Composition and structure of the parasite faunas of cod, Gadus morhua L. (Teleostei: Gadidae), in the North East Atlantic.

2008

Abstract Background Although numerous studies on parasites of the Atlantic cod, Gadus morhua L. have been conducted in the North Atlantic, comparative analyses on local cod parasite faunas are virtually lacking. The present study is based on examination of large samples of cod from six geographical areas of the North East Atlantic which yielded abundant baseline data on parasite distribution and abundance. Materials and Methods A total of 826 fish was sampled in the Baltic, Celtic, Irish and North seas, Icelandic waters and Trondheimsfjord (Norway) in 2002 (spring and autumn) and 2003 (spring). The gills and internal organs (oesophagus, stomach, intestine, pyloric caeca, liver, heart, splee…

Attitudes towards the Transatlantic Trade and Investment Partnership in the European Union: The treaty partner heuristic and issue attention

2018

Why has the Transatlantic Trade and Investment Partisanship met with strong public resistance among some Europeans and in some European Union member states, but not in others? This article argues that one important perspective to explain the pattern of support for TTIP is the role of heuristic opinion formation and issue attention. Analysing multiple waves of Eurobarometer data, I find that views of the two treaty partners, the US and the European Union, shape attitudes towards TTIP and that the largely post-materialist concerns over TTIP resonated specifically in those European countries whose citizens’ attention was less focused on economic issues. In showing how opinions towards concret…

A Global Climatology of Tropical Moisture Exports

2013

Abstract In a recent paper, a climatology of tropical moisture exports (TMEs) to the Northern Hemisphere (NH) was constructed on the basis of 7-day forward trajectories, started daily from the tropical lower troposphere, which were required to reach a water vapor flux of at least 100 g kg−1 m s−1 somewhere north of 35°N. It was shown that TMEs contribute significantly to regional precipitation. Here, the authors complement and extend this work by (i) using 6-hourly European Centre for Medium-Range Weather Forecasts (ECMWF) Interim Re-Analysis (ERA-Interim) data from 1979 to 2010 instead of the earlier 40-yr ECMWF Re-Analysis (ERA-40), (ii) extending the climatology to the Southern Hemispher…

Individual habitat transitions of Atlantic herring Clupea harengus in a human-modified coastal system

2015

Published version of an article from the journal: Marine Ecology Progress Series. Also available from Inter Research. Http://dx.doi.org/10.3354/meps11103 Pelagic marine fish often display highly dynamic migration patterns. However, such movement behaviour is usually studied at the population or school level, while less is known about individual movement characteristics and habitat transitions. During March 2012 to June 2013, we used acoustic tags and moored receivers to monitor the behaviour of Atlantic herring Clupea harengus L. (N = 47) throughout a range of habitats on the Skagerrak coast in southern Norway. Five of the tagged herring entered a former lake transformed into an artificial …

Evolution of neodymium isotopic signature of seawater during the Late Cretaceous: implications for intermediate and deep circulation.

2016

20 pages; International audience; Neodymium isotopic compositions (εNd) have been largely used for the last fifty years as a tracer of past ocean circulation, and more intensively during the last decade to investigate ocean circulation during the Cretaceous period. Despite a growing set of data, circulation patterns still remain unclear during this period. In particular, the identification of the deep-water masses and their spatial extension within the different oceanic basins are poorly constrained. In this study we present new deep-water εNd data inferred from the Nd isotope composition of fish remains and Fe–Mn oxyhydroxide coatings on foraminifera tests, along with new εNd data of resid…

Droughts Over Amazonia in 2005, 2010, and 2015: A Cloud Cover Perspective

2018

Amazon forests experienced recent severe droughts in an anomalous short period induced by different mechanisms and had different length periods and spatial patterns. Droughts of 2005 and 2010 were attributed to anomalous Sea Surface Temperature (SST) over the Tropical North Atlantic (TNA) during the dry season, but the 2010 drought was more severe and remained for a longer period because it was also induced in late 2009 by a moderate to strong El Niño (EN). Drought in 2015 led to unprecedented warming and extreme soil moisture deficits over some regions, and it was attributed to a very strong EN. Several studies analyzed these drought events regarding different climatic factors such as anom…

Amerykańscy Polacy na frontach Wielkiej Wojny: współczesny symbol i treść

2023

Założeniem niniejszego artykułu jest zebranie w sposób systematyczny dotychczasowych ustaleń badawczych związanych z dokumentowaniem działań Polaków i Amerykanów polskiego pochodzenia walczących w szeregach Amerykańskiego Korpusu Ekspedycyjnego (American Expeditionary Forces, AEF). Celem artykułu jest wskazanie przede wszystkim wymiaru historycznego, militarnego i politycznego owego zaangażowania. Artykuł stanowi studium z polityki historycznej, mające przełożenie na współczesne realia i koncepcje politycznych rozwiązań. Za narzędzia badawcze posłużyły m.in. metody: historyczna, porównawcza, statystyczna, analizy zawartości prasy, w tym szczególnie prasy polonijnej. Tematyka wymagała w spos…

Mercury in fish products: what’s the best for consumers between bluefin tuna and yellowfin tuna?

2017

A total of 205 bluefin and yellowfin tuna samples were examined for mercury detection in order to verify possible differences and have a detailed risk assessment of the two tuna species. The results showed significant higher mercury concentration in muscle tissue of bluefin tuna respect yellowfin tuna (p < 0.001) with mean concentration of 0.84 mg/kg and maximum value of 1.94 mg/kg. These differences can be due the different biological and ecological aspects of the two tuna species and to different oceanographic aspects between Atlantic Ocean and Mediterranean sea. The results obtained in this study suggest an advisable containment of the sources of pollution and further studies on the c…

A new species of the genus Zalophotrema (Digenea: Campulidae), Zalophotrema atlanticum n. sp., from the liver of the striped dolphin Stenella coerule…

1991

Zalophotrema atlanticum n. sp. from the liver of a striped dolphin, Stenella coeruleoalba (Meyen, 1833), stranded in the Canary Islands is described. This new species differs from the other Zalophotrema species in body dimensions and relative size and position of the suckers and cirrus-sac. This is the first record of a species of the genus Zalophotrema in the striped dolphin, and the Atlantic Ocean constitutes a new locality record for this genus.
