Ok, #botany and #dendrology people, could I ask you for verification of the claims made in this video, about the spiral path of juices traveling through a tree?

Honestly I love Andrew Millison #permaculture videos but this video... This video triggers my bullshit detector. There's nothing […]

This captivating image presents a serene forest scene, dominated by the majestic, silvery-white trunk of a birch tree, standing as a testament to nature's artistry. The tree, angled slightly, draws the eye upward, its pale bark a stark and luminous contrast against the deeper, muted greens of the surrounding woodland.
A striking feature is the dramatic vertical strip of rough, dark bark running down the center of the trunk, almost like a primordial scar or a painter's bold brushstroke, revealing the tree's ancient layers and history beneath the papery surface. This darker section is richly textured, a tapestry of fissures and crags, hinting at resilience and age but instead is a sign of new growth. Patches of vibrant moss or lichen, a verdant emerald, cling to this darker bark, adding a touch of vivid life and colour, their presence emphasising the damp, thriving environment of the forest.
The background recedes into a soft-focus haze of dappled light and shadow, where glimpses of other trees, their forms softened and indistinct, create a sense of depth and tranquility. Scattered fallen branches and dried leaves on the forest floor below add to the organic tapestry, suggesting the cyclical rhythm of nature. The overall impression is one of peaceful solitude, a quiet moment captured in the heart of a vibrant, living ecosystem.

Job offer:
PhD student in Palaeoclimatology/-ecology (f/m/d)
As part of the SNF-project Signatures of Global Late Glacial Climate Change in Tree-Ring Records (SiGnaL), co-led by the Dendrosciences group at WSL and the Laboratory of Ion Beam Physics (LIP) at ETH Zurich, you will, along with two other PhD students and technicians, contribute to understanding the nature and drivers of abrupt climate changes during the Late Glacial period (approximately 11’000-15’000 years ago). Your work will include the collection, measurement, and integration of fossil wood and tree-ring material from various global sites. Through a multi-proxy approach - combining radiocarbon dating, stable isotope ratios, and quantitative wood anatomy - you will help to date and synchronize records across regions and reconstruct regional to global climate dynamics. This will help refine our understanding of Late Glacial climate dynamics and contribute to improvements of the global radiocarbon calibration curve. 
 
You have a Master's degree in Environmental Sciences, Earth Sciences, or a related field, and preferably have already gained experience with radio-carbon and stable isotope measurements. You are comfortable analyzing and visualizing data in R or Python and are motivated to publish your results in scientific journals. You enjoy to work in the lab, with large datasets, and have an interest in interdisciplinary and international research. You like to work independently, structured and accurate. You are communicative and team-oriented and have excellent spoken and written English language skills as well as at least the knowledge of one Swiss national language.

PhD in Palaeoecology 100% (f/m/d)
As part of the Signatures of Global Late Glacial Climate Change in Tree-Ring Records (SiGnaL) project — co-led by the Dendrosciences group at WSL and the Laboratory of Ion Beam Physics (LIP) at ETH Zurich — you will contribute to understanding the nature and drivers of abrupt climate changes that occurred during the Late Glacial period, approximately 11 - 15 kyrs BP. Your work will focus on the collection, measurement, and integration of fossil wood and tree-ring material from various global sites. Through a multi-proxy approach — combining radiocarbon dating, stable isotope ratios, and quantitative wood anatomy — you will help to date and synchronize records across regions and reconstruct regional to global climate dynamics. This work will support the project's goal of improving our understanding of the Late Glacial climate system and enhancing the global radiocarbon calibration curve. You will be part of an enthusiastic and ambitious team that includes leading researchers in dendro-chronology, palaeoclimate research, and radiocarbon dating, along with two other PhD students and technicians. The position is based at WSL within the Dendrosciences group, a globally recognised centre for tree-ring science. Collaboration with international researchers from related institutions is also expected. Among the three PhD students involved in the project, you will have a special emphasis on wood anatomy and on the climatic interpretation of the tree-ring proxies.

Fun part about making camera GUIs is that you can make everything the color of mountain dew if you so wish. In the meantime, I finished the camera settings menu for FORGE. Now I can move onto programming in multi sample scanning.

Largest database on Mediterranean trees available through open access PRESS RELEASE - An international network of 30 scientists, coordinated by INRAE and the European Forest Institute (EFI) and involving Aix-Marseille Université, the University of Montpellier, the French National Forest Office and the French National Museum of Natural History, drew up an inventory of 496 species and 147 subspecies of trees in the Mediterranean region. These data, which are available through open access and include details on species extinction risk and genetic diversity, are vital for forest conservation and restoration. The findings were published in Current Forestry Reports.

Saplings are failing to grow, and older trees are only generally surviving for 125 years where they used to last for over 200 years. This will mean fewer trees to store carbon. #trees #dendrology #climatechange #forests #carbon

Job posting: Post-doc in wood formation 80-100% (f/m/d)
You will join a project co-led by the Dendrosciences group at WSL in Birmensdorf and the Remote Sensing group at EURAC in Bolzano (South Tyrol), focusing on the analysis and publication of wood formation data (microcoring and dendrometer) and tree-ring cell anatomical data collected from elevational monitoring transects in the Lötschental and Mazia valleys. These datasets are crucial for understanding the mechanisms behind intra-annual tree-ring responses to climate change. The project aims to quantify water- and carbon-related growth responses along elevation gradients and across contrasting climatic years. Your main task will be to analyse the data and prepare a scientific publication detailing these climate-related responses.
You have a PhD degree in Environmental Science, and preferably have proven expertise in xylogenesis, dendrometer and cell anatomical data analysis with R, and proven ability to publish in scientific journals. You have a flair for handling big data and for programming. You can efficiently expand and acquire knowledge in topics relevant to the project. You have a proficient command of spoken English, can work in a structured and independent manner, possess a high level of team spirit, and have excellent communication skills. You will be part of an enthusiastic and ambitious team that includes leading researchers in dendrochronology and in environmental data management. The position is based at WSL within the Dendrosciences group, a globally recognised centre for tree-ring science. Collaboration with international researchers from related institutions is also expected.
