Profundal benthic invertebrate communities in boreal lakes vary with climate fluctuationSchweizerische Zeitschrift für Hydrologie - Tập 77 - Trang 261-269 - 2014
Jussi Jyväsjärvi, Heikki Hämäläinen
Despite increasing evidence that climate change affects aquatic ecosystems, influences on lake benthic communities are still poorly known. We studied the effects of short-term climatic fluctuation on profundal benthic invertebrates using at least six annual samples (over 6–17 years) from 38 Finnish lake basins. Faunal abundance, species diversity and species composition were related to annual wint...... hiện toàn bộ
Aquatic ecotoxicologySchweizerische Zeitschrift für Hydrologie - Tập 46 - Trang 100-108 - 1984
Erik R. Christensen
Information about the toxicity of heavy metals and organics to aquatic organisms can be obtained from bioassays. These are classified according to the type of response obtained: quantal or continuous, and according to whether individual organisms originate from a single clone or have a tolerance distribution. Basic features of the probit, logit, and Weibull dose-response models for one toxic subst...... hiện toàn bộ
Assessing water stress in Mediterranean lotic systems: insights from an artificially intermittent river in GreeceSchweizerische Zeitschrift für Hydrologie - Tập 73 - Trang 581-597 - 2011

Water stress in Mediterranean countries is the result of both variable and changing climatic conditions and widespread anthropogenic pressures. Evrotas, an intermittent river located in Southern Greece, was used as a case study to assess the impacts of water stress on Mediterranean lotic ecosystems. Based on hydrological analyses, it was revealed that during prolonged drought years, such as the su...... hiện toàn bộ
The role of seedbanks and hyporheic refuges in supporting benthic invertebrate community resistance and resilience to dry phasesSchweizerische Zeitschrift für Hydrologie - Tập 86 - Trang 1-13 - 2023
Aida Viza, Rebeca Arias-Real, Margarita Menéndez, Isabel Muñoz
In intermittent streams, aquatic organisms use various strategies to face dry phases, but the relative contribution of these strategies to persist during dry phase remains unclear. Here, we investigated the in situ persistence of benthic invertebrates in the saturated hyporheic sediments and the “invertebrate seedbank” that persists in dry sediments across six Mediterranean intermittent streams.

Controls on the export of C, N, P and Fe from undisturbed boreal catchments, FinlandSchweizerische Zeitschrift für Hydrologie - Tập 68 Số 4 - Trang 453-468 - 2006
Kortelainen, Pirkko, Mattsson, Tuija, Finér, Leena, Ahtiainen, Marketta, Saukkonen, Sari, Sallantaus, Tapani
Associations between catchment characteristics (altitude, slope, proportion of peatland, site fertility, total stem volume, and its distribution among the main tree species), climatic drivers (temperature sum, latitude, precipitation and runoff) and atmospheric deposition and concentrations and export of C, N, P and Fe in 21 unmanaged boreal catchments (0.07 to 14 km2) were examined in data s...... hiện toàn bộ
Sprungschichtneigung im Zürichsee durch SturmSchweizerische Zeitschrift für Hydrologie - Tập 11 - Trang 527-545 - 1949
E. A. Thomas
During the thermocline tilt, observed in November 1947 in Lake Zürich, a difference in level of 16 m was found between the highest point (Quaibrücke) and the equivalent lowest point (middle of the Lake Stäfa-Ufenau). The “fulcrum” line of this tilt was found somewhat N. of the deepest point and probably ran somewhat diagonally across the lake (e. g. Herrliberg-Rüschlikon) as a result of the angle ...... hiện toàn bộ
