“…Previous works conducted at the same study site concluded that this part of the systems displays a moderate organic pollution evidenced by the biochemical oxygen demand (2-5 mg.l -1 ), although extreme values of ammonia (500 to 3000 ug.l -1 ) and nitrates (220-800 ug.l -) were also recognized (MiseRendino, 2001;MiseRendino & BRand, 2009). The toxic and lethal effect of some substances as for example ammonia on invertebrates has been widely reported (BeketoV, 2004;langfoRd et al, 2009). Our results suggest that species of Hirudinea recorded at this site were capable to support moderate to strong pollution which is in line with found for other species of Hirudinea including Glossiphoniidae (nelson et al, 2000;langfoRd et al, 2009).…”

ABSTRACT. Temporal (May 2005 to February 2006 and habitat distribution (pools and riffles) of Hirudinea species was analyzed at a post urban reach from Esquel stream (Chubut province, Patagonia, Argentina). Site was located 5.7 km downstream a Waste Treatment Plant. Mean values of nutrients: ammonia, nitrates and soluble reactive phosphate, as well water conductivity, turbidity and total suspended solids indicated physical and organic pollution. Leeches assemblage was composed by the glossiphonids: Helobdella scutifera Blanchard, 1900, H. michaelseni (Blanchard, 1900, H. simplex (Moore, 1911), Helobdella sp., H. hyalina Ringuelet, 1942, H. obscura Ringuelet, 1942 and the semiscolecid Patagoniobdella variabilis (Blanchard, 1900). From these H. hyalina and H. obscura are new records for Chubut province. Helobdella hyalina (810 ind.m -2 ) and H. simplex (465 ind. m -2 ) clearly dominated the assemblage at the reach. Only H. simplex displayed a spatial preference being significantly more abundant in pools than in riffle habitats (p<0.001). Species recruitment occurred mostly at September, December and March when juveniles were very abundant. Although several species of Helobdella were able to live in the disturbed section of the stream, only H. simplex and H. hyalina sustained large populations at the site and can be considered as tolerant to organic enrichment. This information is valuable to future studies on stream condition assessment in mountainous areas in Patagonia, and in other areas in which these species are present.

“…Restoration of diverse communities in modified streams and rivers relies on achieving effective connectivity for the wide range of native fishes rather than just a few select species Langford et al 2009;Gough et al 2012). For fish communities, hydromorphological impacts are among the greatest problems to achieving good ecological functionality of streams and rivers, for example as expressed in the WFD (Kemp and O'Hanley 2010).…”

“…For example, improvements in water quality and physical habitat diversity, and reinstatement of more natural hydraulic connectivity may be needed to support a more abundant and diverse fish assemblage (Van Dijk et al 1995;Bernhardt and Palmer 2007). Degraded aquatic communities can recover from past environmental insults only if recolonization opportunities are provided (Langford et al 2009). Where past pollution incidents, for example, have eliminated populations in river reaches, recolonization requires dispersal from adjacent population sources.…”

AbstractA more holistic approach towards testing longitudinal connectivity restoration is needed in order to establish that intended ecological functions are achieved. We illustrate the use of a multi-method scheme to evaluate the effectiveness of 'nature-like' connectivity restoration for stream fish communities in the River Deerness, NE England. Electric-fishing, capture-mark-recapture, PIT telemetry and radio-telemetry were used to measure fish community composition, dispersal, fishway efficiency and upstream migration respectively. For measuring passage and dispersal, our rationale was to evaluate a wide size range of strong swimmers (exemplified by brown trout Salmo trutta) and weak swimmers (exemplified by bullhead Cottus perifretum) in situ in the stream ecosystem. Radiotracking of adult trout during the spawning migration showed that passage efficiency at each of five connectivity-restored sites was 81.3-100%. Unaltered (experimental control) structures on the migration route had a bottle-neck effect on upstream migration, especially during low flows.However, even during low flows, displaced PIT tagged juvenile trout (total n = 153) exhibited a passage efficiency of 70.1-93.1% at two nature-like passes. In mark-recapture experiments juvenile brown trout and bullhead tagged (total n = 5303) succeeded in dispersing upstream more often at most structures following obstacle modification, but not at the two control sites, based on a Laplace kernel modelling approach of observed dispersal distance and barrier traverses. Short-term post-restoration data (2-3 years) showed that the fish assemblage remained similar at five of six connectivity-restored sites and two control sites, but at one connectivity-restored headwater site previously inhabited by trout only, three native non-salmonid species colonised. We conclude that stream habitat reconnection should support free movement of a wide range of species and life stages, wherever retention of such obstacles is not needed to manage non-native invasive species. Evaluation of the effectiveness of fish community restoration in degraded streams benefits from a similarly holistic approach.
