Anthropic contaminants are accumulated, stored and released from glaciers (Zanieczyszczenia cywilizacyjne są akumulowane, a następnie uwalniane z topniejących lodowców)

Can you imagine the picks of the European Alps without glaciers? Such a dramatic scenario is likely to take place by the end of 2100. As a source of electric power, water for domestic use and a supply of water for downstream ecosystems mountain glaciers are of great importance. Currently, they are melting and release … Continue reading

Unexpected sources of iron for Antarctic marine ecosystems (Niespodziewane źródło żelaza dla ekosystemów morskich w Antarktyce)

What do you see when you think of iron? Probably bars, bridges, cars or plains. In general, the objects you can observe constitute some significant elements of a system we call industry and transport. This element however, is also essential to biological functioning of all organisms. It is crucial for a number of processes such … Continue reading

Bacteria on glaciers may degrade pesticides (Bakterie na lodowcach mogą degradować pestycydy)

At first glance, polar and high mountain regions appear as pristine and not contaminated areas, generally free from human impact. This illusion, however, was shattered by scientists a long time ago. Due to long-range wind transport, although far distant from their original sources, organic contaminants are present in both polar and mountain regions. They are … Continue reading

May glaciers and sea ice ecosystems on Earth be analogues to icy planets and moons? (Czy lodowce i lód morski na Ziemi mogą być analogią do księżyców i planet pokrytych lodem?)

May glaciers and sea ice ecosystems on Earth be analogues to icy planets and moons? (Czy lodowce i lód morski na Ziemi mogą być analogią do księżyców i planet pokrytych lodem?)

The Earth is not the only celestial body in the universe partially covered with ice. To focus on Earth’s glaciers as a habitat that can be similar to glaciers on other moons and planets has been of interest to astrobiologists for several years. Whoever has seen Christopher Nolan’s “Interstellar” should probably remember the icy planet … Continue reading

Why don’t invertebrates on the Greenland ice sheet (GrIS) reveal any association with their environment? (Dlaczego nie ma wyraźnego związku między zwierzętami a ich siedliskiem na czapie lodowej Grenlandii?)

Why don’t invertebrates on the Greenland ice sheet (GrIS) reveal any association with their environment? (Dlaczego nie ma wyraźnego związku między zwierzętami a ich siedliskiem na czapie lodowej Grenlandii?)

Usually, animals reflect a visible and clear association with their habitats. Typically, the selection depends upon food availability and the absence of predators. However, as opposed to some groups of invertebrates, especially those microscopical in size, these observations are confirmed and relatively well-known for big and well-visible animals. Due to a small size of some … Continue reading

Mosses hidden under glaciers for six hundred years are back to life (Mchy ukryte 600 lat pod lodem wróciły do życia)

In polar regions, mosses present one of the most numerous groups with respect to species diversity. Additionally, they constitute the greatest biomass of plants. They are both a habitat for a number of invertebrates and the main source of food for them (e.g. tardigrades, mites or springtails). Mosses are well-known for their high phenotypic plasticity … Continue reading

Pristine Greenland Ice Sheet is not so untouched – contaminants on the glaciers (Czapa lodowa na Grenlandii nie jest wolna od zanieczyszczeń)

Pristine Greenland Ice Sheet is not so untouched – contaminants on the glaciers (Czapa lodowa na Grenlandii nie jest wolna od zanieczyszczeń)

At first glance, polar regions are contamination-free but it is just an illusion. Arctic areas are influenced by anthropogenic pollutants such as radionuclides, heavy metals or persistent organic pollutants. POPs are organic compounds toxic for plants and animals. Additionally, they are resistant to environmental degradation. It has been already documented that all the pollutants exert a negative impact … Continue reading
