Repeatability of glucocorticoid hormones in vertebrates: a meta-analysis

Editor rating: 7 / 10

Dany Garant –– Nice overview of published literature on the topic.
A new slider turtle (Testudines: Emydidae: Deirochelyinae: Trachemys) from the late Hemphillian (late Miocene/early Pliocene) of eastern Tennessee and the evolution of the deirochelyines

Editor rating: 7 / 10

Andrew Farke –– Describes a new fossil species from a group of turtles that are ecologically important in North America today.
A simple molecular technique for distinguishing species reveals frequent misidentification of Hawaiian corals in the genus Pocillopora

Editor rating: 8 / 10

Xavier Pochon –– This study developed a simple and cost-effective assay that quickly allows for discrimination amongst coral species in the genus Pocillopora using simple PCR amplification followed by digestion with widely available restriction enzymes. Pocilloporid corals exhibit extreme phenotypic plasticity, making morphological identification of species very challenging. The assay was tested on 691 coral samples collected from across the Hawaiian Archipelago and successfully characterised all six Pocillopora species occurring in Hawaii. Compared to sequence-based identification, this method is simple, rapid and represents a cost saving of nearly 95%. This work will benefit future studies of population structure, ecology, biodiversity, evolution and conservation in this challenging coral genus.
Differential gene expression during early development in recently evolved and sympatric Arctic charr morphs

Editor rating: 7 / 10

Marc Robinson-Rechavi –– This study allows to link natural variation in morphology with genetic divergence in expression patterns, thus helping link ecology to molecular genomics.
Evaluating the adaptive evolutionary convergence of carnivorous plant taxa through functional genomics

Editor rating: 8 / 10

Todd Vision –– This is a novel and innovative approach to studying the genomic correlates of convergent evolution. It is likely to inspire similar studies in other systems and for other kinds of genomic changes, as well as bioinformatic work to refine and extend the methods.
The oldest Archaeopteryx (Theropoda: Avialiae): a new specimen from the Kimmeridgian/Tithonian boundary of Schamhaupten, Bavaria

Editor rating: 7 / 10

Mark Young –– This manuscript is an excellent, thorough description of a new specimen of the iconic early bird Archaeopteryx.
Molecular phylogenetics of swimming crabs (Portunoidea Rafinesque, 1815) supports a revised family-level classification and suggests a single derived origin of symbiotic taxa

Editor rating: 9 / 10

Mohammad Shamsur Rahman –– very much fantastic work in the field of taxonomy, both in classical and molecular approach!
The old and the new plankton: ecological replacement of associations of mollusc plankton and giant filter feeders after the Cretaceous?

Editor rating: 7 / 10

Kenneth De Baets –– The manuscript reviews the potential replacement of associations of mollusc plankton and giant filter feeders from the Mesozoic to the modern. It will therefore be of interest to biologists, ecologists and paleontologists.
Simulations indicate that scores of lionfish (Pterois volitans) colonized the Atlantic Ocean

Editor rating: 7 / 10

Mark Hixon –– This study provides insight on the size of the founding introduced population that gave rise to one of the worst marine invasions in history.
The shell morphology of the latest Cretaceous (Maastrichtian) trionychid turtle Helopanoplia distincta

Editor rating: 7 / 10

Christopher Noto –– This article describes an important but poorly-diagnosed taxon of pan-trionychid turtle that will have an impact on understanding the phylogeny of plastomenids, as well as address issues of extinction across the K-Pg boundary, and biogeography of Laramidia.
