Fitness consequences of fish circadian behavioural variation in exploited marine environments

Section Editor rating: 7 / 10

James Reimer –– A nice study examining how fishing affects fish of different chronotypes - important information for a wide range of fisheries-related scientists and managers!
Effects of sandfish (Holothuria scabra) removal on shallow-water sediments in Fiji

Section Editor rating: 8 / 10

James Reimer –– Just as the reviewers and AE stated, loss of sea cucumbers is a global problem - and this study shows just how important these ecosystem engineers can be in ecosystem function.
Citizen science data suggest that a novel rig improves landing rate and reduces injury and handling time in recreational angling with artificial lures in Baltic pike (Esox lucius)

Section Editor rating: 7 / 10

James Reimer –– Completely agree with the AE on this assessment - and thus this article could be important to a wide readership including companies making fishing lures, as well as anglers and scientists.
Shifting reef fish assemblages along a depth gradient in Pohnpei, Micronesia

Section Editor rating: 7 / 10

Robert Toonen –– This one of the only studies on mesophotic marine habitats is this part of the world, and will be a critical study for anyone trying to make generalizations from their own local region across the Pacific. To quote the most critical reviewer, this is "groundbreaking research" of an understudied ecosystem in rarely studied region of the globe.
Infection by Parorchis acanthus (Trematoda) decreases grazing by the keystone gastropod, Littoraria irrorata

Section Editor rating: 8 / 10

James Reimer –– This work examines the ecological importance of parasites, a topic that could be on great significance yet has received little research attention.
The effect of tides on nearshore environmental DNA

Section Editor rating: 8 / 10

Robert Toonen –– There is considerable interest in eDNA, and concurrent debate about the utility, reliability and temporal resolution of the approach. This paper contributes an important understanding of the reliability and temporal scale over which this technique can resolve community differences for tidally-influenced nearshore waters.
Out of Asia: mitochondrial evolutionary history of the globally introduced supralittoral isopod Ligia exotica

Editor rating: 8 / 10

Curtis 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.
The little shrimp that could: phylogeography of the circumtropical Stenopus hispidus (Crustacea: Decapoda), reveals divergent Atlantic and Pacific lineages

Editor rating: 8 / 10

Xavier 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.

Carlos Conte-Junior –– There are few papers that explore fish products.
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.
