Factors affecting the distribution of fish during receding flood in lower Irtysh: effects of water level and diurnal cycle p. 89

Juvenile Cyprinidae represented more than 80% of all fish in the lower Irtysh. Illumination level had the strongest effect on fish density, fish density was significantly higher at night. Effects of local ecological heterogeneity and the water level change were relatively weak. Downstream and upstream migrations of fish in a floodplain stream were documented.

Distributional patterns of non-marine Ostracoda (Crustacea) in Adiyaman Province (Turkey) p. 101

This study numerically contributes to the Turkish non-marine ostracod fauna. Besides, it offers important information about ecology of ostracod species. Indeed, It provides information to understand the distributional pattrens of this bioindicator organisms in freshwaters.

Is the diet of a typical shredder related to the physical habitat of headwater streams in the Brazilian Cerrado? p. 115

Examined & classified gut contents of the shredder, Phylloicus, from 2 Brazil basins

FPOM dominated in both basins & differed with instar, instream & riparian habitat variables, & basin

Phylloicus has dietary flexibility; additional study is needed for accurate guild classification

Eucypris fontana (Graf, 1931) (Crustacea, Ostracoda) in permanent environments of Patagonia Argentina: a geometric morphometric approach p. 125

Geometric morphometric techniques were used to describe the morphological variations of Eucypris fontana (Crustacea, Ostracoda) in different non marine environments of Patagonia. Our results show a relationship between the valves morphology and the physical-chemical characteristics of the host waters.

Diversity of algae in a thallium and other heavy metals-polluted environment p. 139

Algal diversity in a thallium and other heavy metals-polluted environment was examined.

Some observed algae showed broader ecological spectra.

High diversity of Phacus sp. was noted for the first time from thallium-polluted waters.

Emergence patterns in tropical insects: the role of water discharge frequency in an Andean Stream p. 147

Temporal patterns of aquatic insect emergence were studied in a 3rd order Andean stream

Aquatic insect orders showed different responses to discharge patterns

A high percentage of emergences occurred within two discharge categories: <0.352 and 0.352–0.579 m3.s−1.

ARIMA models were applied to analyze the time series data.

This study provides relevant information about the ecology of aquatic insects in Andean freshwaters.

Trichopteran fauna of a hydrographic basin with a complex geological history (Umbria – Central Italy) p. 157

The inventory of Trichoptera in Topino river basin shows numerous species (83) in lotic and lentic waters, especially in rheocrenous and limnocrenous springs. 21 species are endemic to Italian fauna. The variety of habitats is linked to the tectonic phenomena which affected the basin from later Miocene to early Pleistocene.

Influence of temperature on surface sediment disturbance by freshwater fish: a microcosm experiment p. 179

We experimentally assessed the influence of two contrasted temperatures on surface sediment disturbance (SSD) by three freshwater fish species

SSD was 2-3 times higher at 20°C than at 10°C for the three species

The stone loach had a higher SSD activity than the two cyprinid species

Our results suggest that SSD by fish could increase in future warmed conditions.
