Channeling of carbamoyl phosphate to the pyrimidine and arginine biosynthetic pathways in the deep sea hyperthermophilic archaeon Pyrococcus abyssi. (1/1633)

The kinetics of the coupled reactions between carbamoyl-phosphate synthetase (CPSase) and both aspartate transcarbamoylase (ATCase) and ornithine transcarbamoylase (OTCase) from the deep sea hyperthermophilic archaeon Pyrococcus abyssi demonstrate the existence of carbamoyl phosphate channeling in both the pyrimidine and arginine biosynthetic pathways. Isotopic dilution experiments and coupled reaction kinetics analyzed within the context of the formalism proposed by Ovadi et al. (Ovadi, J., Tompa, P., Vertessy, B., Orosz, F., Keleti, T., and Welch, G. R. (1989) Biochem. J. 257, 187-190) are consistent with a partial channeling of the intermediate at 37 degrees C, but channeling efficiency increases dramatically at elevated temperatures. There is no preferential partitioning of carbamoyl phosphate between the arginine and pyrimidine biosynthetic pathways. Gel filtration chromatography at high and low temperature and in the presence and absence of substrates did not reveal stable complexes between P. abyssi CPSase and either ATCase or OTCase. Thus, channeling must occur during the dynamic association of coupled enzymes pairs. The interaction of CPSase-ATCase was further demonstrated by the unexpectedly weak inhibition of the coupled reaction by the bisubstrate analog, N-(phosphonacetyl)-L-aspartate (PALA). The anomalous effect of PALA suggests that, in the coupled reaction, the effective concentration of carbamoyl phosphate in the vicinity of the ATCase active site is 96-fold higher than the concentration in the bulk phase. Channeling probably plays an essential role in protecting this very unstable intermediate of metabolic pathways performing at extreme temperatures.  (+info)

Sex-biased dispersal in sperm whales: contrasting mitochondrial and nuclear genetic structure of global populations. (2/1633)

The social organization of most mammals is characterized by female philopatry and male dispersal. Such sex-biased dispersal can cause the genetic structure of populations to differ between the maternally inherited mitochondrial DNA (mtDNA) and the bi-parental nuclear genome. Here we report on the global genetic structure of oceanic populations of the sperm whale, one of the most widely distributed mammalian species. Groups of females and juveniles are mainly found at low latitudes, while males reach polar waters, returning to tropical and subtropical waters to breed. In comparisons between oceans, we did not find significant heterogeneity in allele frequencies of microsatellite loci (exact test; p = 0.23). Estimates of GST = 0.001 and RST = 0.005 also indicated negligible if any nuclear DNA differentiation. We have previously reported significant differentiation between oceans in mtDNA sequences. These contrasting patterns suggest that interoceanic movements have been more prevalent among males than among females, consistent with observations of females being the philopatric sex and having a more limited latitudinal distribution than males. Consequently, the typical mammalian dispersal pattern may have operated on a global scale in sperm whales.  (+info)

RecD function is required for high-pressure growth of a deep-sea bacterium. (3/1633)

A genomic library derived from the deep-sea bacterium Photobacterium profundum SS9 was conjugally delivered into a previously isolated pressure-sensitive SS9 mutant, designated EC1002 (E. Chi and D. H. Bartlett, J. Bacteriol. 175:7533-7540, 1993), and exconjugants were screened for the ability to grow at 280-atm hydrostatic pressure. Several clones were identified that had restored high-pressure growth. The complementing DNA was localized and in all cases found to possess strong homology to recD, a DNA recombination and repair gene. EC1002 was found to be deficient in plasmid stability, a phenotype also seen in Escherichia coli recD mutants. The defect in EC1002 was localized to a point mutation that created a stop codon within the recD gene. Two additional recD mutants were constructed by gene disruption and were both found to possess a pressure-sensitive growth phenotype, although the magnitude of the defect depended on the extent of 3' truncation of the recD coding sequence. Surprisingly, the introduction of the SS9 recD gene into an E. coli recD mutant had two dramatic effects. At high pressure, SS9 recD enabled growth in the E. coli mutant strain under conditions of plasmid antibiotic resistance selection and prevented cell filamentation. Both of these effects were recessive to wild-type E. coli recD. These results suggest that the SS9 recD gene plays an essential role in SS9 growth at high pressure and that it may be possible to identify additional aspects of RecD function through the characterization of this activity.  (+info)

Bacillus marismortui sp. nov., a new moderately halophilic species from the Dead Sea. (4/1633)

A group of 91 moderately halophilic, Gram-positive, rod-shaped strains were isolated from enrichments prepared from Dead Sea water samples collected 57 years ago. These strains were examined for 117 morphological, physiological, biochemical, nutritional and antibiotic susceptibility characteristics. All strains formed endospores and were motile, strictly aerobic and positive for catalase and oxidase. They grew in media containing 5-25% (w/v) total salts, showing optimal growth at 10% (w/v). Eighteen strains were chosen as representative isolates and were studied in more detail. All these strains had mesodiaminopimelic acid in the cell wall and a DNA G + C content of 39.0-42.8 mol%; they constitute a group with levels of DNA-DNA similarity of 70-100%. The sequences of the 16S rRNA genes of three representative strains (strains 123T, 557 and 832) were almost identical (99.9%), and placed the strains in the low G + C content Gram-positive bacteria. On the basis of their features, these isolates should be regarded as members of a new species of the genus Bacillus, for which the name Bacillus marismortui sp. nov. is proposed. The type strain is strain 123T (= DSM 12325T = ATCC 700626T = CIP 105609T = CECT 5066T).  (+info)

Climate and satellite indicators to forecast Rift Valley fever epidemics in Kenya. (5/1633)

All known Rift Valley fever virus outbreaks in East Africa from 1950 to May 1998, and probably earlier, followed periods of abnormally high rainfall. Analysis of this record and Pacific and Indian Ocean sea surface temperature anomalies, coupled with satellite normalized difference vegetation index data, shows that prediction of Rift Valley fever outbreaks may be made up to 5 months in advance of outbreaks in East Africa. Concurrent near-real-time monitoring with satellite normalized difference vegetation data may identify actual affected areas.  (+info)

The diving physiology of bottlenose dolphins (Tursiops truncatus). I. Balancing the demands of exercise for energy conservation at depth. (6/1633)

During diving, marine mammals must rely on the efficient utilization of a limited oxygen reserve sequestered in the lungs, blood and muscles. To determine the effects of exercise and apnea on the use of these reserves, we examined the physiological responses of adult bottlenose dolphins (Tursiops truncatus) trained to breath-hold on the water surface or to dive to submerged targets at depths between 60 and 210 m. Changes in blood lactate levels, in partial pressures of oxygen and carbon dioxide and in heart rate were assessed while the dolphins performed sedentary breath-holds. The effects of exercise on breath-hold capacity were examined by measuring heart rate and post-dive respiration rate and blood lactate concentration for dolphins diving in Kaneohe Bay, Oahu, Hawaii. Ascent and descent rates, stroke frequency and swimming patterns were monitored during the dives. The results showed that lactate concentration was 1.1+/-0.1 mmol l(-1) at rest and increased non-linearly with the duration of the sedentary breath-hold or dive. Lactate concentration was consistently higher for the diving animals at all comparable periods of apnea. Breakpoints in plots of lactate concentration and blood gas levels against breath-hold duration (P(O2), P(CO2)) for sedentary breath-holding dolphins occurred between 200 and 240 s. In comparison, the calculated aerobic dive limit for adult dolphins was 268 s. Descent and ascent rates ranged from 1.5 to 2.5 m s(-1) during 210 m dives and were often outside the predicted range for swimming at low energetic cost. Rather than constant propulsion, diving dolphins used interrupted modes of swimming, with more than 75 % of the final ascent spent gliding. Physiological and behavioral measurements from this study indicate that superimposing swimming exercise on apnea was energetically costly for the diving dolphin but was circumvented in part by modifying the mode of swimming.  (+info)

Bacterial swimming strategies and turbulence. (7/1633)

Most bacteria in the ocean can be motile. Chemotaxis allows bacteria to detect nutrient gradients, and hence motility is believed to serve as a method of approaching sources of food. This picture is well established in a stagnant environment. In the ocean a shear microenvironment is associated with turbulence. This shear flow prevents clustering of bacteria around local nutrient sources if they swim in the commonly assumed "run-and-tumble" strategy. Recent observations, however, indicate a "back-and-forth" swimming behavior for marine bacteria. In a theoretical study we compare the two bacterial swimming strategies in a realistic ocean environment. The "back-and-forth" strategy is found to enable the bacteria to stay close to a nutrient source even under high shear. Furthermore, rotational diffusion driven by thermal noise can significantly enhance the efficiency of this strategy. The superiority of the "back-and-forth" strategy suggests that bacterial motility has a control function rather than an approach function under turbulent conditions.  (+info)

Are there mechanical limits to size in wave-swept organisms? (8/1633)

Hydrodynamic forces imposed by ocean waves are thought to limit the size of nearshore plants and animals, but it has proved difficult to determine the mechanism. Explanations based on the scaling mismatch between hydrodynamic accelerational forces and the strength of organisms do not work. Mechanisms that incorporate the allometry of drag and strength accurately predict the maximal size of intertidal algae but not of animals, and internally imposed inertial forces may explain the limits to size in large kelps. The general question of size in wave-swept organisms remains open and intriguing.  (+info)

Bacteria and archaea dominate the biomass of benthic deep-sea ecosystems at all latitudes, playing a crucial role in global biogeochemical cycles, but their macroscale patterns and macroecological drivers are still largely unknown. We show the results of the most extensive field study conducted so far to investigate patterns and drivers of the distribution and structure of benthic prokaryote assemblages from 228 samples collected at latitudes comprising 34°N to 79°N, and from ca. 400- to 5570-m depth. We provide evidence that, in deep-sea ecosystems, benthic bacterial and archaeal abundances significantly increase from middle to high latitudes, with patterns more pronounced for archaea, and particularly for Marine Group I Thaumarchaeota. Our results also reveal that different microbial components show varying sensitivities to changes in temperature conditions and food supply. We conclude that climate change will primarily affect deep-sea benthic archaea, with important consequences on global ...

The goal of the Arabian Sea section of the TARA oceans expedition was to study large particulate matter (LPM , 100 μm) distributions and possible impact of associated midwater biological processes on vertical carbon export through the oxygen minimum zone (OMZ) of this region. We propose that observed spatial patterns in LPM distribution resulted from the timing and location of surface phytoplankton bloom, lateral transport, microbial processes in the core of the OMZ, and enhanced biological processes mediated by bacteria and zooplankton at the lower oxycline. Indeed, satellite-derived net primary production maps showed that the northern stations of the transect were under the influence of a previous major bloom event while the most southern stations were in a more oligotrophic situation. Lagrangian simulations of particle transport showed that deep particles of the northern stations could originate from the surface bloom while the southern stations could be considered as driven by 1-D vertical ...
This study examines the potential effects of ocean acidification on countries and fisheries of the Mediterranean Sea. The implications for seafood security and supply are evaluated by examining the sensitivity of the Mediterranean to ocean acidification at chemical, biological, and macro-economic levels. The limited information available on impacts of ocean acidification on harvested (industrial, recreational, and artisanal fishing) and cultured species (aquaculture) prevents any biological impact assessment. However, it appears that non-developed nations around the Mediterranean, particularly those for which fisheries are increasing, yet rely heavily on artisanal fleets, are most greatly exposed to socioeconomic consequences from ocean acidification.

Some regions of the deep ocean floor support abundant populations of organisms, despite being overlain by water that contains very little oxygen, according to an international study led by scientists at the United Kingdoms National Oceanography Center, Southampton. But global warming is likely to exacerbate oxygen depletion and thereby reduce biodiversity in these regions, they warn.. The sunlit surface waters tend to be well oxygenated as a result of their connection with the atmosphere. Here, tiny marine algae called phytoplankton thrive. When they die and sink, they are degraded by bacteria, using oxygen from the water column.. In regions of high plant growth, this can result in the natural development of mid-water oxygen minimum zones (OMZs), especially where oxygen is not replenished by mixing of the water column. Where they touch the continental slope, OMZs create strong seafloor oxygen gradients at depths between 100 and 1000 m.. In addition to low oxygen, sediments within OMZs often ...
Multidisciplinary ocean observing activities provide critical ocean information to satisfy ever-changing socioeconomic needs and require coordinated implementation. The upper oxycline (transition between high and low oxygen waters) is fundamentally important for the ecosystem structure and can be a useful proxy for multiple observing objectives connected to eastern boundary systems (EBSs) that neighbor oxygen minimum zones (OMZs). The variability of the oxycline and its impact on the ecosystem (VOICE) initiative demonstrates how societal benefits drive the need for integration and optimization of biological, biogeochemical, and physical components of regional ocean observing related to EBS. In liaison with the Global Ocean Oxygen Network, VOICE creates a roadmap toward observation-model syntheses for a comprehensive understanding of selected oxycline-dependent objectives. Local to global effects, such as habitat compression or deoxygenation trends, prompt for comprehensive observing of the oxycline on
Management strategies use information provided by research and tools that can be used to make sound decisions to effectively conserve marine resources. Baseline research about organism and community sensitivity to ocean acidification is incorporated into these strategies, in an effort to sustain these resources for the future. Before management plans can be created it is necessary to have baseline research about the effects of ocean acidification on marine resources, such as Pacific oysters, Dungeness crabs and rockfish. The OAP funds NOAA Fisheries Science Centers to expose various life stages of valuable species to present and future acidification conditions. The biological response research is then incorporated into models that can be used to create tools for managers to use so that they can test different scenarios on species populations and habitats. Modeling efforts led by Woods Hole Oceanographic Institution are now being used to produce one of these tools for Atlantic sea scallop ...
Oxygen Minimum Zones (OMZ) are the places in the world ocean where oxygen saturation in the water column is at its lowest. This zone typically occurs at depths of about 200 to 1,000 meters. The AOG lab is interested in OMZs because of their importance in controlling carbon and nitrogen cycling in the oceans. OMZ water is exposed to the rain of sinking organic matter, which we evaluate using our drifting net traps and in situ incubators. Bacteria and archea feed on this organic matter and oxygen is used. Thus, the concentration of oxygen in deep water is dependent on the amount of oxygen it had when it was at the surface minus depletion by deep sea organisms.. In many OMZ regions oxygen actually reaches zero, in which case the OMZ can be called an ODZ (oxygen deficient zone). ODZs provide appropriate conditions to enable substantial nitrogen loss because in the absence of oxygen, nitrate represents the next best electron acceptor available for respiration. Starting with organic nitrogen ...
Temperatures throughout the Jurassic and Cretaceous are generally thought to have been relatively warm, and consequently dissolved oxygen levels in the ocean were lower than today - making anoxia easier to achieve. However, more specific conditions are required to explain the short-period (less than a million years) oceanic anoxic events. Two hypotheses, and variations upon them, have proved most durable.. One hypothesis suggests that the anomalous accumulation of organic matter relates to its enhanced preservation under restricted and poorly oxygenated conditions, which themselves were a function of the particular geometry of the ocean basin: such a hypothesis, although readily applicable to the young and relatively narrow Cretaceous Atlantic (which could be likened to a large-scale Black Sea, only poorly connected to the World Ocean), fails to explain the occurrence of coeval black shales on open-ocean Pacific plateaus and shelf seas around the world. There are suggestions, again from the ...

Little is known about the ocean temperatures long-term response to climate perturbations owing to limited observations and a lack of robust reconstructions. Although most of the anthropogenic heat added to the climate system has been taken up by the ocean up until now, its role in a century and beyond is uncertain. Here, using noble gases trapped in ice cores, we show that the mean global ocean temperature increased by 2.57 ± 0.24 degrees Celsius over the last glacial transition (20,000 to 10,000 years ago). Our reconstruction provides unprecedented precision and temporal resolution for the integrated global ocean, in contrast to the depth-, region-, organism- and season-specific estimates provided by other methods. We find that the mean global ocean temperature is closely correlated with Antarctic temperature and has no lead or lag with atmospheric CO2, thereby confirming the important role of Southern Hemisphere climate in global climate trends. We also reveal an enigmatic 700-year warming during

Time series of surface wind and upper ocean temperature and velocity, obtained from equatorial moorings along 110°W, are used to assess the importance of various oceanic and atmospheric processes in the variation of the mixed layer temperature for the period January 1986 to June 1988. This period coincides with the onset and development of the 1986-87 El Niño-Southern Oscillation warm event and a subsequent cold event in 1988. Results of the temperature equation analyses indicate that seasonal and interannual variability of sea surface temperature (SST) in the eastern Pacific cannot be accounted for by observed surface heat flux; oceanic processes play an important role in the heating of the surface water. Although no single process dominated SST change, the most important processes in the mean balance were the net incoming surface heat flux, the penetrative solar radiation, and the vertical turbulent flux out the bottom of the mixed layer. The mean vertical entrainment could not be estimated ...

The emergence of the Law of the Sea Convention and establishment of Exclusive Economic Zones has given coastal states extensive and comprehensive rights and obligations over marine resources in vast areas of ocean. Wise management of ocean resources is essential if the full economic potential of these new entitlements is to be realised. To ensure the continuing biological productivity of these areas, the level and type of development of activities such as waste dumping, mineral extraction, recreation, industrial and urban growth, fisheries and aquaculture, need to be controlled, and interactions of these often conflicting activities resolved by management.. This MSc is a full-time one-year course, consisting of 9 months taught course and 3 months research project, and examined by continuous assessment. The course provides theoretical and practical training in measuring and quantifying marine resources and the effects of conflicting usage upon them. It provides a sound scientific basis on which ...
My earliest research focused on evolution in the Southern Ocean and deep sea using octopuses as a model system. This research highlighted connections between the worlds oceans, linked evolutionary radiations to climatic events through dated phylogenies, and helped explain how Southern Ocean fauna survived the massive disturbances caused by Pliocene-Pleistocene glacial cycles. My paper on the evolutionary origins of deep-sea octopuses was the top highlight in the Census of Marine Life press release at the 1st World Congress of Marine Biodiversity, Valencia 2008. More recently my group been studying the ecology and evolution of sponges and corals in the deep waters of Irelands Atlantic margin and I have just been awarded more than a million euro by Science Foundation Ireland / Marine Institute to explore their biodiscovery potential. Im an active field scientist and have led numerous research cruises as Chief Scientist. Im a former president of the Cephalopod International Advisory Council, a ...
Marine metagenomics provides an unique opportunity to study marine microorganism communities. The large amount of data available from studies like the Global Ocean Sampling (GOS) Expedtion is appealing for comparative studies of gene content and its link to the environment.. ...
Yes, Thomas, that is something that is going to become an issue in the near future. As the oceans warm they begin to stratify meaning reduced mixing of deep waters with the surface. This leads to declines in upwelling of nutrients to the surface and is thought to be the cause of the 40% reduction in phytoplankton in the last century. Oxygen levels in the ocean will decline simply because oxygen is less soluble in warmer water, but the stratification also reduces ventilation of oxygen to deeper waters too. So marine organisms living on the ocean floor will inevitably be one of the first to suffer.. An expansion of oxygen minimum zones in the worlds oceans have been recently observed, some palaeo data show that de-oxygenation occurs in times of global warming and ocean anoxia (oxygen depletion) is linked to some major extinction events, most notably the Permian Extinction. So there is growing evidence to support this relatively new area of research. Ocean Acidification, mass coral bleaching due ...
Recent research by ESA Living Planet Fellow Marco Bellacicco in the frame of project PHYSIOGLOB gives new insights on how the choice of the regression
abstract = {An eddy is a feature associated with a rotating body of fluid, surrounded by a ring of shearing fluid. In the ocean, eddies are 10 to 150 km in diameter, are spawned by boundary currents and baroclinic instabilities, may live for hundreds of days, and travel for hundreds of kilometers. Eddies are important in climate studies because they transport heat, salt, and nutrients through the worlds oceans and are vessels of biological productivity. The study of eddies in global ocean-climate models requires large-scale, high-resolution simulations. This poses a problem for feasible (timely) eddy analysis, as ocean simulations generate massive amounts of data, causing a bottleneck for traditional analysis workflows. To enable eddy studies, we have developed an in situ workflow for the quantitative and qualitative analysis of MPAS-Ocean, a high-resolution ocean climate model, in collaboration with the ocean model research and development process. Planned eddy analysis at high spatial and ...

In multidisciplinary efforts to understand and manage our planet, contemporary ocean science plays an essential role. Volumes 13 and 14 of The Sea focus on two of the most important components in the field of ocean science today -- the coastal ocean and its interactions with the deep sea, and coupled physical-biogeochemical and ecosystem dynamics.
This is a composite MODIS image showing the green wave of spring in North America and sea surface temperature in the ocean, collected over an 8-day period during the first week in April 2000. On land, the darker green pixels show where the most green foliage is being produced due to photosynthetic activity. Yellows on land show where there is little or no productivity and red is a boundary zone. In the ocean, orange and yellows show warmer waters and blues show colder values.. ...

Im pretty busy this week, but if I can get readers to look at one article, it would be the very balanced one that appeared in The Economist on ocean acidification.. The articles subtitle is ocean acidification threatens the worlds oceans, but quantifying the risks is hard, which is probably a fair statement given the current state of play in the research. It has always been suggested that there will likely to be winners and losers in the ocean from acidification, and this year some researchers have proposed that a meta-analysis of studies to date indicate that sea life may be more resilient than originally thought. This has been immediately attacked by other researchers pointing out the complexity of the problem: you have to look at how lower pH affects organisms at all stages of life, as well as warming ocean temperatures, and nutrient levels too.. There are still studies just coming out which have tried to work out more details as to different species responses. Here are a few:. * its ...
