Meet the team behind this project.

Jesús Aboal, as part of the USC “A Ponte do Ensino Medio” Program (https://www.usc.gal/es/campusterra/ponte-ensino), gave a talk about our research project on Wednesday, November 24th, 2025, […]
On July 23rd, we headed to Testal Beach (Ría de Noia y Muros) to determine the chlorophyll fluorescence and spectral reflectance of Fucus vesiculosus specimens.
On June 27rd, we visited Testal Beach (Ría de Noia y Muros) to collect Fucus vesiculosus specimens at different intertidal heights.
Carme Pacín attended the 14th International Temperate Reefs Symposium, held on July 3th-5th 2025, in Brest, France. During the event, she presented the preliminary results of […]

Heavy metal (HM) pollution threatens biodiversity due to its high toxicity and persistence in natural ecosystems. Brown macroalgae, particularly Fucus vesiculosus, can accumulate and tolerate substantial […]
Led by Antón Vázquez-Arias, we collected F.vesiculosus for transplants at 22 locations in Galicia, using automatic samplers. Preliminary results will soon reveal the relationship between PTEs in algae and water.
Teresa Boquete and Carme Pacín presented posters on epigenetics and genetic diversity in Fucus vesiculosus at the IBC 2024 in Madrid, taking the opportunity for scientific collaboration.
In July 2024, we sampled F. vesiculosus transects, measuring chlorophyll fluorescence and spectral reflectance to optimize the methodology and analyze relationships between composition, PTEs, and ecophysiological variables.
In July 2024, we sampled 100 individuals of F. vesiculosus in an intertidal system to analyze how tidal height affects their chemical composition, PTE concentrations, and morphology. Results forthcoming.
Antón Vázquez-Arias and Carme Pacín attended the 8th ISAP 2024 in Porto, presenting studies on the distribution of elements in algae using Nano-SIMS and changes in cell walls with FTIR.

Marine ecosystems and the impact of heavy metal pollution (HM).

Marine ecosystems, especially those in coastal areas, are particularly vulnerable to heavy metal (HM) pollution since they are subject to both land- and ocean-based pollution sources. Due to their toxicity, persistence, and capacity to biomagnify in the food chain, HMs pose an important threat through lethal and sub-lethal effects at the individual level that might have far-reaching consequences at higher hierarchical levels: populations, communities, and even entire ecosystems.

The cascading effects of pollution can thus jeopardize ecosystems' integrity and undermine their resilience, especially when they impact species with critical ecosystem roles, like macroalgal foundation species.
