1. Sex, Molecules, and Gene control : Ecophysiological and evolutionary aspects of key sponge species from Antarctic shallow waters and the deep sea
Abstract : Very little is known about the ecophysiological aspects of Porifera (sponges) from Antarctica and North Atlantic, even though they are keystone components of these habitats. Being the earliest diverging metazoan lineage, sponges also play a fundamental role in our understanding of animal evolution. READ MORE

2. The evolution of respiratory chain complex I from smaller functional modules
Abstract : NADH:quinone oxidoreductase, or complex I, is a large membrane bound enzyme in the respiratory chain of living organisms, that has evolved from the combination of smaller functional building blocks. The enzyme has a conserved core structure, comprising 14 protein subunits: Seven subunits protrude from the membrane and contain a flavin and eight iron-sulfur clusters. READ MORE

3. Reversible modifications of chloroplast proteins and assessment of their functions
Abstract : Oxygenic photosynthesis is the process of solar energy conversion into chemical energy in the form of carbohydrates. This event is carried out by plants, algae and cyanobacteria and represents the starting point of the food chain in which most organisms are fed. READ MORE

4. Pathways to future cropland : Assessing uncertainties in socio-economic processes by applying a global land-use model
Abstract : Global agricultural production almost tripled within the last five decades. The production increase wasbased on expanding cropland and pastures, as well as the intensification of agriculture, including increased use ofhigh yielding crop varieties, machinery, irrigation, artificial fertilisers, and pesticides.

5. Modelling site-dependent environmental impacts of nitrogen fertiliser use in life cycle assessments of crop cultivation
Abstract : Use of mineral nitrogen fertilisers in crop cultivation has enabled substantial yield increases, strengthening global food security. High yields also allow better resource efficiency and result in higher organic matter inputs to soil, increasing the potential for soil carbon sequestration. READ MORE
