🌳Climate-driven range shifts in alpine plants require recruitment beyond tree lines. For P. cembra, seed origin & maternal reproductive traits drive seedling establishment, potentially outweighing microclimate & maternal genetics @valgra.bsky.social @aaronkauffeldt.bsky.social 👉️ buff.ly/NyNPcJb

Excited to share my final PhD paper! We show how mother tree and seed position within an elevational gradient drive seedling recruitment in the Alps🌱⛰️ You can read it here: doi.org/10.1111/1365-2745.70303 @journalofecology.bsky.social @sgn.one @wslresearch.bsky.social @aaronkauffeldt.bsky.social

Our latest nutcracker paper is out! In a collaborative effort between @sgn.one and @vogelwarte.bsky.social we show how bird age can affect seed dispersal 🐥🌱 #ProcB @royalsocietypublishing.org Avian seed dispersal function is age dependent doi.org/10.1098/rspb... @matthiastschumi.bsky.social

Happy to share that the first paper of my PhD is out! We developed a trait-based framework 🌱🦜 to quantify how plant-frugivore interactions and animal movement shape plant functional connectivity—the dispersal of seeds between habitat patches. royalsocietypublishing.org/doi/10.1098/...

Check this out @valgra.bsky.social , @vsvanbergen.bsky.social & @steffopp.bsky.social Wondering whether this is indeed a nutcracker nest!?

So, this spring I am starting a pilot study searching for spotted nutcracker nests. The ultimate goal is to GPS-tag nestlings… apparently occupied nests are notoriously difficult to find (in case you have ever found one, please let me know!). Getting inspired at the natural history museum in Bern 😊

Raise a glass to Dr Rabeau, celebrating his viva today in Silwood bar. 🥂 Thanks to Rich Gill and Ilya Maclean for examining. 4 amazing Drs recently graduating from the lab in this pic, and 2 pre-Drs 🥰 @jyang19.bsky.social @ra-barber.bsky.social

Can we use tree-related microhabitats (TreMs)🌳 as indicators of #tropical #biodiversity? Our new study led by Giovanni Bianco shows that TreM diversity actually increases with temperature and decreases with human impact on Kilimanjaro 🇹🇿 Now published in Ecological Indicators: doi.org/10.1016/j.ec...
The figure shows the beauty and diversity of tree-related microhabitats recorded on Kilimanjaro, Tanzania.
