We reconstructed the genetic structure of a planktonic crustacean Daphnia longispina living in high mountain lakes and ponds in the Pyrenees to investigate whether it was shaped by persistent founder effects originating shortly after the last glacial maximum or by ongoing dispersal and effective migration (gene flow). We found that the genetic structure can(More)
Although high mountain lakes are naturally fishless, there have been numerous trout introductions to such ecosystems in many areas of the world with negative ecological consequences. In recent decades other fishes, such as minnows, have been introduced to some mountain areas, including the Pyrenees. These introductions may cause further ecological problems,(More)
BACKGROUND The appropriate treatment of major bile duct injuries is mandatory in order to avoid serious complications, such as bile peritonitis or secondary biliary liver cirrhosis. In the last fourty years, surgical, endoscopic or radiologic techniques of cure have been proposed, but in our opinions, the preferred option is given by Roux-en-Y(More)
To evaluate the best prosthetic material in direct contact with intestinal loops in the repair of large abdominal wall defects, four cases were reevaluated and an extensive review of the literature was undertake to point out the pathophysiology of prosthetic materials in abdominal wall surgery. For its intrinsic features, Gore-Tex represents the best(More)
Edge populations are of conservation importance because of their roles as reservoirs of evolutionary potential and in understanding a given species’ ecological needs. Mainly due to loss of aquatic breeding sites, the great crested newt Triturus cristatus is amongst the fastest declining amphibian species in Europe. Focusing on the north-westerly limit of(More)
The deficiency in the distributional data of invertebrate taxa is one of the major impediments acting on the bias towards the low awareness of its conservation status. The present study sets a basic framework to understand the large branchiopods distribution in the Iberian Peninsula and Balearic Islands. Since the extensive surveys performed in the late(More)
