International Review of Hydrobiology (INT REV HYDROBIOL)

Journal description

International Review of Hydrobiology - Homepage Throughout the decades the development of water ecology has been reflected in this journal: the analysis and assessment of biological structures in water in their interconnection with the internal and external cycle of materials. Today the articles reflect the journal's title: Hydrobiology - the science of life processes in water. It is international forming the basis for relevant decisions in politics and society since mankind is dependent on water in so many ways. An international team of scientists guarantees the international character and comprehensive coverage of this journal.

    ABSTRACT: Springs are relevant environments from an ecological point of view. The microhabitat-mosaic structure of these ecotones often harbors high biodiversity. Due to the temperature stability of permanent springs and to the persistence over geological time scales of their aquifers, these environments may act as refugia and as potential speciation sites for aquatic fauna. In this study, we review the current knowledge on the diversity and distribution of ostracods associated with ambient springs in the Western Palearctic area, and on the ecological factors that have been reported to affect their occurrence. Literature mining revealed 37 papers, allowing to gather information on 92 ostracod taxa belonging to 31 genera, found in 612 springs out of a total of 743. More detailed information available from 20 studies carried out in the Central-Eastern Alps and Northern Apennines allowed us to conduct a focus study on a more restricted geographic area. Several species have very low frequency, occurring in just one or two springs. Rare or endemic species were frequent, whilst only one non-native species (Chlamydoteca incisa) was found. Species richness varied from 1 to 9, and it was greater in pool springs than in flowing springs and seepages. Correspondence analysis on the presence-absence data unveiled biogeographical patterns in spring ostracod community composition. The variation in community composition was partly organised along altitudinal, latitudinal, water-temperature, and conductivity gradients, and spring typologies affected assemblage structure as well. Springs are important areas for biodiversity conservation at the continental and regional scale. Nevertheless, relatively few investigations have dealt with the human impacts on springs and their biota, and conservation guidelines are largely missing.

    ABSTRACT: Two morphologically similar pre-dams (Hassel and Rappbode pre-dams, Harz Mountains, Germany) of a large reservoir with different land use in their catchments were compared with respect to their physical, chemical, and biological properties in order to test if differences can be attributed to the different land use. In addition, local geology, soil types, and topography were evaluated in detail to distinguish its influence from that of present-day land use. Despite a remarkable similarity in physical variables and stratification, the annual development of hydrochemistry and biology differed between Rappbode and Hassel pre-dam. While the Hassel pre-dam received much higher nitrogen and phosphorus inputs from the catchment, the Rappbode pre-dam received more dissolved organic carbon. The quality of dissolved organic carbon also differed between the two catchments, indicating different sources. The higher residence time of Hassel pre-dam amplified the effects of these inputs on the trophic state of both pre-dams. The phytoplankton communities in summer were dominated by diatoms in the Rappbode pre-dam and by cyanobacteria in the Hassel pre-dam. In conclusion, land use appeared to be an important driver for the observed lake characteristics. However, it was itself strongly related to soil types and topography, which on the other hand influences the residence time of water within the catchments.

    ABSTRACT: We investigated the influence of light on phototactic behavior and reproduction in two species of rotifer from the Brachionus plicatilis species complex (B. plicatilis sensu stricto (s. s.) and Brachionus manjavacas). This was done to understand how light effects these species so that we might use this knowledge to establish a more efficient aquaculture protocol. We used four different light wavelengths (white, with peaks at 460 and 570 nm; blue at 470 nm; green at 525 nm; and red at 660 nm) and four intensities (i.e., 0.5–30.0 W/m2). Using micro-spectrophotometry we determined that eyespots of these two Brachionus species absorbed blue and green light 5.5 times more than red light. B. plicatilis s. s. showed positive phototaxis under white, blue, and green light at lower light intensities, but no phototaxis under red light at all intensities (0.5, 6.2, 15.0, and 30.0 W/m2). Similar patterns of phototaxis were observed in B. manjavacas and did not differ among mictic, amictic females, and male rotifers. Population growth rate of B. plicatilis s. s. under dark condition was 1.1–1.2 times higher than that under white light condition. No significant differences were observed in population growth rate at 3.8 and 6.2 W/m2 at all light wavelengths. On the other hand, population growth rates at 0.5 and 1.6 W/m2 were the lowest under blue light. According to these results, both wavelength and intensity of light affect the population growth of rotifers, which in turn may be influenced by the rotifers' wavelength-dependent phototaxis.

    ABSTRACT: We investigated the effects of fortifying a diet of Chlorella vulgaris with Selenium (Se) on sexual and asexual reproduction of rotifers in the Brachionus plicatilis species complex: i.e. two strains of B. plicatilis sensu stricto and one of Brachionus rotundiformis. These rotifers were cultured for 8–10 days on one of three different diets that were adjusted to provide the same dry weight of food: non-fortified Chlorella, Se-fortified Chlorella, and Nannochloropsis oculata. B. plicatilis (Makishima strain), which is obligatorily asexual, showed no difference in population growth rate among the three different diets (r = 0.55–0.61). On the other hand, B. plicatilis (NH17L strain), which reproduces by cyclical parthenogenesis, showed higher population growth (r = 0.25) and also higher rates of fertilization (35.9%) and absolute resting egg production (2803.9 eggs/g food) with the Se-fortified Chlorella diet than with other foods. Although B. rotundiformis (Kochi strain), which also exhibits cyclical parthenogenesis, showed no differences in population growth among the three different diets (r = 0.42–0.48), sexual reproduction parameters were different depending on the feeding regime. The highest mixis (26.2%), fertilization (72.6%), and resting egg production (3489.9 eggs/g food) were observed with the Se-fortified Chlorella diet. We posit that the effect of Se-fortified diet was greater on the resting egg production by enhancing male fertility than on population growth.
