DendroLund

Fieldwork in Söderåsen National Park.
Together with colleagues, park managers, and the County Administrative Board, I am involved in a nature conservation and palaeoecological project aimed at reconstructing the long-term history of the beech forest in the area over the past millennia.

The work includes coring of lake-bottom sediments from Odensjön at a depth of around 20 m. Due to the weight of the equipment, sampling is carried out from a drilling rig with the corer suspended on steel wire.

The project also combines pollen and macrofossil analyses of the sediments with tree-ring sampling of beech trees in the surrounding forest, providing insights into patterns of tree establishment and growth over time.

I’m happy to share that I’ve taken on the role of Editor-in-Chief of Dendrochronologia 🌳

It’s a real pleasure to take on this role together with Cristina Nabais. We’re looking forward to working with the journal’s associate editors, reviewers, and authors. Dendrochronologia has long been a key forum for tree-ring research, from climate and ecology to archaeology and wood anatomy, and we’re excited to help take the journal forward.

I’m looking forward to working with the international tree-ring community and supporting high-quality and innovative research in the years ahead.

Check out our new article, hot off the press! We investigated how climate change affects tree growth in boreal forests and show that the response is likely mediated by local climate conditions and species-specific traits. Using tree-ring width data from Norway spruce (Picea abies) and Scots pine (Pinus sylvestris) in the Swedish National Forest Inventory, we assessed species-specific growth–climate relationships along gradients of mean annual temperature and soil moisture.

Unpacking climate effects on boreal tree growth: an analysis of tree-ring widths across temperature and soil moisture gradients Abstract. The effect of climate change on tree growth in boreal forests is likely mediated by local climate conditions and species-specific responses that vary according to differences in traits. Here, we assess species-specific tree growth responses to climate along gradients of mean annual tempera...

New publication on how we can use carbon and oxygen isotopes from peatland pines to study hydroclimatic changes. The study is a great collaboration between the projects TURBERAS (University of Geneva) and MOSS (Lund University). Enjoy! 🌳💍🔬

Peatland trees record strong and temporally stable hydroclimate information in tree-ring δ13C and δ18O Abstract. Peatland trees are valuable archives of paleoclimatic information; however, gaps persist in understanding the relationships between tree growth, peatland hydrology, and hydroclimate variables. While previous research in peatlands has mainly focused on tree-ring widths (TRW), yielding incon...

The Laboratory for Wood Anatomy and Dendrochronology, Lund university, recently received new samples from the underwater investigations at Bulverket on Gotland, carried out by Peter d’Agnan and his team. Analyses are now underway, and we’re hoping for fascinating results that will provide fresh insights into this remarkable historical site. ArchLab

New paper on stand-age effects on biodiversity in Swedish oak forests. Enjoy 🌳

Low cross-taxon congruence and weak stand-age effects on biodiversity in Swedish oak forests - Biodiversity and Conservation Assessing cross-taxon congruence is vital for effective forest conservation, because different taxonomic groups may respond inconsistently to key habitat variables such as stand age. We examined six taxonomic groups—insects, arachnids, springtails, epiphytic lichens, bryophytes, and vascular plant...

Since the 1970s, work with subfossil oak from peatlands, archaeological excavations, and submerged landscapes in Denmark and southern Sweden has been ongoing. In 2010, I sampled my first subfossil oaks, and since then, I have been trying to compile the extensive material that exists. The goal was to create an 8,000-year-long continuous chronology. There are still some gaps, but we have made significant progress, and perhaps in another 15 years, those gaps will be filled. In any case, I now look forward to continuing research on the material to conduct paleoclimatological studies. Enjoy our latest open-access paper!

Visiting SLU (swedish university of agricultural sciences) to discuss carbon storage in urban trees. 🌳💍🌇

In the brain of a dendrochronologist during rehabilitation. Can't the velcro straps that fix the fingers hold my increment corers together during movement in the field? Looks neat anyway… 🌳💍
