AbstractDiscrepancies in the identification of some plants and, in consequence on their autochthonous or allochthonous character, can lead to the adoption of inappropriate habit management strategies such as conservation, control, elimination, etc. A clear illustration of this is the case of a plant with an evident expansive behaviour located on the North Atlantic coast of the Iberian Peninsula, which has been considered by some authors as Spartina versicolor, a native of the European coasts. However, other authors have identified this plant as Spartina patens, originally from the North American Atlantic coasts, but introduced on both the Atlantic and Mediterranean coasts of Europe. This species shows an invading behaviour, playing a clear and evident role in the transformation of the habitats that it colonizes. In this work, results based on the use of sequences of the internal transcribed spacer (ITS) region of nrDNA, widely used in taxonomy and molecular phylogeny between closely related species, is reported. These data indicate that the identity of those plants growing on the European littoral is similar to those native to the North American Atlantic coasts.

AbstractTropical cyclone (TC) translation speed (TCTS) can affect the duration of TC-related disasters, which is critical to coastal and inland areas. The long-term variation of TCTS and their relationship to the variability of the mid-latitude jet stream and storm migration are discussed here for storms near the North Atlantic coast during 1948-2019. Our results reveal the prominent seasonality in the long-term variation of TCTS, which can be largely explained by the seasonality in the covariations of the mid-latitude jet stream and storm locations. Specifically, significant increases of TCTS occur in June and October during the past decades, which may result from the equatorward displacement of the jet stream and poleward migration of storm locations. Prominent slowdown of TCTS is found in August, which is related to the weakened jet strength and equatorward storm migration. In September, the effects of poleward displacement and weakening of the jet stream on TCTS are largely compensated by the poleward storm migration, therefore, no significant change in TCTS is observed. Meanwhile, the multidecadal variability of the Atlantic may contribute to the multidecadal variability of TCTS. Our findings emphasize the significance in taking a seasonality view in discussing the variability and trends of near-coast Atlantic TCTS under climate change.

The problem in judging M. Servan-Schreiber's message is that he reaches some sound conclusions on the basis of dubious premises, from which he derives recommendations which could be disastrous.There may be some satisfaction in seeing a Frenchman concerned with le défi, russe instead of le défi américain, but his interpretation of one is as crude as was his interpretation of the other. The shock of revelation that there are common interests of the Atlantic countries in economic as well as strategic matters is understandably more startling to a Frenchman than to others. It was all set out in 1949 in Article 2 of the North Atlantic Treaty and was restated eloquently in 1973 by Mr. Kissinger. But last spring European leaders were included to see the latter as a self-interested plea from a weak United States to a prosperous Europe. The North American countries were reminded that their role in Europe was simply to defend it on request.

During the Viking period, Norse seafarers from Greenland attempted to plant a settlement on the North American continent. This Vinland settlement faltered in its early phases and was not successful. Its failure may be best understood from the broader perspective of the Scandinavian expansion across the North Atlantic islands which began ca. AD 800. Adaptive shifts in the older North Atlantic colonies, geographical factors, and the resistance of Native Americans may have combined to doom this Western-most medieval colony.
