Abstract
Neotropical Ichthyology promotes the Special Issue (SI) “Human impacts and the loss of Neotropical freshwater fish diversity” with the purpose of publishing relevant scientific articles on the current biodiversity crisis and the loss of Neotropical freshwater fishes in the Anthropocene. The SI is composed of 22 publications, being two review articles and 20 original articles. A total of 107 researchers contributed to these papers, involving 44 institutions based in Brazil and six other countries. Published articles investigated main anthropic activities and their impacts on fish diversity, with special focus on river regulation, mining, land use changes, aquaculture, and fisheries. Studies provided evidence about the loss of fish diversity in the Neotropics, including fish kill events, demographic changes, contamination, changes in assemblage structure, loss of taxonomic and functional diversity, besides the degradation of ecosystem functions and services, and the lack of effective protection and conservation. Studies were conducted in rivers, streams, lakes, and reservoirs from different Neotropical systems. The studies published in this SI represent a relevant sample of the current worrisome situation of freshwater fishes in the Neotropical region and call for urgent revision in environmental policies, management and conservation initiatives, and socioeconomic priorities.

Introduction
The Neotropical region houses a spectacular fish diversity, unparalleled to any other biogeographic region on the planet. More than 6,000 freshwater species have been formally described and cataloged (Albert et al., 2020), constituting a unique biological heritage. This number is certainly incomplete, as estimates indicate the existence of 8,000 to 9,000 species only in South America (Reis et al., 2016). Fish diversity is demonstrated in multiple dimensions, with a fabulous variety of morphologies, behaviors, life histories, historical/evolutionary relationships, and ecosystem functions (Winemiller, 1989; Reis et al., 2003; Toussaint et al., 2016; Vitule et al., 2017). The biogeography of the Neotropics is also remarkable, as its geological history provided a physiographic matrix of high environmental heterogeneity, allowing the evolution of a rich diversity of freshwater fishes, creating complex distribution patterns and endemism at different spatial scales (e.g., Dagosta, de Pinna, 2019). The presence of large river systems and thousands of small independent drainages, with important geological events (e.g., Andes uplift and evolution of separate shields), made the Neotropical region a vivid laboratory of evolution and diversification of unique biological lineages (Dagosta, de Pinna, 2017; Albert et al., 2018, 2020).
The Anthropocene, however, brought enormous challenges to the conservation of Earth’s biodiversity. Particularly, Neotropical freshwater fishes (NFF) have been subjected to increasing, multiple and synergistic anthropogenic impacts (Barletta et al., 2010; Costa, Barletta, 2016; Reis et al., 2016; Torremorell et al., 2021). Hundreds of studies have reported the erosion of NFF diversity, depicted as changes in multiple organization levels (i.e., from organisms to communities), including changes in diversity patterns, demography, community structure, species richness or even extinction (e.g., Pelicice et al., 2017 and references). The expansion of human activities, particularly agriculture, construction of dams, aquaculture, urbanization, mining, and fishing, has transformed the structure, dynamics, history, and functioning of inland aquatic ecosystems. These activities have induced severe changes to fluvial hydrology, geomorphology, and connectivity, caused significant losses of riparian and aquatic habitats, changed land cover and carbon fluxes, favored invasive species, caused contamination by urban and agricultural pollutants, overfishing, among other disturbances (e.g., Araújo et al., 2009; Agostinho et al., 2016; Tregidgo et al., 2017; Brejão et al., 2018; Garcia et al., 2018; Loures, Pompeu, 2018; Pelicice et al., 2018; Moi et al., 2021). Currently, all aquatic ecoregions in the Neotropics are subjected to human stressors, and some drainages have been highly degraded (e.g., Doce, Paraíba do Sul, São Francisco, upper Paraná, and Tocantins-Araguaia basins). Environmental degradation has reached regions previously considered pristine, which concentrate high diversity and endemism, such as the Amazon basin and the Andes (Winemiller et al., 2016; Anderson et al., 2018; Duponchelle et al., 2021; Pelicice, Castello, 2021). This scenario shows that the current biodiversity crisis hovers over NFF; a process with planetary consequences.
Given the current scenario and the need to address this important environmental issue, Neotropical Ichthyology promoted this Special Issue (SI) “Human impacts and the loss of Neotropical freshwater fish diversity”, with the purpose of publishing relevant scientific articles on the current biodiversity crisis and the loss of NFF. Several experts were invited to contribute to this issue, which resulted in the publication of 22 papers. These publications investigate different human stressors and impacts and show compelling evidence on the loss of fish diversity, epitomizing the current biodiversity crisis in the Neotropical region.
The Special Issue
The SI is composed of 22 publications, being two review articles and 20 original articles. A total of 107 researchers contributed to these papers, 69.2% from Brazil and 30.8% from other countries. It involved 44 institutions (i.e., universities, research institutes, government agencies) based in Brazil (58.7%) and six other countries (41.3%), i.e., Argentina, Colombia, Czech Republic, Guyana, United Kingdom, and United States of America. Most authors are male; however, considering the first author of each publication, 54.5% are women (Fig. 1). Eight editors of Neotropical Ichthyology organized the SI and handled the submitted manuscripts.
Published articles investigated main anthropic activities and their impacts on fish diversity, e.g., dam construction, mining, land use change, aquaculture, and fisheries (Tab. 1). Studies provided evidence about the loss of fish diversity, including fish kill events, demographic changes, contamination, changes in the assemblage structure, loss of taxonomic and functional diversity, besides the degradation of ecosystem functions and services, and the lack of effective protection and conservation (Tab. 1). Studies were conducted in rivers, streams, lakes, and reservoirs from different Neotropical systems, e.g., Uruguay, Paraná, Paraíba do Sul, Doce, São Francisco, Purus, Madeira, Essequibo, and Magdalena rivers, among others (Fig. 2).

The review articles published in this SI address original themes with high significance for the Neotropical region. Agostinho et al. (2021) examine the role of anoxia and gas supersaturation inducing fish mortality in areas affected by dams, exploring associated mechanisms and the occurrence of die-off events in different Neotropical systems. Mass mortality events have been recurrent in the region (Agostinho et al., 2007; Loures, Godinho, 2016), but this topic had not been investigated accordingly, sometimes treated in secrecy or even omitted. The second review addresses multiple impacts emerging from mining activities (Azevedo-Santos et al., 2021), including routine contamination by oils, metals, and other substances, besides the effects of concurrent deforestation, silting and road construction; this review also addresses large-scale degradation caused by the failure of tailings dams in southeastern Brazil.

Several research articles of the SI complement these reviews, investigating impacts caused by hydroelectric dams and mining activities. Some studies show how hydrological alterations, losing connectivity, and habitat degradation impact fish diversity and ecological relationships in the Uruguay (de Bem et al., 2021), Paraná (Ferraz et al., 2021), São Francisco (D’avilla et al., 2021), Madeira (Lonardoni et al., 2021), and Magdalena River basins (Moreno-Arias et al., 2021). The erosion of fish diversity included the loss of migratory and commercial species, especially in areas affected by cascades of dams — confirming previous investigations (e.g., Petesse, Petrere Jr., 2012; Agostinho et al., 2016; Loures, Pompeu, 2018; Pelicice et al., 2018; Santos et al., 2018; Ganassin et al., 2021). Concerning mining activities, Montaña et al. (2021) provide evidence of mercury contamination in fish captured near gold mining zones in the Essequibo River basin, Guyana. Predatory fish, regularly consumed by local communities, had the highest pollution burden, pointing to a public health risk. Studies on mining impacts are scarce and rarely assess ecosystem effects and losing fish diversity (e.g., Azevedo-Santos et al., 2016); the two studies published in the SI (Azevedo-Santos et al., 2021; Montaña et al., 2021) are clear about negative effects and emphasize the need for more research on the subject.
A series of articles provide evidence that changes in land cover impact NFF in streams, complementing many other studies published in the last decade (e.g., Casatti et al., 2015; Benejam et al., 2016; Dala-Corte et al., 2016; Teresa, Casatti, 2017; Leal et al., 2018; Brejão et al., 2018; Ilha et al., 2019). Overall, studies included in the SI reported changes in assemblage structure and loss of taxonomic and functional diversity associated with deforestation, urbanization, changes in hydrology, and the degradation of instream habitats. In the upper Paraná River basin, Miiller et al. (2021) report changes in functional diversity along rural and urban gradients, while Alvarenga et al. (2021) investigate mechanisms and indicate multiple pathways of impacts emerging from changes in the landscape. Concerning urbanization, Ortega et al. (2021) show that non-native species dominate urban streams in the Cuiabá River basin, where the proportion of impervious surfaces significantly affected species richness and beta diversity. Two studies were conducted in the Amazon Basin. In the Madeira River basin, Brejão et al. (2021) show that different deforestation regimes affect beta diversity patterns across streams, showing that the assemblage composition is affected by changes in land use; in the Xingu River basin, Freitas et al. (2021) report significant alteration in natural stream conditions and functional diversity in streams affected by deforestation. Finally, Pott et al. (2021) investigate the effects of land use on the distribution of body sizes in fish assemblages in coastal streams of the Brazilian Pampa, indicating that effects depend on the spatial scale and functional group considered. Results emerging from these studies are clear about the effects of land use on diversity patterns, but they also reinforce the difficulty of making broad generalizations, since the response of NFF apparently depends on many factors, such as the local biota, biome, intensity and history of disturbances, spatial and temporal scales, among other drivers.
Three studies investigate the impacts of invasive species on NFF, confirming the role of aquaculture and sport fishing as main vectors of non-native fishes. Magalhães et al. (2021) investigate streams crossing the largest ornamental aquaculture center in Brazil (Muriaé, in Paraíba do Sul River basin), and show how multiple fish escapes, involving dozens of non-native species, affect the composition of local assemblages and induce biotic differentiation patterns. The case of Muriaé is one of the most emblematic examples of biological invasions involving the mass introduction of fish originated from multiple ecoregions of the planet (Magalhães, Jacobi, 2013; Magalhães et al., 2019). Other studies investigate the effects of non-native predators, complementing previous studies (e.g., Latini, Petrere Jr., 2004; Pelicice, Agostinho, 2009). In the Doce River basin, Souza et al. (2021) demonstrate that the invasion of several predatory fish eroded the taxonomic and functional diversity of NFF in natural lakes, including the extirpation of seven species. In Rosana reservoir, upper Paraná River basin, Leal et al. (2021) use an innovative approach to investigate how the invasion of Cichla kelberi Kullander & Ferreira, 2006 relates to the loss of ecosystem functions generated by fish populations. This topic remains poorly understood, and this study adds to previous works showing the great complexity associated with species invasion and losing ecosystem multi-functionality (e.g., Moi et al., 2021).
Two studies investigate the effects of fishing activities on fish populations, an issue poorly investigated in the Neotropical region. Scarabotti et al. (2021) analyze historical catches and population trends in the La Plata basin, covering different sectors of the basin. Results reveal different temporal trends among species and locations, with declining trends in the lower reaches of the basin, particularly for large migratory fish. Overfishing, and environmental degradation were identified as main drivers inducing demographic changes. In the Amazon basin, Tregidgo et al. (2021) examine the catch composition along the Purus River, pointing to strong selectivity induced by urban markets. The study shows that commercial fishing supplying large urban centers (e.g., Manaus) targets a few species, when compared to subsistence fishing carried out in remote localities. This fishery dynamics induces strong pressure on a few stocks, especially large species with greater commercial value [e.g., Arapaima gigas (Schinz, 1822), Colossoma macropomum (Cuvier, 1816), and Pseudoplatystoma punctifer (Castelnau, 1855)]. The effects of overfishing are difficult to quantify, requiring long time-series data and the measurement of associated and synergistic drivers. Therefore, the two studies published in the SI are highly valuable as they provide robust evidence of overfishing in large Neotropical rivers, especially upon large migratory fish historically exploited and subjected to multiple impacts.
Finally, three studies evaluate multiple threats and the conservation status of NFF. Bichuette, Gallão (2021) show major threats affecting fish diversity in caves and other subterranean ecosystems in Brazil, a fauna characterized by high endemism and vulnerability. Multiple stressors have affected these fishes, especially physical changes in the habitat, resource restrictions, and geo-hydrological changes. Oliveira et al. (2021) demonstrate that protected areas in the Paraná-Paraguay basin are not efficient in protecting fish diversity (taxonomic, functional, and phylogenetic), as the overlap between protected areas and more diverse sites is lower than 1.5%; protection will be even lower in projected climate change scenarios. Finally, Tagliacollo et al. (2021) assessed the extinction risk for over 5,300 species of NFF, based on criteria established by the IUCN. The authors listed 1,093 threatened or potentially threatened species (ca. 18% of all NFF), expanding the official IUCN list that currently lists 422 fish species. The risk is greater for species with restricted geographic distribution that inhabit upland areas and have been described recently. These results agree with other studies published in the SI and epitomize the growing threats and the critical conservation status of many NFF.
Neotropical Fishes in the Anthropocene
The SI gathered studies on human impacts and the loss of freshwater fish diversity in the Neotropical region, complementing previous studies published by Neotropical Ichthyology (e.g., Pelicice et al., 2018; Ilha et al., 2019; Van Damme et al., 2019; Tonella et al., 2019; Brejão et al., 2020) and other scientific journals (e.g., Daga et al., 2015; Correa et al., 2015; Anderson et al., 2018; Brejão et al., 2018; Loures, Pompeu, 2018; Bezerra et al., 2019; Herrera et al., 2020; Dias et al., 2021). The topic has attracted growing attention from the scientific community, as aquatic ecosystems have been progressively degraded, impaired, and lost (Strayer, Dudgeon, 2010). The articles published in the SI show that ichthyologists in the Neotropical region have been conscious of this troubling scenario.
There is a general pattern of environmental degradation in the Neotropical region and elsewhere, as human stressors tend to be the same: river damming, changes in land use (agriculture and urbanization), aquaculture, mining, and overfishing (Fig. 3). There are other drivers (Pelicice et al., 2017; Santana et al., 2021), but the articles published in the SI reinforce the idea that human development has subjected NFF to similar stressors, which involve changes in natural flow regimes, habitat fragmentation and loss, environmental degradation, and biological invasion. Some drivers have received more research effort (e.g., large hydroelectric dams), which allowed the development of robust knowledge and a predictive basis (Agostinho et al., 2016). Other activities, however, remain poorly investigated (e.g., mining), or need further examination and detailing (e.g., changes in land use, biological invasion) – pointing in the direction for future research. Ichthyologists must continue to focus on the topic, to quantify the magnitude of each impact, identify main stressors, test, and propose causal links, build a framework that allows wide generalization and predictions, and propose management and restoration actions.
FIGURE 3 | Main human stressors associated with the loss of Neotropical freshwater fishes, investigated by studies published in this Special Issue of Neotropical Ichthyology.
Environmental degradation and the decline of fish diversity is a global process, affecting unique ecosystems and drainages on the planet (Toussaint et al., 2018; Grill et al., 2019; Deinet et al., 2020). This phenomenon has been reported consistently since the second half of the 20th century, but it has sped up with the expansion of human activities in the last ca. 50 years. In the Neotropical region, losing fish diversity has been widely reported (e.g., Pelicice et al., 2017 and references). Losing diversity entails changes in different levels of biological organization, from genes to ecosystems, implying changes in the genetic structure, biochemistry, physiology, demography, assemblage structure and biogeography, besides the extinction of lineages. Concerning NFF, diversity losses are a matter of great concern, as the Neotropical region holds the greatest fish biodiversity on the planet (Toussaint et al., 2016; Vitule et al., 2017; Albert et al., 2020). Losing NFF has effects on patterns and processes (i.e., evolutionary, ecological, ecosystem, economic) operating at multiple spatial scales. In fact, it has negatively affected fishery resources (e.g., Agostinho et al., 2007; Hoeinghaus et al., 2009; Hallwass et al., 2013; Van Damme et al., 2019) and the generation of important ecosystem functions (e.g., Taylor et al., 2006; Winemiller et al., 2006; Correa et al., 2015; Costa-Pereira, Galetti, 2015). Fish are key components of aquatic ecosystems, where they play essential functions and services (Holmlund, Hammer, 1999; Flecker et al., 2010), including fishing goods, assimilation and transfer of matter/energy, population control, or the dispersion of propagules. Therefore, losing NFF represents an important component of the current biodiversity crisis, which has triggered growing environmental, economic, social, and cultural implications, many of which are irreversible.
The conservation of NFF in the Anthropocene faces increasing challenges. Current human activities have induced large-scale environmental degradation, and new stressors are emerging (e.g., climate change, pandemics). Currently, the Brazilian Red List of Endangered Species includes 311 NFFs (ICMBio, 2018), but the number of imperiled species and populations is certainly underestimated (Pelicice et al., 2017; Santana et al., 2021; Tagliacollo et al., 2021). The current scenario is pessimistic, fueled by unsustainable policies, economic and social crisis, and pressure for short-term development based on high-impact activities (e.g., Dobrovolski et al., 2018; Pelicice, Castello, 2021). Nations in Latin America have a great responsibility to preserve NFF, which will require the revision of current economic and environmental policies. Priority actions, based on scientific information, should promote the preservation and restoration of freshwater ecosystems, to preserve natural flow regimes, connectivity, fluvial and riparian environments, and critical habitats. The establishment of protected rivers should be seriously considered (Azevedo-Santos et al., 2019), as well as the strict preservation of riparian areas (Dala-Corte et al., 2020). Such measures conflict with current development approaches, but the lack of effective conservation policies will deepen the biodiversity crisis and jeopardize future ecosystem services and human welfare. The studies published in this SI represent a relevant sample of the current situation of freshwater fishes in the Neotropical region and call for an urgent revision in environmental policies, management and conservation initiatives, and socioeconomic priorities.
