Summary: Regression equations relating body length (L) to wet
biomass (wW)have been determined for six Simulium species. In addition, for
arandomly selected mixture of different Simulium species and theirlarval
instars were analyzed. The larval material was collectedat four stations
located in the upper course of the river Kupa,which belongs to karstic NW
Dinarid area. The best fit wasobtained when potential (wW=aLb) and
quadratic function(wW=aL2-bL+c) were used.

Summary: The trophic role of rotifers in the zooplankton community
ofdimictic, oligotrophic lake Kozjak, the largest lake of PlitviceLakes, NW
Dinarid Mountains, is analyzed. Their spatial andtemporal bimass
distribution in relation to that of protozoans,cladocerans and copepods
shows that they form a significant partof the non-predatory zooplankton of
this karstic standing water.

Summary: Standing crop biomass and trophic structure of dipteran
faunawere analyzed at boulder, cobble and gravel substrata in theriver
Kupa, which belongs to the karstic running waters of theDinarid area. In
the analyzed macrobenthic communities thestanding crop biomass of dipteran
larvae constituted 1% to 75% ofthe total macroinvertebrate wet biomass per
unit area. Dipteranbiomass of headwater streams was characterized by
significantabundance of shredders. At cobble and gravel habitats in
theupper and the lower river areas the dipteran collectors comprisedthe
greatest percentage share of the total dipteran biomass.Predatory dipteran
larvae accounted on an average for 7.3% to 35%of the total predator
biomass, with the exception of gravelsubstrate in the lower river area
where the dipteran larvaeconstituted more than 60% of the total predator
biomass.

Summary: Some typical and more frequent freshwater invertebrates
ofrunning waters were studied to examine the influence of styrene,xylene
and benzene on their mortality. Snails Amphimelaniaholandri Fer. and
Lymnaea stagnalis L. and crustaceans Asselusaquaticus L. and Gammarus
fossarum Koch., were used in thesemi-static test. Compounds were added in
volume concentrationsof 0.005 to 0.4% v/v. For all concentrations LC50 was
calculatedby probit method, which demonstrated that mortality depends
muchmore on increased concentrations (depending on the
initialconcentration) than on the length of exposure. Styrene was themost
toxic, followed by xylene and then benzene. The species G.fossarum showed
marked sensitivity, followed by A. aquaticus, andthe species A. holandri
and L. stagnalis showed less sensitivity.

Summary: Contributions for review of the faunistic characteristics
of theriver Kupa were the scientific papers published in the past 30years.
Based on the literature the biocenotic components ofzoocenosis and their
distribution in different types of habitatswere analyzed in the benthal and
plankton of Lake Visovac. Thereview of macrofauna was based on the
biocenotic analyses of themost common types of benthos communities in
individual parts ofthe river's flow. The analysis of microzoobenthos was
limited tothat of the biocenotic components of macrofauna in differenttypes
of overgrowth communities. In the biocenotic aspect, withconsideration
first on the physiographic characteristics andwater chemistry of the river
Krka, according to the biocenoticstructure the macrofauna differs in 5
basic types of benthoscommunities:
- the lithoreophilic community of the source area, directly underthe Krčić
waterfall, in which the reobionts, polyoxibiontsxenosaprobic and
oligosaprobic types are dominant;
- the community of mozaic structures, in the area of the slowerflow,
composed of lithoreophilic, phytoreophilic andpsamoreophilic communities;
- the community of rapid streams in which the composition ismainly from the
lithoreophylic communities;
- the communities of travertine barriers and underwatertravertine
formations;
- the psamophilic and pelophilic communities of the bottom ofLake Visovac.
Knowledge of the macrofauna is related to the analysis ofcyanophytic and
diatomeic epilitons, as well as the periphytonthready alga, bryophytes and
macrovegetation. Analysis of thezooplankton on a few vertical profiles in
Lake Visovac shows thedependence of biocenotic and trophic characteristics
ofplanktonic communities on the thermal and chemicalstratification.

Title: Importance of dipterous larvae in the trophic structure of
benthic communities of the river Kupa
Faculty: Prirodoslovno-matematički Zagreb
Date of defense: 06/10/91
Language: hrvatski
Number of pages: 115
Summary: The dipterous fauna was investigated in different types
ofbenthic choriocenosis classified according to substrate types at12
stations located along the river Kupa from source area tomouth. The purpose
of the present study was to analyse thetemporal changes of population
density, longitudinal distributionand trophic role of dipterous fauna in
the food chains along thelongitudinal gradient of river Kupa.
Trophic structure of dipterous "Nonchironomid" fauna of the riverKupa was
characterized by the population development of predatoryrepresentatives and
by the different types of detrital consumersas the representatives of
nonpredatory dipterous fauna.
In habitats of source area the functional consumer group ofshredder was
dominant trophic category. In upper course of theriver Kupa the dipterous
larvae had the most percentage share inthe food group of collector -
filterers (79%). At theinvestigated stations located in lower course of the
river Kupanonpredatory dipterous fauna (except chironomid larvae) was
verypoorly abundant and for this reason can be taken that it does notplay
some more significant role in the trophic structure ofanalyzed
choriocenosis.
Analysis of predatory representatves of Diptera showed, thattheir biomass
was distributed uniformly and constantly along thelongitudinal profile of
the river.

Summary: The community and trophic structures of
benthicmacroinvertebrates were studied in different types of habitats inthe
karstic Plitvice Lake system located in the NW Dinaridmountains (Croatia).
The spatial distribution of functionalmacroconsumer groups shows that
longitudinal community functionalorganization does not correspond with the
RCC hypothesis.Collector guilds were the most abundant functional feeding
groupsat all the sites analyzed. The domination of shredders was foundonly
in habitats in the source areas of the supply streams. Thedistributed
longitudinal community functional organization iscaused by a discontinuum
in the gradient of physical factors,which is a result of the
geomorphological origin of travertinebarriers along the hydrosystem.

Summary: The standing crop biomass of macrobenthic predators and
itslongitudinal distribution are investigated on boulder, cobble andgravel
substrates in a karstic river located in the NW Dinaridarea (Croatia).
Dependent on substrate type and river section,the predator biomass
constituted 6.8% to 21.1% of the totalmacroinvertebrate wet biomass per
unit area. On boulder andcobble substrates more than 80% of the predator
biomassrepresented by rhyacophilid, perlodid and perlid larvae. In theupper
river section, Hirudinea species, rhyacophilid larvae anddipteran larvae
Atherix ibis constituted approximately anidentical percentage of the total
macroinvertebrates. In thelower river section Hirudinea species, Odonata
larvae, tanipodand ceratopogonid larvae are the most abundant
predators,constituting on average 90% of the total predator biomass.
The index of dominance of the predator biomass, like indices forits
concentration, is significantly greater in the habitats inthe headwater
streams and upper river section than in the lowerriver section. The Shannon
index of general diversity (H') showsthat predatory species diverity
increases from the source areadownstream.
On the basis of regression analysis, a significant positivelinear
correlation was found between species diversity ofpredators and species
diversity of collector-gatherers (r=0.96).

Summary: This study evaluated the standing crop biomass of
freshwatersnails and spatial distribution according to four substrate
types(boulders, cobbles, gravel covered with periphyton and gravelcovered
with macrophytes). The study site, in the Kupa River ofthe NW Dinarid area
of Croatia, is in a karstic region. Dependingon habitat, the gastropod wet
biomass varied from 6.4% to 43.8%of the total macroinvertebrate biomass per
unit area. Thegastropods are the dominant component of biomass on
bouldersubstrates in the upper region of the river, and on gravelsubstrates
covered with macrophytes, in the lower course. It wasfound that gastropods
are also the dominant component of thefunctional group of scrapers. The
average annual gastropodbiomass constitutes more than 80% of scrapers at
sampling sitesin the upper and lower regions of the river.

karstic river

Language: engleski
Summary: The spatial distribution of simuliid larvae and their
percentagein the standing crop biomass were investigated within
thelongitudinal functional organization of macroinvertebrates in thekarstic
river Kupa, located in the NW area of the Dinaridmountains. In general, 14
simuliid species were found, or 25.9%of all simuliid species recorded in
the balcanic region (ILLIES,1978). The majority species concentration and
biomass were foundon boulder and cobble substrate in the upper river area.
Onboulders the average annual percentage abundance was 8.5%, and oncobbles
it was 15.2% of the total macroinvertebrate biomass. Theaverage annual
percentage abundance on the same substrate type inthe headwater streams and
on gravel substrate covered withmacrophytes in the lower river area, was
less than 1%. Inconsideration of its representation in the
totalmacroinvertebrate biomass, it can be presumed that simuliidlarvae had
a significant role in functional communityorganization only in the upper
river area, where they make upfrom 70% to 80% of the total
macroinvertebrate biomass ofcollector-filterers.
