Are e-Scooters Parked Near Bus Stops? Findings from Louisville, Kentucky
Authors: Abouelela Mohamed , Al Haddad Christelle , Antoniou Constantinos
Published: October 2021

With the increasing popularity of shared e–scooters, understanding where they are parked becomes crucial, especially for integrating them with existing public transportation services. In this study, we analyzed the relationship between trip origins and the nearest bus stops, using 506,000 shared e-scooter trips from Louisville, Kentucky. We examined this relation temporally for different hours of the day and different weekdays, but also spatially, using three metrics including land use, distance from the city center, and the Local Index of Transit Availability (LITA) accessibility index. The temporal analysis showed a different parking distance pattern during early morning hours (between 2 and 4 a.m.), whereas the spatial analysis showed no impact of spatial features on distances between scooter parking (and therefore trips starting points) and nearest bus stops.

Landscaping the Philippine Languages: The Implementation of Multilingual Education Policy
Authors: Reyes Christian Lawrence N.
Published: October 2021

The institutionalization of Mother Tongue-Based Multilingual Education (MTB-MLE) in the Philippines through the Department of Education order no. 74. series of 2009 outlining aspirations for a culture-centered mother tongue-based instruction is positioned to focus on the acquisition of language content and allow the learners to experience a theoretically based, well-planned educational program that provides a strong foundation for literacy using the cognitive skills and comprehension of academic content from day one. However, the dynamic process of teaching and learning brought many factors contributing to the implementation of the program as the key language policy of the Philippines. With this, the researcher examined the extent of program implementation through the use of qualitative and quantitative data. The study employed validated and standardized survey instruments and used Statistical Package for the Social Sciences (SPSS) to analyze the gathered data, and it applied descriptive analysis to determine the level or degree of implementation. Also, the perspectives of language teachers were taken into account to ensure a better view of the panorama as they are the end-users. Findings suggested that (1) the policy has been implemented to a great extent by the teachers; teachers have a good grasp of the program. Also, (2) teachers are providing relevant and responsive delivery of instruction in order to capitalize the learner's capability.

Objetivo: Descrever a distribuição espacial e temporal dos casos confirmados de sífilis materna no estado do Rio Grande do Norte no período de 2008 a 2018. Métodos: Trata-se de um estudo ecológico com distribuição espacial e temporal. Foram utilizados os casos confirmados de sífilis materna, com base nas informações da ficha de notificação compulsória do Sistema de Informação de Agravos de Notificação para o período de 2008 a 2018. Resultados: No período do estudo foram confirmados 2.468 casos de sífilis em gestantes, dos quais 51,4% tinham idade entre 20 e 29 anos, 60% delas se autodeclararam pardas e 24,1% possuíam escolaridade de 5a a 8a série incompleta. 42,8% obtiveram a confirmação da sífilis apenas no terceiro trimestre. Quanto à taxa de incidência, houve aumento significativo no decorrer dos anos, sendo a menor registrada no ano de 2008 (0,33) e a maior no ano de 2017 (1,22). Conclusão: A sífilis materna constitui um grave problema de saúde pública e o aumento da sua incidência evidencia falhas nos serviços. Portanto, os resultados obtidos pelo estudo poderão ser úteis no monitoramento das áreas com maior incidência, contribuindo, assim, para a implementação de estratégias eficazes na redução dos casos. Entretanto, se fazem necessários estudos de avalição dos serviços de saúde a fim de identificar fragilidades na atenção aos casos de sífilis materna.

Authors: Pessalacia Juliana Dias Reis
Published: October 2021

O avanço científico e tecnológico, atrelado ao emergente pluralismo social tem imposto desafios ao ensino de ética e bioética em cursos da área de saúde. A falta de consenso ético, pautado em modelos e teorias relativistas, desafia o debate e o exercício do julgamento moral acerca de questões de ordem prática na atuação dos profissionais. Considerando-se que a ética busca a reflexão prática com objetivo de balizar as ações humanas, torna-se necessário o estabelecimento de premissas para o entendimento do julgamento moral.

Authors: Silva Junior Osvaldo Tadeu da , Venditti Junior Rubens Venditti Junior , Santos Julio Wilson dos Santos
Published: October 2021

Introdução: Estudos mostram que o uso crônico de substâncias psicoativas está associado com redução na função cognitiva, além de afetar de forma negativa a regulação emocional reforçando o comportamento para o uso de drogas. Objetivo: analisar o efeito agudo de uma partida de futsal sobre o estado de humor e na função cognitiva em indivíduos toxicodependentes, atendidos no CAPS-ad. Métodos: Os participantes foram divididos em dois grupos, Grupo controle (n = 10) e Grupo futsal (n = 10). Para a avaliação do estado de humor foi utilizado à escala de humor de Brunel e o teste de cubos de Corsi para a memória de trabalho visuespacial. Resultados: Na análise intergrupos pós-intervenção, verificou-se redução dos fatores raiva (p = 0,008), depressão (p = 0,005) e tensão (p = 0,009). Já na análise intragrupos, o grupo futsal apresentou redução dos fatores raiva (p = 0,03), depressão (p = 0,007) e tensão (p = 0,01) evidenciando mudança no estado de humor. Em relação à memória operacional, houve um aumento na quantidade de blocos recordados (p = 0,0002) na análise intergrupos e intragrupo (p = 0,01) no grupo futsal. Conclusão: A realização de uma partida de futsal utilizada como uma estratégia não farmacológica no tratamento de dependentes químicos foi capaz de modular de forma positiva o estado de humor e a função cognitiva destes sujeitos. No entanto, o jogo de futsal ainda precisa ser mais estudado como opção de conteúdo em um programa de atividade física regular para o tratamento de dependentes químicos.

Introdução: O contexto das partidas de futebol (e.g., mando de jogo, nível competitivo, resultado da partida) pode impactar no desempenho físico dos jogadores. Objetivo: Investigar os efeitos do mando de jogo, nível competitivo e resultado final sobre o desempenho físico em jogadores profissionais. Métodos: Foram monitorados 16 jogadores da mesma equipe durante a participação em duas competições: 1ª Divisão do Campeonato Capixaba de 2020 (n = 8 partidas; n = 64 observações individuais), 1ª e 2ª Fase da Copa do Brasil de 2020 (n = 2 partidas; n = 16 observações individuais). O desempenho físico foi obtido usando o Sistema de Posicionamento Global: distância total percorrida; distância total percorrida em alta intensidade; distância total percorrida em alta aceleração. Foi utilizado o teste-t para medidas independentes. A magnitude do efeito (ES) foi calculada usando o "d" de Cohen. A regressão linear múltipla foi usada para estimar a contribuição relativa das variáveis independentes para a variação das variáveis dependentes. Resultados: Os jogos realizados “em casa” resultaram em maior demanda física em comparação aos jogos “fora de casa” (p < 0,001-0,01, ES = moderado-muito grande). Os jogos a nível nacional exigiram mais fisicamente dos jogadores em comparação aos jogos a nível estadual (p < 0,001, ES = muito grande). Partidas com vitória apresentaram maior exigência física quando comparado as partidas com derrota (p < 0,001-0,002, ES=muito grande). O local da partida e o nível competitivo têm maiores contribuições relativas para as variações na distância total (R2 = 29%) e na distância em alta aceleração (R2 = 46%). Conclusão: Os treinadores podem usar essas informações para prescrever sessões de treinamento mais representativas ao contexto de jogo.

Organic production of Green Cabbage may ensure the nutritional status and food safety for the consumers, but maintaining the productivity and economic viability of inorganic production is almost impossible for farmers of Bangladesh. At this context, a study was carried out at the Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from October 2017 to March 2018 to evaluate the efficacy of vermicompost and biochar on agronomic properties and economic of cabbage. Four biochar treatments, ( B0: 0 t ha-1 biochar, B1 :2 t ha-1 , B2 :6 t ha-1 and B3 :10 t ha-1) and three vermicompost treatments (Vc0 : 0 t ha-1, Vc1 :4 t ha-1 and Vc2 :8 t ha-1 ) were selected. B0Vc0 was considered as control. The results revealed that maximum highest plant height, number of leaves plant-1, leaf length, leaf breadth and plant spread were obtained when the B3 was mixed withVc2. But the thickness of head (10.29 cm), diameter of head (16.66 cm), % dry matter of cabbage (14.93%), weight of cabbage head plant-1 (1370 g) and yield of cabbage (52.75 t ha-1) were obtained from the treatment combination of B2Vc2. In terms of economic sustainability, the net return (Tk 523598) with highest BCR (3.70) was obtained from the treatment combination of B1Vc1.These results provide prove the effectiveness of biochar and vermicompost in sustainable Cabbage production. It also provides baseline guidelines for further investigation of choosing the appropriate combination of organic amendments based on crop requirement to maximize economic value.

Türkiye’de Enflasyon ile Ekonomik Büyüme Arasındaki Simetrik ve Asitmetrik Nedensellik İlişkilerin İncelenmesi
Authors: EMEK Ömer Fazıl , DÜŞÜNCELİ Faruk , ÖZÇELEBİ Oğuzhan
Published: October 2021

Bu çalışmanın amacı, Türkiye’de, 2005-2020 yılları arası çeyrek dönemlik veriler baz alınarak, enflasyon ve ekonomik büyüme arasındaki ilişkiyi incelemektir. Bu dönem, 2006 da örtük enflasyon rejiminden açık enflasyon rejimine geçildiği için önem arz etmektedir. Bunun için öncelikle aralarında kısa ve uzun dönem ilişkilerini belirlemek için ARDL sınır testi yaklaşımı kullanılmıştır. Daha sonra simetrik ve asimetrik nedenselliğin varlığını ve yönünü tespit etmek için Toda-Yamamoto nedensellik ve Hatemi-J asimetrik nedensellik testleri uygulanmıştır. ARDL sınır testi sonuçlarına göre enflasyon ile ekonomik büyüme arasında herhangi bir ilişki bulunmazken ekonomik büyümenin uzun dönemde enflasyonu etkilediği, ekonomik büyümede yüzde 1’lik bir artışın aynı zamanda enflasyonu da yüzde 0.09 oranında artırdığı görülmüştür. Toda-Yamamoto nedensellik sonuçlarından elde edilen ekonomik büyümeden enflasyona doğru tek yönlü nedenselliğin varlığı bu sonucu doğrulamıştır. Değişkenler arasındaki ilişkiyi pozitif ve negatif bileşenlere ayırarak bunların asimetrik etkisini dikkate alan Hatemi-J sonuçlarına göre ise her iki değişkenin birbirleri arasında pozitif yönlü nedensellik ilişkisi olduğu görülmüştür. Ayrıca pozitif enflasyondan negatif ekonomik büyümeye doğru tek yönlü bir nedenselliğin varlığı da tespit edilmiştir.
Seasonal variation of polycyclic aromatic hydrocarbon metabolites in bile of white perch Morone americana from two Chesapeake Bay tributaries
Authors: Matsche MA , Pulster EL
Published: October 2021

Polycyclic aromatic hydrocarbon (PAH) accumulation in the bile is a reliable biomarker of recent exposure to environmental PAH and elevated concentrations have been identified as significant risk factors for hepatic disease in some fish species. Recent surveys (spring 2019) revealed a high incidence of hepatic lesions in white perch Morone americana from Chesapeake Bay, but this initial survey did not detect an association between PAH metabolites and lesions. Seasonal sampling of fish was extended through the winter 2020 to increase the metabolite and hepatic lesion database and better understand annual PAH exposures to white perch. Naphthalenes, phenanthrenes, and benzo[a]pyrenes (equivalents) were analyzed in bile specimens (n = 400) using high-performance liquid chromatography with fluorescence detection. Mean concentrations of metabolites were highest in fish collected from the urbanized Severn River in summer and were lowest in fish from the more rural Choptank River in winter. Variance in metabolite concentrations were primarily due to location and season. Seasonal fluctuations in water temperature, river discharge, or feeding status had little influence on the pattern of metabolite concentrations observed. The results suggest higher exposures of fish to environmental PAH in the more developed Severn River with significant increases during summer, which could correspond to a spike in seasonal recreational motor boat use or other human activities. A better understanding of the factors that contribute to variability in PAH metabolism and the enterohepatic biliary circulation in white perch will improve the usefulness of biliary metabolites as a biomarker of PAH exposure in Chesapeake Bay and elsewhere.
Foraging areas and plasticity of yellow-eyed penguins Megadyptes antipodes in their subantarctic range
Authors: Muller CG , Chilvers BL , Chiaradia A , French RK , Kato A , Ropert-Coudert Y , Battley PF
Published: October 2021

Foraging behaviour is crucial to breeding success for marine predators, including seabirds. Yellow-eyed penguins Megadyptes antipodes are central-place, predominantly benthic foragers around mainland New Zealand. The northern (mainland) population of this Endangered species is declining, with changes in the marine environment a suspected cause, particularly warming water and poorer foraging success. We undertook a detailed foraging study of the data-deficient subantarctic population, which is distinct from the northern population. Over 2 breeding seasons, we collected 91 GPS foraging logs from 69 breeding yellow-eyed penguins from Enderby Island, Auckland Islands, New Zealand. The mean foraging distance was 24 km from shore (max 47 km). Foraging area size was greater for females and for pelagic foragers, although benthic foragers travelled further from shore on average. Diving plasticity was evident both in diving behaviour and foraging area use. Foraging area and distance from shore were greater for all birds in a year of greater breeding effort and fledging success (2016). Foraging occurred over continental shelf waters, similar to the mainland, and in areas up to 150 m deep, so any differences in foraging behaviour compared to those reported for the northern population are likely influenced by local bathymetry, environmental conditions, and individual preference. Despite comparable bathymetry in some areas, the southern population showed greater foraging plasticity, with 62% of foraging trips categorised as pelagic, implying that subantarctic foraging conditions may differ from the predominantly benthic mainland foraging. Variable foraging conditions may therefore have implications for future breeding success in the subantarctic.
Transcriptome analysis provides insights into a molecular mechanism of histamine response in the cyprid larvae of Amphibalanus amphitrite

Published: October 2021

Barnacles are notorious marine fouling creatures; their planktonic cyprid larvae attach to material substrates and metamorphose. Histamine has shown great importance in regulating cyprid settlement and metamorphosis. This study aimed to investigate the mechanisms of histamine-induced larval settlement. Cyprids were exposed to histamine or loratadine, an anti-histamine compound. The percent larval settlements of the histamine- and anti-histamine-treated cyprids were significantly higher and lower, respectively, than the control group. Transcriptomic analyses showed that histamine-treated cyprids had 18498 differentially expressed genes (DEGs, 14531 up-regulated, 3967 down-regulated) and the anti-histamine group had 18055 DEGs (17237 up-regulated, 818 down-regulated) in comparison to untreated controls. In both treatment groups, significant enrichment of DEGs involved in the mitogen-activated protein kinase signaling pathway was observed. Based on the results of larval settlement bioassays, we set 4 filter conditions to perform DEG analyses, and 19 DEGs were selected as functional genes related to cyprid settlement. The functional categories of these genes included structural proteins, spider silk proteins, energy metabolism proteins, cement proteins, glycosyl proteins, and multifunctional proteins. The energy metabolism protein AdipoR was significantly up-regulated in the histamine-treated cyprids but significantly down-regulated in the anti-histamine group. The activity of adenosine monophosphate-activated protein kinase, a downstream signaling protein of AdipoR, increased in the histamine-treated group and decreased in the anti-histamine-treated group. Our results provide new insights into the molecular mechanisms underlying the histamine-induced settlement of barnacle cyprids and identify AdipoR as an important gene that can affect the settlement of cyprids, likely through regulating cyprid energy metabolism.

The article theoretically substantiates the feasibility of implementing the concept of tax expenditures in Ukraine. It is proved that one of the problems of the economy is an unreasonable approach to the application of tax benefits, which leads to a significant budget deficit in Ukraine. The losses of EU budgets by the method of lost budget revenues are analyzed. The historical experience of realization of the concept of tax expenses is generalized. The requirements are highlighted and the main approaches to the basic structure of taxes are described. The foreign experience of determining the basic structure of taxes, the method of estimating tax expenditures and the method of accounting for tax expenditures are generalized. Based on the study of foreign experience, it is proposed to implement the concept of tax expenditures in Ukraine at the following stages: improvement of tax legislation; providing a legislative definition of the concept of "tax costs"; systematization of all expenses that will be included in tax expenses; choice of methods of collecting and analyzing information on tax expenditures; substantiation of the method of assessment and accounting of tax expenses; determining the order of reporting on tax expenditures; assessment of the effectiveness of tax expenditure management; application of evaluation results in the budget process. Signs of classification of tax expenses are singled out. It is proved that the main method of estimating tax expenditures is the method of lost budget revenues. The advantages and disadvantages of methods of accounting for tax expenditures are summarized. The models of reporting on tax expenditures are described. Groups of criteria for the effectiveness of tax expenditures are identified. The positive and negative sides of the concept of tax expenditures are substantiated.

The article analyzes the system of public finance management of the country, identifies a number of existing problems and outlines areas for further improvement and development. Emphasis is placed on the need to apply best practices in public finance management, in particular the introduction of a new instrument for coordinating fiscal and economic policy, called the European Semester, a tool for monitoring compliance with fiscal rules, similar to the German debt brake, and appropriate regulatory measures as well as the application of program-target budgeting method. It is expedient to create in Ukraine a tool similar to the European Semester in order to strengthen monitoring of the formation and implementation of fiscal, budgetary, economic policy of the state, promote broad public involvement and other stakeholders in 7collectivediscussion of budget requests, plans, concepts, socio-economic development strategies, carrying out structural economic reforms. The authors focus on the existing system of public finance management of the country, which requires an integrated approach, taking into account all components as a holistic mechanism of the system. It is emphasized that digitalization of the entire system and reduction of paperwork to zero will improve its manageability. In reforming the public financial management system, it is necessary to determine the unique role of each institution, which operates within a single mechanism and affects the effectiveness of its work, including those that assess its condition and ensure the reliability of the system, stimulate effective levers and tools finances. This will increase the efficiency of the distribution of budget expenditures, ensure the rational use of budget funds, sustainable dynamics of socio-economic development of the country, increase the welfare of citizens.

The relevance of the study of venture financing development in the era of increasing epidemiological risks is considered within the current situation in society, namely the significant impact of COVID-19 on all sectors of social and economic development. This shows the urgency of a systematic justification of current trends and peculiarities of venture financing development, taking into consideration the COVID-19 situation. The above-mentioned aspects define the purpose of our study. The theoretical basis of our study means the analysis of the specifics and priorities of venture financing, considering the timeframe from venture financing formation to nowadays. Thus, the stages of evolution of views on venture financing are highlighted. The article examines the dynamics of venture financing globally, as well as the change of relevant indicators in Europe, Asia and the United States. In particular, along with the analysis of the total amount of venture financing in each of the considered markets, the volumes of venture financing agreements that were carried out for the first time were estimated. This allowed us to analyze the relevant trends and make conclusions on the priority objects for attracting the resources of venture investors in the era of growth of epidemiological risks, depending on the experience of venture capitalists. The article compares venture funding and the incidence of COVID-19 in some countries in Europe, Asia and the United States. The approaches of European experts to the assessment of the impact of COVID-19 on venture financing are revealed. The analysis of the relevant calculations provides the possibility to structure the priorities of modern venture investors depending on the sectoral distribution of COVID-19 influences. The practical value of the study is considered within a comprehensive analysis of trends in venture financing and assessment of changes in the priorities of venture investors, considering the increasing epidemiological risks. The research may be useful both in the context of developing public venture financing policies and within developing venture financing strategies at the business level.
Another Criterion For The Riemann Hypothesis
Authors: Vega Frank
Published: October 2021

Let's define $\delta(x) = (\sum_{{q\leq x}}{\frac{1}{q}}-\log \log x-B)$, where $B \approx 0.2614972128$ is the Meissel-Mertens constant. The Robin theorem states that $\delta(x)$ changes sign infinitely often. Let's also define $S(x) = \theta(x) - x$, where $\theta(x)$ is the Chebyshev function. It is known that $S(x)$ changes sign infinitely often. We define the another function $\varpi(x) = \left(\sum_{{q\leq x}}{\frac{1}{q}}-\log \log \theta(x)-B \right)$. We prove that when the inequality $\varpi(x) \leq 0$ is satisfied for some number $x \geq 3$, then the Riemann Hypothesis should be false. The Riemann Hypothesis is also false when the inequalities $\delta(x) \leq 0$ and $S(x)\geq 0$ are satisfied for some number $x \geq 3$ or when $\frac{3 \times \log x + 5}{8 \times \pi \times \sqrt{x}} + \frac{\log x}{\log \theta(x)} \leq 1$ is satisfied for some number $x \geq 13.1$.

Objectives: Left ventricular (LV) involvement has been associated with unfavorable prognosis in arrhythmogenic cardiomyopathy (ACM). We aim to evaluate LV mechanics by cardiovascular magnetic resonance-feature tracking (CMR-FT) in ACM patients with right ventricular (RV) dysfunction.

Methods: We retrospectively recruited ACM patients diagnosed according to the revised Task Force Criteria (rTFC) from January 2015 to July 2017. All patients underwent CMR examinations and collections of clinical, electrocardiographic data. The strain and dyssynchrony parameters of LV and RV were analyzed. These patients were followed, and primary study outcome was defined as a composite of cardiovascular events (arrhythmic events and heart transplantation), secondary study outcome included arrhythmic events.

Results: Eighty-nine ACM patients (40.40 ± 13.98 years, 67.42% male) were included. LV and RV ejection fractions were 49.12 ± 12.02% and 22.28 ± 10.11%, respectively. During a median (IQR) follow-up for 18.20 (11.60-30.04) months, 30 patients experienced cardiovascular events which included 22 patients who experienced arrhythmic events. Patients with cardiovascular events had impaired LV global longitudinal strain (−10.82 ± 2.77 vs. −12.61 ± 3.18%, p = 0.010), impaired LV global circumferential strain (−11.81 ± 2.40 vs. −13.04 ± 2.83%, p = 0.044), and greater LV longitudinal dyssynchrony (LVLD) (80.98 ± 30.98 vs. 64.23 ± 25.51 ms, p = 0.012) than those without. After adjusting for age, sex, and other confounding factors, LVLD ≥89.15 ms was an independent risk factor for cardiovascular events (HR: 4.50, 95% CI: 1.94 to 10.42; p = 0.001) and for arrhythmic events (HR: 4.79, 95% CI: 1.74 to 13.20; p = 0.003).

Conclusions: LVLD by CMR-FT was an independent risk factor for cardiovascular and arrhythmic events in ACM patients in advanced stage, which could provide prognostic value for this subtype.

Since the emergence of a novel coronavirus in China at the end of December 2019, its infection - COVID-19 - has been associated with high morbidity and mortality and has left healthcare systems wrestling with the optimal management strategy, especially for vulnerable populations, such as pregnant women. At this moment, few resources exist to guide the multi-disciplinary team through decisions regarding optimal maternal-fetal treatment and delivery timing. In this article, we present the drugs and vaccines under investigation as potential treatments and prevention for COVID-19 infection. Based on a comprehensive evaluation, we prioritized these possible treatments, and provide dose-response and dose-toxicity information on each drug. Currently, there is limited but very increasing reassuring information concerning vaccines to prevent SARS-CoV-2 during pregnancy, and in this review, we also emphasize the results (mostly positive) provided by the few small trials evaluating COVID-19 vaccines in pregnant patients.

Demersal fishes constitute an essential component of the continental shelf ecosystem, and a significant element of fisheries catch around the world. However, collecting distribution and abundance data of demersal fish, necessary for their conservation and management, is usually expensive and logistically complex. The increasing availability of seafloor mapping technologies has led to the opportunity to exploit the strong relationship demersal fish exhibit with seafloor morphology to model their distribution. Multibeam echo-sounder (MBES) systems are a standard method to map seafloor morphology. The amount of acoustic energy reflected by the seafloor (backscatter) is used to estimate specific characteristics of the seafloor, including acoustic hardness and roughness. MBES data including bathymetry and depth derivatives were used to model the distribution of Abalistes stellatus, Gymnocranius grandoculis, Lagocephalus sceleratus, Lethrinus miniatus, Loxodon macrorhinus, Lutjanus sebae, and Scomberomorus queenslandicus. The possible improvement of model accuracy by adding the seafloor backscatter was tested in three different areas of the Ningaloo Marine Park off the west coast of Australia. For the majority of species, depth was a primary variable explaining their distribution in the three study sites. Backscatter was identified to be an important variable in the models, but did not necessarily lead to a significant improvement in the demersal fish distribution models’ accuracy. Possible reasons for this include: the depth and derivatives were capturing the significant changes in the habitat, or the acoustic data collected with a high-frequency MBES were not capturing accurately relevant seafloor characteristics associated with the species distribution. The improvement in the accuracy of the models for certain species using data already available is an encouraging result, which can have a direct impact in our ability to monitor these species.

Global warming is increasing ocean temperatures, forcing marine organisms to respond to a suite of changing environmental conditions. The stable oxygen isotopic composition of otoliths is often used as an index of temperature exposure, but the accuracy of the resulting temperature reconstructions in wild, free-swimming Atlantic cod (Gadus morhua) has never been groundtruthed. Based on temperatures from data storage tags (DST) and corresponding salinity values, the stable oxygen isotope (δ18O) value was predicted for each month of tagging and compared with δ18Ootolith values measured in situ with secondary ion mass spectrometry (SIMS). Paired-sample Wilcoxon tests were applied to compare measured and predicted δ18O values. The difference between measured and predicted mean and maximum δ18Ootolith values was not significant, suggesting a good correspondence between SIMS-measured and DST-predicted δ18Ootolith values. However, SIMS-measured and predicted minimum δ18Ootolith values were significantly different (all samples: p < 0.01, coastal and frontal cod: p < 0.05), resulting in overestimation of maximum temperatures. Our results confirm that otoliths are well-suited as proxies for mean ambient temperature reconstructions. A possible matrix effect and the absence of a reliable aragonite standard for SIMS measurements appeared to cause a small divergence between measured and predicted δ18Ootolith values, which affected the estimation accuracy of absolute temperature. However, relative temperature changes were accurately estimated by SIMS-analyzed δ18Ootolith values.

Many salt-marsh systems worldwide are currently threatened by drowning and lateral erosion that are not counteracted by sufficient sediment supply. Here we analyze the response of a salt-marsh system to changes in sediment availability and show that, contrary to what would have been expected, marsh dynamics in the vertical plane can be insensitive to large sediment supply. We integrate sedimentological, geochronological, paleoecological, geophysical, and chemical analyses of salt-marsh sediments accumulated over the past six centuries in the Southern Venice Lagoon (Italy), and suggest that a time lag exists between enhanced river-fed clastic sediment input and its signature in the salt-marsh succession. This time lag is likely caused by the stocking of the sediment along the margins of pre-existing marshes, which started to significantly expand horizontally – rather than accrete vertically – when sediment input increased. When sediment input drastically decreased, wind waves re-suspended the river-fed deposits and distributed them over the marsh platform, eventually allowing for vertical accretion. Understanding the response of salt-marsh systems to changes in sediment supply has important implications for the management of tidal landscapes and the prediction of their evolution under the effects of natural and anthropogenic forcings. Our results highlight that the study of ultra-recent sedimentary successions needs to be carried out on the basis of a deep understanding of specific depositional dynamics.
Freshwater Composition and Connectivity of the Connecticut River Plume During Ambient Flood Tides

Published: October 2021

The Connecticut River plume interacts with the strong tidal currents of the ambient receiving waters in eastern Long Island Sound. The plume formed during ambient flood tides is studied as an example of tidal river plumes entering into energetic ambient tidal environments in estuaries or continental shelves. Conservative passive freshwater tracers within a high-resolution nested hydrodynamic model are applied to determine how source waters from different parts of the tidal cycle contribute to plume composition and interact with bounding plume fronts. The connection to source waters can be cut off only under low-discharge conditions, when tides reverse surface flow through the mouth after max ambient flood. Upstream plume extent is limited because ambient tidal currents arrest the opposing plume propagation, as the tidal internal Froude number exceeds one. The downstream extent of the tidal plume always is within 20 km from the mouth, which is less than twice the ambient tidal excursion. Freshwaters in the river during the preceding ambient ebb are the oldest found in the new flood plume. Connectivity with source waters and plume fronts exhibits a strong upstream-to-downstream asymmetry. The arrested upstream front has high connectivity, as all freshwaters exiting the mouth immediately interact with this boundary. The downstream plume front has the lowest overall connectivity, as interaction is limited to the oldest waters since younger interior waters do not overtake this front. The offshore front and inshore boundary exhibit a downstream progression from younger to older waters and decreasing overall connectivity with source waters. Plume-averaged freshwater tracer concentrations and variances both exhibit an initial growth period followed by a longer decay period for the remainder of the tidal period. The plume-averaged tracer variance is increased by mouth inputs, decreased by entrainment, and destroyed by internal mixing. Peak entrainment velocities for younger waters are higher than values for older waters, indicating stronger entrainment closer to the mouth. Entrainment and mixing time scales (1–4 h at max ambient flood) are both shorter than half a tidal period, indicating entrainment and mixing are vigorous enough to rapidly diminish tracer variance within the plume.
