Bear news - the first project bulleting of LIFE DINALP BEAR
The Research Institute of Wildlife Ecology is one of 9 regional project partners in the EU Project LIFE DINALP BEAR [Link 2]. Together with partners in other countries in the regien our goal is to further scientific knowledge on the slowly progressing spread of Slovenian brown bear populations, partly also into Souther Austria. The first project bulletin "LIFE with bears [Link 3]" is now available for download on the official project website [Link 4]. One of the artciles describes the current situation of bears in Carinthia (p.15).
Recently a label of "bear friendly" products [Link 5] was created. Products are now available to purchase - maybe an idea for one or the other small Christmas present?

Prof. Dr. Walter Arnold nominated as "Austrian of the year" in the area of research
The Austrian daily paper Die Presse asks its readers every year to vote on the "Austrian of the year". Men and women are nominated in several categories, if they have achieved something important for Austria in their area. This year our head, Univ. Prof. Dr. Walter Arnold, was nominated in the area of research.
He was voted among the top 3 by the Presse readership. Although in the end the prize in the area of research went to the waste researcher Marion Huber-Humer (BOKU), the nomination itself is an honour for the Instiute and for Prof. Arnold.

Theresa Walter wins 3rd place at the Vetmeduni Science Slam
The first ever Science Slam of the Vetmeduni Vienna took place on 15 October. Researchers of the university made short and lively presentations, competing for the audience´s favour. After a clicker-vote the winners were determined and awarded a prize by the rector´s office.
Theresa Walter of the Research Institute of Wildlife Ecology presented her urban fox project. She is researching where and when red foxes are seen in Vienna. She shares third place with two other researchers who won the same number of click-votes. Congratulations to our young scientist!

Lazing away the summer - Some dormice start their hibernation early
Typically hibernation is expected to occur during winter. It is all the more astonishing that wildlife biologists from the Research Institute of Wildlife Ecology of the University of Veterinary Medicine, Vienna have shown for the first time that dormice can enter hibernation already in June or July. However, they do not do this every year. Rather, they choose to hibernate when successful reproduction and rearing of their offspring is not possible. Early hibernation in this case serves as a strategy to decrease the risk of predation.
The article „How to spend the summer? Free‑living dormice (Glis glis) can hibernate for 11 months in non‑reproductive years [Link 9]” by Franz Hoelzl, Claudia Bieber, Jessica S. Cornils, Hanno Gerritsmann, Gabrielle L. Stalder, Chris Walzer and Thomas Ruf was published in the Journal of Comparative Physiology B [Link 10].

Nightly human-fox encounters – foxes sighted mainly in Western Vienna
Vienna’s inhabitants have reported about 300 foxes in the urban area to the internet platform www.stadtwildtiere.at [Link 13] during the last three months. These reports demonstrate that wild animals do not only live in remote woods, but more and more also in cities. Wildlife ecologist Theresa Walter from the Research Institute of Wildlife Ecology of the Vetmeduni Vienna investigated when and where in Vienna one is most likely to meet a fox. First analyses show that foxes are primarily seen at night in the western districts such as Hietzing and Penzing. The results were presented at the Annual Meeting of the Ecological Society in Göttingen on 2 and 3 September 2015.

The European Hare is a picky eater
In many children´s books one can find pictures of a hare in a cabbage patch. In reality, European hares have high nutritional requirements, which large-scale intensively farmed monoculture fields often cannot meet. Hares have a relatively high energy demand. Unlike small mammals they do not live in protective burrows or nests, which would help with body temperature regulation. Hare mothers give birth to precocious, rapidly growing young that are exposed to all kinds of weather conditions. Hare mothers feed their young with energy-rich high-fat maternal milk (containing more than 20% fat). For milk production the hare mothers therefore need sufficient body fat reserves. Polyunsaturated fatty acids (PUFA) seem to be especially important for reproduction and survival of the hares. In collaboration with the Institute of Wildlife Biology and Game Management of the University of Agricultural Sciences the researchers have now carried out a multiyear study in the agricultural landscapes of eastern Austria, which showed that hares prefer fatty plants and plant-parts all year round. Surprisingly the researchers did not find a preference for plants with a high PUFA content. An adequate supply of these essential components of the diet appears to be ensured by their specific extraction in the digestive tract. Overall, the results suggest that the promotion of heterogeneous cultural landscapes with high plant diversity and fallow land could counteract the Europe-wide decline in hare populations.
The article “The European Hare (Lepus europaeus): A Picky Herbivore Searching for Plant Parts Rich in Fat [Link 16]” by Stephanie Schai-Braun, Thomas Reichlin, Thomas Ruf, Erich Klansek, Frieda Tataruch, Walter Arnold and Klaus Hackländer appeared in July 2015 in the journal PLOS ONE [Link 17].

Wild boars are gaining ground – climate change boosts population growth
The wild boar population in Europe is growing. However, the reasons for this growth were not yet clear. Sebastian Vetter and other scientists from the Research Institute of Wildlife Ecology (FIWI) have now found out that climate change plays a major role. The number of wild boars grows particularly after mild winters. Food availability is also a decisive factor. There are more wild boars after years with high beechnut yield. Vetter and the research team at FIWI working with wild boars are going to continue their research in this field.
The article „What Is a Mild Winter? Regional Differences in Within-Species Responses to Climate Change [Link 20]" by Sebastian G. Vetter, Thomas Ruf, Claudia Bieber, and Walter Arnold was published in the Journal Plos One [Link ].
