Global biodiversity is both declining and being redistributed in response to multiple drivers characterizing the Anthropocene, including synergies between biological invasions and climate change. The Antarctic marine benthos may constitute the last biogeographic realm where barriers (oceanographic currents, climatic gradients) have not yet been broken. Here we report the successful settlement of a cohort of Mytilus cf. platensis in a shallow subtidal habitat of the South Shetland Islands in 2019, which demonstrates the ability of this species to complete its early life stages in this extreme environment. Genetic analyses and shipping records show that this observation is consistent with the dominant vectors and pathways linking southern Patagonia with the Antarctic Peninsula and demonstrates the potential for impending invasions of Antarctic ecosystems.

Biofouling in freshwater and marine environments developed on man-made aquatic surfaces causes significant economic losses. Still, this problem is magnified when it comes to invasive species, such as the golden mussel. One of the alternatives to combat it is the use of antifouling solutions; however, the vast majority focus on solutions for the marine environment.

The oyster Crassostrea gigas larvae in embryonic development stage have been suffering high mortality rate during hatching, which have seriously hindered the sustainable development of oyster seedling industry. This study explored the immune protection and developmental effects of priming with inactivated Vibrio splendidus in oyster larvae at middle umbo stage (10 d post fertilization, dpf). The results showed that the immune system of umbo larvae was activated after pre-immune stimulation with inactivated V.

Bacterial chemotaxis enhances bacterial adaptation to the environment and is important for biofilm formation. Biofilms play a key role in inducing larval settlement and metamorphosis in many marine invertebrates. However, the specific mechanisms by which bacterial chemotaxis influences larval settlement and metamorphosis in mussels remain unknown.

Pursuing effective and biocompatible natural compounds to supplant current biocidal antifouling (AF) technologies remains crucial and challenging. Among natural products hosts, cyanobacteria are recognized as producers of bioactive secondary metabolites that are underexplored in terms of anti-biofilm and AF potential. Nocuolin A, a natural oxadiazine previously isolated and known to be produced by different cyanobacterial strains, has demonstrated bioactive potential, particularly against tumor cell lines.

Biofouling poses a significant economic threat to various marine industries, leading to financial losses that can reach billions of euros annually. This study highlights the urgent need for effective alternatives to traditional antifouling agents, particularly following the global ban on organotin compounds. PTM-346 was isolated from sediment samples on the shores of the Madeira Archipelago, Portugal.
