Diatomáceas epifíticas (Diatomeae) no reservatório urbano Piraquara II, estado do Paraná

Autoria SCIMAGO INSTITUTIONS RANKINGS

Resumo

Realizamos um estudo taxonômico das diatomáceas epifíticas nas macrófitas: Polygonum hydropiperoides, Ludwigia peruviana e Alternanthera philoxeroides, coletadas no reservatório Piraquara II, uma represa urbana mesotrófica inundada em 2009, localizado no estado do Paraná. Um total de 135 táxons infragenéricos foi determinado, entre os quais cinco foram citações pioneiras para o Estado. Ilustrações, limites métricos, merísticos e referências taxonômicas para cada táxon foram providenciadas. Também, dados sobre formas de vida e frequência das espécies foram adicionados. As diatomáceas mais frequentes totalizaram 15,3% dos táxons determinados e as espécies esporádicas representaram 54%. Achnanthidium minutissimum (Kützing) Czarnecki and Brachysira neoexilis Lange-Bertalot ocorreram em mais de 90% das amostras analisadas. Dentre as diatomáceas muito frequentes encontram-se outras espécies de Achnanthidium, Fragilaria e Eunotia. Discostella stelligera (Cleve & Grunow) Houk & Klee, uma diatomácea solitária, e Aulacoseira tenella (Nygaard) Simonsen, com cadeias curtas, são espécies livres que se emaranham entre as diatomáceas do biofilme.
