Unveiling the interactions between invasive Pinus contorta, mycorrhizal communities, and local ecological diversity in Patagonia, Argentina.
The phenomenon of invasive species threatens local biodiversity and native ecosystems around the global. Often introduced intentionally, many non-indigenous species spread from their point of introduction into local ecosystems, out-competing and eventually replacing native flora and fauna. The Lodgepole Pine (Pinus contorta) was introduced in the 1930s to Argentina, planted by immigrants for forestry. Since then, these Canadian pines have covered entire mountains, spreading past the native treeline into ecosystems that were never arboreal. While many studies have focused on the impact invasive species, such as the Lodgepole, have on local biodiversity, few have focused on the interactions that happen below the soil, between mycorrhizal communities. Understanding the change in mycorrhizal community structure induced by the invasion of these trees will grant us insight into the role and function that mycorrhizal communities play in terrestrial plant invasion and in impacting local biodiversity.
