Long-term baseline data that allow tracking how predator–prey interactions have responded to intensifying human impacts are often lacking. Here, we assess temporal changes in benthic community composition and between drilling predatory gastropods their molluscan prey using the Holocene fossil record of shallow northern Adriatic Sea, which is characterized by a long history transformation. Molluscan assemblages differ Isonzo Po prodelta, but both show consistent trends abundance dominant species. Samples mollusc collected at high stratigraphic resolution indicate frequencies drastically declined prodelta since mid-twentieth century, while weaker trend more condensed sediments not statistically significant. The decrease predation intensity turnover linked loss increased relative less-preferred during most recent decades. Our results align with showing substantial depletion marine resources higher trophic levels region strong simplification food web initiated late nineteenth century accelerated further century.

Echinoids are an integral part of present-day and ancient marine trophic webs, they host a variety mutualistic, commensalistic, parasitic epibionts on their spines test. Cidaroid echinoid (slate pencil urchins) in particular commonly colonized by epizoans. Eucidaris the western Atlantic eastern Pacific today notable for frequency intensity calcifying, non-calcifying, galling colonization spines. While moderate levels spine may provide camouflage other benefits to host, high density encrusters instead reduce fitness, is invariably parasitic. Significant environmental changes equatorial sub-equatorial necessitate paleobiological approach constrain timing epibiosis . Here, we compare rates populations with ancestral Pliocene assemblages. We find that show no evidence galling, significantly less than descendants both Pacific. This holds true even after accounting taphonomic processes would preferentially erase non-calcifying colonization. propose relatively recent development reflect human-induced habitat degradation region, underscoring need further investigation into this biotic interaction.
