DIATOMEAS (BACILLARIOPHYCEAE) DE ZONAS ANDINAS DEL NORTE DE CHILE: NUEVA LOCALIDAD GEOGRáFICA PARA HALOROUNDIA SPECIOSA (HUSTEDT) DIAZ ET MAIDANA
Rivera,Patricio; Cruces,Fabiola;
Gayana. Botánica , 2009, DOI: 10.4067/S0717-66432009000200013
Abstract: this note reports the first finding of haloroundia speciosa (hustedt) diaz et maidana (bacillariophyceae) in a sample collected from the salar de aguas calientes, loa province, northern chile (23°30's; 67°33'w). this species is restricted to the andes mountains. comments about its morphological features and geographical distribution in north andean areas are given.
THALASSIOTHRIX SPATHULATA HASLE (THALASSIONEMATACEAE, BACILLARIOPHYCEAE): PRIMER REGISTRO PARA LA FLORA DIATOMOLOGICA MARINA DE CHILE
Rivera,Patricio; Cruces,Fabiola;
Gayana. Botánica , 2005, DOI: 10.4067/S0717-66432005000100009
Abstract: we report the first finding of thalassiothrix spathulata in the marine phytoplankton of chile. the species was common in samples collected between 18o16's and 28o06's. principal morphological features are described and illustrated
TRANSFER OF ACHNANTHES LOOSERI FRENGUELLI TO THE GENUS PLANOTHIDIUM
Rivera,Patricio; Cruces,Fabiola;
Gayana. Botánica , 2009, DOI: 10.4067/S0717-66432009000100010
Abstract: se estudió el material tipo de achnanthes looseri frenguelli mediante técnicas de microscopía fotónica y electrónica de barrido. se propone el traslado de la especie al género planothidium. se designa el lectotipo y se entrega una diagnosis corregida del taxón.
FRAGILARIA STRIATULA LYNGBYE: UNA DIATOMEA MARINA MUY POCO CONOCIDA PARA CHILE
Rivera,Patricio; Cruces,Fabiola;
Gayana. Botánica , 2002, DOI: 10.4067/S0717-66432002000100006
Abstract: although the marine species fragilaria striatula lyngbye is widely distributed in the north atlantic and the arctic, has rarely been reported from the southeastern pacific coasts of chile. using material deposited at the diatom collection of the university of concepcion, chile, the morphological features of this taxon were observed and recorded under light and electron microscopes. the specimens studied were collected between 20°13's and 53°39's, revealing a wide distribution along the chilean coast, especially as an epiphyte on larger algae
Primer registro para Chile de las diatomeas marinas Nitzschia amabilis, Nitzschia elegantula y Chaetoceros muelleri var. subsalsum
Rivera,Patricio; Cruces,Fabiola;
Revista de biología marina y oceanografía , 2011, DOI: 10.4067/S0718-19572011000100015
Abstract: the marine small diatoms nitzschia amabilis, nitzschia elegantula and chaetoceros muelleri var. subsalsum are reported for the first time from chilean coastal waters. a short diagnosis is included for each taxon, and photomicrographs provide information about the main morphological characteristics.

FRAGILARIA STRIATULA LYNGBYE: UNA DIATOMEA MARINA MUY POCO CONOCIDA PARA CHILE FRAGILARIA STRIATULA LYNGBYE: A LITTLE KNOWN MARINE DIATOM FROM CHILE
Patricio Rivera,Fabiola Cruces
Gayana. Botanica , 2002,
Abstract: Aunque la especie marina Fragilaria striatula Lyngbye está ampliamente distribuída en aguas del Atlántico Norte y del Artico, es muy poco conocida para las aguas del Pacífico Sur Oriental de Chile. Sobre la base de material depositado en la Colección Diatomológica de la Universidad de Concepción, Chile, se observó y fotografió las características morfológicas de este taxon en los microscopios fotónico y electrónicos. Los especímenes estudiados fueron recolectados entre los 20°13'S y los 53°39'S, revelando una gran distribución a lo largo de la costa de Chile, especialmente como epífita de algas superiores Although the marine species Fragilaria striatula Lyngbye is widely distributed in the North Atlantic and the Arctic, has rarely been reported from the southeastern Pacific coasts of Chile. Using material deposited at the Diatom Collection of the University of Concepcion, Chile, the morphological features of this taxon were observed and recorded under light and electron microscopes.
