By combining an examination of stomach contents yielding a snapshot of the most recent trophic niche and the structure of parasite communities reflecting a long‐term feeding niche, this study aimed at gaining more comprehensive information on the role of the small‐sized deep‐water velvet belly lantern shark Etmopterus spinax in the local food webs of the Galicia Bank and the canyon and valley system of the Avilés Canyon, which...

The influence of factors such as depth, near bottom temperature, near bottom salinity, fish length and diet composition on the aggregation of Scyliorhinus canicula in the Cantabrian Sea was examined. The correlation between these variables and the aggregations of each sex was low. A priori juvenile males and females were not highly discriminated by any of these environmental variables (depth, temperature and salinity) based on...

The domestication of the Eurasian grape ( Vitis vinifera ssp. sativa ) from its wild ancestor ( Vitis vinifera ssp. sylvestris ) has long been claimed to have occurred in Transcaucasia where its greatest genetic diversity is found and where very early archaeological evidence, including grape pips and artefacts of a ‘wine culture’, have been excavated. Whether from Transcaucasia or the nearby Taurus or Zagros Mountains, it is h...

Survival and recovery rates were obtained for small‐spotted catshark Scyliorhinus canicula in the Cantabrian Sea (north of Spain) based on tagging data. A total of 7656 specimens were tagged from 1993 to 2001. Recovery models for multiyear tagging studies were applied using the programme Mark. The best model fitted was achieved considering constant survival and recovery rates following the Brownie parameterization. The outputs...
