Abstract. High concentrations of organic matter accumulated in marine sediments during Oceanic Anoxic Events (OAEs) in the Cretaceous. Model studies examining these events invariably make use of global ocean circulation models. In this study, a regional model for the North Atlantic Basin during OAE2 at the Cenomanian-Turonian boundary has been developed. A first order check of the results has been performed by comparison with the results of a recent global Cenomanian CCSM3 run, from which boundary and initial conditions were obtained. The regional model is able to maintain tracer patterns and to produce velocity patterns similar to the global model. The sensitivity of the basin tracer and circulation patterns to changes in the geometry of the connections with the global ocean is examined with three experiments with different bathymetries near the sponges. Different geometries turn out to have little effect on tracer distribution, but do affect circulation and upwelling patterns. The regional model is also used to test the hypothesis that ocean circulation may have been behind the deposition of black shales during OAEs. Three scenarios are tested which are thought to represent pre-OAE, OAE and post-OAE situations. Model results confirm that Pacific intermediate inflow together with coastal upwelling could have enhanced primary production during OAE2. A low sea level in the pre-OAE scenario could have inhibited large scale black shale formation, as could have the opening of the Equatorial Atlantic Seaway in the post-OAE scenario.

Abstract:
AbstractOceanic anoxic events (OAEs) are contemporaneous with 11 of the 18 largest Phanerozoic extinction events, but the magnitude and selectivity of their paleoecological impact remains disputed. OAEs are associated with abrupt, rapid warming and increased CO2flux to the atmosphere; thus, insights from this study may clarify the impact of current anthropogenic climate change on the biosphere. We investigated the influence of the Late Cretaceous Bonarelli event (OAE2; Cenomanian/Turonian stage boundary; ~94 Ma) on generic- and species-level molluscan diversity, extinction rates, and ecological turnover. Cenomanian/Turonian results were compared with changes across all Cretaceous stage boundaries, some of which are coincident with less severe OAEs. We found increased generic turnover, but not species-level turnover, associated with several Cretaceous OAEs. The absence of a species-level pattern may reflect species occurrence data that are too temporally coarse to robustly detect patterns. Five hypotheses of ecological selectivity relating anoxia to survivorship were tested across stage boundaries with respect to faunality, mobility, and diet using generalized linear models. Interestingly, benthic taxa were consistently selected against throughout the Cretaceous regardless of the presence or absence of OAEs. These results suggest that: (1) the Cenomanian/Turonian boundary (OAE2) was associated with a decline in molluscan diversity and increase in extinction rate that were significantly more severe than Cretaceous background levels; and (2) no differential ecological selectivity was associated with OAE-related diversity declines among the variables tested here.

Objectives: To find out the incidence of hearing impairment in Neonatal Intensive Care Unit (NICU)-admitted newborns and to correlate between several risk factors. Design: Prospective observational study. Setting: In a tertiary teaching hospital of Odisha between October 2014 and October 2016. Study population: 100 newborns delivered in the institution and admitted in NICU with usual indications and risk factors that underwent otoacoustic emission 1 and 2 (OAE1, OAE2) and Brainstem Evoked Response Audiometry (BERA). Results: 84 babies in OAE1 and 86 babies in OAE2 got “pass” results. In BERA test, 92 babies got normal waveform. 7 (13.7%) of 51 premature babies, 5 (38.5%) of 13 very low birth weight babies, 7 (17.5%) of 40 babies receiving ototoxic medication for >5 days, 7 (31.8%) of 22 babies with hyperbilirubinemia, 6 (42.9%) of 14 babies with sepsis, 5 (20%) of 20 babies with birth asphyxia, 3 (60%) of 5 babies under mechanical ventilation for >5 days, 1 baby with ear abnormality, and 1 (50%) out of 2 babies with congenital infections had hearing impairment and statistically significant association with abnormal OAE and BERA test. Conclusion: There is high incidence of hearing loss in NICU-admitted newborns. OAE and BERA both should be performed for complete evaluation of hearing. Important risk factors are elaborated. Predischarge hearing assessment in NICU is most important.

Abstract:
In the present paper we examine the use of carbon and oxygen stable isotopes in the study of global palaeoceanographic changes, with special reference to the oceanic anoxic events (OAEs). The analysis of stable isotopes was applied to the examination of Cretaceous sediments from the Ionian and Pindos zones of Western Greece. In the Ionian zone the carbon and oxygen stable isotopes, combined with biostratigraphic data, record the palaeoenvironmental change corresponding to the anoxic events Bonarelli (Cenomanian/Turonian, OAE2) and Paquier (Lower Albian, OAE1b). In the Pindos zone, within the Cretaceous sediments, we observed two organic-carbon-rich levels. According to the biostratigraphic and isotopie analysis, the first level corresponds to an OAE of Santonian age. This local oceanic anoxic event is described for the first time. The second level, Aptian - Albian age, possibly correlates to either the Paquier event (OAE 1b) or the Selli event (OAE 1a), which in Greece were until now known only in the Ionian zone.

Abstract:
The true power of otoacoustic emissions (OAEs) continues to be explored. OAE spectral characteristics are typically studied in research and applied in the clinic. However, OAE temporal aspects are relatively underexplored. Not using temporal features is similar to ignoring nearly half of the information that OAEs provide. Besides providing information related to the generation of OAEs and cochlear mechanics, the temporal characteristics have important clinical implications, such as for assessing frequency selectivity, characterizing the strength of the efferent auditory system. This review provides a general synopsis of the fundamental principles of OAE delay and latency and discusses some of the relevant applications in probing the strength of the efferent neural pathway and frequency selectivity. It is expected that the reader will gain an overview of the implications of the latency or phase behavior of OAEs.

Abstract:
Abstract. Oceanic anoxic events (OAEs) document major perturbations of the global carbon cycle with repercussions for the Earth's climate and ocean circulation that are relevant to understanding future climate trends. Here, we compare the onset and development of Cretaceous OAE1a and OAE2 in two drill cores with unusually high sedimentation rates from the Vocontian Basin (southern France) and Tarfaya Basin (southern Morocco). OAE1a and OAE2 exhibit remarkable similarities in the evolution of their carbon isotope (δ13C) records, with long-lasting negative excursions preceding the onset of the main positive excursions, supporting the view that both OAEs were triggered by massive emissions of volcanic CO2 into the atmosphere. However, there are substantial differences, notably in the durations of individual phases within the δ13C positive excursions of both OAEs. Based on analysis of cyclic sediment variations, we estimate the duration of individual phases within OAE1a and OAE2. We identify (1) a precursor phase (negative excursion) lasting ∼430 kyr for OAE1a and ∼130 kyr for OAE2, (2) an onset phase of ∼390 and ∼70 kyr, (3) a peak phase of ∼600 and ∼90 kyr, (4) a plateau phase of ∼1340 and ∼200 kyr, and (5) a recovery phase of ∼380 and ∼440 kyr. The total duration of the positive δ13C excursion is estimated at 2700 kyr for OAE1a and 790 kyr for OAE2, and that of the main carbon accumulation phase is estimated at 980 and 180 kyr. The long-lasting peak, plateau and recovery phases imply fundamental changes in global nutrient cycles either (1) by submarine basalt–seawater interactions, (2) through excess nutrient inputs to the oceans by increasing continental weathering and river discharge, or (3) through nutrient recycling from the marine sediment reservoir. We investigated the role of phosphorus in the development of carbon accumulation by analysing phosphorus speciation across OAE2 and the mid-Cenomanian Event (MCE) in the Tarfaya Basin. The ratios of organic carbon and total nitrogen to reactive phosphorus (Corg∕Preact and Ntotal∕Preact) prior to OAE2 and the MCE hover close to or below the Redfield ratio characteristic of marine organic matter. Decreases in reactive phosphorus resulting in Corg∕Preact and Ntotal∕Preact above the Redfield ratio during the later phase of OAE2 and the MCE indicate leakage from the sedimentary column into the water column under the influence of intensified and expanded oxygen minimum zones. These results suggest that a positive feedback loop, rooted in the benthic phosphorus cycle, contributed to increased marine productivity and carbon burial over an extended period of time during OAEs.

Abstract:
BackgroundTime-frequency distributions can help reveal resonant modes of OAEs. The Husimi transform is the time-frequency distribution of probability. The sound pressure probability density function for a given frequency can be derived from the Husimi transform. Using the Husimi transform as the weight function, it is possible to define the spectral kurtosis of OAEs.Material and MethodsThe Husimi transform was calculated numerically from OAE data recorded from subjects with normal hearing. We examined click-evoked OAEs (CEOAEs) and tone-burst-evoked OAEs (TBOAEs) with stimuli centered at 1, 2, and 4 kHz, and the presence of spontaneous OAEs (SOAEs) was also investigated. The aim of this study was to examine the statistical properties of otoacoustic emissions (OAEs) and relate them to resonant modes of the cochlea. Assuming that the probability of the sound pressure of an OAE at any time and frequency is given by a Husimi-type transform, we analyzed statistical features of the probability distribution, particularly spectral kurtosis.ResultsWith evoked OAEs, a minimum in kurtosis was found at frequencies close to SOAEs. With TBOAEs, three sorts of SOAEs were found: those with high positive kurtosis, those with small positive kurtosis, and those with negative kurtosis; in these cases, SOAEs appeared at the same frequency as the kurtosis minimum.ConclusionsThe kurtosis of evoked components of an OAE is strongly affected by the presence of an SOAE. The number of positive peaks and negative troughs of spectral kurtosis in a given frequency band seem to be characteristic of each subject. It is suggested that a new way of distinguishing types of OAEs may involve calculating the spectral kurtosis, and this may be diagnostically useful.

Abstract:
Il Cretacico si caratterizza per la presenza di diversi intervalli di alterazione del sistema climatico-oceanico a scala globale responsabili della deposizione di black-shale marini ricchi di carbonio, definiti come Eventi Anossici Oceanici (OAEs). L’OAE3 rappresenta l’ultimo episodio di diffusa anossia durante l’intervallo Coniaciano-Santoniano. Rispetto ai precedenti eventi anossici, l’OAE3 ha una estensione regionale, ma non globale, poiché risulta essere confinato all’Oceano Atlantico sud-equatoriale e ad alcuni bacini limitrofi (es: Bacino Caraibico, Bacino del Western Interior). Altre importanti differenze fra l’OAE3 e i precedenti eventi anossici consistono nell’assenza di una anomalia del δ13C, ma piuttosto il verificarsi durante il Coniaciano-Santoniano di una serie di escursioni isotopiche sia positive che negative di piccola entità. Inoltre la deposizione di sedimenti ricchi di materia organica (black shales) sembra essere diacrona anche all’interno dello stesso Atlantico centro-meridionale. I principali obiettivi di questa tesi sono la ricostruzione di eventuali cambiamenti paleoceanografici avvenuti durante l’OAE3 in base alle variazioni di abbondanza e composizione delle associazioni a nannofossili calcarei. Il mio progetto di dottorato si è concentrato sulla biostratigrafia e paleoceanografia a nannofossili calcarei per l’intervallo compreso tra il tardo Turoniano e il Campaniano inferiore (Cretacico Superiore) e in particolare sul Coniaciano-Santoniano. La studio delle associazioni a nannofossili calcarei sia in termini semiquantitativi che quantitativi ha permesso di ottenere una biostratigrafia di dettaglio utile a datare e correlare le variazioni del nannoplancton calcareo durante l’OAE3. Lo studio è stato condotto sia su siti oceanici carotati nell’ambito dei progetti Deep Sea Drilling Project (DSDP) e Ocean Drilling Program (ODP) che su sezioni continentali, situate nell’Atlantico sud-equatoriale, in Oceano Indiano e nel Bacino Anglo-Parigino. I risultati ottenuti sono stati poi integrati con dati di letteratura al fine di ottenere una successione di eventi per il Coniaciano-Santoniano e fornire una caratterizzazione paleoceanografica dell’OAE3. È stata realizzata una dettagliata revisione tassonomica per risolvere alcune incongruenze tassonomiche e ottenere una terminologia aggiornata e unificata. Questa è stata la base per una biostratigrafia coerente, ad alta risoluzione delle successioni studiate, e stabilire una datazione e correlazione a scala sovra-regionale. Sono state applicate le quattro biozonazioni standard proposte per il Cretacico Superiore per ottenere la massima risoluzione e testare la loro applicabilità nei diversi bacini e contesti oceanografici. Le analisi quantitative delle associazioni a nannofossili calcarei hanno permesso di caratterizzare la distribuzione dei nutrienti prima, durante e dopo l’OAE3. La distribuzione dei taxa indicativi di più alta fertilità mostra caratteristiche diverse per le varie successioni, suggerendo che l’OAE3 non è stato caratterizzato da un episodio globale di fertilizzazione. Infatti, la fertilità rimane in genere bassa ad eccezione delle aree di upwelling che sono caratterizzate da condizioni meso-eutrofiche anche negli intervalli che precedono e seguono l’OAE3. Le analisi quantitative condotte in questo studio hanno evidenziato la presenza di ampie fluttuazioni di abbondanza dei generi Micula e Marthasterites durante il Coniaciano-Santoniano. Questi picchi di abbondanza possono essere correlati con eventi analoghi descritti in letteratura, anche se con valori di incremento differenti nei vari siti. Durante l’OAE3 sono stati individuati due distinti picchi di abbondanza di Marthasterites (M. furcatus) e cinque di Micula (M. staurophora). L’affinità paleoecologica di Micula, e in particolare M. staurophora, così come quella del genere Marthasterites rimane poco chiara, pertanto le cause dei loro picchi di abbondanza devono essere individuate. Tuttavia, le fluttuazioni nelle associazioni a nannofossili calcarei indicano un profondo cambiamento paleoceanografico durante il Coniaciano-Santoniano. L’inizio dell’OAE3 coincide con un elevato aumento in abbondanza (e localmente dominanza) di M. furcatus, che suggerisce il rapido instaurarsi di nuove e peculiari condizioni paleoceanografiche ad ampia scala. Le condizioni paleoceanografiche più alterate sono raggiunte nella parte centrale dell’OAE3 con un picco di abbondanza (climax) di M. staurophora sincrono a scala globale. Oltre al loro valore per le ricostruzioni paleoambientali, i picchi di abbondanza di Micula and Marthasterites si sono rilevati estremamente utili per complementare/implementare la caratterizzazione biostratigrafica dei limiti Turoniano/Coniaciano, Coniaciano/Santoniano e Santoniano/Campaniano. Questi picchi di abbondanza potrebbero dunque essere introdotti come eventi addizionali in future zonazioni a nannofossili calcarei del Cretacico Superiore.
The Late Cretaceous was punctuated by several periods of global perturbations of the climate-ocean system that lead to widespread organic carbon-rich marine black shale deposition, termed Oceanic Anoxic Events (OAEs). The OAE3 represents the last episode of anoxia dated as Coniacian-Santonian. Compared to previous anoxic events, OAE3 has a regional extension, rather than a global significance, since it is confined to the equatorial-south Atlantic Ocean and adjacent basins (e.g. Caribbean Basin, Western Interior Basin). Another major difference of OAE3 relative to previous OAEs resides in the absence of a prominent δ13C anomaly, but the occurrence of several minor positive and negative excursions in the Coniacian-Santonian interval. Moreover, the deposition of organic carbon-rich sediments (black shales) seems to be diachronous even in the central-south Atlantic Ocean. This PhD project focused on calcareous nannofossil biostratigraphy and paleoceanography of the Late Turonian to Early Campanian time interval (Late Cretaceous), and specifically of the Coniacian-Santonian. Nannofossil assemblages were investigated semiquantitatively and quantitatively to obtain a detailed biostratigraphic framework for assessing the paleoenvironmental changes across OAE3. The study was performed on Deep Sea Drilling Project (DSDP) and Ocean Drilling Program (ODP) sites and on-land sections, situated in the equatorial and south Atlantic Ocean, the Indian Ocean and the Anglo-Paris Basin. The results of my investigation were integrated with data from literature in order to achieve a solid framework of events for the Coniacian-Santonian time interval and provide a paleoceanographic characterization of OAE3. A detailed revision of the taxonomy was accomplished for solving a few taxonomic incongruities and obtain a unified updated nomenclature. This was the basis for the coherent high-resolution biostratigraphy of the selected sites, in order to establish dating and correlations at supra-regional scale. The four standards biozonation schemes available for the Upper Cretaceous were applied to attain the maximum resolution and test their individual applicability in different oceanic basins and oceanographic settings. The major objective of this PhD thesis was the reconstruction of presumed paleoceanographic changes across OAE3 as recorded by abundance and composition of calcareous nannofossil assemblages. Quantitative analyses of calcareous nannofossil assemblages allowed the characterization of paleotemperature and nutrient changes prior, during and after OAE3. Nannofossil-based paleotemperature obtained in this study and documented in the literature do not show significant changes in the studied successions, perhaps due to unresolved unambiguous temperature-related taxa in the Late Cretaceous and/or minor (subtle) temperature changes across OAE3. As far as paleofertility isconcerned, the nannofossil taxa indicative of higher nutrient content display very different patterns at the various sites, suggesting that OAE3 was not characterized by a global fertilization episode. Indeed, fertility remained globally low with the exception of upwelling areas characterized by meso-eutrophic conditions also in the intervals preceding and following OAE3. The quantitative analyses conducted in this study pointed out relatively large fluctuations in abundance of genera Micula and Marthasterites in the Coniacian-Santonian interval. These abundance peaks could be correlated with analogous events described in the literature, even if with different values of abundance at the various sites/sections. Two Marthasterites (M. furcatus) abundance peaks and five Micula (M. staurophora) abundance peaks were distinguished across OAE3. The paleoecological affinity of Micula, and specifically M. staurophora, as well as that of genus Marthasterites remains unexplained, so the causes of their abundance peaks continue to be elusive. However, the distinctive fluctuations in nannofossil assemblages indicate profound paleoceanographic changes during the Coniacian-Santonian. The onset of OAE3 coincides with a major increase in abundance (and locally dominance) of M. furcatus suggesting the rapid establishment of new and peculiar paleoceanographic conditions at widespread to global scale. The most altered paleoceanographic conditions were reached in the core of OAE3 with the synchronous maximum abundance (climax) of M. staurophora at global scale. In addition to their value for paleoenvironmental reconstructions, the identified Micula and Marthasterites abundance peaks turned out to be extremely useful for complementing/implementing the biostratigraphic characterization of the Turonian/Coniacian, Coniacian/Santonian and Santonian/Campanian boundaries and might be introduced as additional events in future nannofossil zonations for the Late Cretaceous.

São apresentados os resultados de uma pesquisa que teve como objetivo propor um modelo de previsão da degradação, baseada numa análise determinística e estocástica, para contribuir no acompanhamento das Obras de Arte Especiais – OAEs do Brasil, sob responsabilidade do Departamento Nacional de Infraestrutura de Transporte – DNIT, e para banco de dados similares. No banco de dados do DNIT consta o inventário de quatro mil quinhentos e trinta e uma OAEs, com uma vistoria realizada entre 2012 a 2016 para todas as obras do inventario. Devido ao número insuficiente de registros históricos para o desenvolvimento de um modelo de previsão da degradação das OAEs, foram testados os modelos de degradação utilizando-se o banco de dados do Departamento de Transporte de Nevada (NDOT), obtido durante um ano de estágio desenvolvido na Universidade de Nevada, Las Vegas (USA). Foi realizado um estudo comparativo dos modelos de degradação, e após a calibragem dos modelos de previsão com o banco de dados de NDOT, foi determinado o modelo de degradação mais apropriado para as OAEs sob responsabilidade do DNIT e banco de dados similares, visando proporcionar apoio na tomada de decisões e garantir um desempenho eficiente das estruturas. Foi determinado que a Regressão de Potência é o método de cálculo mais apropriado para a estimação das curvas de degradação das OAEs no Brasil, sob responsabilidade do DNIT. Podendo-se utilizar esta regressão de maneira individual para cada uma das OAEs, uma vez sejam realizadas mais inspeções nas estruturas.
The objective of this research was to propose a degradation prediction model, based on a deterministic and stochastic analysis, to contribute to the accompaniment of the Brazil Bridges, under the responsibility of the National Department of Transport Infrastructure - DNIT, and other similar databases. In the DNIT database there is an inventory of four thousand five hundred and thirty-one bridges, but only one inspection was carried out between 2012 and 2016. Due to the insufficient number of historical records for the development of a model for predicting the degradation of bridges, the models of degradation were tested using the database of the Department of Transportation of Nevada (NDOT), obtained during a year of internship developed at the University of Nevada, Las Vegas (USA). A comparative study of the degradation models was carried out, and after the calibration of the forecast models with the NDOT database, the most appropriate degradation model was determined for the bridges under the responsibility of DNIT and similar databases, aiming to provide support in decision-making and ensure efficient performance of structures. It was determined that the Power Regression is the most appropriate calculation method for the estimation of the degradation curves of OAEs in Brazil, under the responsibility of DNIT. This regression can be used individually for each of the OAEs, once more inspections are performed on the structures.

La flambée inattendue de fièvre chikungunya dans les îles de l'Océan Indien en 2006 mis en exergue la nécessité de comprendre la pathogénie de cette maladie peu étudiée. La caractérisation moléculaire de plusieurs isolats cliniques collectés sur l'Ile de La Réunion mis en évidence l'émergence du variant viral E1-226V associé à l'adaptation au vecteur Ae. Albopictus. Pour poursuivre cette caractérisation, nous avons produit des outils spécifiques pour la détection du virus CHIK comme une forme soluble de la glycoprotéine d'enveloppe E2 (gp-E2) ainsi que des anticorps monoclonaux murins spécifiques de la gp-E2 du virus. Chez les individus infectés par les alphavirus dont le virus CHIK, l'infection virale est contrôlée par l'IFN-α/β. Qui stimule la production d'un ensemble de molécules antivirales. Nos travaux suggèrent qu'une famille de ces gènes, les 2',5'-Oligoadenylate Synthétases (OAS), joue un rôle primordial dans l'immunité innée anti-arbovirale. Nous avons étudié si l'isoforme OAS3 humaine joue un rôle contre l'infection par le virus CHIK. Les cellules épithéliales humaines surexprimant l'OASS inhibent efficacement la croissance du virus CHIK aussi bien que d'autres alphavirus comme les virus Sindbis et Semliki Forest. Cette activité anti-alphavirale empêche l'accumulation des ARN viraux et des protéines virales. En conclusion, l'activité de la protéine OAS3 représente une importante voie anti-alphavirale par laquelle l'IFN-α/β contrôle l'infection du virus CHIK dans les cellules humaines
Humans infected with chikungunya virus (CHIKV), a member of the Alphavirus genus of the Togaviridae family, typically experience acute illness with incapaciting polyarthralgia. The unexpected outbreak of chikungunya fever in the Indian Ocean islands in 2006 highlights the need to understand this disease pathogenesis not well studied. Several clinical isolates collected in La Reunion Island were characterized at the molecular level. Our study emphasized the emergence of the viral variant E1-226V associated with adaptation to the vector Ae. Albopictus. The production of specific tools for the CHIK virus detection was necessary to pursue this characterization. We produced a soluble form of the envelope E2 glycoprotein (gp-E2) in Drosophila S2 cells, as well as mouse monoclonal antibodies specific of the virus gp-E2. In people infected by alphavirus such as CHIK virus, the viral infection is controlled by IFN-α/βwhich stimulates the production of a set of antiviral molecules. Our laboratory had shown that the 2', 5'-Oligoadenylate Synthetases (OAS) genes, inducible by IFN-α, play a critical role in antiviral immunity against arboviruses. Whether the OAS3 human form may play a role in the protective innate immunity to CHIKV was investigated. Human epithelial cells respond to ectopic OAS3 protein expression by inhibiting CHIKV growth as efficiently as that of other alphaviruses such as Sindbis and Semliki Forest viruses. The OAS-mediated inhibition of CHIKV growth was attributable to a dramatic reduction in viral RNA and protein levels. In conclusion, OAS3 activity represents an important antialphaviral pathway by which IFN-α/β controls CHIKV infection in human cells

Abstract:
La Chondrodonta, un bivalve simil-ostreide e opportunista, è comunemente riportata nelle piattaforme carbonatiche Tetidee del Cretaceo, con una particolare concentrazione nel periodo Aptiano – Cenomaniano. Nonostante ciò, non è ancora emersa una chiara relazione né temporale né causale tra la proliferazione di questo bivalve e gli Eventi Anossici Oceanici (OAEs). Per tali ragioni, la distribuzione stratigrafica e il significato paleoecologico della Chondrodonta sono stati analizzati ai fini di stabilire un preciso rapporto temporale tra i suoi accumuli e gli OAEs e di definire le possibili perturbazioni ambientali alla base della sua proliferazione. Gli accumuli di Chondrodonta analizzati affiorano nelle successioni carbonatiche di piattaforma interna della Piattaforma Apula (Aptiano inferiore, a ridosso dell’OAE1a), e della Piattaforma Adriatica (Cenomaniano superiore, a ridosso dell’OAE2). Il contesto stratigrafico intorno agli accumuli è stato ricostruito attraverso analisi bio- e chemostratigrafiche. Analisi sedimentologico-litostratigrafiche e geochimiche (concentrazione di elementi maggiori, in traccia e di Terre Rare) hanno permesso di dedurre le variazioni paleo-ambientali associate alla proliferazione del bivalve. Sulla base della correlazione dei record isotopici tra piattaforma e bacino, si è osservato come gli accumuli di Chondrodonta ricadano al di sotto delle tipiche escursioni nella curva del δ13C che segnano, rispettivamente, l’inizio dell’OAE1a e dell’OAE2. In entrambe le successioni studiate, la Chondrodonta appare subordinata all’interno dei calcari a rudiste e raggiunge una fase di massima proliferazione e predominanza sulle stesse rudiste in prossimità dell’inizio degli eventi anossici. Dalle analisi stratigrafiche e geochimiche è emerso come gli intervalli di proliferazione di Chondrodonta siano caratterizzati da un aumento di nutrienti oltre la soglia di tollerabilità per le rudiste, e da fluttuazioni nell’ossigenazione e nell’apporto terrigeno in acque di bassa energia. Gli intervalli a Chondrodonta sono stati correlati anche ad una crescente fertilità e ad un progressivo deterioramento ambientale nelle vicine aree bacinali. La posizione stratigrafica degli accumuli globali di Chondrodonta precede l’inizio degli OAE1a e 2 in piattaforme carbonatiche poste a differenti latitudini e condizioni climatiche, permettendo di considerare la proliferazione di questo bivalve come un bioevento a scala regionale. La proliferazione di Chondrodonta risulta quindi inseribile all’interno di una “finestra ambientale”, innescata dai cambiamenti climatici che preludono gli OAEs e principalmente caratterizzata da un aumento di nutrienti sulle piattaforme carbonatiche. Il bivalve opportunista Chondrodonta beneficia, infatti, della transizione da condizioni oligotrofiche a mesotrofiche in piattaforma, occupando una nicchia ecologica posta al passaggio tra comunità stenotopiche ed euritopiche. La presenza e la durata della “finestra ambientale” sono controllate anche da condizioni paleo-geografiche e idrodinamiche locali così come da locali fluttuazioni nell’ossigenazione delle acque e negli apporti terrigeni. L’eccessivo deterioramento delle condizioni ambientali all’inizio degli OAEs inibisce, per contro, la proliferazione della Chondrodonta provocando la sua scomparsa dalla comunità bentonica in favore di specie propriamente mesotrofiche come dimostrato per la Chondrodonta dell’Aptiano inferiore all’inizio dell’OAE1a. La proliferazione della Chondrodonta rappresenta, quindi, un marker stratigrafico a scala regionale del crescente stress ambientale in piattaforma. La predominanza transitoria della Chondrodonta all’interno della comunità bentonica costituisce la risposta biologica dei sistemi carbonatici di acque basse al crescente deterioramento ambientale che culmina con gli Eventi Anossici Oceanici 1a e 2 del Cretaceo.
The opportunistic, oyster-like bivalve Chondrodonta, common in Tethyan Cretaceous shallow-water carbonates, shows peaks of concentration during the Aptian – Cenomanian time interval. Despite this, neither a temporal nor a causal relationship between the flourishing of this bivalve and Oceanic Anoxic Events (OAEs) has emerged yet. The stratigraphic distribution and the ecological significance of Chondrodonta have been analyzed to both define the timing between its accumulations and OAEs and infer OAE-related environmental perturbations triggering its proliferation. The studied Chondrodonta accumulations occur in inner platform limestones of the lower Aptian Apulia Carbonate Platform straddling OAE1a, and of the upper Cenomanian Adriatic Carbonate Platform straddling OAE2. The stratigraphic framework around the Chondrodonta beds has been built using biostratigraphic and chemostratigraphic data. Palaeoenvironmental changes associated with its proliferation have been inferred by coupling sedimentologic-lithostratigraphic analyses with the concentration of major, trace elements and REE. Based on platform-to-basin stratigraphic correlations, the lower Aptian Chondrodonta beds occur right below the negative δ13C excursion marking the onset of OAE1a and the upper Cenomanian beds occur below the δ13C positive excursion of the OAE2 interval. In both cases, Chondrodonta appears in the stratigraphic succession associated with rudist limestones and then reaches a phase of maximum proliferation and predominance over rudists at the prelude of OAEs. As emerged by stratigraphic and geochemical analyses, the Chondrodonta proliferation occurred in an interval of increasing nutrients and in low-energy seawaters with fluctuating oxygenation and intermittent terrigenous inputs. These environmental changes prevented the settlement of the less tolerant rudists while they promoted the thriving of Chondrodonta in monospecific (or quasi-) benthic communities close to the onset of OAEs. The intervals of Chondrodonta proliferation also correlate to increasing fertility and environmental deterioration in the nearby basins. Further, the stratigraphic position of lower Aptian and upper Cenomanian Chondrodonta accumulations in worldwide carbonate platforms located at different palaeolatitudes and climates, generally predates the onset of OAEs and enables to consider the proliferation of this bivalve as a regional bioevent. Accordingly, the flourishing of Chondrodonta is ascribable within an environmental “window”, triggered by the changing climate preluding OAEs and mainly resulted in nutrient pulses on the platforms top. The opportunistic behavior of Chondrodonta was rather efficient in the transition from oligo- to mesotrophic conditions in shallow-water carbonate areas. This oyster-like bivalve benefitted from this environmental instability and occupied a short-lived environmental niche between more stable, stenotopic and eurytopic benthic communities. The occurrence and duration of this environmental “window” were also controlled by local, quick fluctuations in other seawater parameters (e.g., oxygenation, terrigenous inputs) and by limiting environmental factors related to palaeogeography and hydrodynamics. However, further increase of inhospitable conditions leading to OAEs inhibited the proliferation of the bivalve, allowing fully mesotrophic taxa to dominate the benthic community. This is particularly demonstrated for the early Aptian Chondrodonta, abruptly outpaced by mesotrophic assemblages at the onset of OAE1a. The proliferation of Chondrodonta can be, therefore, used as a regional stratigraphic marker for an early phase of environmental stress in shallow-water carbonate platforms. Its transitionary predominance within the benthic community represents the biotic response of the Cretaceous shallow-water carbonate systems to increasing environmental deterioration peaking with Oceanic Anoxic Events 1a and 2.

The sheep production has been growing surprinsingly in the last years in Brazil, but in despite of this, it can not be considered competitive yet, principally because the lack of structure and organization of the sector. Among the problems faced by the Brazilian sheep producers we could cite the gastrointestinal parasites and the relatively low productivity of the native breeds when compared with the exotic ones. The knowledge of the genetic factors controlling these traits can help in the improvement of then without impair the correlated traits. Through molecular biology and statistical technics is possible to identify genes/chromosomal regions associated with these traits and once the region is confirmed as really important in the control of the characteristic this information could be used in breeding programs through marker assisted selection. Many regions were identified as candidate for growth and nematode resistance traits in sheep and other ruminants, and among of them is the Q arm of the sheep chromosome OAR3. Because of this, the aim of this study was to investigate three microssatelite markers located in the Q arm of the OAR3 and its relationship with growth and nematode resistance traits in sheep from three genetic groups: Santa Inês X Santa Inês, Dorper X Santa Inês e Suffolk X Santa Inês. The association analysis revealed two alleles of the BL4 marker with significative effect in the Santa Inês x Santa Inês genetic group and one allele form the same marker with significative effect in the genetic group Dorper x Santa Inês on birth weight. It was also observed one allele from the BL4 marker associated with slaughter weight in the Santa Inês x Santa Inês genetic group. We did not observe any association between the markers studied and nematode resistance. Our results suggest that there are one or more genes in the studied region related with growth traits, but more studies are required to confirm the importance of this region in the control of these traits and to identificate the candidate genes.
A ovinocultura, apesar de apresentar um crescimento significativo nos últimos anos, ainda não pode ser considerada no Brasil como uma exploração competitiva. Isto se deve principalmente pela falta de organização e estruturação do setor produtivo. Dentre os problemas da ovinocultura nacional podemos citar as parasitoses gastrintestinais e a baixa produtividade das raças locais quando comparadas com raças importadas. O entendimento dos fatores genéticos que controlam as características produtivas pode auxiliar na melhoria dos rebanhos para uma característica importante sem significar prejuízo a outras características. Através de técnicas de biologia molecular e estatística pode-se identificar genes/regiões cromossômicas responsáveis pelo controle dessas características e uma vez que essas regiões sejam identificadas e comprovadas como importantes, essa informação pode ser utilizada em programas de melhoramento genético através de seleção assistida por marcadores. Algumas regiões já foram identificadas como sendo candidatas a conter genes importantes tanto para resistência aos nematódeos gastrintestinais quanto para características de crescimento em ovinos e outras espécies de ruminantes. Dentre estas regiões está o braço Q do cromossomo OAR3 dos ovinos. Por isso, o objetivo deste trabalho foi estudar três marcadores microssatélites localizados no braço Q do cromossomo ovino OAR3 e suas relações com as características de crescimento (peso ao nascimento e peso ao abate) e resistência aos nematódeos gastrintestinais utilizando ovinos pertencentes a três grupos genéticos (Santa Inês X Santa Inês, Dorper X Santa Inês e Suffolk X Santa Inês). A análise de associação revelou a presença de dois alelos do marcador BL4 com efeito significativo no grupo genético Santa Inês x Santa Inês e um alelo do mesmo marcador com efeito significativo no grupo genético Dorper x Santa Inês para peso ao nascimento. Também foi observado efeito de um alelo do marcador BL4 com efeito significativo no grupo genético Santa Inês x Santa Inês para peso ao abate. Não foi observado efeito significativo de nenhum marcador na característica de resistência aos nematódeos gastrintestinais. Os resultados deste trabalho sugerem a presença de um ou mais genes na região estudada para características de crescimento, porém mais estudos são necessários para confirmar a real importância desta região no controle destas características bem como a identificação de possíveis genes candidatos.

Abstract:
We propose the Ornstein auto-encoder (OAE), a representation learning model for correlated data. In many interesting applications, data have nested structures. Examples include the VGGFace and MNIST datasets. We view such data consist of i.i.d. copies of a stationary random process, and seek a latent space representation of the observed sequences. This viewpoint necessitates a distance measure between two random processes. We propose to use Orstein's d-bar distance, a process extension of Wasserstein's distance. We first show that the theorem by Bousquet et al. (2017) for Wasserstein auto-encoders extends to stationary random processes. This result, however, requires both encoder and decoder to map an entire sequence to another. We then show that, when exchangeability within a process, valid for VGGFace and MNIST, is assumed, these maps reduce to univariate ones, resulting in a much simpler, tractable optimization problem. Our experiments show that OAEs successfully separate individual sequences in the latent space, and can generate new variations of unknown, as well as known, identity. The latter has not been possible with other existing methods.

Abstract:
We applied a 1-D plankton ecosystem-biogeochemical model to assess the impacts of ocean alkalinity enhancement (OAE) on seasonal changes in biogeochemistry and plankton dynamics. Depending on deployment scenarios, OAE should theoretically have variable effects on pH and seawater pCO2, which might in turn affect (a) plankton growth conditions and (b) the efficiency of carbon dioxide removal (CDR) via OAE. Thus, a major focus of our work is how different magnitudes and temporal frequencies of OAE might affect seasonal response patterns of net primary productivity (NPP), ecosystem functioning and biogeochemical cycling. With our study we aimed at identifying a parameterization of how magnitude and frequency of OAE affect net growth rates, so that these effects could be employed for Earth System Modell applications. So far we learned that a meaningful response parameterization has to resolve positive and negative anomalies that covary with temporal shifts. As to the intricacy of the response patterns, the derivation of such parameterization is work in progress. However, our study readily provides valuable insights to how OAE can alter plankton dynamics and biogeochemistry. Our modelling study first focuses at a local site where time series data are available (European Station for Time series in the Ocean Canary Islands ESTOC), including measurements of pH, concentrations of total alkalinity, dissolved inorganic carbon (DIC), chlorophyll-a and dissolved inorganic nitrogen (DIN). These observational data were made available by Andres Cianca (personal communication, PLOCAN, Spain), Melchor Gonzalez and Magdalena Santana Casiano (personal communication, Universidad de Las Palmas de Gran Canaria). The choice of this location was underpinned by the fact that the first OAE mesocosm experiment was conducted on the Canary Island Gran Canaria, which will facilitate synthesizing our modelling approach with experimental findings. For our simulations at the ESTOC site in the Subtropical North Atlantic we found distinct, non-linear responses of NPP to different temporal modes of alkalinity deployment. In particular, phytoplankton bloom patterns displayed pronounced temporal phase shifts and changes in their amplitude. Notably, our simulations suggest that OAE can have a slightly stimulating effect on NPP, which is however variable, depending on the magnitude of OAE and the temporal mode of alkalinity addition. Furthermore, we find that increasing alkalinity perturbations can lead to a shift in phytoplankton community composition (towards coccolithophores), which even persists after OAE has stopped. In terms of CDR, we found that a decrease in efficiency with increasing magnitude of alkalinity addition, as well as substantial differences related to the timing of addition. Altogether, our results suggest that annual OAE during the right season (i.e. physical and biological conditions), could be a reasonable compromise in terms of logistical feasibility, efficiency of CDR and side-effects on marine biota. With respect to transferability to global models, the complex, non-linear responses of biological processes to OAE identified in our simulations do not allow for simple parameterizations that can easily adapted. Dedicated future work is required to transfer the observed responses at small spatiotemporal scales to the coarser resolution of global models.

Abstract:
This study uses an existing perturbed parameter ensemble (PPE) of simulated ocean CO2 removal (CDR) to better determine sustainable pathways of ocean-based NET deployment and to provide information to constrain the design of subsequent modelling experiments. The results show that ocean alkalinity enhancement (OAE) can only help meet SDG13 (Climate Action) when other ambitious mitigation efforts are taken. This reinforces that OAE is not a substitute for emissions reduction, but could contribute to meeting our climate goals (if other factors suggest OAE is worth doing). For SDG14 (Life Below Water), the results suggest OEA can contribute to limiting or even reversing ocean acidification. Meeting many other SDG14 objectives is closely linked to also meeting SDG13. A key recommendation is therefore, that subsequent simulations in OceanNETs should only use SDG13 compatible baseline scenarios, unless there is some specific need for process understanding at higher levels of climate change. The analysis has also determined that the idealized CDR in the PPE is not suitable for determining many socio-economic constraints and the implications that these have for meeting the SDGs. Another key recommendation is therefore, that subsequent simulations within OceanNETs should use more realistic scenarios of CDR deployment.
