description: Bivalve biomineralization is a highly complex and organized process, involving several molecular components identified in adults and larval stages. However, information is still scarce on the ontogeny of the organic matrix before calcification occurs. In this work, first shell formation was investigated in the mussel Mytilus galloprovincialis. The time course of organic matrix and CaCO3 deposition were followed at close times post fertilization (pf) (24, 26, 29, 32, 48 h) by calcofluor and calcein staining, respectively. Both components showed an exponential trend in growth, with a delay between organic matrix and CaCO3 deposition. mRNA levels of genes involved in matrix deposition (chitin synthase-CS; tyrosinase-TYR) and calcification (carbonic anhydrase-CA; extrapallial protein-EP) were quantified by qPCR at 24 and 48 hours pf (hpf) with respect to eggs. All transcripts were upregulated across early development, with TYR showing highest mRNA levels from 24 hpf. TYR transcripts were closely associated with matrix deposition as shown by in situ hybridization (ISH). The involvement of tyrosinase activity was supported by data obtained with the enzyme inhibitor N-Phenylthiourea (PTU). Our results underline the pivotal role of shell matrix in driving first CaCO3 deposition and the importance of tyrosinase in the formation of the first shell in M. galloprovincialis.

description: The connection between noncentrosymmetric materials' structure, electronic structure, and bulk photovoltaic performance remains not well understood. In particular, it is still unclear which photovoltaic (PV) mechanism(s) are relevant for the recently demonstrated visible-light ferroelectric photovoltaic (K,Ba)(Ni,Nb)O$_{3-δ}$. In this paper, we study the bulk photovoltaic effect (BPVE) of (K,Ba)(Ni,Nb)O$_{3-δ}$ and KNbO$_{3}$ by calculating the shift current from first principles. The effects of structural phase, lattice distortion, oxygen vacancies, cation arrangement, composition, and strain on BPVE are systematically studied. We find that (K,Ba)(Ni,Nb)O$_{3-δ}$ has a comparable BPVE with that of the broadly explored BiFeO$_{3}$, but for a much lower photon energy. In particular, the Glass coefficient of (K,Ba)(Ni,Nb)O$_{5}$ in a simply layered structure can be as large as 12 times that of BiFeO$_{3}$. Furthermore, the nature of the wavefunctions dictates the eventual shift current yield, which can be significantly affected and engineered by changing the O vacancy location, cation arrangement, and strain. This is not only helpful for understanding other PV mechanisms that relate to the motion of the photocurrent carriers, but also provides guidelines for the design and optimization of PV converters.

description: A new free-living marine nematode Perspiria longicaudatus sp. nov. is described from the intertidal sediments of Jinhaiwan mangrove in the South China Sea. The new species is characterized by amphideal fovea surrounded partly by body annulations; four stout cephalic setae; conical buccal cavity minute without tooth; pharynx with a peach-shaped terminal bulb; tail very long, filiform with distinct annulations; spicules strongly curved with ventral velum, cephalated proximally and tapered distally; gubernaculum with hooked caudal apophysis. The new species differs from the most similar species Perspiria striaticaudata (Timm, 1962) by unispiral amphid with thick edge, transversely loop shaped in outline; slender and strongly curved spicules with ventral velum; gubernaculum with hooked caudal apophysis and relatively longer tail. An updated key to all extant species of Perspiria is provided.

The proof uses a method due to Banks and Shparlinski. As an intermediate step, bounds for the discrete periodic autocorrelation of the finite sequence $0,\, \operatorname{e}_p(y\overline{1}), \operatorname{e}_p(y\overline{2}), \ldots, \operatorname{e}_p(y(\overline{p-1}))$ on average are obtained, where $\operatorname{e}_p(t) = \exp(2πi t/p)$ and $m\overline{m} \equiv 1\bmod p$. The latter is accomplished by adapting a method due to Kloosterman.

Diet strategies of starry smooth-hound Mustelus asterias and tope shark Galeorhinus galeus (Carcharhiniformes: Triakidae) in the Eastern English Channel: implication for conservation

description: The starry smooth-hound and the tope are subject to strong fishing pressure in the English Channel, particularly by the English and French fleets. Landings of smooth-hounds have increased sharply in France in recent years. The tope shark is mainly fished and landed by the French fleet. The present study shows contrasted food specializations by analysing the stomach contents of these two species of sharks (from the same family Triakidae). The starry smooth-hound bases its diet on Crustaceans Carcinus maenas (Linnaeus, 1758) and Liocarcinus holsatus (Fabricius, 1798) while the tope shark prefers different species of Teleosts mainly Scomber scombrus Linnaeus, 1758 and Trisopterus luscus (Linnaeus, 1758). The food specialization implies the need to maintain a good state of conservation of the prey and marine ecosystems. The functionality of habitats must be preserved to ensure their food and also their growth and reproduction. Some conservation and fisheries management measures could be proposed for the sharks (a better identification, size limit according to sexual maturity and releases live specimens at sea especially during reproduction).

description: In this paper, we show how unsupervised sense representations can be used to improve hypernymy extraction. We present a method for extracting disambiguated hypernymy relationships that propagates hypernyms to sets of synonyms (synsets), constructs embeddings for these sets, and establishes sense-aware relationships between matching synsets. Evaluation on two gold standard datasets for English and Russian shows that the method successfully recognizes hypernymy relationships that cannot be found with standard Hearst patterns and Wiktionary datasets for the respective languages.

description: Andaman and Nicobar Islands harbor diversified scleractinian corals in their continental shelf region mostly in fringing reefs. The mean live scleractinian coral cover of the Andaman Islands was 52.27% up to March 2016. The western side i.e. the Bay of Bengal coast of Andaman groups of islands had the superior live cover of corals of 60.50% in comparison with the eastern side i.e. the Andaman Sea coast. In April-May 2016, due to the impact of the El Niño event and increased sea surface temperature at 31.24 ± 0.17 (SD) which was more than 1ºC against the mean highest temperature, massive coral bleaching up to 83.6% was recorded mostly in the Andaman Sea coastal areas including a maximum of 91.5% for South Andaman region. Reef areas of North and Middle Andaman along the Bay of Bengal coastal side were not affected by bleaching due to oceanic circulation. Resilience and recovery against the bleaching were recorded with a mean of 23.69% during the post bleaching period by using the LIT method. The pre and post-bleaching surveys revealed that a total of 23.58% of the live cover were lost due to this massive bleaching.

description: Comparative effectiveness of interventional treatment strategies for the very elderly with acute coronary syndrome remains poorly defined due to study exclusions. Interventions include percutaneous coronary intervention (PCI), usually with stents, or coronary artery bypass grafting (CABG). The elderly are frequently directed to PCI because of provider perceptions that PCI is at therapeutic equipoise with CABG and that CABG incurs increased risk. We evaluated long-term outcomes of CABG versus PCI in a cohort of very elderly Medicare beneficiaries presenting with acute coronary syndrome.

description: Many dietary recommendations include reduction of excessive intake of sugar-sweetened beverages (SSBs) and other energy-rich beverages such as juices and alcohol. This study examines surveys of both individual dietary intake data and household food expenditures surveys to provide a picture of patterns and trends in beverage intake and purchases in Great Britain from 1986 to 2009, and estimates the potential for pricing policy to promote more healthful beverage purchase patterns. In 2008/09, beverages accounted for 21%, 14% and 18% of daily energy intake for children aged 1.5–18y, 4–18y, and adults (19–64y) respectively. Since the 1990s, the most important shifts are a reduction in consumption of high-fat dairy products and an increased consumption of fruit juices and reduced-fat milk among preschoolers, children and adolescents. Among adults consumption of high-fat milk beverages, sweetened tea and coffee and other energy-containing drinks fell, but reduced-fat milk, alcohol (particularly beer), and fruit juice rose. In testing taxation as an option for shifting beverage purchase patterns, we calculate that a 10% increase in the price of SSBs could potentially result in a decrease of 7.5 ml/capita/day. A similar 10% tax on high-fat milk is associated with a reduction of high-fat milk purchases by 5 ml/capita/day and increased reduced-fat milk purchase by 7 ml/capita/day. This analysis implies that taxation or other methods of shifting relative costs of these beverages could be a way to improve beverage choices in Great Britain.

description: Few trials have evaluated the metabolic effects and health outcomes of lowering dietary n-6 PUFA. The objectives of the present paper were (1) to report the methods employed to lower dietary n-6 PUFA, while either increasing or maintaining n-3 PUFA intake and (2) to validate our methods with 24 h recalls and erythrocyte fatty acid analyses. A total of sixty-seven subjects were randomised to either (1) an average-n-3 PUFA, low-n-6 PUFA (L6) intervention designed to lower linoleic acid (LA; ≤2·5 % of energy (en%)) and arachidonic acid (≤60 mg/d), while maintaining an average US intake of n-3 PUFA or (2) a high-n-3 PUFA, low-n-6 PUFA (H3-L6) intervention designed to lower n-6 LA, while increasing the n-3 PUFA α-linolenic acid (ALA; ≥1·5 en%) and EPA + DHA (≥1000 mg/d). Pre- and intra-intervention nutrient intakes were estimated with six 24 h dietary recalls per subject. Both groups achieved the targeted reductions in dietary LA to ≤2·5 en% (median LA 2·45 (2·1, 3·1); P<0·001). Intakes of n-3 PUFA did not change for the L6 group. Target increases in n-3 ALA (median 1·6 en%, (1·3, 2·0), P<0·001) and EPA + DHA (1482 mg, (374, 2558), P<0·001) were achieved in the H3-L6 group. Dietary changes were validated by corresponding changes in erythrocyte n-6 and n-3 fatty acid composition. Dietary LA can be lowered to ≤2·5 en%, with or without concurrent increases in dietary n-3 PUFA, in an outpatient clinical trial setting using this integrated diet method.

description: Wide binaries with hot subdwarf-B (sdB) primaries and main sequence companions are thought to form only through stable Roche lobe overflow (RLOF) of the sdB progenitor near the tip of the red giant branch (RGB). We present the orbital parameters of eleven new long period composite sdB binaries based on spectroscopic observations obtained with the UVES, FEROS and CHIRON spectrographs. Using all wide sdB binaries with known orbital parameters, 23 systems, the observed period distribution is found to match very well with theoretical predictions. A second result is the strong correlation between the orbital period (P) and the mass ratio (q) in the observed wide sdB binaries. In the P-q plane two distinct groups emerge, with the main group (18 systems) showing a strong correlation of lower mass ratios at longer orbital periods. The second group are systems that are thought to be formed from higher mass progenitors. Based on theoretical models, a correlation between the initial mass ratio at the start of RLOF and core mass of the sdB progenitor is found, which defines a mass-ratio range at which RLOF is stable on the RGB.

description: Let $G$ be a $2$-step stratified group of topological dimension $d$ and homogeneous dimension $Q$. Let $L$ be a homogeneous sub-Laplacian on $G$. By a theorem due to Christ and to Mauceri and Meda, an operator of the form $F(L)$ is of weak type $(1,1)$ and bounded on $L^p(G)$ for all $p \in (1,\infty)$ whenever the multiplier $F$ satisfies a scale-invariant smoothness condition of order $s > Q/2$. It is known that, for several $2$-step groups and sub-Laplacians, the threshold $Q/2$ in the smoothness condition is not sharp and in many cases it is possible to push it down to $d/2$. Here we show that, for all $2$-step groups and sub-Laplacians, the sharp threshold is strictly less than $Q/2$, but not less than $d/2$.

description: A topological insulator (TI) nanowire (NW), where the core is insulating and the 2D spin-helical Dirac fermion topological surface states (TSS) are circumferentially quantized into a series of 1D sub-bands, promises novel topological physics and applications. An axial magnetic flux (Φ) through the core drives periodic topological transitions in the surface sub-bands, changing from being all doubly-degenerate with a gapped Dirac point (DP) at integer (including zero) flux quanta (Φ$_0$ = h/e, with h being the Planck constant and e the electron charge), to contain a topologically-protected, non-degenerate 1D spin helical mode with restored DP at half-integer flux quanta. The resulting magnetoconductance is predicted to exhibit Aharonov-Bohm oscillations (ABO) with maxima occurring alternatively at half-integer or integer flux quanta (referred to as π-ABO or 0-ABO), depending periodically on the Fermi wavevector (k$_F$, with period 2π/C, C being the NW circumference). Here, we report a clear observation of such k$_F$-periodic alternations between 0-ABO and π-ABO in Bi$_2$Te$_3$ TI nanoribbon (NR, a rectangular cross sectional NW) field effect devices, which exhibit quasi-ballistic transport over ~2 μm (as manifested in length-independent conductance, exponential decaying ABO amplitude with increasing temperature (T), and an 1/T dependence of the extracted phase coherence length). The conductances as functions of the gate voltage at half and zero flux quanta also exhibit clear, but anti-correlated oscillations periodic in k$_F$ (with period 2π/C, equivalently when C encloses an integer multiples of Fermi wavelength 2π/k$_F$), consistent with the circumferentially quantized surface sub-bands. We also extract the minimal Fermi energy and momentum for TSS to emerge out of the bulk valence band, in agreement with the known Bi$_2$Te$_3$ bandstructure.
Offshore larval production of the seastar Luidia ciliaris (Asteroidea: Luidiidae) and observations on episodic recruitment inshore
Creators: name: DAN MINCHIN,
Publisher: name: Station Biologique de Roscoff (SBR)
Year: 2022

description: The asteroidea Luidia ciliaris has a long-living planktotrophic larval stage that occurs offshore on the Irish continental shelf, with few records of inshore recruitment. The larvae of two Luidia species were present in the late autumn and winter in the Celtic Sea plankton during 1989-90. The widespread occurrence of larvae in this study helps to explain the presence of juvenile and adult L. ciliaris in a south coast Irish sea-inlet, Lough Hyne, where on two occasions forty-nine years apart, strong recruitments of L. ciliaris took place. Luidia ciliaris recruited in abundance in 1982, surviving to at least a year and growing rapidly. Oceanographic movements of shelf water bearing luiidid larvae could explain these settlements inshore. While strong recruitment events of Luidia spp. seldom take place at Lough Hyne, lower levels of recruitment take place in some years most probably taking place in accordance with the annual variability of oceanographic conditions.

description: Recent studies have implicated calcium supplements with elevated vascular risk, and therefore these supplements may also relate to the occurrence of brain lesions (or hyperintensities) in older adults. These lesions represent damage to brain tissue that is caused by ischaemia. This cross sectional clinical observational study examined the association between use of calcium-containing dietary supplements and lesion volumes in a sample of 227 older adults (60 years and older). Food and supplemental calcium intakes were assessed with a Block 1998 FFQ; participants with supplemental calcium intakes above zero were categorized as supplement users. Lesion volumes were determined from cranial MRI (1.5 Tesla) using a semi-automated technique; volumes were log-transformed because they were non-normal. An ANCOVA model showed that supplement users had greater lesion volumes than non-users, even after controlling for dietary food calcium, age, sex, race, education, energy intake, depression and hypertension (Calcium supplement use: β = 0.34, SE = 0.10, F1,217 = 10.98, p = 0.0011). The influence of supplemental calcium use on lesion volume was of similar magnitude to that of hypertension, a well-established risk factor for lesions. Among supplement users, the amount of supplemental calcium was not related to lesion volume (β = −0.000035, SE = 0.00015, F1,139 = 0.06, p = 0.81). This study indicates that the use of calcium-containing dietary supplements, even low dose supplements, by older adults may be associated with greater lesion volumes. Evaluation of randomised, controlled trials is warranted to determine if this relationship is a causal one.

description: A subset of a group invariably generates the group if it generates even when we replace the elements by any of their conjugates. In a 2016 paper, Pemantle, Peres and Rivin show that the probability that four randomly selected elements invariably generate $S_n$ is bounded away from zero by an absolute constant for all $n$. Subsequently, Eberhard, Ford and Green have shown that the probability that three randomly selected elements invariably generate $S_n$ tends to zero as $n \rightarrow \infty$. In this paper, we prove an analogous result for the finite classical groups. More precisely, let $G_r(q)$ be a finite classical group of rank $r$ over $\mathbb{F}_q$. We show that for $q$ large enough, the probability that four randomly selected elements invariably generate $G_r(q)$ is bounded away from zero by an absolute constant for all $r$, and for three elements the probability tends to zero as $q \rightarrow \infty$ and $r \rightarrow \infty$. We use the fact that most elements in $G_r(q)$ are separable and the well-known correspondence between classes of maximal tori containing separable elements in classical groups and conjugacy classes in their Weyl groups.

description: Our aims were to identify the changes or stability in the structure of dietary patterns and the tracking, trends and factors related to the adherence of these patterns in China from 1991 to 2009. We used seven waves of the China Health and Nutrition Survey and included 9,253 adults with ≥3 waves complete. Diet was measured over a 3-day period with 24-hr recalls and a household food inventory. Using factor analysis in each wave we found that the structure of the two dietary patterns identified, remained stable over the studied period. The traditional southern pattern was characterized by high intake of rice, fresh leafy vegetables, low-fat red meat, pork, organ meats, poultry and fish/seafood and low intakes of wheat flour, corn/coarse grains; and the modern high-wheat pattern was characterized by high intake of wheat buns/breads, cakes/cookies/pastries, deep-fried wheat, nuts/seeds, starchy roots/tubers products, fruits, eggs/eggs products, soy milk, animal-based milk and instant noodles/frozen dumplings. Temporal tracking (maintenance of a relative position over time) was higher for the traditional southern, whereas adherence to the modern high-wheat had an upward trend over time. Higher income, education and urbanicity level were positively associated with both dietary patterns, but the association became smaller in the later years. These results suggest that even in the context of rapid economic changes in China; the way people chose to combine their foods remained relatively stable. However, the increasing popularity of the modern high-wheat pattern, a pattern associated with several energy-dense foods is cause of concern.

description: We study rational circular billiards. By viewing the trajectory formed after each reflection point to another inside the circle as the number of circle divisions into regions we derive a general formula for the number of division regions after each reflection. This will give rise to an integer division sequence. Restricting to the special cases $\vartheta =\frac{q}{2q+1}\cdot 2π$ we show that the number of regions after each reflection $n$ is beautifully related to Gauss 's arithmetic series.

description: The SEARCH Nutrition Ancillary Study aims to investigate the role of dietary intake on the development of long-term complications of type 1 diabetes in youth, and capitalise on measurement error (ME) adjustment methodology. Using the National Cancer Institute (NCI) method for episodically consumed foods, we evaluated the relationship between sugar-sweetened beverage (SSB) intake and cardiovascular risk factor profile, with the application of ME adjustment methodology. The calibration sample included 166 youth with two FFQ and three 24 h dietary recall data within 1 month. The full sample included 2286 youth with type 1 diabetes. SSB intake was significantly associated with higher TAG, total and LDL-cholesterol concentrations, after adjusting for energy, age, diabetes duration, race/ethnicity, sex and education. The estimated effect size was larger (model coefficients increased approximately 3-fold) after the application of the NCI method than without adjustment for ME. Compared with individuals consuming one serving of SSB every 2 weeks, those who consumed one serving of SSB every 2 d had 3·7 mg/dl (0·04 mmol/l) higher TAG concentrations and 4·0 mg/dl (0·10 mmol/l) higher total cholesterol and LDL-cholesterol concentrations, after adjusting for ME and covariates. SSB intake was not associated with measures of adiposity and blood pressure. Our findings suggest that SSB intake is significantly related to increased lipid levels in youth with type 1 diabetes, and that estimates of the effect size of SSB on lipid levels are severely attenuated in the presence of ME. Future studies in youth with diabetes should consider a design that will allow for the adjustment for ME when studying the influence of diet on health status.

description: We implement two-cover descent for plane quartics over Q with all 28 bitangents rational and show that on a significant collection of test cases, it resolves the existence of rational points. We also review a classical description of the relevant moduli space and use it to generate examples. We observe that local obstructions are quite rare for such curves, and only seem to occur in practice at primes of good reduction. In particular, having good reduction at 11 implies having no rational points. We also gather numerical data on two-Selmer ranks of Jacobians of these curves, which suggests that these often have non-trivial Tate-Shafarevich groups.

description: We present spectral and energy dependent timing characteristics of the hard X-ray transient IGR J17497-2821 based on XMM-Newton observations performed five and nine days after its outburst on 2006 September 17. We find that the source spectra can be well described by a hard (Gamma ~ 1.50) powerlaw and a weak multicolour disk blackbody with inner disk temperature kT_{in} ~ 0.2 KeV. A broad iron K - alpha line with FWHM ~ 27000 Km/s, consistent with that arising from an accretion disk truncated at large radius, was also detected. The power density spectra of IGR J17497 - 2821, derived from the high resolution (30 micro second) timing mode XMM-Newton observations, are characterised by broadband noise components that are well modelled by three Lorentzians. The shallow power law slope, low disk luminosity and the shape of the broadband power density spectrum indicate that the source was in the hard state. The rms variability in the softer energy bands (0.3-2 KeV) found to be ~ 1.3 times that in 2-5 and 5-10 KeV energy bands. We also present the energy dependent timing analysis of the RXTE/PCA data, where we find that at higher energies, the rms variability increases with energy.

We determine precise thresholds, assuming that the order of $G$ is large. This extends a result of Allen, Böttcher and Hladký [J. Lond. Math. Soc. (2) 84(2) (2011), 269--302] concerning the containment of squares of paths and squares of cycles of arbitrary specified lengths and settles a conjecture of theirs in the affirmative.

description: Reproduction and population dynamics studies were carried out on a population of Sabellaria alveolata from the coast of El Jadida, Morocco. For this purpose, bi-monthly samples were taken from the intertidal zone at low tide, from February 2016 to January 2017. The data obtained show that the laying of females of S. alveolata is asynchronous. It takes place from January to mid-February and from mid-March to mid-April/mid-May. At sexual maturity, they can contain up to 659000 oocytes with a maximum diameter of 79.67 µm. In year 2016, the average density varies between 9766 and 20807 ind.m-2. The average annual biomass is 1134 g m-2 (fresh weight). The population consists of 5 cohorts, with two possible juvenile recruitment periods. The first one is in early March and the second one in August. The annual production of S. alveolata is 1.713 kg m-2 year-1, with a P/B ratio of 1.51 year-1.

description: The past several years have witnessed a huge surge in the use of social media platforms during mass convergence events such as health emergencies, natural or human-induced disasters. These non-traditional data sources are becoming vital for disease forecasts and surveillance when preparing for epidemic and pandemic outbreaks. In this paper, we present GeoCoV19, a large-scale Twitter dataset containing more than 524 million multilingual tweets posted over a period of 90 days since February 1, 2020. Moreover, we employ a gazetteer-based approach to infer the geolocation of tweets. We postulate that this large-scale, multilingual, geolocated social media data can empower the research communities to evaluate how societies are collectively coping with this unprecedented global crisis as well as to develop computational methods to address challenges such as identifying fake news, understanding communities' knowledge gaps, building disease forecast and surveillance models, among others.

description: The authors report on the capture of a lot of peacock hinds, Cephalopholis argus Bloch & Schneider, 1801 from southeastern Tunisian, close to Kerkennah Islands. The specimens measured from 185 to 430 mm in total length (TL). The size of the largest specimen is a bit less than the maximum TL, 480-550 mm, generally reported for the species. Some specimens displayed differences in sizes, such patterns suggest that a population of this species is progressively establishing in the area. This record is the first for the Tunisia coast but also for the entire Mediterranean Sea. However, to avoid ciguatera fish poisoning from C. argus consumption by Tunisian peoples, this ciguatoxic species needs to be thoroughly studied in relation with diet and its captures should be carefully managed and assessed.

On fluctuations of eigenvalues of random band matrices

Publisher: name: arXiv
Year: 2015
Subjects: subject: Mathematical Physics (math-ph)

description: We consider the fluctuation of linear eigenvalue statistics of random band $n\times n$ matrices whose entries have the form $\mathcal{M}_{ij}=b^{-1/2}u^{1/2}(|i-j|)\tilde w_{ij}$ with i.i.d. $w_{ij}$ possessing the $(4+\varepsilon)$th moment, where the function $u$ has a finite support $[-C^*,C^*]$, so that $M$ has only $2C_*b+1$ nonzero diagonals. The parameter $b$ (called the bandwidth) is assumed to grow with $n$ in a way that $b/n\to 0$. Without any additional assumptions on the growth of $b$ we prove CLT for linear eigenvalue statistics for a rather wide class of test functions. Thus we improve and generalize the results of the previous papers [8] and [11], where CLT was proven under the assumption $n>>b>>n^{1/2}$. Moreover, we develop a method which allows to prove automatically the CLT for linear eigenvalue statistics of the smooth test functions for almost all classical models of random matrix theory: deformed Wigner and sample covariance matrices, sparse matrices, diluted random matrices, matrices with heavy tales, etc.

description: Sharks are generally highly exposed to overexploitation and in addition, the increased pollution in the marine environment also negatively impacts them. Therefore, it is important to monitor inorganic contaminants in sharks. This study was conducted to elucidate heavy metal accumulation in the Smooth hound Mustelus mustelus and the Blue shark Prionace glauca by electrochemical technique from the North-Eastern Mediterranean Coast of Turkey. Cadmium, chromium, cobalt, copper, iron, lead, manganese, nickel and zinc were determined. These results showed that the concentrations of all the trace metals were significantly different both in the liver and muscle tissues of Blue shark and Smooth-hound shark (P < 0.001). Cr and Pb concentrations exceeded the maximum limit legalized by FAO (2003), EU (2005), and UNEP (2008). These results confirmed that the metal contamination in the North-Eastern Mediterranean area may pose a potential threat to the sustainability of Blue shark and Smooth-hound shark in the marine ecosystem.
