Maximum likelihood of phylogenetic networks [PDF]
Bioinformatics, 2006 Abstract Motivation: Horizontal gene transfer (HGT) is believed to be ubiquitous among bacteria, and plays a major role in their genome diversification as well as their ability to develop resistance to antibiotics. In light of its evolutionary significance and implications for human health, developing accurate and efficient methods for ...

A network perspective on the topological importance of enzymes and their phylogenetic conservation
BMC Bioinformatics, 2007 Background A metabolic network is the sum of all chemical transformations or reactions in the cell, with the metabolites being interconnected by enzyme-catalyzed reactions. Many enzymes exist in numerous species while others occur only in a few.

Restricted trees: simplifying networks with bottlenecks [PDF]
, 2010 Suppose N is a phylogenetic network indicating a complicated relationship among individuals and taxa. Often of interest is a much simpler network, for example, a species tree T, that summarizes the most fundamental relationships. The meaning of a species

Peer Community Journal, 2022 Whether interactions between species are conserved on evolutionary time-scales has spurred the development of both correlative and process-based approaches for testing phylogenetic signal in interspecific interactions: do closely related species interact

A new measure of dissimilarity and fuzzy linear programming model to construct phylogenetic network among DNA sequences [PDF]
Network Biology, 2019 The growth of DNA databases used to store large number of biological sequence data, has stimulated the importance of alignment of sequences for phylogenetics.

BMC Bioinformatics, 2005 Background Phylogenetic approaches are commonly used to predict which amino acid residues are critical to the function of a given protein. However, such approaches display inherent limitations, such as the requirement for identification of multiple ...

A Phylogenetic Networks perspective on reticulate human evolution
iScience, 2021 SUMMARY: We present a methodological phylogenetic reconstruction approach combining Maximum Parsimony and Phylogenetic Networks methods for the study of human evolution applied to phenotypic craniodental characters of 22 hominin species.

A first step towards computing all hybridization networks for two rooted binary phylogenetic trees
, 2011 Recently, considerable effort has been put into developing fast algorithms to reconstruct a rooted phylogenetic network that explains two rooted phylogenetic trees and has a minimum number of hybridization vertices.

Leaf-Reconstructibility of Phylogenetic Networks [PDF]
SIAM Journal on Discrete Mathematics, 2018 An important problem in evolutionary biology is to reconstruct the evolutionary history of a set $X$ of species. This history is often represented as a phylogenetic network, that is, a connected graph with leaves labelled by elements in $X$ (for example, an evolutionary tree), which is usually also binary, i.e. all vertices have degree 1 or 3. A common
