Hello there, let me introduce you to Salix polaris shrub from Svalbard. My entire Arctic dendrochronology adventure has started from this little one shrub sampled in 2009 in central Spitsbergen. The dwarf polar willow from the tundra.

There are winners and losers on the tundra. In our new study we show a close link between sea ice decline and tundra shrub growth in the Arctic. A divergent growth across the Arctic hidden in a tiny shrub rings: pnas.org/content/early/…

Here's how tiny growth rings revealed the secret link between sea ice loss and tundra "greening" and "browning." arctictoday.com/how-tiny-growt… by Yereth Rosen

Changes in moisture availability due to sea ice loss may constrain Arctic shrub growth responses to increasing temperatures and should be considered in climate change feedback projections. In PNAS: ow.ly/HENc50CLxKD

Really interesting study. And another ecological example of "not so fast my friend". Warming increases shrubs in the arctic, right? Except if warming leads to drying - then shrubs decrease Divergence of Arctic shrub growth associated with sea ice decline pnas.org/content/117/52…

As Arctic sea ice steadily disappears and temperatures rise across the region, scientists have found that 37 percent of tundra plants are experiencing stunted growth and browning. e360.yale.edu/digest/study-o…

Do You feel blue? Rings can do that too! Blue rings can be found in trees, including Scots pine roots! Check out our new study published in #Dendrochronologia led by Pawel Matulewski UAM Poznań doi.org/10.1016/j.dend…

Happy to share our Betula nana study from arctic Alaska Toolik Field Station. June temperature rules the shrub growth and you can check how specific shrub part (i.e., root, stem or branch) is sensitive to climate. Thank You @FulbrightPoland and INTERACT. doi.org/10.1007/s10021…

New blog post by some lovely guest researchers (Agata Buchwal @PMatulewski Ylva Sjöberg) that visited #nibio #Svanhovd this summer to collect samples from #Juniperus. #climate #research NIBIO Norwegian Institute of Bioeconomy Research INTERACT lnkd.in/dtZTtQnx

Karttatarkastelu on tärkeää ennen ensimmäistä kenttätyöskentelypäivää uudessa kohteessa. Agata Buchwal ja Pawel Matulewski UAM Poznań'sta sekä Ylva Sjöberg University of Copenhagen'sta vieraanamme seuraavan viikon tekemässä havupuiden lustotutkimusta.

#Kataja'n kasvumuoto riippuu pitkälti kasvupaikasta. Elokuun alussa asemalla vierailleet @PMatulewski Agata Buchwal ja Ylva Sjöberg löydöt Värriöstä havainnollistavat tämän. #dendroecology #dendroclimatology #dendrogeomorphology #treering

Agata, Ylva ja Pawel tekivät myös muutamia mäntykairauksia meillä vieraillessaan. Puiden kulloisetkin kasvuolosuhteet voi nähdä kairasydämien eri paksuisina lustoina. #dendrokronologia #dendrologia #dendroecology #dendroclimatology #dendrogeomorphology #treering #woodanatomy
