Encounters (or interactions) between plastic debris and wildlife can cause great harm to individuals and populations. The most common encounters are ingestion, entanglement and plastic usage (plastic as nesting material, vector for biota transport and refuge/shelter). Hundreds of plastic-encounters have been reported for marine species. However, there is a lack of studies reporting encounters in other ecosystems, such as freshwater and terrestrial ones. Based on a citizen science approach, we documented and analyzed 90 different cases of macroplastic-fauna encounters for 44 freshwater and terrestrial species. Herein, we provided evidence (photographically documented) of the negative consequences of macroplastic debris discarded in freshwater and terrestrial environments. Birds were by far the taxon most frequently reported in encounters (72.2% of the encounters, 30 different species). The dominant type of plastic-fauna encounter was the use of plastic as nesting material (42% of the total cases) and the second one was entanglement (33%). Most of the entanglements had lethal consequences for the organisms involved (almost 60%). Entanglement in ghost fishing gear and bottle (security) rings were particularly dangerous and comparatively frequent in this study. Some invasive species could benefit from the encounters to the detriment of the environment's health, using plastics as settlement substrata. Finally, we lay the foundation for creating worldwide lists of non-marine species impacted by encounters with plastic debris.

Plastics are dominant pollutants in freshwater ecosystems worldwide. Scientific studies that investigated the interaction between plastics and freshwater biodiversity are incipient, especially if compared to the marine realm. In this review, we provide a brief overview of plastic pollution in freshwater ecosystems around the world. We found evidence of plastic ingestion by 206 freshwater species, from invertebrates to mammals, in natural or semi-natural ecosystems. In addition, we reported other consequences of synthetic polymers in freshwater ecosystems—including, for instance, the entanglement of animals of different groups (e.g., birds). The problem of plastic pollution is complex and will need coordinated actions, such as recycling programs, correct disposal, stringent legislation, regular inspection, replacement of synthetic polymers with other materials, and ecological restoration. Current information indicates that the situation in freshwater ecosystems may be as detrimental as the pollution found in the ocean, although highly underappreciated.

Plastic pollution has become a globally pressing environmental issue. In birds, plastic may cause harm by entangling or ingestion when used for nesting. The use of anthropogenic nesting material has so far been mostly studied in birds of terrestrial or marine habitats, but there are yet very few reports for inland water–associated birds. The aim of this study is to better understand the extension and magnitude of the use of anthropogenic debris as nesting material by the greater thornbird (Phacellodomus ruber), a bird species preferably nesting in river floodplain wetlands in South America. We found that P. ruber uses disproportionally large quantities of plastic debris as nesting material (more than 90% of some nest chambers is plastic). This occurred even if ample vegetation (commonly used as soft material) was available. Most of the artificial nesting material was derived from wrapping material released into the environment. We suggest that this species has the potential to indicate vulnerable areas to plastic pollution associated with urban waste mismanagement.

The Turkish Straits System (TSS) is a dangerous and narrow waterway extending between the Black Sea and the Aegean Sea, including the Bosphorus, the Dardanelles, and the Marmara Sea and the Gulf of Izmit. The western banks of the TSS constitute the geographic starting point of the European continent, while the banks to the east are the beginnings of the Asia. TSS is considered one of the most strategically significant waterways of the world. This waterway is the main trading routes linking the Black Sea riparian countries to the world markets. As a result, the density in marine traffic through the TSS has recently reached alarmingly high levels. The aim of this study was to estimate the amount of plastic waste generated aboard merchant ships during their passage through the TSS during the period 2006–2017. This potential resource of waste would potentially impact on the Marmara Sea and its natural environment. The results of this study revealed that merchant ships crossing the TSS generated an average of 187.6 m3 of plastic waste per year. This result suggests that the threat given by the ships crossing this strait is approximately 1% of the total amount of waste recorded in the TSS coastals.

La incógnita planteada en el título reunió a un grupo de investigadores en el simposio “Ecología de residuos plásticos: ¿Qué estudiamos en Argentina?”, llevado a cabo en la XXVIII Reunión Argentina de Ecología. En esta comunicación hacemos un análisis del contexto nacional sobre residuos plásticos. Nuestros estudios en ecología de plásticos buscaron mitigar, por un lado, y cuantificar los residuos plásticos, por otro lado. Estos estudios ocurrieron en la mitad norte del país, en ambientes terrestres y acuáticos, y se enfocaron en diferentes materiales plásticos y en distintos organismos, aunque las bacterias fueron de interés para la mayoría de nosotros. Concluimos con preguntas guía para ecólogos, basadas en los Objetivos de Desarrollo Sostenible (ODS) de la ONU. Estas preguntas se relacionan con los ODS Agua Limpia y Saneamiento, Ciudades y Comunidades Sostenibles, Producción y Consumo Responsable y Vida Submarina y Sobre la Tierra.https://doi.org/10.25260/EA.20.30.1.0.913

This study investigated the presence of microplastics (MPs) in the gastrointestinal tracts of four fish species from the estuarine Ciénaga Grande de Santa Marta (CGSM) in northern Colombia. Of the 140 fish purchased at a local market, 17 (12.1%) were found to contain MPs as confirmed by FT-IR analysis. Among the four different species, Mugil incilis (mullet) showed the highest MP prevalence with just over a fifth of the individuals containing MPs in their gastrointestinal tracts (10 out of 46 (frequency of MP occurrence in %) FO% = 21.7%). This was followed by Caranx hippos (crevalle jack, 2 out of 19 (FO% = 10.5%)), Caquetaia kraussii (yellow mojarra, 3 out of 35 (FO% = 8.6%)), and Eugerres plumieri (striped mojarra, 2 out of 40 (FO% = 5.0%)). From the 17 fish, only 19 MPs were found of which 17 (89.5% were fibers) and 2 (10.5%) were fragments. While polyester and polyethylene were the most common fibers, nylon, acrylic, polyethylene, and modacrylic were also identified suggesting a wide variety of origins and sources. These finding provide the first evidence of MP ingestion by resident fish species in Colombian estuarine waters. Since the region has been variously recognized as being of regional and international importance (i.e., RAMSAR site in 1998 and UNESCO Biosphere Reserve in 2000), we advocate the ongoing investigation of MP pollution in both the environment and biota.

This study examines the effects of the flow and flood pulses on spatial dispersion of fish assemblages in the floodplain of the Paraná River in Argentina. We tested the hypothesis that high water levels and greater lateral connectivity promote fish dispersal and spatial homogenization of assemblage structure. We sampled four sites during different phases of the annual hydrologic cycle from 2010 to 2016. Water surface in the area was estimated during each phase. We computed multivariate statistics and estimates of ß‐diversity to analyze assemblage variations in relation to hydrological phases. Three hydrological phases were defined: low flow pulses (water levels between 2.3 and 3.2, approximately 10% of the floodplain covered by water), high flow pulses (between 3.2 and 4.5, from 11 to 84%), and floods (> 4.5 m, more than 84%). Although difference between high flow pulses and flood was not significant, ß‐diversity values for these stages were higher than for low flow pulses. This suggests that floods and high flow pulses increase the spatial variability of fish assemblages, whereas homogenization processes occur later during low flow periods. This work provides further knowledge about the flood homogenization effect in a large unregulated floodplain where lateral connectivity still plays a significant role on ecological structuring processes.

This paper deals with the hydrological variability effects on the primary commercial fish species inhabiting the main channel and the floodplain of the large Paraná River in its middle reaches in Argentina. Analysing more than eight decades (1935–2016) of information on the most frequent and abundant commercial species in conjunction with hydrological levels and temperature, our results show that spring–summer floods of a certain magnitude (c. 6 m) and durations (> 80 days) are crucial for sustaining commercial fisheries. Moreover, the frequency of these floods was modulated by the decadal climatic fluctuations that have occurred over the past 100 years in the Paraná Basin. An insight into the probable incidence of some anthropogenic influences is also provided. This article is protected by copyright. All rights reserved.

The aim of this study was to determine the amount, composition and origin of plastic debris in one of the world largest river, the Paraná River in Argentina (South America), focusing on the impact of urban rivers, relationships among macro, meso and microplastic, socio-political issues and microplastic ingestion by fish. We recorded a huge concentration of macroplastic debris of domestic origin (up to 5.05 macroplastic items per m2) dominated largely by bags (mainly high- and low-density polyethylene), foodwrapper (polypropylene and polystyrene), foam plastics (expanded polystyrene) and beverage bottles (polyethylene terephthalate), particularly downstream from the confluence with an urban stream. This suggests inadequate waste collection, processing and final disposal in the region, which is regrettably recurrent in many cities of the Global South and Argentina in particular. We found an average of 4654 microplastic fragments m−2 in shoreline sediments of the river, ranging from 131 to 12687 microplastics m−2. In contrast to other studies from industrialized countries from Europe and North America, secondary microplastics (resulting from comminution of larger particles) were more abundant than primary ones (microbeads to cosmetics or pellets to the industry). This could be explained by differences in consumer habits and industrialization level between societies and economies. Microplastic particles (mostly fibres) were recorded in the digestive tract of 100% of the studied Prochilodus lineatus (commercial species). Contrary to recently published statements by other researchers, our results suggest neither macroplastic nor mesoplastics would serve as surrogate for microplastic items in pollution surveys, suggesting the need to consider all three size categories. The massive plastic pollution found in the Paraná River is caused by an inadequate waste management. New actions are required to properly manage waste from its inception to its final disposal.

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.

Plastic pollution is one of the most acute environmental topics of our time. While there is a great scientific effort to tackle this problem, it has not always been well-coordinated or properly targeted. In this short review, we call for scientists to get involved in three crucial topics (threats) underestimated—or ignored—in freshwater systems: (i) plastic-species entanglement, (ii) plastic as nesting material, and (iii) macroplastic debris coming from mismanaged household solid waste. Reducing the knowledge gaps between marine and freshwater environments will be crucial to solute the plastic pollution problem effectively and globally. Therefore, we make a plea here to reinforce research activities on these three issues in freshwater environments worldwide.

The eutrophication of waterways has become an endemic global problem. Nutrient enrichment from agriculture activities and waste water treatment plants are major drivers, but it remains unclear how lowland sandy rivers respond to eutrophication. The objective of this study was the development and verification of eutrophication index for sandy rivers (EISR) to prioritize nutrient enrichment river stretches caused by different land use activities that include point and nonpoint sources of nutrient enrich water. The Berg River drainage system in South Africa served as a case study area for this purpose during the dry seasons (December and January) of 2015 and 2016. In the initial EISR development phase, periphyton, benthic biomass (chl‐a mg m−2), and macroinvertebrate families were employed as benthic bioindicators of river bedforms, whereas in the second phase, physicochemical and abiotic variables were used as target indicator. Using a weight of support approach, the site receiving sewage effluent was categorize as heavily polluted whereas sites impacted by agriculture land use activities were polluted. The EISR that focuses strongly on benthic bioindicators, which are close to the transfer of nutrients and energy in the food web, showed a distinct difference between river bedform impacted by sewage effluent and agriculture none point source. A maximum benthic algae biomass of 110 mg m−2 chl‐a was recorded with higher sediment orthophosphate concentration at sewage‐impacted sites. The outcome of the proposed EISR showed that it can be employed as a decision support tool for eutrophication management of sandy rivers.

The aim of the current study was to determine the ecological role of anabranch confluences at diverse hydrological regimes, taking into consideration floodplain secondary channels of a large river as a case of study. In conducting this study, we used unpublished data from sampling campaigns performed in the past. Triplicate benthic sediment samples were taken at each station using a bottom grab and according to sampling protocols equal to the current ones. Benthic taxa were identified at the species and genus levels. According to our results, a protracted effect by the ENSO phenomenon on benthic fauna structure was evident. This effect was not only observed in the confluences but all along the rivers, reflecting its ecological effect at least one and a half year after its occurrence. Thus, the ENSO effect on benthic organisms should not be treated like a “physical action‐reaction” but rather as an ecological relationship with lag‐periods (“ecological inertia”) after its occurrence. On the other hand, one of the studied confluences was categorized as a “hydro‐geomorphic patch” along the river channel, resulting from shifts in hydraulic and sedimentological conditions, which are explained by local morphological features. This hydro‐geomorphic patch created a critical site of abrupt changes in ecological patterns, enhancing the biodiversity of the river system. However, this hydro‐geomorphic patch was not detected in another anabranch confluence, where the benthic assemblage was comparable with that recorded in straight sections. Accordingly, we concluded that the mere presence of an anabranch confluence is not sufficient reason to assume enhancing local habitat heterogeneity or biodiversity.

The overwhelming majority of research conducted to date on plastic pollution (all size fractions) has focused on marine ecosystems. In comparison, only a few studies provide evidence for the presence of plastic debris in freshwater environments. However, owing to the numerous differences between freshwater studies (including studied species and habitats, geographical locations, social and economic contexts, the type of data obtained and also the broad range of purposes), they show only fragments of the overall picture of freshwater plastic pollution. This highlights the lack of a holistic vision and evidences several knowledge gaps and data biases. Through a bibliometric analysis we identified such knowledge gaps, inconsistencies and survey trends of plastic pollution research within freshwater ecosystems. We conclude that there is a continued need to increase the field-data bases about plastics (all size fractions) in freshwater environments. This is particularly important to estimate river plastic emissions to the world's oceans. Accordingly, data about macroplastics from most polluted and larger rivers are very scarce, although macroplastics represent a huge input in terms of plastics weight. In addition, submerged macroplastics may play an important role in transporting mismanaged plastic waste, however almost no studies exist. Although many of the most plastic polluted rivers are in Asia, only 14% of the reviewed studies were carried out in this continent (even though the major inland fisheries of the world are located in Asia's rivers). The potential damage caused by macroplastics on a wide range of freshwater fauna is as yet undetermined, even though negative impacts have been well documented in similar marine species. We also noted a clear supremacy of microplastic studies over macroplastic ones, even though there is no reason to assume that freshwater ecosystems remain unaffected by macro-debris. Finally, we recommend focusing monitoring efforts in most polluted rivers worldwide, but particularly in countries with rapid economic development and poor waste management.

The regulation of anthropogenic pollution inputs into large rivers is an important aspect of ecological resilience of aquatic systems and river pollution management. The current study examined the relationship between contamination loads, hydrological and morphological patterns and the distribution of macroinvertebrates and epipelic diatoms in the middle Paraná River system to form part of the development of a pollution monitoring frame work. Seven sampling sites were selected over three main river areas predominantly impacted by sewage effluent and agriculture activities. The sampling areas were the Paraná, Colastiné and Las Conchas rivers. In order to prevent dilution of pollutants and macroinvertebrate drift, sampling was performed during the base flow period of 2015 to determine pollution contaminated stretches of the river system. Results indicated that metals have been accumulated in river bottom sediments as a consequence of anthropogenic land use activities. Macroinvertebrate and epipelic diatom assemblages as bioindicators of anthropogenic pollution were evident downstream of urban sewage effluent discharges causing higher concentrations of Cr, As and Ni than the permitted threshold levels for bottom sediment.

Fish assemblages recorded from August 2010 to July 2013 in two lotic and lentic environments of the Middle Paraná River floodplain were studied in the light of flood and flow pulse variations. Three flood pulses occurred during the period of study, each with a different magnitude, duration and timing. Instead four flow pulses were recorded during this period. The varied hydrological conditions had an influence on the ichthyofauna. The fish species richness in both lentic and lotic habitat was negatively correlated with the maximum water level and fish assemblages were spatially and temporally structured according to their different reproductive strategies. Long- and short-distance migratory species were dominant after the flood pulse of the highest intensity and longest duration, whereas sedentary fish and internal fertilisation prevailed during flow pulses and lower flood pulses. Fish assemblage similarity was generally low between habitats during flood and flow pulses, but increased after those events depending on their magnitude, duration and timing. Apparently, flow pulses would also function like floods, as mechanisms of spatio-temporal structuring of fish assemblages.

With the objective of finding fluctuations on fish body condition in the Middle Paraná River floodplain in different hydrological scenarios, this attribute was analyzed in several trophic groups of a secondary floodplain channel and its associated lakes between 2010 and 2012. Standardized residuals generated by length-weight regressions were calculated for each species and the relative weight (Wr) of the most abundant species per group was examined. A two-way factorial ANOVA was carried out (factors: hydrology and habitats) to evaluate the existence of significant spatial-temporal differences by groups and species. Results showed that body condition in detritivorous, herbivorous and omnivorous species fluctuated significantly depending on hydrology and the environment. Optimal body condition was recorded after the largest flood pulse in most species. Body condition decreased during the low-water period and after two disconnection periods, whereas during the second flood pulse it increased in detritivores, herbivores and omnivores. No floods occurred thereafter, but two flow pulses were registered, and body condition increased under these hydrologic scenarios, with similar or higher values to those recorded after the largest pulse. These results indicate that flow pulses, which are supplementary to flood pulses, may have a positive effect on fish body condition.
