Full textPlanktonic foraminifera contribute to the marine biological carbon pump by generating organic (cytoplasm) and inorganic (shell) carbon fluxes. In this study, we characterized LPF total abundances, assemblages and test morphometry (minimum diameter) along 19 stations sampled by stratified plankton net (Multinet), during three consecutive austral summers (2012-2014) in the Southern Indian Ocean (30°S-60°S, 50°E-80°E). By demonstrating the efficiency of CPR for LPF sampling, we analysed population dynamic between 19 multinet sampling stations, showing the effect of frontal position on LPF production. To better constrain the impact of those organisms in the biological carbon pump at high latitudes, we have quantified the individual protein-biomass and test calcite mass of more than 2000 LPF. Differences in size-normalized protein-biomass and in size-normalized weight between years, species, and water bodies suggest that environmental parameters affect the production of planktonic foraminifera organic and inorganic carbon to varying degrees. Consequently, planktonic foraminifera are assumed to affect the biological carbon pump, depending on ecological conditions and biological prerequisites. The applicability of planktonic foraminifera tests as proxy of the past biological carbon pump in high latitudes would hence critically depend on the effect exerted by changing in ecological conditions, and the presence of different species. This study proposes a first estimation of planktonic foraminifera Corg and Cinorg standing stock and fluxes in the Southern Indian Ocean

Full textThe objective of this thesis was to assess the biogeochemical effect of two forcings: the ocean acidification and the dust deposition. Firstly, we showed that in the Low Nutrient Low Chlorophyll (LNLC) area the effect of the ocean acidification on the marine cycle of nitrogen (N), phosphorus (P) and iron (Fe) will be likely negligible. The pH decrease of the surface waters depleted in N and P would not affect the speciation of these elements, and the absence of effect on the composition of the plankton community would not lead to a shift in the dynamic of inorganic nutrients. Secondly, the experiments performed during this thesis allowed a better parametrization of the post-depositional processes of atmospheric nutrients in the surface seawater after a Saharan event. The exchanges dissolved/particulate occurred in the short timescale. They were controlled by both the particles dynamic and the nature of the dissolved organic matter (DOM) that can aggregate with the lithogenic particles. Under ocean acidification conditions, while the dissolution of anthropogenic elements adsorbed onto dust, such as the inorganic nitrogen, will not be affected, the dissolution of the crustal elements (P and Fe) could be higher and faster according the formation of organic-dust aggregates. The major role of the aggregation process on the availability of atmospheric nutrients was highlighted by the rapid and large abiotic formation of transparent exopolymeric particles (TEP) following the dust deposition to the surface waters

Full textThe biological carbon pump transfers CO2 from the atmosphere to the deep ocean as particulate organic matter. By forming aggregates, diatoms contribute strongly to the particle flux.Copepods, in terms of abundance and diversity, dominate zooplankton assemblages, are the main consumers of diatoms and play and key role in the carbon export via faecal pellets egestion. Nutrient limitations mainly occur at the end of phytoplankton blooms, but are also an expected consequence of global warming. The aim of the thesis is to evaluate the role of copepod/diatom interactions on carbon export in a context of climate change.The results obtained show that nutrient limitations affecting diatoms biochemical composition, that influences copepods feeding activity and the export efficiency of faecal pellets. I have also shown that the functional traits of copepods can influence both the aggregates formation and their dynamics. Finally, using data from an oceanographic campaign carried out during the Arctic phytoplankton spring bloom, I observed that silicon limitation after sea ice retreat contributes to the aggregates formation. Copepods, at the end of the bloom migrate under the mixing layer where the aggregates are most abundant, which may suggest that the aggregates could be used as a food
Arantxa, Camus Etchecopar. "Mécanismes moléculaires impliqués dans la formation de biofilm à l’interface eau-composés organiques hydrophobes." Thesis, Pau, 2014. http://www.theses.fr/2014PAUU3032/document.
Full textHydrophobic organic compounds (HOC), a large family of naturally-produced or anthropogenic molecules including lipids and hydrocarbons, represent a significant part of organic matter in marine ecosystems. Because of their low solubility in water, bacteria that degrade those compounds require the establishment of specific cell functions to increase their biodisponibility. Biofilm formation in water-HOC interface is one of these adaptations. The model of bacteria used in our laboratory, Marinobacter hydrocarbonoclasticus SP17, is able to form a biofilm on a wide range of HOC, such as alkanes, fatty alcohols and triglycerides, in order to use them as a carbon and energy source. The main purpose of my work was to broaden the knowledge of how bacteria adhere to and from biofilms on HOC, through the functional characterization of 10 candidate genes highlighted during proteomic and transcriptomic studies. Genetic tools and a gene-specific functional characterization have been developed in order to carry out this project. Functional study conducted on MARHY2686 revealed its involvement in the formation of biofilm on alkanes. Co-expression of MARHY2686 and the adjacent genes MARHY2687 and MARHY2685 durnig transcriptomic analysis together with their phylogenetic distribution and synteny conservation suggest that these three genes are involved in the same biological process. According to the high peptide sequence identity between MARHY2686 and AdeT, a periplasmic protein of a tripartite efflux pump system of Acinetobacter baumanii, MARHY2686 in combination with MARHY2687 and MARHY2685 could be the components of such a system. Other phenotypic observations would consider the involvement of MARHY2686 either in the assimilation of HOC or in the accumulation of intracellular lipid reserves. M. hydrocarbonoclasticus SP17 uses type IV pili during biofilm formation on HOC. These appendages are involved in the adhesion of this strain to and in a detachment process from HOC. Type IV pili could either act directly to allow bacteria to detach from the surface to which it is adhered, or indirectly through the action of bacteriophages. The presence of twitching motility on HOC has also been suggested. Finally, the role of the type VI secretion system (T6SS), a well-known protein system which allows interactions between bacteria and host cells, during the formation of a mono-species biofilm on HOC where no other microorganism than M. hydrocarbonoclasticus SP17 is present, has been studied

Full textThis work is part of the OUTPACE project which aimed to characterize the western tropical south Pacific (WTSP) in terms of biogeochemical stocks and fluxes and biological diversity of diazotrophs along a West-East longitudinal transect. This work combines an experimental with a modeling approach in order to study the role of diazotrophy in the planktonic dynamics and biogeochemical cycles of the WTSP surface waters. The values measured during the campaign, iespecially those of primary production (PP) and dissolved inorganic phosphate (DIP) turnover time, revealed a West-East gradient of productivity and nutrient availability, closely related to the spatial variability of N$_2$ fixation rates. The use of a mechanistic biogeochemical model (implemented in the Eco3M platform) explicitly including two compartments of diazotrophs and coupled with a vertical 1D physical model, allowed to highlight the fact that the absence / presence of diazotrophy could explain the contrast between the western regions of the Melanesian Archipelago (WMA) and the west of the south Pacific gyre (WGY). ). The model results showed that non-diazotrophic organisms benefited from the new nitrogen supply provided by nitrogen fixers, and that the surface planktonic production depended significantly on diazotroph activity, which is controlled by the phosphate availability in the west and by the iron availability in the east of the WTSP

Full textThis work is part of the SIMED project which is dedicated to basin-scale modeling of the Mediterranean Sea. It also belongs to the MERMEX program which aims at studying biogeochemical cycles in the Mediterranean Sea and their evolution. The first step of this work was to couple the hydrodynamic modeling platform (NEMO) to the mechanistic biogeochemical modeling platform (Eco3M). We ran a simulation (2000-2012) using the hydrodynamic outputs from NEMO-MED12 configuration to force the biogeochamical model Eco3M-MED. The model evaluation was conducted using numerous field measurements (chlorophyll, nutrients, primary production, etc.). The simulation strengthens and extends to the whole basin the prominent role of dissolved organic carbon in the biological carbon pump in the whole Mediterranean Sea. A comprehensive analysis of organic carbon (particulate and dissolved) production processes production was performed. Results reveal that particulate organic carbon production is restricted to the highly dynamic areas, whereas dissolved organic carbon accumulation in the surface layers is a common process in much areas of the basin. This latter process appeared to dependant on the cellular contents of phytoplancton and heterotrophic bacteria, themselved being controled by low phosphate availability. Finally, the dissolved organic carbon contribution to carbon export is around 64 % in the Western basin, and up to 90 % in the Eastern basin. When taking into account the dissolved fraction, total organic carbon export in the Eastern basin -despite its higher oligotrophy- exceeds the one in the Western basin (60% against 40 %)
Conway, Betsy Ann. "The effects of laforin, malin, Stbd1, and Ptg deficiencies on heart glycogen levels in Pompe disease mouse models." Thesis, 2015. http://hdl.handle.net/1805/7979.
Full textPompe disease (PD) is a rare metabolic myopathy characterized by loss of acid alpha-glucosidase (GAA), the enzyme responsible for breaking down glycogen to glucose within the lysosomes. PD cells accumulate massive quantities of glycogen within their lysosomes, and as such, PD is classified as a “lysosomal storage disease” (LSD). GAA-deficient cells also exhibit accumulation of autophagic debris. Symptoms of severe infantile PD include extreme muscle weakness, hypotonia, and hypertrophic cardiomyopathy, resulting in death before one year of age. Certain LSDs are currently being successfully treated with enzyme replacement therapy (ERT), which involves intravenous infusion of a recombinant enzyme to counteract the endogenous deficiency. ERT has been less successful in PD, however, due to ineffective delivery of the recombinant enzyme. Alternatively, specific genes deletion may reduce lysosomal glycogen load, and could thus be targeted in PD therapy development. Absence of malin (EPM2B) or laforin (EPM2A) has been proposed to impair autophagy, which could reduce lysosomal glycogen levels. Additionally, deficiency of Stbd1 has been postulated to disable lysosomal glycogen import. Furthermore, Ptg deficiency was previously reported to abrogate Lafora body formation and correct neurological abnormalities in Lafora disease mouse models and could have similar effects on PD pathologies. The goal of this study was to characterize the effects of homozygous disruption of Epm2a, Epm2b, Stbd1, and Ptg loci on total glycogen levels in PD mouse model heart tissue, as in severe infantile PD, it is accumulation of glycogen in the heart that results in fatal hypertrophic cardiomyopathy. Gaa-/- mice were intercrossed with Epm2a-/-, Epm2b-/-, Stbd1-/-, and Ptg-/- mice to generate wildtype (WT), single knockout, and double knockout mice. The results indicated that Gaa-/- hearts accumulated up to 100-fold more glycogen than the WT. These mice also displayed cardiac hypertrophy. However, deficiency of Epm2a, Epm2b, Stbd1, or PTG in the Gaa-/- background did not reveal changes of statistical significance in either heart glycogen or cardiac hypertrophy. Nevertheless, since total glycogen was measured, these deficiencies should not be discarded in future discussions of PD therapy, as increasing sample sizes and/or distinguishing cytosolic from lysosomal glycogen content may yet reveal differences of greater significance.
