Short description of the thesis/topic:
Infection of the intestinal tract with an increasingly recognized number of bacterial pathogens can profoundly disrupt the intestinal function with or without causing overt dehydrating diarrhoea. In literature, there are many ways in which these organisms can cause diarrhoea, by diverse mechanism including enterotoxin/cytotoxin production, or mucosal adhesion to the small intestinal surface. There are many reasons why individuals differ in their susceptibility to infection with enteric pathogens, including their genetic makeup and their ability to mount potent immune responses in the gut. Therefore, the aim of the project is to identify possible alterations in the gut health in response to Campylobacter jejuni. Thus, the announced diploma thesis provides an excellent opportunity to be acquainted with techniques such as histopathology and real-time PCR.

Requirements:
Theoretical knowledge on nutrition and physiology

Further information:
PCR and classical histological techniques will be performed in this project

Kurzbeschreibung der Abschlussarbeit/des Themas:
In response to the EU ban on the use of antibiotics as growth promoters in animal feed, there is a growing interest in exploring natural alternatives assisting in maintaining a healthy rumen.The development of an effective feed additive in the favorable modification of ruminal fermentation may pave the way for the reduction of dependency on antibiotics. Sığla oil (sığla storax, Styrax liquidus) is a resinous exudate obtained from the wounded barks of the tree of Liquidambar orientalis. Because of its anti-bacterial and anti-nematode properties, it is thought that it may be an alternative to the prohibited antibiotics. Therefore, the aim of this project is to investigate the effects of two different doses of sığla oil on rumen microbiota and rumen microbial fermentation in comparison to an effective antibiotic, monensin, in the modification of ruminal fermentation using Rusitec (Rumen Simulation Techniquie).

Anforderungen/Erforderliche Kenntnisse:
An interest in ruminant nutrition and rumen health

An interest in learning Rumen simulation technique (Rusitec) and lab analytical methods

Knowledge of English (speaking and writing)

Short description of the thesis:

Intense research in the last few decades has shown that dogs are extremely good at reading human social and communicative behavior. However, as compared to social cognition, the cognitive abilities of dogs in the physical domain have been relatively sparsely studied. As a result, it still remains unclear what dogs know about physical relations, for instance about the fact that an object can have an impact on the movements of another one (i.e., means-end understanding).

A usual way of studying means-end understanding in animals is Piaget’s support problem”- which involves a goal object (e.g., food) that is out of a subject’s reach, but is resting on a support (e.g., a wooden board) that is within the subject’s reach. The task is based on the assumption that if an animal understands the physical properties of the wooden board it uses it as a means to an end, i.e., pulls the support to get the reward into reach. Animals without means-end understanding will only be able to succeed through repeated exposure allowing for associative learning.

In this study, dogs will be tested in a variation of the support problem – known as the “on/off task”. Dogs will need to retrieve an out-of-reach food reward placed behind a physical barrier (fence). While the reward itself is out of reach, it is physically connected to a wooden board within the dog’s reach. Dogs will be presented with two wooden boards - one board with a food reward on top of it (ON board), and another board with a reward placed next to it (OFF board). Successful retrieval of the treat requires the dogs to pull the appropriate board by pawing the wooden until the treat emerges from under the barrier.

Two groups of dogs will be tested repeatedly in two experimental conditions: 1) in the natural condition, dogs will be able to retrieve the reward by pulling the ON board. The reward placed next to the OFF board will not move if dogs pull on this board; 2) in the magic condition, dogs will be able to retrieve the reward by pulling the OFF board. The reward placed on the ON board will not move if dogs pull on this board. The main hypothesis is that, if solving the task is based on associative learning, dogs will learn the causally correct (i.e., natural) and causally incorrect (i.e., magic version) versions of the task similarly fast. However, if dogs have a certain level of means-end understanding, they will learn faster in the causally correct version than in the magic one.

Testing will take place in the Clever Dog Lab (link) and will be carried out by two master students who will collaborate to 1) conduct the behavioral testing, 2) conduct qualitative/quantitative behaviour coding (live and from videos), and 3) statistically analyse the data.

Requirements:

  • Experience with animal/dog handling
  • Basic knowledge in statistics using R
  • Excellent teamwork skills

 

Further information:

The students will learn how to design behavioral studies, conduct behavioral testing, conduct qualitative/quantitative behaviour coding (live and from videos), and statistically analyse data using the appropriate statistical methods.

The objective of the Diplomathesis is to compare different procedures of training dogs to engage with visual discrimination on the basis of classical and/or instrumental conditioning. The basic principle of autoshaping, which is a type of conditioning that occurs when an animal learns to respond to a stimulus without reinforcement, has proven highly efficient in pigeons. A brief illumination of a response button before the delivery of food results in the pigeon learning to peck the button whenever it is illuminated. However, in dogs this doesn’t work in the same manner. The reason is that for the pigeon the illuminated button serves as a substitute of the food reward, which elicits the natural foraging response, pecking. In dogs, the light does not serve as food substitute, and therefore the dog has to be “lured” or shaped to make a response to the stimulus. Subsequently the reinforcer is made contingent on the newly acquired response to the stimulus – touching the button is immediately reinforced with food – so bringing it under operant control. The aim of this diploma thesis is to compare different ways of “luring” or shaping the dog to make a response to the stimulus. A further goal is to compare dogs trained at dog schools and dogs trained at the Clever Dog Lab.

Requirements:
Experience in dog training (training dogs with positive reinforcement in line with the latest scientific findings and in accordance with animal welfare standards) is required. We expect the candidate to be familiar with basic statistics and to be able to fluently talk and write in English.

Further information:
Part of the work will be done at remote places in and around Vienna (dog schools), therefore having a car and a valid driving license is an advantage.

Dogs are not only able to identify humans (e.g. their caregiver) visually, but they are also able to discirminate emotional expressions of human faces (Müller et al., 2015, Current Biology). The aim of this diploma thesis is to test the hypothesis that dogs, like humans, need to add some positive emotions to a (protoypical) neutral face, i.e. the poser's facial muscles are relaxed (Ekman and Friesen, 1978), to be regarded as emotionally neutral (between positive and negative). We know that humans need to "add" about 25% of happiness in a face so that it is perceived as neutral (morphing studies, e.g. Phillips et al. 1997 Nature). Is it the same for dogs? We would train dogs to discriminate between two human faces, one with a positive, the other with a negative expression, and then intersperse in the generalization phase morphed faces between the end points, among them the intermediate face, i.e. the one that lies in the middle of the morph dimension between the training faces. This thesis would require visual discrimination training of dogs using the touchscreen apparatus. Dogs will be recruited from dog owners in Vienna and trained in the Clever Dog Lab.

Requirements:
Experience in dog training (training dogs with positive reinforcement in line with the latest scientific findings and in accordance with animal welfare standards) is required. We expect the candidate to be familiar with basic statistics and to be able to fluently talk and write in English.

Further information:
Advanced computer skills are an advantage (morphing).

Short description of the thesis/topic:
Our relationship with wolves and dogs extends back at least 30,000 years. While wolves are often feared, dogs have become a valued part of our lives. This perception appears to influence also our scientific discourse, where domestication hypotheses posit a shift in temperament from a more aggressive wolf to a gentler, friendlier dog. However, recent results of studies comparing similarly raised wolves and dogs suggest a more complicated picture. As part of a larger project including studies on humans, this PhD thesis will focus on two aspects: first, if a person’s attitude towards wolves and dogs affects his/her behavior towards them, eliciting specific reactions from the animals. Second, if the animals’ behaviors are in line with the hypersociability, the emotional reactivity or our own ‘deferential domestication hypothesis’. To investigate how our attitudes towards wolves and dogs influence the animal’s behaviours, we will observe the animal trainers and scientist as the Wolf Science Center in interactions with the animals and test the most prominent domestication hypotheses by comparing the human-directed behaviours of wolves and dogs raised and kept similarly, and pet dogs.

Requirements:
Eligible candidates will have a master’s degree (or Diplom) in Biology, Veterinary Medicine, Psychology, or related disciplines, research experience in animal behavior, a genuine understanding of animal cognition and a strong commitment to basic science. Practical skills in empirical work with dogs are beneficial, but not a precondition.

Short description of the thesis/topic:
Problem solving abilities are thought to be shaped by natural selection as a response to the species-specific challenges of their social-ecological environment. Dogs and wolves, diverged only relatively recently, but vary significantly in several factors of their social and ecological environments. They also show marked differences in their problem-solving abilities, with wolves often outperforming dogs. However, it is unclear whether this difference comes from their cognitive abilities (e.g. learning and inferential reasoning), motivation (e.g. persistence and neophobia) or general-purpose mechanisms (e.g. attention, working memory) and which selective pressures have shaped them. In the framework of the PhD, the student will test wolves and dogs that have had similar experiences throughout their lifetime as well as pet (and free-ranging dogs) in a series of paradigms measuring inferential reasoning skills including reasoning by exclusion, diagnostic and predictive inferences as well as their understanding of physical laws.

Eligible candidates will have a master’s degree (or Diplom) in Biology, Veterinary Medicine, Psychology, or related disciplines, research experience in animal behavior, a genuine understanding of animal cognition and a strong commitment to basic science.

Short description of the thesis/topic:
Learning from conspecifics can be one of the least expensive mechanisms to acquire information about the environment. But information provided by others can also be misleading, so animals employ specific strategies to decide when, what, and from whom to learn depending on the context. Free-ranging dogs live in a varied and fast-changing environment and are characterized by a complex social structure, thus providing a perfect model to investigate the environmental factors and social dynamics affecting the use of social learning. Moreover, thanks to the unique foraging style of free-ranging dogs, it is possible to explore the use of social learning across different foraging tasks. The project aims at investigating how social dynamics (e.g. relatedness, affiliation, dominance) affect the transmission of different types of information (varying in complexity). The project involves observational and non-invasive experimental work (e.g. open diffusion experiments) with free-ranging dogs in Morocco (Agadir area).

Project Description
Several Doctoral/PhD positions are open at the Christian-Doppler Christian-Doppler-Laboratory for Innovative Gut Health Concepts in Livestock (CDL-LiveGUT) located at the University of Veterinary Medicine in Vienna/Austria. In a nutshell, the aim of the research is to understand the molecular basis of rumen/gut microbiome × host interactions both driven from the animal individual characteristics and the diet. Upon this knowledge, feeding strategies will be tested to better exploit the such benefical interactions and enhance gastrointestinal health. The CDL-LiveGUT is joint research cluster that brings together various disciplines of animal nutrition, microbial ecology, gut physiology, and biomarker discovery, with a main goal to enhance gut health in farm animals by developing early biomarkers of gut health disorders and feeding approaches to prevent them.
