Three New Species

Ampelisca species are inhabitant of soft bottom marine benthic communities of tropical to cold – temperate zones. Prior to this paper, 11 species of the genus were recognized from Brazilian coast. Three new species of Ampelisca are herein described: Ampelisca longipropoda, Ampelisca meridionalis and Ampelisca youngi. The specimens were dredged from the continental shelf of Southwestern Atlantic Ocean between the latitudes 22°06’S and 34°32’S. A key to the Ampelisca species of the Brazilian coast is provided.

Ecological Characteristics

This paper deals with the sipunculan species distributed in Izmir Bay (Aegean Sea, eastern Mediterranean). Benthic samples were taken at 29 stations between 1998 and 2001 at depths ranging from 8 to 77 m. Six species and 200 individuals belonging to three families were found. Aspidosiphon (A.) mexicanus is newly recorded from Izmir Bay. The majority of specimens were found on a sandy-mud substratum (42%), followed by sand (35%), muddy-sand (19%) and sand (3%), respectively. Among the habitats, Posidonia oceanica and muddy-sand were represented by the highest numbers of species (4 species), followed by sandy-mud (3 species), and sand (2 species). The densities of the species at sampling stations were determined and compared seasonally, based on the data collected in 2001. Brief descriptions of the species and their distributional, reproductive and ecological characteristics are given.

Abundance And Diversity

The aim of this study is to increase the knowledge on the distribution of decapod crustaceans associated with an artificial reef positioned on sandy-mud bottoms in the central Adriatic Sea. The reef is constituted of concrete modules assembled in pyramids and concrete poles. Hard and soft bottom samples were collected from 2001, just after reef construction, to 2005 (4 surveys per year). Regarding the soft seabed, three sites close to a pyramid, three inside the reef area at a distance of 10-15 m from the structures, and three 200 m outside the reef (control sites) were randomly sampled during each survey. At the same time, three pyramids (vertical and horizontal walls) and three poles were also investigated. After taxonomical analysis, decapod crustaceans were analysed using abundance and species richness. Sites and years were compared using a balanced, fixed effect, 2-way ANOVA and PERMANOVA. In addition, SIMPER analysis was performed to identify those species typifying each community inhabiting both the soft bottom and the artificial substrates. The results showed that the artificial reef induced an increase in both abundance and diversity of the decapods of the natural habitat. In fact, man-made substrates may offer new available space for biological colonization and allow the settlement of new species usually living on hard bottoms, thus increasing the complexity of the original benthic communities.

Pagassitikos Gulf

Nutrient pollution in Pagassitikos Gulf arises mainly from the disposal of Volos untreated domestic wastewater inside Volos Bay, and also the agricultural run-off from the surrounding the Gulf cultivated areas. Volos Bay's limited circulation provides the conditions for the Bay's eutrophication by the discharge of untreated wastewater. In July 1987 this surface discharge was replaced by a new deep outfall system. The latter was located outside Volos Bay discharging primary treated effluents offshore at a depth of 55 m. To monitor any ecological changes, pre-operational (1986-1987) and operational (1988-1989) oceanographic data have been compared. The results showed a decrease in nutrient and phytoplankton concentrations between pre-operational and operational periods. Furthermore, in the vicinity of the present discharge a significant increase in the abundance of benthic communities occurred, due presumably to the continuous supply of food, adequate water circulation and high dissolved oxygen levels.
