1. Olfaction in Desert Locusts- Anatomy, Function and Plasticity of the Central Olfactory System
Abstract : The anatomy, function and plasticity of the primary olfactory centre, the antennal lobe (AL), of the desert locust Schistocerca gregaria was investigated using a number of neuroanatomical and neurophysiological methods. Anatomical characterisation of the AL in a number of orthopteran species made it possible to deduce a model concerning the evolution of microglomeruli. READ MORE

2. Thyroid hormone receptors and the regulation of bone physiology
Abstract : The aim of the studies in this thesis was to investigate the role of thyroid hormone receptors in bone physiology. Thyroid hormone signals through its receptors, the TRs, and has profound effects on bone development and metabolism, as demonstrated in hypo- and hyperthyroidism. READ MORE

3. Unraveling the regulatory mechanisms of pupal diapause termination
Abstract : Diapause is an essential part of many insect’s life cycle and is a developmental halt induced by environmental cues in advance of deteriorating conditions. Insects typically enter diapause to avoid unfavorable environmental conditions like low temperatures, poor food quality and the absence of conspecifics. READ MORE

4. Ontogenetic Characterization of Müllerian Duct Development and Expression of anti-Müllerian hormone and Other Genes : New Endpoints in the Frog Xenopus tropicalis Test System
Abstract : The amphibian model-species Xenopus tropicalis is used in reproductive toxicology studies. Lifecycle studies are requested but they are time consuming and susceptible to several of the risks attributed to long-term studies. READ MORE

5. From environmental cue to phenotypic variation – a functional investigation of wing polyphenism in an emerging model species
Abstract : Phenotypic plasticity is a ubiquitous feature of living organisms and enable individuals to adapt to changing environments. A particularly prominent example of plasticity is found in polyphenisms, where environmental cues received during development leads to the generation of discrete variation in populations. READ MORE
