Abstract Seasonal and inter-annual variations in the density of the invasive polychaete Streblospio gynobranchiata were noted in the south Caspian Sea when sediment conditions were examined at five and 14 meters depths in 2005 and 2010. There was no clear trend in changing density in line one but in line two, in all seasons except summer, density of S. gynobranchiata decreased significantly. Maximum densities of 2,040 ind./m−2 and 1,013 ind./m−2 were obtained in 2005 and 2010, respectively… 

Figures and Tables from this paper

A new species of Streblospio (Polychaeta: Spionidae) from the northern Adriatic Sea (Mediterranean Sea).
TLDR
Nucleotide divergences calculated between the Adriatic specimens and the other Streblospio species are higher than the intraspecific range reported for the genus and support the description of a new species.

Population dynamics and production of Streblospio benedicti (Polychaeta) in a non-polluted estuary on the Basque coast (Gulf of Biscay)
TLDR
The population dynamics and production of a population of Streblospio benedicti from the Gernika estuary were studied monthly for one year, from May 1991 to May 1992, but the number of individuals and the annual average density were considerably lower on the Basque coast.
Changes in biodiversity of phytoplankton, zooplankton, fishes and macrobenthos in the Southern Caspian Sea after the invasion of the ctenophore Mnemiopsis Leidyi
TLDR
Monitoring for 6 years showed that the population explosion of the alien ctenophore Mnemiopsis leidyi in the southern Caspian Sea coincided with a decline in the abundance and species number of mesozooplankton, and some changes in the macrobenthic fauna were also conspicuous after the increase of this ctenophile.
Spatial distribution and biodiversity of macrofauna in the southeast of the Caspian Sea, Gorgan Bay in relation to environmental conditions
Spatial distribution and biodiversity of macrofauna in the Gorgan Bay, southeast of the Caspian Sea, were studied at fifteen stations in June 2010. Also, depth, temperature, salinity, dissolved

TLDR
D density of macrofauna increased with depths, total organic matter and percentage of silt–clay and the highest density was obtained in winter and the lowest was observed in summer, while Tubificoides fraseri was observed for the first time in the Caspian Sea.
Competition between the introduced polychaete Marenzelleria sp. and the native amphipod Monoporeia affinis in Baltic soft bottoms
TLDR
The amphipod did not increase or prolong swimming activities as a function of higher worm density, indicating that increased swimming activity over dense polychaete patches and subsequent migration away from them is not a likely explaination of why this Amphipod burrow less frequently in patches of high polychaite abundance.
Temporal changes of soft-bottom zoobenthic communities in and around Alsancak Harbor (Izmir Bay, Aegean Sea), with special attention to the autecology of exotic species.
TLDR
Collection indicate that a number of species, including those sensitive to pollution, have colonized the area where azoic conditions had been previously reported.

TLDR
Looking at changes in the bivalve community of Mission Bay in the broader context of physical change within the wetland explains some patterns of observed change and suggests effects due at least in part to Musculista, but also demonstrates the complexities associated with assessing long-term patterns in systems affected by multiple factors.
