1. Evolutionary Approaches to Sequence Alignment
Abstract : Molecular evolutionary biology allows us to look into the past by analyzing sequences of amino acids or nucleotides. These analyses can be very complex, often involving advanced statistical models of sequence evolution to construct phylogenetic trees, study the patterns of natural selection and perform a number of other evolutionary studies.

2. Understanding evolutionary novelty through female-limited polymorphisms
Abstract : Understanding how novel traits evolve is a central question in evolutionary biology. However, unraveling the complex genetic and developmental mechanisms underlying trait innovation can be challenging, especially when the trait evolved a long time ago. READ MORE

3. The Industrial TransformationTowards the Circular Economy : Dynamics, Drivers and Constraints
Abstract : The notion of the circular economy has recently been posited as a vital strategy to mitigate climate change. At the industrial level, the circular economy envisions socio-industrial transformation to closed-loop material systems. READ MORE

4. On the Evolution of the Avian Transcriptome
Abstract : Change in gene expression is a powerful tool for evolution, because seemingly small expression changes can contribute important steps towards adaptation without necessarily affecting the whole organism. There is still much to learn about how gene expression evolves on genome- and population-wide levels, especially in non-model organisms. READ MORE

5. Thinking in water : Brain size evolution in Cichlidae and Syngnathidae
Abstract : Brain size varies greatly among vertebrates. It has been proposed that the diversity of brain size is produced and maintained through a balance of adaptations to different types and levels of cognitive ability and constraints for adaptive evolution. READ MORE
