Abstract. It is to be established, on the basis of the 
                systematic investigation of the Lower Tisza Region for ten years 
                that the water of the river has been polluted and deteriorated 
                in its quality. At present, we can only see at classifying the 
                quality of the water that for collective water supply and for 
                fish husbandry it is of second class.
                It is shown by our investigations that the solute oxygen content 
                decreases, the amount of organic matter increases in these 
                reaches. From time to time, the oxygen quantity consumed for 
                oxidizing the organic and inorganic compounds is raised by 
                passing dog n of sewage-waters. The salt content of water 
                increase of sodium content is shown by the results obtained at 
                our sampling site below the inflow of the Maros, at Tiszasziget 
                the frontier of the county. Nitrates occur in a considerable 
                quantity. The quantity of ammonia is indifferent because the 
                water supply of the population comes in this stretch not from 
                the eater of the river. By the richness in nutritive material, 
                in case of slow water flow, an algal-multiplication of large 
                mass is induced as a result of light. The increasing, 
                mineral-oil pollution also draws the attention to the protection 
                of the water quality of the river.

M. Horváth, M. and F. Kemenes, K. (1979): Water investigations of the Triple-Körös. Tiscia 14:19-23.
Abstract. We have investigated into the quality of water from samples 
                taken at Magyartés and Kunszentmárton. It could be established 
                that the water of the Triple-Körös at the sampling site in the 
                neighbourhood of Magyartés is of first class from any points of 
                view of utilization. The water samples taken at Kunszentmárton, 
                however, showed that the water quality was influenced by the 
                inflowing sewage-water. It is nonetheless obvious on the basis 
                of the seven years long investigation that the Triple-Körös is 
                our clearest river water, its pollution is of very small degree.

Hegeűs, M., Kiss, P. and Berényi, L.(1979): Salmonellae in the surface waters of Csongrád county. Tiscia 14:25-39.
                Abstract. Authors studied obligate and facultative fecal bacteria in the 
                surface waters of Csongrád county from 1976 to 1977. Samples 
                were taken monthly in general. In this paper, however, only the 
                Salmonella pollution of the Tisza and its tributaries are 
                reported. From June, 197G to December, 1977, 317 water samples 
                were enriched for the purpose of Salmonella examinations.
                During 1976, 173 Salmonella strains were isolated and found to 
                belong to 26 serotypes.
                In 1977, 295 Salmonella strains were isolated and these belonged 
                to 30 serotypes.
                The Salmonella infection of the surface waters of Csongrád 
                county as well as the spatial and time distribution of isolated 
                Salmonella serotypes are demonstrated in figures and tables.

Kiss, I. (1979): Algological investigations in the dead ars of the river Tisza at Tiszaalpár and Tiszaug. Tiscia 14:41-61.
                Abstract. 
                The present paper briefly summarizes the alga 
                flora and vegetation of two dead arms of the Tisza river on the 
                basis of investigations made between 1975-1978. In the two biotops, 258 species or intra-species taxons were found. Beyond 
                the respects of nature conservation, the investigation was 
                prompted mainly by the fact that the two bodies of standing 
                water would have different fates in the future. The smaller one 
                at Tiszaug remains a dead arm utilized as a fishery in the 
                future. The larger one at Tiszaalpár and its wider surroundings 
                will be included by a reservoir of the future TiszaIII barrage 
                where the dammed up water will be utilized for agricultural 
                irrigation and recreation purposes. Hydrobiological-algological 
                aspects of the tasks to be done before building the water 
                reservoir are also discussed.

Fintha, I. (1979): Revision of the home distribution of Wolffia arrhiza (L.). Tiscia 14:71-79.
Abstract. Our smallest 
                floriferous plant, Wolffia arrhiza (L.) HORKEL ex WIMMER 
                1857, is wide-spread in all flat areas of Europe, till the 
                latitude of 15 north, resp. till the July isothermic line of 18 
                °C (in North-western Europe: 17 °C) where there is enogh 
                eutrophic standing water, rich in nutritive matters. In 
                countries lying in the north, full of mountains or having a dry 
                climate, it is very rare or is entirely missing.
                In our country, its distribution 
                is fairly scattered although it is imaginable that, after a 
                close scrutiny, we may obtain knowledge of much more habitats. 
                It was known earlier only from the middle and south-easternn 
                parts of the territory east of the river Tisza when, in 1972, I 
                found it closed to the community Túrricse in county Szatmár. In 
                the following years, I found more and more localities of it in 
                that region and it proved to live in many places in the flatland 
                of Szatmár-Bereg and even its newer occurrences in large numbers 
                are to be expected.
                In this region, it occurs mostly 
                among Spirodela polyrrhiza, Lemna minor, Salvinia natans, 
                Utricularia vulgaris, sporadically Lemna trisulca, etc. in 
                various, convenient associations. Its ratios related to the 
                enumerated species give in the surveys, on the average, 60 to 80 
                per cent values (Its characteristics are: A-D=between 3-5, resp. 
                4-5 (5-5); K= (in every case) V). It is not rare in pure stands.
                Our knowledge of its ecology, 
                dispersion is sketchy and we are sure of that further 
                investigation of these questions will furnish several more 
                pieces of information.
                Its suggested protection also 
                means the necessity of protecting the water habitats. This is 
                equally justified by its being scientifically and economically 
                considerable.
Bodrogközy, Gy. and Horváth, I. (1979): Effect of lasting floods on the species composition and organic-matter production of the marshy meadow-lands in the floodplains of the Tisza. Tiscia 14:81-88.
Abstract. In the grasslands of floodplains enclosed between th levees of the Tisza, two associations may be separated. In the sections on higher levels Lythro (virgatae)-Alopecuretum pratensis Bodrogk. 77 is dominant and in those on lower levels Carici (melanostachyae)-Alopecuretum pratensis Soó 71, showing a transition towards the flood-plain Magnocaricion. As a result of the lasting water-covering, the meadow association, composed by species components that require hygro-mesophilic environmental essential conditions, changes into a flood-plain grass-land of helo-hygrophilous character. In the years free from lasting flood-waves, the regeneration of Lythro-Alopecuretum begins. As an intermediary stage, a meadow overgrown with weeds develops. The development of this can be hastened by the missing of regular mowings. Consequently, the seeds of Glycyrrhiza echinata, Lythrum salicaria, Iris pseudacorus, Glyceria maxima and of other species will be spread by the floods. Their fast multiplication prevents, therefore, the spread of Alopecurus pratensis.
Horváth, I. and Margóczi, K. (1979): Region reconstruction of the Tisza dead-arm at Lakitelek on the basis of the ecological investigations performed in Tőserdő. Tiscia 14:89-104.
Abstract. It can be ascertained on the 
                basis of the plant ecological investigations carried out in Tőserdő and the
                Tisza Dead-Arm at Lakitelek that these
                Tisza reaches, in spite of the anthropogenous effects, are 
                suitable for the region reconstruction. In the forests along the Dead-Tisza several autochthonous tree 
                species revive even today and the
                macrovegetation of the
                dead-arm is abundant, as well.
                Conditions of executing the region 
                    reconstruction are:
                (a) Owing to the siltation of the river bed taking place since the 
                river control, rising of the water-surface of the dead arm by 1 to 1.5 m.
                (b) Safeguarding a slow flowing through the dead-arm, in compliance 
                with the water movement, corrensponding to the meanders before the
                river-control. After creating these 
                physical conditions. the reintroduction of the plant and animal 
                species which were characteristic of the water and riverside 
                associations but exterminated because of
                anthropogenous effects.
Kozma, A. and Tölgyesi, Gy. (1979): Plant associations of flood plains along the middle Tisza and their agricultural utilization. Tiscia 14:105-122.
Abstract. The authors have 
                investigated some flood-plain areas belonging to the Middle Tisza Region and extending south of Kisköre and Abádszalók till Pusztataksony, from the points of view of their economic 
                usefulness, as well as the macro- and
                micro-element content of the plant 
                associations. The soil of the river-side and the flood-plain areas is a middling 
                acid fresh alluvial soil. The humus content and the flood-plain areas is a 
                middling acid fresh alluvial soil changes between 1 and 1.42 
                percent, the pH between 5.3 and 5.6 (measured in nKCL).
                According to the establishment of the 
                authors, the investigated areas are utilized first of all forest-economically and only 
                10-12 percent grassy area utilized with mowing, resp. paturing. With the 
                intensive Canadian poplar plantation the original 
                willow-poplar-ash plant association strongly decreases and the 
                original plant cover of the shrub and herb stratum of the forest 
                association also considerably changes. As a result of the more 
                and more frequently arising region conservation problems, it is 
                pressing and justified, to declare these areas a Region 
                Conservation District!
                In the course of investigating into the 
                macro- and micro-element content of plant species of the plant 
                association in the flood-plain areas, the authors have ascertained that the 
                mean values of the macro- and micro-element content of the plant associations the river-side and in the flood-plain exceeded in 
                every case the mean values of the meadow-hay of good quality. The authors have 
                examined the plant species 6 macro- and 7
                micro-elements in a double repetition (in 
                spring and autumn aspects).
Obradovic, M. and Budak, V. (1979): Research into flora of the southern part of the Tisa basin. Tiscia 14:123-130.
Abstract. In the 
                  present paper particular attention is devoted to the 
                  distribution, immigration and naturalization of alien species.
                  Asclepias syriaca L. has been known to be cultivated and 
                  to live in wild state in the region investigated since the begining of this 
                  century. It is naturalized, common species in !he whole region 
                  of the southern part of the Tisa Basin.
                  Echinocystis lobata (Michx.) Torr. et Gray had not been 
                  recorded for this region until 70's. Nowadays it is very 
                  common in the natural vegetation. These two North American 
                  species mentioned above escaped from the cultures.
                  Typha laxmannii Lepech. belongs to the group of the
                  adventive plant species from the East. 
                  This plant species was recorded for the first time for the 
                  southern part of Vojvodina Province around the middle of this decade. It 
                  is characterized by evident distribution, in the central parts 
                  of the Tisa Basin 
                  particularly. In the Cattail vegetation it probably forms 
                  sparse indipendent subassociation.
                  Phacelia tanacetifolia Benth. This Californian species was recorded for the 
                  southern part of the Tisa Basin (nearby Stari Becej) in 1929. It is
                  melliferous, cultivated plant which 
                  lives in wild state in ruderal vegetation. Recently we have found this 
                  beautiful adventive ephemerophyte in the surroundings of
                  Zrenjanin and Djala.
                  Nicandra physaloides (L.) Gartn., garden species from Peru, recorded for the 
                  region of Banat by Heffel in 1858. In 
                  1929 this species was found in wild state in ruderal vegetation nearby Stari BeCej. We have 
                  found this plant species on the similar habitat between Coka and
                  Ostojicevo since last year, where it is 
                  uncommon.

Abstract. Diese
                Arbeit umfasst die 
                Ergebnisse der physikalisch-chemischen 
                Untersuchungen, sowie der Zooplanktonzusammensetzung des unteren 
                Theisslaufs im Zeitraum 1975-1977. 
                Hinsichtlich der physikalisch-chemischen 
                Eigenschaften des Wassers kann als gemeinsam für alle drei 
                Untersuchungsjahre ein erhöhter Gehalt an
                suspendierten Substanzen, 
                an Phenol und Eisen 
                hervergehoben werden. Der Sauerstoffgehalt im Wasser schwankte
                um die Mittelwerte
                von 8,9-9,1 mg/1, bezw.
                77% his 84% Sáttigung.
                Die BSB5-Mittelwerte 
                betrugen von 2,0-4,6 
                mg O2/l.
                Der qualitativen Zusammensetzung nach waren 
                im Zooplankton Protozoa, 
                Rotatoria, Cladocera und Copepoda 
                verteten. Insgesamt wurden 65 
                Taxone festgestellt, davon 11 
                Protozoa, 40 Rotatoria, 
                4 Cladocera und
                10 Copepoda. 
                Die Artenanzahl varierte 
                saisonmüssig. Die 
                niedrigste Artenanzahl wurde im November
                festgestellt (7),
                die höchste im 
                August (38). Auch 
                die quantitative 
                Zooplanktonzusammensetzung wies Schwankungen auf. 
                In allen drei Jahren konnte 
                ein Maximum im Sommer 
                festgestellt werden. In den 
                übrigen Perioden unterscheiden sich 
                die Werte nicht viel, jedoch 
                sind die dominante 
                Gruppen unterschiedlich. Im Jahre 1977
                kommt auch ein zweites 
                Maximum des Zooplanktons 
                in Herbst vor, das 
                den Werten nach nicht weit 
                hinter den 
                sonnnerlichen zurückbleibt. Am 
                verschiedenartigsten, und zugleich
                am zahlreichsten waren
                die Rotatoria. 
                Die Anzahl der Arten, aber 
                auch der Einzelwesen von Cladocera 
                war sehr gering. Copepoda 
                waren etwas zahlreicher und warem mit
                verschiedenen Stadien vertreten (Nauolius und
                Copepodit).

Abstract. This paper reports on new Zooflagellate species collected in Hungary. The most important hydrochemical properties of their environment are also given. The new Mastigamoeba, Mastigella, Bicoeca, Amastigomonas and Hexamita species were recovered from various aquatic biotopes, from rivers to waste water purification plants.
Tóth, S. (1979): Preliminary investigation into the Syrphidae fauna of the Tisza-valley. Tiscia 14:163-174.
Abstract. The author has collected, among other Diptera, hover flies in the flood plain of the Tisza, since 1959. His present work is the first short summary of the Syrphidae fauna in the Tisza-valley. In the course of elaborating about 2300 specimens, he demonstrated 99 species from this area. From among these, new species are in Hungary: Triglyphus primus Loew, Neoascia geniculata Meigen, Paragus haemorrhous Meig., Pyrophaena granctitarsa Förster, Eristala abusivus Coll., and Eumerus sogdianus Stack. From among the rarer species, there are also worth mentioning: Heringia heringi Zett., Melanostoma dubium Zett, Plecocera latifrons Loew.
Tanács, L. (1979): Regeneration of the Apoidea insect fauna in the flood area, as a function of the ecological conditions. Tiscia 14:175-185.
Abstract. In flood areas, the Apoidea insect regeneration is a function of the durability resp. date of flood-waves. The vegetation regenerates one and a half, two months after the flood-waves have passed. After summer floods there cannot develop any connected plant associations more. The structure of the Apoidea insect population is determined first of all by their connection with nutritive plants. The factors determining the regeneration, resp. structure of the Apoidea population in the area investigated are the climatic conditions, the vegetation poor in species combinations, culture effects, and the distance from protecting dams.
Tanács, L. (1979): Protected areas of the flood plain of the lower-Tisza region, their Apoidea insect population and the connections of these with nutritive plants. Tiscia 14:187-196.
Abstract. The author collected I11 Apoidea species from the area investigated. In the flood plains, the richness of the Apoidea insect populations can be attributed to the connections with nitritive plants. The species combination of the vegetation depends upon the height of the level of plain, the duration and date of flood-waves.
Lövei, G. (1979): The autumn migration of the blackcap (Silvia atricapilla L.) in the Danube-bend. Tiscia 14:197-207.
Abstract. The autumn migration of the blackcap was investigated in the ringing camp of the Hungarian Ornithological Association, in Kisoroszi (47° 4i' N; 19° 03' E), in the years 1974-1976. Using wing and tail sizes, multivariate analysis was carried out and the regression of wing length, resp. wing pointedness calculated, shown by the date of passage. Relying upon these findings, the popubtíon composition of the migratory birds and the migration dynamics of populations were discussed and biometric data published. By means of regression analysis, some differences can be demonstrated in the migration behaviour of sexes.
Szitta, T. (1979): Data on the small-mammalia fauna of Tiszakarád and its environs. Tiscia 14:209-216.
Abstract. The author publishes here the results of his 
                investigations into mammals performed in the environs of Tiszakarád, September through 
                December.
                Comparing the data obtained in the course of 
                trapping here with his results in the environs of Szeged, he calls the attention to the somehow different 
                mammalian faunas of the Upper and Lower Tisza Reaches. In the Upper Tisza Region the dominance of Apodemus agrarius, in the Lower Tisza
                Region that of Apodemus sylvaticus is established.
                The author's observations of ecological 
                character, performed in the course of the investigations in 
                different biotopes, are 
                also contained in the paper.
Erdei, M. (1979): Nutrition-biological investigation into the red fox population living in thr flood plain of the Tisza-Maros. Tiscia 14:217-224.
Abstract. I am 
                summarizing my investigations performed until now in the flood-plain of the rivers Tisza and Maros in 
                connection with the nourishment-biology of the red fox, as follows:
                The relative proportion and frequency of the 
                single kinds of prey in the gastric contents is changing. It 
                depends upon the season and mainly upon the degree of inundations. In the stomachs, 
                the prey participation in mammals, birds and carcasses is the 
                largest, in respect both of total weight and relative content. 
                The other vertebrates and invertebrata as well as plants, do not form any considerable 
                proportion.
                The rodents, occurring frequently in the 
                investigated area, occur in the prey, too, more frequently. The 
                rarer ones occur in the prey, to, more rarely. But from among 
                the non-domesticated
                bird species, living in this area, only the pheasant may be 
                found in the list of preys with great frequency. The other bird 
                species, in however large number they live in the area, can be 
                met with in the list only sporadically and with low frequency. 
                This otherwise agrees with the results of the 
                nourishment-biological investigations in the southern part of 
                Hungary (Erdei, 1977).
                After analyzing the problem of advantage and 
                damage, it may be ascertained that its damaging is expressly of game-economical
                direction. 63 percent of the gastric content can be regarded as 
                originating from a harmful activity, 26 percent is useful 
                because of destroying harmful rodents, 11 percent of the gastric 
                content is indifferent. Taking into consideration that in Winter 
                the majority of the pheasant cases are cocks - sex can easily be 
                established on the basis of feather from the pectoral region -, 
                this cannot be considered as a pure damage because these are 
                mostly wounded cocks.
                Taking all things into consideration, I 
                consider the fox as a useful constituent of the biocoenosis in the 
                flood-plain. Apart from destroying harmful rodents, it also 
                performs an important hygienic role which has remained 
                exclusively its task. It replaces the role and activity of the 
                birds of prey and fur-bearing predatory animals, exterminated or becoming less 
                frequent in the meantime. So far this is possible at all under 
                the changed conditions. (Cf. Graph 2).
