High Dynamics

The northern coast of Brazil has more than 30 estuaries distributed along 650 km of coastline. These conditions favor the presence of relatively large fish communities in estuarine environments, but published information on the fish fauna in tidal creeks in northern Brazil is only available for some mangrove systems, and comparative studies between fish estuarine communities in different tidal creeks are less common. The choice of the study area was based on the fact that it has been poorly investigated with regard to estuarine fish fauna in comparison in mangrove tidal creeks using the same fishing gear. The objective of the present study was to compare the composition of the relative biomass of taxonomic, functional and ecological guilds of fish assemblages occurring in estuarine systems along the northern coast of Brazil. The study area of the present comparative analysis extended from the southeastern edge of the Marajoara Gulf to the western edge of the Maranhense Gulf. A comparative analysis among different estuarine systems was performed using data from other studies. The abundance of juveniles was greater in the Caeté, Curuçá and Cururuca estuaries than other estuaries. Cluster analysis separated the estuaries into two distinct groups and significant differences between these groups only exist in relation to geographical proximity. The present investigation indicates that the coastal region between the states of Pará and Maranhão is characterized by high dynamics and environmental heterogeneity, particularly with regard to changes in river discharge and tidal fluctuations. The present results underscore the importance of ecological information on ichthyofauna in tropical estuaries in order to include appropriate descriptors in conservation or restoration processes of marine communities and habitats.

A comparative analysis about the accumulation of heavy metal, natural and technogenic radionuclides from the Black Sea environment in different Bulgarian coastline regions is made. The possibilities to use Chlorophyta and Rhodophyta algae phylums as bioindicators in marine environment are investigated. Environmental contamination in the Black Sea alga species (green and red) was studied from 1992 to 2003. Sampling sites were selected to cover the whole coastal region. Low level gamma spectrometry was used to determine the natural and technogenic nuclide concentrations. The heavy metal concentrations were measured by Atomic Absorption Spectrometry (AAS). The obtained data show that radionuclide and metal concentrations depend on the macrophyte type. Tendencies in the concentration of pollutant variations during the studied period are examined and all data give information about different macrophytic species' ability to accumulate certain elements from one and the same sampling location. All obtained results show that use of macroalgae in marine environmental monitoring reduces the need for complex studies on chemical speciation of aquatic contaminants and makes algae valuable indicators for seawater quality assessment. All data show the lack of serious pollution along the Bulgarian Black Sea coast.
