some fancy Ascophyllum🌿

🌲 Boreal-tundra species drive Arctic plant borealization 🌲 Our new study in #EcologyLetters quantifies tundra plant borealization, assesses its main drivers and identifies the species & traits contributing to borealization. doi.org/10.1111/ele.... 🧵 (1/6) 🌐🧪🌱🌍

Sphagnum fallax in a mesotrophic sloping fen in central Germany 🌿

Its sometimes a narrow line between a "garden" and a protected boulder field with glacial relict species ;)

Sphagnum girgensohnii in an alder carr in southern finland :)

A collapsing Palsa in northern Finland; seen this week. Palsas are peat-covered hills, often a few meters high, that contains a core of permafrost. They are only found in areas of discontinuous permafrost 🧊, They will be likely gone soon due to climate change 🌿 nordia.journal.fi/article/view...

Botrychium boreale in coastal dune vegetation, subarctic norway 🌿🌊

Tundra office 🌿🍁

Have a nice weekend! Sphagnum cuspidatum 🌿

Sphagnum divinum at its best autom colors starting to sneak in 🍁🍂

Gymnomitrion species from the arctic tundra :) G. concinnatum, G. corallioides (with sporophyte), G. brevissimum

Have a nice weekend! Sphagnum tumidulum :)

small actions for local biodiversity :) our family´s garden got the award "bird friendly" by the Bavarian State Office for the Environment & the association for bird protection 🐦🌿@‪lbv-bayern.bsky.social‬ we implemented artificial nesting sites, many unmanaged corners, various native plants, etc 🥬

Lendemeriella tornoensis - a lichen parasting on mosses in subarctic snowbeds :) As far as I know those are the only pictures of this species existing on the internet. I took those during an excursion to Gistuskáidi late snow areas in subarctic Lapland, thx to Inka Kuusisto for showing :)

Sleepin´ beeauty

Ouch. “If we plan restoration targets to match future climatic conditions and consider state transitions of currently natural ecosystems due to climate change, the potential for natural climate solutions related to ecosystem restoration is close to zero.”

Qvidja Bioblitz, really nice and diverse cultural landscape around an old castle. Even Apollo butterflys there! #Qvidja

It's the #WorldBogDay! Let's protect & restore #peatlands.

Have a nice weekend, Sphagnum tenellum :)

It doesn't take a scientist or forester to see that North America's forests are changing rapidly, sometimes in ways never seen before. For this #ForestFriday let's review some terms being used to describe these changes, & take a tour thru America's new 'Forests of the Anthropocene'. 🧵

When you BLAST plant but fungi comes out there seems to be Antarctic Yeast (Sporobolomyces roseus) on the plant sample ?? :))

Some mire specialist dragonflys :) Leucorrhinia dubia (m and f) Leucorrhinia pectoralis Leucorrhinia rubicunda

Valdensia heterodoxa, a blueberry pathogen currently spreading over Finland - strange species with a single, ultra large Conidia! The fungi likely gets more common with warmer climate, less precipitation and higher nutrient load in the environment. In the national news: yle.fi/a/74-20172542

Libellua quadrimaculata detail of wing shortly hatching and after few days :) all images from quite recently restored fen

What if you take a weird ancient lycophyte, give it desert-plant-style photosynthesis, and throw it in a cold lake? You get Isoëtes lacustris

Sphagnum violascens, a nice pinkish species found in south africa and close islands :) images from la Réunion island, dry ombrotrophic bog at about 1544m alt.

Found Botrychium lunaria today on a gravel pile at the university parking lot - strange habitat. 🌿 Happy weekend! 🌿

Very cool paper! It is shocking how few forest areas in Europe are not managed www.sciencedirect.com/science/arti...

Measuring Photosynthetic gas exchange with Li Cor on different mountain birch varieties from subarctic Finland🌳

when the sequencing machine hates you:

Acaulon muticum - a species that hasnt be seen in Finland for about 90ys growing in a grazed coastal oak forest in the Turku archipelago 🌿

Field work on the Åland islands (between Sweden and Finland), a strange mix of lush Orchid rhich grazed forests, coastal meadow vegetation and plain open granite expand

extracting DNA of some Tortella spec, a genus that has been recently changed a lot, with quite some new species, such as Tortella angustifolia; a species with very dense papillae structure on the leaf cells :)

A bit late, but happy (belated) International Day of Taxonomy! 🧬🔍 Taxonomy reveals hidden diversity and reshapes how we understand species and conserve biodiversity. Me, staring at Tortella tortuosa—now 8 species in disguise 👀 (Köckinger & Hedenäs 2023) www.facebook.com/permalink.ph...

back to Fieldwork in the boreal bogs, with a boreal bog dog :)

Plenogemma phyllantha, a very odd species that mass produces gemmae and is the only sp in its genus found in SW-Finnland on coastal rocks

Dicranum leioneuron, a species with unusual looking flaggela, growing in open raised bog with a small stream running through, creating an interesting nutrient gradient :)

Field work in the subarctic tundra, in August and in March (same location) :)

Different forms of Sphagnum angustifolium, dont trust the look ;) it can even get sphaerical

Sphagnum medium in a sloping bog on granite slope, in the hemiboreal zone (southern Finland)

Sphagnum quinquefarium ⭐

ultra-endemism Fissidens ah-pengae, an endemic moss that grows on edemic trees in one of the last remnants of primary lowland rainforest in the mascarenes. about the forest: mosssoup.blogspot.com/2023/11/tiny... www.inaturalist.org/observations... #biodiversity

Polytrichums from around the world, P. commune, piliferum, hyperboreum, subpilosum

Splachnaceae mosses grow on dung and carcasses, luring flies with smells and colors to spread their spores. Their insect-powered strategy, on display in Finland’s Sompasammalet project, reveals a rare case of entomophily in mosses. mosssoup.blogspot.com/2025/04/the-...

Phaeoceros carolinianus is a hornwort with symbiotic nitrogen-fixing Nostoc, and algal-style photosynthesis. Simple yet sophisticated, it offers key insights into the early evolution of land plants. mosssoup.blogspot.com/2025/04/phae...

Fissidens exilis, a small Fissidens species pioneering on open loam :)
