This study develops a method to assess phylogenetic networks and applies it to ostariophysan fishes, finding that a network with four reticulation events better explains their evolution than a tree-like topology.

The paper reports new fossil fish taxa from the Rio Acre locality in Brazil, showing ecological conservatism in Amazonian fish assemblages during the Neogene.

This study evaluates SNaQ's performance on non-level-1 phylogenetic networks and introduces new metrics to assess structural recovery.

The paper uses dual-hybridisation probes to reconstruct phylogenetic relationships in Sauvagesieae, finding evidence of polyploidisation and hybridisation affecting tree resolution.

This paper reports new fossil freshwater fish taxa from Pliocene formations in northern Colombia, suggesting historical connectivity between Amazon-Orinoco and trans-Andean drainages.

The paper reconstructs ancestral Gregorian chant melodies using Bayesian phylogenetics and compares results to historical methods.

The paper reassesses the taxonomic status of Farlowella colombiensis and finds it to be a junior synonym of Farlowella acus, providing a key and remarks on species in the F. acus group.

The paper examines the macroevolutionary patterns of dental morphology in Noctilionoid bats, identifying multiple diversification bursts linked to dietary specializations and adaptive regime shifts.

This paper introduces a Bayesian method to estimate stratigraphic intervals and their co-occurrence, using empirical examples and a Julia package for implementation.

The paper introduces the R package tbea to improve Bayesian divergence time estimation by integrating biological, geological, and palaeontological data for better model specification and reproducibility.

This study uses phylogenetic and biogeographic methods to examine how the closure of the Isthmus of Panama influenced the evolutionary history of Snooks.

This study uses morphometrics and phylogenomics to analyze coca species and their relatives, revealing gene flow and taxonomic implications for coca classification.
