CHE SIGNIFICA PERIPHYTON IN INGLESE
periphyton
Periphyton è una miscela complessa di alghe, cianobatteri, microbi eterotrofici e detriti che sono collegati a superfici sommerse nella maggior parte degli ecosistemi acquatici. Serve come fonte di cibo importante per gli invertebrati, i tadpoles e alcuni pesci. Può anche assorbire i contaminanti, rimuoverli dalla colonna d'acqua e limitarne il movimento attraverso l'ambiente. Il periphyton è anche un indicatore importante della qualità dell'acqua; Le risposte di questa comunità agli inquinanti possono essere misurate in una varietà di scale che rappresentano fisiologiche a cambiamenti a livello comunitario. Quindi il periphyton è stato spesso utilizzato come sistema sperimentale in, ad esempio, studi di tolleranza comunitaria causati dall'inquinamento. Le comunità di Periphyton sono utilizzate nei sistemi di produzione alimentare dell'acquacoltura per la rimozione di sostanze inquinanti solide e dissolte. La loro prestazione nella filtrazione è stabilita e la loro applicazione come alimentazione acquacoltura è stata ricercata. Un rischio per il periphyton deriva dall'urbanizzazione. L'aumento dei livelli di torbidità associati a sprawl urbano può disturbare il periphyton causando il suo distacco dalle rocce su cui vive. Può essere importante per la rimozione di sostanze chimiche nocive e la riduzione della torbidità.
definizione di periphyton nel dizionario inglese
La definizione di periphyton nel dizionario è organismi acquatici, come certe alghe, che vivono attaccati a rocce o altre superfici.
