How the interplay of local adaptation and dispersal determines species appearance, distribution and range dynamics is still incompletely understood. Here we combine individual-based simulations and mathematical analysis of large-population approximation models to advance the analysis of spatial spread and phenotypic diversification of a...

Abstract Saturn's moon Enceladus is a top candidate in the search for extraterrestrial life in our solar system. Ecological thermodynamic modeling of the plume composition data collected by NASA's Cassini mission led to the hypothesis that a hydrogenotrophic methanogenic ecosystem might exist in the putative hydrothermal vents at Enceladus's...

During the Noachian, Mars' crust may have provided a favourable environment for microbial life1,2. The porous brine-saturated regolith3-5 would have created a physical space sheltered from ultraviolet and cosmic radiation and provided a solvent, whereas the below-ground temperature2 and diffusion6,7 of a dense, reduced atmosphere8,9 may have...
