摘要 Abstract:
Community structure and faunal composition of decapod crustaceans off the
west coast of central Italy (western Mediterranean) were investigated. Samples
were collected during five trawl surveys carried out from June 1996 to June
2000 from 16 to 750 m depth. Multivariate analysis revealed the occurrence of
five faunistic assemblages: 1) a strictly coastal community over sandy bottoms
at depths <35 m; 2) a middle shelf community over sandy-muddy bottoms at
depths between 50 and 100 m; 3) a slope edge community up to 200 m depth as
a transition assemblage; 4) an upper slope community at depths between 200
and 450 m, and 5) a middle slope community at depths greater than 450 m. The
existence of a shelfslope edge transition is a characteristic of the western and
central Mediterranean where a Leptometra phalangium facies is found in many
areas at depths between 120 and 180 m. The brachyuran crab Liocarcinus
depurator dominates the shallow muddy-sandy bottoms of the shelf, while
Parapenaeus longirostris is the most abundant species from the shelf to the
upper slope assemblage. The dominant species on the middle slope are mainly
nektobenthic (Aristeus antennatus, Aristaeomorpha foliacea, Plesionika
martia), bentho-pelagic (Pasiphaea sivado) and benthic species (Nephrops
norvegicus). The average diversity of the five assemblages defined increased
with depth and the highest diversity values were found in the slope
assemblages. Depth is the main factor influencing decapod assemblage
composition, but sediment type and dissolved organic matter seem to be
secondary structuring factors particularly in the shelf zone.

摘要 Abstract:
Occurrence, distribution, and assemblage of crustaceans in the southern
Adriatic Sea were determined from data collected during five seasonal
(summer) trawl surveys carried out during 1996-2000. Trawls were conducted
at a bathymetric range of 10-800 m, by the same vessel and same sampling
gear in the framework of the E.U. Project, MEDITS. Fifty-two
benthic-epibenthic, and nektonic species (three stomatopods, 49 decapods)
were caught. Species density data (individuals per km2) were processed
according to multivariate techniques to describe the composition and
distribution of main species assemblages. The assemblages were consistent
throughout the surveyed area with some differences between the western and
eastern zones, mostly those found on shelf bottoms. The influence of
oceanographic features, other than depth, is discussed.
