| description | The purpose of this study was to increase knowledge of the nitrogen-fixing cyanobacteria communities of Chilean rice fields. To this end, we sampled 34 rice fields situated between latitudes 34° 30' and 36° 36' S in central Chile. At each site, two water samples and one soil sample were taken. Samples were fixed in 4 % formalin before taxonomic determination. A total of 12 filamentous heterocystous taxa were determined, nine of which have not previously been recorded in Chile. For each taxon, a description based on morphological and reproductive characters was made and recorded along with information on the geographical distribution in the study area<br>El propósito de este estudio fue incrementar el conocimiento de las comunidades de cianobacterias fijadoras de nitrógeno en los campos arroceros chilenos. Para este fin, nosotros muestreamos 34 arrozales situados entre latitudes 34° 30' y 36° 36' S en Chile central. En cada sitio, se tomaron 2 muestras de agua y una de suelo. Las muestras fueron fijadas en formalina al 4 % y fueron usadas para la determinación taxonómica. A total de 12 taxa filamentosas heterocísticas fueron determinados, nueve de los cuales no han sido previamente registrados en Chile. Para cada taxón, se hizo una descripción basada en caracteres morfológicos y reproductivos y se registró información acerca de la distribución geográfica en el área de estudio |
