Resumen:
Background and Aims: Wild edible mushroom traditional management
strategies have been described for both highlands and lowlands in
Mexico. It seems that, in the lowlands, the usage of this resource is
lower than in the highlands. Ecological ethnomycology is concerned with
understanding how certain ecological patterns in mushrooms influence
traditional management strategies. In this study we present a comparison
between the edible mushrooms' fruit body availability in two distinct
ecological units: The Highlands of Chiapas and the Lacandon Rainforest.
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. This may
explain why, in the highlands, people use a more diverse array of
species and prefer those of greater biomass. Contrastingly, in the
lowlands less species are used, but they are more abundant and have a
greater spatial and temporal frequency. Our data demonstrate that the
lowlands and agroecosystems are spaces with edible mushroom availability
comparable to that of highland forests.
