Preparing the upcoming experiment and measuring pre-treatment lead gas exchange is a totally different experience when you are visited by hummingbirds and you are having a monarch butterfly caterpillar to pet in the greenhouse :) #plantecophys #plantscience #ucberkeley #ecology

Just planted Sequoia sempervirens/Coastal Redwoods, the first of 12 tree species I will be studying during my fellowship here in California 🌲🌳🔬

🌳PhD Opportunity in plant ecophysiology🌡️ Join EPFL (Switzerland) for fully-funded 4yr PhD on tree responses to air drought and heat. Climate chamber + long-term experiments to uncover physiological thresholds under climate change. www.epfl.ch/labs/perl/pe...

In our recent study, we demonstrate how high temperatures alter leaf-level C dynamics, resulting in a significant shift towards sugars as the primary C reserve, and concurrent shifts in 2H and 18O composition @lehmannlab.bsky.social @arthurobuntspecht.bsky.social @wslresearch.bsky.social

Featured on the cover of @globalchangebio.bsky.social is a thermal image of Elaeocarpus Grandis taken at @jcuofficial.bsky.social Daintree Rainforest Observatory. In this species we find that populations originating from warmer climates have narrower leaves with higher rates of water loss.

Nice diversity among my different Quercus pubescens genotypes from 1) Pfynwald, Switzerland; 2) Crete, Greece; 3) Barcelona, Spain. 4) is Quercus infectoria ssp veneris from Polis, Cyprus (the massive ones next to the pub) which are growing unexpected fast.

After a month of more rain, trees and shrubs are starting to have crispy leaves again. Lets see how far they will dry out during the next few days, and whether there will be enough rain comming next week to make them recover. I doubt that there is a future for most native tree species

Hiking on the Azores is often hiking through novel ecosystems with probably over 90% introduced plant species. Likely the future of many regions until the end of this century due to the expected strong missmatch between the climatic conditions and the bioclimatic envelope of the native species

First signes of early #drought are visible on trees and shrubs in a forest close to my hometown. While the current (~25mm) rain helped for sure, this water will already soon be evapotranspirated based on weather projections. Lets see how severe the drought will hit during the comming months

Only few people know that we have (introduced) wild cacti in Switzerland. Today, I was finally able to visit Opuntia phaeacantha and O. mesacantha in Sion, Valais. I wonder if the native lizarsds are also eating and disperse them as the lizards on the Canary Islands do

Our latest study (submitted to JXB) is now available as a preprint. We emphasise the importance of directly measuring the CO2 flux of whole plants.🧵

Contrary to popular belief, what is important in science is as much its spirit as its product: it is as much the openmindedness, the primacy of criticism, the submission to the unforeseen, however upsetting, as the result, however new that may be. – Francois Jacob www.nature.com/articles/s41...

Want More Bees in Your City? Mix Up Your Flowers A new study finds that cities can support more wild bee species by planting a greater variety of flower shapes—not just more flowers. botany.one/2025/05/want... Read the original research at doi.org/10.1002/eap....

I recently read & reviewed @olufemiotaiwo.bsky.social's book, 'Reconsidering Reparations'. The connections he draws b/t slavery, colonialism, capitalism, and climate justice are conversations we don't have enough of in ecological discourse. I recommend reading it. open.substack.com/pub/benlockw...

We have 3 players in a grassland: plants, microbes and soils. Who is winning on the fight for N under drought and warming conditions? Should we adapt our management strategies? Come to my #EGU25 talk on Wed to find out! BG3.5 @reclean.bsky.social meetingorganizer.copernicus.org/EGU25/EGU25-...

🌳Urban trees keep cooling - even during record-breaking heatwaves! We show that trees maintained high transpiration, defying model predictions. Tree cooling during heat may be underestimated 🌡️💦 Great study led by Christoph Bachofen @wslresearch.bsky.social doi.org/10.1016/j.uf...

Great news that the 1st Guam Kingfishers released into the wild for 40 yrs are nesting. This bird may become the poster-child of assisted colonisation (and possible future speciation) as their new home is >3500 miles from Guam – London-to-New-York kind of distance. Background in this older link:

Happy to share the preprint of our latest study on 2H and 18O fractionation, showing the close connection between leaf sugar d2H and the leaf level carbon dynamics. This was part of the 4th chapter of my PhD thesis, however it is now much more improved compared to the thesis version 🥂

I really love to collect seeds of rare and/or species that are often not included in studies, so I can grow them by myself and use them in my future experiments #plantscience #botany #plantphysiology #oaks #quercus

Look at these amazing Quercus infectoria subsp. veneris with huge acorns, looking similar to the ones of ithaburensis. Closely related to Quercus pubescens and the other roburoids. Likely having important genes for introgressive adaptation of robur and petreae in Central and Western Europe

Bad news for Myrtaceae in Europe: we detected the highly damaging myrtle rust on dutch indoor bonsai which were sold in Obi, Switzerland. I have contacted the dutch authorities in charge, responsible for the phytosanitary certificates, however they replied in an incredible disapointing way (1/2).

I finally managed to find Quercus alnifolia, the endemic oak species of Cyprus. Amazing how similar it is to Quercus chrysolepis from California - oaks are the master of convergent evolution and evolve the same traits over and over again! #botany #quercus #quercisalnifolia #plantscience

Check your baseline! It’s reasonable to assume that hippos in Colombia is a problem but studies don’t find the expected eco-catastrophe (doi: 10.1002/ECY.2991) Is it due to previous degradation from agriculture or a yet-small population? www.facebook.com/100001523860...

Birds are excellent seed dispersers. Tip: To accelerate natural regeneration in an open landscape, "plant" some large dead branches in the ground. When birds fly over, they may stop for a rest on the branches, hopefully donating a deposit of seeds and fertilizer to your nat regen project!
