Fires beyond fire-prone ecosystems
Or how fire can erode beech forests
https://onlinelibrary.wiley.com/doi/full/10.1111/gcb.71036

Global warming weakens the flammability barrier & enables fire to spread beyond fire-prone ecosystems, into fire-sensitive species

Sculptured
Fallen leaves of the Nothofagus gunnii nestle in a cradle of wood in the Mount Field national park. Their vibrant copper hues are thanks to seasonal senescence: not just the process of ageing, but of chlorophyll degradation and nutrient resorption by the tree in the lead-up to winter’s arrival.

Alpine Overture
The ‘turning of the fagus’ in Tasmania’s alpine regions is one of the most spectacular seasonal events to witness. The leaves of the deciduous beech or ‘fagus’ (Nothofagus gunnii) transform from green to a vibrant tapestry of red, yellow and orange in autumnal transition.

200 isn't really a #milestone (wouldn't that be 1000?), but not a bad number of reads for a #preprint of a paper deemed not fit for publication.

Currently processing the data to please the editor (more P.R.Chinese samples), nothing unexpected came up but all analyses will have to be updated and streamlined.
So enjoy the original, the final product will have more tips but not more content 😅

Article on the spread of beech leaf disease (BLD) in the United States. It's caused by Litylenchus crenatae, a nematode from Asia. #beech #tree #trees #nematode #biology #disease #arborists #fagus #forest #ecology https://www.nytimes.com/2025/08/13/realestate/beech-leaf-disease.html?unlocked_article_code=1.gk8.hZkg.Px7C6OhdLFhW&smid=url-share

Been the last two days in a workshop on oriental beech, Fagus orientalis. A species growing from Greece to the Caucasus and probably the parental species from which our European F. sylvatica evolved. And there might be a possibility of it being perhaps slightly more drought resistant (choosing carefully my words here :-), but clearly more diverse, and therefore an interesting species to adapt our #beech #forests at critical sites to #ClimateChange. All in all an interesting two days with scientists and forest managers from different European countries

The unfiltered paper, with all the major deficits outlined by Kong's/New Phyt's #PeerReview experts still in it, is now online on bioRvix.

Being not limited, we moved a few more figures from the supplement to the main text 😎

#PhyloNetworks #reticulate #evolution

And, gravest of all deficits. We didn't cite the right people: "The references section is curious, and heavily cites a close network of workers in this organism [beech, #Fagus] while ignoring relevant work on reticulation in other groups [which?!], ... And just look at the date distribution of those citations [from 2002-2024]! Not sure I see even a single name I would consider a major player in plant reticulation or reticulation methods."
No major player, but impact we generate with beeches 😎

The #Europeanbeech #Fagus #sylvatica (#Fagaceae) is considered a very original #faunalelement of #CentralEurope and is still the most common tree in native #mixedforests. The #tree can live up to 300 years. During the last #IceAge, this tree species was only found in #refuges in #SouthernEurope, from where it subsequently spread northward again. #biodiversity #trees

A classic, my first paper on #beech #genetics getting a RG-#milestone: 1000 reads for "The #evolutionary history of #Fagus in western Eurasia: Genes, morphology and the #fossil record" RG added #reticulate #evolution, suppressed #speciation, could say that.

Low impact? Enduring research still (obviously) worth a read over 20 yrs later 😎

PS Still happy with it. But wouldn't just use a tree anymore for #phylogenetics

Quadrupling #beech biodiversity in Western Eurasia. What we started nearly 20 years ago waiting for our flight back home at Istanbul airport, finally out in print.

Small clump of honeydew eater (Scorias spongiosa) attached to the trunk of an American beech tree. The fungus feeds on the sugar-rich exudate that rains down from beech blight aphids (Grylloprociphilus imbricator). #nature #fungi #aphids #beech #trees #ants #fagus #mycology #entomology

Beech blight aphid (Grylloprociphilus imbricator) walking on a beech trunk. I think this is a wingpadded (alatiform), fourth-instar nymph, the type that acts as a soldier caste. They attack predators with their stylets and I can confirm that it hurts. #aphid #beech #fagus #hemiptera #insect #nature #entomology
