Humbled to receive a Special Award from Živa Magazine for 2025! It was inspiring to connect with scientists so dedicated to comunicating their exciting fields. Živa has been popularizing biology since 1853—predating even Nature and Science. Truly an honor to be part of this legacy.🌿 #ZivaMagazine

Sexual selection and reproductive success in mesocosm populations of African annual killifish doi.org/10.1111/jfb.... @fishjakub.bsky.social

Interesting reading - Bluesky becomes scientists favourite platform over X, due to lack of hatespeach, conspiracy theories and pseudoscience, a survey among 800 scientists show doi.org/10.1093/icb/...

I invite you to check our paper entitled “Rebuilding Ukraine’s capacity for fundamental research in evolutionary biology” doi.org/10.1038/s415... in @natecoevo.nature.com about the Ukrainian School in Evolutionary Biology #USEB we organized in 2025. #biology #evolution #school #science #Ukraine

Desert lizards consumed and retained more carbon before hibernation and more nitrogen during breeding season, surprisingly by including insects to their otherwise plant-based diet. Read 'Desert lizards modulate nutritional responses to match seasonal biological needs': doi.org/10.1098/rsos... #RSOS

#JFB: Cold storage of alarm substance reduces the behavioural stress response of zebrafish (Danio rerio) doi.org/10.1111/jfb.70200#JFB#FishSci

New paper! We challenge the universality of dietary restriction for lifespan extension! It works for inbred but not for genetically diverse populations. In outbred Nothobranchius furzeri, neither protein nor caloric restriction delayed actuarial senescence #AgingResearch

Amazing talk by Jason Podrabsky (@OregonStateU) as part of the Life Sciences Seminars at MU, on the incredible stress tolerance of annual killifish (Austrofundulus limnaeus) embryos! These tiny survivors endure extreme conditions that would kill most other life forms

Computer scientist Yoshua Bengio has become the first person to have their work cited more than one million times on the search engine Google Scholar go.nature.com/4i1L2Gq

Přirozený výtěr tolstolobika v Dunaji! Znáte ty obrázky z USA, kde kolem člunu létají desetikilové ryby? Tak už i na Slovensku. Je ho v Dunaji tolik, že Slovenský rybářský svaz spouští redukci. Více od 57. sek: www.stvr.sk/televizia/ar... #tolstolobik #Dunaj #invaznidruhy

Must read! Nice examples why basic science is important and how we all benefit from it www.nature.com/articles/d41...

Symposium on Fish Mating Systems (Czechia, 21-23 Jan 2026): REGISTRATION NOW OPEN at fish.ivb.cz/registration/ Plenary talks by Suzanne Alonzo, John Fitzpatrick, and Chiara Benvenuto. @ivb-cas.bsky.social

Husbandry of N. furzeri, the shortest-lived vertebrate used for biogerontology, is dependent on bloodworms. When our protocol is followed, you can feed N. furzeri an open-formula purified diet — paving the way for more consistent and reproducible lab studies. #killifish @thefsbi.bsky.social

Vysokohorské ryby v Evropě? Kde? Proč? a Jak se tam dostaly? Více v odpovědi pro Zeptej se vědce shorturl.at/0RrVO

Jedna z našich nejvzácnějších a nejkrásnějších rybek, sekavčík balkánský. Byl znám pouze z jedné říčky při hranicích se Slovenskem. V r. 2016 byla nalezena velká populace v řece Jihlavě. To jen podtrhuje důležitost ichtyologických monitoringů

What determines mitochondrial number in Ethiopian Rodents from two Mountain regions? Species? Tissue? Elevation? @botzool.bsky.social @ivb-cas.bsky.social doi.org/10.25225/jvb...

I fear there is deep truth here.

An interesting reading. Dietary restriction is intensively using mice as a model. Wheatley et al suggest that mouse physiology may considerably confound the real effects of dietary restriction, meaning that mice may not be the ideal model for studying DR link.springer.com/article/10.1...

We published a visual guide to the repertoire of hepatocyte alterations recognized in Nothobranchius furzeri, a vertebrate model in aging research. Giant mitochondria and intense hepatocellular vacuolation are the most prominent features. #killifish

Interested in Fish Mating Systems? Join us for a small symposium in Brno, Czechia, from 21 to 23 January 2026! The invited speakers are Suzanne Alonzo, John Fitzpatrick, and Suzanna Pla. More information at fish.ivb.cz

Zpět z Německa, kde se konala konference o halančíkovi a jeho využití jako modelového organismu. Unikátní možnost podělit se o výsledky studia potravní preference halančíků

Je chov halančíků standardizován? Jaké jsou mezery? To vše v závěrečném dílu o laboratorních halančících nyní v Živě.

Od ledna má Ústav botaniky a zoologie MU nového ředitele. shorturl.at/aa7Ua

Happy 20th anniversary to #BiologyLetters! Take a look at our timeline of key milestones for the journal over the past 20 years. royalsocietypublishing.org/pb-assets/BL...

Larger species have a higher cancer prevalence than smaller species, according to a study that refutes Peto’s Paradox, the claim that that species’ body size is not correlated with cancer risk. In PNAS: www.pnas.org/doi/10.1073/...

Aha, tak oni jsou statisicove odmeny nekolikrat do roka asi standard, kdyz jste rektor.

Loving deep-sea fish and molecular evolution? We're hiring!:-) Looking for a motivated PhD student to join us to study evolution of vision & to explore limits of vertebrate eye in extreme environment. Deadline 15th March. Thanks for applying and sharing! more info: www.fishevo.com/erc-funded-p...

Vedení univerzity je jistě nelehká věc a zaslouží adekvátní ohodnocení. Ale nevím, jak často si “řadový” akademik přijde na odměny v řádu vícenásobků jeho mzdy. Ale je třeba prijem nasobit, když je 175 tis kč/měs?
