Delivery and fate of fluvial water and sediment to the sea: a marine geologist's view of European rivers
Authors: Milliman John D.
Published: October 2008

Despite their relatively small drainage areas, European rivers reflect a wide variety of hydrologic regimes, although with very few exceptions they have been strongly affected by human activity. Scandinavian rivers (particularly those draining Iceland and western Norway) can have high runoff, and, except for those draining Iceland, all have very low suspended and dissolved sediment loads. Northern and western European rivers have somewhat lower runoff, among the lowest suspended sediment yields in the world, and anthropogenically enhanced dissolved solid loads. Annual discharge of many of these rivers appears to vary inversely with the North Atlantic Oscillation index. Rivers discharging from the southern Alps into the Mediterranean Sea have relatively high runoff, high suspended sediment yields (reflecting younger, more easily erodable rocks as well as generally smaller drainage basins), and high dissolved yields, although presumably with somewhat less human influence. European rivers and their estuaries tend to reflect the terrestrial environments of their drainage basins (i.e. climate, landscape geomorphology, geology), but they also display strong anthropogenic signatures. Sediment erosion increased dramatically in the last several millenia in response to deforestation, farming and mining. In the past 50 years, however, increased soil conservation and local reversion of agricultural land to forest, as well as river diversion and dam construction, have decreased the suspended sediment loads of many European rivers. Improved mining and manufacturing techniques, as well as more effective use of fertilizers and improved waste treatment, almost surely will result in lower dissolved solids and nutrient fluxes to the coastal environments, which presently are the highest in the world. The long-range effects of changed land use on estuarine and coastal environments remain to be seen, although decreased sediment loads in the past 20-40 years have already resulted in increased shoreline erosion. Decreased nutrient fluxes almost certainly will affect water quality in European coastal waters, and decreased silicate delivery by some dammed rivers may result in proliferation of new (and perhaps harmful) estuarine and coastal ecosystems. Everything points to further changes as European rivers and their drainage basins continue to change in the coming years.
Emergence in pelagic communities
Authors: Reynolds C. S.
Published: October 2008

Pelagic systems, those based on the open waters of large lakes and seas, provide excellent opportunities for ecological study. This is because, the vastness of the oceans apart, pelagic ecosystems operate on short space and time scales. This affords important opportunities to study the emergence of ecosystems and the basis of striking high-order patterns of ecosystem behaviour. The essay seeks an outline of the processes by which the biologies of individual organisms - the largest functional, controlled units in the ecosystem - interact and bias the outcomes in favour of particular network structures recognised by ecologists. Populations build, communities assemble, ecosystems function but always in ways that relate to the match between the adaptations and performances of individual species and the capacities of the environments in which they find themselves. The paper attempts to discern the linkages between the biology of individual and the ways that ecosystems are put together, between organisms and organisation. Drawing on the advantages of absolutely short generation times among the producers, consumers and heterotrophs of the pelagic, I seek to sample the ascendant pathways of ecosystem synthesis, noting the energetic decisions which select for particular outcomes. However, the simple organisational state of many pelagic communities reminds us that ascendancy is frequently restrained by a scarcity of resources and tempered by the frequent intervention of abiotic factors. The presentation does not seek to prove any point about systems: it attempts to re-affirm what is known about organisational hierarchies; then, using approximate quantities, the points of bifurcation between alternative organisational structures are nominated; drawing upon suppositions about the dissipation of energy, the organisational underpinning of function at the level of the whole ecosystem is proposed. Corroboration from observations from the real world is sought throughout.
Mesoscale eddies in the Subantarctic Front-Southwest Atlantic
Authors: Glorioso Pablo D. , Piola Alberto R. , Leben Robert R.
Published: October 2008

Satellite and ship observations in the southern southwest Atlantic (SSWA) reveal an intense eddy field and highlight the potential for using continuous real-time satellite altimetry to detect and monitor mesoscale phenomena with a view to understanding the regional circulation. The examples presented suggest that mesoscale eddies are a dominant feature of the circulation and play a fundamental role in the transport of properties along and across the Antarctic Circumpolar Current (ACC). The main ocean current in the SSWA, the Falkland-Malvinas Current (FMC), exhibits numerous embedded eddies south of 50°S which may contribute to the patchiness, transport and mixing of passive scalars by this strong, turbulent current. Large eddies associated with meanders are observed in the ACC fronts, some of them remaining stationary for long periods. Two particular cases are examined using a satellite altimeter in combination with in situ observations, suggesting that cross-frontal eddy transport and strong meandering occur where the ACC flow intensifies along the sub-Antarctic Front (SAF) and the Southern ACC Front (SACCF).
Observations on reproductive features of three species of Eunicidae (Polychaeta) associated with Posidonia oceanica seagrass meadows in the Mediterranean Sea
Authors: Gambi M. C. , Cigliano M.
Published: October 2008

Observations on the reproductive features are provided for three species of Eunicidae (Lysidice ninetta Audouin and Milne Edwards, Lysidice collaris Grube and Nematonereis unicornis (Grube)). They all occur in Posidonia oceanica meadows as borers in the sheaths. The material examined was collected during several studies on P. oceanica meadows conducted at various times of the year and in different years along the coasts of Sardinia and the Ischia islands (Tyrrhenian Sea), and Otranto (Southern Adriatic Sea). All individuals of the three species were measured (width 3rd chaetiger, diameter of eyes), and checked for presence of gametes. In each of the females recognized, egg diameter was measured. To integrate the observations, living specimens were collected in March 2003 and reared in the laboratory until August 2003 to check for gamete maturation; mature males were fixed for analysis of the structure of the spermatozoa by transmission electron microscopy (TEM). All three species studied are gonochoric. For both species of Lysidice gametes occurred in individuals with a width greater than 0.8 mm. The overall scarcity of mature males and females observed with respect to the total number of specimens collected is probably due to the dimensional constraint exerted by the sheaths. In Lysidice spp. specimens with small developing oocytes were observed in January-February and reached their maximum diameter between June and August (157 µm). Gametes were located mainly in the posterior part of the body, and an enlargement of the eyes (almost doubled in size) characterized mature specimens close to spawning. N. unicornis is a smaller species, and it is less frequent in Posidonia sheaths than Lysidice spp.; individuals with gametes had a width greater than 0.55 mm. A few mature specimens were observed between March and May with a maximum egg diameter of about 155 µm. In this species maturation of the gametes is coupled with a huge enlargement of the eyes (ten-times larger than in immature individuals), while the posterior part of the body is swollen and full of mature gametes, indicating reproduction by schizogamy. Analysis of mature spermatozoa of the three eunicids revealed a similar morphology, which is that of an “ect-aquasperm” type, typical of many free-spawning species with external fertilization. The nucleus is round and globose (2.5 µm diameter) and the acrosome, slightly different among the three species, has the general shape of a truncate sub-cone.

Authors: Della Ca' Nicola , Motti Elena , Catellani Marta
Published: October 2008

Selectively substituted phenanthridine derivatives are obtained by a facile reaction of o‐alkylated aryl iodides, o‐bromoarenesulfonylanilines and activated olefins in the presence of palladium and norbornene as catalysts. The reaction takes place under mild conditions to give the products in satisfactory yields using readily available starting materials.
Phenotypic consequences of a novel SCO2 gene mutation
Authors: Verdijk Rob M. , de Krijger Ronald , Schoonderwoerd Kees , Tiranti Valeria , Smeets Hubert , Govaerts Lutgarde C.P. , de Coo René
Published: October 2008

SCO2 is a cytochrome c oxidase (COX) assembly gene. Mutations in the SCO2 gene have been associated with fatal infantile cardioencephalomyopathy. We report on the phenotype of a novel SCO2 mutation in two siblings with fatal infantile cardioencephalomyopathy. The index patient died of heart failure at 25 days of age. Muscle biopsy was performed for histology and biochemical study of the oxidative phosphorylation system complexes. The entire coding region of the SCO2 gene was sequenced. Autopsy was performed on the index patient and on a female sibling delivered at 23 weeks of gestation following termination of pregnancy during which amniocentesis and genetic testing had been performed. Muscle biopsy and biochemical analysis of heart and skeletal muscle detected a severe isolated COX‐IV deficiency. Pathologic findings in both patients confirmed hypertrophic cardiomyopathy. Sequencing of the SCO2 gene showed compound heterozygous mutation; the common E140K mutation and a novel W36X nonsense mutation. Newborns with a combination of hypotonia and cardiomyopathy should be evaluated for multiple congenital anomaly syndromes, inborn errors of metabolism and mitochondrial derangements, and may require extensive diagnostic testing. Mutations in the SCO2 gene are a cause of prenatal‐onset hypertrophic cardiomyopathy. © 2008 Wiley‐Liss, Inc.
Chemical Signatures of Fossilized Resins and Recent Plant Exudates
Authors: Lambert Joseph B. , Santiago‐Blay Jorge A. , Anderson Ken B.
Published: October 2008

Amber is one of the few gemstones based on an organic structure. Found over most of the world, it is the fossil form of sticky plant exudates called resins. Investigation of amber by modern analytical techniques provides structural information and insight into the identity of the ancient plants that produced the source resin. Mass spectrometric analysis of materials separated by gas chromatography has identified specific compounds that are the basis of a reliable classification of the different types of amber. NMR spectroscopy of bulk, solid amber provides a complementary classification. NMR spectroscopy also can be used to characterize modern resins as well as other types of plant exudates such as gums, gum resins, and kinos, which strongly resemble resins in appearance but have very different molecular constitutions.
Construction of Giant Porphyrin Macrorings Self‐Assembled from Thiophenylene‐Linked Bisporphyrins for Light‐Harvesting Antennae
Authors: Fujisawa Kaori , Satake Akiharu , Hirota Shun , Kobuke Yoshiaki
Published: October 2008

As a model of bacterial photosynthetic light‐harvesting antenna, a large number of porphyrin units were organized into barrel‐shaped macrorings. Two imidazolylporphyrinatozinc(II) molecules were linked through either unsubstituted thiophenes or 3,4‐dioctylthiophenes 1 a and 1 b, respectively. These structures were spontaneously organized by complementary coordination of the imidazolyl to zinc and produced a series of self‐assembled fluorescent polygonal macrorings under high dilution conditions. The ring size increased compared with previous m‐phenylene examples. The size distribution was also controlled by the presence of octyl substituents. A wide distribution of macrorings from 7‐ to >15‐mer was obtained from 1 a, whereas macrorings ranging from 7‐ to 11‐mer with a maximum population focused at the 8‐mer were formed with 1 b. The size distribution was governed by competition between entropy‐favored, smaller‐ring formation and the enthalpy‐favored, less‐strained larger macroring. The UV/Vis spectra showed a gradual redshift for the larger rings reflecting an increase in the transition dipole interactions.
Rapid Ketone Transfer Hydrogenation by Employing Simple, In Situ Prepared Iridium(I) Precatalysts Supported by “Non‐NH” P,N Ligands
Authors: Lundgren Rylan J. , Stradiotto Mark
Published: October 2008

The catalytic utility in ketone transfer hydrogenation (TH) of the preformed complexes [Ir(cod)(κ2‐2‐NMe2‐3‐PiPr2‐indene)]+X− ([2 a]+X−; X: PF6, BF4, and OTf; cod: η4‐1,5‐cyclooctadiene; OTf: trifluoromethanesulfonate), [Ir(cod)(κ2‐1‐PiPr2‐2‐NMe2‐indene)]+OTf− ([2 b]+OTf−), [Ir(cod)(κ2‐2‐NMe2‐3‐PiPr2‐indenide)] (3), and [Ir(cod)(κ2‐o‐tBu2P‐C6H4‐NMe2)]+PF6− ([4]+PF6−), as well as of related mixtures prepared from [{IrCl(cod)}2] and various P,N‐substituted indene or phenylene ligands, was examined. Whereas [2 a]+X−, [2 b]+OTf−, 3, and related in situ prepared Ir catalysts derived from P,N‐indenes proved to be generally effective in mediating the reduction of acetophenone to 1‐phenylethanol in basic iPrOH at reflux (0.1 mol % Ir; 81–99 % conversion) in a preliminary catalytic survey, the structurally related Ir catalysts prepared from (o‐R2P‐C6H4)NMe2 (R: Ph, iPr, or tBu) were observed to outperform the corresponding P,N‐indene ligands under similar conditions. In the course of such studies, it was observed that alteration of the substituents at the donor fragments of the supporting P,N ligand had a pronounced influence on the catalytic performance of the derived catalysts, with ligands featuring bulky dialkylphosphino donors proving to be the most effective. Notably, the crystallographically characterized complex [4]+PF6−, either preformed or prepared in situ from a mixture of [{IrCl(cod)}2], NaPF6, and (o‐tBu2P‐C6H4)NMe2, proved to be highly effective in mediating the catalytic transfer hydrogenation (TH) of ketones in basic iPrOH, with near quantitative conversions for a range of alkyl and/or aryl ketones and with very high turnover‐frequency values (up to 230 000 h−1 at >50 % conversion); this thereby enabled the use of Ir loadings ranging from 0.1 to 0.004 mol %. Catalyst mixtures prepared from [{IrCl(cod)}2], NaPF6, and the chiral (αS,αS)‐1,1′‐bis[α‐(dimethylamino)benzyl]‐(R,R)‐2,2′‐bis(dicyclohexylphosphino)ferrocene (Cy‐Mandyphos) ligand proved capable of mediating the asymmetric TH of aryl alkyl ketones, including that of the hindered substrate 2,2‐dimethylpropiophenone with an efficiency (0.5 mol % Ir; 95 % conversion, 95 % ee) not documented previously in TH chemistry.

Effect of Osmolytes on Pressure‐Induced Unfolding of Proteins: A High‐Pressure SAXS Study
Authors: Krywka Christina , Sternemann Christian , Paulus Michael , Tolan Metin , Royer Catherine , Winter Roland
Published: October 2008

Herein, we explore the effect of different types of osmolytes on the high‐pressure stability and tertiary structure of a well‐characterized monomeric protein, staphylococcal nuclease (SNase). Changes in the denaturation pressure and the radius of gyration are obtained in the presence of different concentrations of trimethylamine N‐oxide (TMAO), glycerol and urea. To reveal structural changes in the protein upon compression at various osmolyte conditions, small‐angle X‐ray scattering (SAXS) experiments were carried out. To this end, a new high‐pressure cell suitable for high‐precision SAXS studies at synchrotron sources was built, which allows one to carry out scattering experiments up to maximum pressures of about 7 kbar. Our data clearly indicate that the osmolytes that stabilize proteins against temperature‐induced unfolding drastically increase their pressure stability and that the elliptically shaped curve of the pressure–temperature–stability diagram of proteins is shifted to higher temperatures and pressures with increasing osmolyte concentration. A drastic stabilization is observed for the osmolyte TMAO, which exhibits not only a significant stabilization against temperature‐induced unfolding, but also a particularly strong stabilization of the protein against pressure. In fact, such findings are in accordance with in vivo studies (for example P. J. Yancey, J. Exp. Biol. 2005, 208, 2819–2830), where unusually high TMAO concentrations in some deep‐sea animals were found. Conversely, chaotropic agents such as urea have a strong destabilizing effect on both the temperature and pressure stability of the protein. Our data also indicate that sufficiently high TMAO concentrations might be able to largely offset the destabilizing effect of urea. The different scenarios observed are discussed in the context of recent experimental and theoretical studies.
