Research on mutualistic and antagonistic networks, such as
plant–pollinator and host–parasite networks, has shown that species
interactions can influence and be influenced by the responses of species
to environmental perturbations. Here we examine whether results obtained
for directly observable networks generalize to more complex networks in
which species interactions cannot be observed directly. As a case study,
we consider data on the occurrences of 98 wood-inhabiting fungal species
in managed and natural forests. We specifically ask if and how much the
positions of wood-inhabiting fungal species within the interaction
networks influence their responses to forest management. For this, we
utilize a joint species distribution model that partitions variation in
species occurrences among environmental (i.e. resource availability) and
biotic (i.e. species-to-species associations) predictors. Our results
indicate that in addition to the direct loss of resource-specialised
species, forest management has indirect effects mediated through
interactive associations. In particular, species with strong associative
links to other species are especially sensitive to forest management.
Fungal dataThis datafile consists of the presence-absence data of 326
wood-inhabiting fungal species (identified as fruit-bodies) found in 22
418 dead wood units from managed and natural forest sites. For each dead
wood unit, the decay stage (scalar from 1 to 5), diameter (in cm), length
(in cm), type (classification according to the diameter) are given. For
each forest site, the management type (managed or natural) and name of the
forest site are given. We surveyed in each forest site 5-10 randomly
located 10 x 10 m sample plots, which are indexed in the "plot"
column.Fungi data.csv
