We started the mark recapture project of florivores in Latnjajaure. Bombus lapponicus is so far the most common and truly beautiful but a species which previously was really rare at this elevation.

Fantastic new paper on casual inference in ecology research. So much great information. I think it is a must read for all ecologists.

Ecology needs a causal overhaul
Ecology has yet to embrace causal inference, yet most questions in ecology are causal. Despite the common use of terms that imply causation, such as “shapes”, “drives”, or “impacts”, many studies shy...

Insekten-Oasen in der Stadt: Auf urbanen Brachflächen gibt es genauso viele Insekten wie in Naturschutzgebieten. 🐞🐝🪰 Bei Wildbienen sind sie sogar beliebter als die Schutzgebiete. Das zeigt eine neue Studie der Uni Halle. Die Ergebnisse liefern wichtige Hinweise für den #Artenschutz. mlu.de/2ewg5

Excited to see this out!! In this thought-provoking review led by @davidperis.bsky.social and Ricardo Pérez-de la Fuente we further demonstrate that insect #pollination was once widespread among #gymnosperms and existed long before the origin of #angiosperms

3. The increase in polyploid frequency with latitude could be explained by patterns in plant reproduction, especially the frequency of self-reproduction, rather than higher tolerance to abiotic stress as commonly suggested.

📢 Viewpoint in New Phyt. on polyploid establishment!
Key take-homes🧵
1. In contrast to earlier hypotheses that pollinators can help new polyploids establish, we suggest that pollinators mainly prevent polyploid establishment because outcrossing increases the strength of minority cytotype exclusion.

That is cool! Certainly more work is needed to grasp bee conservation, and a synthesis is needed!

📢 New study: Insect Biomasse & abundance were similar in protected areas & urban wastelands, but 🐝wild bee diversity was higher in urban areas! Protected areas (Natura 2000) may need targeted management to support pollinators.

I wrote (ranted) on experimental design as I was frustrated as an editor at how little guidance students were getting. I underestimated the interest in the issue: it has been downloaded 10,000+ times! Clearly it’s something we need to be talking about more. onlinelibrary.wiley.com/doi/full/10....
Principles of experimental design for ecology and evolution
Here I argue that we do not discuss experimental design, often until it is too late. This editorial seeks to begin a conversation about how and where to replicate appropriately.

The population is monitoried some, but there is no restoration. It also appears to be grazed, so some protection effort may help. It is on the border to Norway where they have some more populations but they have been in decline.

A special moment was spotting one of the rarest plants in Sweden ”Gentiana purpurea”. One single population in the country with 5-20 individuals flowering per year. Would be great to know more about the pollination of the species - at this time a single individual flowered

We could/should just call it realized outcrossing rates. Regardless of opinions about pollinators. It carries confusion and ”system” really means something else in any other context. A system where e.g rain impacts the outcome makes no sense :)

Indeed. It is a confusing terminology (see it misused alot). ”System” refers to a property of something, of which the outcome may be affected by the environment. But the environment is not a part of the system. It may seem nitpicky but this term affect how biologists think about pollination alot.
