A new record of kelp Lessonia spicata (Suhr) Santelices in the Sub-Antarctic Channels: implications for the conservation of the “huiro negro” in the Chilean coast
Blanca Figuerola –– This study contributes to diversity and biogeography of kelp species at high latitudes of South America with implications for conservation concerns.
Oceanographic habitat and the coral microbiomes of urban-impacted reefs
James Reimer –– Cross-disciplinary work on understanding coral microbiomes on urban reefs.
Sargassum blooms in the Caribbean alter the trophic structure of the sea urchin Diadema antillarum
Salvador Sánchez-Carrillo –– The effects of the increasing Sargassum blooms in the Caribbean on the trophic food web is analyzed
Latitudinal variation in phlorotannin contents from Southwestern Atlantic brown seaweeds
Blanca Figuerola –– This article can help to understand the ecological drivers of defensive chemistry in seaweeds.
262 Voyages Beneath the Sea: a global assessment of macro- and megafaunal biodiversity and research effort at deep-sea hydrothermal vents
Craig Moyer –– This is a timely and important survey of global vent fauna diversity, especially in light of impending undersea mining operations.
Differential gene expression in skeletal organic matrix proteins of scleractinian corals associated with mixed aragonite/calcite skeletons under low mMg/Ca conditions
Anastazia Banaszak –– This work considers the molecular and mineralogical aspects of the biomineralization mechanism in stony corals. It should be of iparticular nterest to coral biologists and geochemists.
Polyp expansion of passive suspension feeders: a red coral case study
Anastazia Banaszak –– Using a combination of in situ and flume-based observations, the data indicate that passive suspension feeders may rely on their ability to maximise prey capture during food pulses and thus allows us to better understand trophic dynamics of red corals.
Factors affecting relative abundance of low-mobility fishing resources: spiny lobster in the Galapagos Marine Reserve
Donald Kramer –– Although not my specific research area, both reviewers highlight the relevance of this article to standardizing fisheries catch data. It is a very data-rich study with substantial analytical effort. It should prove useful in emphasizing that traditional approaches to stock assessment need modification for species with low mobility.
RAD genotyping reveals fine-scale population structure and provides evidence for adaptive divergence in a commercially important fish from the northwestern Pacific Ocean
Rodolfo Jaffé –– This study employs RAD genotyping to assess population structure local adaptation in a commercially important fish from the northwestern Pacific Ocean.
Multi-gene incongruence consistent with hybridisation in Cladocopium (Symbiodiniaceae), an ecologically important genus of coral reef symbionts
Anastazia Banaszak –– This study lays the groundwork for future studies on the hybridization in the Symbiodiniaceae, which is a much understudied field of research.
