Evolutionary relationships between species are usually represented in phylogenies, i.e. evolutionary trees, which are a type of networks. The terminal nodes of these trees represent species, which are made of individuals and populations among which gene flow occurs. This flow can also be represented as a network. In this paper we briefly show some properties of these complex networks of evoluti...

Every year, many tonnes of Posidonia oceanica are removed from Mediterranean beaches to maintain the quality and pleasure use beaches. Most this waste ends up in landfills, entailing removal costs. In work, material was characterised, a washing system developed obtain biochar. An adequate starting biomass shown play key role as it led an over 90% salt content reduction and, therefore, decrease ...
