Red Sea Plume
"Asparagopsis delilei Montagne, 1841 Asparagopsis sandfordiana Harvey, 1855 Asparagopsis sanfordiana Harvey, 1855 Dasya delilei Montagne, 1841 Falkenbergia hillebrandii (Bornet) Falkenberg, 1901 Fucus taxiformis Delile, 1813 Lictoria taxiformis (Delile) J. Agardh, 1841 Polysiphonia hillebrandii Bornet, 1883"
Asparagopsis taxiformis (red sea plume or limu kohu), formerly A. sanfordiana, is a species of red algae, with cosmopolitan distribution in tropical to warm temperate waters. Researchers have demonstrated that feeding ruminants a diet containing 0.2% A. taxiformis seaweed reduced their methane emissions by nearly 99 percent.
Type Description
Gametophyte specimens do not have thalli, modified stolons with apically arranged harpoon-like hooks, and a distinct rhizomatous system.
Habitat
Tropical and subtropical regions.
Reproductive Information
The main reproductive structures are the cystocarps (female) and spermatangia (male). The cystocarps are subspherical to ovate in shape, and grow at the apices of the short branches. The structures are red in color, while the spermatangia are cylindrical in shape, and also grow at the apices.
Lifecycle
Like many red algae, A. taxiformis has a haplodiplophasic lifecycle, with each phase morphologically distinct. The species' diploid stage was initially described as Falkenbergia hillebrandii (Bornet) Falkenberg 1901 because it was thought to be a separate species.
Nutrition Information
Photosynthesis
General Impact Information
The genus Asparagopsis is known to be an important, highly invasive species. Both species A. armata and A. taxiformis are included on the list of the "worst invasive alien species threatening biodiversity in Europe and Mediterranean Sea".[8] Asparagopsis armata, a native species from Australia and New Zealand, has spread its population strictly in the temperate region, particularly in Europe. Due to its invasive capacity, the presence of Asparagopsis has an effect on the distribution and abundance of other marine organisms, such as peracarid crustaceans.[9] Assemblage of epifaunal communities in the Mediterranean Sea shows a decrease in diversity and homogenised distribution compared with other associated seaweeds present in the area. The structure of the associated macrofauna (species composition, variability among samples, and relative abundance of the species) was also different in a habitat dominated by A. armata and A. taxiformis. This further validates the capacity of genus Asparagopsis to be successful and influential bio-invaders of different habitats.

General Pathway Information
Mediterranean Sea before the opening of the Suez Canal, and its current distribution is likely the result of several introduction events including possible Lessepsian migration.

IMPACT INFORMATION
Asparagopsis cinsi, önemli ve yüksek invaziv bir tür olarak bilinmektedir. Hem A. armata hem de A. taxiformis türleri, "Avrupa ve Akdeniz'deki biyoçeşitliliği tehdit eden en kötü invaziv yabancı türler" listesine dahil edilmiştir. Asparagopsis armata, Avustralya ve Yeni Zelanda'dan gelen bir yerli tür olup, popülasyonunu özellikle Avrupa'da olmak üzere ılıman bölgelerde genişletmiştir. İnvaziv yeteneği nedeniyle Asparagopsis'un varlığı, diğer deniz organizmalarının dağılımı ve bolluğu üzerinde etkisi olan perakarid kabuklular gibi deniz organizmalarını etkiler. Akdeniz Denizi'ndeki epifonal toplulukların bir araya gelmesi, bölgedeki diğer ilişkili deniz yosunları ile karşılaştırıldığında çeşitlilikte bir azalmayı ve homojenleşmiş bir dağılımı gösterir. A. armata ve A. taxiformis'in hakim olduğu bir habitatın, ilişkili macrofauna yapısının (tür kompozisyonu, örnekler arasındaki değişkenlik ve türlerin göreceli bolluğu) da farklı olduğu gözlemlenmiştir. Bu durum, Asparagopsis cinsinin farklı habitatlarda başarılı ve etkili biyo-invazörler olma kapasitesini daha da doğrular.
