A honey bee colony (Apis mellifera) consists of several thousand individuals, the majority of which are worker bees. Worker bees are responsible for important tasks in the colony (cleaning, brood rearing, foraging, etc.). For this purpose, worker bees have an enormous behavioural spectrum and great behavioural plasticity.
For example, a honey bee colony is able to regulate the climatic conditions in the hive very precisely. They can produce heat or actively contribute to cooling. On the one hand, this is necessary because the honey bee brood is very sensitive to the slightest fluctuations. On the other hand, honey bees are able to live in very different climatic zones or actively survive cold winters.
Our research focuses on the molecular and physiological mechanisms that enable certain behaviours and their plasticity in the first place. A particular focus is on the aminergic system. The methods we combine in our investigations cover a wide range of different fields, with molecular biology, neurochemical analysis and behavioural pharmacology being of particular importance.
