NordBorN is growing!

We are excited to welcome two new members to our network, Alexandra Barry and Maria Pavolotskaia!

Alexandra began her PhD studies at the University of Gothenburg in early September 2024. She has a BSc in Biology and Psychology from Virginia Commonwealth University and an MSc in Forest Resources from the University of Maine (both in the United States). Her current research focuses on how warming and other environmental changes in the Arctic tundra drive changes in plant community productivity through shifts in functional traits and community assemblages. She will use a combination of growth chamber experiments and field observations to tackle this question.

Maria will start her PhD at the University of Gothenburg in April, supervised by Anne Bjorkman. She has a MSc in Biology with a focus on Ecology and Conservation from the University of Gothenburg. During her PhD, she will study how pollinator communities in northernmost Sweden have changed over the past decades following warming and how these changes relate to the pollination services they provide to plants. Her research will explore shifts in bumblebee community composition, the plants they rely on for pollen collection, and how these changes influence patterns of plant reproduction.

Two postdoc positions in tundra data synthesis on Team Shrub at the University of British Columbia

Deadline: February 15, 2025

One postdoc will lead ITEX phenology syntheses including the integration of phenocam and below-ground data as a part of the Canada Excellence Research Chair Project on the global change ecology of northern ecosystems. The other postdoc will join the European Research Council Resilience project to look at spatial patterning in tundra ecosystems and how they might influence resilience in the face of global change.

You can read more about our research on our website: https://teamshrub.com/

There will be opportunities for fieldwork in the Canadian Arctic and potentially elsewhere as a part of both of these positions. The two postdocs will join the teams for these two projects based at the University of British Columbia and will have the opportunity to work with collaborators in North America and Europe and across the ITEX network. These postdocs will join current UBC postdoc Jeremy Borderieux who is leading new data syntheses with the ITEX plant composition data focusing on community assembly and spatial patterning as a part of the Resilience Project and the recruited Tundra Time postdoc at the University of Edinburgh (see below).

You can check out the positions and apply at the following links:

Postdoctoral Position: Plant phenology change over time across spatial scales

Postdoctoral Position: Spatial patterning and ecological resilience across the tundra biome

If you are interested in the Tundra Time postdoc at UEdinburgh, you can find that job advertised here.

NordBorN session at the EGU 2025!

We’d like to invite you to submit an abstract to our new session in Biogeosciences programme group: BG3.20 Borealization of tundra ecosystems at the EGU General Assembly 2025 (27 April–2 May 2025). Both on-site and online attendance is possible!

Arctic and alpine tundra ecosystems are changing fast in response to ongoing climate change and increased human pressures linked to land use changes. One observed phenomenon in response to these changes is the northward and upward shift in the distribution of temperate or boreal species from southerly latitudes or lower elevations, a process known as borealization. Examples of tundra borealization include the encroachment of woody species, the spread of non-native species, and changes in the composition of plant, animal and microbial communities. Borealization also alters the trophic and functional structure of ecosystems, changes landscape structure and impacts ecosystem processes such as the strength of carbon sink and sources.
This session aims to address the drivers, processes, and consequences of the borealization of tundra ecosystems, as well as its quantification from the perspectives of different disciplines, such as biogeography, remote sensing, (historical) ecology, and forest sciences. Multi-, inter- and transdisciplinary approaches are particularly welcome.
