Revision of the domestic cat study by Hackländer et al. 2014 and consideration of the latest scientific findings since publication. In addition, the situation in Germany will be addressed in particular. A special focus will be the question of hybridization between wild and domestic cats. For this purpose, current findings from master theses at BOKU on the space-time use of sympatric domestic and wild cats will be integrated in addition to the available literature. Evaluation of a survey in Schleswig-Holstein on hunters' experiences with domestic cats. Descriptive presentation of the results and written elaboration of the survey results, interpretation as well as conclusions regarding the importance of domestic cats for hunting.

In this project, the favorable reference population (= population in favorable conservation status) for the wolf in Germany is to be determined, taking into account various biological and anthropogenic factors demographic-genetic model calculations. On this basis, the required proportion in Lower Saxony is also to be calculated. Work package 1 - Literature research and evaluation 1.1 Brief compilation of established basic population biology assumptions and considerations for the survivability of networked (sub)populations of large carnivores such as wolves. 1.2 Evaluation of the sustainability study (Duchamp et al. 2017: Expertise collective scientifique sur la viabilité et le devenir de la population de loups en France à long terme) with regard to the applied methodology and a possible comparability of the basic population biological assumptions to the situation in Germany 1.3 Compilation of the data base on population size and population development of the wolf in Germany for work package 2, which is necessary for the own analysis Work package 2 - Analysis and evaluation 2.1 Development of demographic-genetic model calculations to determine the population size (MVP=Minimum Viable Population) necessary in Germany to minimize the extinction risk by applying population risk variables and considering different scenarios (PVA=Population Viability Analysis) 2.2 Selection of the most realistic model (sustainability analysis) 2.3 Determine an estimate of effective population size in terms of a favorable reference population above MVP to ensure long-term viability, taking into account uncertainty factors 2.4 Model-based estimation of the Lower Saxony portion as a subset of the favorable reference population Translated with (free version)

Reliable methods to estimate the size of a population are fundamental in wildlife management and conservation. This pilot study aims to delevop and test new approaches to estimate the population size of chamois (Rupicapra rupicapra) in national park Hohe Tauern Salzburg. The long-term objective is a reliable monitoring system enabeling to study the development of this population as well as changes in their temporal-spatial behaviour (f.e. to climate change).
