Third report of 5 Arctic expedition FS USB

Press news

5th Expedition Science University of South Bohemia in the Czech Budejovice in the Norwegian Arctic archipelago of Svalbard; course wildlife.

21st July last students leave the course inanimate nature. We have two days to cleaning stations and to prepare the next course. Saturday 23 July welcomes the entire crew on the pier in the port Pyramiden nineteen of the participants Polar wildlife ecology (Fig. 1 – top row from left – J. Klimešová, J. Komarek, O. Strunecká, M. Dvoracek, V. Paul, M. Devetter, Kavan, E. Janková, K. Janko, O. Dietrich, J. Těšitel, J. Elster, L. Bučinská, T. Tyml, S. Mass, M. Tušer, J. Kvíderová, the bottom line – E. Kašparová, M. Lučanová, A. Kodátková, V. Špátová, T. Raspberry, A. Bernard, L. Raabová, I. Lacmanová).

Also the second part of this year's program includes specific scientific programs, which closely follows a course Polar ecology – fields of wildlife; Microbiology – phycology, Botany – Plant Physiology and Zoology – Parasitology. More information is also available on our website (www.polar.jcu.cz). In these fields in the Bay of Petunia doing research for five years, so most of the field of topics based on our previous experience.

Phycological group maps the diversity of cyanobacteria and algae in terrestrial and freshwater habitats (Fig. 2). After collection of samples followed by microscopic and documentation of the dominant groups of cyanobacteria and algae (Fig. 3). Based on a detailed study of diversity, we have identified several freshwater and soil habitats in which we installed data loggers, which we record the temperature every hour. For even more detailed study of growth ekofyziologickému green filamentous algae Zygnema we chose a shallow wetland (seepage), which is located in front of the station (Fig. 4). The population of algae have over two-hour periods two days measured diurnal changes in photosynthetic activity in relation to changes in irradiation.

Botanists carefully map the onset of vascular plant vegetation on the newly odledněná all glaciers flowing into the Bay Area Petunia (Fig. 5). This topic is dealt with in recent years prof. Dust in collaboration with colleagues from the University of Poznan. Poznan University of Geographers monitor retreats of glaciers since 1984 and their shrinking glaciers dating provides a unique record of environmental changes Petunia Bay.

Unlike previous seasons zoological – parasitological group expanded its range of measurement in the study of soil and freshwater invertebrates, particularly in relation to gradients away from the front of glaciers and altitude gradient (Fig. 6 and 7). At the same time this group has traditionally been devoted to collecting marine invertebrates and fish with the help of diving and hunting with nets (Fig. 8). Catches are then subjected to determination (Fig. 9) and parasitological dissection (Fig. 10 and 11).

4th August ends year zero rate Polar ecology. A group of students leaving and it turns off other researchers. Their work will inform you in another report.
