A large non-parasitic population of Savalia savaglia (Bertoloni, 1819) in the Boka Kotorska Bay (Montenegro)
2023
Abstract
The golden coral Savalia savaglia is a long living ecosystem engineer of the Mediterranean circalittoral assemblages, able to induce necrosis of gorgonians and black corals coenenchyme and grow on their cleaned organic skeleton. Despite its rarity, in Boka Kotorska Bay (Montenegro) a shallow population of more than 1000 colonies was recorded close to underwater freshwater springs, which create very peculiar environmental conditions. In this context, the species was extremely abundant in two sites, while gorgonians were rare. The abundance and size of S. savaglia colonies and the diversity of the entire benthic assemblage were investigated by photographic sampling in a depth range of 0–35 m. Several living fragments of S. savaglia spread on the sea floor and small settled colonies (< 5 cm height) suggested a high incidence of asexual reproduction and a non-parasitic behaviour of this population. This was confirmed by studying thin sections of the basal portion of the trunk lacking the central core due to the remains of the gorgonian host skeleton. The S. savaglia population of Boka Kotorska Bay forms the unique Mediterranean animal forest of the species. Recent important mitigation measures of anthropogenic impact are now temporary and minimal. Therefore, establishing an MPA is strongly recommended.

Validated Inventories of Non-Indigenous Species (NIS) for the Mediterranean Sea as Tools for Regional Policy and Patterns of NIS Spread
This work presents refined, updated subregional and regional non-indigenous species (NIS) inventories for the Mediterranean Sea, validated by national and taxonomic experts, with species records observed until December 2020. These datasets will be used as the baselines for the implementation of the Integrated Monitoring and Assessment Programme for the Mediterranean (IMAP) and the Mediterranean Quality Status Report 2023. In total, 1006 non-indigenous species have been found in Mediterranean marine...

First record of the endemic anthozoan Spinimuricea klavereni (Carpine &amp; Grasshoff 1975) (Cnidaria, Anthozoa, Plexauridae) in the Adriatic Sea
We present the first record of the endemic Mediterranean anthozoan Spinimuricea klavereni (Carpine &amp; Grasshoff 1975) (Cnidaria, Anthozoa, Plexauridae) for the
Adriatic Sea (Boka Kotorska bay, Montenegro). A density of 0.72 colonies m-2 could be measured in the area, which was com-pared with the
scant available data in the literature. Having in mind that this species is very rare and endemic for the Mediterranean, it is important to increase our knowledge on its distribution and biology in...

Učinci pridnenog koćarenja na bentoske zajednice u južnom Jadranu (Crna Gora)
The purpose of this study is to show the effects of bottom trawling on the benthic assemblages in the south Adriatic Sea as well as to report detailed quantitative and qualitative data on some
invertebrate groups of no commercial value that are affected by trawling. Short-term effects of bottom trawling on the soft bottom seafloor were studied on the continental shelf and upper slope in the southeastern Adriatic Sea. Ten sites were trawled in July 2011. A total of 14,069 invertebrate organisms...
