    Opis:
    Gujarat has a coast line of approximately 1700 Km, varying in different habitat conditions. The state has two gulfs viz., gulf of Khambhat and gulf of Kachchh. Edaphic conditions of different habitats in ‘Bhal’ region of Gujarat state which falls in two districts viz. Ahmedabad and Bhavnagar district of Gujarat state. The coastal vegetation depends on the edaphic conditions of the region. The coastal flora of the ‘Bhal’ region belonging to Bhavnagar district has species like Suaeda nudiflora, Prosopis chilensis, Dichanthium annulatum, etc. The ‘Bhal’ region has marshy, wetland and semi-arid habitat. The present study investigates different physico-chemical parameters like Electrical Conductivity, pH and Sodium Adsorption Ratio, as well as mineral ion Sodium, Potassium, Calcium, Magnessium and Chloride concentration in the soil of ‘Bhal’ region.

    Opis:
    The status and diversity of avifauna was studied in coastal areas of South Bengal, India from January 2014 to June 2016. The entire survey was comprehensively carried out by walking along the fixed paths/trails, for documentation of avifauna. In total, 171 bird species representing 18 orders and 54 families were recorded. Depending on movement and seasonality of occurrence, birds were classified as resident, winter migrant and local migrant. Depending on the frequency of sightings, birds were classified as: abundant, common, occasional and rare. Out of the 171 bird species, 100 were resident, 51 were winter visitor and 20 was local migrants. The maximum similarity of birds were observed between village woodland and coastal forest and lowest similarity observed between Village woodland and Sea Shore. Among the total species observed, 9.94% species were abundant, 32.75% common, 40.94% occasional and 16.37% rare. Out of the 171 species bird species recorded in the study area, three species "near threatened"; and the remaining 168 species were "least concern", according to IUCN. The present study contributed the abundance of avifauna for the first time in the coastal region of South Bengal along-with their primary habitats and migratory status.

    Vela Luka Bay
    Croatia
    Opis:
    One year qualitative and quantitative study of communities of three major taxonomic groups has been carried out at test panles placed in the upper infarlittoral zone of coastal area of Vela Luka Bay, Croatia. A list of 44 taxa was recorded. Chaetomorpha sp., Ulva sp., Fosliella farinosa, Sphacelaria cirrosa, Polysiphonia scopulorum were the most frequent dominant taxa. Among 27 algal taxa with noticeable presence only three were classified as ESG (Ecological State Groups) I. Low diversity and species richness together with massive presence of the green algae (as Ulva sp.) and negligible presence of ESG I taxa, may lead to erroneous conclusion that Vela Luka Bay is eutrophicated area. Low values of biomass and R/P (Rhodophyceae by Phaeophyceae ratio) Index together with dominance of Phaeophyta also support conclusion that there is no negative impact of nutrient enrichment on macrophyta fouling community in Vela Luka Bay.

    Opis:
    Interaction between continental and marine end-members gives rise to the natural biogeochemical processes in Sharm Al-Kharrar, a lagoon in the arid Red Sea region. Twenty-nine surface sediment samples were collected from the area and their mud fraction analysed for grain size, OC, CaCO3, mineralogy and elemental composition. The mud fraction consisted of a mixture of siliciclastic/calcareous materials, dominated by silt size materials and characterised by low OC (average 0.71% ±0.13); CaCO3 varied widely, with an average of 45% ±18. Concentrations of Al, Fe, Mn, Cu, Ni, Cr, V and Ba showed a wide range of variation throughout the Sharm. The results were normalised to Al and subjected to cluster analysis in order to examine the relations between the mineralogy and the elemental composition. The contents of Al, Fe, Mn, Cu, Ni, Cr, V and Ba appeared to be influenced by the mixing of the two end-members in addition to the physiochemical processes associated with the mixing between episodic freshwater flooding and seawater. Zn was the single element that showed a slight departure from the mixing model.

    Opis:
    The majority of the southern Baltic Sea seabed encompasses homogenous softbottom sediments of limited productivity and low biological diversity, but shallow productive areas in the coastal zone such as wetlands, vegetated lagoons and sheltered bays show a high variety of benthic habitat types offering favourable biotopic conditions for benthic fauna. Within Polish marine areas, semi-enclosed Puck Bay (the western part of the Gulf of Gdansk) ´ features an exceptionally diverse environment covering a range of benthic habitats which underscores its unique biological value and aesthetic quality and providing an impetus for conservation and ecosystem-based development. Full-coverages maps on benthic habitats in this area are therefore a necessary foundation for maritime spatial planning and implementation of strategies for sustainable management and protection of the coastal environment. This study presents the first comprehensive description and distribution of benthic habitats in Puck Bay which were categorised using the revised EUNIS 2019 classification system. Typological analyses were carried out based on inventory datasets from 1995 to 2019 including scientific publications, satellite images, open databases, topographic and geological maps, reports, theses, information available on websites and unpublished data shared willingly by individual researchers and administrative institutions. Collating various spatial data sources, that were first georeferenced and then visualized using techniques available in ArcMap 10.4.1 software (Esri), resulted in the mapping of benthic habitats and sites of important and protected plant species, which can contribute to the high confidence in environmental assessments and monitoring activities.
