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.🧵

The carbon (C) balance of plants is the sum of all source and sink processes. However, due to methodological limitations, most studies focus predominantly on measurements of leaf-level assimilation an...

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...

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:
