Mutualistic interactions like those established between plants and
mycorrhizal fungi or seed dispersers are key drivers of plant population
dynamics and ecosystem functioning, however, these interactions have
rarely been explored together. We assembled a tripartite
fungi-plant-disperser network in the Gorongosa National Park - Mozambique,
to test 1) if the diversity and importance of plant mutualists above- and
belowground are correlated, and 2) whether biotically and abiotically
dispersed plants are associated with similar or distinct arbuscular
mycorrhizal fungi (AMF) communities. We quantified seed dispersal by
animals during one year and characterized the community of 26 common plant
species. Sixteen plant species were dispersed by 15 animals and colonized
by 48 AMF virtual taxa (VT), while the remaining ten plant species were
not dispersed by animals and associated with 34 AMF VT. We found no
evidence for a correlation between the number of plant partners above- and
belowground or on plant specialization on both types of partners. We also
found no evidence for differentiation of AMF communities between
biotically and abiotically dispersed plants. Altogether, these results
suggest that the establishment of plant interactions with seed dispersers
and mycorrhizal fungi are largely independent and that both biotically and
abiotically dispersed plants seem to associate with similar communities of
AM fungi. Correia et
