The Tōhoku earthquake and tsunami of March 11, 2011, resulted in unprecedented radioactivity releases from the Fukushima Dai-ichi nuclear power plants to Northwest Pacific Ocean. Results are presented here an international study radionuclide contaminants surface subsurface waters, as well zooplankton fish, off Japan June 2011. A major finding is detection Fukushima-derived 134 Cs 137 throughout waters 30–600 km offshore, with highest activities associated near-shore eddies Kuroshio Current...
Low oxygen zones in coastal and open ocean ecosystems have expanded recent decades, a trend that will accelerate with climatic warming. There is growing recognition low regions of the are also acidified, condition intensify rising levels atmospheric CO2. Presently, however, concurrent effects acidification on marine organisms largely unknown, as most prior studies hypoxia not considered pH levels. We experimentally assessed consequences hypoxic acidified water for early life stage bivalves...
Parallel and idiosyncratic fish adaptation Fish populations respond rapidly to fishing pressure. Within a handful of generations, marked phenotypic change can occur—often smaller body sizes, because it is the big that are usually extracted. Therkildsen et al. examined wild ancestor lineages found polygenic mechanisms underpin this rapid evolutionary capacity (see Perspective by Jørgensen Enberg). Phenotypic happened in two ways: first, multiple small parallel changes hundreds unlinked genes...

Abstract Adaptive evolution and phenotypic plasticity will fuel resilience in the geologically unprecedented warming acidification of earth’s oceans, however, we have much to learn about interactions costs these mechanisms resilience. Here, using 20 generations experimental followed by three reciprocal transplants, investigated relationship between adaptation marine copepod, Acartia tonsa , future global change conditions (high temperature high CO 2 ). We found parallel genes related stress...
How organisms may adapt to rising global temperatures is uncertain, but concepts can emerge from studying adaptive physiological trait variations across existing spatial climate gradients. Many ectotherms, particularly fish, have evolved increasing genetic growth capacities with latitude (i.e. countergradient variation (CnGV) in growth), which are thought be an adaptation primarily strong gradients seasonality. In contrast, evolutionary responses mean temperature often assumed involve...
Experimental studies assessing the potential impacts of ocean acidification on marine organisms have rapidly expanded and produced a wealth empirical data over past decade. This perspective examines four key areas transformative developments in experimental approaches: (1) methodological advances; (2) advances elucidating physiological molecular mechanisms behind observed CO 2 effects; (3) recognition short-term variability as likely modifier species sensitivities (Ocean Variability...
Pelagic ecosystems are changing due to environmental and anthropogenic forces, with uncertain consequences for the ocean's top predators. Epipelagic mesopelagic prey resources differ in quality quantity, but their relative contribution predator diets has been difficult track. We measured mercury (Hg) stable isotopes young (<2 years old) Pacific bluefin tuna (PBFT) species explore influence of foraging depth on growth methylmercury (MeHg) exposure. PBFT total Hg (THg) muscle ranged from 0.61...
Abstract The American sand lance ( Ammodytes americanus , Ammodytidae) and the Northern A. dubius are small forage fishes that play an important functional role in Northwest Atlantic Ocean (NWA). NWA is a highly dynamic ecosystem currently facing increased risks from climate change, fishing energy development. We need better understanding of biology, population dynamics to inform relevant management, adaptation conservation efforts. To meet this need, we synthesized available data on (a)...
Metazoan adaptation to global change relies on selection of standing genetic variation. Determining the extent which this variation exists in natural populations, particularly for responses simultaneous stressors, is essential make accurate predictions persistence future conditions. Here, we identified enabling copepod Acartia tonsa adapt experimental ocean warming, acidification, and combined warming acidification (OWA) over 25 generations continual selection. Replicate populations showed a...
Recruitment patterns of Baltic Sea sprat (Sprattus sprattus) were correlated to time series (i) month- and depth-specific temperature conditions (ii) larval drift inferred from long-term Lagrangian particle simulations. From the latter, we derived an index that likely reflected variable degree annual transport central, deep spawning basins shallow coastal areas Sea. The was significantly (P < 0.001) recruitment success explained, together with stock biomass, 82% overall variability...
Most of the world's living marine resources inhabit coastal environments, where average thermal conditions change predictably with latitude. These latitudinal temperature gradients (CLTG) coincide important ecological clines,e.g., in species diversity or adaptive genetic variations, but how tightly and are linked remains unclear. A first step is to consistently characterize CLTGs. We extracted cells from a global 1°×1° dataset weekly sea surface temperatures (SST, 1982-2012) quantify spatial...
Abstract The role of recombination in genome evolution has long been studied theory, but until recently empirical investigations had limited to a small number model species. Here, we compare the landscape and collinearity between two populations Atlantic silverside ( Menidia menidia ), fish distributed across steep latitudinal climate gradient North American coast. We constructed separate linkage maps for locally adapted from New York Georgia their interpopulation laboratory cross. First,...

Evidence of fishery-induced evolution has been accumulating rapidly from various avenues investigation. Here we review the knowledge gained experimental approaches. The strength experiments is in their ability to disentangle genetic environmental differences. Common garden have provided direct evidence adaptive divergence wild and therefore evolvability traits that influence production numerous species. Most these cases involve countergradient variation physiological, life history,...
