    In the original version of this article (Moreno &Gonzalez-Pestana, 2017), published on 9 November 2017, the first sentence of the 'Conclusions' contains an error: the species "M. alfredi" has been wrongfully mentioned. The original publication of this article has been corrected.-The sentence originally read: "This sighting represents the southernmost record of M. birostris and M. alfredi in the southeastern Pacific (12°S)."-The sentence now reads: "This sighting represents the southernmost record of M. birostris in the southeastern Pacific (12°S). © 2019 The Author(s).

    Microplastics in the Antarctic marine system: an emerging area of research
    (Elsevier B.V., 2017) Waller, C.L.; Griffiths H.J.; Waluda, C.M.; Thorpe, S.E.; Loaiza, I.; Moreno, B.; Pacherres, C.O.; Hughes, K.A.
    It was thought that the Southern Ocean was relatively free of microplastic contamination; however, recent studies and citizen science projects in the Southern Ocean have reported microplastics in deep-sea sediments and surface waters. Here we reviewed available information on microplastics (including macroplastics as a source of microplastics) in the Southern Ocean. We estimated primary microplastic concentrations from personal care products and laundry, and identified potential sources and routes of transmission into the region. Estimates showed the levels of microplastic pollution released into the region from ships and scientific research stations were likely to be negligible at the scale of the Southern Ocean, but may be significant on a local scale. This was demonstrated by the detection of the first microplastics in shallow benthic sediments close to a number of research stations on King George Island. Furthermore, our predictions of primary microplastic concentrations from local sources were five orders of magnitude lower than levels reported in published sampling surveys (assuming an even dispersal at the ocean surface). Sea surface transfer from lower latitudes may contribute, at an as yet unknown level, to Southern Ocean plastic concentrations. Acknowledging the lack of data describing microplastic origins, concentrations, distribution and impacts in the Southern Ocean, we highlight the urgent need for research, and call for routine, standardised monitoring in the Antarctic marine system. © 2017

    Southernmost record of the giant manta ray mobula birostris (Walbaum, 1792) in the eastern pacific
    (BioMed Central Ltd., 2017) Moreno, B.; Gonzalez-Pestana, A.
    Background: Manta rays (Mobulidae), Mobula birostris and Mobula alfredi, are widely distributed in tropical and temperate waters. Still, little is known about their movements and their ecological interactions (e.g. behavior and diet). In Peru, M. birostris has only been reported along the northern shore within the Tropical East Pacific Marine Province. No official reports exist from central or south Peru within the Warm Temperate Southeastern Pacific Marine Province. Methods: On December 22nd 2015, a rare sighting of a ~4 m disc width mobulid ray was recorded as video footage near the Palomino Islets, Lima, Peru. Results: In situ observations and subsequent analysis of the footage confirmed that this single mobulid was a M. birostris with a melanistic color morph. Conclusions: This sighting could be explained by the warm El Niño, primary (chl-a), and secondary (zooplankton) productivity events during that same period. This represents the southernmost record of M. birostris in the southeastern Pacific (12°S) and the first report of this species in the Warm Temperate Southeastern Pacific Marine Province and in the Humboldt Current Large Marine Ecosystem. © The Author(s).
