The author gives a new syntaxonomic classification of the phytocenoses included in the association <i>Myriophyllo-Nupharetum</i> described by W. Koch (1926) without any documentation material. After analysing 1554 phytosociological records from the territory of Poland, in which species considered as characteristic for <i>Myriophyllo-Nupharetum (Nuphar luteum, Nymphaea alba, N. candida</i> and <i>Myriophyllum verticillatum)</i> were the forming species (in this case also the dominating ones), it was considered necessary to classify these phytocenoses to three separate associations: <i>Nuphareto-Nymphaeetum albae, Nymphaeetum candidae</i> and <i>Myriophylletum verticillati</i>. A table representing the association <i>Nuphareto-Nymphaeetum albae</i>, 3 synthetic tables and maps of distribution of the so far recorded sites or groups of sites of the above

Streszczenie:
Le myriophylle à épis (Myriophyllum spicatum) est une plante vasculaire exotique envahissante qui colonise les lacs et les rivières de l’Amérique du Nord depuis plusieurs décennies. Nous avons reconstitué la progression historique de son invasion au Québec à l’aide de spécimens d’herbier, de bases de données, de rapports, de journaux et de périodiques. L’aire de répartition de la plante s’est beaucoup étendue depuis son introduction à la fin des années 1950. L’espèce s’est d’abord disséminée le long du fleuve Saint-Laurent. Elle s’est ensuite propagée à l’intérieur des terres à partir des années 1970. En 2017, 14 des 17 régions administratives du Québec comptaient au moins une mention de myriophylle à épis. Cela représentait 132 lacs, 16 rivières et ruisseaux — y compris le fleuve Saint-Laurent et ses lacs fluviaux — et 4 autres plans d’eau, tels que des étangs ou des voies navigables artificielles. À lui seul, le fleuve Saint-Laurent représentait 24 % des 322 mentions. Les régions avec le plus grand nombre de mentions sont celles de la Montérégie, des Laurentides, de l’Estrie et de l’Outaouais. Bien que l’envahissement par le myriophylle à épis semble avoir progressé de manière importante ces dernières années, il est possible que l’augmentation du nombre d’observations soit davantage le reflet d’une préoccupation grandissante des acteurs du territoire par rapport à l’envahisseur que d’une accélération réelle de l’invasion.

In this study, Myriophyllum was used to remove Congo Red dye from wastewater. The influence of operation factors include illumination intensity, initial pH, biomass and dye concentration on the degradation rate of Congo Red were investigated. The experimental results demonstrated that Myriophyllum can effectively degradate Congo red dye. The Congo red dye was almost completely discolored in 10 days under the conditions of 5000 lx of illumination density, 7.5 of pH, 15g /L~17.5 g/L of initial biomass and less than 20 mg/L of Congo red concentration. Furthermore, the great reduction of intermediate products and COD indicated that biodegradation of Congo red dye with Myriophyllum not only produced less secondary pollution, but also mineralized azo dye into inorganic matters. Myriophyllum in pollutants degradation presented obvious technical advantages and environmental benefits.

AbstractSpinasterol (1) and four flavonoids (2‐5) were isolated from Albizia myriophylla wood collected at Phu Yen province, Vietnam. The chemical structures of these compounds were elucidated by NMR spectroscopy as well as compared with data in the literature. The contents of some high yield isolated compounds (2‐4) in the ethanol extract of A. myriophylla were quantified by high‐performance liquid chromatography. These HPLC chromatograms could be used to reveal the presence of isolated compounds as markers of the sample.

The jute mattings of two different densities were tested to control growth of Elodea canadensis Michx. and Myriophyllum spicatum L. in the Velký Bolevecký pond (West Bohemia, Czechia) during fourteen months. Both jute densities prove to be effective, permeable and stayed intact for one year. Results showed significant interaction among species, jute density and date in both abundance and length of Elodea and Myriophyllum fragments. When tested separately, we found the significant difference between abundance of Elodea and Myriophyllum fragments on the jute mattings, among the sites, and in time, but not between the two jute densities. Elodea dominated the sites due to spread of fragments from mowing that continued at the pond. However, the fragment length of given species varied between the two jute densities. They might easier root, but it could be also explained by the variability of sampled quadrats. Fragment lengths of Elodea and Myriophyllum were also changing in time but the length did not significantly differ between the two species or among the sites. Although Elodea and Myriophyllum dominated the jute mattings by the end, their progress was slower than in control sites.

Streszczenie:
Scleractinian coral faunas from the upper Berriasian part of the Oehrli Formation of western Austria (Vorarlberg) and eastern Switzerland (Canton of Appenzell) are taxonomically described for the first time. Furthermore, scleractinian corals of the upper Berriasian part of the Oehrli Formation of the Swiss Cantons of Nidwalden and Uri are revised based on the study of type material. Lectotypes are designated for the species Dimorphocoeniopsis alpina (Koby, 1896) and Pleurophyllia tobleri (Koby, 1896). Sixty-one species belonging to 43 genera and 18 families were identified, making the coral fauna of the upper Oehrli Formation by far the most diverse among the Berriasian assemblages: Actinastrea pseudominima (Koby), A. sp., Adelocoenia bulgarica (Toula)(new combination), A. hexaphyllia (d’Orbigny)(new combination), A. radisensis (d’Orbigny)(new combination), Allocoeniopsis luciensis (d’Orbigny), Amphiaulastrea sp., Astraeofungia cf. decipiens (Michelin), Cladophyllia conybearei Milne Edwards & Haime, Columnocoenia ksiazkiewiczi Morycowa, Comoseris jireceki Toula, Complexastrea seriata Turnšek, C. lobata Geyer, Cycloria mariscali (Felix)(new combination), Dermosmilia capitata (Koby), D. simplex Koby, Dimorphastrea excavata d’Orbigny, D. explanata De Fromentel, Dimorphocoeniopsis alpina (Koby), Ellipsocoenia lorioli (Koby), Enallhelia compressa (Münster), E. rathieri d’Orbigny, Epistreptophyllum cf. densum Roniewicz, Fungiastraea moeschi (Koby), Heliocoenia corallina Koby, H. humberti Étallon, H. minima Sikharulidze, Heterocoenia cf. inflexa (Eichwald), Latiphyllia neocomiensis De Fromentel, Latiastrea mucronata Sikharulidze, Latomeandra sp., Meandrastrea rudis (De Fromentel)(new combination), M. cf. lamberti (Bataller), Meandrophyllia corrugata (Michelin), Microsolena major (Ferry), M. cf. subexcavata Eguchi, Mitrodendron cf. modicum Eliášová, Mixastraea polyseptata Morycowa, Montlivaltia arcuata Beauvais, M. kaufmanni Koby, M. truncata (Defrance, 1817), Myriophyllia cf. propria Sikharulidze, Paraclausastrea vorarlbergensis Baron-Szabo, Peplosmilia stutzi (Koby), Placocoenia heimi (Koby)(new combination), Placophyllia dianthus (Goldfuss), Plesiomontlivaltia paucisepta (Koby)(new combination), Pleurophyllia schmidti (Koby)(new combination), P. tobleri (Koby), Polyphylloseris icaunensis (d’Orbigny, 1850), Rhipidogyra cf. minima Koby, Stylangia cf. laddi Wells, Stylina pleionantha Meneghini, S. decipiens Étallon, S. cf. sparsa Trautschold, Stylosmilia alpina Koby, S. yabei Eguchi, Thecosmilia dichotoma (Koby), Th. sp., Trigerastraea gourdani (De Fromentel), and Vallimeandra cf. explanata (De Fromentel). Furthermore, five additional Berriasian coral faunas are reviewed and compared with the coral fauna of the upper Oehrli Formation. These five assemblages are from southern Ukraine (2 assemblages, consisting of five and 12 species, respectively), northern Tunisia (13 species), southern Spain (23 species), and central Tibet (11 species). Except for the faunas from central Tibet and northern Tunisia, the Berriasian coral assemblages are distinctly dominated by colonial species (70–95%); they represent largely isolated populations of mostly endemic species; and consist largely of genera that had already appeared in the Upper Jurassic (80–100%). On the species-level, however, with the exception of the coral assemblage of Spain, the Beriasian coral faunas are dominated by or completely consist of taxa that have their first occurrence in the Berriasian (54–100%). The Berriasian fauna of the upper Oehrli Formation described in this work contains nearly three times more species than found in the contemporaneous fauna of southern Spain which up to now was the largest known Berriasian fauna. Two of the upper Berriasian taxa described in the current work (Cycloria and Placocoenia) may be the first representatives of lineages that still occur today (Mussidae and Montastraeidae, respectively) as suggested by a recent study of the cox1 Intron in modern corals.

Testovima inhibicije rasta M. aquaticumi  M. spicatum  u voda-sediment sistemu ispitana je osetljivost i mogućnost primenemetode u preventivnoj proceni rizika od herbicida i regulatora rasta.    Deo rezultata dobijenih u radu uključen je u završne izveštaje internacionalnihtestova interkalibracije metoda,  a kao rezultat ovih aktivnosti usvojene su novestandardne metode na ukorenjenim akvatičnim makrofitama ISO 16191/2013 i OECD 239/2014.      Na osnovu istraživanja, zaključeno je da je kontaktni test toksičnostisedimenta  jednostavan i lak za izvođenje, kao i da je vrsta  M. aquaticum  u jedno-komponentnom sistemu (sediment)  adekvatan test model. Rastom kontrolnih biljaka, niskom varijabilnošću i visokom osetljivošću bioloških  odgovora zadovoljen je kriterijum validnosti testa. Preporučeno je korišćenje dodatne kontrole  u  slučajevima kada postoje značajna odstupanja u strukturi između  standardnog sintetičkog kontrolnog i  testiranog prirodnog sedimenta.  Kontaktnim  testom toksičnosti sedimenta obogaćenog  atrazinom  pokazano je da se ovaj test  može smatrati potencijalno dobrom metodom za proširenje ekološke procene rizika od hemikalija koje pokazuju afinitet vezivanja za sediment.    Ispitivanjem potencijala  testa  inhibicije rasta vrsta roda  Myriophyllum  u voda-sediment sistemu  utvrđeno je da su testovi  izvodljivi u praksi, da pokazuju  visoki stepen stabilnosti, statističku snagu i malu varijabilnost  većine  ispitivanih parametara rasta. Poređenjem testova sa vrstama  M. aquaticum  i  M. spicatum, nije utvrđena značajna  razlika u osetljivosti na odabrane herbicide.  Osetljivost  testova na vrstama roda  Myriophyllum  i standardnih  Lemna  testova je bila slična,  osim u slučaju auksin simulatora gde su  vrste roda Myriophyllum  sp. bile osetljivije,  što  ukazuje  na njihovu primenljivost u proceni rizika od pesticida specifičnog mehanizma toksičnog dejstva.    Iako  obe vrste roda  Myriophyllum  imaju  prednosti i nedostatke  kao testorganizmi,  vrste se  mogu  smatrati reprezentativnim akvatičnim ukorenjenimmakrofitama i predstavljati  adekvatne  dopunske test vrste u višim nivoima ekološkeprocene rizika od herbicida i regulatora rasta.  Takođe, vrsta M. aquaticum  je pogodna za  testiranje u  različitim test sistemima,  a samim tim  ima i veći  potencijal primene u preventivnoj, ali i retrospektivnoj ekološkoj proceni rizika.
Growth inhibition tests on Myriophyllum  aquaticum  (Vell.) Verd.  and Myriophyllum spicatum  L.  were conducted in order to assess their use in refined risk assessment  of chemicals, as well as in  sediment  risk assessment.  The applicability, stability and sensitivity of the  M.  aquaticum  sediment contact test on natural sediments (from rivers Tamiš, Krivaja and  Jegrička) was assessed for use in retrospective ecological risk assessment (ERA). The potential use of the spiked sediment contact test in risk assessment  of  sediment bound chemicals was  also investigated. The sensitivity and applicability of the growth inhibition tests on  M. aquaticum  and  Myriophyllum spicatum  in a water-sediment system was assessed for potential use in prospective ERA of plant protection products.A part of the results of this study was included in the final report of the two  international ring tests, which resulted with new standardised methods with rooted macrophytes:  ISO 16191/2013 i  OECD  239/2014. Tests on  Myriophyllum  species were compared to standard Lemna  tests.  Test substances in M. aquaticum  and  Lemna minor  L. tests were 3,5 dichlorphenol, atrazine, isoproturon, trifluralin, 2,4 D and dicamba, while substances used in  M. spicatum  tests were atrazine, isoproturon and 2,4 D.The sediment contact test proved to be simple and robust, while M. aquaticum can be considered as an adequate test model in a one-compartment (sediment) test. The validity criteria regarding control plant growth and variability was met. The use of an additional control is suggested when testing of sediments with considerably different properties of the standard synthetic control is taking place.  The spiked sediment contact tests with atrazine showed that the method could be applied in prospective risk assessment of sediment bound chemicals.The water-sediment growth inhibition test with  Myriophyllum  species proved to be applicable in practice, with high stability, statistical power and low variability of the majority of the growth parameters.  M. aquaticum  and  M. spicatum  didn’t show major  differences  in sensitivity to tested substance.  The sensitivity of  Myriophyllum and  Lemna  tests was also similar, except to auxin simulators, where  Myriophyllum species were considerably more sensitive, which makes them adequate  candidates for use in risk assessment of chemicals with specific mode of action.Even though both  Myriophyllum  species show advantages and disadvantages as test organisms, they can be regarded as representative rooted aquatic macrophyte species and additional test species in refined risk assessment of herbicides and growth regulators.  Also,  M. aquaticum  can be tested in various test syytems, which makes this species  applicable in prospective as well as retrospective ecological risk assessment.

"Evaluation de la biodisponibilité du cuivre dans des sédiments artificiels par des méthodes biologiques avec la plante aquatique Myriophyllum aquaticum (hydroponie, biotest normalisé et Rhizotest) et géochimiques (DGT)".

Streszczenie:
Les travaux menés durant cette thèse ont visé à évaluer la pertinence de la plante aquatique Myriophyllum aquaticum pour l'étude de la biodisponibilité du cuivre dans des sédiments ainsi que l'intérêt de la technique du gradient de diffusion en couche mince (DGT) comme outil biomimétique de cette plante. Une première expérimentation réalisée avec la plante M.aquaticum exposée selon le protocole du biotest normalisé (sous forme de verticilles) dans des sédiments artificiels dopés en cuivre a montré que ce biotest semble être un outil intéressant pour l'évaluation de la toxicité de sédiments contaminés en cuivre. En outre, aucune corrélation n'a été observée entre les mesures DGT et la bioaccumulation dans la plante M.aquaticum. Ceci est probablement lié aux conditions d'exposition des plantes. En effet, le développement des racines se faisant au cours de l'expérimentation, les processus d'incorporation du métal dans la plante ne sont donc pas constants au cours de l'expérience. Suite à ces résultats nous avons réalisé deux autres séries d'expérimentations (hydroponie et Rhizotest) dans lesquelles, les plantes ont été exposées selon un protocole modifié (plantes ayant déjà développé des racines avant leur exposition dans le sédiment). Ces expérimentations nous ont permis de montrer que la plante M.aquaticum est plutôt sensible au cuivre et qu'elle a une forte capacité à l'accumuler. De plus, les résultats obtenus ont permis de montrer que la technique DGT semble être un bon outil biomimétique de cette plante dans le cas où elle est exposée avec des racines car le prélèvement par la plante est limité par la capacité de la phase solide à réapprovisionner le métal en solution
The work carried out during this thesis aimed to assess the relevance of the aquatic plant Myriophyllum aquaticum to study the bioavailability of copper in sediments as well as the interest of the technique of diffusion gradient in thin film (DGT) as a biomimetic tool of this plant. A first experiment, performed with the plant M.aquaticum exposed according to the protocol of the standardized bioassay (as whorls) in an artificial sediment spiked with copper, showed that this bioassay appears to be a useful tool for assessing the toxicity of contaminated sediments copper. Furthermore, no correlation was observed between DGT measurements and bioaccumulation in the M.aquaticum plant. This is probably due to the exposure conditions of the plants. In fact, as the root development occurs during the experiment, the process of incorporating the metal into the plant is therefore not constant throughout the experiment.Following these results we conducted two other series of experiments (hydropony and Rhizotest) in which, plants were exposed following a modified protocol (plants having already developed roots before their exposure in the sediment). These experiments showed that the plant M.aquaticum is rather sensitive to copper and has a strong ability to accumulate it. Futhermore, the results have shown that the DGT technique seems to be a good biomimetic tool for this plant when it is exposed by roots because the plant uptake is limited by the capacity of the solid phase to replenish the metal in solution

Streszczenie:
Le but de ce travail de thèse est de démontrer l’intérêt d’un macrophyte aquatique submergé, Myriophyllum alterniflorum pour la détection de contaminants dans l’environnement. Des études in situ ont été réalisées pendant 28 jours sur cinq milieux aquatiques, affectés par différents types de pression anthropique, durant trois campagnes de terrain (printemps 2015, automne 2015 et printemps 2016), pour déterminer si l’accumulation des contaminants dans la plante et si des biomarqueurs du myriophylle peuvent être utilisés pour détecter la présence de contaminants dans les eaux. L’accumulation des contaminants au cours du temps était corrélée avec les teneurs des contaminants dans l’eau ; l’influence de la durée d’exposition a été étudiée. Au cours des trois campagnes, la réponse des biomarqueurs, teneur en MDA et activité de nitrate réductase était corrélée avec les teneurs en contaminants dans l’eau et dans la plante ; cependant l’influence de la durée d’exposition sur l’évolution de la réponse des biomarqueurs est moindre par rapport à celle de l’accumulation des contaminants. Ainsi, l’étude des biomarqueurs pourrait permettre une évaluation plus fiable de la qualité des masses d’eau que le suivi de l’accumulation dans la plante. Au cours de la campagne printemps 2015, un panel de biomarqueurs plus large a été étudié afin de définir les biomarqueurs les plus pertinents pour détecter spécifiquement les pressions liées aux activités urbaines ou industrielles. Une méthodologie d’évaluation de la qualité des eaux est proposée, en considérant un protocole d’analyse des biomarqueurs : un premier dosage de Chlb et MDA est simple et moins coûteux. Quand aucune preuve d'impact anthropique n'est montrée, aucune analyse complémentaire n'est requise. En revanche, lorsqu’une altération est mise en évidence, l’analyse d'autres biomarqueurs plus spécifiques tels que les activités G6PDH et γ-GCS sera nécessaire. La réponse de l'activité γ-GCS est spécifique du stress métallique, ainsi, la réponse de ce biomarqueur devrait amener à réaliser l’analyse des métaux/métalloïdes dans M. alterniflorum
The aim of this thesis is to demonstrate the interest of a submerged aquatic macrophyte, Myriophyllum alterniflorum for the detection of contaminants in the environment. In situ studies were conducted over 28 days in five aquatic environments, affected by different levels of anthropogenic pressure, during three field seasons (spring 2015, autumn 2015 and spring 2016), to determine whether the accumulation of contaminants in the plant and whether biomarkers can be used to detect the presence of contaminants in water. The accumulation of contaminants over time was correlated with the levels of contaminants in the water; the influence of the duration of exposure has been studied. In all three campaigns, biomarker response, MDA content, and nitrate reductase activity were correlated with contaminant levels in water and in the plant; however, the influence of the duration of exposure on the evolution of the biomarker response is lower compared to the accumulation of contaminants. Thus, the study of biomarkers could allow a more reliable assessment of the quality of water bodies than the monitoring of contaminant accumulation in the plant. During the spring 2015 campaign, a much broader biomarker panel was investigated to define the most relevant biomarkers for assessing water quality. A methodology for evaluating water quality is proposed, considering a biomarker analysis protocol: a first assay of Chlb and MDA is simple and less expensive. When no evidence of human impact is shown, no further analysis is required. On the other hand, when an alteration is highlighted, the analysis of other more specific biomarkers such as G6PDH and γ-GCS activities will be necessary. The response of γ-GCS activity is specific for metal stress, so the response of this biomarker should lead to the analysis of metals / metalloids in M. alterniflorum

Streszczenie:
Although capable of sexual reproduction, many plants also rely heavily on clonal reproduction. The formation of multiple, physiologically-independent units with the same genotype has important implications for spatial genetic structure and genetic diversity in these plants. The endangered scrub-dwelling perennial, Polygonella myriophylla is known to reproduce both sexually and clonally but no study to date has been able to investigate the spatial genetic patterns that occur in this species. I use microsatellite markers to investigate questions about clonal structure and genetic diversity in five populations of P. myriophylla and address some of the implications of my findings for conservation of this species: Overall, I find that 57% of sampled clusters of P. myriophylla are composed of a single genet (genetic individual) with multiple physiological units (ramets) while the remainder are made up of two or more genets. I found differences in both clonal reproduction and genetic diversity among populations. I also found evidence of limited gene flow even over small spatial scales (less than 10 km) and for at least 4 genetic clusters occurring within the species range. Despite high levels of genetic diversity overall, there is evidence of reduced genetic diversity in two populations My results suggest that high levels of clonality may be important in maintaining genetic diversity in P. myriophylla. I also provide evidence that dirt roadsides may not represent a refuge for this species.

Limitations from reduced light and increasing water depth on Nelumbo lutea seedlings were determined in tank experiments. Survival was high in all tested light levels. Total biomass increased significantly with increasing light. Biomass allocation shifted significantly to root production between 3 and 6 weeks in the 10 and 24% levels. Survival decreased with increasing planting depth, and biomass of survivors reduced significantly between 0.5, 1.0, and 1.5 m depths. Nelumbo lutea and Myriophyllum spicatum populations were monitored for one season in a 0.7 ha pond to track changes in species dominance. Myriophyllum spicatum dominated early, and N. lutea dominated from July through October, suppressing M. spicatum at all depths. Competitive interactions between N. lutea and M. spicatum were investigated for two seasons in a container experiment situated within a pond. Where established, N. lutea dominated in the presence of M. spicatum. However, N. lutea could not be established in depths greater than 1 meter.

Streszczenie:
Macroinvertebrate communities inhabiting an exotic, Myriophyllum spicatum, and a native, Heteranthera dubia macrophyte were studied from March 1999 to June 2000 in experimental ponds. Although macrophyte architecture explained some variation in macroinvertebrate abundance between the two macrophytes, most variation was explained by the sampling months. Total number of macroinvertebrates was found to be positively correlated with epiphyton biomass which differed significantly between the two plant types and among sampling months. Taxa richness did not vary between the two plant types. Chironomid larvae were the most abundant organisms and dominated by Apedilum elachistus on both plant communities. Annual production of five chironomid species was estimated by the size-frequency method. Production estimates (P) in g dry wt m-2 yr-1 of plant surface area for the predator Tanypodinae larvae were: Larsia decolarata, P= 0.77 and 0.67, Labrundinia virescens, P= 0.59 and 0.35 on M. spicatum and H. dubia, respectively. Larvae of Cricotopus sylvestris and Psectrocladius vernalis were collected from M. spicatum from March to mid-June. Production of C. sylvestris was found to be 0.46 g dry wt m-2, whereas it was 0.07 g dry wt m-2 for P. vernalis for this period. Apedilum elachistus exhibited the highest productivity: 9.9 g dry wt m-2 yr-1 of plant surface area on M. spicatum, and 8.5 g dry wt m-2 yr-1 on H. dubia. These production estimates are among the highest production values reported for a single species. Additionally, post-ovipositing development times for five chironomid species collected from Myriophyllum and Heteranthera were determined. Three different temperatures (15°, 20° and 25°C) were chosen to rear eggs under 12L: 12D photoperiod. Egg development times ranged between 1-4 days. Larval development times ranged from 44 days at 20°C for Tanypus neopunctipennis to as few as 9 days at 20°C for Larsia decolorata.

In order to investigate the habitat of the strictly protected species Umbra krameria, in the localities that should enter the new boundaries of the reserve, during 2023, an inventory and composition of flora and vegetation was made. The focus of these researches are macrophytic species. Five canals were processed (the properties Bela ćuprija; Ulmi duđ; Gradska šuma; Crna bara and Ćinkina ćuprija). A total of 42 species of plants were recorded, where cosmopolitan eurivalent species dominate. Important species are the rarer species Sparganium erectum ssp.neglectum and the strictly protected species Thelypteris palustris (Lolalita Crna bara). Of the total number of plants present, four species are non- native with an invasive character (Amorpha fruticose, Aster lanceolatum, Cyperus odoratus and Populus euroamericana). A total of 15 vegetation communities were recorded, seven of which were aquatic (Lemna minoris-Spirodeletum polyrrhizae W. Koch 1954; Lemnetum trisulca Knapp et.

Current dam discharge patterns in Noxon Rapids Reservoir reduce concentration and exposure times (CET) of herbicides used for aquatic plant management. Herbicide applications during periods of low dam discharge may increase herbicide CETs and improve efficacy. Applications of rhodamine WT dye were monitored under peak (736 to 765 m³ s⁻¹) and minimum (1.4 to 2.8 m³ s⁻¹) dam discharge patterns to quantify water-exchange processes. Whole-plot dye half-life under minimal discharge was 33 h, a 15-fold increase compared with the dye treatment during peak discharge. Triclopyr concentrations measured during minimum discharge within the treated plot ranged from 214 ± 25 to 1,243 ± 36 μgL⁻¹ from 0 to 48 h after treatment (HAT), respectively. Endothall concentrations measured during minimum discharge in the same plot ranged from 164 ± 78 to 2,195 ± 1,043 μgL⁻¹ from 0 to 48 HAT, respectively. Eurasian watermilfoil (Myriophyllum spicatum L.) occurrence in the treatment plot was 66%, 8%, and 14% during pretreatment, 5 wk after treatment (WAT), and 52 WAT, respectively. Myriophyllum spicatum occurrence in the nontreated plot was 68%, 71%, and 83% during pre-treatment, 5 WAT, and 52 WAT, respectively. Curlyleaf pondweed (Potamogeton crispus L.) occurrence in the treatment plot was 29%, 0%, and 97% during pretreatment, 5 WAT, and 52 WAT, respectively. Potamogeton crispus increased from 24% to 83% at 0 WAT to 52 WAT, respectively, in the nontreated plot. Native species richness declined from 3.3 species per point to 2.1 in the treatment plot in the year of treatment but returned to pretreatment numbers by 52 WAT. Native species richness did not change during the study in the nontreated reference plot. Herbicide applications during periods of low flow can increase CETs and improve control, whereas applications during times of high-water flow would shorten CETs and could result in reduced treatment efficacy.

Streszczenie:
Herbicide selection is key to efficiently managing nuisance vegetation in our nation’s waterways. After selecting the active ingredient, there still remains multiple proprietary and generic products to choose from. Recent small-scale research has been conducted to compare the efficacy of these herbicides against floating and emergent species. Therefore, a series of mesocosm and growth chamber trials were conducted to evaluate subsurface applications of the following herbicides against submersed plants: diquat versus coontail (Ceratophyllum demersum L.), hydrilla (Hydrilla verticillata L.f. Royle), southern naiad (Najas guadalupensis (Sprengel) Magnus), and Eurasian watermilfoil (Myriophyllum spicatum L.); flumioxazin versus coontail, hydrilla, and Eurasian watermilfoil; and triclopyr against Eurasian watermilfoil. All active ingredients were applied at concentrations commonly used to manage these species in public waters. Visually, all herbicides within a particular active ingredient performed similarly with regard to the onset and severity of injury symptoms throughout the trials. All trials, except diquat versus Eurasian watermilfoil, resulted in no differences in efficacy among the 14 proprietary and generic herbicides tested, and all herbicides provided 43%–100% control, regardless of active ingredient and trial. Under mesocosm and growth chamber conditions, the majority of the generic and proprietary herbicides evaluated against submersed plants provided similar control.

Streszczenie:
Lake Arakhley is located within the Lake Baikal basin in Eastern Siberia, Russia. The area is characterized by continental subarctic climate with considerate diurnal temperature range, long cold dry winters and short hot summers with more precipitation occurring during the latter half of the summer. Climatic shifts in high water years and low water years result in morphometric changes in the lake and in the chemical and physical parameters of the ecosystem. During low water years, concentrations of ammonium nitrogen and nitrite nitrogen are decreased, whereas nitrate concentration increases. High water years feature average concentrations of ammonium ions 1.5–2 times higher than the values of recent dry years. Redundancy analysis (RDA) of abiotic factors and biotic community indicated that the community structure shows the greatest correlation with physical and chemical parameters of water and biogenic elements (nitrites, ammonium, phosphates) along the first axis, and with the lake depth and transparency along the second axis. Changes in abiotic factors induce functioning and formation of characteristic communities of the primary producers in the trophic structure of the ecosystem. During low water years, with increased level of autochthonous organic matter, Lindavia comta dominance is observed, while during high water years, with increased allochthonous organic matter Asterionella formosa appeared as dominant. Currently, during low water years, the hydrophytes community is monodominant and composed of Ceratophyllum demersum. Meanwhile, such species indicating eutrophic conditions as Myriophyllum sibiricum, Potamogeton pectinatus are found in the lake vegetation.
