  Evaluation Summary:

  This paper will be of interest to evolutionary biologists and geneticists, particularly those interested in the evolution of sex determination and sexual conflicts. It provides an unprecedented dataset that enables the authors to show convincingly the presence of three different Y-chromosomes segregating within a species, differential presence of the Ys among ecomorphs, and identifies candidate sex determination genes on the different Ys. Examination of the impact of genetic sex on a male fitness proxy in ecological context provides a compelling case study to explain the stable maintenance of multiple genetic sex determination systems in a species.

  Evaluation Summary:

  Baker et al. investigates the molecular evolution in primates of one protein family, the CEACAMs, that are a recurrent target of bacterial surface adhesions at epithelial surfaces. They show that multiple members of this gene family have experienced repeated episodes of positive selection in primates, especially in the N-terminal domains that are associated with protein binding and go on to evaluate the functional consequences of these evolutionary changes.

  Evaluation Summary:

  Transient Receptor Potential (TRP) cation channels, related to voltage-gated channels, appeared before plants and animals diverged in evolution and expanded in vertebrates into seven major subfamilies and took multiple essential physiological functions encoding chemical and physical information into electrical signals. In this manuscript, Deny Cabezas-Bratesco and co-workers draw from multiple sequence alignments and available structural information to identify highly conserved features in the transmembrane domains across several major TRP subfamilies in vertebrate and invertebrate animals and even in unicellular organisms. By systematically analyzing their findings, the authors propose a structural framework hinting at common mechanisms utilized by TRP channels to integrate stimuli into electric signals, which has major implications for a wide range of biological processes where TRP channels play a role.

  Evaluation Summary:

  This manuscript provides some clear ideas on the use of next-generation sequencing data to rapidly increase biodiversity inventories and set the basis for future research. The principal objective of this study is to demonstrate how biodiversity information for a hyperdiverse tropical group can be rapidly expanded via targeted field research and large-scale sequencing. The authors use a comprehensive sampling for a tribe of beetles with complicated morphological characters, highlight the existence of multiple undescribed taxa. The database of sequences could set a benchmark for the spatiotemporal evaluation of biodiversity, would support evidence-based conservation planning, and would provide a robust framework for systematic, biogeographic, and evolutionary studies.
