With a current estimate of ~1,000 million tons, mesopelagic fishes likely dominate the world total biomass. However, recent acoustic observations show that biomass could be significantly larger than estimate. Here we combine modelling and sensitivity analysis from Malaspina 2010 Circumnavigation Expedition to previous needs revised at least one order magnitude higher. We there is close relationship between open ocean primary production, energy transfer efficiency phytoplankton in higher what...
Abstract Global patterns of planktonic diversity are mainly determined by the dispersal propagules with ocean currents. However, role that abundance and body size play in determining spatial remains unclear. Here we analyse community structure - β-diversity for several nektonic organisms from prokaryotes to small mesopelagic fishes collected during Malaspina 2010 Expedition. was compared surface transit times derived a global circulation model, revealing significant negative relationship is...
Jellyfish process prey at the same rates as fish, suggesting that a shift to jellyfish-dominated systems is possible.
Abstract The biological pump transports organic carbon produced by photosynthesis to the meso- and bathypelagic zones, latter removing from exchanging with atmosphere over centennial time scales. Organisms living in both zones are supported a passive flux of particles, transported deep-sea through vertical zooplankton migrations. Here we report globally-coherent positive relationships between biomass epi-, meso-, layers average net primary production (NPP). We do so based on global...
Turritopsis dohrnii is the only metazoan able to rejuvenate repeatedly after its medusae reproduce, hinting at biological immortality and challenging our understanding of aging. We present compare whole-genome assemblies T. nonimmortal rubra using automatic manual annotations, together with transcriptome life cycle reversal (LCR) process dohrnii. have identified variants expansions genes associated replication, DNA repair, telomere maintenance, redox environment, stem cell population,...
Relatively warm (12.50–12.75°C) and high-salinity [<35.640 practical salinity units (PSU)] water flowing eastward was detected at the shelf-break during a cruise carried Out in southern Bay of Biscay Spring 1987. The slope current induced formation convergent front separating well-mixed oceanic waters from haline-stratified coastal waters. Very high concentrations dissolved oxygen (295 μmol kg−1) chlorophyll a(>4.5 mg m−3) were found outer edge frontal boundary. Small autotrophic flagellates...
The lack of effective governance is a major concern in small-scale fisheries. implementation that encompasses the three pillars sustainability (social, economic, and ecological) still worldwide challenge. We examined nine stalked barnacle fisheries (Pollicipes pollicipes) across Southwest Europe to better understand relationship between elements sustainability. Our results show nested spatial scales management, access structure, co-management, fisher's participation monitoring surveillance...
The present article describes a structurally novel natural product of the paulomycin family, designated as G (1), obtained from marine strain Micromonospora matsumotoense M-412, isolated Cantabrian Sea sediments collected at 2000 m depth during an oceanographic expedition to submarine Avilés Canyon. Paulomycin is unique since-to our knowledge-it first member family antibiotics lacking paulomycose moiety. It also smallest bioactive reported. Its structure was determined using HRMS and 1D 2D...
In recent years, cooperative management systems have received attention as a means towards sustainable fisheries. Since its inception and for the past 20 gooseneck barnacle fishery in coast of Asturias has been co-managed by assigning Territorial User Rights to fishers׳ associations, allowing fishers participate actively data gathering processes. Here, years landings, in-depth interviews focus groups were used characterize emergence social-ecological properties system. The system consists 7...
Gelatinous zooplankton (GZ) comprise a taxonomically and functionally diverse group of marine organisms which includes ctenophores, cnidarians pelagic tunicates, sharing soft, mostly transparent body texture, high water content lack exoskeleton. They range in size from less than millimetre to nearly 2 m for the cnidarian jellyfish Nemopilema nomurai, some fastest growing metazoans on Earth (Hopcroft et al., 1998), sometimes surpassing crustacean their contribution secondary production (i.e....

Nitrogen stable isotope ratios (δ15N) and body size were used to describe the size-based trophic structure of a deep-sea ecosystem, Avilés submarine Canyon (Cantabrian Sea, Southern Bay Biscay). We analyzed δ15N specimens collected on seasonal basis (March 2012, October May 2013), from variety zones (benthic, pelagic), taxa (from zooplankton through invertebrates fishes giant squids cetaceans), or depths surface 4700 m) that spanned nine orders magnitude in mass. Our data reveal strong...
