      Abstract: 137Cs in abiotic components of ecosystems of the Crimean salt lakes: sources of inflow, features of distribution and eliminationMiroshnichenko, Oksana N.; Mirzoeva, Natalia Yu.; Sidorov, Ilya G.
      Fundamental and Applied Limnology, (2022), p. - AbstractA long-term study of the activity concentration of the artificial radionuclide 137Cs in the abiotic components of the ecosystems of the Crimean salt lakes during 2016–2020 is carried out. It was found that the contribution of the atmospheric inflow of the post-accident 137Cs into the Crimean salt lakes accounted for 88.5 %, while the water pathway of the inflow of the dissolved radionuclide accounted for 11.5 %. Activity of the dissolved form of 137Cs in lake water is within the range of 167.4 Bq·m–3 from below detectable, whereas in the bottom sediments it is within the range of 15.3 Bq·kg–1 from below detectable (data 2019). The 137Cs concentration levels in the bottom sediments of the salt lakes are 3 or more times lower than that in the bottom sediments of the Black Sea, while the distribution coefficients (Kds) are within values 101–104 (Bq·kg–1 Bq·kg–1). It is found that the salinity of water bodies is the main geochemical factor affecting distribution of 137Cs between abiotic components of the studied lakes. The 137Cs inventory in water and bottom sediments of the studied lakes are 6.5 GBq and 45.4 GBq, respectively. It determines the bottom sediments of the Crimean salt lakes as a sink of the post-accident artificial radionuclide 137Cs.

      Abstract: Taxa composition and ecological traits of filamentous diatoms in a regulated fragmented river, ChinaLi, Haiyan; Ge, Dayan; Yang, Wanling; Zeng, Yanyi; Liu, Qianfu; Gao, Yuan; Mai, Yongzhan; Wang, Chao
      Fundamental and Applied Limnology, (2022), p. - AbstractFilamentous diatoms generally form filamentous or chain like groups by the thorn or protrusion structure between adjacent cells, which are important components of phytoplankton communities in large river ecosystems. In order to explore the indicating functions of filamentous diatoms in response to cascade dam constructions in aquatic ecosystems, we investigated the 13 cascade dams along the main channel of the East River (China) during November 2018 (dry period) and July 2019 (wet period). A total of 18 filamentous diatoms (including variants) were identified, including 14 species of Aulacoseira and 4 species of Melosira, among which Aulacoseira granulata was predominant. The biomass of filamentous diatoms could be a good bioindicator for seasonal and spatial variations of water environments, since it appeared apparently higher in high water retention time (WRT) conditions (dry seasons or downstream). As for each cascade, the maximum or minimum biomass often appeared at stations closest to the dam. The filament length of Aulacoseira was longer than that of Melosira, which was mainly caused by morphological and structural differences. The filament length of A. granulata could be a good bioindicator of seasonal variations, since it was larger in dry seasons than that in wet seasons. The filament length of M. varians could be a good bioindicator of seasonal and spatial variations of water environments, since it appeared apparently more often in high WRT conditions (dry seasons or downstream). Moreover, both biomass and morphological traits of filamentous diatoms were mainly impacted by physical factors, which implied that the nutrient conditions of this fragmented aquatic ecosystem is beyond the demands of algal growth. In conclusion, the abundance and ecological traits of filamentous diatoms are suitable for identifying the spatial and seasonal characteristics of aquatic environments greatly affected by cascade dams.

      Abstract: Spatial versus temporal heterogeneity in abundance of fishes in north-temperate lakesRypel, Andrew L.
      Fundamental and Applied Limnology, (2021), p. 173 - 185AbstractProbing relationships between spatial and temporal heterogeneity is a central pursuit in limnology and ecology, but until recently, data availability has constrained empirical tests of these patterns. In this study, I quantified spatial and temporal heterogeneity in fish species abundances within a landscape of north-temperate lakes and resolved an empirical relationship between heterogeneity dimensions. Across 18 species, there was an asymptotic relationship between spatial and temporal heterogeneity; thus spatial heterogeneity predicted temporal heterogeneity, but only at low heterogeneity levels. Some species expressed low levels of temporal-to-spatial heterogeneity while others, remarkably, had temporal heterogeneity ≥ 100 % spatial heterogeneity. Relationships between spatial and temporal heterogeneity are likely useful for conservation and management. For example, species with low temporal:spatial heterogeneity ratios might benefit from landscape-scale management efforts (e.g., watershed management, hydrologic connectance, public land acquisitions). In contrast, species with high temporal:spatial heterogeneity ratios might be more successfully managed locally (e.g., via biomanipulation, hydrologic management, habitat restoration).

      Abstract: Interactions between Hygrophila polysperma and Ludwigia repens grown in saturated soil and shallow water under ex situ conditionsHutchinson, Jeffrey T.
      Fundamental and Applied Limnology, (2021), p. 187 - 198AbstractLudwigia repens, a native, and Hygrophila polysperma, an invasive, are morphologically similar amphibious plants occurring in spring runs of Central Texas and other aquatic habitat in Florida. Hygrophila polysperma is a dominant species in static and slow flowing waters < 0.05 m s–2 while L repens occurs sporadically in similar conditions in the San Marcos River. Planting efforts to restore L repens in flowing water> 20 cm were unsuccessful where H polysperma was manually removed. In this interaction study, Ludwigia repens and Hygrophila polysperma were subjected to different planting ratios. L repens exhibited greater growth in shallow static water at a depth of 15 cm when grown in equal or higher ratios compared to H polysperma. No difference in growth rates was detected between the species grown in saturated soils. Photosynthetic rates were greater for L repens in saturated soils and shallow water indicating this species is more tolerant of sunlight than H polysperma Hygrophila polysperma allocated greater biomass to its roots indicating this species may be more adaptable to scouring from floods and extended droughts by greater regrowth from roots. Moreover, Hygrophila polysperma exhibited lower light saturation rates indicating this species is more tolerant of lower light levels. The results of this study indicate that L repens will be competitive in restoration efforts if planted in shallow water with no or minimal flows in areas where H polysperma has been removed.

      Abstract: Local spatial distribution of stream macroalgae – does gastropod activity matters?Tonetto, Aurélio Fajar; Branco, Ciro Cesar Zanini
      Fundamental and Applied Limnology, (2021), p. 199 - 209AbstractThe effects of gastropod Biomphalaria sp. on the benthic algae community (micro and macroalgae) were experimentally studied in an unshaded artificial stream. Using artificial substrates, two treatments were tested: with herbivores and without herbivores. The substrates remained submerged for 50 days, and the environmental and biological variables (algal abundance and richness) were obtained on days 7, 15, 30, 40 and 50 after the experiment has been installed. Repeated measure analyses of variance were applied to verify possible differences of chlorophyll-a content, species richness, microalgal density and macroalgal density and percent cover between treatments at each date. Results showed that herbivory pressure reduces significantly all measured biotic variables except algal richness. Higher presence of macroalgae was related to a higher presence of microalgae in the substrates, indicating a potential relationship between these components. Thus, it seems that herbivore activity over microalgal biomass may have an indirect and negative effect on macroalgae, so that a reduction in microalgal density by grazing may have led to a corresponding decrease in abundance of macroalgae. Thus, the results suggest that the establishment and development of macroalgae in lotic environments can be regulated by a top-down cascade effect, in which the action of herbivores, herein the scraper Biomphalaria sp., on microalgae indirectly impacts the abundance of macroalgae.

      Abstract: Stability of pH, conductivity and alkalinity in dilute clear water samples exposed to various environmental conditionsEnge, Espen; van der Hoeven, Henrik; Kommedal, Roald
      Fundamental and Applied Limnology, (2021), p. 211 - 219AbstractA total of 260 bottled water samples from 10 pristine oligotrophic mountain lakes and rivers in southwestern Norway, sampled in 2012, 2013 and 2017, were exposed to a number of environmental conditions, disregarding established guidelines for handling and storing. Despite harsh treatment of the samples, only limited effects on pH (–0.02 ± 0.05, n = 260) and conductivity (+0.1 ± 0.3 µS cm–1, n = 260) and no effects on alkalinity (0 ± 2 µM, n = 260) were detected. Negligible effects of leaving a headspace (11 %) in the bottles were observed. However, uncapping of the bottles had an immediate deteriorating effect. We suggest that the chemistry of oligotrophic samples with low content of organic matter (“color”) are stable well within analytical uncertainties for these three parameters for at least two months, fairly independent of storage conditions and handling, provided that the bottles are stored capped and have not been opened.

      Abstract: Enhancing the aquatic conditions for the fresh water bivalves of River Nile, Egypt by functionalized carbon nanotube filtersElsehly, Emad M.; Ghonim, Aml Z.
      Fundamental and Applied Limnology, (2021), p. 221 - 230AbstractFreshwater bivalves play a vital role in aquatic ecosystems. The pollution of water supplies with a wide variety of contaminants and bacterial diseases affect bivalve’s differently according to their life stage. In the current study functionalized multi-walled carbon nanotube (F-MWCNT) filters were employed to enhance the aquatic conditions for the freshwater bivalve, Mutela singularis (M. singularis). The water samples, contaminated with the heavy metals (Cd, Co, Cr, Cu, Fe, Ni, Pb, and Zn), and bivalves were collected from Abu Hummus, River Nile, Egypt. The biochemical composition of M. singularis before and after using F-MWCNT filters was investigated. A number of Vibrio and Staphylococcus species was considered as important pathogens that were eliminated by F-MWNTs. Our findings revealed enhanced removal at high pH for the metals Co, Cu, Fe, Pb, Ni and Zn, however the exclusion at low pH for Cd, and Cr. F-MWCNTs-based filters showed 99.8 % removal efficiency of copper for 5 µg L–1 concentration at pH = 10. M. singularis samples in the purified conditions showed high quality of structure followed by a significant increase in the amount of carbohydrate, lipid and protein. The filtration mechanisms as a function of the pH value were discussed. Our study makes a significant contribution not only to the water treatment but also for the potential feeding fields.

      Abstract: Changes in the structure and composition of freshwater oligochaete fauna in response to different types of tropical springs, BrazilRodrigues, Luciana Falci Theza; Guimarães, Luiza Pedrosa; Rocha, Cézar Henrique Barra; Alves, Roberto da Gama
      Fundamental and Applied Limnology, (2021), p. 231 - 242AbstractThe aquatic oligochaete fauna from 71 tropical springs was studied to investigate the role of spring typology and environmental variables in the structuring and composition of assemblages. Multivariate analyses showed that, in general, limnocrene and rheocrene springs ordered themselves closer to each other than to helocrene springs, suggesting higher environmental and faunistic similarities between them. Helocrene springs were shallower, rich in total phosphorus and nitrogen, with a predominance of finer fractions of substrate, and occurred in lower altitude areas. We have found differences in abundance, richness, and composition of oligochaetes in springs of the helocrene type, but not between the other crenal types. Changes in the structure and composition of assemblages may be related to the changes in substrate composition (granulometry and nutrients). The most abundant family was Enchytraeidae, and the Naididae family was the most diverse. We concluded that the abiotic conditions of different types of springs influence the way oligochaete assemblages are structured. This study is the first in Brazilian springs and our results contribute to the understanding of the relationship between the oligofauna and the environmental variables in tropical spring habitats. In addition, it provides information on the neotropical biodiversity of oligochaetes.

      Abstract: Summer flower pulses: Catkin litter processing in headwater streamsGarthwaite, Iris J.; Froedin-Morgensen, Angie; Hartford, Sorrel H.; Claeson, Shannon M.; Ramstack Hobbs, Joy M.; LeRoy, Carri J.
      Fundamental and Applied Limnology, (2021), p. 243 - 254AbstractThe influences of inter- and intraspecific variation in leaf litter quality on aquatic food webs are well understood. However, the timing and type of organic matter inputs also varies within a species based on plant phenophase, including litterfall and flowering, which may influence instream communities and ecosystem processes including decomposition. We investigated how leaf and flower litters of a willow shrub species (Salix sitchensis) influenced decomposition and aquatic invertebrate colonization in a headwater stream. We collected abscised willow catkins and leaves from female plants, analyzed their initial chemistry, constructed litterbags, and incubated them at our stream site for five weeks. A subset of litterbags of each litter type was retrieved at 7, 22, and 37 days and analyzed for litter decomposition and invertebrate colonization. We found significant differences between catkins and leaves. Catkins had lower initial condensed tannin concentrations and higher invertebrate colonization compared to leaves. Initial leaching losses were faster for leaves, but overall decomposition rates were comparable. Catkin structural complexity supported higher invertebrate abundance and diversity as well as altered community composition, indicating their unique contribution to stream ecosystems. Although the ratio of reproductive to leaf inputs is low, we argue that the sequential availability of these two litter types may provide complementary energy inputs to consumers in headwater stream ecosystems dependent on organic matter.
