Summary: Researches in pelagic community were included study of
compsition of principal sistematic groups, their vertical and horizontal
distribution in the middle Adriatic, and they mutual relations and impact
on enviromental. The data of multiannual opservations phytoplankton and
zooplankton in open middle Adriatic were published; the impact of
eutrophication on copepods in Adriatic; progressive alterations in copepode
community on eastern coastal Adriatic zone were founded; red tide was
monitored in Kaštela bay; temporal and spatial distribution of
heterotrophic bacteria in estuary of Krka river was monitored; the
influence polar radiation, temperature, salinty and pH on survival of
faecal coliforms in marine wather; temporal and spatial bacterial
distributopn was monitored under the red tide condition in Kaštela bay;
relations between bacterioplankton and phytoplanktonic species Goniaulax
polyedra was studied in condition of the red tide; multiannual temporal
series of heterotrophic bacteria density were analyzed in middle Adriatic;
impact of eutrophycation and fluctuation of environmental factors on
heterotrophic bacteria were monitored; effect of Phaeodactylum tricornutum
on the growth Flavobacterium sp. in mixed culture and under dufferent light
and temperature conditions was studied; distribution of faecal pollution
indicator under different meteorological conditions was studied in Kaštela
bay; bacterioplankton production in relation on phytoplankton production
was dwtermined in middle Adriatic; temporal productions of zooplnkton and
bacterioplnkton were studied in middle Adriatic too; the role of bacteria
and heterotrophic nanoflagellates in pelagic carbon cycle was studied in
Kaštela bay. Investigations in benthic community: composition and
distribution of benthic biocoenoses and theirs aspect in coastal and
islands zones of Adriatic was investigated; biocoenoses of National park
"Kornati" was studied; data of severals year komparative studies on
littoral bicoenoses of Kornati archipelago were performed; general reviews
of benthic flora in shorter (Split, Makarska, Dubrovnik, Bokakotorska bay,
Rogoznica cove) and biger regions (southern Adriatic) were investigated;
impact of marine pollution on phytobenthic and zoobenthic settlemnts was
studied in Spl;it, Makarska and Rogoznica regions; biological and
ecological studies of Lithophaga lithophaga was performed on many locations
in middle and southern Adriatic; new data of rarely found species
Genocidaris maculata in Adriatic was presented; ecology and biogeography of
gastropoda Prosobranchiata along eastern coast of Adriatic was studied.
Some at results and data which were obtained in the frame of the
investigations of this Project were published 30 papers. Two doctor thesis
and one master degree thesis were resulted too.
Research goals: Adriatic Sea is dynamic ecosystem with changes
happened in short and long-term time intervals. So, it is necessary to take
care on investigations on long-term fluctuations of Adriatic abiotic and
biotic components, as like on changes made by man activities. Until this
problems are not quite enough investigated (on the basis of long-term
measures of relevant parameters) we could not control Adriatic ecosistem.
The aim of this project is to take a better knowledge on coastal channels
between islands and open waters of middle Adriatic (to Italian teritorial
waters). This area, as a part of dynamic integrity of Adriatic Sea, is of a
particular significance in scientific (especially Jabuka pit and semiclosed
coastal basins), and economically view (turism, sea traffic, spawning area
of pelagic fishes). All this investigations will insure scientific basis
for forecasts of possibilities to use natural resourches of Adriatic Sea,
and plans (through the law) for more successfully protecting Adriatic Sea
from pollutions and other man activities. In times of Adriatic orientation,
it could be that all this results obtained through this project by
multidisciplinary investigations, have some basis for development in
researching sea as well as in main subjects, like economy and ecology, for
Republic Croatia. Other information about the project.
