An illustrated key to the soft-bottom caprellids (Crustacea: Amphipoda) of the Iberian Peninsula and remarks to their ecological distribution along the Andalusian coast
Description
The soft-bottom caprellids of the Iberian
Peninsula are revised. Nineteen species have been reported
so far, 42 % being endemic to the Mediterranean Sea. The
lateral view of all of them is provided, together with an
illustrated key for all the species. An ecological study was
also conducted during 2007–2010 along the Andalusian
coast to explore the relationships of caprellids with abiotic
data. A total of 90 stations (0–40 m deep) were sampled
and 40 contained caprellids. Along the Atlantic, caprellids
were present in only 20 % of the stations, while along the
Mediterranean coast, caprellids were present in the 75 % of
the sampling sites. Furthermore, the abundance of caprel lids was also higher in the Mediterranean coast. The
dominant species was Pseudolirius kroyeri (present in 24
stations and showing the highest abundances with
1,780 ind/m2
), followed by Phtisica marina (22 stations)
and Pariambus typicus (11 stations). According to CCA
and BIO-ENV, sediment type, P, pH and oxygen were the
parameters that better explained the distribution of
caprellids. Although the three dominant species were found
in all types of sediment, the univariate approach showed
that P. kroyeri was significantly more abundant in fine
sediments (silt–clay and very fine sands) than in gross
sediments (coarse and very coarse sands). The majority of
studies dealing with caprellids from the Iberian Peninsula
have been focused on shallow waters and further efforts are
needed to explore biodiversity of deeper areas.
