A dataset of seasonal fluctuations of molluscan populations from the southern Gulf of California subtropical arid zone.

The dataset contains insights into the molluscan diversity associated with seagrass and seasonal dynamics in a subtropical arid zone in the southern Gulf of California. The dataset includes the number of species, taxonomy, seasonal abundance data, trophic composition, biomass of molluscan, and biomass of seagrass (). This dataset is referenced in the study titled: "Diversity and seasonal variation of the molluscan community associated with the seagrass in a marine protected area in the southern Gulf of California" (Pérez-Estrada et al., 2023) [1].
