The Konrad Lorenz Institute of Ethology is a biological research institute for the study of animal behavior. Ethology (or Behavioral Biology) is an integrative field that addresses questions about how and why animals do what they do. Since spring 2015 it is also the headquaters of the Österreichischen Vogelwarte/Austrian Ornithological Centre (AOC).

Vetmeduni Vienna Open House 2017 on 10 June

Visitors can look behind the scenes at the Vetmeduni Vienna on the open house day. The two research institutes of the Department of Integrative Biology and Evolution are also presenting a number of exciting wildlife-related topics. Are you interested in urban wildlife? Want to learn more about the resettlement of the ural owl in Austria? Would you like to know about dormice and co.? Have always wanted to know how genetic investigations are used in wildlife forensics? Would you like to "fish" for cichlids in Lake Tanganyika or track migratory birds? Or test your noses and ears with fragrances and songs from the animal kingdom? Then you are in the right place at our information stands. Or go "speed dating" with our researchers at the Science Café [Link 2] to find out about dromedaries and camels, colours in the animal kingdom, or "goblins of the night". In addition, young visitors can try their hands at drawing and making animal crafts with our creative team.

The whole programme  [Link ]is available online.

When: 10am to 5pm

Where: Veterinärplatz 1, 1210 Vienna

Smelly feet as a signaling device

Graphical abstract. The study demonstrates that brown bears do have pedal glands that produce specific and sexually dimorphic scent, and display behavioural patterns related to pedal marking. (Drawings by Katarzyna Chrząścik for Scientific Reports 7, Article Nr. 1052, Fig.4).

Brown bears in the wild walk long distances and are not territorial. Researchers from Poland, Spain and Austria have now discovered that while walking they spread smell signals via their foot prints. They discovered 26 different chemical components in the sweat glands of the bear paws, 6 of which were found exclusively in males. The bears also use a special gait from time to time, a kind of "marking dance", in which they produce deep footprints. The scientists conclude that the foot odor in the bear world serves for intra-species communication between individuals, the smell being an olfactory and the footprint itself a visual message. Chemical signals are also found in many other mammals. They can provide information about identity, gender, territory, social status, reproductive readiness, or group affiliation. In addition to their soles, bears also use other methods to leave their odor, e.g. tree rubbing. The marking behaviour was frequently observed, particularly during the mating season. It is therefore probable that bear foot odour is also used to give female bears information about the attractiveness of possible partners.

The study was conducted by Agnieszka Sergiel and Nuria Selva from the Polish Academy of Sciences. Johanna Painer from the Department of Integrative Biology and Evolution procured the bear samples for histological examination.

Departure of migratory birds from stopover sites is hormone-controlled

Migratory birds often stop along their long journeys to replenish their fat stores. The purpose of these stopovers – rest and refuelling – is clear. To date, however, it had been unclear which physiological signals triggered the birds’ decision to continue their flight. A team led by researchers from Vetmeduni Vienna has now identified, for the first time, the hormone ghrelin as a signal for the birds’ brains. Ghrelin, which is known to be an appetite-regulating hormone in humans, was measured at high levels in satiated garden warblers. Moreover, birds injected with additional ghrelin exhibited decreased appetite and increased the highly active state of migratory restlessness. The results, which were published in the journal PNAS, confirm the hormonal influence on avian migratory behaviour and could even lead to an improved understanding of eating disorders among humans.

The article “Ghrelin affects stopover decisions and food intake in a long-distance migrant [Link 7]” by Wolfgang Goymann, Sara Lupi, Hiroyuki Kaiya, Massimiliano Cardinale und Leonida Fusani was published in PNAS (Proceedings of the National Academy of Sciences of the United States of America).

Major Urinary Proteins do not allow kin recognition in male mice

Male house mice produce large quantities of proteins called ‘major urinary proteins’ or MUPs, which transport volatile pheromones to urine and stabilize their release from scent marks. Many studies have concluded that MUPs provide a unique individual signature or ‘barcode’ and thereby control individual and kin recognition. Researchers from Vetmeduni Vienna now found evidence that directly refutes this hypothesis. They discovered that the MUP genes of wild house mice show a surprising lack of variability, and rather than providing a stable barcode, individuals dynamically regulate the number of MUP excreted depending upon social context. These findings contradict the widely assumed hypothesis that MUPs control kin recognition.

The article "Diversity of major urinary proteins (MUPs) in wild house mice [Link 10]" by Michaela Thoß, Viktoria Enk, Hans Yu, Ingrid Miller, Kenneth C. Luzynski, Boglarka Balint, Steve Smith, Ebrahim Razzazi-Fazeli, and Dustin J. Penn was published in the journal Scientific Reports.

The article "Regulation of highly homologous major urinary proteins in house mice quantified with label-free methods [Link 11]" by Viktoria Enk, Christian Baumann, Michaela Thoß, Kenneth C. Luzynski, Ebrahim Razzazi-Fazeli, and Dustin J. Penn appeared in the journal Molecular Biosystems.
