The raccoon and the raccoon dog are two non-indigenous animal species that have become established in Europe in the past decades. Their increasing abundance has not only made them the most common carnivore species in some countries, but has also made them of interest to parasitologists as potential hosts for diseases. A team of researchers from Vetmeduni Vienna has now analysed samples from both species in Austria. The raccoon dog, which is more closely related to the fox, was shown to serve as an additional host for local parasites. Like the fox, it represents a risk as a host of zoonotic parasites, such as the fox tapeworm or trichina worms, that are also of relevance for humans. The raccoons sampled, as they mainly originated from fur farms, were still largely pathogen-free. The article "The raccoon dog (Nyctereutes procyonoides) and the raccoon (Procyon lotor)—their role and impact of maintaining and transmitting zoonotic diseases in Austria, Central Europe [Link 3]" by researchers at the Institute of Parasitology, the Research Institute of Wildlife Ecology, and at AGES was published in the journal Parasitology Research.

Protected areas and connected natural axes - landscapes that wildlife can cross - form the basis of an Alpine “ecological network” for the protection of habitat and biodiversity. Such regional nature networks are now receiving additional support through the ALPBIONET 2030 project, which is funded by the European Union´s Alpine Space Programme. In various work packages, conditions for the implementation of ecological connectivity measures and national biodiversity strategies throughout the Alpine region will be improved. The Conservation Medicine Unit of the Research Institute of Wildlife Ecology, Vetmeduni Vienna, is responsible for the management of a work package for the analysis and improvement of Alpine wildlife management strategies, as well as the development of standardized forensic methods, which will be helpful for combating wildlife crime.

A new project financed by the Austrian Science Fund FWF was recently launched on the topic of "Polyunsaturated fatty acids and seasonal acclimatization [Link 9]".   Profound changes of metabolic rate and body temperature seem to be ubiquitous among birds and mammals living in seasonal environments, as is associated membrane remodelling. However, specific effects of polyunsaturated fatty acids (PUFA) in phospholipids suggest trade-offs determining seasonal changes of the fatty acid composition of membranes that are largely independent of direct dietary intake.   The current project investigates in detail effects of PUFA on seasonal acclimatization in red deer. 

The project´s principal investigator is Univ.Prof. Dr. Walter Arnold, Head of the Research Institute of Wildlife Ecology.

A new research project financed by the Austrian Research Promotion Agency (FFG) is intended to improve understanding of the population dynamics of wild boars in times of climate change. The project "Wildlife Management in Climate Change: Studies on Thermoregulation in Wild Boars [Link 11]" examines how the body temperature of wild boars changes throughout the annual cycle. It also analyzes how extreme heat periods or cold spells affect body temperature. The effect of the energy budget on survival and reproduction will also be recorded. At the same time, the researchers are observing behavioral changes and activity patterns of wild boars under various climatic conditions. The long-term objective is to use the results obtained from this basic research as a basis for the development of new wildlife management strategies.

The project is led by Dr. Claudia Bieber from the Research Institute of Wildlife Ecology.

Tail hairs reveal dietary choices of three horse species in the Gobi Desert

If you know how fast the hairs grow, you can date specific hair segments and clearly assign them to a certain season. Consecutive hair segments therefore provide valuable information about the diet and water balance of an individual animal. (Photo P. Kaczensky)

Przewalski’s horses, a species of wild horse that has been successfully reintroduced to the Gobi Desert, share their pasture grounds with wild asses and free-roaming domestic horses. A scarce supply of food could lead to food competition among the different species, especially if they make the same dietary choices. A team led by Martina Burnik Šturm and other researchers from the Research Institute of Wildlife Ecology of the Vetmeduni Vienna therefore chemically analysed the tail hairs of the animals to determine the seasonal dietary habits of the three species. While the wild ass switches from being a grazer in the summer to also browse in the winter, the wild and domestic horses eat exclusively grass all year round. In the lean winter months, this leads to increased food competition between wild and domestic horses. This realisation could help improve wildlife management measures for the Przewalski’s horse in the future.

The chemical analysis used by Burnik Šturm and Kaczensky measures so-called stable isotopes in the tail hairs. Stable isotopes are atoms of of the same chemical element with the same number of protons but different number of neutrons and thus with different masses. The isotope values in the body tissue of living organisms are the result of the isotope values in the environment and of the animal’s metabolism. An exact understanding of the dietary behaviour of the Przewalski’s horse and the khulan are important for improving the conditions in the protected area.

The article "Sequential stable isotope analysis reveals differences in dietary history of three sympatric equid species in the Mongolian Gobi [Link 17]" by Martina Burnik Šturm, Oyunsaikhan Ganbaatar, Christian C. Voigt, and Petra Kaczensky was published in the Journal of Applied Ecology.

Water availability as a key driver of khulan mobility in the Gobi

 [Link 19]
 [Link 20]

In resource-poor environments many large herbivores do not perform seasonal migrations but show unpredictable, year round long-range movements. The few studies that have examined drivers of long-range movements suggest that they are a response to volatile dynamics of foraging resources.  Asiatic wild asses (khulan) in the Mongolian Gobi are highly mobile, traveling large distances to find forage and water.  Led by Dejid Nandintsetseg , a group of Mongolian and international scientists, including Petra Kaczensky of the Research Institute of Wildlife Ecology, used six years of ground census data (see Figure 1) and time-matched remotely sensed imagery of vegetation productivity to build habitat models.  Although they found that vegetation productivity was an important predictor of khulan presence, it actually varied little within and among years, thus making it an unlikely driver for the large scale movements of khulan in this region. However, the model also showed that khulan avoid habitats that are further than 21 km from water sources and together with additional telemetry data the results suggest that water availability and switching among the sparsely located water bodies may be the key driver for the high mobility of khulan in the Dzungarian Gobi.

A key finding of relevance for policy makers and conservationists is the need to ensure functional connectivity among water bodies in dryland ecosystems.  Further studies are needed to identify and understand the full range of possible drivers of nomadic wildlife movements in drylands as a basis to maintain long-term landscape connectivity in a changing world.

Edible Dormice: The older they get, the more they rejuvenate their cells

In normal somatic cells, telomeres are shortened with every cell division. Besides, oxidative stress has a strong effect on telomere erosion. However, the rate of telomere shortening differs between species. For instance, it has been shown before that telomeres in fast-aging, short-lived wild animals erode more rapidly than in slow-aging, long-lived species.  The shortening of telomeres in cells was thought to be an important biomarker for lifespan and aging. The edible dormouse (Glis glis), a small hibernating rodent, now turns everything upside down. In contrast to humans and other animals, telomere length in the edible dormouse significantly increases in the second half of its life, as Franz Hoelzl and other researchers from the Research Institute of Wildlife Ecology and the Konrad Lorenz Institute of Ethology of the Vetmeduni Vienna found out just recently.

The article "Telomeres are elongated in older individuals in a hibernating rodent, the edible dormouse (Glis glis) [Link 23]" by Franz Hoelzl, Steve Smith, Jessica S. Cornils, Denise Aydinonat, Claudia Bieber, and Thomas Ruf was published in Scientific Reports (Nature Publishing Group).

 [Link 26]

Mongolia's Gobi Desert ecosystem is a stronghold for populations of the Asiatic wild ass (khulan) and the goitered gazelle, but it faces conservation challenges as a result of rapid economic development, including mining-related infrastructure projects.  Data on population sizes for these ungulates are scarce.  Over the past several years Mongolian and international researchers, among them Petra Kaczensky from the Research Institute of Wildlife Ecology, undertook a survey of these species over an area of almost 79.000 km2.  Under the lead of B. Buuveibaatara  the scientists´ findings confirm that the Gobi Desert supports the largest populations of khulan and goitered gazelles in the world.  Their research also suggests that in areas of greater human presence or activity, ungulate presence declines.  Based on habitat models, which the scientists built for both species, they found that human-associated factors are more important than environmental variables in explaining the distribution of the two species.  These findings were corroborated by telemetry data of marked individuals.  The scientists´ findings are highly relevant for policy makers, managers, and industry to plan mitigation measures helping to reduce the impacts of the human footprint on Mongolian wildlife.

The article Human activities negatively impact distribution of ungulates in the Mongolian Gobi [Link 27] by B. Buuveibaatara, T. Mueller, S. Strindberg, P. Leimgruber, P. Kaczensky, and T.K. Fuller was published in the journal Biological Conservation in November 2016.

By the mid-1970s the Saker falcon (Falco cherrug) was considered as almost extinct in Austria.  However, over the past few years that has been a strong positive population development trend, partly thanks to the mounting of nesting aids on powerline masts. This has been documented since 2010 by Dr. Richard Zink from the Research Institute for Wildlife Ecology of Vetmeduni Vienna and BirdLife Austria. The project is supported by Austrian Power Grid AG, which finances it and enables the mounting of nesting aids on its network.

The breeding season 2016 constitutes a record for the Saker falcon in every respect and continues the success story of the conservation of these rare birds of prey. 36 breeding pairs reared 64 young birds, 12 young falcons more than in the previous year. Despite this notable upward trend the Saker falcon still belongs to the list of endangered birds of prey in Austria.

Closing the data gap on stable isotopes in precipitation in the Mongolian desert

Stable isotopes (atoms of the same element with the same number of protons but different number of neutrons in the nucleus, and thus with different masses) are powerful forensic recorders that can be linked to large scale patterns in the landscape. Over the last decade, global hydrogen and oxygen isotopic patterns of precipitation have increasingly been used in studies on animal migration, forensics, food authentication and traceability studies. However, records of the stable isotope composition of precipitation spanning one or more years are available for only a few hundred locations worldwide.

Data for Mongolia are especially scarce;  there were none at all for the Dzungarian Gobi until Martina Burnik Šturm and Petra Kaczensky from the Research Institute of Wildlife Ecology and colleagues were able to close this gap by providing the first field-based data for this extremely arid environment on the hydrogen and oxygen isotope values of precipitation, as well as for rivers and various other water bodies.

High food availability slows down cell aging in edible dormice

The research team analyzed DNA and hence the length of the telomeres in saliva of the dormouse to describe the cell age. The so called arousals increase the cell aging of the dormouse. High food availability during the active phase not only compensates this effect, it also rejuvenates the cells. (Photo: Vetmeduni Vienna)
Young edible dormice in nest box [Link 52]

Hibernation has long been considered the secret behind the relatively long lifespan of the edible dormouse. However, a team of researchers from the Research Institute of Wildlife Ecology (FIWI) has now shown for the first time that high food availability during the active season in summer contributes to a long life. Increased food availability during this time allows the animals to slow their cellular aging. The study was published in the Journal of Experimental Biology.

“Telomeres get shorter with every cell division and are therefore considered a biological marker of ageing”, explains Franz Hoelzl from Vetmeduni Vienna’s FIWI. Telomeres form protective caps at the ends of the chromosomes to prevent genomic degradation. When the telomeres become too short, cell division is no longer possible and the cell looses the potential to divide and dies. It had previously been assumed that the slow-down of body functions during hibernation was responsible for decreasing the rate of telomere degradation. The edible dormouse’s long torpor-phases would thus contribute to its high life expectancy.

The article „Telomere dynamics in free-living edible dormice (Glis glis): the impact of hibernation and food supply [Link 53]“ by Franz Hölzl, Jessica S. Cornils, Steve Smith, Yoshan Moodley and Thomas Ruf was published in the Journal of Experimental Biology.
