F. Kemenes, K. and  M. Horváth, M.(1979): Investigation into the water quality of the Tisza from Csongrád till Tiszasziget. Tiscia 14:7-17.

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.

Pujin, V. and Stanojevic, M. (1979): Hidrobiologische Untersuchungen des unteren Theisslauf. Tiscia 14:131-138.

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).

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.

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).
