“…Accordingly, similar pattern in species diversity was observed. These results are in accordance with numerous previous studies (Godinho et al, 1997(Godinho et al, , 2000Carmona et al, 1999;Pires et al, 1999Pires et al, , 2004Mesquita and Coelho, 2002;Magalhães et al, 2002aMagalhães et al, , 2002bMagalhães et al, , 2007Clavero et al, 2004;Ferreira and Oliveira, 2004;Clavero and Garcia-Berthou, 2006;Mesquita et al, 2006;Ferreira et al, 2007aFerreira et al, , 2007b.

The use of river-types is of practical value, serving as groups for which assessment procedures can be developed and applied. An abiotic typology was set by the Portuguese Water Agency, mainly based on 6 major morphoclimatic regions. However, to be biologically meaningful, this typology should fit the distribution patterns of the biological quality elements communities proposed in Water Framework Directive under the lowest possible human pressure. This study aimed to identify and characterize fish-based geographical groups for continental Portugal and their environmental and geographical discriptors, using taxonomic and functional traits. Sampling took place between 2004 and 2006 during Spring. Fish fauna from 155 reference sites was analysed using a multivariate approach. Cluster Analysis on fish composition identified 10 fish-groups, expressing a clear correspondence to the river basin level, due to the restrict basin distribution of many species. Groups showed a wider aggregation in 4 regions with a larger geographical correspondence, statistically supported by Similarity Analysis, both on fish composition and mostly on fish metrics/guilds. Principal Components Analysis revealed major environmental drivers associated to fish-groups and fish-regions. Fish-groups were hierarchically grouped over major and local regions, expressing a large-scale response to a North-South environmental gradient defined by temperature, precipitation, mineralization and altitude, and a regional scale response mainly to drainage area and flow discharge. From North to South, fish-regions were related to the morphoclimatic regions. Results contributed to reduce redundance in abiotic river-types and set the final typology for Portuguese rivers, constituting a fundamental tool for planning and managing water resources.

“…Running waters belong to the most intensively used and altered ecosystems of the world (Saunders et al, 2002;Clavero et al, 2004;Levin et al, 2009). In Europe, about 80% of rivers are affected by water pollution, water removal for hydropower and irrigation, structural alterations and the impact of dams (Schinegger et al, 2011).…”

“…Such effects will be strong for the 45 species that are endemic to the Jinsha segment (see Table 1 in Supplementary Material). Dramatic changes of fish communities through extirpation of endemic species and increases in generalists were reported from other impounded rivers (Rahel 2002;Clavero et al 2004;Głowacki and Penczak 2013).…”

Construction of hydroelectric dams affect river ecosystems, fish diversity, and fisheries yields. However, there are no studies assessing the combined effects on fish caused by several adjacent dams and their reservoirs, as in a 'dam cascade'. This study predicts the potential effects that a cascade of ten dams currently under construction in the upper Yangtze River in China will have on local fishes, and uses such predictions to assess the effectiveness of possible fish conservation measures. We found that the dam cascade will have serious combined effects on fishes mainly due to impoundment, habitat fragmentation and blocking, flow regime modification, and hypolimnetic discharges. The impoundments will cause loss of critical habitats for 46 endemic species. The dams will fragment the populations of 134 species and will block migration routes for 35 potamodromous fishes.Corieus guichenoti will have a high risk of extinction due to the combined effects of impoundment and blocking. Modification of the flow regime will adversely affect the recruitment of 26 species that produce drifting eggs. The start of annual spawning for 13 fishes will be postponed by more than 1 month, and fish spawning and growth opportunities will be reduced due to low water temperatures associated with hypolimnetic discharges. Combined dam effects will further reduce the likelihood of successful recruitment of some endangered species, such as Acipenser dabryanus and Psephurus gladius. Three countermeasures hold promise to mitigate the nearterm effects of the dam cascade, including preservation and rehabilitation of critical habitat, restoration of a semi-natural flow regime, and stock enhancement that respects genetic integrity. These conclusions can guide the development of protection plans for fishes in the upper Yangtze River. The approach undertaken in this study-by which the known and likely effects of present and future dams were simultaneously Electronic supplementary material The online version of this article (doi:10.1007/s11160-015-9395-9) contains supplementary material, which is available to authorized users. 123Rev Fish Biol Fisheries (2015) 25:569-585 DOI 10.1007 considered in light of the biology of the specieshighlights the usefulness of ichthyology for fish conservation.

“…In its original distribution area the bleak occupies habitats with slow water (Brabrand, 1983). The attenuation of natural flow fluctuations in water bodies caused by dams has already been associated with the presence of other introduced species (Bernardo et al, 2003;Clavero et al, 2004).…”

Since its first record in a tributary of the Ebro basin in 1992, the bleak Alburnus alburnus has spread to almost the whole Iberian Peninsula. In this paper (based on electrofishing surveys in 598 localities), we provide information on the expansion of the bleak. We detail current distribution in the Ebro basin and the rivers of the Eastern Pyrenees and we report its presence in three other major Iberian drainages. Currently, the bleak is sympatric with 15 Iberian endemic species (58% of total Iberian endemic fish). The possible threats to the rich Iberian ichthyofauna caused by the presence of the bleak are discussed. The factors that promoted the extremely rapid expansion of this exotic cyprinid are examined, focusing on the role of reservoirs, which seem to favour its dispersal. Key words: cyprinids, distribution, fish introductions, Iberian Peninsula, invasive species. RESUMEN Expansión del alburno Alburnus alburnus (Linnaeus, 1758) (Actinopterygii, Cyprinidae) en la península Ibérica: el papel de los embalsesDesde su aparición en un afluente de la cuenca del Ebro en 1992, el alburno Alburnus alburnus se ha expandido en gran parte de la península Ibérica. El presente trabajo aporta nueva información sobre su expansión (basada en el muestreo de 598 localidades mediante pesca eléctrica). Se facilita información detallada sobre su actual distribución en la cuenca del Ebro y en cuencas al este de los Pirineos, así como nuevas citas de tres grandes cuencas hidrográficas. De acuerdo a su actual distribución en la península Ibérica, el alburno habita en simpatría con 15 especies endémicas (el 58% del total de
