    Seawater carbonate chemistry and fish communities properties off CO2 seeps in Japan (2020)

    Description: Ocean acidification will likely change the structure and function of coastal marine ecosystems over coming decades. Volcanic carbon dioxide seeps generate dissolved CO2 and pH gradients that provide realistic insights into the direction and magnitude of these changes. Here, we used fish and benthic community surveys to assess the spatio-temporal dynamics of fish community properties off CO2 seeps in Japan. Adding to previous evidence from ocean acidification ecosystem studies conducted elsewhere, our findings documented shifts from calcified to non-calcified habitats with reduced benthic complexity. In addition, we found that such habitat transition led to decreased diversity of associated fish and to selection of those fish species better adapted to simplified ecosystems dominated by algae. Our data suggest that near-future projected ocean acidification levels will oppose the ongoing range expansion of coral reef-associated fish due to global warming.

    Density of the painted comber Serranus scriba, a goby predator, at an ambient (∼380 μatm) and high (∼850 μatm) CO2 sites off a volcanic CO2 vent in Vulcano island, Italy (2023)

    Description: This data set contains the density of the painted comber predator Serranus scriba at two CO2 sites (Ambient and High CO2). The density of the predator was visually assessed in replicate 10 × 2 m belt transects at 1–3 m depth on mixed sandy/rocky bottoms in the two CO2 condition sites (ambient, n = 19; high-CO2, n = 22).

    Anti-predator responses of the Mediterranean anemone goby, Gobius incognitus, acutely and chronically exposed to ambient (∼380 μatm) and high (∼850 μatm) CO2 sites off a volcanic CO2 vent in Vulcano island, Italy (2023)

    Description: An in situ reciprocal transplant experiment was carried around a volcanic CO2 vent (Vulcano Island, Aeolian Archipelago, Italy) to evaluate the anti-predator responses of an anemone goby species exposed to ambient (∼380 μatm) and high (∼850 μatm) CO2 sites during two sampling surveys on May 17th – June the 2nd 2019, and 9–18 September 2019. Behavioral observations followed a well-established protocol adopted previously for other fish species, which consisted in recording gobies responses before and after the presentation of a predator (i.e. predator stimulus). Specifically, for each replicate a 4-min pre-stimulus presentation period was followed by a 4-min post-stimulus presentation period during which each fish was exposed to the visual and olfactory cues of an adult painted comber S. scriba. During the pre- and the post-stimulus periods we measured: the activity level, as the amount of time (sec) spent by the fish swimming in the entire experimental compartment; (ii) the time spent (sec) by the fish actively swimming or resting at 〈20 cm from the predator compartment (i.e. the predator zone) and at 〉20 cm from the predator compartment (no predator zone); (iii) the shelter use, as the total time the fish spent near the anemone (i.e. less than 5 cm); (iv) the minimum approach distance, as the mean smallest distance (cm) of the fish centroid from the shelter (A. viridis).

    Carbonate chemistry of ambient (∼380 μatm) and high (∼850 μatm) CO2 sites off a volcanic CO2 vent in Vulcano island, Italy (2023)

    Description: Carbonate chemistry measured at two CO2 sites characterized by different pCO2 regimes (high pCO2 and ambient pCO2) of Vulcano Island (year 2019). Multiple measurements of salinity, temperature (T °C) and pH were carried out daily in each experimental site (between 10:00-17:00 h) on the same day the behavioural trials were performed. A multi- parametric probe (YSI 556 MPS, YSI Inc. Yellow Springs, OH) was used to measure salinity and pH and temperature (°C). A fixed Total Alkalinity of 2500 μmol kg− 1 (assumed for this study), pHNBS temperature and salinity were used to calculate the pCO2 levels using the software CO2SYS (Pierrot et al., 2006) with dissociation constants for carbonate from Mehrbach et al. (1973) refitted by Dickson and Millero (1987), and for KSO4 from Dickson (1990).
