Meet the team behind this project.

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.
During April and May 2024, Teresa Boquete, Patricia Hermida Sestayo, and Dr. Pilar Díaz Tapia conducted sampling at three locations to study sex ratios in F. vesiculosus. They will provide updates after the elemental analysis is complete.
Carme Pacín conducted research at the University of Western Australia on changes in the genetic diversity of Fucus vesiculosus over 30 years, linking them to metal levels in polluted areas.
In February 2024, Teresa, Antón, and Jesús spent 96 hours at the ESRF scanning Fucus vesiculosus, localising chemical elements at the subcellular level. The results are under review for publication.
Antón Vázquez-Arias completed a research stay at the Marine Core Research Institute in Japan, investigating the localization of elements in marine algae using NanoSIMS. The results are forthcoming for publication.

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.
