Seasonal changes in fish assemblages in the River Minho tidal freshwater wetlands, NW of the Iberian Peninsula p. 185

Seasonal abiotic parameters clearly influence ichthyofauna abundance, biomass and assemblages in River Minho tidal freshwater wetlands. Non-indigenous species heavily contributed for assemblages’ definition and their presence may become even more significant in a water temperature rise scenario.

Are metals in the muscle tissue of Mozambique tilapia a threat to human health? A case study of two impoundments in the Olifants River, Limpopo province, South Africa p. 201

Metal pollution is linked to potential human health risks in rural communities consuming fish from two contaminated reservoirs. Lead, antimony and chromium are potential health threats. The impact of acid mine drainage on fish and rural communities reliant on them are highlighted.

Small-scale variability of benthic macroinvertebrates distribution and its effects on biological monitoring p. 211

The precision of a macroinvertebrate multimetric index (MMI) was assessed by means of resampling methods.

MMI was highly affected by the heterogeneous distribution of taxa, especially with respect to abundance-based metrics.

The doubling of the sampling effort does not increase the precision of the MMI

Aquatic invertebrate assemblages in ponds from coastal Mediterranean wetlands p. 217

Aquatic invertebrate assemblages (micro-, macrozooplankton and macroinvertebrates) in coastal wetlands in Southeastern Spain are greatly influenced by human disturbances (input of nutrients, water level manipulation), fish (influencing especially cladocerans) and spatial and temporal changes in variables, as conductivity and macrophytes.

Initial growth phases of two bloom-forming cyanobacteria (Cylindrospermopsis raciborskii and Planktothrix agardhii) in monocultures and mixed cultures depending on light and nutrient conditions p. 231

- Initial fast-growing abilities of bloom-forming species assessed in mono vs mixed cultures.

- A low growth rate recorded in mixed cultures, suggesting possible competitive interactions under specific conditions.

- P. agardhii outcompete C. raciborski at low light intensity and high NO3- source; while C. raciborski outgrow at high NH4+ levels.

Seasonal evolution of the zooplankton community in two riverine wetlands of the Ticino River (Lombardy, Northern Italy) p. 241

We report the ecological situation of two riverine wetlands before the requalification process by investigating the way the zooplankton assemblages respond to anthropogenic pressure. The presence of any extent of anthropogenic impact immediately influences the equilibrium of such delicate ecosystems and prejudices their relevant ecological role.

The highly invasive Chinese mitten crab Eriocheir sinensis in the Tagus Estuary, Portugal: morphology of the specimens 20 years after the first captures p. 249

Eriocheir sinensis is an invasive species that spread in European waters as the result of human activity. During September 2013 E. sinensis population in the Tagus Estuary (Portugal) was sampled using fyke nets (n = 192). The captures from the Portuguese population were dominated by medium size individuals at the beginning of their reproducing cycle.

The role of tubificid worms (Limnodrilus hoffmeisteri) in sediment resuspension: a microcosm study p. 253

- Tubificid worms (imnodrilus hoffmeisteri) loosen sediment and increase the sediment water content and surface roughness.

- Tubificid worms increase suspended solids in the water column during light, moderate, and strong wind processes.

- Tubificid worms raise the proportion of fine particles in suspended solids.
