Morfologia fina de quatro espécies de Licmophora (Bacillariophyta, Licmophorales) da Baía do Almirantado e Ilha Elefante, Península Antártica
Palavras-chave:
diatomáceas bentônicas, taxonomia, ultraestrutura.Resumo
Neste artigo, quatro espécies da diatomácea bentônica da Antártica, L. antarctica M. Peragallo, L. belgicae M. Peragallo, L. gracilis (Ehrenberg) Grunow e L. luxuriosa Heiden, são descritas em microscopia eletrônica, baseado em duas coleções de amostras obtidas durante diferentes expedições do Programa Antártico Brasileiro (verão de 1994, e 2003 a 2010). Amostragens do plâncton e bentos foram realizadas em diferentes locais da Ilha Rei George e Ilha Elefante, Península Antártica. Três espécies endêmicas, L. antarctica, L. belgicae e L. luxuriosa, são descritas, incluindo informação sobre estruturas como rimopórtula, poróides e multiscissura. L. gracilis também foi examinada para confi rmar sua identidade. Comparações com espécies próximas também são providenciadas, bem como a distribuição na Península Antártica.
