“A truly global monitoring effort should promote fair and equitable collaborations, transferring funding to and empowering scientists from less wealthy regions.” Proud to see this published! 🌳Many thanks to @corneliussenf.bsky.social, Adriane Esquivel-Muelbert, and Thomas Pugh for leading the paper!

Good news for a change: Background mortality in unmanaged forests of Europe has not increased over past decades. Great work from the European Forest Reserve Initiative EuFoRIa, out in @journalofecology.bsky.social doi.org/10.1111/1365...

‼️🪶The future reference for basic and applied research on #invasivespecies. 🏝️It was an honour and a pleasure to contribute to this important global study from the perspective of the tropical #Pacific #Islands. Thank you for taking me on board!

Where modern multi-causal #research into #forest #decline began...

Dieter´s interdisciplinary research into the causes of large-scale #forest #dieback in forests on the islands of #Hawai´i throughout the 1970s and 80s had a global impact and can be seen as exemplary for modern multi-causal forest #decline #research. Context: muse.jhu.edu/pub/5/articl...

Prof. Mueller-Dombois has been studying #forest #dieback in the Hawaiian #Islands since the late 1960s. This aerial photograph was taken during a reconnaisance flight over the dieback area in #Alaka´i Swamp, Kaua´i, in March 1972. Photo by D. M.-D.. Context: www.google.de/books/editio...
March 1972: Hawai´i, Island of Kaua´i, Alaka´i Swamp area. Aerial photograph of forest dieback. Dying and dead Metrosideros trees stand out in grey against the few remaining healthy, green trees. Note on slide: `Terminal dieback, Alaka´i, March 1972`. Photo by Dieter Mueller-Dombois. The Alakaʻi Swamp (Alakaʻi Wilderness Preserve) is a montane rainforest on the island of Kaua´i in Hawai´i, located on a plateau near Mount Waiʻaleʻale, one of the wettest places on Earth. Although it is called a swamp, it is actually a rainforest.

Our latest work with @colauttilab.bsky.social is out today!
Always great to work with Rob, one of the best evolutionary biologists out there. We hope this work sparks some important conversations on allelopathy and reproducibility in ecological research.

An important paper considering time scales of turnover and the coupling with the climate.
P.S. The detected breakpoint at the time scale of 1000 years is what Shaun Lovejoy called macroweather-climate transition (in the Holocene epoch).

Fieldwork in #forests and incredibly beautiful #meadows of southern #Slovenia as part of the EU Horizon project @zoe-eu.bsky.social . Fantastic support by Nataša Knap & Team (Institute of Microbiology and Immunology, University of Ljubljana) and Tea Knapič (Slovenian Museum of Natural History)!

It is a great honour to become the coordinator of the #IUFRO Task Force 57 ‘Legacy Forest Data and Related Resources’ and to work with my deputy coordinator Sheila Ward and numerous colleagues from many countries around the world to rescue, curate and disseminate legacy #forest data.

IUFRO Headquarters in Vienna is happy to currently host its Enlarged Board for its 1st meeting in the new term of office.

70+ forest scientists from around the world participate either in person or virtually to discuss matters related to forest research and forest science.

We had inspiring days of intensive fieldwork in #forests and #meadows in the region north of #Bratislava as part of the EU Horizon project @zoe-eu.bsky.social. Many thanks to Boris Klempa and the Biomedical Research Centre of the Slovak Academy of Sciences (BMC SAS) for their fantastic support!

This big pantropical analysis led by @kofitim.bsky.social integrates tree diversity, ecology and biogeography. Combining long-term records from ForestPlots and ForestGEO, reveals that faster life-history strategies tend to drive bigger ranges and more diversity.
