📢 Vacancy: I am urgently recruiting a PhD candidate to join a project on selection processes in pedunculate oak.
📅 Start date: no later than December 1st.

Well, I believe it’ll be more applicable than the binary concept in less studied taxa and regions, as it is less evidence demanding when it comes to questions like “how did the species arrive in the focal area” etc.

Thank you, Camilla Colding-Jørgensen for leading this important work, and to @jcsvenning.bsky.social and @r-ejrnaes.bsky.social for the collaboration, which was funded by the 15 June Foundation

Using the flora of Denmark, we show that a large proportion of species are treated as 'native' by one source and as 'non'native' by others, i.e. are of uncertain status. Using a graduated definition, most of these species end up in the 'near-native' category

Native and near-native species share most of their Pleistocene history. Are near-natives may well be our new natives under global climate change.

A graduated nativeness definition for overcoming dilemmas and difficulties of vascular plant species Nativeness is a concept central to biodiversity conservation and invasion biology, but there are several problems related to a classic binary nativeness definition. Dilemmas arise from the dynamic na...

Nativeness cannot be binary, if is to make sense and be practically applicable at the scale of countries.
We propose a graduated definition, in which species native to neighbouring territories are considered "near-native"

Bilbo Segge ville være misundelig (sorry, lousy joke)

Men ja, egentlig er det jo logisk nok. Alligevel tror 99% af den danske befolkning (og politikere) at biodiversitetskrisen skal løses ude på markerne. Den grønne trepart bygger 100% på at gøre ingenting i de officielt, men ikke reelt, beskyttede naturområder, men i stedet lave *skovrejsning*

Nja, bare at sandsynligheden for lokal uddøen er lige så stor inden for Natura2000- og §3-beskyttede områder som udenfor. De officielt beskyttede naturområder DK melder ind til EU og CBD er streger på kort uden reel virkning for de truede arter. Læs videre her:

"We show that unmanaged forests are the backbone of biodiversity conservation ... We conclude that to preserve forest biodiversity in Europe, we should increase the proportion of unmanaged forests and the amount of structures supporting biodiversity in extensively managed forests.

Just out in PNAS!

We used multi-taxon data to model virtual forest landscapes.

Forest withdrawn from timber harvesting are needed in a much higher share than they currently are in Europe, and extensive forests contribute less than expected to multi-taxon diversity.

Besser kann man es nicht zusammenfassen

Sweden and Finland have increased logging levels to such a point that their forests are now a net source of emissions.
Their Prime Ministers are asking to be exempt from EU #Climate target so that they keep going. Oh and they blame climate change.

Natürlich! Bien sûr!

Simple attributes predict the value of plants as hosts to fungal and arthropod communities Fungal and arthropod consumers constitute the vast majority of global terrestrial biodiversity. Yet, the link from richness and composition of producer (plant) communities to the richness of consumer...

Here is our original study. With the word "consumer" in the title, but in a completeky different meaning than a constumer in a webshop

I have also contacted the EiC of Review of Communication Research. They say they will pass on my report to the editorial staff. Let's see what verdict is reached there ...

I first got a message from ResearchGate: "Your work has been cited". When I realized the nature of that citation, I reported the fraudulent content to ResearchGate. Their response: "we have decided *not* to remove the reported content"

In their Table 2, the authors claim to summarize data from our paper and 14 others. But the figures do not come from our study of plants, insects and fungi (how could they?). The authors surely haven’t read, nor understood, our study. But much worse, their data must be considered *fabricated*

Disturbing citation
In 2022, we published a study on *consumers*, i.e. animals and fungi that consume biomass produced by other organisms, e.g. plants.
Now, our paper has been cited in what claims to be a metaanalysis of "Consumer Satisfaction in Live Streaming E-commerce". Far out!

It's a 100% bycatch, but I love it anyway 😍

60,000 Gazans have been killed. 18,500 were children. These are their names. Palestinian children have been killed at a rate of more than one per hour since the war began.

Minst 18 500 barn har dödats i Gaza sedan Israel inledde sitt försök att utrota den palestinska befolkningen. Washington Post har samlat och publicerat deras namn: www.washingtonpost.com/world/intera...

Hvis man vil vide hvor Helvede ligger, kan man tjekke artens udbredelse på GBIF. Det er tankevækkende her i feriesæsonen hvor mange danskere der frivilligt tager til Helvede for at slappe af 😉

We followed primary succession of arbuscular mycorrhizal fungi on a man-made island, Peberholm, 2010-2016. AMF communities diversified through more and more deterministic processes. They remained less diverse than on nearby island Saltholm.

Danmarks strategi for bæredygtig energi bygger i høj grad på biomasse. Det er et blålys, fordi det ikke mindsker udledningen af kuldioxid.

Og så har det den uheldige bivirkning, at det skaber økonomisk incitament til at ødelægge naturskove i hele verden - også i DK. Det sker med åbne øjne.

Come a join a vibrant new cross-disciplinary research project that may get immediate effect on the ground through the so-called “Green Tripartite Agreement.”

It's about sparing of large, contiguous areas for wild nature, reduction of GHG emissions and nutrient losses to freshwater and marine ecosystems, in order to stay within planetary boundaries downscaled to DK and meet agreed policy targets.
