Abstract
Cephalopods are sensitive to environmental
conditions due to their fast growth rates and short
life cycles, being thus considered good ecological
indicators. Here, we analyzed western Mediterranean
cephalopod paralarvae communities during two consecutive
summers (2004 and 2005) characterized by
contrasting oceanographic conditions. Our main aim
was to determine to what extent such contrasting
scenarios affected the spatial distribution of the
cephalopod early life stages and decipher the main
environmental factors affecting each particular taxon.
The contrasting oceanographic conditions during 2004
and 2005 included differences in the shape and
location of a regional frontal system, which brought
about differences in the sea circulation and the
temperature regime. Such contrasting scenarios were
reflected in the spatial distribution and the frequencies
of appearance of both the whole community and the
individual taxa. There was not any major factor
affecting most taxa ...
