The answer to the question in the title is: "Just send it to Science of the Total Environment, they'll take almost anything - no convincing of any editors needed..." They are known for publishing both good stuff and pseudoscience...

Seeing how important rivers, even smaller streams, seem to be for troop movements in the Russian invasion of Ukraine, one would expect the military to basically take over the whole river restoration operation...

Joacim Näslund @jnaslund.bsky.social · 6d

Is there any discussion about the military defence value of restored wetlands, rivers, forests etc. in Finland? I have tried to raise the issue a bit in Sweden, with some mixed responses (a general interest, but not really sticking in peoples' minds...)

New review paper titled "Balancing hydropower production and ecology - ecological impacts, mitigation measures, and programmatic monitoring" published in KMAE. With @jnaslund.bsky.social and others. Read it here: www.kmae-journal.org/articles/kma...

We have a list of all known observed species in Sweden. That could be a basis for searching e.g. newspapers, trying to temporally map the observations. At the very least, such an analysis would show that warm-water species have occurred over at least 150+ years.

Joacim Näslund @jnaslund.bsky.social · Aug 25

Yes, I think it has to be a qualitative analysis, with lots of dicussions around "effort"... records depend a lot on who is working where and when...

Joacim Näslund @jnaslund.bsky.social · Aug 25

There are some possible sources that I have not yet looked through, like the yearbook of the Gothenburg Natural History Museum... and newspapers!

Joacim Näslund @jnaslund.bsky.social · Aug 25

I'm working on a data set ;-) Not for that purpose though... The problem is that descriptive faunistic notes of rare species have basically disappeared from the northern European litterature since ca. 1970, creating a long period of data deficiency.

Joacim Näslund @jnaslund.bsky.social · Aug 25

...but it is also a heavily disturbed ecosystem from the fish community point of view, which could leave the area open for colonization.

Joacim Näslund @jnaslund.bsky.social · Aug 25

The now regular occurrence or even establishment of other species is more indicative I think, e.g. thinlipped mullet, golden grey mullet, surmullet, and tub gurnard...

Joacim Näslund @jnaslund.bsky.social · Aug 25

Possibly climate related, but the Skagerrak area has a long history of warm-temperate species popping up every now and then.
To name a few:
Antantic fanfish 1929
Blackspot seabream 1869, 1871, 1879, 1960
Little tunny 1909
Plain bonito ca. 1875
Bouge 1931, 1940, 1959
Oceanic whitetip shark 2004

Inviting a new reviewer at the end of a review process (when people drop out) seems unlikely - but I guess they also need at least two reviewer names on the front page... at least it is transparent that way. But likely some bias as they would look for reviewers that will accept...

Joacim Näslund @jnaslund.bsky.social · Aug 23

A major flaw in the Frontiers process (as it was when I reviewed) is, of course, that when a reviewer doesn't agree on publication and withdraw, then there is automatic consensus on publication among remaining reviewers... This possibly lets flawed manuscripts to pass... Maybe it has changed...

Joacim Näslund @jnaslund.bsky.social · Aug 23

My opinion on Frontiers is not positive either, for many reasons. Their process involves a review and a discussion stage with authors (at least a few years ago), and all reviewers have to agree to publication (or withdraw from the process). Reviewer names are then added to paper front page.

Joacim Näslund @jnaslund.bsky.social · Aug 23

Quite interesting. Review seems simlar to Frontiers' format (except 70% "voting" threshold for publishing, rather than 100%)? Actually not sure how it substantially differs from any other open-review journal..?

Not from the EU and looking to come to Sweden to do reseach? There is a grant for that! Applications taken through December 2025. www.vr.se/english/appl...

Couldn't they possibly just walk around it? See: doi.org/10.1016/j.be...

Have no recommendations, but I think PeerJ Preprints closed down several years ago...

Joacim Näslund @jnaslund.bsky.social · Jul 24

Det vanliga verkar vara att 1. nämna något om EBF-mål, 2. få kommentar om att vi inte är i närheten av EBF, och 3. hänvisa till att EU:s gemensamma fiskeripolitik inte tillåter EBF. Men då faller hela målbilden, så varför ens lyfta frågan... helt klart snömos.

Joacim Näslund @jnaslund.bsky.social · Jul 24

Stärker en tes som vi varit näst intill helt säkra på i minst 20 år... Varje gång någon hävdar ekosystembaserad- eller adaptiv förvaltning i sammanhanget havsmiljö/fiske (eller annan miljöförvaltning för den delen) så bör man protestera högljutt...

Joacim Näslund @jnaslund.bsky.social · Jul 22

1973 is even better. Very helpful! Thanks a lot!

Fish people! Does anyone have "Check-list of the fishes of the north-eastern Atlantic and of the Mediterranean (CLOFNAM)" (1979)? (unesdoc.unesco.org/ark:/48223/p...). I only need a photo of the synonyms of Atlantic salmon Salmo salar (no PDF needed). #CanIHazPDF #FishSci #TeamFish 🐠🐟🦈

Yet another brilliant blog post by @clauswilke.com in which he presents solid and carefully thought through argumentation on why deliberately publishing fewer papers may be a bad idea, hurting both quantity *and* quality of one's scientific output 👀

From the archives: No one reads your paper anyway

In 2013, I wrote a blog post about why it’s important to publish scientific results that nobody will read.
