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

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

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

How to track an invisible system – particulate organic carbon may reveal the evolution of subglacial drainage (Jak badać niewidzialny system – cząsteczkowy węgiel organiczny może pokazać jak ewoluuje system rzek pod lodowcami)

Carbon is a basic element of life on our planet and all the molecules which build us contain it. One of the kinds of carbon often tracked in ecosystems by scientists is POC – particulate organic carbon, whose size does not allow it to pass through a filter measuring e.g. the physicochemical properties of water. … Continue reading
