Technical Note: Spectral correction for cavity ringdown isotope analysis of plant and soil waters Abstract. The development of laser spectroscopic analysers has revolutionized isotope hydrology, dramatically increasing accessibility and reducing the cost of sample analysis. Despite their substanti...

35th European Dendroecological Fieldweek We are pleased to announce the 35th European Dendroecological Fieldweek, taking place from August 29 to September 5. This event will be held in the town of Son (Spain) at the heart of the Catalan Pyre...

I am very happy to announce that the Dendrolabs of @wslresearch.bsky.social and @biologiaub.bsky.social will be co-organizing the 35th European Dendroecological Fieldweek in the Pyrenees! It's the perfect opportunity to learn about dendrochronology and have fun in a beautiful landscape!

The Isotopic Biases of Plant Stems Bulk Water From Different Water Sources by Cryogenic Vacuum Distillation Demonstrated Through Rehydration Experiments Hydrogen and oxygen isotope offsets (δ2H and δ18O) of cryogenically extracted plant stem bulk water and reference rehydration water for 12 plant species: (a) hydrogen isotope offsets and (b) oxygen i...

Here's a more recent one in the same topic, very informative!

Evidence for variations in cryogenic extraction deuterium biases of plant xylem water across foundational northeastern US trees Through a series of tree core rehydration experiments, we demonstrated that xylem water 2H cryogenic vacuum extraction (CVE) biases varied significantly with plant water status and species identity. ...

Hi Philipp, if seeds are from near the city, they could also be Q. cerrioides, an hybrid of pubescens with Q. faginea. They tend to have the lobes more pronounced and saw-like
