Clarifying a trophic black box: stable isotope analysis reveals unexpected dietary variation in the Peruvian anchovy Engraulis ringens
James Reimer –– As one of the reviewers stated, "Deepens the knowledge, although on microscale, about the trophic complexity of the Humboldt current system" with regards to an important commercial fish species, the Peruvian anchovy.
Alternative bait trials in the Barents Sea snow crab fishery
Magnus Johnson –– This paper is likely to attract some attention, and hopefully stimulate some discussion, given the potential controversy over using mammal waste as bait for crustaceans.
Towards an in-depth characterization of Symbiodiniaceae in tropical giant clams via metabarcoding of pooled multi-gene amplicons
Robert Toonen –– A new pooled multi-gene sequencing approach using three targeted amplicon markers (ITS-2, 28S LSU & chloroplast 23S) for evaluating the diversity of Symbiodiniaceae in a given holobiont sample. This method is readily scalable and offers improved resolution for roughly equivalent costs, making it a highly attractive tool for the study of symbiont diversity.
Century-scale changes in phytoplankton phenology in the Gulf of Maine
Robert Toonen –– To quote one of the referees: Time series lengthy enough to assess climate impacts are still rare so bringing together data to produce a long time series is very useful. This study demonstrates that some of the changes related to climate effects are what we might expect (the autumn bloom is now later) but some are unexpected and require more detailed understanding.
Identification of candidate reference genes for qRT-PCR normalization studies of salinity stress and injury in Onchidium reevesii
Oren Levy –– A new reference genes for using qRT-PCR normalisation Onchidium reevesii
Age, growth, mortality and recruitment of thin sharpbelly Toxabramis swinhonis Günther, 1873 in three shallow lakes along the middle and lower reaches of the Yangtze River basin, China
Suchana Chavanich –– No previous study on this
Genotypic variation in disease susceptibility among cultured stocks of elkhorn and staghorn corals
Robert Toonen –– In the words of one referee, coral restoration is a rapidly increasingly area of research, and one that is sadly needed. This study reports significant genetic variation in disease susceptibility among cultured corals, and the importance of including disease resistance among the desirable traits for restoration efforts.
On the half-life of thiocyanate in the plasma of the marine fish Amphiprion ocellaris: implications for cyanide detection
Robert Toonen –– Cyanide fishing is not only harmful to the environment and the individuals who undertake this activity, but also to those who inadvertently support it by purchasing fish that are poisoned and will not survive. There is no currently rapid and cost-effective test for the determination of cyanide exposure in marine ornamental and other live fish markets. To quote one referee, this paper is a critical first step: "understanding the pharmacokinetics of cyanide in marine fish will allow for the identification of a viable biomarker that can lead to the development of a rapid onsite test for cyanide detection in fish."
Eyes in Staurozoa (Cnidaria): a review
Linda Holland –– This article pulls together information on photoreceptors in a poorly understood group of cnidarians. In an era when zoology is often ignored, this is a valuable contribution.
Heat stress compromises epithelial integrity in the coral, Acropora hyacinthus
Anastazia Banaszak –– With coral diseases and bleaching on the rise, it is important to have more information on how corals react to heat stress.
