Evolutionary persistence in Gunnera and the contribution of southern plant groups to the tropical Andes biodiversity hotspot

Editor rating: 9 / 10

Luis Eguiarte –– Gunnera is a genus of plants that have fascinated scientist for a long time, in particular for the very large leaves of some species and because its symbiotic relationship with the nitrogen fixing cyanobacteria Nostoc. For a many years, some botanists suspected it to be a very old, primitive genus, perhaps basal in the phylogeny of the Angiosperms. While latter molecular phylogenies did not support this position, this paper shows that indeed Gunnera is an old genus, with a complex evolutionary and phylogeographic history, and a recent radiation in the Andes. All these new results are relevant for understanding why the Neotropics have so many plant species, more than any other similar region in the planet.

A massive update of non-indigenous species records in Mediterranean marinas

Editor rating: 9 / 10

Mark Costello –– Due to the Suez Canal, the Mediterranean has more introduced species than any other sea area. However, there are often misidentifications and species suggested as "invasive" which are not (they may be rarely recorded but native). Thus a synthesis of this knowledge is timely and of wide international interest.
Neogene amphibians and reptiles (Caudata, Anura, Gekkota, Lacertilia, and Testudines) from the south of Western Siberia, Russia, and Northeastern Kazakhstan

Editor rating: 9 / 10

Graciela Piñeiro –– This manuscript is an important contribution to the knowledge of the almost unknown Siberian Neogene herpetofauna. It deals not solely with detailed anatomical descriptions and taxonomic identification of the specimens, but provides interesting paleobiogeographic hypotheses concerning the origin and dispersion of the taxa, including newly paleoclimatic and paleoenvironmental aspects spanning mostly the Oligocene to Pliocene periods. Studied environmental parameters include precipitation rates in the Miocene which are compared to current rainfall values for the region.
Deciphering the preservation of fossil insects: a case study from the Crato Member, Early Cretaceous of Brazil

Editor rating: 9 / 10

Graciela Piñeiro –– This is an important contribution for a better understanding of the taphonomic processes that allow the preservation of delicate organisms, and as so, it will be interesting to a wide readership.

Comparative internal anatomy of Staurozoa (Cnidaria), with functional and evolutionary inferences

Editor rating: 9 / 10

James Reimer –– A massive and detailed work which comparatively examines and summarizes the internal anatomy of the class Staurazoa for the first time, illustrated with an enormous set of figures. This manuscript will serve as a useful reference on this understudied group of animals for years to come.
Corallimorpharians are not “naked corals”: insights into relationships between Scleractinia and Corallimorpharia from phylogenomic analyses

Editor rating: 9 / 10

Mauricio Rodriguez-Lanetty –– This study presents novel phylogenomic data to assess the evolutionary relationships between scleractinians and corallimorpharians, and provides insights in the understanding of the evolution of calcification in the coral lineage.
