Resumen
Although the effects of microenvironmental factors on distribution patterns in myxomycetes have been
investigated, studies of the responses of this group of organisms to different regimes of forest disturbance are relatively
few in number. In an effort to understand the implications of
forest fragmentation and habitat loss on myxomycetes, the
project described herein was carried out at the Los Amigos
Biological Station in southeastern Peru. The structure and
composition of assemblages of myxomycetes were investigated in relation to three different forest types and climatic
periods in the area of study. An analysis of the most commonly recorded substrates was carried out as well. The
results suggested that habitat loss, through differences in
forest structure, was the factor determining most of the
differences in fruiting body abundance of myxomycetes
among forest types. In addition, a switch in the ecological
strategy of dispersal seemed to be an important factor accounting for differences in the fruiting body abundance and
structure of assemblages of myxomycetes between collecting periods. This study provides evidence indicating that for
microbial assemblages to maintain the balance of functional
interactions within a particular forest ecosystem, the conservation of the forests themselves should be considered
