“The processions of icy monks” – a new type of habitat for psychrophiles in high mountains (”Procesje lodowych mnichów” jako nowy wysokogórski habitat dla psychrofili)

As it turns out, the more we learn about glacial ecosystems, the less we know about them. Glaciers and ice caps constitute 10% of lands, which is why the eyes of the world are anxiously looking at new reports of polar ice recession and its possible consequences for a civilisation such as flooding coastal cities. … Continue reading

Disappearing equatorial glaciers = disappearing cold-loving equatorial biodiversity (Znikające lodowce równikowe = znikająca zimnolubna bioróżnorodność równikowa

  Glaciation accompanied our ancestors in Africa 3 million years ago. The growth of ice caps in the northern hemisphere and global cooling led to the transformation of forests in Africa into savannas, and hominids (our ancestors) who had “left the trees” had to learn to live in the open area. The first people in … Continue reading

Position as PhD student in CoastDark project at Institute of Oceanology PAS (poszukiwany doktorant w projekcie CoastDark w Instytucie Oceanologii PAN)

Możliwość studiów doktoranckich w jednym z najlepszych instytutów biologii środowiska z wybitnymi polskimi ekologami morza. Biorąc pod uwagę rezultaty uzyskane w ramach projektów prowadzonych w Zakładzie Ekologii Morza PAN, wyniki badań prowadzonych w ramach doktoratu mogą być jednymi z  bardzo ważnych w zrozumieniu szybko zmieniających się ekosystemów morskich. Wszystko wymaga jednak pracy, ale za to … Continue reading

Who dominated ice-free oases of Antarctica? (Kto zdominował suche doliny na Antarktydzie?)

Can you imagine an area that is dominated by a single group of animals? A strange world without birds, roes, insects, vines, or even earthworms? The better we know our planet, the more it astonishes us. I have been recently surprised by areas where there are no vascular plants, no vertebrates, and soils are dominated … Continue reading

Radionuclides on glaciers (Radioizotopy na lodowcach)

Glaciers are not as pristine as we usually see them (or wanna see). Despite the fact they are located in remote places, as humans we keep leaving footprints in these peculiar, cold ecosystems. Nuclear weapon tests, disintegration of satellites or accidents in power plants such as Chernobyl resulted in contaminations from radioactive radioisotopes of caesium … Continue reading

Can small water reservoirs on glaciers be complex? Have a look at cryoconite holes/Czy prosta sadzawka lodowa może być skomplikowana? Spójrz na otwory kriokonitowe

At first glance, cryoconite holes are just water-filled reservoirs on glaciers which contain dark sediments on the bottom. This peculiar ecosystem seems to be simple: cyanobacteria and algae are responsible for primary production, then heterotrophic bacteria, ciliates and invertebrates use just produced organic compounds, or tardigrades and rotifers eat producers and bacteria. Usually, cryoconite holes … Continue reading
