“…Repeated sampling several times during the year could provide a more complete picture of this variability, as discussed in Moreira et al (2007b). Different AMF may have different carbon and other nutrient requirements for sporulation, and this may explain differing AMF phenologies (Violi et al, 2008). Bever et al (1996) reported that host plants determine differences as to when different AMF taxa sporulated.…”

Araucaria angustifolia is an important Brazilian conifer, but it is endangered of extinction due to excessive logging. The objective of the present case study was to survey data on the diversity of AMF in Araucaria angustifolia forests, and to learn whether it is possible to discriminate between the AMF communities associated with natural, introduced, and impacted-byanthropogenic-action ecosystems. Three ecosystems representative of the Campos do Jordão (São Paulo State, Brazil) region were selected, as follows: (i) a native climax forest, with predominance of Araucaria trees, without anthropogenic interference (NF), (ii) Araucaria forest introduced in 1959 (RE), and (iii) Araucaria forest introduced in 1958, submitted to accidental fire in July 2001 (RF). Sampling of rhizosphere soil was performed at a 0-20 cm depth around each Araucaria tree, and 2 m from the trunk, in the months of May and October, 2002. AMF spores were separated from the soil, counted, and taxonomically identified, while the roots were evaluated for mycorrhizal colonization. The ecological indices R (Richness), Is (Simpson's dominance index) and H (Shannon's diversity index) were calculated. All the data were submitted to univariate (two-way ANOVA) and correspondence analysis (CA). Considering both samplings and the three areas, twenty-six AMF species were found, distributed among five genera, Acaulospora and Glomus being the most frequent ones. There were no differences among the three areas for R, Is, and H. CA demonstrated that there is a spatial separation among the three areas, and the AMF that preferentially associated with each area.

“…Sin embargo, en un bosque tropical lluvioso de Ecuador, se demostró que la riqueza de secuencias de grupos taxonómicos de HMA, no difiere en ecosistemas prístinos en comparación con ecosistemas degradados, pero si en su estructura (Haug et al, 2010). De manera opuesta, la riqueza específica basada en morfoespecies de esporas de HMA resultó mayor tras la conversión de BMM a cafetales con diferentes niveles de sombra (Arias, Heredia-Abarca, & Sosa, 2011), asimismo en la conversión de BMM a milpa (Violi et al 2008). Sin embargo, la estructura de los HMA contrasta en los diferentes ecosistemas (Violi et al 2008;Arias et al, 2011).…”

Si bien la diversidad de esporas en el presente estudio fue significativamente mayor en Zongolica, los sitios en recuperación y alterado albergan una alta riqueza de plantas que pueden estar asociados a diferentes especies de HMA como se ha demostrado con análisis de filotipos en ecosistemas de bosques de montaña similares (Kottke et al, 2004;2008).…”

“…La presencia de las dos especies de HMA demuestra que tienen amplia distribución y tolerancia a sitios alterados o de alto impacto antrópico como el sitio de Banderilla. Acaulospora scrobiculata tiene amplia distribución en México y está presente en cultivos agrícolas (Aguirre, Carreón, & Varela 2009;Violi et al, 2008;GuadarramaChávez et al, 2007), vegetación secundaría, selva baja caducifolia (Guadarrama-Chávez, Camargo-Ricalde, Hernández-Cuevas, & Castillo-Argüero 2007), áreas incendiadas (Violi et al, 2008) y suelos contaminados con petró-leo (Franco-Ramírez, Ferrera-Cerrato, VarelaFregoso, Pérez-Moreno, & Alarcón, 2007). Funneliformis geosporum se encuentra en cultivos agrícolas, ecosistemas naturales en selva baja caducifolia, desiertos y dunas costeras (Sigüenza, Espejel, & Allen, 1996;Pezzani, Montana, & Guevara, 2006;GuadarramaChávez et al, 2007).…”

Colonization and structure of arbuscular mycorrhizal fungi community in Alsophila firma (Cyatheales: Cyatheaceae) from a tropical montane cloud forest in Veracruz, México. 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.
