Join us on your lunch break at Virtual 4TH SPACE over six days in July to hear from Concordia students and professors as they discuss their research on sustainability in general and the climate emergency in particular.
Originally scheduled as part of the now postponed cross-disciplinary conference Sustainability and the Climate Crisis, each of these six talks will highlight the varied research Concordians are currently undertaking to tackle the unfolding environmental emergency.
What does a community composed of native and invasive species look like in terms of structure and network? For many ecosystems in today’s world, biotic invasion means inevitable change/disruption to community composition, biological networks and ecosystem services. Common conservation strategies to deal with invasive species focus on eradication and restoration of invaded habitat as a way to revitalize the native community, however, for many biological invasions, removal of the invasive species is not feasible. For these communities, comprised of natives and invasive, our understanding of the ecological processes structuring species assembly, coexistence, and interactions is limited. Without understanding how invasive species shape and reorganize native communities we can’t design informed conservation strategies. My project aims to quantify native community response to invasion, by focusing on a specific invasion of Lodgepole Pine (Pinus contorta) into an alpine community in northern Patagonia, Argentina. Specifically, I ask the question; Are invading pines impacting the native alpine community? To answer this question, I measured compositional turnover in root-associated fungi, bacterial and plant communities between plots containing adult pines, juvenile pines (sapling) and no pines (control). Using a combination of variance partitioning, phylogenetic analysis and spatial mapping, I quantify the community-wide impact of invasive pines in this ecosystem. The results from this study can be used to inform policy makers seeking to conserve at-risk ecosystems from treeinvasion and give scientists a better understanding of the processes that shape and change biotic communities in invaded ecosystems. In ecosystems like this one, where removal of the invader is not feasible, the only path forward in conservation is through a thorough understanding of the processes responsible for the organization and stability of the novel community and the preservation of native species through informed management of the invasive.
