L'ecosistema misterioso creato dall'accumulo di oggetti abbandonati oltre il confine dei continenti - Il blog di Jacopo Ranieri

Per l’ira degli dei o il semplice destino dei continenti, l’antico continente emerso di Atlantide fu trascinato negli abissi, senza la benché minima residua considerazione per i suoi condannati abitanti. Un mito possibilmente collegato all’episodio preistorico dell’alluvione zancleana, consistente nell’apertura dello stretto di Gibilterra e il conseguente riversamento dell’Atlantico in quello che oggi costituisce il ...

#Neuston refers to organisms that live at the interface between water and air. They can float on the surface like by-the-wind sailors, use #water tension like water striders, or live near the surface like Pontellid #copepods. Many of these organisms use bright blue astaxanthin pigment for protection from #UV radiation. They are patchily distributed and are an oasis of biomass in low productivity #oceans, yet are still poorly studied. #science

Neuston, we have a problem: why do we know so little about the creatures floating on the ocean surface?

They withstand ocean storms, extreme heat and may impact everything from coral reefs to the deep sea. Why has it taken so long to pay attention to the neuston?

Neuston, we have a problem: why do we know so little about the creatures floating on the #ocean surface? https://www.theguardian.com/environment/article/2024/jun/30/neuston-sea-creatures-ocean-surface-science-study

"Known collectively as the #neuston, these creatures are not tied to any one place. Instead, they move with the wind and the water. Sometimes they gather into huge drifts, living islands of #velella and #bluebottles... At other times they clump together around drifting debris or spread out sparsely over hundreds or even thousands of square kilometres."

Animal #evolution at the #ocean’s water-air interface https://www.cell.com/current-biology/fulltext/S0960-9822(23)01526-9

"#neuston did indeed evolve from ancestors that were substrate-attached but not necessarily to the #seafloor. This means that the neustonic organisms may be derived from #benthic organisms and other organisms that aren’t benthic but still attach to a substrates in the #pelagic zone."

Started From the Bottom…

…now we’re neuston – did ocean surface organisms evolve from their seafloor ancestors?

#Neuston: Of Terms in Biology https://schaechter.asmblog.org/schaechter/2023/09/da-capo-of-terms-in-biology-neuston.html @STCmicrobeblog

"The presence of a gelatinous surface microlayer film had been proposed in 1983, based partly on observations of the slick associated with blooms in the #SargassoSea of the filamentous #cyanobacteria #Trichodesmium... What about the ocean surface film from the #microbial neustonian point of view? It might appear to be an immense #biofilm stretching from horizon to horizon... Estimates of its thickness range from 1 to 50 µm"

[da capo] Of Terms in Biology: Neuston

<p>by Merry  <br /> When I stumbled across the term bacterioneuston, I discovered a whole new world where the air meets the sea. I found that marine neuston had long been used to refer to the diverse flora and fauna inhabiting the topmost 5 cm of the oceans — a distinctly different assemblage than found in the waters below.

The mysterious ecosystem at the ocean’s surface

The mysterious ’neuston’ ecosystem at the ocean’s surface includes keystone organisms like the golden seaweed Sargassum that makes up the Sargasso Sea, floating barnacles, snails, nudibranchs, and cnidarians; this Essay explores threats to its wellbeing and the importance of further research.
