“…The estuarine regions in southern Brazil present a greater variety of habitats compared to adjacent coastal zones (Ramos and Vieira, 2001;Odebrecht et al, 2017). With regard to the TRE and AC complex, Garcia et al (2018b) shows that fish assemblages in continental systems are sustained by a greater number of autotrophic sources than in the adjacent marine systems.…”

“…They have also explained relationships between environmental variables, anthropic activities and especially natural phenomena (for example, El Niño events) in the Patos Lagoon estuarine region (Garcia and Vieira, 2001;Garcia et al, 2004Garcia et al, , 2012Vieira et al, 2010). These studies enhance the capacity to predict biodiversity responses to global change, specifically responses to both anthropogenic pressures and large-scale climatic events, and can lead to proposals for the conservation and sustainability of local areas (Odebrecht et al, 2017).…”

“…The southern coastal plain of Brazil, especially the Rio Grande do Sul state, is composed of several aquatic ecosystems, encompassing habitats of great biological importance (Ramos and Vieira, 2001;Odebrecht et al, 2017). The Tramandaí River estuary (TRE; 29 • S; estuarine area c.18.8 km²) is the second larger estuary after the Patos Lagoon estuary (32 • S; estuarine area c. 1,000 km²).…”

“…In some cases, long-term records are used as the basis for environmental quality or restoration program targets (Tonn et al, 1990). Long-term studies, such as the Brazilian Long Term Ecological Program (PELD) in the Patos Lagoon estuary, provide a unique perspective on the complex dynamics of organisms and ecosystems (Odebrecht et al, 2017). Longterm studies have provided answers concerning spatial and temporal patterns of fish abundance and diversity.…”

Long-Term Spatiotemporal Variation in the Juvenile Fish Assemblage of the Tramandaí River Estuary (29°S) and Adjacent Coast in Southern Brazil

We evaluated connectivity, resiliency, and spatiotemporal variation in fish associations between the Tramandal River estuary (TRE) and the adjacent coast (AC). This was based on intermittent and seasonal data covering a discontinuous 21-year period (1995 to 2016) obtained using a standard beach seine with replicate samples collected at several points. In the TRE (405 samples; 42,987 individuals) 55 species were captured. In the AC (297 samples; 54,295 individuals) 41 species were captured. After data standardization the expected richness of the TRE [E(S) = 18.2] was significantly greater (P < 0.05) than that of the AC [E(S) = 14.4]. The fish association structure and distribution patterns in TRE and AC were dynamic and interconnected but quite different in terms of species composition, especially due to the influence of local salinity. The TRE association was richer in a number of species but numerically dominated by marine estuarine-dependent juveniles. The AC association was represented by a few typical marine species in addition to a couple of estuarine-related transient species who used the surf-zone as a passageway to enter the estuary. Even if there was a higher percentage of common species reported (30 out of 66), the monthly average Jaccard index of similarity (I J = 28%) and the monthly average percent similarity index (I PS = 30%) were low, suggesting that the shallow water functional connectivity between AC and TRE was represented by few species that occur equally in abundance in both environments. Trachinotus marginatus and Mugil liza numerically dominated in the AC and M. liza, Mugil curema, and Atherinella brasiliensis at TRE. Juvenile M liza and M curema added up to >70% of the total individuals sampled in both environments. General linearized models (GLM) revealed that diversity was not influenced by interannual variations, evidencing that juvenile fish assemblage of AC and TRE are resilient through the years. Standardized beach samples are able to reveal long-term fluctuation in shallow estuarine fish communities but without an apparent loss in species composition, richness, and relative total abundance. The only observed interdecadal trend was the reduction in abundance of juvenile M. liza that seemed to parallel the reduction in abundance of the adult fishing stocks in southern Brazil.

“…Despite the important global initiatives (e.g. International Long-Term Ecological Research) long-term, integrated, ecosystem-level monitoring efforts are still scarce for most coastal and marine ecosystems (Kennish and Paerl, 2010;Duffy et al, 2013;Vihervaara et at., 2013;Muelbert et al, 2019), particularly in Southern Hemisphere (Odebrecht et al, 2017). The scarcity of temporal data 50 series from coastal ecosystems hampers the assessment of the impacts and undermines our ability to respond effectively to these threats (Turra and Denadai, 2016).…”

Abstract. Estuaries are among the most productive aquatic ecosystems and provide important ecological and economic services in coastal areas. However, estuarine systems have been threatened worldwide by natural and anthropogenic impacts acting on local, regional and global scales. Long-term ecological studies contribute to the understanding and management of estuarine functioning, and provide the baseline information for detection changes and modeling of predictive scenarios. Here, we describe long-term data on the biodiversity and physico-chemical parameters obtained from 1993 to 2016 for the Patos Lagoon estuary and adjacent marine coast, in southern Brazil. We report eight datasets containing 6,972 sampling events with the occurrence and abundance records of 275 species (Kingdoms: Bacteria, Protozoa, Chromista, Plantae and Animalia) of functional groups plankton, benthos and nekton. Datasets also include 22,190 abiotic records. Database is published in the Global Biodiversity Information Facility (GBIF) repository (see Data availability in Sect 3). The present compendium represents one of the most comprehensive and longest datasets from primary producers to top predators in an estuarine-coastal system in South America and their availability will be an important contribution to the understanding and predictability of estuarine dynamics around the world.
