    Opis:
    The Chandipore beach, situated in Balasore district, Odisha, 21°28΄N 87°01΄E / 21.47°N and 87.02°E shows an interesting nature of wave action as the water recedes up to an average of 5 kilometres during the ebb and tide, resulting in a vast, dynamic array of coastal biodiversity. It gets exposed to a huge tourism load every year and is faced with multidimensional anthropogenic interactions manifested through a varying gradient of urbanizing parameters like cattle grazing, automobile exhaust, constructions in vicinity of beach area, sewage and solid disposals etc. Present piece of work aims at documenting the premonsoon abundance and diversity of marine invertebrate fauna in this eastern Indian sea beach. Adamsia palliata, Carcinoscorpius rotundicauda, Diogenes rectimanus, Sabella sp., Astropecten mauritianas were found to be few of the prominent faunal representatives. Significant differences in respect of species richness have been observed among different selected ecozones through the coastal landscape based on tidal activity and anthropogenic exposure (F5.73, p ≤ 0.05). Such type of field-based observations leads to the scope of further estimation of the ecological status of these native organisms, their intra and inter-specific associations and functional contributions to coastal landscape playing role as a potential bioindicator, which may in turn become instrumental in frame working the future conservation scheme of these natural assets.

    Opis:
    A survey on the cyanobacterial biodiversity of 7 mangrove environments viz. Vallikunnu, Kadalundi, Kallayi, Mangalavanam, Kumbalam, Kumarakom and Mekkara mangroves of Kerala was undertaken during 2014-2016. In total, 31 species of cyanobacteria coming under 10 genera and 4 families were recorded in all mangrove environments. Maximum species (13 species) of cyanobacteria were recorded from Kadalundi, whereas the minimum was recorded from Mangalavanam (2 species). The genus Oscillatoria was observed with maximum distribution (13 species), followed by Nostoc (5 species) and Lyngbya (3 species). The genus Aphanocapsa, Microcoleus and Scytonema (2 species each) and Chroococcus, Aphanothece, Merismopedia, and Phormidium (1 species each) shows equal distribution. As many as three species, namely Oscillatoria salina, Oscillatoria ornata and Oscillatoria vizagapatensis were common in all mangrove environments except Mangalavanam and Mekkara.

    Opis:
    A biological valuation system to assess the value associated with ecosystem stability and richness (and not that from the point of view of users) is proposed to provide scientific decision support for marine protected areas and marine spatial planning. The system is based on the assessment of individual species and habitat/species assemblages. An extensive set of recently collected (2007–08) and archival (1970 –2000) data on the occurrence of marine benthos was analysed for the PolishMarine Areas. Based on matching data sets of sediments, the euphotic zone, temperature and salinity, as well as fetch and sea current values, a GIS model was used to visualise the results; a map indicates the two areas which are considered to be biologically the most valuable (Puck Bay and the stony shallows of the central coast).

    biological valuation
    Opis:
    In order to develop management strategies for sustainable use and conservation in the marine environment, reliable and meaningful, but integrated ecological information is needed. Biological valuation maps that compile and summarize all available biological and ecological information for a study area, and that allocate an overall biological value to subzones, can be used as baseline maps for future spatial planning at sea. This paper provides a concept for marine biological valuation which is based on a literature review of existing valuation criteria and the consensus reached by a discussion group of experts.

    Opis:
    Marine biological valuation provides a comprehensive concept for assessing the intrinsic value of subzones within a study area. This paper gives an update on the concept of marine biological valuation as described by Derous et al. (2007). This concept was based on a literature review of existing ecological valuation criteria and the consensus reached by a discussion group of experts during an international workshop in December 2004. The concept was discussed during an ENCORA –MARBEF workshop in December 2006, which resulted in the fine-tuning of the concept of marine biological valuation, especially with respect to its applicability to marine areas.
