“…For example, studies carried out after dam failures have used a functional approach based on the assemblage taxa presence. The authors of [87] identified 12 species of fish most suitable for monitoring, while another study [88] used DNA metabarcoding to identify microbial communities affected by tailing remnants in the water column and sediment. In addition, there are studies focused on the bioaccumulation of metals at high rates in fish tissues [89,90] and in shrimp [91], showing that dam tailing effects continue to impact the Doce River and its estuary.…”

Biomonitoring for Watershed Protection from a Multiscale Land-Use Perspective

The types and intensification of land use in the watershed affect the living organisms in aquatic ecosystems differently; this impact will also vary according to temporal and spatial scales. Understanding these interactions is crucial in the design of biomonitoring programs to detect the effect of different pollutants in freshwater ecosystems and improve watershed management and conservation strategies. Therefore, this paper qualitatively reviews biomonitoring studies in freshwater ecosystems to evaluate the impact of different land use types on multiple scales in watersheds. The paper is organized into four sections. The first section presents biomonitoring in different freshwater systems (streams, rivers, lakes, and reservoirs). In the second section, we describe the biomonitoring characteristics of the main land use types. In the third section, we explain how spatial and temporal scales affect biomonitoring. Finally, in the fourth section, we focus on biomonitoring planning and future prediction and discuss how to design biomonitoring programs and how to use models and eDNA in biomonitoring. Our review will assist in decision-making regarding biomonitoring programs in watersheds and will guide future studies on the different bioindicators for various land use types in diverse ecosystems worldwide.

“…That is the case of the south of Brazilian east coast, an approximately 500 km shoreline spanning from the southern coast of Bahia to Cabo de São Tomé (northern coast of Rio de Janeiro) that contains several ocean beaches. The area also deserves particular attention because its biodiversity was dramatically affected by the collapse of the Fundão mine tailings dam (Condini et al 2021). This dam, located in the upper reaches of the Doce River catchment, collapsed on November 5, 2015, releasing 50 million m 3 of iron ore tailings into the Atlantic Ocean.…”

We characterized the surf-zone fish assemblage structure of an ocean beach on the central coast of Brazil (Guriri Beach, Espírito Santo) and assessed its diel variability. Like the entire Espírito Santo coast, Guriri Beach was also affected by ore tailings from the Fundão dam, which collapsed on November 5, 2015. Monthly samplings were carried out before the dam collapse along a year cycle (May 2013-April 2014), during the day and night in the neap tide, using a beach seine. A total of 2217 specimens were caught (1017 during the day and 1200 at night), distributed in 36 fish species and 20 families. Juveniles of the kingcroaker Menticirrhus spp., great pompano Trachinotus goodei, Florida pompano Trachinotus carolinus, littlescale threadfin Polydactylus oligodon, and Atlantic sabretooth anchovy Lycengraulis grossidens dominated the fish fauna, accounting for 84% of the total capture. The fish assemblage structure changed irregularly between day and night throughout the year. P. oligodon and Menticirrhus spp. were more abundant at night, whereas T. carolinus and L. grossidens were more abundant during the day. In most cases, no significant change was detected in fish abundance and richness between the day and night; when significant differences were detected, abundance and richness were higher at night. Our findings could support a monitoring program of the local surf-zone fish fauna and serve as before-impact data, allowing more accurate quantification of the ore tailings' impacts on the local fish biodiversity.
