Abstract	We evaluated the ecological integrity of Andean Patagonia urban streams by assessing changes in leaf litter decomposition rates and benthic invertebrate assemblage colonizing litter. Urban streams had higher nutrient concentrations and temperatures, and lower flow variability than cold-temperate oligotrophic Patagonia Andes streams. Leaf litter decomposition was faster in urban streams (50% higher than reference streams) mainly attributable to microbial decomposition; urban effect size in fine mesh (FM) bags was two-fold than in reference streams in coincidence with high nutrient concentrations and temperatures. Leaf litter decomposition had a similar effect in coarse mesh (CM) and FM bags, suggesting that invertebrate detritivore feeding activity was poor in urban streams. This was apparent when the effect of temperature on litter decay in CM bags was removed and urban effect size was nil. Invertebrates showed 71.5% dissimilarity between stream types, with higher tolerant species dominating urban streams. Functional feeding groups strongly varied between urban and reference streams over time, with shredders being the most contributing group in reference streams, and collector-gatherers, scrapers, and shredders contributing to urban streams. Our results highlight the avail of including functional studies to understanding the effect of human alterations on small streams complementing the analysis of ecosystem structure.

Abstract	Andean Patagonia is experiencing sudden changes due to unorganized urban expansion. Despite being known for its wilderness areas, southern Patagonian urban streams have been increasingly studied during the last decade, using reference-impact gradients within urbanizing watersheds. Here, we assess urbanization effects on stream integrity by comparing environmental characteristics on independent reference streams vs. urban streams, and the benthic macroinvertebrate community structure along three stream reaches in an urbanization gradient. In comparison to reference sites, urban streams had higher nutrient concentrations, temperature, turbidity, stream flow, and total primary producer biomass, accompanied by lower dissolved oxygen concentrations, substrate particle size, mainly along mid and downstream areas. These variables were the main factors structuring macroinvertebrate assemblage ordination analysis. Macroinvertebrate assemblages from areas upstream from the urbanization differed from their counterparts in reference streams, but not from downstream reference areas. Environmental characteristics and biotic assemblage structure were altered in urban streams, even in reaches located upstream from urbanization, compared to independent upstream reference reaches. This study highlights the importance of a community and comparative vision towards independent areas with low impact to serve as reference values and establish appropriate goals or baselines when assessing ecological conditions and potential restoration.

Article: Assessment of metal exposure (uranium and copper) in fatty acids and carbohydrate profiles of Calamoceras marsupus larvae (Trichoptera) and Alnus glutinosa leaf litter

Abstract	Physiological changes were explored in fatty acids (FA) and carbohydrate (CHO) composition in the shredder Calamoceras marsupus larvae (Trichoptera) and leaf litter (C. marsupus food) exposed to copper and uranium under natural and experimental conditions. We measured FA and CHO content in leaf litter and larvae specimens from reference and impacted streams, and exposed for 5 weeks to four realistic environmental concentrations of copper (35 μg L⁻¹ and 70 μg L⁻¹) and uranium (25 μg L⁻¹ and 50 μg L⁻¹). Regarding FA, (1) leaf litter had a reduced polyunsaturated FA (PUFA) content in metal treatments, s (14 to 33% of total FA), compared to natural conditions (≥39% of total FA). Leaf litter exposed to uranium also differed in saturated FA (SFA) composition, with lower values in natural conditions and higher values under low uranium concentrations. (2) C. marsupus had/showed low PUFA content under Cu and U exposure, particularly in high uranium concentrations. Detritivores also decreased in PUFA under exposure to both metals, particularly in high uranium concentrations. On the other hand, (1) microorganisms of the biofilm colonizing leaf litter differed in CHO composition between natural (impacted and reference) and experimental conditions, with glucose and galactose being consistently the most abundant sugars, found in different amounts under copper or uranium exposure; (2) CHO of detritivores showed similar high galactose and fucose concentrations in contaminated streams and high copper treatments, whereas low copper treatment showed distinct CHO profiles, with higher mannose, glucose, arabinose, and fucose concentrations. Our study provides evidence of metal exposure effects on FA and CHO contents at different trophic levels, which might alter the quality of food flow in trophic webs.

Abstract	Galled leaves are very frequent in southern beech (Nothofagus pumilio) forests. We compared the consumption of leaves (galled and ungalled) by two detritivores and the effect of this consumption on detritivore nutrient content. The amphipod Hyalella curvispina and larvae of the caddisfly Monocosmoecus hyadesi were fed with two diet treatments for 30 days: (1) ungalled leaves and (2) galled leaves. Fungal biomass, carbon (C), nitrogen (N), and phosphorus (P) content were measured in leaves and detritivores, and C:N:P molar ratios were calculated. We hypothesized that galls produce changes in litter nutrient content, affecting invertebrate consumption and nutrient content. Galled leaves had higher N and ergosterol content, and lower C:N ratios than ungalled leaves. Galled leaf consumption was higher than the ungalled for both detritivores. The two species differed in the content of N and C (caddisfly > amphipod) and P (caddisfly < amphipod). The N:P ratio of the amphipods was similar to the ungalled leaf ratio and increased when fed on galled leaves. In contrast, the N:P ratio of the caddisflies was considerably higher than the ungalled leaves and decreased when fed on galled leaves. Galls alter nutrient content in leaves and increase fungal biomass. Both detritivore species were highly homeostatic with regard to C:N ratio, but caddisflies could overcome the limited P content by increasing consumption. We highlight the impact of galls on aquatic detritivores, which in turn are relevant in forested streams for recycling organic matter and cascading effects through brown detritus-based aquatic food webs.

Abstract	The Santa Cruz River is the last free-flowing river in Argentinean Patagonia. Two dams are projected, and no comprehensive pre-impoundment study has been undertaken. The present study investigated macroinvertebrate communities along three different hydrological periods and at three river sections located upstream and downstream of future dams. Fifty-three macroinvertebrate taxa were identified, with the most abundant orders being Ephemeroptera, Plecoptera, Coleoptera, and Crustacea (particularly amphipods). Ordination methods (CCA) and generalized linear models (GLM) were applied. According to the CCA, the main environmental variables related to macroinvertebrate density were temperature, suspended solids, depth, and substrate size. For the GLM, the main factors associated with macroinvertebrate abundance were location and hydrological period, and variables with the highest influences were temperature, substrate size, current speed, and depth. We anticipate that dam construction will modify in-stream habitat conditions, leading to changes in (i) macroinvertebrate community structure and (ii) local fish abundance due to loss of key prey taxa.

Abstract	Environmental pollution with toxic trace metals is of great concern for the environment and for public health. Here we assess the response of the shredder caddisfly Calamoceras marsupus to sub-lethal exposures to copper and uranium. As endpoints we used growth, feeding and growth efficiency, and a set of enzyme biomarkers (oxidative stress: glutathione-S-transferase and catalase; respiration: lactate dehydrogenase; and the activities of acetylcholinesterase and Na+/K+-adenosine triphosphatase). We found that survival, growth, feeding and growth efficiency were not affected by any of the copper (0, 35 and 70μgL−1) or uranium (0, 25 and 50μgL−1) conditions. However, catalase activity increased with increased copper concentration, from 0.20 to 0.85nmolmin−1mg−1 protein (mean±SE; p<0.0001). Na+/K+ ATPase activity decreased with increased U concentration (from 0.16±0.01 to 0.11±0.01; mean±SE; p<0.001). The activities of LDH, GST and AChE enzymes did not differ across treatments. We concluded that CAT and Na+/K+-ATPase were the most sensitive biomarkers for copper and uranium respectively, at concentrations below levels that would affect growth and feeding.

Abstract	Diet overlap between the native Puyen (Galaxias maculatus) and juvenile exotic Rainbow Trout (Oncorhynchus mykiss) was studied in 52 sites located along 306 km of the mainstem of the Santa Cruz River, one of the largest rivers in Patagonia. The relative abundance of both species varied along the river, with three clearly defined areas including an upstream “high Rainbow Trout to Puyen ratio” area (with abundances of 75 and 25 %, respectively), a midstream “intermediate Rainbow Trout to Puyen ratio” area (relative abundances between 75 and 25 %), and a downstream “low Rainbow Trout to Puyen ratio” area. The diet of the 2 species was analyzed across these 3 areas examining stomach content. Diet similarity between species was analyzed using a non-metric multidimensional scaling ordination technique; prey electivity was evaluated with the Ivlev’s Index; feeding tactics were studied by estimating prey-specific abundance. Both species showed a generalist feeding tactic, with Puyen exhibiting a more varied diet. Prey electivity was similar in both species, with the mayfly (Meridialaris chiloeensis), stoneflies (Klapopteryx kuscheli and Antarctoperla michaelseni), and the amphipod (Hyalella sp.) being the most frequently consumed prey. A significant diet overlap was found only in the downstream areas where a higher proportion of native fish occurs. The low diet overlap in upstream locations might be because of the high density of Rainbow Trout; while mid-stream could be due to the high secondary productivity spots. Our results suggest that the diet of native Puyen changed in relation to the abundances of Rainbow Trout in the stream.

Abstract	Three large rivers have their headwaters in the Patagonian Ice Fields (PIFs) in the Andes Mountains, the largest mid-latitude ice masses on Earth: Santa Cruz, Baker and Pascua. They are the last large free flowing rivers in Patagonia, but plans are advanced for building dams for hydroelectric power generation. The three PIF rivers, with a discharge dominated by ice melt, share a common, unique hydrograph compared to that of the other eight large rivers in the region: a distinct seasonal cycle, and an extremely stable discharge, with much lower variability than other rivers. In this study we present the first extensive survey of habitats and benthic macroinvertebrates in the least studied system, the Santa Cruz River. We assess how much of the natural capital provided and sustained by benthic invertebrates are expected to be lost by flooding and discuss how dams would affect riverine habitat and biota. In the Santa Cruz River, we conducted an intensive field survey during September 2010; a total of 52 sites located at regular 6km intervals were sampled along the 310 river-km for macroinvertebrates and seventeen habitat variables. Although some habitat structure is apparent at the local scale, the Santa Cruz River could be described as very homogeneous. Macroinvertebrate density and the richness (38 genera) found in the Santa Cruz River resulted to be one of the lowest in comparison with 42 other Patagonian rivers. Albeit weak, the structure of the macroinvertebrates assemblages was successfully described by a reduced set of variables. The reduced flow variation and the lack of bed scouring flows have a direct and negative effect on the heterogeneity of riverbeds and banks. The high turbidity of the Santa Cruz River may also contribute to shorter food webs, by affecting autotrophic production, general trophic structure, and overall macroinvertebrate productivity and diversity. Dams will obliterate 51% of the lotic environment, including the most productive sections of the river according to our macroinvertebrate data. Since Santa Cruz River has a naturally homogeneous flow cycle, dams may provide more variable flows and more diverse habitat. Our data provide critically valuable baseline information to understand the effects of dams on the unique set of glacial driven large rivers of Patagonia.

Abstract	The Neotropical region hosts 4225 freshwater fish species, ranking first among the world's most diverse regions for freshwater fishes. Our NEOTROPICAL FRESHWATER FISHES data set is the first to produce a large‐scale Neotropical freshwater fish inventory, covering the entire Neotropical region from Mexico and the Caribbean in the north to the southern limits in Argentina, Paraguay, Chile, and Uruguay. We compiled 185,787 distribution records, with unique georeferenced coordinates, for the 4225 species, represented by occurrence and abundance data. The number of species for the most numerous orders are as follows: Characiformes (1289), Siluriformes (1384), Cichliformes (354), Cyprinodontiformes (245), and Gymnotiformes (135). The most recorded species was the characid Astyanax fasciatus (4696 records). We registered 116,802 distribution records for native species, compared to 1802 distribution records for nonnative species. The main aim of the NEOTROPICAL FRESHWATER FISHES data set was to make these occurrence and abundance data accessible for international researchers to develop ecological and macroecological studies, from local to regional scales, with focal fish species, families, or orders. We anticipate that the NEOTROPICAL FRESHWATER FISHES data set will be valuable for studies on a wide range of ecological processes, such as trophic cascades, fishery pressure, the effects of habitat loss and fragmentation, and the impacts of species invasion and climate change. There are no copyright restrictions on the data, and please cite this data paper when using the data in publications.
