B. Aleksandrov Odessa Branch, Institute of Biology of the Southern Seas National Academy of Sciences of Ukraine
There are 142 terrestrial, 53 freshwater, and 43 marine ecoregions in the World. The Black Sea is part of the Mediterranean ecoregion. Progressive methodological approach of forming of protected areas was realized in practical nature protection conception: Pan European Ecological Network with special task on forming of marine ecological network of Europe (European Coastal Marina Ecological Network) in 1999.
Example of marine corridor of the Pan European ecological network in south-east Europe
The total protected area of the Black Sea amounts to км 2, but it differs in area in each country. The largest number of MPAs of different status is concentrated in Ukraine which has a maximum length of coastline – km or 37% and km 2 or 57% of the total Black Sea shelf area.
Review of ecological networks and corridors is one of the technical guidance manual for protected area systems Bennett G. & Mulongoy K.J. Review of experience with ecological networks, corridors and buffer zones.- Secretariat of the Convention on Biological Diversity.- Montreal, Technical Series No pp. Guiding principles for the Establishment of Marine Protected Areas in the Black Sea (approve CBD AG in 2008)
The aim of this study is to work out the methodology of a quantitative approach determining the biological value of marine aquatic areas (lagoons, bays etc.) for forming ecological corridors and determination of order of creation of new or expansions of existent МPАs (on example of marine waterbodies of Ukraine).
Peculiarities of aquatic ecosystems: 1. Concentration of life in coastal and shelf area to the depth of solar penetration. 2. Definite advantage in selection of the protected areas according to benthic biocenoses, as those bound with the landscape (in contrast to pelagic one).
Title There were singled out 34 different aquatic objects in Ukrainian part of the Black Sea coast: 13 – Bays, 13 – limans (estuaries), 2 – lagoons, 2 – lakes, 1 – Delta (Danube), 1 – Island (Zmeiny), 1 – open shelf area, 1 – strait (Kerch). K RDB – total number of Red Data Book species, K EAM – ecological activity of macrophytes, K BB – total number of benthic biocoenoses, K MZB – total number of macrozoobentic species, K P/B – ratio between plankton and benthos biomass, K PP – primary production of phytoplankton, K AI – integrated estimation of anthropogenic impact. Key characteristics of aquatic objects: К ƒ = (K i min a ) 0,5 · ( K 1 a1 · K 2 a2 · … · K n an ) 1/2n К ƒ - integrated index of biological significance of aquatic object; К 1, К 2, К n – measure of key characteristics in each aquatic object; а 1, а 2, а n – weight coefficient of each key characteristics; n – number of key characteristics.
Physical and chemical features (distribution of nutrient): Biological features (phytoplankton and zooplankton communities; macro-algae and invertebrate bottom fauna; status of species). Other features (chemicals, sediments contamination, hotspots, health issues etc.). Habitat types (structure and substrata composition of the seabed): 5 ecotones - separate analyses. K BB – total number of benthic biocoenoses, K AI – integrated estimation of anthropogenic impact K RDB – total number of Red Data Book species, K MZB – total number of macrozoobentic species, K P/B – ratio between plankton and benthos biomass, K PP – primary production of phytoplankton, K EAM – ecological activity of macrophytes. The Marine Strategy Framework Directive (Annex III, Table 1)

Values of К РР (primary productions) was determined by oxygen and radiocarbon methods, or chlorophyll « а » content were estimated in the same units (mg О 2 · l -1 · d -1 ) according to the formula: К РР = 1 - lg[8,5 / (8,5 - K average )] where K average - the value of the characteristic of a given water body. Index of ecological activity of macrophytes (К EAМ ) was determining as average of specific surface of the first three dominant species (Minicheva, 1998, Minicheva et al., 2003) on a formula: К EAМ = 10 · S/W average where - S/W average - arithmetical mean to the specific surface (S is area of surface and W is biomass of aquatic plants) of three dominant species of macrophytobenthos in each water body. Numeral value К P/B was determined for water column by above square meter of bottom surface, taking into account the middle depth of water body on a formula: К P/B = 1 - lg (1000 · K average ) / 5 where K average - the value of the characteristic of a given water body. All characteristics of biological diversity of the investigated water bodies (K MZB, K BB and K RDB were determined on formula: К i = K average / K max where K average - the value of the characteristic of a given water body, K max - the maximum possible value in a given ecotone.
