“…In a recent study [59], changes in levels of carbonyl proteins and activity of AChE and GSH in tissues of fish (Rhamdia quelen) experimentally placed in three sites of Vacacaí River reinforced the effects of pesticide pollution on the Pampa's aquatic fauna. The fungicide tebuconazole (0.30 µg L −1 ) and the herbicides bentazon (0.77-1.80 µg L −1 ), clomazone (0.31-0.41 µg L −1 ), clorimuron (<LOQ), and quin-clorac (0.40-0.45 µg L −1 ) were detected in water, and fish exposed to the sites closest to agricultural areas showed higher levels of biochemical changes compared to a control [59].…”

“…Moreover, changes in levels of lipid peroxidation and acetylcholinesterase (AChE), glutathione S-transferase (GST), and catalase (CAT) enzymes were reported in a study performed with D. rerio embryos exposed to water from the Vacacaí River contaminated with pesticides (ten fungicides, eight herbicides, and six insecticides were detected in the water) [58].

The Brazilian Pampa biome covers half of Rio Grande do Sul state, in the extreme south of Brazil, creating an ecotone zone with the Atlantic Forest and bordering Pampa’s territory belonging to Uruguay and Argentina. Pampa is a non-forest biome mainly composed of grasslands and mosaics of grassland-forest vegetation. This biome shows significant animal and plant diversity, contributing to the maintenance of important ecosystem services, including CO2 capture, pollination, and water cycle regulation. However, forestry plantations, inappropriate cattle ranching, mining activities, unplanned urbanization, and the cultivation of monocultures (soy, rice, tobacco, and other cash crops) significantly threaten the conservation of the Pampa biome. A major problem observed in the Pampa, due to the great connection of this biome with agricultural areas, is pesticide pollution, which significantly affects the health of humans and animals that occupy the region. A robust body of evidence indicates that aquatic and terrestrial ecosystems in the Brazilian Pampa are extensively contaminated with pesticides, as indicated by studies involving animal biomarkers and pesticide analyses performed on water and soil samples. Human studies also suggest that pesticides affect different body systems, facilitating the onset of various chronic diseases. Brazil’s conservation actions and policies have a special focus on forest ecosystems, neglecting non-forest biomes and thus aggravating the problems related to Pampa’s conservation. In this article, we discuss some problems caused by pesticide pollution in the Brazilian Pampa, drawing attention to the need for intensification of policies focused on the promotion of human and environmental health. Finally, we suggest the bioecological bioeconomy as an alternative for Rio Grande do Sul to progress its economic development but with less dependency on detrimental activities to the Pampa biome.

“…Among the criteria for selecting these species as bioindicators are well‐known ecological characteristics, such as long life cycle, easy identification, and medium/large size (Freitas & Siqueira‐Souza, 2009). Furthermore, R. quelen has been used as an evaluation tool in various environmental assessments, providing insights into water contaminants (Becker et al, 2009; Ghisi et al, 2011; Marins et al, 2021; Severo et al, 2023). T. striatulus has served as a biodiversity bioindicator for insects and is also associated with the types of exogenous food in water (dos Santos et al, 2009).…”

The study of diet is one of the mechanisms by which competition for resources between species that cohabit in the same ecosystem can be inferred. Therefore, the relationships of the indices that measure specialization in the diet of fish species are necessary to characterize the nutritional quality of these populations and the ecosystem's environmental health. Three species of catfish were selected: one invasive (Clarias gariepinus) and two natives (Trachelyopterus striatulus and Rhamdia quelen), with similar distribution along the Guapi‐Macacu River, in the Guapimirim Protection Area (Rio de Janeiro). Fifty‐nine catfish of the three species were collected in total, along 32 collection points in the Guapi‐Macacu River in two periods (dry and rainy) in 2018. Non‐parametric statistics showed the partition of resources between species and the influence of abiotic factors (temperature, pH, transparency, and dissolved oxygen) contributing to the selection of available resources in the environment. Diet‐related indices—repletion index (RI), condition factor (K), niche width, and trophic position (TP) of the specimens collected—contributed to measuring the nutritional status of each of these catfish species, showing that R. quelen has a relationship between RI and K, tending to absorb and metabolize nutrients faster than other species. In addition, the invasive species occupies a wide range of TPs compared to native species, confirming its feeding plasticity. On the contrary, T. striatulus needs large amounts of terrestrial insects to maintain its poor condition factor. Also, the RI showed direct influences of abiotic variables, with the temperature being the most prominent. Our results suggest that the invasive species can benefit from this environment that shows signs of environmental degradation.
