@zalf.bsky.social and @marenecohydro.bsky.social a lab's strength is its shared toolkit - and we mean more than hardware.

Last week I had a very nice exchange with Amelie Stieg and Britta Horstmann from Leibniz central office to discuss the Leibniz SAW collaborative excellence program and using in-situ stable isotopes for detecting dynamic feedbacks in C and water cycling.

🌾💧 SPECIAL ISSUE RESEARCH 🌾💧

Zhen et al. discovered that the density of small openings—called stomata—located on barley stems is associated with whole-canopy water use much more than those located on the leaf blades 🌿🌾💧

🔗 doi.org/10.1093/jxb/...

#PlantScience 🧪
Fig. 2.Relationship between stomatal density of the abaxial side of the leaf sheath (SD SheathAb) and water use traits. Linear regression of whole-plant transpiration rate (TR, A) and canopy conductance (Gs, B) against SD SheathAb. Different colors refer to groups of genotypes belonging to one of the five families of the AB-NAM population that were phenotyped, with squares indicating the parents of the five nested association mapping (NAM) families. The BLUP values of each genotype were used in the regression analysis. ***Significant at P<0.001. The solid blue line indicates the regression line, and the shaded gray area indicates the 95% confidence intervals.

So the bad news is that impacts of_extreme_droughts worsened dramatically over time, but the good news is that these systems were not progressively impaired by_moderate_droughts. And, for us, it's good news that we have published these findings! Stay tuned; many more DN manuscripts are in progress.
Yellow-flowering goldenrod plants poke through the tops of rainout shelters for the International Drought Experiment (IDE) in a field at the Purdue Wildlife Area near West Lafayette, Indiana, USA. This was one of 74 IDE sites used in the study.

...while the effects of droughts that were extreme (i.e., 1 in 100 year events) compounded over time, perennial grasslands and shrublands were more resilient to less extreme droughts. That is, drought-related reductions in plant growth did not magnify over more years of moderate drought. (2/3)
Two panel graph showing the productivity response of ecosystems to moderate drought remained constant from 1-4 years of drought, while the productivity progressively decreased from the first to the fourth year of drought in systems consistently exposed to extreme drought.

Congratulations to, and very proud of, Matteo Verdone who successfully (with laude!) #defended his #PhD today on #ecohydrological dynamics in #forested #catchments at @UNI_FIRENZE. Thanks a lot to the other supervisors @iljavan meerveld and @ecohydrologylab.bsky.social for their fundamental support!

Zitat von Dr. Nicole Wellbrock vom Institut für Waldökologie über die Bedeutung des Tiefenspeichers im Wald für Trinkwasser und die Herausforderung der Trockenheit, mit Porträt der Frau mit Brille und kurzem Haar. Text: „Wir sorgen uns im Wald vor allem um den Tiefenspeicher, der sich nur langsam wieder auffüllt. Da unter Wald oft Trinkwasser gewonnen wird, ist die Trockenheit eine besondere Herausforderung.“ Dr. Nicole Wellbrock vom Institut für Waldökologie Porträt von Dr. Christopher Poeplau mit Zitat über verdichtete Ackerböden und Wassereindringung, Hintergrund zeigt gepflügten Ackerboden und Wald. Text: „50 Prozent aller Ackerböden sind stark verdichtet. Selbst wenn es genug regnet, kann das Wasser gar nicht oder nicht tief genug in die Böden eindringen.“ Dr. Christopher Poeplau vom Institut für Agrarklimaschutz
