The aim of the project is to survey hoverflies, together with bees the most important pollinators worldwide, nationwide. This will be the standardised monitoring data for these important headline indicators for the first time in Austria. In addition, the flowering plants visited by the hoverflies are to be plants visited by hoverflies in order to gain knowledge about the pollen and nectar sources of hoverflies. Data on the occurrence and distribution of highly endangered hoverfly species in Europe will also be collected. Overall, the project fills a gap in Austria's biodiversity monitoring, also collects data on species that are highly endangered throughout Europe, and thus represents an important contribution to achieving the goals set out in the national biodiversity strategy. It establishes the headline indicator hoverfly in Austrian biodiversity monitoring.

The von Bertalanffy equation was developed in the 1940s and has since been the almost universal biologically motivated model to describe the ontogenetic growth of different species; it is characterized by the metabolic exponents a = 2/3, b = 1. West et al. (1997, 2001) suggested another pair of metabolic exponents (a = 2/3, b = 1) and provided biological reasoning for this choice. This project proposes biological reasoning for yet two other exponent pairs based on the ideas of Bertalanffy and West about metabolism and on a model of Parks (1982) about the dependency of growth on food intake.

Since 2008 (with one year of interruption), fecal samples have been collected and genetically analyzed in the Gesäuse National Park at Gscheidegg and in neighboring areas to study capercaillie genetic diversity. The present project will process the samples from the last 3 years, thereby supplementing the dataset of this long-term monitoring effort, and conduct comprehensive analyses on the genetic diversity of the studied population. Particular focus will be placed on addressing potential significantly decreasing trends in this important biodiversity indicator.
