Resumo(s)
Asparagopsis (Bonnemaisoniaceae, Rhodophyta) species are distributed in most temperate and tropical waters of the world,
where they are considered an iconic invader. Despite a low number of species in the genus, Asparagopsis armata and A.
taxiformis are considered species complexes, revealing remarkable genetic diversity in native and introduced distribution ranges. Macroscopic life stages that characterize the life cycle, gametophytes, and tetrasporophytes, present diferent
morphologic, photosynthetic, physiological, and ecological features, which may aid in the course of an invasive process.
Asparagopsis presence lowers diversity and abundance of native macroalgal communities. Despite hosting a relatively high
number of epiphytes and epifauna, lower numbers are consistently found in these invasive species when compared to native
fora. The chemical composition of A. armata and A. taxiformis and thus, its commercial applications have been studied
since the 1970s. Recently, the discovery of its properties as a potent methane release inhibitor from ruminant animals has
boosted a renewed scientifc, media, and commercial interest in the genus. Sourcing biomass remains a challenge, and while
techniques of cultivation are available, more needs to be done to reach the scale needed to ft such large-volume application.
Much is yet to be expected from this red algal genus.
