樹幹流（じゅかんりゅう） stemflow 🗓️ 4月30日(木) 13:00 📍 1 号館 31 番教室（地下） お仕事終了！明日の学生実習では、アシスタント役のまっつーさんも教壇に立って、樹幹流計測の手法について解説するみたいですよ！ こんちゃんも大学に授業参観に来てね♪ 一番後ろでもファンサするから！！！

Tree Soap I found a large mound of foam at the base of my cherry tree, the trunk is covered in moss at the bottom and my immediate thought was hedgehog spittle. But I was wrong. Never having seen this before I did a search online and found this article. It’s fascinating. Bubbles piling up at the base of trees, especially after heavy rains, is somewhat commonplace.  During dry periods, there is an accumulation of salts, plant chemicals and other particulates from the air that coat the bark surface.  Soap is essentially a collection of salts and acids. Think of it like you have all ingredients ready and waiting for making a crude, albeit very simple ‘au natural’ soap solution.  Everything is ready and waiting for the final ingredient—rainwater.   As rainwater trickles down the tree stem or trunk (called stemflow), it collects deposited dust particles (i.e. salts) and plant residues (i.e. acids) that have accumulated on the bark surfaces.  Bubbles are formed through the process of “stemflow mixing”.  As this dissolved, simple soap solution flows down the trunk, it encounters barriers and bumps, like bark plates, furrows, and ridges.  The solution is then tumbled, mixed and aerified, during its downward flow to the ground, generating the bubbles or soapsuds, which collect at the tree base.  Occasionally, a light coating of foam may even be visible higher up on the tree trunk.  Stemflow mixing has no known deleterious effect on tree health.   Tree suds can happen in all types of trees and has been observed occurring in all continents where trees grow.  There is absolutely no need for worry, if foam forms on your trees during or after heavy rains.  In fact, it is an awesome natural phenomenon, so just sit back, relax, enjoy the rain and the bubbles!

おはようございます𓂃 𓈒𓏸 よく見ると幹の片面だけ濡れっぱなしです。付着した雨が伝った跡だと考えられます。樹幹流 stemflow を測るために測器はこっち側に設置して... とか考えます🫧 それと、よくうねる広葉樹の樹幹流は経路が複雑なので測るのは骨が折れます😓

betul Tp sebenarnya yg lbh dahsyat dr hutan bkn akarnya. Tpi, kanopi hutannya. Kanopi yg lebat mnybbkan air hujan yg turun harus melewati kanopi dulu (intersepsi), lalu baru turun ke tanah. Baik throughfall ataupun stemflow. Shga, hujan yg turun gak lgsg menghantam tanah

Let's just get outta' here and take a walk 🚶‍♀️ This is called stemflow.. The rainwater mixes with dust, pollen, dirt, oils, & gunk that has accumulated on the bark- when the water flows down the tree it creates a crude soap that in turn makes bubbles.

In Reviews of Geophysics, scientists take the first step in exploring and defining the hydrodynamics of stemflow, the flow of water along the surface of a plant’s stem.

久々のまとまった雨のせいか、樹の根元に樹幹流でできた泡が立っていました。 樹に付着した細かい粒子や樹から分泌された物質が雨水に溶けることで泡立つようになります。 #高尾山さる園・野草園 #樹幹流 #stemflow #mttakao #高尾山

Our latest paper uses LiDAR-based forest structure to quantify stemflow!

I am happy to share new study published in Forests. Many congratulations to Wenfeng Jiang and Kai Yue from Fujian Normal University. #stemflow #throughfall #canopy #forests #fluxes #nutrients #UMT #IBTPL mdpi.com/3135094 #mdpiforests via @Forests_MDPI

It’s a natural phenomenon known as Stemflow Mixing, caused by rainwater mixing with chemicals in the bark. 😊

i recently launched @stemflow a nonprofit organization to get more kids involved in STEM STEMflow is an online learning platform that pays students and instructors our site is open for instructors to create courses for our students so come check us out! stemflow.net

Thank you @ankehildebrand1 for visiting the #RedellaPietra #experimental #catchment last week and give us her advice on how to best capture variability in #ecohydrological #processes. danielepenna.wixsite.com/red… @DagriUnifi #hydrology #isotopes #trees #stemflow #water

Very insightful Sunday afternoon with @Prof_Van_Stan and Christian Wirth at the Arboretum Großpösna!! Cool discussion about hydrological plant traits, rain partitioning, stemflow, current political issues in the world! @Prof_Van_Stan ! @idiv @Rsc4Earth @agwirthweigelt

Delighted to share a new paper from #wundergrad Aryan Puri - melding experimental and theoretical techniques to reveal physics of stemflow / pourpoint formation from intercepted rainfall. onlinelibrary.wiley.com/doi/… #interception #research #hydrology @UWAresearch @CWSS_UWA

Today with #students in the Re della Pietra #experimental #catchment under the #rain... so stimulating, nice and educative to see #hydrological and #ecohydrological #processes live! Just as I wrote here: onlinelibrary.wiley.com/doi/… #trees #stemflow #overland #flow #water #academics

Koalas get most of their water from eucalyptus leaves they eat. They rarely drink water in the wild. They also get water by "tree-licking" during rainfall. Scientists call this process "stemflow". 🐨🐨🐨

Stemflow is just gorgeous. It also functions to bring nutrients from the tree canopy (like sodium) back to the forest floor!
