Editor rating: 8 / 10Curtis Daehler –– This work provides genetic evidence suggesting the native range of a widely distributed animal that was accidentally spread by humans starting hundreds of years ago.
Editor rating: 8 / 10Xavier Pochon –– This study provides the first range-wide phylogeographic study of the banded coral shrimp S. hispidus, extending across more than 27,000 km of the globe. Coalescence analysis brings evidence that an isolated Indo-Pacific lineage evolved from a rare dispersal event from the Atlantic around South Africa via the Benguela Current, thereby colonizing the Indian and Pacific Oceans, followed by dispersal across the Indo-Pacific in the last 200,000 years. Surprisingly, this benthic coral reef associated shrimp shows a single haplotype dominating the largest continuous tropical oceanic expanse on the planet.
Editor rating: 7 / 10Gerrit Beemster –– Epigenetic regulation is rapidly becoming a new regulatory mechanism in developmental processes and this study is a nice contribution to that field using a non model species.
Editor rating: 7 / 10Tatiana Vishnivetskaya –– Metal resistant strain from cold environments could be useful for bioremediation at low temperatures
Editor rating: 7 / 10Maria Cristina Albertini –– Important information has been disclosed in the paper.
Editor rating: 8 / 10Xavier 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.
Editor rating: 7 / 10Marc Robinson-Rechavi –– This study allows to link natural variation in morphology with genetic divergence in expression patterns, thus helping link ecology to molecular genomics.
Editor rating: 7 / 10Donald Kramer –– Although only dealing with a single invasive species, it is a very thorough and interesting analysis of the potential for oil rigs to move fish (and potentially other marine species) around the world.
Editor rating: 8 / 10Heiko Enderling –– This article discusses the contributions of quantitative models in predicting biology, and makes an important point about the balance of simplicity/complexity/accuracy/usefulness of biophysical models. If simple models capture biological complexity, the use of more detailed models must be properly justified.
Editor rating: 8 / 10Todd 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.
