Resumen:
Understanding patterns and processes in biological diversity is a
critical task given current and rapid environmental change. Such
knowledge is even more essential when the taxa under consideration are
important ecological and evolutionary models. One of these cases is the
monogonont rotifer cryptic species complex Brachionus plicatilis, which
is by far the most extensively studied group of rotifers, is widely used
in aquaculture, and is known to host a large amount of unresolved
diversity. Here we collate a dataset of previously available and newly
generated sequences of COI and ITS1 for 1273 isolates of the B.
plicatilis complex and apply three approaches in DNA taxonomy (i.e.
ABGD, PTP, and GMYC) to identify and provide support for the existence
of 15 species within the complex. We used these results to explore
phylogenetic signal in morphometric and ecological traits, and to
understand correlation among the traits using phylogenetic comparative
models. Our results support niche conservatism for some traits (e.g.
body length) and phylogenetic plasticity for others (e.g. genome size).
