🚨 PhD alert. PhD opportunity studying how nutrient availability impacts the ability of ecosystems to absorb more CO2 as CO2 levels rise. With Catriona MacDonald and Ben Smith at Western Sydney University and myself here @sheffieldpps.bsky.social Sheffield www.findaphd.com/phds/project...

Excited to share that our new paper “Summer 2024 in northern Fennoscandia was very likely the warmest in 2000 years” has been published in npj Climate and Atmospheric Science! See the open-access paper from doi.org/10.1038/s416... Short thread 👇

🌸Plant diversity dynamics over space and time in a warming Arctic 🌸 Our new study @nature.com analysed plant diversity change in >2000 tundra plots over 4 decades. We found that plants changed unevenly, mostly driven by warming and biotic interactions. www.nature.com/articles/s41... 🧵 (1/7) 🌐🧪🌱🌍

Interesting paper: Increases in Arctic Extreme Climatic Events Are Linked to Negative Fitness Effects on the Local Biota. doi.org/10.1111/gcb....

Interesting paper: Tundra Plant Canopies Gradually Close Over Three Decades While Cryptogams Persist doi.org/10.1111/gcb.... As the authors point out, "These results call into question the dominant dogma that cryptogams will decline with increases in vascular plant abundance" 🤯

New paper: The changing face of the Arctic: four decades of greening and implications for tundra ecosystems www.frontiersin.org/journals/env...

Interesting paper: Wildfires offset the increasing but spatially heterogeneous Arctic–boreal CO2 uptake www.nature.com/articles/s41...

An important Starter Pack that could use your support in following, reposting, or by tagging scientists, locals, key stakeholders, and Arctic-centric entities that deserve to be represented. Thank you. go.bsky.app/KxURBR1

We are looking for a grant-funded doctoral resarcher on a project focusing on how tree and shrub expansion into the tundra impact biodiversity and carbon balance @Department of Geosciences and Geography @helsinkiuni.bsky.social! DM me if you are interested, and please share!

Our review paper “Browning events in Arctic ecosystems: diverse causes with common consequences” is out in @plosclimate.org journals.plos.org/climate/arti... @sheffieldpps.bsky.social, @robertgbjork.bsky.social, @scootjd.bsky.social, @thissideofthearctic.org, @arctic-carolina.bsky.social

A new PLOS Climate Review article by @garethphoenix.bsky.social and colleagues brings together understanding of browning events in Arctic ecosystems to compare their impacts and rates of recovery, and likely future changes in frequency and distribution journals.plos.org/climate/arti...

Interesting paper: Increasing certainty in projected local extreme precipitation change. Some regions are going to have big increases in annual maximum daily precipitation, and this is now known with greater certainty. www.nature.com/articles/s41...

Interesting paper: Substantial and overlooked greenhouse gas emissions from deep Arctic lake sediment. Carbon release from deep sediment permafrost thaw (20m in this study) may be much more important for changing climate than thought. www.nature.com/articles/s41...

"Waning snowfields have transformed into hotspots of greening within the alpine zone" www.nature.com/articles/s41...

I like this: Regional fire–greening positive feedback loops in Alaskan Arctic tundra Fire promotes arctic greening by facilitating establishment and growth of larger stature deciduous shrubs and other species. And the more severe fires do this more. www.nature.com/articles/s41...

Enhanced warming of European mountain permafrost in the early 21st century www.nature.com/articles/s41...

Interesting: Diminishing warming effects on plant phenology over time. This meta-analysis shows that the rate of change of plant phenology in response to warming declines over time. nph.onlinelibrary.wiley.com/doi/10.1111/...

Quote: "One of the beautiful things about science is that it allows us to bumble along, getting it wrong time after time, and feel perfectly fine as long as we learn something each time". I quite like that 😊

Misclassifying Oroarctic areas has led to significant confusion. Risto Virtanen's old paper deserve more attention for clarifying this. The European tundra falls into 3 distinct categories: Arctic, Oroarctic, and Alpine #ClimateScience #Oroarctic #ArcticTundra onlinelibrary.wiley.com/doi/full/10....

Icing-related injuries in polar bears (Ursus maritimus) at high latitudes. In (very) short: new climate regime brings with it new injuries not reported before. esajournals.onlinelibrary.wiley.com/doi/10.1002/...

Wow 😱: The western arctic caribou herd has largely abandoned its southern ranges as winter survival has worsened there. In: Evidence for an Adaptive, Large-Scale Range Shift in a Long-Distance Terrestrial Migrant. onlinelibrary.wiley.com/doi/10.1111/...

Take a look at this excellent array of PhD projects in plant and soil science that are nowopen for applications! Please share with potential students 🤩

Interesting: Decline in Coupling Between Vegetation Photosynthesis and Greening in Northern Ecosystems During the Photosynthesis-Up Period (PUP). In (very) short: More photosynthesis in the PUP, but its links to greening (a major driver) is getting weaker. onlinelibrary.wiley.com/doi/10.1111/...

PhD opportunity!! ➡️Heathland Flammability Responses to Environmental Change 🌿🔥 centa.ac.uk/studentship/... Work with a great team of researchers at University of Birmingham, University of Exeter, Forestry England & Met Office!

Interesting: Reindeer grazing reduces climate-driven vegetation changes and shifts trophic interactions in tundra. in @oikosjournal.bsky.social nsojournals.onlinelibrary.wiley.com/doi/10.1111/...

Nice paper: Arctic soil carbon trajectories shaped by plant–microbe interactions. In short - C losses by stimulated microbial decomposition with nutrient addition on tundra later offset by greater plant growth. www.nature.com/articles/s41...

"Unintended consequences of planting native and non-native trees in treeless ecosystems to mitigate climate change". In short- its not always a good idea. A good mini-review in @journalofecology.bsky.social besjournals.onlinelibrary.wiley.com/doi/10.1111/...

Winter may soon be over - first lot of photographs are coming in for 2024 from the Forsinard Flows site in northern Scotland as part of the Tracking the Colour of Peatlands Project

Come work with us! We're hiring two postdoc research fellows working broadly on nature-based climate solutions, including mitigation and natural sinks. If you'd like to chat about these, please get in touch. tinyurl.com/mt8stvmr @sheffieldpps.bsky.social @sheffielduni.bsky.social
