A study of the effects of salinity on the distribution and abundance of the amphipod Corophium volutator (Pallas) on the estuary of the River Ythan, Aberdeenshire, indicates that 2‰ is a critical minimum salinity controlling its distribution.
In areas with salinities between 2 and 5‰ C. volutator was present, but in reduced numbers. Breeding occurred only in salinities greater than 75‰.Cited by: Two experiments were performed to test the hypothesis that Corophium volutator affects the turbidity of water in estuaries through active resuspension of sediment.
One experiment was done in a flume system under different flow velocities, and one in. The amphipod crustacean, Corophium volutator (Pallas), is an abundant member of the intertidal infauna in the North Atlantic Ocean. Ranging from southern Norway throughout the North Sea to the Bay of Biscay and the Adriatic along the European coast and.
The upper limit of the distribution of Corophium volutator and the lower limit of the distribution of Salicornia europaea approximately correspond with mean high water of neap tide level (MHWNTL).
On the tidal flats in the Dutch Wadden Sea Corophium volutator is a dominant species of the upper intertidal zone; the closely related Corophium arenarium is usually found in the lower zone, but only in low densities (a few hundreds per m 2).
A survey in the Dutch Wadden Sea showed that this zonation pattern was only present when a muddy sediment was found in the upper zone and a sandy in the. Some effects of salinity on the distribution and abundance of Corophium volutator in the Ythan Estuary.

Draft 2, Manuscript in preparation. Corophium volutator is a species of amphipod crustacean in the family Corophiidae. It is found in mudflats of the northern Atlantic Ocean.
It is native to the north-east Atlantic Ocean, and has been introduced to the north-west Atlantic. Description. Corophium volutator is a slender animal, up to 11 millimetres ( in) long, "whitish with brown markings".

A maximum mean abundance of Corophium of about 45 ind m-2 was found on a muddy bottom and of about to 17 ind m-2 on a sand and on a silty sand bottom.

Density of adult Corophium volutator was significantly higher inside pools than outside pools, independent of mudflats (Table 2, Fig. 1a). This was observed even though mudflats accounted for a significant amount of the variation in adult density (Table 2).
The amphipod Corophium volutator has a patchy distribution which has been related to different factors (both physical and biological) at different sites. Experiments in the Wadden Sea, involving manipulation of the densities of the lugworm Arenicola marina and the bivalve Cerastoderma edule showed strong negative effects of these two species on the abundance of C.
valutator. The abundance of the latter two species was clearly not solely influenced by temperature per se but also Corophium e diversicolor was positively associated with the amphipod density, and because this omnivorous polychaete occasionally feeds on C.
volutator (Jensen and André, ; Muus, ; Ólafsson and Persson, ), the amphipods may have served as a supplementary food. The abundant amphipod Corophium volutator is an ecosystem engineer in soft-bottom intertidal communities due to its grazing and bioturbation activity.
However, the amphipod commonly serves as second intermediate host for detrimental microphallid trematodes. This host–parasite association is potentially very sensitive to climate change as the transmission rate of larval trematodes (cercariae.
Here, we studied the distribution patterns of a dominant infaunal invertebrate, the amphipod Corophium volutator, on an intertidal mudflat and evaluated the relative contribution of vital rates. An experimental study of the effects of salinity on the mud-dwelling amphipod, Corophium volutator (Pallas), indicates that, if supplied with mud, it will survive the salinity range of % 0, and without mud the range –5 % ng occurred in salinities of –46 % 0, but most frequently in the range 5–20 % occurred at a maximum rate in % 0, and only slightly.

Experiments with 2 abundant grazers, Corophium volutator and Hydrobia ulvae showed that food availability was the main driver for the spatial distribution of benthic herbivores rather than landscape morphology.

Corophium volutator lives in U-shaped burrows in the upper 5 cm of the sediment. It is known to switch between surface deposit feeding and Wlter feeding depending on the phytoplankton concentration in the water column (Riisgård and Schotge ).
However, relatively little is known about the behavioural dynamics of C. volutator throughout the. Corophium volutator.
