1. Micro- and macroevolutionary aspects of body size diversification and thermal adaptation in insects
Abstract : Body size and body temperature are the two most important traits in biology. In this thesis I show how these twovariables have shaped the evolution of insects over the last 300 million years. READ MORE

2. Ontogeny and Population Biology of a Sex-Limited Colour Polymorphism
Abstract : This study has involved investigation of number of populations of the damselfly Ischnura elegans over several years, looking at frequency changes over time, morphological differences between the sexes and the morphs, differences in growth rate and development time, differences in fecundity between the morphs, and genetic differentiation between populations. I. READ MORE

3. Sub-lethal Effects of Anthropogenic Contaminants on Aquatic Invertebrates
Abstract : Anthropogenic contaminants are considered to play a substantial role in the decline of freshwater invertebrate diversity. Sub-lethal effects of many of these contaminants on behaviour and life-history traits of aquatic invertebrates may contribute to their decline. READ MORE

4. The effects of exposure to microplastics and pollutants on the arthropod microbiome
Abstract : Anthropogenic pollution is widespread across various ecosystems. This disturbance can alter the interaction between a host and its associated microbiome, with repercussions for hosts traits such as health, behavior, and host evolution. READ MORE

5. Thermal adaptation along a latitudinal gradient in damselflies
Abstract : Understanding how temperature affects biological systems is a central question in ecology and evolutionary biology. Anthropogenic climate change adds urgency to this topic, as the demise or success of species under climate change is expected to depend on how temperature affects important aspects of organismal performance, such as growth, development, survival and reproduction.
