O QUE SIGNIFICA PERIPHYTON EM INGLÊS
Periphyton
O periphíton é uma mistura complexa de algas, cianobactérias, micróbios heterotróficos e detritos que estão ligados a superfícies submersas na maioria dos ecossistemas aquáticos. Ele serve como uma importante fonte de alimento para invertebrados, girinos e alguns peixes. Também pode absorver contaminantes, removê-los da coluna de água e limitar seu movimento através do meio ambiente. O perifiótico também é um indicador importante da qualidade da água; As respostas desta comunidade aos poluentes podem ser medidas em uma variedade de escalas que representam mudanças fisiológicas para o nível comunitário. Assim, o perifióto tem sido usado frequentemente como um sistema experimental, por exemplo, estudos de tolerância comunitária induzidos pela poluição. As comunidades de Periphyton são usadas em sistemas de produção de alimentos para aquicultura para remoção de poluentes sólidos e dissolvidos. O seu desempenho em filtração é estabelecido e sua aplicação como alimentação aquacultural está sendo pesquisada. O risco de periphyton decorre da urbanização. Aumento dos níveis de turbidez associados à expansão urbana pode sufocar o periphyton causando seu desprendimento das rochas em que vive. Pode ser importante para a remoção de produtos químicos prejudiciais e reduzir a turvação.
definição de periphyton no dicionário inglês
A definição de periphyton no dicionário é organismos aquáticos, como certas algas, que vivem unidas a rochas ou a outras superfícies.
