Temperature preference of juvenile (age 1+) Arctic charr (Salvelinus alpinus L.) originating from four arctic and sub-arctic populations (Svalbard and mainland northern Norway), representing a range of habitats with different temperature conditions, was studied by use of a shuttle-box system which allowed individual fish to control their environmental temperature. Based on the assumption that adap...... hiện toàn bộ
The influence of cooling water discharge upon fishHydrobiological Bulletin - Tập 13 - Trang 94-95 - 1979
J. Willemsen
Research on this influence was mainly carried out near the Flevo power station (846 MW) at the SW-border of Lake IJssel (120.000 ha). Temperature increase during the summer amounts to 6–7°C, during the winter up to 14°C. Fish were extremely abundant in the discharge area, the total fish population was at least 200 times as dense as elsewhere in the lake. The extent to which the various species con...... hiện toàn bộ

What are the main environmental predictors of differences in the community structure of periphytic desmids in a semi-arid floodplain lake?Hydrobiological Bulletin - Tập 56 - Trang 1037-1053 - 2022
Maria Aparecida dos Santos, Carla Ferragut, Nadson Ressyé Simões, Daniela Mariano Lopes da Silva, Carlos Wallace do Nascimento Moura
The desmids constitute a highly diverse group with potential as a bioindicator of the conservation status of freshwater environments. We evaluated the changes in the desmid community on macrophytes with different structural complexities within mixed stands in a floodplain shallow lake in the Brazilian semi-arid region. Our main question was whether the environmental variables that best predict des...... hiện toàn bộ
Trophic ecology of benthic fish assemblages in a lowland river in the Brazilian AmazonHydrobiological Bulletin - Tập 53 - Trang 707-718 - 2019
Cleber Duarte, Anne E. Magurran, Jansen Zuanon, Cláudia P. Deus
Studies on the trophic ecology of fish have revealed considerable alimentary plasticity for the majority of ichthyofauna in tropical rivers. This leads to the prediction that diet reflects the availability of food in the environment, namely seasonal variation in the abundance and type of food resources. To examine this, we assess: (1) seasonal variation in the diet and trophic structure of assembl...... hiện toàn bộ
A mathematical model for the vertical distribution of chlorophyllA in estuarine intertidal sedimentsHydrobiological Bulletin - Tập 29 - Trang 315-321 - 1995
Vanda Brotas, João Serôdio
Coastal and estuarine intertidal sediments are commonly colonized by dense populations of microphytobenthos. Due to wind and tides, important fractions of microphytobenthic populations may be buried. A mathematical model describing the depth variation of chlorophyll a in intertidal sediments was developed and experimentally tested. The model assumed first-order chlorophylla degradation and a const...... hiện toàn bộ
A one-dimensional model of vertical stratification of Lake Shira focussed on winter conditions and ice coverHydrobiological Bulletin - Tập 44 - Trang 571-584 - 2010

In meromictic lakes such as Lake Shira, horizontal inhomogeneity is small in comparison with vertical gradients. To determine the vertical distribution of temperature, salinity, and density of water in a deep zone of a Lake Shira, or other saline lakes, a one-dimensional (in vertical direction) mathematical model is presented. A special feature of this model is that it takes into account the proce...... hiện toàn bộ
