An overview of the effects of urbanization on the quantity and quality of groundwater in South Asian megacities
Limnology - Tập 14 - Trang 135-145 - 2012
One of the challenges facing megacities in South Asian developing countries in their attempts to realize so-called urban rejuvenation is groundwater conditioned by canal seepage and immense sewage loads. To understand the connection between groundwater pollutants and urbanization, numerous studies were reviewed, and data obtained from a variety of national and international organizations were anal...... hiện toàn bộ
Assessment of the occurrence and abundance of an exotic zooplankton species (Kellicottia bostiniensis) across a neotropical wetland over 12 years
Limnology - Tập 24 - Trang 137-149 - 2023
Understanding how the occurrence and abundance of invasive species vary over time and the environmental factors that cause such variation is important for managing and controlling invasive species. To date, studies with this perspective remain scarce in the Neotropics. We used a database describing 12 years of the occurrence of an invasive rotifer (Kellicottia bostoniensis) in a large neotropical...... hiện toàn bộ
Detection of geosmin from Coelosphaerium kuetzingianum separated by a step density gradient medium from suspended materials in water in Lake Shinji, Japan
Limnology - Tập 12 - Trang 253-260 - 2011
To identify the geosmin-producing organisms in Lake Shinji, Japan, we conducted preliminary chemical and biological investigations from April to July 2008, during which odor occurrence was observed. Geosmin was mainly detected in the suspended substance (SS) of lake water, and its concentration corresponded to the cell numbers of Coelosphaerium kuetzingianum (Cyanophyceae) and Monoraphidium contor...... hiện toàn bộ
Pathways of macroinvertebrate invasions in the Ob River basin (West Siberia)
Limnology - Tập 18 - Trang 243-249 - 2017
Water bodies of West Siberia mainly belong to the Ob River basin, which is not connected to other basins by shipping canals. The relative isolation of the basin predetermined the major role of industrial fisheries and aquarium trade in alien invertebrate transfer into the basin reservoirs. About 60% of the alien species were introduced into water bodies of West Siberia through industrial fisheries...... hiện toàn bộ
Direct and indirect impacts of predation by fish on the zooplankton community: an experimental analysis using tanks
Limnology - Tập 5 - Trang 121-124 - 2004
The impact of Pseudorasbora parva, a common zooplanktivorous fish species in Japan, on a zooplankton community was analyzed in experimental tanks, half of which were stocked with the fish. Different zooplankton species showed different responses to the introduction of the fish. In the presence of the fish, the populations of the large cladoceran Ceriodaphnia and the predatory copepod Mesocyclops w...... hiện toàn bộ
Simplification and replacement of diatom functional traits from a subtropical floodplain lakes paleolimnological records
Limnology - Tập 23 - Trang 153-163 - 2021
An effective way to access processes of ecological communities and ecosystems is the use of functional traits; therefore, the use of the functional characteristics of diatoms in paleolimnological works has been growing. In this study, the variations in the abundance of functional traits of sedimentary diatoms were evaluated in two lakes (Garças Lake and Patos Lake), from a subtropical floodplain, ...... hiện toàn bộ
Changes of fish assemblages after construction of an estuary barrage in the lower Nakdong River, South Korea
Limnology - Tập 17 - Trang 183-197 - 2016
In the Nakdong River, an estuary barrage was constructed in 1987, and it divided the freshwater and the seawater, resulting in a change in the ecosystem. To estimate the impact of barrage construction on fish assemblages, we evaluated 20 years of monitoring data before and after the construction of the estuary barrage, and evaluated the role of fishways. The barrage construction generated entire c...... hiện toàn bộ
Influence of climate seasonality on the effectiveness of the use of aquatic macroinvertebrates in urban impact evaluation in central Amazonia
Limnology - - 2021
Natural fluctuations in ecosystems, such as those associated with climate, are a fundamental factor structuring macroinvertebrate assemblages. Given that macroinvertebrates are widely used in biomonitoring of aquatic systems, it is necessary assess the potential effects of seasonality on this group to avoid confusing its effects with the effects of anthropogenic impacts. In the present study, the ...... hiện toàn bộ
