Fields of interest / focus of work
My multidisciplinary areas of research focus on the behavioural ecology, and molecular ecology of wild populations of birds. My research topics include (1) responses of individuals to changing environmental conditions, (2) foraging strategies, (3) reproductive strategies, (4) individual reproductive performance, and (5) the evolutionary consequences of behaviour. My research is conducted on wild populations of parrots, penguins, gulls and petrels since these offer excellent opportunities for testing a number of theoretical predictions. I initiated and lead several projects among them the ‘Breeding biology of Burrowing Parrots’ (since 1998). As a result, I have long-term data, for example on the breeding biology of Burrowing Parrots, which allow me to tackle a number of topical research questions. During my research, I gained expertise in a wide variety of skills e.g., genomics, population genetics, calculation of energy landscapes for the study of foraging behaviour, analysis of acceleration data using machine learning in R for the investigation of animal behaviour, molecular analysis of the diet including bioinformatics in GALAXY, metabarcoding, GIS (QGIS and ArcGIS), use of time-depth, GPS, accelerometer and compass loggers, molecular sexing, reflectance spectrometry, audio and video recordings of behaviour, field immunology (analysis of blood smears), supplementary feeding, analysis of ectoparasites, bird ringing, rock climbing, aerial and terrestrial surveys. A further focus of my work is to contribute scientific data to enable more effective conservation of species and ecosystems. Since 2003, I am involved in projects on parrot conservation in co-operation with the Wildlife Conservation Society, the World Parrot Trust, and Aves Argentinas among others.
