I am a cytogeneticist and meiosis researcher. Our favorite objects are killifish of the genus Nothobranchius. We are always open to collaboration.

[Sergey Simanovsky @ssimanovsky]

We are happy to present our new preprint on meiotic recombination analysis in Nothobranchius virgatus: crossovers spans almost entire chromosome arms in a fully monoarmed karyotype! Is this typical of all Notobranchius or not? Further research will show =)

[Sviatoslav Sidorov @SviatoslavSido6]

Excited to share our preprint with @ssimanovsky and co-authors about male meiotic recombination patterns in an annual killifish Nothobranchius virgatus! -- https://t.co/INtHhJomhp
1. Fourth fish with profiled MLH1 binding.
2. Bimodal MLH1 distribution covers almost entire SCs.

Excited to share our new paper in @molecology on sex chromosome evolution in African killifish! 🐟 A great collaboration with @AlexandrSember! We uncovered ≥4 sex chromosome turnovers across Nothobranchius spp. using cytogenetics & genomics.

It’s been a while since I was last here! Last year, we published a simple yet important karyotype article on Epiplatys, a relative of Nothobranchius

[Comp. Cytogenetics @CompCytogen]

Researchers present the first karyotype description of Epiplatys spilargyreius and provide comments on chromosome evolution in the genus Epiplatys.

🐟 This paper aims to estimate the divergence of the #karyotype structure between and within the phylogenetically distant lineages of the family Distichodontidae.

Mormyrids are my second favourite fishes after Nothobranchius! Unlike nothos, mormyrids are practically unavailable for captive breeding, so all expeditions are great important. Congratulations to the authors on this achievement!

[Zuzana Musilova - FISHEVO 🇺🇦🇺🇦🇺🇦 @zuzmus]

Our new preprint on the charismatic mormyrids from Cameroon (Sanaga river)! It seems like species with longer snout tend to have higher signal in C and/or N stable isotope (=> different food source and higher trophic level) https://t.co/6P5AnRiwSz

Our new short report on #Cytogenetics for #EcologicalMonitoring. In our opinion, #Nothobranchius rachovii is the best laborotary model among fish for such studies!

In this paper, I was glad to contribute to the analysis of ASY1 and ZYP1 distribution in Allium meiosis.

@FishChromosomes In my opinion, the "Fish Chromosomes" group should contain papers on fish chromosomes :)

[Alexandr Sember @AlexandrSember]

Excited to share a great collaborative work on Nothobranchius cell lines establishment, where we contributed by cytogenetic evaluation of different lines and passages.
