Modelling exo-biospheres for biosignature predictions.. Searching for signs of alien life-biosignatures-on distant planets requires general hypotheses on the evolution of biospheres, and how life interacts with and influences its planet. We will not be able to visit a distant planet to directly observe any alien life and thus measuring properties of a biosphere such as organism abundance or reproduction rate is impossible. This paper provides an overview of two life-environment coupled models and analyses how their results might aid in guiding our search for biosignatures. The first model is of a simple methanogen biosphere and demonstrates that the 'strength' (i.e. the concentration of a g…
