  The phylogenetic network emerged in the 1990s as a new model to represent the
evolution of species in the case where coexisting species transfer genetic
information through hybridization, recombination, lateral gene transfer, etc.
As is true for many rapidly evolving fields, there is considerable
fragmentation and diversity in methodologies, standards and vocabulary in
phylogenetic network research, thus creating the need for an integrated
database of articles, authors, techniques, keywords and software. We describe
such a database, "Who is Who in Phylogenetic Networks", available at
http://phylnet.univ-mlv.fr. "Who is Who in Phylogenetic Networks" comprises
more than 600 publications and 500 authors interlinked with a rich set of more
than 200 keywords related to phylogenetic networks. The database is integrated
with web-based tools to visualize authorship and collaboration networks and
analyze these networks using common graph and social network metrics such as
centrality (betweenness, eigenvector, degree and closeness) and clustering. We
provide downloads of raw information about entries in the database, and a
facility to suggest modifications and contribute new information to the
database. We also present in this article common use cases of the database and
identify trends in the research on phylogenetic networks using the information
in the database and textual analysis.
