The fish genera Gasterosteus, Hucho, Oxynoemacheilus, Salmo, and Schizothorax are examples of these groups among vertebrates, and the genera Magnibursatus (Trematoda), Margaritifera, Potomida, Microcondylaea, Leguminaia, Unio (Mollusca), and Phagocata (Planaria), among invertebrates. There is reason to believe that their ancestors spread to Europe through the Paratethys (or the proto-Paratethys basin that preceded it), where intense speciation took place and new genera of aquatic organisms arose.

That way, in a narrow and large valley, away from the civilisation and its noise, you can find a mixture of colours, figures and symbols that can make you feel all sorts of different sensations. Without any established rout, the visitor himself will have to find out their own vision of the forest.

  • Basques in the Americas from 1492 To1892: a Chronology
    Basques in the Americas From 1492 to1892: A Chronology “Spanish Conquistador” by Frederic Remington Stephen T. Bass Most Recent Addendum: May 2010 FOREWORD The Basques have been a successful minority for centuries, keeping their unique culture, physiology and language alive and distinct longer than any other Western European population. In addition, outside of the Basque homeland, their efforts in the development of the New World were instrumental in helping make the U.S., Mexico, Central and South America what they are today. Most history books, however, have generally referred to these early Basque adventurers either as Spanish or French. Rarely was the term “Basque” used to identify these pioneers. Recently, interested scholars have been much more definitive in their descriptions of the origins of these Argonauts. They have identified Basque fishermen, sailors, explorers, soldiers of fortune, settlers, clergymen, frontiersmen and politicians who were involved in the discovery and development of the Americas from before Columbus’ first voyage through colonization and beyond. This also includes generations of men and women of Basque descent born in these new lands. As examples, we now know that the first map to ever show the Americas was drawn by a Basque and that the first Thanksgiving meal shared in what was to become the United States was actually done so by Basques 25 years before the Pilgrims. We also now recognize that many familiar cities and features in the New World were named by early Basques. These facts and others are shared on the following pages in a chronological review of some, but by no means all, of the involvement and accomplishments of Basques in the exploration, development and settlement of the Americas.

Consuming plate boundaries are selected on geophysical and geological grounds, and are assumed connected through modern oceanic regions by shearing and accreting boundaries. The resultant plate fragments are rotated to fit geological and morphological similarities, and the timing of tectonic events, without violating available constraints. The cumulative rotations are plotted to illustrate behind-arc spreading in the western Mediterranean basins and closure upon the Adriatic and Ionian seas from east and west following northward motion of the central Alpine plate fragment.

Concluding remarks Bibliography 1. Introduction The Bay of Biscay is an arm of the Atlantic Ocean, indenting the coast of W Europe from NW France (Offshore of Brittany) to NW Spain (Galicia). Tradition- ally the southern limit is considered to be Cape Ortegal in NW Spain, but in this contribution we follow the criterion of other authors (i.e. Sánchez and Olaso, 2004) that extends the southern limit up to Cape Finisterre, at 43∞ N latitude, in order to get a more consistent analysis of oceanographic, geomorphological and biological characteristics observed in the bay. The Bay of Biscay forms a fairly regular curve, broken on the French coast by the estuaries of the rivers (i.e. Loire and Gironde). The southeastern shore is straight and sandy whereas the Spanish coast is rugged and its northwest part is characterized by many large V-shaped coastal inlets (rias) (Evans and Prego, 2003).
