    Comparative availability of edible mushrooms in the highlands and lowlands of Chiapas, Mexico, and its implications in traditional management strategies Autori: Ruan-Soto, Felipe, Cifuentes Blanco, Joaquín, Garibay Orijel, Roberto, Caballero Nieto, Javier

    “...Our hypothesis was that the fruit body availability is higher in both the highlands and preserved vegetation, which might explain a greater usage in these ecosystems, as well as the opportunistic usage of mushrooms in the lowlands.Methods: During 2009 and 2010, we monitored the fruit body abundance, biomass, spatial and temporal frequencies, as indicators of edible mushroom availability in rectangular transects in three sites per ecological setting (highlands/lowlands) both in preserved vegetation sites and agroecosystems in Chiapas, Mexico.Key results: In the highlands, a greater richness (35 ethnotaxa) and biomass production (12,345.2 g) was recorded, but the lowlands yielded a greater number of fruit bodies (3212) and a higher spatial and temporal frequency (76.6% and 40% respectively).Conclusions: In both ecological settings, edible mushroom availability allow their use; however, it has different ecological traits. ...”
