Bony fish genomes: Status and gaps

Journal of Fish Biology, EarlyView.
Abstract Bony fish constitute an exceptionally species‐rich group of aquatic vertebrates, comprising more than 95% of all living fish. The adaptive processes on the diversity of environments they inhabit make them a highly diverse group from taxonomic, morphological and evolutionary standpoints.

A new sexually dimorphic species of the armoured catfish genus Neoplecostomus (Siluriformes: Loricariidae) from Neotropical Atlantic coastal drainages

Journal of Fish Biology, EarlyView.
Abstract A new species of the small‐sized armoured catfish genus Neoplecostomus is described from Neotropical Atlantic coastal drainages, in southeast Brazil. The new species can be readily diagnosed from all congeners by having the first plates of the ventral series reduced in size, rounded and ventrally displaced, resulting in a naked band between ...

Cryptic diversity and recent diversification in the Pyrrhulina australis species complex (Characiformes, Lebiasinidae) revealed by mitochondrial DNA

Journal of Fish Biology, EarlyView.
Abstract Pyrrhulina australis Eigenmann & Kennedy, 1903, is widely distributed across the main hydrographic basins of South America. The taxonomic integrity of this species is nevertheless challenged by the lack of clear diagnostic characters, its marked geographic variation and the morphological overlap with its congeners. In this context, the present

Phylogenomics of the American robin (Turdus migratorius) reveals hidden lineages and introgression

Journal of Systematics and Evolution, EarlyView.
Phylogenomic analyses of Turdus migratorius uncover four previously unrecognized lineages, including a divergent Baja California lineage (T. m. confinis). The results reveal complex evolutionary relationships that depart from simple models of continuous divergence, supported by evidence of introgression between the Mexican lineage and its previously ...

Going silent? Evidence for independent losses of acoustic communication in tree crickets (Insecta, Orthoptera, Grylloidea, Oecanthidae)

Journal of Systematics and Evolution, EarlyView.
Our ancestral state reconstruction in tree crickets reveals multiple independent and irreversible losses of sound‐producing and ‐receiving structures, supporting the convergent evolution of the silent phenotype. We demonstrate strong evolutionary integration between forewings and tympana, although the discovery of ‘silent listeners′ and ‘deaf singers ...
