes in the composition of microalgae in the region.

The cover features a photograph of a river surrounded by lush trees at sunset, with sunlight piercing through the branches to create glints of light. Overlaying the image is the title 'Topics of limnological research in Mexico' and the coordinator's name, Alfredo Pérez Morales. The University of Colima editorial seal is displayed at the bottom.
