PhD studentship in tardigrade evolution

  Fully funded 4-year PhD studentship in tardigrade evolution at the Jagiellonian University in Kraków (Poland) in the team of Dr. Łukasz Michalczyk. The main goal of the project is to test how reproductive mode and cryptobiotic abilities affect dispersal and, in consequence, speciation and extinction rates in tardigrades. Tardigrades are a phylum of microinvertebrates … Continue reading

Hidden microworld – anoxic zones on the surface of glaciers (Ukryty mikroświat – strefy bez tlenu na powierzchni lodowców)

So far, the surface of glaciers was regarded as only aerobic zones due to high biomass and production of algae. On the white surface of ice shimmering in the sunlight we can see dark wind-transported dust, cryoconite holes (water-filled depressions in the ice with dark sediments on their bottom), sometimes ponds, cracks or wells. Would … Continue reading

Enigmatic black tardigrades on Central Asian glaciers (Enigmatyczne czarne niesporczaki na lodowcach Azji Centralnej)

Tardigrades also known as water bears are a group of microscopic metazoans of average size equal to 0.3 mm. Under a microscope they resemble a sausage or a microscopic bear with four pairs of legs. Tardigrades can be found at all latitudes. They inhabit deep seas, high mountains, remote deserts or soils and mosses opposite … Continue reading

Ice Alive (Żyjący Lód)

Dear readers, please see amazing video made by Joe Cook (author of biocryomorphology) and legendary Chris Hadfield (first astronaut who sang “Space Oddity” beyond the Earth). This excellent movie explain importance of glacial biology in a nutshell. Enjoy the film! Ice Alive (Żyjący Lód) Drodzy Czytelnicy, zobaczcie niesamowite wideo wykonane przez Joe Cooka (autora biokryomorfologii) … Continue reading

Tardigrade species new to science found on a disappearing African glacier (Nowe gatunki niesporczaków na znikającym lodowcu w Afryce)

Glaciers can be found not only in polar regions, the Alps or the Himalayas but also in the equatorial zone. Unimaginable as it may seem, glaciers in the equatorial zone exist on high mountain tops (e.g. Kilimanjaro) and they constitute cold islands surrounded by warm environments. Unfortunately, recent ice mass changes and ice melting models … Continue reading

What has changed in glacier cyanobacteria during the last 12 500 years? (Jak zmieniły się sinice żyjące na lodowcach w ciągu ostatnich 12 500 lat?)

For those of you who are interested in polar or mountain biology even to a small extent, it is obvious that glaciers are inhabited by various organisms. Cyanobacteria play a crucial role among them as primary producers which provide heterotrophic organisms such as bacteria and microfauna with carbon. Cyanobacteria are hardly demanding organisms. In harsh … Continue reading
