The taxonomy of cyanobacteria has been substantially modified in the last few decades, particularly after application of modern ultra structural and molecular methods. The present research, therefore, aimed to investigate, through a polyphasic approach, the differences in morphological and genotypic features of two cyanobacteria strains isolated from different agricultural and freshwaters areas...
s of posters • Krzysztof Bartoszek (Chalmers U., Gothenburg) Conditioned branching processes and phenotype evolution Abstract. Conditioned branching processes have recently received a lot of attention in the biomathematical literature. They are useful for modelling and developing software in the field of phylogenetic tree inference. However on top of this they can also be combined with continuo...
We propose a novel machine learning algorithm for learning mutation pathways of viruses from a population of viral DNA strands. More specifically, given a number of sequences, the algorithm constructs a phylogenetic tree that expresses the ancestry of the sequences, and at the same time builds a model describing dependencies between mutations that is consistent with the data as well as the phyl...
Delimiting species and clarifying phylogenetic relationships are the main goals of systematics. For species with questionable taxonomic status, species delimitation approaches using multi-species coalescent models with multiple loci are recommended if morphological data are unavailable or unhelpful. Moreover, these methods will also reduce subjectivity based on genetic distance or requirement o...
