The ISECI (or F index) has been the first fish index to be recommended by the Italian Ministry of the Environment to assess the rivers ecological status with regard to fish communities, in accordance with the Water Framework Directive 2000/60 EC. In addition to ISECI, other fish indices have been developed such as the Forneris Ichthyic Index (I.I.)...

In June 2020, a door-to-door household survey was conducted in Mvolo County, an onchocerciasis-endemic area in South Sudan. A total of 2357 households containing 15,699 individuals agreed to participate in the study. Of these, 5046 (32.1%, 95% CI: 31.4–32.9%) had skin itching and 445 (2.8%, 95% CI: 2.6–3.1%) were blind.

... A comparison with judgments assigned on expert basis in a blind approach was conducted to evaluate if the refinement improved the index performance in assessing the ecological status (Pagani et al., 2021). Three ichthyologists with long and proven experience in the regional freshwater context were involved in the study and for each of the 24 sites were asked to provide their estimation of the NISECI quality class after being provided with: ...
... The Table 5 SIMPER analysis results for each zone; "Av.Abund" is the average value of the species abundance in the zone; "Av.Sim." is the average for Bray-Curtis similarity values; "Contrib%" is the percentage contribution to similarity, cumulated in "Cum%" until the cut-off > 95 % is reached. NISECI, however, shows limits and difficulties in its application, mostly related to the definition of the reference conditions and their selection of expected species (Pagani et al., 2021;Rossi et al., 2021). Since the NISECI expresses a judgment on the observed fish community by measuring its deviation from an optimal theoretical condition, establishing appropriate reference conditions is fundamental (Macchio et al., 2017;Rossi et al., 2021). ...
Climate change is producing large impacts on rivers, amplifying hydrological extremes. Prolonged drought periods result in dramatic stress for river biota and associated processes due to low discharge, reducing the interactions between rivers and their lateral environments or leading to hydrological intermittency. New quantitative methods are needed, to correlate discharge with the available riverine habitats. In this work we have mapped the wet surface and paths of two stretches of the Taro and Trebbia Apennine rivers, analyzing satellite images from periods with contrasting discharge. The considered stretches are critical due to different human pressures (large water withdrawals for agriculture and industrial use) and are particularly vulnerable to further, climate‐driven discharge reductions. The produced images offer multiple possibilities to extract qualitative and quantitative information at the whole stretch scales, including habitat reduction along with decreasing discharge, threshold discharge limiting lateral interactions, or the evaluation of longitudinal river continuity. We discuss the limitation and the potentialities of the method and the maps produced in terms of possible application in the field of river geomorphology, ecology, the definition of ecological river flow, risk assessment, and river management.
