Response to Oxygen Deficiency (Depletion): Bivalve Assemblages As an Indicator of Ecosystem Instability in the Northern Adriatic Sea

This paper shows that Bivalve assemblages could serve as excellent indicators of disturbance and ecosystem instability. The goal of this study was to compare two sets of data in order to determine the differences between two different periods belonging to Bivalve assemblage in the muddy detritic bottom of the northern Adriatic Sea in the post-anoxic period during December 1989, 1990, 1991 and quite a while later, during 2003, 2004 and 2005. Abundances of some indicator species such as Corbula gibba, Modiolarca subpicta, and Timoclea ovata were detected during the post-anoxic period. Recruitment in the quality of Bivalve assemblages was proved by the ecologic and biotic indexes during 2003, 2004 and 2005, during a period of relatively stable ecological conditions. Fluctuation in Bivalve diversity due to the ecological quality of the marine ecosystem in the eastern part of the northern Adriatic Sea is also discussed. Key words: hypoxia; Bivalve assemblages; indicator species; soft bottoms; northern Adriatic Sea Introduction Recent reviews and summaries have provided good introductions on how hypoxia and anoxia came to be such a large and serious problem in the aquatic ecosystem (Gray et al. -

INTERTIDAL ZONATION Introduction to Oceanography Spring 2017 The
INTERTIDAL ZONATION Introduction to Oceanography Spring 2017 The Intertidal Zone is the narrow belt along the shoreline lying between the lowest and highest tide marks. The intertidal or littoral zone is subdivided broadly into four vertical zones based on the amount of time the zone is submerged. From highest to lowest, they are Supratidal or Spray Zone Upper Intertidal submergence time Middle Intertidal Littoral Zone influenced by tides Lower Intertidal Subtidal Sublittoral Zone permanently submerged The intertidal zone may also be subdivided on the basis of the vertical distribution of the species that dominate a particular zone. However, zone divisions should, in most cases, be regarded as approximate! No single system of subdivision gives perfectly consistent results everywhere. Please refer to the intertidal zonation scheme given in the attached table (last page). Zonal Distribution of organisms is controlled by PHYSICAL factors (which set the UPPER limit of each zone): 1) tidal range 2) wave exposure or the degree of sheltering from surf 3) type of substrate, e.g., sand, cobble, rock 4) relative time exposed to air (controls overheating, desiccation, and salinity changes). BIOLOGICAL factors (which set the LOWER limit of each zone): 1) predation 2) competition for space 3) adaptation to biological or physical factors of the environment Species dominance patterns change abruptly in response to physical and/or biological factors. For example, tide pools provide permanently submerged areas in higher tidal zones; overhangs provide shaded areas of lower temperature; protected crevices provide permanently moist areas. Such subhabitats within a zone can contain quite different organisms from those typical for the zone. -

Life in the Intertidal Zone
Life in the Rocky Intertidal Zone Tidepools provide a home for many animals. Tidepools are created by the changing water level, or tides. The high energy waves make this a harsh habitat, but the animals living here have adapted over time. When the earth, sun and moon align during the full and new moon we have extreme high and low tides. Generally, there are two high tides and two low tides a day. An example of low and high tide is seen on the right. There are three zones within the tidepools: the high zone, the middle zone, and the low zone. Animals are distributed based on their adaptations to different living (competition and predation) and non living (wave action and water loss) factors. The tidepools at Cabrillo are protected and have been monitored by the National Park Service since 1990. You may notice bolts in Low Tide the rocky intertidal, these are used to assist scientists in gathering data to monitor changes. Tidepool Etiquette: Human impact can hurt the animals. As you explore the tidepools, you may touch the animals living here, but only as gently as you would touch your own eyeball. Some animals may die if moved even a few inches from where they are found. Federal law prohibits collection and removal of any shells, rocks and marine specimens. Also, be aware of the changing tides, slippery rocks and unstable cliffs. Have fun exploring! High Tide High Zone The high zone is covered by the highest tides. Often this area is only sprayed by the (Supralittoral or crashing waves. -

Andrzej Falniowski* Department of Malacology, Institute of Zoology and Biomedical Research, Jagiellonian University, Poland Abstract Hydrobioids, known earlier as the family Hydrobiidae, represent a set of truncatelloidean families whose members are minute, world- wide distributed snails inhabiting mostly springs and interstitial wa- ters. More than 1,000 nominal species bear simple plesiomorphic shells, whose variability is high and overlapping between the taxa, and the soft part morphology and anatomy of the group is simplified because of miniaturization, and unified, as a result of necessary ad- aptations to the life in freshwater habitats (osmoregulation, internal fertilization and eggs rich in yolk and within the capsules). The ad- aptations arose parallel, thus represent homoplasies. All the above facts make it necessary to use molecular markers in species dis- crimination, although this should be done carefully, considering ge- netic distances calibrated at low taxonomic level.

This process aims to achieve the Good Environmental Status (GES) through the elaborated 11 Ecological Objectives and their respective common indicators. Since 2008, Contracting Parties to the Barcelona Convention have adopted the EcAp and agreed on a roadmap for its implementation. First phases of the EcAp process led to the accomplishment of 5 steps of the scheduled 7-steps process such as: 1) Definition of an Ecological Vision for the Mediterranean; 2) Setting common Mediterranean strategic goals; 3) Identification of an important ecosystem properties and assessment of ecological status and pressures; 4) Development of a set of ecological objectives corresponding to the Vision and strategic goals; and 5) Derivation of operational objectives with indicators and target levels. -
Spatiotemporal Variability in the Eelgrass Zostera Marina L. in the North-Eastern Baltic Sea: Canopy Structure and Associated Macrophyte and Invertebrate Communities

Corresponding author, [email protected] Received 3 April 2014, revised 9 May 2014, accepted 15 May 2014 Abstract. Seagrasses are marine angiosperms fulfilling important ecological functions in coastal ecosystems worldwide. Out of the 66 known seagrass species only two inhabit the Baltic Sea and only one, Zostera marina L., is found in its NE part. In the coastal waters of Estonia, where eelgrass grows at its salinity tolerance limit, only scarce information exists on the Z. marina community and there are no data on eelgrass growth. In the current study the community characteristics and growth of eelgrass were studied at four sites: Ahelaid, Saarnaki, and Sõru in the West-Estonian Archipelago Sea and Prangli in the Gulf of Finland. Fieldwork was carried out from May to September in 2005. The results showed that eelgrass grew between 1.8 and 6 m with main distribution at 2–4 m. The eelgrass bed had a considerably higher content of sediment organic matter compared to the adjacent unvegetated areas, but this difference was statistically significant only in areas where the movement of soft sediments is higher. The results also showed that altogether 19 macrophytobenthic and 23 invertebrate taxa inhabited the eelgrass stand. The prevailing vascular plants were Stuckenia pectinata and Potamogeton perfoliatus. -
