Summary: | Maritime pine forests are a major ecosystem throughout the
Portuguese coast and are severely affected by the invasion of <i>Acacia longifolia</i>.
The presented study investigated the diversity of ectomycorrhizal
fungi (ECM) of major plant species in these ecosystems to find possible links
between <i>Pinus pinaster</i>, three native Cistaceae shrubs and the
<i>Acacia</i> invasive species. We successfully identified 13 ECM fungal
taxa. Within those, two species from the order Helotiales were found in all
plant species, and over half of the fungal ECM species found in <i>Pinus
pinaster</i> were also common to the Cistaceae shrubs. Network analysis points to
the Cistaceae shrubs having a central role in these below-ground communities,
therefore enforcing the idea that they are key to these communities
and should not be underestimated. Our results also point to the evolving role
of invasive plant species in the ecosystem dynamics in the rhizosphere, which
host fungal species that are common to native plants, although it is not
yet clear whether these fungal taxa are native or a consequence of the presence of
<i>Acacia longifolia</i>. |
