The total quantity of 18S sequences identified in Mar Menor and Albufera were 28 (,five of total SSUs) and 22 (,five of total SSUs) respectively. The main eukaryote identified in Mar Menor was Alexandrium (,18 , n55) a marine armored dinoflagellate that produces neurotoxins that lead to paralytic shellfish poisoning. Alexandrium is well known in coastal lagoons inside the Mediterranean69 and has each autotrophic and heterotrophic species. Alexandrium blooms are dangerous and are famously known as red tides. The toxins it produces can have adverse effects when consumed by humans, usually in the type of contaminated seafood (shellfish, fish etc)70. Additionally, these blooms are typical in coastal habitats, and have an effect on marine trophic structure, boost mortality of marine fish, birds and mammals and disrupt recreational activities70. Dinoflagellate blooms are usually [https://britishrestaurantawards.org/members/singer20europe/activity/363629/ https://britishrestaurantawards.org/members/singer20europe/activity/363629/] correlated with improved levels of lowered nitrogen sources, particularly ammonia and urea (at the least for Alexandrium)71. Photosynthetic dinoflagellates can supplement photosynthetic growth by organic sources along with the increase inside the levels of inorganic nutrients (especially nitrogen and phosphorus)72, coupled by their capacity to produced paralyzing toxins make them robust competitors in eutrophic systems, affecting multicellular and unicellular life alike73. On the other hand, toxin production by Alexandrium is inconsistent, and not all species are toxic. On top of that to Alexandrium, other dinoflagellates had been also detected (e.g. Gymnodinium, Protoceratium). An additional abundant organism present by 18S rRNA in Mar Menor was Chrysochromulina (n54), that is a haptophyte from the class Prymnesiophyceae. Haptophytes (e.g Chrysochromulina, Phaeocystis, Prymnesium), are all bloom forming organisms. The certain feature of haptophytes is definitely the presence of a haptonema, a flagella-like (though only superficially), retractile, coiled protuberance, performing a number of functions (e.g. sensory responses, prey capture)74. Chrysochromulina can also be photosynthetic, and (like some Alexandrium species), can supplement photosynthetic growth by mixotrophic feeding. Indeed, some Chrysochromulina species are truly euryhaline also, having a a lot larger level of optimum salinity for growth75 than marine levels. Within a microscopic examination and enumeration on the planktonic species, we were able to recognize numerous abundant diatoms (e.g.SCIENTIFIC REPORTS | 2 : 490 | DOI: ten.1038/srepCyclotella, Entomoneis, Nitszchia). Cyclotella was identified by its 18S rRNA sequence within the metagenomic data also. It is actually a well-known abundant centric diatom.
