Warming and acidification effects on biofilm/grazer interaction in an early-stage rocky intertidal community
2016
Anthropogenic carbon dioxide (CO2) emissions are increasing greenhouse effects and changing seawater carbonate chemistry, leading to ocean warming and acidification. Increasing temperature and decreasing seawater pH can potentially interact to cause changes in species interactions and community shifts. To understand how ocean warming and acidification may affect the early stages of an intertidal community in the Mediterranean, we set up an in situ experiment and assessed potential changes in grazer density andbiofilm composition by manipulating temperature on bare rock plots (10x10cm)in two locations along a natural coastal CO2 gradient (Low pH: 7.8 pH, and Ambient:8.1 pH) off Vulcano Islan…
Food Sources for Benthic Grazers in Trophic Networks of Macrophyte Habitats in a Transitional Baltic Ecosystem
2022
In this study, we provide insights into that characteristics of two sites representing different conditions of productivity and salinity impact on trophic network structures of macrophyte habitats and diet of benthic grazers at the active vegetation period in the Curonian Lagoon (southeastern Baltic Sea). Regarding the epiphytic growth, macrophytes were more overgrown in the relatively less productive (northern) site with a muddy bottom and more frequent marine water inflow than in the (southern) site with higher productivity and freshwater sandy habitat. Stable isotope analysis revealed that organisms’ samples from the northern site were more enriched with the heavier carbon isotopes, but …
