Abstract:

Some key reproductive characters of invasive common carp, Cyprinus carpio L., were studied in an irrigation system of south-eastern Australia. Spawning occurred on a variety of natural (i.e. submerged vegetation, plant debris and stones) and artificial substrates, and the presence of 0+ individuals was an indicator of spawning success. Compared with other C. carpio stocks worldwide, the lower minimum length at maturity reflected the higher water temperatures of the region, whereas the relatively lower mean pseudo-gonadosomatic indices were attributed to less diverse food resources than those available in floodplain areas. The successful reproduction of feral C. carpio in irrigation waterways confirms its high adaptability and plasticity of traits and its classification into the phytolithophil guild, as opposed to the phytophil wild form. The findings of the present study should be given careful consideration in view of preventative measures for further spread of invasive C. carpio in similar waterways worldwide, but also for the enhancement of the species' fisheries in some man-made reservoirs.

Full text

Abstract:

This article aims to unveil the vegetal and vegetative forces underlying the creative process of Henri Matisse, arguing that phytophilia influenced every aspect of his painterly method. Drawing from the artist’s statements and broader philosophical studies of plant life, the article posits four key and closely related assertions: firstly, Matisse’s approach to his subjects required him to sink into an unconscious, vegetative state of mind, whereby the perceived entities appear to him as flows of vegetal energies rather than fixed entities. This state of mind is achieved through the cumulative act of painting and drawing, through which Matisse’s works become budding pictorial assemblages. Secondly, Matissean composition implies a vegetal organization characterized by multifocality, chromatic intensity, and spatial expansibility. Furthermore, owing to their plant-like swelling and dilation, his works have a soothing effect on the beholder and elicit his vegetative soul. Ultimately, in this article, Matisse emerges not just as a painter whose works are inhabited with vegetal shapes, but as a phytosopher whose profound knowledge of plant life permeates and informs all the constructive elements of his compositions.

Abstract:

The atmospherics of a store can affect the emotions and perceptions of consumers, and even their shopping behaviors. Despite a large body of literature on store atmospherics, only a few studies have specifically examined natural elements in this context. Following evolutionary logic, we hypothesized that introducing a potted plant to a service delivery environment would boost consumer perceptions and advance marketing objectives. Participants rated photographs of service delivery settings through an experiment on Amazon Mechanical Turk. The results showed that the stimulus (no stimulus, a plant, or a vase) affected participant ratings of the service setting. The plant was superior to both no stimulus and the vase in increasing perceived service quality and customer satisfaction. The phytophilic effect on perceptions was mediated by pleasure and moderated by exposure to greenery in daily life. The study implements evolutionary theory in store atmospherics, contributing to the theoretical foundation of the field.

Full text

Abstract:

Acariform mites of the superfamily Eriophyoidea are permanent parasites of higher vascular plants. Seasonal morphological dimorphism in females has been documented across various eriophyoid taxa, while male dimorphism remains poorly understood. In this study, we analyzed morphological, molecular, and biological data from the genus Austracus Keifer 1944, with a particular focus on the type species, A. havrylenkonis Keifer 1944, associated with Nothofagus. Using new material collected from Chile and Argentina, we demonstrated that this species exhibits two distinct forms of both males and females, making it the first known bisexually dimorphic taxon within the family Phytoptidae. The summer form of A. havrylenkonis displays the unstable annulation of the dorsal opisthosoma, characterized by a significant variation in the number of thin, microtuberculated dorsal annuli interspersed among the broader, plate-like annuli typical of the winter form. This finding aligns with the previous observations of atypical deuterogyny in Eriophyoidea and leads us to hypothesize that gall mites employ diverse adaptive strategies—manifesting as either gradual or discrete morphological changes—to cope with seasonal environmental fluctuations. Investigating the genetic mechanisms underlying these adaptive strategies, along with further studies of eriophyoids associated with Nothofagus in the Southern Hemisphere, represents a promising direction for future research.

Abstract:

The analysis results of the structural-functional organization of littoral zooplankton community of the upper Kremenchug Reservoir in the territory of Kaniv Nature Reserve during the summer of 2015 are presented. Diversity of zooplankton was presented with 34 species: Monogononta rotifers, cladocerans, copepods. The rotatoria-cladoceran zooplankton complex dominated in the taxonomic composition. Zhakkara dominant index for the comparison of the dominant species complexes was used, and it was the low number of similarities within the various biotopes of the six research stations (J = 7,1-28,6). This can be explained by the formation of higher aquatic plants.This led to the formation of specific zooplankton groups in overgrown biotopes.The ecological spectrum of the different groups of the upper Kremenchug Reservoir littoral zooplankton in the summer was characterized by the predominance of the phytophilic groups: phytophilic – 18 species (53 % of all zooplankton species). Depending on the feeding type the largest part was made by the peaceful group – 73,3 % (25 species). Summer littoral zooplankton in quantitative terms was characterized by very low development in both biotopes. Its density varied within 4077± 2098 ind./m³ and biomass 0,07 ± 0,04 g/m for overgrown biotopes, and 4123 ± 3929 ind./m³ and 0,054 ± 0,038 g/m³ for freshwater ones. Among the quantitative indicators, the species of Copepoda dominated, what was associated with the development of their larval stages (Nauplia, Сalanoida juv., Cyclopoida juv.) in the summer period.

The fish assemblage of the left Ross tributaries – the rivers Kamianka and Protoka is described. The total collected 2842 specimens. Studies were conducted in 2013 and 2020 in Kyiv and Zhytomyr regions. The current species composition includes 30 species for Kamianka and 20 species - Protoka. According to the research results, it has been established that the rivers are dominated by fish of the eurytopic ecological group, phytophils, zoobenthophages. It was found that the species composition in the studied parts of the Kamenka River is higher than in the Protoka River. This indicates the presence of a high level of biotopic diversity in comparison with other water bodies. In some areas studied there are species - from Resolution 6, adopted to create the Emerald Network. It’s such species as Rhodeus amarus (Bloch, 1782), Cobitis taenia (s.l.) Linnaeus, 1758, Misgurnus fossilis (Linnaeus, 1758). This allows us to take some reserved sites on rivers Kamianka and Protoka as objects of Emerald Network.

Abstract:

From the intestinal microbiota of Colorado potato beetles and their larvae (Leptinotarsa decemlineata), as well as from their feed – potato leaves, 18 bacteria of different species exhibiting antimicrobial activity (56% of the total number of isolated strains) were isolated. The species of bacteria from all three sources of excretion are different. The following 12 species were described for the first time in the gut microbiota of L. decemlineata larvae and imago: Micromonospora phytophila, Neobacillus drentensis, Pseudomonas gessardii, P. poae, P. rhizosphaerae, Pantoea agglomerans, Streptomyces chartreusis, S. clavifer, S. microflavus, S. rishiriensis, S. badius, and S. coelicoflavus. Antimicrobial activity was not previously known for three species (Staphylococcus argenteus, S. camponoticapitis, S. clavifer). Antimicrobial activity against methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Leuconostoc mesenteroides, multidrug-resistant P. aeruginosa, and Mycobacterium smegmatis was revealed. The gut microbiota of Colorado potato beetles can be considered an encouraging source of antibiotic–producing strains that overcome drug resistance of pathogenic bacteria, as well components of biopesticides.

Abstract:

The literature data on the life forms of Orthoptera are analyzed, and the results of own research are presented. The contribution of the representatives of different scientificschools to the study of the life forms of insects, in particular, Orthoptera, is characterized. It is emphasized that the doctrine on life forms, along with the doctrine on ecological faunal complexes, is an important area in ecology. It is noted that life forms characterize sufficiently precise the features of the living conditions of organisms due to ecological plasticity (including eury- and stenotopy), which is a reflection of their adaptive potential. The affiliation of all Orthoptera species found on the territory of Belarus to a certain life form has been established, their set has been studied. Spectrum has been compiled: it is represented by 16 groups belonging to two classes: phytophiles and geophiles (8 life forms in each). It is noted that most Orthoptera of Belarus belong to the class of phytophiles (34), which includes hortobionts: cereal (real), sedge-cereal, specialized, herbivorous and facultative; as well as tamnobionts, microtamnobiontes and specialized tamnobionts. The class of geophiles (19), but it significantly inferior in the number of constituent species. It includes open and subcover geophiles, herpetobionts, burrowing, groundmoving, eremobiontes, myrmecophiles and active fissurobionts. A rare stenobiont hygrophilous species - Chrysochraon dispar (Germ.) deserves special attention throughout its distribution area. It combines unique features that influence the ecological, phenetic and morphological structure of populations. The data obtained on the Orthoptera properties, which are manifested in the structural organization of their communities and a set of life forms specific to different habitats, allow us to consider this group of insects usable for environmental bioindicator assessment and ecological monitoring.

Abstract:

Structure of zooplankton community was studied in different biotopes of streams and beaver ponds in the Kologrivsky cluster of the State Nature Reserve “Kologrivsky Forest” named after M.G. Sinitsyn. Forty-five zooplankton species were recorded, namely, Cladocera (20), Rotifera (17), and Copepoda (8). Zooplankton was represented mostly by phytophilic ecological group (46-61% of the total number of species). Species composition of zooplankton, trophic group ratio, zooplankton abundance and biomass differed in the medium-small river, the smallest and most insignificant watercourses. In near-shore river area (ripal) and beaver ponds, overgrown by macrophytes, higher quantitative indicators of zooplankton were registered comparing to central area of the river. In addition, high zooplankton abundance and biomass were observed in permanent beaver ponds at streams.

In relation to microorganisms, a more intensive formation of biofilms and mats was revealed in the marginal areas of biotopes. Larger fouling, such as algae, also more quickly develop the marginal areas of a discrete landscape and serve as a secondary biotope already for phytophilic invertebrates, which are characterized in these artificial biotopes by several times and sometimes by an order of magnitude greater abundance and biomass compared to adjacent standard conditions. The marginal ecotone aggregations also revealed increased polyp size and elevated concentrations of catalase in some molluscs and invertebrate larvae.

Abstract:

The Currais Islands is a group of a few small rocky islands in the state of Paraná, in southern Brazil, which provides an interesting location for the study of ascidians. Subtidal diversity is very high and the islands have recently been proposed as a Conservation Unit. A field study was established on the largest island to understand ascidian distributions on spatial and temporal scales. Transects, sampled three times during 2002 and 2003, were established on northern and southern locations of the island as well as at three depths. Twenty species were recorded; the most common were Didemnum rodriguesi, Didemnum speciosum and Didemnum granulatum. Three species are possibly new and will be described elsewhere. An additional nine are new records for the state of Paraná: Perophora regina, Didemnum speciosum, Trididemnum orbiculatum, Eudistoma carolinense, Aplidium pentatrema, Molgula phytophila, Botryllus tuberatus, Symplegma brakenhielmi and Polyandrocarpa anguinea. While all these species are distributed between 6 and 15 m, there is a tendency to reduction of abundance towards 15 m in several species. Some species appear to prefer the north side of the island. Several species show temporal changes in abundance, with some being most common in the spring and others in the summer, but we can not affirm yet that there is a seasonal pattern between years.

Abstract:

Algae is a phototrophic organism and is the primary and main food source of organic matter. They can originate organic matter from inorganic substances such as, dry plants. In the process of photosynthesis, they release O2 and absorb CO2 and make it possible for the entire marine animal population. Macrophytobenthos plays a crutial role in the coastal ecosystem of the Caspian Sea. Macrophytes and seaweed provide a sustainable flow of organic matter to heterotrophic organisms and create a plant biotope for invertebrates and phytophilic fish. The dynamics of aquatic vegetation mainly determines changes in benthic communities, their distribution and resources. The level of the Caspian Sea and its salinity determine the distribution of aquatic plants, phytobenthos and of course fluctuations and changes in the level of the Caspian Sea play an important role in the dynamics of aquatic vegetation.

Abstract:

The article presents the results of a study of the hydrological regime of the Ural river in the territory of the West Kazakhstan region, the average annual flow of the river, as well as the average decadal water levels during the spring flood. According to the presented results, there is a noticeable decrease in annual runoff, which directly has a negative impact on the local ichthyofauna of the reservoir. The decrease in the water level in the Ural river affects the efficiency of natural reproduction of phytophilic fish. In 2019, due to a decrease in the water content of the Ural river, carp fish, namely common carp, did not have the opportunity to spawn in floodplains and flood meadows of the river. When catching producers for the purpose of artificial reproduction, the spawning herd of common carp was represented by individuals aged from 5 to 12 years.

The taxonomic and eco-morphological diversity of amphibiotic insects in the ecosystems of the Latoritsa River basin was studied. Оf all 52 species of amphibiotic insects have been identified (32 species of Ephemeroptera, 7 species of stoneflies, 13 species of dragonflies). The main of the number and biomass of the community in the studied localities of the Latoritsa River basin is the families Baetidae and Heptageniidae. The rarity components of this region are investigated. The 3 types of Odonata, 5 types of Ephemeroptera and 3 types of Plecoptera larvae for Latoritsa river basin are discovered. The ecomorphological structure of dragonflies is represented by the following classes: rheophilic drifting and rheophilic velox larvae with spoonlike labium. The largest species diversity of the Ephemeroptera was recorded in 4 types of eco-morphs: siphlonuroides (47% from species diversity), plane-plots (32%), larvae with "tusks" (12%) and "kryshkovoziabrovi" larvae (9%). Among the Plecoptera there are 3 dominant type: lithophilous cryptobionts (42%), phytophilic cryptobionts (31%) and cryptobionts of gaps (27%).

Abstract:

This study examines the species composition, biodiversity, zoogeography, and ecology of freshwater gastropods of 12 springs in Andijan region of Uzbekistan. The study used generally accepted malacological, faunistic, ecological, analytical, and statistical methods. As a result of research in the springs, 14 species of freshwater gastropods belonging to 2 subclasses, 5 families, and 10 genera were recorded. 7 of them are endemic to Central Asia. When indicators of biodiversity of mollusks were analyzed according to the Shannon index, it was found that the highest value was recorded in the springs besides the hills. According to the biotope of distribution and bioecological features, they were divided into cryophilic, phytophilic, pelophilic, and eurybiontic ecological groups. The mollusks, which are common in the springs, were divided into 3 groups according to their faunal similarity. The contribution of the Central Asian and European-Siberian species to the formation of the malacofauna in the springs of the Andijan region was significant.

Abstract:

For the first time, data on the composition of cladoceran communities in lake bottom sediments from Bol’shoy Lyakhovsky Island and Oyogos Yar on the coast of the Dmitry Laptev Strait during the last major interglacial period (MIS 5e, 124-119 thousand years ago) have been obtained. 13 Cladocera taxa were identified in the composition of the taphocenoses. The composition of the Cladocera taphocenoses of Oyogos Yar indicates the presence of a well-developed littoral zone in the paleolakes, as most of the cladoceran remains belong to littoral-phytophilic taxa closely associated with macrophytes. In the Cladocera communities of Oyogos Yar, both cold-water representatives and more southern thermophilic taxa, such as Leydigia leydigi, were found. The findings of Cladocera remains from the MIS 5e period on the coast of the Laptev Sea, significantly north of their current ranges, allow for the reconstruction of warmer climatic conditions than those of today. The data obtained on Cladocera are well consistent with the results of chironomid analysis.

The paper presents the data of the study of the fauna of zooplankton communities of the hollows of the South-Belomorian mires (Arkhangelsk oblast), carried out in may-august 2021. The zooplankton of the hollows the mire Ilasskoye contains 37 species of planktonic invertebrates, including 15 species of rotifers, 18 species of cladocerans, and 4 species of copepods. The planktonic fauna is represented mainly by phytophilic, sphagnophilic, acidophilic species of rotifers and crustaceans. Differences in the species size of zooplankton depending on the level of watering of the hollows are revealed. The high rates of quantitative development are characteristic for the zooplankton communities (649.7 ± 53 thous. ind./m3; 4.36 ± 0.4 g/m3). The trophic structure of zoocenoses was dominated by secondary filtrators and verticators, among which the crawling-floating forms of cladocerae and rotifers prevailed, which indicates the predominant role of detritus in the circulation of substances and energy in water bodies of this type.

Abstract:

Exotic (introduced) species are a growing problem in ports worldwide and comprise the most important impacts in marine ecosystems. Periodic monitoring to detect introduced species is extremely important for effective population control. Here we sampled ascidian species near the port of Paranaguá for a taxonomic study of this fauna to attempt to detect introduced species. Larval stages in ascidians are short-lived, and dispersal is restricted to small distances, and so ascidians are very good bioindicators for exotic introductions due to ship transport. Four locations were sampled within Paranaguá Bay (Ilha das Cobras, Pier Tenenge, Ilha do Mel and Ilha da Galheta) and one location outside of the bay (Parque dos Meros). Information for the nearby fauna and for geographic distributions of the species involved was obtained from the literature. Eighteen species were found: Perophora multiclathrata (Sluiter, 1904), Ascidia curvata (Traustedt,1882), A. sydneiensis Stimpson, 1855, Clavelina oblonga Herdman, 1880, Cystodytes dellechiajei (Della Valle, 1877), Eudistoma carolinense van Name, 1945, Distaplia bermudensis van Name, 1902, Didemnum granulatum Tokioka, 1954, Diplosoma listerianum (Milne-Edwards, 1841), Lissoclinum fragile (van Name, 1902), Botryllus planus (van Name, 1902), B. tuberatus Ritter & Forsyth 1917, Botrylloides nigrum Herdman, 1886, Symplegma rubra Monniot, 1972, Styela canopus (Savigny, 1816), S. plicata (Lesueur, 1823), Microcosmus exasperatus Heller, 1878 and Molgula phytophila Monniot, 1970. The known geographic distributions based on the literature and collections suggest that three species are native, one is a inter-regional introduction, two are introduced from the Pacific and the remaining 12 are cryptogenic.

They are described and illustrated with the aid of conventional light microscopy and low temperature scanning electron microscopy. Females of both new species possess a distinct pregenital plate divided into two parts by a subcuticular medial ridge. Additionally, in S. karooensis n. sp. the movable digit of the male chelicerae varies in length: among six observed males, three males had a movable digit (md) twice shorter than the fixed digit (fd), in one male it was slightly shorter than fd and in the remaining two males md and fd were of the same length. An updated key to the world genera of the tribe Sierraphytoptini is given. The key incorporates data on seven sierraphytoptine genera including three genera (Neoprothrix Reis & Navia, Solenoplatilobus Chetverikov & Craemer and Solenocristus n. g.) which were described since the last generic key of Eriophyoidea by Amrine et al.

Abstract:

Interannual variation of the water level in Lake Khanka is considered on satellite altimetry data; its extreme rising in recent years is noted, with the maximum in 2016. Using a simple balance model, contribution of the main components of its water balance to the modern rise is determined, as precipitation in its basin, evaporation, and water discharge through the Sungacha River. Growth of summer precipitation is defined as the main reason of the level rising. However, the water income to the lake does not correlate with the precipitation volume since 2010 that confirms the hypothesis about artificial influence on the water balance of Lake Khanka by its connection with the Mulin River (China) and worsening of the outflow through the Sungacha. As the result, the lake got additionally about 1.3 km3 in 2014–2015 that promoted the level rise to the highest mark. But before and after this period, the water inflow was lower than its expected values, obviously because of its redistribution. Positive influence of the anomalous water level growth on total abundance of commercial fish species is shown. The high level is favorable for reproduction of phytophilic species (Cyprinus rubrofuscus), whereas abundance of pelagophilic species (Chanodichthys erythropterus) declines.

We reconstructed paleoclimatic and paleoenvironmental changes based on the analyses of sediments from the Lake Polevskoye on the Zaonezhsky Peninsula in northwestern Russia. The change in the taxonomic composition of chironomids was analysed in the studied core. The age of the sediments covers ca 7.1 thousand years. Based on the cluster analysis, 3 main stratigraphic zones were identified. From 7.1 to 5.2 ka cal. yrs. BP, phytophilic taxa associated with shallow lakes dominated. Later between 5.2 – 2.0 ka cal. yrs. BP chironomids biodiversity increased. During this period, cold-water taxa appeared, which might indicate some cooling during this period. There was also a simultaneous increased in the number of profundal and semi-terrestrial species, which may indicate the changes of the water level in the lake and paludification. After 2.0 ka cal. yrs. BP the total number of species decreased. The dominant taxa associated with shallow water levels and moderately warm climatic conditions. Changes in the taxonomic composition of chironomids in Lake Polevskoye responded to paleoenvironmental changes. During the studied period, there was an increase in diversity of chironomids and a change in dominant taxa. The reconstructed conditions showed an increase in the water level in the lake from 5.2 to 2.0 ka cal. yrs. BP, as well as a gradual increase in trophicity.

Abstract:

The effects of climate warming and eutrophication on aquatic organisms are well established, but we lack a deep understanding of the selective mechanisms of fish communities towards eutrophication and warming in tandem. The aim of the study was to identify fish traits that were positively related to eutrophication and ongoing warming. The research was conducted for 19 years in the Dnipro River channel and floodplain water system of the “Dnipro-Orylskiy” Nature Reserve. Both categorical and continuous fish traits were considered. The study area is characterized by a more intense warming trend than the average for Europe, which reflects an increase in the maximum summer air temperature. At the same time, the concentration of chlorophyll-a had a monotonic tendency to decrease during the study period. Phytophilic, limnophilic, and freshwater fish species are increasing in abundance, while rheophilic and lithophilic fish are decreasing due to global warming. Fish species with greater vulnerability and resilience have selective advantages in terms of global warming. Pelagic fish species are the most resistant to eutrophication, while benthopelagic and phytolithophilic fish species are the most sensitive. Brackish-water demersal self-settled species of marine origin have a competitive advantage over other native freshwater species in the face of increasing symptoms of eutrophication and a warming climate.

Purpose: to develop a technical justification of fish protection structures arranged as part of the Bagaevsky hydroelectric com-plex on the Don River. Materials and methods. The research was based on data on fish science, topographic, hydraulic and tech-nological conditions of the Bagaevsky hydroelectric complex. The methods of scientific analysis and technology of search design were used in the development of fish and security structures of the hydroelectric power plant. Results and discussion. The com-position, type, location and parameters of the fish protection facilities of the Bagaevsky hydroelectric complex have been estab-lished. A continuous fish-passing lock provides up to 16-20 cycles of attracting, accumulating and locking fish per day. The fish-spawning channel provides for the passage of fish with different swimming ability. Conditions for recreation and spawning of rheophilic and lithophilic fish species are formed in its tract, and phytophiles spawn in the ponds of the tract. Conclusions. 1. Tak-ing into account the fish-breeding significance and responsibility of the Bagaevsky hydroelectric complex, its technical solution provides for the creation of conditions for the passage and spawning of fish. 2. The adopted technical solutions for the construc-tion of a hydroelectric power plant, a fish-passing gateway, a fish-spawning channel and spawning ponds meet modern fish-breeding requirements and provide conditions for the natural reproduction of fish.

Abstract:

The article deals with clarifying the species composition of black currant (Ribes nigrum l.) pests in the Right-Bank Forest- Steppe of Ukraine. During 2005-2020, 29 species of phytophagous insects from 15 families of 7 series and 2 species of phytophagous mites (Cecidophyopsis ribis Westw., Tetranychus urticae Koch.) were found in black currant plantations. The largest part (29% of the total number of detected species) in the structure of insect pests was occupied by representatives of a number of beetles (Coleoptera, among which the most common and harmful is the agrilus (Agrilus viridis L. ab aubei C-C.). Pests of the lepidopterans (Lepidoptera) were represented by 7 species from 5 families and accounted for 24% of the structure of the harmful entomocomplex. The most harmful representatives of this series are the currant clearwing moth (Aegeria tipuliformis Cl. (Synanthedon tipuliformis Cl.)) and common currant tortrix (Pandemis ribeana Hb.). The part of the series of homopterans (Homoptera) in the structure of the phytophagous complex was 17%, which were represented by five species of pests of the family Aphididae (aphids), among which the aphid currant (Aphis schneideri Born) is dominant. Phytophagous insects from the series hemipterans (Hemiptera), hymenopterans (Hymenoptera), dipterans (Diptera) and orthopteroids (Orthoptera) were represented by only 1–4 species and had no economic significance in terms of population density and harmfulness. Two species of herbivorous mites were also identified: the currant bud (Cecidophyopsis ribis Westw.) and the common spider mite (Tetranychus urticae Koch.). In terms of trophic specialization, polyphagous insects dominated, and phytophiles (dendrobiots) dominated in life forms.

Abstract:

In commission of Rijkswaterstaat Directorate Limburg, a desk study was carried out by the OVB to assess whether fish species in the river Meuse are restricted in their abundance and distribution by the lack of appropriate spawning habitat. The area studied comprises the Dutch part of the river between Eijsden and Hedel, including old river arms and former gravel pits connected with the main stream. Not included in the study is the Grensmaas, a non-canalised stretch of the river. A total of 21 fish species were selected, whose habitat requirements regarding spawning and growth were collected by a literature survey. The assessment was made by relating habitat-associated factors (water depth, rate of flow, substratum, macrophytes) with fish-specific requirements on spawning and growth. Thus it was possible to assess per river section of 100 meters length its potential suitability as spawning and nursery area for 17 species. It was concluded that no potential spawning and nursery areas are available for barbel (Barbus barbus), chub (Leuciscus cephalus), nose carp (Chondrostoma nasus) and dace (Leuciscus leuciscus). The presence of these species in the study area can be explained by migration out of the Grensmaas. Only on 1.5 % of the total amount of river sections macrophytes are present, which obviously limits the possibilities for the phytophilic species pike (Esox lucius), tench (Tinca tinca), crucian carp (Carassius carassius), carp (Cyprinus carpio), bitterling (Rhode us sericeus amarus), white bream (Blicca bjoerkna) and rudd (Scardinius erythrophthalmus). For ide (Leuciscus idus), gudgeon (Gobio gobio), bleak (Alburnus alburnus), perch (Perca fluviatilis), pikeperch (Stizostedion hicioperca) and ruffe (Gymnocephalus cernua) potential spawning and nursery areas are abundantly present.

Abstract:

Background. A larvae of family Chironomidae are the most mass and widespread species of macrozoobenthos and play an important role in the lives of almost all types of reservoirs. They constitute a convenient model in the analysis of anthropogenic influences. Besides, chironomids have the largest polytene chromosomes in nature that allow carrying out cytogenetic analysis of the impact of various toxic substances on chromosomal aberrations. Materials and methods. The karyotype and chromosomal inversion polymorphism one of the species phytophilic chironomids Glyptotendipes glaucus (Meigen, 1818) from five reservoirs of Kaliningrad (ponds Chistyi and Mel’nichnyi, system of ponds Karasevka, lakes Pen’kovoe and Shkol’noe) was studied. Cytological mapping of chromosomes was performed by system of Belyanina and Durnova (1998). Results. The levels of natural inversion polymorphism for each populations were determined. Comparison of inversion polymorphism with early data for Saratov, Bryansk and Kaliningrad regions was carried. The preservation of tendencies of distribution and prevalence gomo-and heterozygotic inversions of glaB1.2, glaB2.2 and also consolidation in the karyofund of populations sequence glaA2 in the heterozygous state in ponds Karasevka and Chistyi was observed. The characteristic for an earlier research of populations Glyptotendipes glaucus of Kaliningrad the presence inversion sequences glaG4 and glaD2 is retained. The level of inversion polymorphism for reservoirs of Kaliningrad has decreased and has approached nearer to data for Bryansk and Saratov regions. Conclusion. Based on these results we can offer a working hypothesis of a direct dependence of value of chromosomal polymorphism on the level of pollution of reservoirs ions of heavy metals (Kaliningrad), long-living radionuclides (Bryansk region), nitrates and ions of ammoniac nitrogen (Saratov region).
