Edaphic cyanobacterial community of post-fire soils in Sierras Chicas of Córdoba province, Argentina
Cyanobacteria are oxygenic phototrophic organisms that possess a high adaptive capacity to different environments, allowing them to pioneer terrestrial ecosystems. The objective of this study was to compare the cyanobacterial community in two areas of secondary mountain forest: one seven days after...

The objective of this study was to compare the cyanobacterial community in two areas of secondary mountain forest: one seven days after a fire (post-fire soil) and another nearby without fire (control soil). The collected samples were cultivated for 8 weeks under controlled conditions. A total of 35 taxa were identified: 2 unicellular, 24 filamentous without heterocytous, and 9 with heterocytous cyanobacteria; 13 of them represent the first record for soils in Córdoba. Microcoleus vaginatus was the most frequent taxon, along with Scytonema hoffmannii, Desmonostoc muscorum, and Nostoc commune, which persisted until the end of the experiment. The presence of exclusive organisms such as Calothrix brevissima, Chlorogloeopsis fritschii, and Cylindrospermum muscicola in the control soils highlights their sensitivity to this type of disruptive event in the community. The availability of nitrogen, CO content, and pH are the physicochemical soil variables that define the community structure. This work is contributing to increase our knowledge of soil restoration after forest fires. Las cianobacterias son los organismos fototróficos oxigénicos que poseen una alta capacidad adaptativa a diferentes ambientes, lo cual les permite ser pioneros en los ecosistemas terrestres. El objetivo del trabajo fue comparar la comunidad de cianobacterias en dos zonas de bosque serrano secundario, uno a siete días de ocurrido un incendio (suelo postfuego) y otra próxima sin incendio (suelo testigo). Las muestras extraídas se cultivaron durante 8 semanas en condiciones controladas. Se identificaron un total de 35 taxones: 2 unicelulares, 24 filamentosas sin heterocitos y 9 con heterocitos; 13 de ellos constituyen primera cita para suelos de Córdoba. Microcoleus vaginatus fue el taxón más frecuente, junto con Scytonema hoffmannii, Desmonostoc muscorum y Nostoc commune permanecieron hasta finalizar el ensayo. Se destaca la presencia de organismos exclusivos tales como: Calothrix brevissima, Chlorogloeopsis fritschii y Cylindrospermum muscicola en los suelos testigos, serían los taxones sensibles a este tipo de eventos disruptivos en la comunidad. La disponibilidad de nitrógeno, contenido de CO y pH son las variables físico-químicas del suelo que definen la estructura de la comunidad. Se considera que este trabajo aporta valiosa información para el avance del conocimiento de la restauración de suelos luego de los incendios forestales.
