“…Recently, the Ecological Evaluation Index (EEI-c) was tested to assess the impact by using marine benthic macrophytes (macroalgae and angiosperms) in the Turkish marine waters, and the sampling was made from 56 stations which are 15 stations from the Marmara Sea [13]. In the study, revealed high ecological status class (ESC) for one site (Şarköy), good for 5 sites (Kapdağ, Edincik, Tekirdağ, Armutlu, and Marmara Ereğlisi), moderate for 2 sites (Yalova, and Kaytazdere), poor for 6 sites (Susurluk-Ağz, Bandrma, Küçükçekmece, Tuzla, Kavakldere, and Gemlik) and bad for one site (Hereke) [13]. Because of the sampling effort of the two indice (MARFEI and EEI-c) in the same time, the results of the present study are similar to EEI-c results.…”

In the present study, the Marine Floristic Ecological Index (MARFEI) was tested to assess the impacts by using marine benthic macrophytes and pressures by using the Macroalgae-Land Uses Simplified Index (MA-LUSI) in the Marmara Sea (Turkey). Sampling of benthic macrophytes was made from 0-5 m depth at 29 different sites during the summer periods of 2017, 2018 and 2019. The study revealed good ecological status class (ESC) for 6 sites, moderate for 11 sites, poor for 8 sites and bad for 4 sites. MARFEIeqr showed a negative linear relationship with the pressure index MA-LUSI.

“…species [46]. According to Taşkın et al, the Ecological Status Class (ESC) of Bostanlı (Aegean Sea, İzmir Bay) was "bad" and the highest coverage of Ecological Status Group II (opportunistic taxa) was also in this station (51.2%) [46]. Ulva spp blooms seen at various eutrophic places; Venice lagoon, North-western Mediterranean, Quequen Argentina, Brittany coast [62, 63 and 65].…”

Macro seaweeds were collected seasonally with a beam trawl from seven fixed stations in infralittoral of Gulf of Izmir to study spatiotemporal distribution of macrobenthic flora and their ecology during 2009-2010 years. A total of 6 floral species were found during the study. They were composed of an endemic marine phanerogam, Posidonia oceanica, and 5 seaweeds. The marine plants were distributed almost separately in different sectors of the gulf. Maximum average biomass was estimated for Codium bursa, followed by Ulva lactuca, Codium vermilara and dead leaves of Posidonia oceanica. Codium vermilara was found only in the inner gulf (sector), three algal seaweeds were found in the middle gulf, and Codium bursa and Posidonia oceanica in the outer gulf. A significant factor was the sector because each sector had different segmentation of the bottom depths. There was no seasonal difference even though each species contributed to the total biomass in different season. Flora assemblages were oriented with sectors of the gulf, which explained with two components. The first component was as follows: near-bottom water density followed by sea surface density was then correlated with the macrophyte biomass. Temperature of sea surface and near-bottom waters was negatively correlated with flora assemblages formed. The second component was followed by that pH of sea surface and near-bottom waters negatively correlated with the macro-seaweed communities which was positively and slightly correlated with seafloor depth and dissolved oxygen of near-bottom waters.

“…In coastal sediments, organic matter accumulation is one of the signi cant ecological processes (Kelly and Nixon 1984;Giblin et al 1997). Increased nutrient concentration as a result of anthropogenic activities such as shipping, shing, aquaculture, raw sewage disposal (Korpinen et al 2012;Micheli et al 2013;Taşkın et al 2020) lead to high primary production and organic enrichment in the sediment (Villnäs and Norkko 2011).…”

The diversity of macro and meiobenthos was documented in order to assess the ecosystem health of an anthropogenically impacted coastal ecosystem for the first time along the southwest coast of Tamil Nadu. Offshore sediment and water samples (n = 63) were collected from 14 sampling stations using the grid sampling method. Water and sediment samples were analysed for environmental variables such as pH, temperature, electrical conductivity (EC), total dissolved solids (TDS), salinity, sulphate, dissolved oxygen (DO), carbohydrate (CHO), protein, lipid, labile organic matter (LOM), total organic carbon (Corg), total organic matter (TOM) and sediment texture using standard methods. Benthic macro and meiobenthos were isolated and identified using standard identification keys. A total of 5 phyla of macrobenthos with 29 species and 5 phyla of benthos with 60 species were identified in the study area. Relative abundance analysis showed that the largest numbers of species belonged to Polychaeta for macrobenthos and foraminifera for meiobenthos. Redundancy analysis indicated that sediment carbohydrate content was the highest determining factor for explaining variation in the diversity of benthos. AMBI & M-AMBI results revealed that among the 14 stations, 2 were categorized as “poor” and 9 as “bad”. Multiple anthropogenic activities in the coastal environment leading to increased organic matter input have resulted in a decline in the ecosystem health of this region, which warrants site-specific management to control organic pollution.
