RHEV Helsinki strains clustered together with strains from South Korea and Spain, but polytomous phylogenetic trees and large branch lengths suggest lack of sampling. Our genotype RHEV-C1 has been reported to cause mild liver dysfunction with human case reports from Hong Kong, Spain, and France.

Just out of press: genetic characterization of rat hepatitis E virus in Helsinki rats in Archives of Virology!

Earlier we reported that we found RHEV in four of our rat carcasses (prevalence of less than 2%) and now we have complete or partial genomes for these.

Genetic characterization of rat hepatitis E virus (Rocahepevirus ratti) in urban brown rats (Rattus norvegicus) in Helsinki, Finland - Archives of Virology

We report complete and partial genome sequences of rat hepatitis E virus (RHEV, Rocahepevirus ratti), from archived brown rats captured in Helsinki, Finland. Phylogenetic analysis confirmed the presence of the pathogenic RHEV genotype C1 in the Helsinki region. Finnish strains clustered together with strains from South Korea and Spain. However, the polytomous topology of phylogenetic trees and the large genetic distances between spatially distinct strains suggest that RHEV has remained inadequately sampled on a global scale. Further surveillance of rocahepeviruses is needed to assess their threat to public health and to understand their diversity and evolutionary patterns.

The research might be "eclectic disciplinary perspectives", but as Riikka aptly summarizes: "Urban stigmatisation and marginalisation are multispecies processes that emerge with place-making and have consequences for all the multispecies cohabitants of the city."

Waste, humans, rats - junk food, shopping centers, drunk people. "Well, this just happens to be a place where people randomly poop around, business as usual."

Belonging and place-making are multispecies phenomena, and urban is not only human, but more-than-human.

With this invisible rat presence, we examined urban stigmatisation and belonging as examples of societal phenomena which can be rethought as multispecies. They are very territorial in scope, and place-making emerged as a fruitful concept to understand how multispecies urban is formed.

We (as in the ragtag bunch of researchers in CitiRats project) went out to look for rats with lower secondary-school students and we did not see any rats, but we did felt their hidden presence. They were present in stories, stereotypes, memories, and athmospheres.

‘Ik ben ecoloog, dus ik probeer ratten niet te zien als een plaagdier.' Ik weet dat dit provocerend klinkt, want ecologen zijn goed in het beoordelen (en doden) van andere dieren.
Mare interviewde mij over ons rattenonderzoek en het samenleven met vervelende dieren: www.mareonline.nl/wetenschap/r...

Plaagdieren? Welnee! Ratten zijn onze vrienden, betoogt Finse ecoloog

Mensen kunnen vreedzaam samenleven met ratten, betoogt ecoloog Tuomas Aivelo. ‘We geven gemengde signalen af.’

Mielenkiintoista uutta tutkimustietoa rotista 🐀 by @helsinkirats.bsky.social: alustavien tutkimustulosten perusteella rottien määrä on yhteydessä alueen sosioekonomisiin tekijöihin, mutta syitä ilmiöön ei vielä tunneta. #tutkimus #kaupunkieläimet

Tutkija osaa päätellä asukkaiden perusteella, onko alueella paljon vai vähän rottia – taustalla tuore tutkimus

Asukkaiden taloudellinen ja sosiaalinen asema on yhteydessä rottien määrään Helsingissä. Tarkkaa syytä ilmiölle ei vielä tiedetä.

Happy to talk with @politiken.dk about rats, and apparently disagree with the whole of Denmark.

I've cycled through the streets with dead rats brushing against my leg. And now I'm obsessed

They live in our parks, basements, and dine with us at restaurants. Despite spending more and more money to eradicate them, Copenhagen’s rats have already won. Have we completely misunderstood the urb...

The most interesting finding was that almost any species or reason could either lead to increase or decrease of feeding, depending on the context.
A lot of people like to go against the grain: when everybody else stop feeding due to rats, someone doubles down and feeds more. 7/8

People described a number of reasons to increase feeding such as caring for endangered species, empathy or interest in birds, keeping up traditions, supporting biodiversit or wanting to provide nature connection to children or cats looking behind the window. 5/8

There are many papers on the motivations to feed birds and how bird-feeding affects bird and non-avian communities. There are less studies on how communities at the bird-feeder affect the feeding practices and the first peek of the dat seems to show that that's where the drama happens! 4/8

Bird-feeding could be the most common human-wild animal interaction in the Global North.

My colleagues collected an impressive dataset on changes in bird-feeding and rats were one of the major reasons to reduce feeding so I was asked to collaborate. 2/8

"Ajattelemalla jälkilevyä rottien ja ihmisten yhteistyönä, tieteellisen tutkimuksen painopiste siirtyy tiedontuottamisen prosesseihin ---. Tällainen näkökulma antaa tilaa huomata maailma ihmistä ja ihmiskeskeisyyttä laajempana", sanoo @aivelo.bsky.social

Millainen on rotan rooli kaupunkirottatutkimuksessa? | Kaupunkirotat | Helsingin yliopisto

On kuitenkin esitetty, että planetaarisiin kriiseihin kuten biodiversiteettikatoon vastaaminen edellyttää ihmisen ja muun luonnon hierarkkisuuden purkamista. Voisiko ekologinen tutkimus auttaa?
