“…Juveniles of C. guatucupa occur in the estuary and the adults enter the system after marine spawning to feed (Lopez Cazorla, ; Sardiña & Lopez Cazorla, ), and both adults and juveniles of the widespread P. orbignyanus occur throughout the estuary. The marine estuarine‐opportunist, Jenyns' sprat Ramnogaster arcuata (Jenyns 1842) is zooplanktivorous and abundant in Bahía Blanca where it forms an important food item for the above‐described species (Lopez Cazorla et al , ).…”

Estuarine fish research in South America began in the early 20th Century, but it is only within the last 40 years that detailed studies have been undertaken. This review firstly summarizes research results from South American estuaries by geographic area, starting with the temperate south-east, then the temperate-sub-tropical transition zone in Brazil, then the semi-arid and tropical estuaries of north and north-east Brazil including the Amazon complex, then the north and Caribbean coasts and finally down the Pacific coast of the continent. They include almost all types of estuarine systems, from large open systems (e.g. the temperate Rio de La Plata and tropical Amazon) to extensive coastal lakes (e.g. the temperate Patos Lagoon and tropical Cienega Grande de Santa Marta). They encompass a broad range of climatic and vegetation types, from saltmarsh systems in the south-east and fjords in the south-west to both arid and humid tropical systems, dominated by mangroves in the north. Their tidal regimes range from microtidal (e.g. Mar Chiquita, Argentina) through mesotidal (e.g. Goiana, Brazil) to macrotidal in the Amazon complex where they can exceed 7 m. The review uses where possible the recent standardization of estuarine fish categories and guilds, but the ways that fishes use tropical South American systems may necessitate further refinements of the categories and guilds, particularly in relation to freshwater fishes, notably the Siluriformes, which dominate many north and north-east South American systems. The extent to which South American studies contribute to discussions and paradigms of connectivity and estuarine dependence is summarized, but work on these topics has only just begun. The anthropogenic issue of pollution, particularly in relation to heavy metals and fishes and fisheries in estuaries is more advanced, but the possible effects of climate change have barely been addressed. Studies around conservation and management are briefly reviewed and the extent to which key factors are being addressed is examined. Although there have been major advances in knowledge of estuarine fishes in South America, information is patchy, with most data from relatively few systems in Argentina and Brazil.

“…For the Bahía Blanca Estuary (Figure S18), the reproductive aspects of Sympterygia acuta (Rajidae) (Díaz-Andrade et al, 2009) and the feeding ecology of R. arcuata (Lopez Cazorla et al, 2011) are described. In addition, the influence of biotic and environmental factors on seasonal patterns of juvenile fishes in Spartina alterniflora saltmarsh and a contiguous tidal flat in the Bahía Blanca Estuary was also evaluated (Valiñas et al, 2012).…”

Research on estuarine ecology in South America (SA) increased quali-quantitatively since the early 1980 in search of consistent recommendations for estuarine conservation. The most important ecological theory achieved is that the seasonal fluctuation of the salinity gradient creates an ecocline influenced by gradual changes between river-dominated to marine-like waters. Estuarine fish fauna adapts to these changeable abiotic characteristics, including the spatial, and seasonal bioavailability of dissolved oxygen and numerous pollutants. However, studies on the influence of the estuarine ecocline are still missing for key estuarine systems. This study provides an overview of fish ecology and anthropogenic impacts within estuarine systems of SA and discusses priorities for environmental conservation. Research on fish reached important conclusions regarding essential habitats and fish interaction with other biological and abiotic compartments over spatio-temporal settings, including conditions of severe anthropogenic impacts. These impacts are related to unplanned urban settlements, industrial estates, ports, damming of major rivers, dredging activities, and deforestation for extensive farming. Changes in estuarine morphology alter natural flows and lead to habitat losses, disrupting the ecocline and impairing fishes from moving among formerly connected habitats, especially earlier ontogenetic phases. In addition, industrial, urban, and farming activities often result in high loads of metals and persistent organic pollutants, organic enrichment and oxygen depletion. Moreover, plastic debris, a ubiquitous contaminant with sources on every human activity, including fishing, when fragmented into microplastics, become preferably concentrated in semi-enclosed environments, as estuaries. Metals, POPs and microplastics are actually asserted to be persistent. When in high concentrations, they become bioavailable to the estuarine trophic web through bioaccumulation, being biomagnified or biotransfered toward higher trophic level organisms, such as top predator fishes. Therefore, research on environmental quality and fish ecology must be based on robust sampling designs along the whole ecocline using long-term approaches. In addition, basic sanitation, co-management, an improved Barletta and Lima Ecology and Conservation of South American Estuaries licensing system and scientifically-based risk assessments/monitoring for all sorts of enterprise are also urgent. These conservation priorities need to be in place before human-driven changes surpass the ecosystem's capacity to produce resources and maintain services.

“…This omnivorous species cohabits with ciliates during most of the year whereas it may reach up to 90 % of total mesozooplankton abundance during the warm season, concurrent with the highest annual concentration of tintinnids (Hoffmeyer 2004). In turn, A. tonsa is one of the main food sources of planktivorous fish (López Cazorla et al 2011). The aim of this study is to quantify the interannual response of ciliates to environment drivers, with emphasis on wind patterns and water turbidity.…”

Highlights ► Planktonic ciliate's abundance decreased over the last 25 years in a shallow estuary. ► Decreasing cell abundance was linked to changes in wind dominant regimes and increased water turbidity. ► Tintinnids were more vulnerable to wind patterns and turbidity and lost synchrony with primary productivity. ► Interannual variability of the copepod Acartia tonsa followed the changes in ciliate community. ► Erosive processes in shallow estuaries impact on the interannual dynamics of ciliates and such effects can cascade-up to copepods.
