Initial Odonata larval distributions are primarily influenced by adult females at the moment of oviposition. However, after oviposition, the larvae are strongly associated with environmental conditions. In the case of both adults and larvae, anthropogenic disturbances that change these conditions may alter the composition and structure of Odonata assemblages. Therefore, based on the differing environmental requirements of Zygoptera and Anisoptera adults and larvae, together with their morphological and physiological differences, we suspected differing riparian preferences of larvae and adults for each suborder. We evaluated the richness and abundance of Odonata larvae. We hypothesized that Zygoptera larvae would have greater richness and abundance in streams with canopy shading, lower temperature ranges, and high physical habitat heterogeneity. On the other hand, Anisoptera larvae would be more abundant in streams without canopy cover. We sampled 186 headwater stream sites in the Neotropical Savanna along an anthropogenic disturbance gradient and used a model selection approach to test our hypotheses, correlating environmental metrics with Odonata larval richness and abundance. We found higher richness of Zygoptera larvae in shaded sites with canopy cover > 5 m high, whereas bare ground without riparian vegetation was important for Anisoptera richness and abundance. Our results indicated that Odonata larvae follow the same distribution, richness and abundance patterns as adults. Anthropogenic disturbances related to the removal or reduction of riparian vegetation can favor Anisoptera over Zygoptera larval assemblages in streams. Preserving riparian canopy cover is needed to maintain the richness of Zygoptera larvae in Neotropical Savanna streams.

The relationship between detritivore diversity and decomposition can provide information on how biogeochemical cycles are affected by ongoing rates of extinction, but such evidence has come mostly from local studies and microcosm experiments. We conducted a globally distributed experiment (38 streams across 23 countries in 6 continents) using standardised methods to test the hypothesis that detritivore diversity enhances litter decomposition in streams, to establish the role of other characteristics of detritivore assemblages (abundance, biomass and body size), and to determine how patterns vary across realms, biomes and climates. We observed a positive relationship between diversity and decomposition, strongest in tropical areas, and a key role of abundance and biomass at higher latitudes. Our results suggest that litter decomposition might be altered by detritivore extinctions, particularly in tropical areas, where detritivore diversity is already relatively low and some environmental stressors particularly prevalent.

Running waters contribute substantially to global carbon fluxes through decomposition of terrestrial plant litter by aquatic microorganisms and detritivores. Diversity of this litter may influence instream decomposition globally in ways that are not yet understood. We investigated latitudinal differences in decomposition of litter mixtures of low and high functional diversity in 40 streams on 6 continents and spanning 113° of latitude. Despite important variability in our dataset, we found latitudinal differences in the effect of litter functional diversity on decomposition, which we explained as evolutionary adaptations of litter-consuming detritivores to resource availability. Specifically, a balanced diet effect appears to operate at lower latitudes versus a resource concentration effect at higher latitudes. The latitudinal pattern indicates that loss of plant functional diversity will have different consequences on carbon fluxes across the globe, with greater repercussions likely at low latitudes.

Over 70% of the total channel length in all river basins is formed by low order streams, many of which originate on mountaintops. Headwater streams play fundamental roles in processing and transporting terrestrial and aquatic organic matter, often harboring high biodiversity in bottom leaf patches deposited from riparian vegetation. The objective of this study was to assess the variation in taxonomic composition (measured by beta diversity of aquatic macroinvertebrates) among stream sites located in the Espinhaço Meridional Mountain Range, part of a UNESCO Biosphere Reserve in eastern Brazil. We tested two hypotheses. (a) Taxa turnover is the main reason for differences in aquatic insect assemblages within stream sites; we predicted that turnover would be higher than nestedness in all stream sites. (b) Stream site altitude and catchment elevation range are the main explanatory variables for the differences in beta diversity; we predicted that local stream site variables would account for only minor amounts of variation. In both dry and wet seasons, we sampled twice in two habitat types (five leaf patches in pools and five in riffles) in each of nine stream sites distributed in three different river basins. We computed average pairwise beta diversity among sampling stations and seasons in each stream site by using Jaccard and Bray–Curtis indices, and calculated the percentages of diversity resulting from turnover and nestedness. Finally, we tested the degree that local‐ or catchment‐level predictor variables explained beta diversity. We found that turnover was the main component of beta diversity and that both dissolved oxygen and elevation range best explained Bray–Curtis beta diversity. These results reinforce the importance of leaf patches in montane (sky islands) Neotropical savanna streams as biodiversity hotbeds for macroinvertebrates, and that both local and landscape variables explained beta diversity.

The biological assessment of rivers i.e., their assessment through use of aquatic assemblages, integrates the effects of multiple-stressors on these systems over time and is essential to evaluate ecosystem condition and establish recovery measures. It has been undertaken in many countries since the 1990s, but not globally. And where national or multi-national monitoring networks have gathered large amounts of data, the poor water body classifications have not necessarily resulted in the rehabilitation of rivers. Thus, here we aimed to identify major gaps in the biological assessment and rehabilitation of rivers worldwide by focusing on the best examples in Asia, Europe, Oceania, and North, Central, and South America. Our study showed that it is not possible so far to draw a world map of the ecological quality of rivers. Biological assessment of rivers and streams is only implemented officially nation-wide and regularly in the European Union, Japan, Republic of Korea, South Africa, and the USA. In Australia, Canada, China, New Zealand, and Singapore it has been implemented officially at the state/province level (in some cases using common protocols) or in major catchments or even only once at the national level to define reference conditions (Australia). In other cases, biological monitoring is driven by a specific problem, impact assessments, water licenses, or the need to rehabilitate a river or a river section (as in Brazil, South Korea, China, Canada, Japan, Australia). In some countries monitoring programs have only been explored by research teams mostly at the catchment or local level (e.g., Brazil, Mexico, Chile, China, India, Malaysia, Thailand, Vietnam) or implemented by citizen science groups (e.g., Southern Africa, Gambia, East Africa, Australia, Brazil, Canada). The existing large-extent assessments show a striking loss of biodiversity in the last 2-3 decades in Japanese and New Zealand rivers (e.g., 42% and 70% of fish species threatened or endangered, respectively). A poor condition (below Good condition) exists in 25% of South Korean rivers, half of the European water bodies, and 44% of USA rivers, while in Australia 30% of the reaches sampled were significantly impaired in 2006. Regarding river rehabilitation, the greatest implementation has occurred in North America, Australia, Northern Europe, Japan, Singapore, and the Republic of Korea. Most rehabilitation measures have been related to improving water quality and river connectivity for fish or the improvement of riparian vegetation. The limited extent of most rehabilitation measures (i.e., not considering the entire catchment) often constrains the improvement of biological condition. Yet, many rehabilitation projects also lack pre-and/or post-monitoring of ecological condition, which prevents assessing the success and shortcomings of the recovery measures. Economic constraints are the most cited limitation for implementing monitoring programs and rehabilitation actions, followed by technical limitations, limited knowledge of the fauna and flora and their life-history traits (especially in Africa, South America and Mexico), and poor awareness by decision-makers. On the other hand, citizen involvement is recognized as key to the success and sustainability of rehabilitation projects. Thus, establishing rehabilitation needs, defining clear goals, tracking progress towards achieving them, and involving local populations and stakeholders are key recommendations for rehabilitation projects (Table 1). Large-extent and long-term monitoring programs are also essential to provide a realistic overview of the condition of rivers worldwide. Soon, the use of DNA biological samples and eDNA to investigate aquatic diversity could contribute to reducing costs and thus increase monitoring efforts and a more complete assessment of biodiversity. Finally, we propose developing transcontinental teams to elaborate and improve technical guidelines for implementing biological monitoring programs and river rehabilitation and establishing common financial and technical frameworks for managing international catchments. We also recommend providing such expert teams through the United Nations Environment Program to aid the extension of biomonitoring, bioassessment, and river rehabilitation knowledge globally.

Aim Changes in land use and cover (hereafter land use) affect freshwater ecosystems at different spatial scales. We tested the effects of land use on the dispersal capacity of stream macroinvertebrates through local and regional processes. Location In all, 183 Brazilian headwater stream sites, located in the Neotropical Savanna with variable land use and covering a total area of 46,394 km2. Taxon Stream macroinvertebrates Methods We used multiple regression models for distance matrices to identify the relative importance of environmental and landscape characteristics to explain community dissimilarity of stream macroinvertebrates with different mobility traits. As predictors, we calculated four distance metrics: environmental distance describing the dissimilarity in local conditions, the network distance accounting for distances across the drainage system and two distances measuring landscape resistance to dispersal (topographic and land use). We classified macroinvertebrates in dispersal groups according to their dispersal abilities (flying and drifting) and life story traits (voltinism, adult life span and body size). We tested the effects of these distances on all taxa and on the different dispersal groups, to explore whether biological traits would result in different metacommunity patterns. Results Our hierarchical clustering analysis identified five macroinvertebrate dispersal groups. The dispersal group 1 was mainly composed by aquatic obligate taxa, dispersal group 2 by taxa with low drift propensity, dispersal group 3 represented taxa with high directional flight capacity, dispersal group 4 included taxa with medium drift propensity and dispersal group 5 represented taxa with high drift propensity. We found that environmental distance and land use distance were the most important predictors explaining community dissimilarity for most of the dispersal groups. Main conclusion The metacommunity patterns found in this study suggest that environmental filtering was the most important community assembly mechanism at a local scale, whereas land use could constrain dispersal at the regional scale. Understanding these processes is crucial to meet conservation and restoration goals, especially in biodiversity hotspots. Our results reinforce the importance of considering entire catchments for preserving stream health and aquatic biodiversity and indicate the need for a much more integrative research between terrestrial and aquatic ecology.

We address the main methodologies for collecting aquatic insects in various aquatic ecosystems and habitat types, describing both field and laboratory procedures. Fourteen insect orders have aquatic forms and can live as larvae, nymphs, or adults in aquatic ecosystems. Special emphasis is presented for different habitat types, and methods for collecting, preparing, and identifying aquatic insects are described. The main methods to collect aquatic insects are described for lotic; lentic; hyporheic zone; spring; marine, brackish, and inland saltwater; phytotelmata; and hygropetric and madicolous habitats. We describe the main methods and materials for collecting aquatic insects in the field, including active (e.g., nets, dredges) and passive (e.g., drift samplers) techniques for larvae and flying adults. Laboratory procedures, specimen preparation, species identification, and conservation and curator issues are described, as well as conservation implications for aquatic insects.

The effects of anthropogenic disturbance on multiple facets of biodiversity are poorly understood. In this study, we worked with the hypothesis that anthropogenic disturbances affect the relationship between environmental heterogeneity (EH) and biodiversity. We used a model selection approach to test three predictions. P1: The greater the level of anthropogenic disturbance, the weaker will be the relationship between EH and both taxonomic and functional alpha diversities. P2: The sign and strength of correlations between EH metrics and both taxonomic and functional alpha diversities will depend on the level of anthropogenic disturbance. P3: Taxonomic and functional beta diversities will not respond to the EH gradient. We sampled 76 stream sites in the Brazilian Neotropical savanna and collected insect of the orders Ephemeroptera, Plecoptera and Trichoptera to measure taxonomic and functional alpha and beta diversities. For P1, we did not find a trend of decreasing strength of this relationship with increasing disturbance. Results confirmed P2. Spatial flow diversity was positively correlated to taxonomic and functional alpha diversities in least-disturbed sites. Bankfull height variation was negatively correlated to taxonomic and functional alpha diversities in moderately-disturbed sites. Thalweg depth variation was positively correlated to taxonomic and functional alpha diversities in most-disturbed sites. Results partially confirmed P3 because taxonomic and functional beta diversities correlated with EH metrics in most-disturbed sites. We conclude that the biodiversity-EH relationship is not the same at all levels of anthropogenic disturbance, a finding that has implications for biomonitoring and ecosystem management.

Riparian zones ensure freshwater ecosystem processes such as microclimate regulation, organic matter inputs, and fine substrate retention. These processes illustrate the importance of riparian zones for freshwater ecosystem functioning, maintaining biodiversity, and mitigating the effects of anthropogenic pressures on aquatic ecosystems. We aimed to determine the freshwater invertebrate biological traits that are most affected by anthropogenic stressors in the riparian zones of 210 Neotropical savanna headwater streams. We assessed % canopy cover over the streambed, % fine bottom substrate, % leaf pack, substrate heterogeneity, and water temperature. Firstly, we identified bioindicator taxa in response to each local metric gradient. We assessed the functional response, based on biological traits of bioindicators previously selected. We identified 324,015 specimens belonging to 84 freshwater invertebrate taxa. Fifty-one taxa (60%) were bioindicators of anthropogenic stressors. We found three main sets of traits. (1) a set of traits linked to increased disturbance (higher percentage of fine sediments), consisting of organisms with aquatic adult stages, spherical body shape, and long adult life stages. (2) A set of traits linked to lower disturbance (higher substrate heterogeneity), including taxa with short or very short lifespans that live attached to substrates. (3) A set of traits linked to higher water temperature, including organisms with short adult lifespans and lower body flexibility. These patterns suggest that the stressors act as environmental filters and do not act independently on single traits, but rather, selecting sets of biological traits that facilitate taxa surviving and persisting in local environmental conditions. Our results support the development of powerful evaluation tools for environmental managers and decision makers. Because degraded freshwater communities respond in similar ways across large biogeographic areas, these sets of traits can be used for ecological monitoring efforts along other tropical savanna headwaters worldwide.

The drivers of dissimilarity in biological communities among habitats and the mechanisms that modulate the distribution of functional diversity in streams are still important gaps in ecological knowledge. This study was designed to assess how the taxonomic and functional composition of Cerrado stream insect assemblages are distributed among multiple spatial scales (i.e., habitat, stream sites and hydrological units). To do so we used a hierarchical series of four diversity components: stream transect (α), among transects (β1), among stream sites (β2), and among hydrological units (β3). Our aim was to identify the spatial scales at which variation in aquatic insect assemblage structure was greatest and whether turnover or nestedness mainly explain the patterns of β-diversity. We found that β-diversity among streams (β2) is highest and contributes most to total richness (γ-diversity) of aquatic insects in Cerrado streams as opposed to dissimilarities among habitats or among hydrological units. Moreover, β-diversity among transects had the lowest contribution to total insect richness (γ-diversity). The turnover component of taxonomic β-diversity was high for all spatial scales, but highest at stream scale. Conversely, for functional β-diversity, nestedness was the main component at stream scale. Understanding how biodiversity changes from local to regional scales is a first step towards understanding the variation in species and trait composition across space. Our results emphasize the importance of conserving Cerrado headwater streams because each stream harbors different taxa and human disturbance of any stream will result in loss of diversity and ecosystem functions.

Reservoirs are a common sight in most rivers systems in the world and a frequent problem related to them is the introduction of non-native invasive mollusk species. We aimed to determine which local variables (near-site land use, physical habitat structure, water quality) were most strongly associated with the local distribution of invasive non-native mollusks in neotropical hydropower reservoirs. We used data from three neotropical reservoirs to calculate which local variables most influenced the presence or absence of the three non-native invasive mollusk species (i.e., Corbicula fluminea, Limnoperna fortunei and Melanoides tuberculata) found in them. We found that the presence of both C. fluminea and L. fortunei were positively correlated with local anthropogenic disturbances, likely because it was associated with more frequent human access to the water body and increased introductions of larval mollusks. Conversely, M. tuberculata was negatively correlated with total phosphorus concentration, which is linked to agriculture and urbanization in the reservoir catchments. Additionally, we found that C. fluminea and M. tuberculata presence was positively related to each other, implying a biological facilitation process between these two species. Our findings suggest that anthropogenic disturbances are important for the local distribution of invasive non-native mollusks in neotropical reservoirs and can be used by environmental managers and decision-makers to help manage invasive mollusk populations in neotropical hydropower reservoirs.

We investigated food preferences, growth and survival of the caddisfly shredder Phylloicus angustior while exposed to leaves of Eucalyptus camaldulensis and three native tree species (Myrcia guianensis, Miconia chartacea, and Protium brasiliense) of the Brazilian Cerrado. Because of the low quality of native leaves, we hypothesized that E. camaldulensis would be preferred and would promote higher growth and survival of shredders than Cerrado species. Except for P. brasiliense, all leaves were consumed in the food preference experiment and E. camaldulensis was preferred to native species. Shredder preferences were similar in an in situ experiment, and the consumption rates did not differ between the laboratory and field conditions. In the monodietary experiment, shredder daily growth rates were positive (4.76–6.83%) and did not differ among leaves. Survival of larvae that fed on E. camaldulensis and M. chartacea was significantly higher than those that fed on M. guianensis and P. brasiliense. Our results showed that E. camaldulensis can be an attractive food resource for P. angustior in Cerrado streams. However, the lack of differences in growth do not fully support the proposed hypothesis and suggests that E. camaldulensis does not constitute a better food resource than native leaves of worse quality.

1. Protecting riparian vegetation around streams is vital in reducing the detrimental effects of environmental change on freshwater ecosystems and in maintaining aquatic biodiversity. Thus, identifying ecological thresholds is useful for defining regulatory limits and for guiding the management of riparian zones towards the conservation of freshwater biota. 2. Using nationwide data on fish and invertebrates occurring in small Brazilian streams, we estimated thresholds of native vegetation loss in which there are abrupt changes in the occurrence and abundance of freshwater bioindicators and tested whether there are congruent responses among different biomes, biological groups and riparian buffer sizes. 3. Mean thresholds of native vegetation cover loss varied widely among biomes, buffer sizes and biological groups: ranging from 0.5% to 77.4% for fish, from 2.9% to 37.0% for aquatic invertebrates, and from 3.8% to 43.2% for a subset of aquatic invertebrates. Confidence intervals for thresholds were wide, but the minimum values of these intervals were lower for the smaller riparian buffers (50 and 100 m) than larger ones (200 and 500 m), indicating that land use should be kept away from the streams. Also, thresholds occurred at a lower percentage of riparian vegetation loss in the smaller buffers, and were critically lower for invertebrates: reducing only 6.5% of native vegetation cover within a 50‐m riparian buffer is enough to cross thresholds for invertebrates. 4. Synthesis and applications. The high variability in biodiversity responses to loss of native riparian vegetation suggests caution in the use of a single riparian width for conservation actions or policy definitions nationwide. The most sensitive bioindicators can be used as early warning signals of abrupt changes in freshwater biodiversity. In practice, maintaining at least 50‐m wide riparian reserves on each side of streams would be more effective to protect freshwater biodiversity in Brazil. However, incentives and conservation strategies to protect even wider riparian reserves (~100‐m) and also taking into consideration the regional context will promote a greater benefit. This information should be used to set conservation goals and to create complementary mechanisms and policies to protect wider riparian reserves than those currently required by the federal law.

Accurate and precise detection of anthropogenic impacts on stream ecosystems using macroinvertebrates as biological indicators depends on the use of appropriate field and laboratory methods. We assessed the responsiveness to anthropogenic disturbances of assemblage metrics and composition by comparing commonly employed alternative combinations of field sampling and individuals counting methods. Four datasets were derived by, in the field 1) conducting multihabitat sampling (MH) or 2) targeting samples in leaf packs (single-habitat sampling – SH) and, in the laboratory A) counting all individuals of the samples, or B) simulating subsampling of 300 individuals per sample. We collected our data from 39 headwater stream sites in a drainage basin located in the Brazilian Cerrado. We used a previously published quantitative integrated disturbance index (IDI), based on both local and catchment disturbance measurements, to characterize the intensity of anthropogenic alterations at each site. Family richness and % Ephemeroptera, Plecoptera and Trichoptera (% EPT) individuals obtained from each dataset were tested against the IDI through simple linear regressions, and the differences in assemblage composition between least- and most-disturbed sites were tested using Permutational Multivariate Analysis of Variance (PERMANOVA). When counting all individuals, differences in taxonomic richness and assemblage composition of macroinvertebrate assemblages between least- and most-disturbed sites were more pronounced in the MH than in the SH sampling method. Leaf packs seemed to concentrate high abundance and diversity of macroinvertebrates in highly disturbed sites, acting as ‘biodiversity hotbeds’ in these situations, which likely reduced the response of the assemblages to the disturbance gradient when this substrate was targeted. However, MH sampling produced weaker results than SH when subsampling was performed. The % EPT individuals responded better to the disturbance gradient when SH was employed, and its efficiency was not affected by the subsampling procedure. We conclude that no single method was the best in all situations, and the efficiency of a sampling protocol depends on the combination of field and laboratory methods being used. Although the total count of individuals with multihabitat sampling obtained the best results for most of the evaluated variables, the decision of which procedures to use depends on the amount of time and resources available, on the variables of interest, on the availability of habitat types in the sites sampled, and on the other methods being employed in the sampling protocol.

Tackling complex environmental issues requires transdisciplinary solutions that cannot be achieved, unless we integrate scientific disciplines and communicate science directly with civil society actors, decision-makers, and stakeholders. Alexander von Humboldt offered an approach to integrate knowledge across disciplines aiming to broadly understand human-environmental issues, yet current scientific practices largely ignore that holistic transdisciplinary approach. Here, we develop a conceptual framework for sustaining mountain environmental integrity and securing their ecosystem services based on transdisciplinarity. We use headwater systems located in old tropical mountains as examples of meta-ecosystems because they supply water for multiple human uses and are home to disproportionately high levels of species richness and endemism. We describe the vulnerability of mountains to global changes in the Anthropocene and discuss difficulties in implementing sustainable development goals for them. Specifically, we indicate the importance of mountains to human water supplies and the conflicts between anthropogenic disturbances and riparian stream meta-ecosystems for providing ecosystem services particularly failures. We also argue that the interplay between academia and other sectors of society must improve and increase the permeability of scientific knowledge into policy- and decision-making, which is crucial for improving natural resource management and sustaining ecosystem services. We argue that the prioritization of tropical montane headwater systems is a feasible, desirable and strategic issue to be included in the global sustainability agenda. Failure to implement sustainable development goals in global mountains is likely to continue resulting in catastrophic events with harsh consequences for both humans and global biodiversity.

The quality and availability of water resources in tropical watersheds are threatened by increased multiple use demands by human populations. Therefore, there is a need for cost-effective ecological indicators of water body status and trends. Multimetric indices (MMIs), based on responses of biological assemblages to anthropogenic disturbances, are excellent examples of such indicators and they have been applied globally. However, creating new MMIs for each water body or study area requires considerable analytical effort and hinders our ability to make regional or global comparisons. Therefore, we tested the effectiveness of 17 published benthic macroinvertebrate MMIs for assessing the environmental quality of a tropical anthropogenically least-disturbed river basin in the Neotropical Savanna (Brazilian Cerrado) biome. We tested those MMIs through use of macroinvertebrate data sampled at 40 stream sites in the Pandeiros River basin, Brazil. Disturbances in the basin were related to local factors such as pasture, garbage, and cropland in stream riparian areas. Index performance was tested by comparing precision, bias, responsiveness and sensitivity to anthropogenic pressures and stressors. Ten indices performed satisfactorily in evaluating the environmental condition of the basin. Therefore, we do not recommend developing new benthic MMIs for rapid environmental quality assessments. On the other hand, we do recommend using standard data collection methods for evaluating conditions throughout the biome.

Water level regulation is one of the most common anthropogenic disturbances of lentic ecosystems, which is especially evident in shallow lakes. The objective of this study was to assess the ecological effects of water level regulation in a shallow lake using thermodynamic indicators to support decision makers in a dam decommissioning process. For that we tested three hypotheses: 1) the regulated lake supports lower taxonomic diversity than the naturally fluctuating lake; 2) the structure of the benthic macroinvertebrate assemblage is different in the regulated lake than in the naturally fluctuating lake; 3) the regulated lake supports less complex benthic macroinvertebrate assemblages than the naturally fluctuating lake. Our results show that the first hypothesis, tested using taxa richness, Shannon-Wiener and Simpson diversity indices, was not validated. The second hypothesis was tested using taxonomic composition and was validated, with the two types of lakes exhibiting dissimilar macroinvertebrate assemblages. The third hypothesis, tested using two thermodynamic based indicators, eco-exergy and specific eco-exergy, was partially supported, which was illustrated, overall, by higher eco-exergy (degree of complexity) of the benthic assemblages in the naturally fluctuating lake, although the specific eco-exergies (capacities to use external energy resources) were similar. As a whole, our results endorse the importance of natural water level fluctuations as a driving force in shallow lake ecosystems and reinforced the idea that dam decommissioning is a good option for restoring natural conditions in this type of ecosystem.

In many countries of the Global South, aquatic ecosystems such as streams, rivers, lakes, and wetlands are severely impacted by several simultaneous environmental stressors, associated with accelerated urban development, and extreme climate. However, this problem receives little attention. Applying a DPSIR approach (Drivers, Pressures, State, Impacts, Responses), we analyzed the environmental impacts and their effects on urban hydrosystems (including stagnant waters), and suggest possible solutions from a series of case studies worldwide. We find that rivers in the Global South, with their distinctive geographical and socio-political setting, display significant differences from the Urban Stream Syndrome described so far in temperate zones. We introduce the term of ‘Southern Urban Hydrosystem Syndrome’ for the biophysical problems as well as the social interactions, including the perception of water bodies by the urbanites, the interactions of actors (e.g., top-down, bottom-up), and the motivations that drive urban hydrosystem restoration projects of the Global South. Supported by a synthesis of case studies (with a focus on Brazilian restoration projects), this paper summarizes the state of the art, highlights the currently existing lacunae for research, and delivers examples of practical solutions that may inform UNESCO’s North–South–South dialogue to solve these urgent problems. Two elements appear to be specifically important for the success of restoration projects in the Global South, namely the broad acceptance and commitment of local populations beyond merely ‘ecological’ justifications, e.g., healthy living environments and ecosystems with cultural linkages (‘River Culture’). To make it possible implementable/practical solutions must be extended to (often poor) people having settled along river banks and wetlands.

Local factors, such as riparian vegetation and stream type, affect the structure and composition of benthic macroinvertebrate assemblages in streams. To better understand the effects of biomes on lotic ecosystems, we evaluated whether Atlantic Forest (AF) and Neotropical Savanna (NS) biomes showed distinct patterns in (i) benthic macroinvertebrate assemblage structure and (ii) the shredder functional feeding group. We predicted that (i) richness, density, biomass, instant secondary production, eco-exergy, and specific eco-exergy would be higher for benthic macroinvertebrate assemblages in AF stream sites than in NS sites. We also predicted that (ii) length, density, biomass, instant secondary production, eco-exergy, and specific eco-exergy would be higher for shredders in AF stream sites. We found that benthic macroinvertebrate assemblage composition and taxa richness were significantly different between stream sites in the two biomes, with the AF biome being the richest. But we found no differences in density, biomass, instant secondary production, eco-exergy, or specific eco-exergy between AF and NS stream sites. For AF shredders, the mean length, density, biomass, secondary production and eco-exergy were significantly higher than for NS stream sites. These differences were attributed to the quality of leaf litter, which was generally higher in AF than in NS stream sites. This indicates that the intrinsic characteristics of the AF and NS biomes act as structuring factors for benthic macroinvertebrate assemblages, influencing the structure and functioning of tropical lotic ecosystems.
