| description |
Alsophila firma is a tree fern that is distributed mainly in tropical montane cloud forest (TMCF) and is considered as a threatened species. Arbuscular mycorrrhizal fungi (AMF) have been proposed as an alternative in rescue programs of endangered species. However, our knowledge about diversity of AMF and mycorrhizal status of the species of TMCF is limited. In Mexico TMCF shows different degrees of conservation because of fragmentation and land use change. In this study, we evaluated the level of colonization, richness and abundances of spores of AMF in three fragments with different conservation status: conserved (100 years), secondary vegetation (17 years) and disturbed. For this, soil samples and roots were collected from five individuals of A. firma per site, with at least 100m away from each other; a total of 100cm of roots were analysed per site. Root samples showed AMF and occasionally dark septate fungi (DSF) colonizations. For the overall study, 19 species of AMF were recorded: Gigaspora (7), Acaulospora (4), Glomus (4), Funneliformis (2), Sclerocystis (1) and Scutellospora (1). The dominant species in the three sites were Funneliformis geosporum and Acaulospora scrobiculata. The highest diversity (H’) and evenness (J’) (p<0.05) were found in the conserved site (H’=1.7, J’=0.66), when compared to the secondary vegetation (H’=1.5, J’=0.61), and the disturbed site (H’=0.74, J’=0.41). Statistical analysis showed that the AMF degree of colonization was significantly higher (p<0.05) in the conserved site; although, the disturbed site showed low richness and abundances of AMF, the degree of root colonization did not differ statistically (p<0.05) with the secondary vegetation site. Chao2 (Richness estimation model) showed that the number of analysed samples were sufficient to represent the structure of the AMF communities with values >90%. The present study confirmed that A. firma is a mycorrhizal species that exhibits high levels of colonization even in disturbed sites. We suggest that F. geosporum and A. scrobiculata may have the potential to inoculate the gametophyte and young sporophyte of A. firma, to support restoration programs, because of their abundances and high tolerance to disturbed sites. |

Los hongos micorrízicos arbusculares (HMA) se han propuesto como una alternativa para programas de recuperación de especies nativas en peligro. Sin embargo, sabemos poco sobre la diversidad de HMA y del estatus micorrízico de las especies vegetales del BMM. En México el BMM presenta diferentes grados de conservación debido a la fragmentación y el cambio de uso de suelo. Se evaluó el grado de colonización, riqueza y abundancia de esporas de los HMA presentes en fragmentos de BMM con diferente historia de manejo: conservado (100 años), en recuperación (17 años) y alterado. Se estudiaron muestras de suelo y raíces tomadas de 5 individuos de A. firma por cada sitio, con al menos 100m de distancia entre individuos. Se analizaron en total 100cm de raíz por cada sitio. Las muestras de raíz presentaron colonización principalmente de HMA y ocasionalmente por hongos septados oscuros (HSO). Se encontraron 19 especies: Gigaspora (7), Acaulospora (4), Glomus (4), Funneliformis (2), Sclerocystis (1) y Scutellospora (1). Las especies dominantes en los tres sitios fueron Funneliformis geosporum y Acaulospora scrobiculata. La mayor diversidad (H’) y equitatividad (J’) (p<0.05) se presentaron en el sitio conservado (H’=1.7; J’ 0.66) con respecto al sitio en recuperación (H’=1.5, J’ 0.61) y alterado (H’=0.74, J’=0.41). Los niveles de colonización micorrízica total de raíz fueron estadísticamente mayores (p<0.05) en el sitio conservado. Aunque el sitio alterado presenta una baja riqueza y abundancia de HMA la colonización micorrízica total de raíz no fue estadísticamente diferente (p<0.05) respecto al sitio en recuperación. El estimador Chao2 indica que las muestras analizadas reflejan la estructura general de la comunidad de HMA con valores superiores al 93%. El presente estudio confirma que A. firma es una especie micorrízica con altos niveles de colonización incluso en sitios alterados. Se sugiere que las especies F. geosporum y A. scrobiculata por su alta tolerancia a sitios alterados pueden tener potencial para inocular gametofitos y esporofitos de A. firma para incrementar la supervivencia en programas de restauración.
