Glaciers, „melting” ecosystems still awaiting descriptions (Lodowce, „topniejące” ekosystemy wciąż oczekują poznania)

  Since its very beginnings, human curiosity rushes towards recognition and description of the surrounding environment. The best examples are wall paintings in the caves, where the first human hoards lived. These wall paintings are regarded as the first pieces of art. Yet, in my opinion, they are a kind of notes from environmental observations, … Continue reading

Antibiotic resistance genes stored on glaciers (Geny oporności na antybiotyki przechowywane na lodowcach)

The rapid growth and permanent spreading of resistance to antibiotics among bacteria is an unquestioned global problem and according to the World Health Organization, one of the most serious threats of the 21st century. Currently, drug-resistant diseases cause at least 700,000 deaths globally per year and it is estimated that this number will increase to … Continue reading

An alpine glacier: black tardigrades, microplastic and other interesting facts (Czarne niesporczaki, mikroplastik i inne ciekawostki na alpejskim lodowcu)

Forni Glacier. Lodowiec Forni. For a biologist who works on organisms and biological processes on the surface of glaciers the season is definitely over. This means it is time to write about the last expedition to Forni. The Forni Glacier is one of the largest glacier located in the Italian part of the Alps. When … 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

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

Interdisciplinary expedition to the Forni Glacier (Interdyscyplinarna wyprawa na lodowiec Forni)

I have heard about the Forni Glacier in the Italian Alps a long time ago. Probably I would have never paid any attention to this particular glacier but I heard about it thanks to an interdisciplinary group of scientists from Italy. It was on Forni where the team discovered that “ice” bacteria may degrade pesticides … 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
