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 🐥🌱

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.

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.
