| contents | New records of marine choanoflagellates off the Chilean coast Juan Kuznar Katia Soto-Liebe Gloria Collantes Ciencias de la Tierra virus Chile bacteria ballast water epifluorescence This is the first report of planktonic choanoflagellates from the Chilean coast, relating their abundance withthat of bacteria and viruses. Surface water samples were taken off Antofagasta, Montemar, and Puerto Montt and samplesfrom ballast tanks were also analyzed. The choanoflagellates were identified following morphological type descriptions.Viruses and bacteria were stained with SYBR Green and choanoflagellates, bacteria, and viruses were counted simultaneouslyusing red autofluorescence for the former and green fluorescence for the latter two. Six species of Acanthoecidaewere observed for the first time in Chilean waters: Calliacantha multispina (0.3·103 L-1), Acanthocorbis apoda, Stephanoecadiplocostata (2.0·103 L-1), Crinolina isefiordensis, Parvicorbicula superpositus, and Pleurasiga minima (5.0·103L-1). The concentrations of bacteria (1.1·106-4.5·10 6) and viral-like particles (VLPs) (7.9·10 6-21·10 6) agreed with thosetypically found in marine coastal waters. In addition, Acanthocorbis asymmetrica was found in ballast waters, where itshigh concentration (20·103 L-1) likely resulted from the particular physical and biological environment therein. 2007 artículo científico 0716-1069 https://www.redalyc.org/articulo.oa?id=45635211 en http://www.redalyc.org/revista.oa?id=456 Investigaciones Marinas application/pdf Pontificia Universidad Católica de Valparaíso Investigaciones Marinas (Chile) Num.2 Vol.35 |
