  • Is The invasive amphipod Dikerogammarus villosus the main factor
           structuring the benthic community across different types of water bodies
           in the River Rhine system'
    • Abstract: Publication date: July 2018Source: Limnologica, Volume 71Author(s): Meike Koester, Maximilian Schneider, Claudia Hellmann, Jochen Becker, Carola Winkelmann, René GergsAbstractDikerogammarus villosus, one of the most successful invaders in European river systems, is commonly regarded as a threat to native biodiversity and a main factor structuring the benthic community of invaded systems. The impact of D. villosus has been intensively studied in small-scale experiments and field observations, but its impact on natural communities on a larger scale remains unclear. Here, we investigated the benthic community structure at ten sites covering a broad range of habitats along the River Rhine (Central Europe) and its tributaries, to determine whether D. villosus is one of the main factors structuring the benthic community. Community composition was analysed using non-metric multidimensional scaling, distance-based redundancy analysis, and correlation analyses. D. villosus was one of nine relevant taxa present that altogether reflected a large part of the variation in the benthic samples, but further analyses indicated that the species might be less important for the community structure than other relevant taxa. Moreover, all nine relevant taxa together can explain only a similar amount of variation in our samples than the five relevant non-faunal environmental factors (water temperature, pH, conductivity, percentage of medium-sized gravel and macrophytes). Overall, our results suggested that rather a combination of non-faunal environmental factors than D. villosus mainly structure the benthic community composition on this larger spatial scale.
       
  • Biological impact assessment of sewage outfalls in the urbanized area of
           the Cuenca River basin (Ecuador) in two different seasons
    • Abstract: Publication date: July 2018Source: Limnologica, Volume 71Author(s): Rubén Jerves-Cobo, Koen Lock, Jana Van Butsel, Guilermina Pauta, Félipe Cisneros, Ingmar Nopens, Peter L.M. GoethalsAbstractWe evaluated the biological water quality in relation to chemicals discharged through sewage outfall during both dry and rainy season. The lowland area of the Cuenca River basin in the southern Andes of Ecuador, including the city of Cuenca, constituted the study area. To perform an integrated water quality assessment, data were collected of macroinvertebrates, physicochemical conditions and morphological characteristics in 43 sites in the Cuenca River and its tributaries. The Andean Biotic Index (ABI) and the Biological Monitoring Working Party adapted to Colombia (BMWP-Col) were used to evaluate the biological water quality. Both biological indexes were higher upstream than downstream from the city. Moreover, these indexes indicated better conditions during the rainy season than in the dry season, based on the presence of more sensitive families. The biological indexes related more to the oxygen saturation than to the five-day biological oxygen demand (BOD5), nutrients and chloride concentrations. The relationship between BOD5 and nutrient concentrations with the variation of both biological indexes was clearer in the dry season than in the rainy season. However, in some sites, these indexes were influenced more by morphological aspects than by pollutants. Both biological indexes showed similar patterns along the rivers, generally the BMWP-Col scored higher than the ABI index. The latter index was shown to be more suitable for the high Andes region. These results could be used to support the implementation of river restoration actions, such as determining priorities for splitting sewer and precipitation water transport systems and needs for improved wastewater treatment facilities in specific locations.
       
  • Population dynamics of the invasive freshwater shrimp Neocaridina davidi
           in the thermally polluted Gillbach stream (North Rhine-Westphalia,
           Germany)
    • Abstract: Publication date: July 2018Source: Limnologica, Volume 71Author(s): Gerhard Schoolmann, Hartmut ArndtAbstractOrnamental species of the aquarium pet trade contribute more and more to the introduction of previously exotic species in Europe. Among these, freshwater crustaceans play an increasingly larger role. Especially in thermally altered streams they may become invasive; however, field data on population ecology of invasive crustaceans are very rare. The aim of this study was to analyze the population dynamics of the invasive freshwater shrimp Neocaridina davidi (indigenous to China and other Asian countries) in a year-round warm-water habitat in the Gillbach stream (North Rhine-Westphalia, Germany), where this species forms a stable population. The species reached abundances between 0.23–1.39 individuals per m². N. davidi is highly productive and detectable in the whole Gillbach stream and in the lower Erft River, too. Egg ratio and cohort development were documented for a period of 27 months. Among adults, between 45 and 59% were females (average 50.5%). Life span was about 12 months in the field and up to 21 months under laboratory conditions. Development times under field and laboratory conditions were similar, ovigerous females appeared about 7 months after hatching. The population in the Gillbach stream was multivoltine with about two generations per year. Only 2–3% of eggs reached adulthood in the field most probably due to intensive predation by indigenous and invasive fish species. One specimen could already be detected in the Lower River Rhine. N. davidi is omnivorous and well adapted to different freshwater habitats. The risk of further spreading to other European river systems is obvious.
       
  • The relationship between river types and land cover in riparian zones
    • Abstract: Publication date: July 2018Source: Limnologica, Volume 71Author(s): Kateřina Kujanová, Milada Matoušková, Zdeněk HošekAbstractFluvial systems are dynamic and the characteristics of every assessed reach are variable and difficult to quantify based on river type threshold values. The authors of this study considered whether taking into account detailed land cover data from the riparian zone could be of any help in more accurately defining river types and establishing hydromorphological reference conditions. Detailed land cover data from riparian zones (50 m and 200 m buffers along main rivers) were included among the hydromorphological characteristics of the main rivers on the territory of the Czech Republic, and the relationship between established river types and land cover in riparian zones was evaluated.Land cover data from main river reaches categorized by river type indicate fundamental land cover differences between types that closely correspond with the hydromorphological characteristics of channels. If we examine riparian zones with no or minimal anthropogenic impact, significant land cover classes emerge for distinct river types that at the same time facilitate more accurate descriptions of river types. For rivers in agricultural lowlands, land cover contributes to revealing modifications of the river network. This study demonstrates that detailed land cover data can be used to explain differences between river types and can be included among river characteristics for establishing hydromorphological reference conditions or for assessing the level of anthropogenic impact in the riparian zone, which generally has an effect on the channel as well. At the same time, detailed land cover data may significantly help locate new reference sites, or exclude unsuitable sites.
       
  • Zooplankton assemblage in four temperate shallow waterbodies in
           association with habitat heterogeneity and alternative states
    • Abstract: Publication date: Available online 28 June 2018Source: LimnologicaAuthor(s): Maria Špoljar, Tvrtko Dražina, Jasna Lajtner, Maja Duić Sertić, Ines Radanović, Robert L. Wallace, Daniel Matulić, Tea TomljanovićAbstractWe assessed the zooplankton assemblages in four temperate shallow waterbodies differing in macrophyte coverage and alternative states: transparent vs. turbid. The main objectives of this study were: (i) to determine the horizontal assemblage of zooplankton in structurally different habitats; (ii) to examine the role of fish, macroinvertebrates and environmental conditions in the observed zooplankton assemblage patterns; and (iii) to evaluate the zooplankton-macroinvertebrate-fish food web interactions in pelagial and littoral zone in transparent vs. turbid lakes. Abiotic factors and food resources, as well as zooplankton assemblage did not show significant difference along the gradient of habitat complexity, but exhibited pronounced variability among these waterbodies. Selected lakes contained nutrient levels that can undergo or were shifted into turbid state. Two waterbodies showed hysteresis: at similar nutrient conditions one remained transparent with macrophytes, while other shifted in its turbid state with increased phytoplankton biomass, and reduced population of planktonic crustaceans. Rotifers contributed mainly to the metazooplankton diversity and abundance. The results suggested that total phosphorous and phytoplankton were the main drivers in turbid waterbodies, and biotic interactions governed structuring of zooplankton assemblage in transparent waterbodies. Habitats of submerged and floating-leaved macrophytes do not appear to a secure refuge for zooplankton against predation. On the other hand, sediment in the vegetated and non-vegetated littoral zone functioned as an effective shelter. According to our results, zooplankton underwent strong predation pressure by macroinvertebrates and small-sized fish in the littoral and by larger-sized fish in pelagial, with alteration related to ecosystem peculiarities. Based on an applied ecological network model, zooplankters were equally vulnerable to predation in both the pelagial and littoral zones, and these biotic interactions were main factors for zooplankton homogenous horizontal distribution. These results suggest that zooplankton organisms play important role in the matter cycling and resilience of the food webs to environmental alterations.
       
  • Ecological traits of water beetles in a karstic river from the Eastern
           Mediterranean region
    • Abstract: Publication date: Available online 18 June 2018Source: LimnologicaAuthor(s): Vlatka Mičetić Stanković, Manfred A. Jäch, Ivan Vučković, Aleksandar Popijač, Mladen Kerovec, Mladen KučinićABSTRACTThis study presents new insights into ecological traits of water beetles in lotic karst habitats of the Eastern Mediterranean. The aims of the study were to investigate population aspects and ecological traits of water beetles. Data were collected monthly during one year from a large perennial river showing current anthropogenic disturbance. Altogether 11 families, 23 genera and 31 species were identified. Elmidae were the most diverse and abundant family, and the genus Elmis predominated at all sampling sites. The distribution of water beetles along the river was influenced primarily by river bed morphology and beetle substrate preference. Water beetles were more abundant in bryophytes but more diverse in angiosperms. Ecological traits of water beetles along the watercourse were defined primarily by alkalinity and current velocity. Larval stages correlated with water depth and current velocity, while adult stage was related only to water depth. Our results support the potential of water beetles as indicators of water quality. This report provides the most detailed investigation so far of water beetles in the Eastern Mediterranean region, providing a basis for further detailed studies of water beetles and their ecology in freshwater habitats in southeastern Europe.

  • An experimental salt reduction in a lake with long-term hypersaline
           conditions does not increase zooplankton diversity but affects the grazing
           of Artemia persimilis on algae
    • Abstract: Publication date: May 2018Source: Limnologica, Volume 70Author(s): Alberto Pilati, Santiago A. Echaniz, Cristian G. Faguaga, Alicia M. Vignatti, Gabriela C. CabreraAbstractLakes from semiarid areas are generally temporary and saline, depending on the precipitation cycles. The negative effect of salinity on zooplankton richness when a lake dries up is well known, but much less is known about the outcome when a lake reduces its salinity because of rainfall events. Parque Luro Reserve is located in Argentina’s semiarid area, and it has a hypersaline shallow lake with extreme variations of depth and salinity. The objective of this research was to analyze the changes in zooplankton diversity when the lake’s salinity decreased. We also analyzed the hatching conditions of Artemia persimilis Piccinelli and Prosdocimi, 1968 and the grazing effect of this species on the algal community. We incubated lake sediments in microcosms with lake water for 45 days at salinities between 25 and 300 g L−1. The only species that hatched at salinities less than or equal to 100 g L−1 was A. persimilis. Hatching at higher salt concentrations, as observed in the field, would only occur if occasional rainfall produced a vertical stratification of salinity. The density and biomass of Artemia (dominated by post-naupliar stages) peaked at 50 g L−1. At salinities less than or equal to 100 g L−1, phytoplankton was not abundant, while periphyton was very abundant. The inverse relationship between A. persimilis and phytoplankton biomasses allowed us to corroborate a strong grazing effect of Artemia. The absence of other zooplankton species could be due to egg bank deterioration caused by the persistence of long-term hypersaline conditions. If other species appeared, they would by necessity have come from external sources.
       
  • DNA-based monitoring of the alien invasive North American crayfish
           Procambarus clarkii in Andean lakes (Ecuador)
    • Abstract: Publication date: May 2018Source: Limnologica, Volume 70Author(s): L. Riascos, A.N. Geerts, T. Oña, P. Goethals, J. Cevallos-Cevallos, W. Vanden Berghe, F.A.M. Volckaert, J. Bonilla, K. Muylaert, E. Velarde, P. Boets, Christine Van der heydenAbstractIn 2013 the red swamp crayfish (Procambarus clarkii) was introduced in Lake Yahuarcocha, a tropical, high altitude lake located in the Andes of northern Ecuador. Abundance of this alien invasive species has increased to such extent that it is disturbing the autochthonous aquatic ecosystem. Little is known about its distribution throughout Ecuador. Monitoring is therefore important to assess the current distribution and to control future spread. A molecular method based on environmental DNA (eDNA) was developed and used to assess the distribution of P. clarkii at 21 sites in Lake Yahuarcocha, and three sites each at Lake Caricocha and Lake San Pablo in the Ecuadorian highlands. The molecular detection of crayfish from water samples was compared to capture based distribution patterns obtained from traditional trapping. Results showed an eDNA detection accuracy of 86% in water samples, without false positives. The results indicate that this budget-friendly method is easy to use and can provide important information on the occurrence of alien invasive species in the tropics.
       
  • Contrasting patterns of macroinvertebrates inshore vs. offshore in a
           plateau eutrophic lake: Implications for lake management
    • Abstract: Publication date: May 2018Source: Limnologica, Volume 70Author(s): Shuran Cindy Wang, Xueqin Liu, Yong Liu, Hongzhu WangAbstractWorldwide there has been deterioration of lakeshore habitat and increasing eutrophication. These stresses have impacted littoral macroinvertebrate communities. However, bioassessment and rehabilitation have been largely carried out offshore, and the inshore macroinvertebrates have received less attention especially in shallow plateau lakes. In this study, we compared inshore and offshore macroinvertebrate communities in a shallow plateau lake, Lake Dianchi, China. The environmental parameters determining the distribution of macroinvertebrates were analyzed with partial redundancy analysis. Our results showed that macroinvertebrate communities differed significantly between inshore and offshore. Taxonomic richness was much higher inshore than offshore, due to higher habitat heterogeneity. By contrast, both density and biomass inshore were significantly lower than those of offshore. Generally, vegetation and substrate type were the key environmental parameters shaping macroinvertebrate communities. Eutrophication exerted great effect on offshore communities, while its impacts on inshore communities varied spatially. Shoreline degradation and seasonal eutrophication effects resulted in the limited density and biomass of inshore communities. Our results emphasized the significance of inshore habitats for macroinvertebrates in Lake Dianchi, and provided important implications for bioassessment and ecological rehabilitation in shallow lakes.
       
  • Comparison of two water sampling approaches for eDNA-based crayfish plague
           detection
    • Abstract: Publication date: May 2018Source: Limnologica, Volume 70Author(s): Claudia Wittwer, Carsten Nowak, David Allan Strand, Trude Vrålstad, Marco Thines, Stefan StollAbstractThe crayfish plague agent Aphanomyces astaci causes high fatality rates among European crayfish species and is transmitted by semi-immune North American crayfish species via zoospores. Recently environmental DNA (eDNA) techniques have been developed to detect the pathogen directly in water samples.To identify the optimal technique for concentrating spores out of water samples we tested two water filtration methods, namely depth filtration (DF) and dead-end ultrafiltration (DEUF), with subsequent qPCR-based detection of A. astaci spores from the water column in three river systems in Germany.Both eDNA methods were successful in recovering and detecting A. astaci spores from all three lotic water systems and the detection patterns were generally consistent across watercourse and season. Water turbidity negatively affected the A. astaci spore detection with both eDNA methods, with increasing pellet weights for the DEUF method and decreasing water volumes for the DF samples. Although filtering high-volume water samples with the DEUF method led to slightly higher detection rates of A. astaci and seemed to be more sensitive in A. astaci detection, its application is highly laborious and more costly. We therefore propose to use the DF method for large-scale screenings of A. astaci in running waters due to its fast, cost-effective and easy-to-apply sample processing and the very robust quantification results. We are confident that this method might be favored as well for eDNA studies of other organisms.
       
  • Factors influencing phosphorus regeneration by lake zooplankton—An
           experimental approach
    • Abstract: Publication date: May 2018Source: Limnologica, Volume 70Author(s): Jolanta Ejsmont-Karabin, Irina Feniova, Iwona Kostrzewska-Szlakowska, Marek Rzepecki, Varos G. Petrosyan, Andrew R. DzialowskiAbstractPhosphorus and nitrogen concentrations in the trophogenic zone in lakes are main factors determining the trophic state of lakes. The goal of this work was to assess the impacts of enrichment of lake water with nutrients, as well as the presence of large crustaceans, Dreissena polymorpha and fish on the process of phosphorus regeneration by zooplankton (rotifers and crustaceans) in experimental mesocosms. The experiment was carried out for 32 days and consisted of 12 treatments, each replicated in triplicate. The mesocosms were filled with 270 L of natural pelagic water from the eutrophic Lake Mikołajskie and kept on the shore of the lake. Fish did not to have any impact on phosphorus regeneration rates in any of the treatments, whereas the presence of bivalves increased phosphorus regeneration rates. Phosphorus regeneration rates did not affect phosphorus sedimentation in any of the treatments, but the loss of total phosphorus and its increased regeneration rates resulted in markedly decreasing turnover times of phosphorus in all treatments of the experiment. Nutrient enrichment mainly affected phosphorus regeneration by phytophagous and predatory crustaceans and had no impact on phosphorus regeneration by rotifers when large Cladocera were absent. Processes of phosphorus regeneration and uptake included in internal phosphorus cycling were under strong influence of biological factors, which acted quickly, through the changing trophic structure of zooplankton communities, which in turn changed the flow of phosphorus in trophic chains.
       
  • Diatom diversity at multiple scales in urban reservoirs in Southern Brazil
           reveals the likely role of trophic state
    • Abstract: Publication date: May 2018Source: Limnologica, Volume 70Author(s): Raquel C. Marra, Vanessa M. Algarte, Thelma A.V. Ludwig, André A. PadialAbstractDiatoms grow under very specific physical and chemical conditions, and eutrophication may cause community variation. We aimed to describe spatial and temporal variation in diatom community diversity in two urban reservoirs of different throphic status at different spatial scales. We collected samples of epiphytic diatoms from aquatic macrophytes from six sites in each reservoir in the metropolitan region of Curitiba, Southern Brazil, in fall and in spring. We assessed the variation in cell density and taxa richness (considering the lower taxonomic level possible) between the reservoirs and periods using t-tests, and the differences in community composition using PERMANOVA. Principal coordinates analysis (PCoA) was used to observe the change in floras between reservoirs and periods. We also partitioned gamma diversity into alpha and beta diversities using Additive Partitioning. In this case, variation components at different spatial scales were generated for each period. Beta diversities at different scales were also divided into turnover and nestedness components. We identified 132 infrageneric taxa in each reservoir. Spatial and temporal variation in species diversity and composition occurred in both reservoirs at different scales. Even so variation between reservoirs is a component that cannot be expected by a null model, indicating a possible role of eutrophication in community variation. Community variation at different scales was higher in the more eutrophic reservoir, in line with the positive relationship between beta diversity and productivity. Turnover was always the main component of beta diversity considering all spatial and temporal community variation. Nestedness occurred particularly in community variation among time periods at a same location, in line with studies suggesting community stability in urban reservoirs. Taken together, our results highlight the key role of nutrient availability in determining species composition, community variation within reservoirs, and community variation over time.
