Data from: Do the historical biogeography and evolutionary history of the digenean Margotrema spp. across central Mexico mirror those of their freshwater fish hosts (Goodeinae)?

Andrés Martínez-Aquino, Fadia Sara Ceccarelli, Luis E. Eguiarte, Ella Vázquez-Domínguez & Gerardo Pérez-Ponce De León
Host-parasite systems provide an ideal platform to study evolution at different levels, including codivergence in a historical biogeography context. In this study we aim to describe biogeographic and codivergent patterns and associated processes of the Goodeinae freshwater fish and their digenean parasite (Margotrema spp.) over the last 6.5 Ma (million years), identifying the main factors (host and/or hydrogeomorphology) that influenced the evolution of Margotrema. We obtained a species tree for Margotrema spp. using DNA sequence...

Data from: Calculating structural complexity in phylogenies using ancestral ontologies

Martín J. Ramírez & Peter Michalik
Complexity is an important aspect of evolutionary biology, but there are many reasonable concepts of complexity, and its objective measurement is an elusive matter. Here we develop a simple measure of complexity based on counts of elements, incorporating the hierarchical information as represented in anatomical ontologies. Neomorphic and transformational characters are used to identify novelties and individuated morphological regions, respectively. By linking the characters to terms in an anatomical ontology a node-driven approach is implemented,...

Data from: Description and phylogenetic position of a new species of Oreobates (Anura: Craugastoridae) from northwestern Argentina

Martín O. Pereyra, Darío E. Cardozo, Jorge Baldo & Diego Baldo
We describe a new species of Oreobates from Jujuy, Argentina. The new species is clearly diagnosable from other species of Oreobates by a combination of morphological characters and supported by molecular evidence (genetic distance and phylogenetic analysis). We also provide taxonomic comments about O. discoidalis and O. barituensis, emphasizing the need for an exhaustive revision of these species
