Fungal community succession and sporocarp production following fire occurrence in Dry Afromontane forests of Ethiopia

Dejene, T., JA Oria-de-Rueda, P Martín-Pinto (2017) - Fungal community succession and sporocarp production following fire occurrence in Dry Afromontane forests of Ethiopia - Forest Ecology and Management

Fire is among the main threats to forest ecosystems in Ethiopia and is affecting the forest biodiversity,
including fungal communities. This study was aimed to examine the effects of fire on macrofungal taxa
richness, diversity and sporocarp production in the Dry Afromontane forests in Ethiopia. Sporocarps were
collected from nine plots (100 m2) established in one- and ten-year-old burned stands, and in an
unburned stands. The data were used to quantify fungal richness and sporocarp fresh weights.
Morphological and molecular analyses were used to identify the fungi. Composite soil samples were also
collected from each stand and used to determine main edaphic explanatory variables for taxa composition.
A total of 61 fungal taxa, belonging to Basidiomycota division were reported, of which 22 were edible.
Fungal diversity, richness and sporocarp production were affected just after the fire. Fungal
community composition was significantly correlated with Organic matter, P and Ca. Generally, the result
is encouraging from the point of view of fungal conservation. It provides novelty information about the
macrofungal communities in Ethiopian dry Afromontane forests, likely including many taxa are still
unknown to science as well as several edible species which could supply complementary incomes for
the rural populations in the study area
