Melo, C.D., Luna, S.D., Krüger, C., Walker, C., Mendonça, D., Fonseca, H.M.A.C., Jaizme-Veja, M.C. & Câmara Machado, A. (2017) Arbuscular mycorrhizal fungal community composition associated with Juniperus brevifolia in native Azorean forest.
Acta Oecologica-International Journal of Ecology, 79, 48-51. DOI:10.1016/j.actao.2016.12.006 (IF2017 1,615; Q3 Ecology)The communities of glomeromycotan fungi (arbuscular mycorrhizal fungi, AMF) under native Juniperus brevifolia forest from two Azorean islands, Terceira and São Miguel, were compared, mainly by spore morphology, and when possible, by molecular analysis. Thirty-nine morphotypes were detected from 12 genera. Glomeromycotan fungal richness was similar in Terceira and São Miguel, but significantly different among the four fragments of native forest. Spore diversity and community composition differed significantly between the two islands. The less degraded island, Terceira, showed 10 exclusive morphotypes including more rare types, whereas the more disturbed forest on São Miguel showed 13 morphs, mostly of common types. Forests from Terceira were dominated by Acaulosporaceae and Glomeraceae. Whereas members of Acaulosporaceae, Glomeraceae and Ambisporaceae were most frequent and abundant in those from São Miguel. Spore abundance was greatest on Terceira, and correlated with soil chemical properties (pH), average monthly temperature and relative humidity.
