To reveal phylogeny of sparsely sequenced taxa, standard methods could not be successfully used due to patchy character of data and new methods had to be developed. We summarize such methods and present their funcionality on phylogeny of Arvicolini voles. Analyzing tree space with terraces, we have found that supermatrix approach is superior to supertree approach in extracting signal from data and determining a resolved and well-supported phylogeny. The most widely used program from Bayesian phylogeny inference fails to determine the correct lengths of branches in a large supermatrix with a lot of missing data, it still successfully determines the true tree topology.
