Who is at the Gordon Conference on #Photosynthesis? If you are, make sure to visit JII's Moges Retta at his poster on electron transport.

Also a special shoutout to Mauricio Tejera-Nueves, who is even celebrating his birthday while presenting at the #SEB2025. If you see him, congratulate him! 😜🍻

It's unusually quiet at the institute this week: everybody seems to be in #Antwerp for the SEB conference! #Photosynthesis is well-represented with sessions by Dezra Strand (photo), Juanita Solin and Tom Theeuwen. #SEB2025 @sebiology.bsky.social

Thanks to the technical expertise of Ludovico and others at JII – Atsuko Kanazawa – and Jingcheng Huang, Robert Zegarac and team at partner organization @michiganstateu.bsky.social, we can quickly iterate and improve on the sensors and test them out. We’re looking forward to seeing the results!

Ludovico placed two sensors: one in the full sun with a solar panel, and one in a shady area on batteries. Over the coming months, he will check how they are doing and add more sensors as they become available.

“This is a great location for a test run with these sensors,” Ludovico says, “because it’s actually quite desert-like. It can get over 50 °C here on some days! A perfect place to see if plants react to high temperatures similar to those in Australia, where we want to set up bigger experiments.”

JII Research fellow Ludovico Caracciolo has been one of the people working on the ‘Ambit’ sensor, and here we see him placing one of the sensors in an area within the Hoge Veluwe that is known to be very dry and hot. #hogeveluwe

To really understand #photosynthesis, we need to capture those changes by measuring plants continuously. That’s why we’re working on a #sensor that can remain in the field. And this week we’ve started the first tests during hot weather, at National Park De Hoge Veluwe in the Netherlands.

The findings offer a first-of-its-kind, high-resolution look at how the Amazon canopy navigates seasonal extremes.

With him was the MultispeQ device, an open science instrument by JII’s scientific director David Kramer, that he used to measure how leaves in natural settings balance incoming light with their ability to photosynthesize or dissipate excess energy.

New paper on some spectacular research by @leoziccardi.bsky.social @starkfloresta.bsky.social , JII's scientific director Dave Kramer and others.
