An eco-hydrological assessment method for temporary rivers. The Celone and Salsola rivers case study (SE, Italy) p. 1

The research deals with three different aspects which are relevant for supporting the assessment of the Ecological Status in temporary rivers: river type classifications, analysis of the different sets of mesohabitats which can occur in a reach in a certain period, and Hydrological Status (divergence of actual regime from its natural condition).

Influence of landscape properties on stream water quality in agricultural catchments in Southeastern Brazil p. 11

In southeast Brazil, sugarcane seems to be increasing nitrate in streams and pasture increasing suspended sediments and turbidity. Forest fragmented and restricted to the area close to water bodies are not capable to contain these impacts. These results show the importance of discuss the politic of conservation of riparian forests.

Estimating sediment and particulate organic nitrogen and particulate organic phosphorous yields from a volcanic watershed characterized by forest and agriculture using SWAT model p. 23

SWAT model was applied for estimating sediment yield in a volcanic watershed.

Relationships between PON, POP and sediment concentrations were identified.

Annual PON and POP yields were estimated.

Critical source area of land surface erosion was identified with SWAT model.

A simplified algorithm for calculating benthic nutrient fluxes in river systems p. 37

Benthic processes play a major role in aquatic ecosystems.

Detailed models of these processes exist but are costly in terms of calculation time.

A simplified surrogate algorithm is derived to simplify benthic flux calculation in river system models.

Indirect effect of environmental factors on interactions between microbial and classical food webs in freshwater ecosystems p. 49

While the influence of environmental factors on the abundance of aquatic animals is fairly well documented, less has been done to research their influence on food web interactions. Among a plenty of environmental factors measured, total solids, transparency and temperature were most closely related to the variation in trophic communities. The analyses of food web interactions under low and high levels of those factors revealed that they differently influenced strengths among food web components.

Evaluation of hydrology, suspended sediment and Nickel loads in a small watershed in Basque Country (Northern Spain) using eco-hydrological SWAT model p. 59

Nickel concentration was computed from simulated SSS by SWAT.

Temporal variability of Nickel load is related with suspended sediments.

In terms of temporal dynamics in the sediments and Nickel transport, Oka catchment showed a high temporal variability.

The mean specific of sediment load was 33 t/km−2/y−1and Nickel load was 1.63 kg/km−2/y−1.

New records of Chironomidae (Diptera) of Tuvalu p. 71

This paper presents the first report on the Tuvaluan Chironomidae. It may add some knowledge on Oceanian freshwater fauna. Four species belonging to three genera are recognised. Compterosmittia longipalpis, Pseudosmittia tuvaluensis and Pseudosmittia amplexivirga are described as new species.

Food, substrate or both? Decomposition of reed leaves (Phragmites australis) by aquatic macroinvertebrates in a large shallow lake (Lake Balaton, Hungary) p. 79

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
