Abstract EN
This study describes the relationship between mollusks, physicochemical properties of seawater, and sediments under natural conditions of low impact.
Thirty-nine stations were sampled in October 1994 using a Van Veen grab (0.1 m−2).
Temperature, salinity, and dissolved oxygen (DO) concentrations of bottom water were obtained with a CTD.
Organic matter content and sediment grain analysis were determined.
A total of 836 mollusks were collected.
Gastropoda was the most abundant (52%) and diverse class with 27 genera, followed by Bivalvia with eight genera and Scaphopoda with only one genus.
According to CCA analysis, dominant mollusks were significantly related with high DO concentrations.
Donax, Natica, Acteocina, Bulla, Anachis, Odostomia, and Crucibulum can be classified as sensitive genera because they were found mainly in high oxygen concentrations (3.1–5.6 mL L−1); on the other hand, Cardiomya, Nuculana, Laevicardium, Chione, Truncatella, and Dentalium can be classified as tolerant genera (1.0–5.6 mL L−1).
Todos Santos Bay hosts a diverse malacological fauna (36 genera); our results show that the dominant genera were mainly related to high dissolved oxygen concentrations.
Mollusks can be a useful tool in environmental monitoring programs related with oxygen depletion in coastal areas.
