Amazing (and prestigious) opportunity in Sweden: The Crown Princess Victoria Professorship in Biodiversity.
The announcement can be found here: web103.reachmee.com/ext/I005/103...
I've heard that the position will come with a lot of resources.

The team of (5) undergraduates that led this research project at an scenic lookout in Mo'orea, French Polynesia.

Super excited to share this work looking at seaweed trait differences across microhabitat! Proud of this team of undergraduates for working so hard to make get this paper published. onlinelibrary.wiley.com/share/author...

Bottom trawling to continue in English protected waters, government rules Defra says blanket ban on ‘destructive’ fishing practice disproportionate as MPs urge minister to reconsider

How very disappointing and backwards…

No drones, no AI, not very high-tech at all, only hard working people shaking and rinsing Ascophyllum to get all associated fauna out for biodiversity analyses 💪🏼🌱 #PhycologyFriday

Woah!...

Fig. 3. Estimated mitigation potential from forestation varies with land availability assumptions. (A) Global and regional ecosystem carbon sequestration. BA19 (10), GR17 (8), and Qin24 (24) refer to respective assumptions of land potentially available for forestation. The “committed” assumption considers only national commitments, and “achievable” shows currently achievable land limited by availability defined in Qin24 (see materials and methods section M3). (B) The currently achievable mitigation potential varies among countries and income groups. Country-specific data are available in data S3 (24). Country codes and corresponding income groups can be found in table S6.

The achievable carbon uptake from planting trees is much lower than previous estimates, and even lower than many nations have committed to. New paper by Wang et al. in Science. www.science.org/doi/10.1126/... 🧪🌏🌳🌲🌐

Yellowstone’s free-moving large bison herds provide a glimpse of their past ecosystem function Although momentum is building to restore bison across North America, most efforts focus on small, managed herds, leaving unclear how large, migrating herds shape landscapes and whether their effects enhance or degrade ecosystems. We assessed carbon and ...

The importance of large herds of mega-herbivores. Interesting paper in Science. #EcosystemFunctioning

Vi måste avverka mer för att kunna skydda mer skog? 🙃

That’s a lot of Ascophyllum!

”Utan intäkter från ett aktivt skogsbruk saknas resurser för skogsvårdande åtgärder och för att utveckla den biologiska mångfalden.”
Vad menas med ”utveckla” tro?

Ojoj, vilket inlägg i debatten om skogsbruk. Monokulturer och nya trädarter…

Once again on the “achievements” of the most right wing government in the history of #Finland. Sigh.

To warn others to learn from our mistakes.

On the left, government projections of new jobs (blue) vs the reality (red); on the right, distribution of tax cuts by income decile.

Greetings from Arctic Norway, 70.7°N. Tomorrow we go to one of our Ascophyllum sites to measure Asco properties, identify all species in frames and associated with the rockweed. Or aim is to compare structure, function and biodiversity in harvested areas with the unharvested control.

Not-so-mutually beneficial coral symbiosis The partnership between corals and their intracellular algal symbionts has long been a textbook example of mutually beneficial association. In this essay, Mikhail Matz argues for an updated view in which the coral acts more as a farmer of algal cells to support its own growth.

I missed this when it came out last September - excellent essay!

Läget är allvarligt för Sveriges biologiska mångfald.
Många av de arter och livsmiljöer som finns i Sverige är idag under stor press. Endast omkring 40 procent av arterna och 20 procent av livsmiljötyperna bedöms ha gynnsam bevarandestatus i hela landet.

CO2 X warming treatment in a tide pool. Black boxes on the high ledge hold batteries & circuit boards, with tubes leading to heating elements in the pool. The smaller black box generates CO2, which bubbles into the pool.

Just out in @jexpbiol.bsky.social: Great work by @racinerangel.bsky.social documenting effects of a 6-month factorial field manipulation of warming X CO2 on intertidal mussel shell thickness, strength, & corrosion. #SitkaNSF @cascadejbs.bsky.social journals.biologists.com/jeb/article/...

Can Resilient Species Keep Up? Climate Change Threatens Even Tough Seaweeds Fernando Lima, CIBIO/BIOPOLIS, University of Porto, Portugal, discusses his article: Simulated intertidal heat stress on the brown seaweed Ascophyllum nodosum demonstrates differential population s…

Climate change threatens even the tough ones. Our new study shows that even Ascophyllum nodosum, a tough brown seaweed, struggles with rapid temperature swings during low tides, and populations across Europe vary in their heat tolerance.

New paper out! 🌊 We show that southern populations of Fucus spp. are especially vulnerable to repeated low-tide heat stress — a key factor for their future under climate change.

Hot take.
Conferences should be at locations where as many people as possible can get as easy as possible (minimizing transportation and CO2 footprint), not where people want to take vacation.

A path towards appropriate degradation experiments for assessing carbon sequestration potential of macroalgae We systematically reviewed literature on macroalgal degradation. To date, most degradation experiments are carried out in aquaria or shallow environments, span short timescales or rarely incorporate ....

Unmasking the Sea Star Killer After a decade of carnage, we finally know what’s devastating sea stars along North America’s West Coast. Does that mean scientists can save them?

We are so proud of our sea star wasting work that came out today. This interactive article is very complete and includes beautiful videos.

I used to be a textbook neoliberal. But while doing my accidental PhD, I encountered too much evidence to maintain my former beliefs.
