“…The utility of a tool capable of identifying likely drivers of species declines using existing data, such as SDMs, becomes apparent when compiling a list of the multiple, synergistic stressors facing ecosystems. Anthropogenic impacts such as habitat loss, degradation, and fragmentation (Cushman, ; Perkin & Gido, ), climate change (Pearson & Dawson, ; Van der Putten et al ., ), changing land‐use patterns (Brewer et al ., ), competing demands for surface and groundwater (Mora et al ., ), and introductions of nonnative species (Westhoff et al ., ) are a few of the factors that interact to influence species abundance and distribution. Aquatic ecosystems are particularly susceptible to these multiple stressors as evidenced by the higher extinction rates of freshwater organisms compared to those seen in terrestrial counterparts (Ricciardi & Rasmussen, ; Revenga et al ., ; Jenkins, ).…”

Conservation efforts for threatened or endangered species are challenging because the multi-scale factors that relate to their decline or inhibit their recovery are often unknown. To further exacerbate matters, the perceptions associated with the mechanisms of species decline are often viewed myopically rather than across the entire species range. We used over 80 years of fish presence data collected from the Great Plains and associated ecoregions of the United States, to investigate the relative influence of changing environmental factors on the historic and current truncated distributions of the Arkansas River shiner Notropis girardi. Arkansas River shiner represent a threatened reproductive ecotype considered especially well adapted to the harsh environmental extremes of the Great Plains. Historic (n = 163 records) and current (n = 47 records) species distribution models were constructed using a vector-based approach in MaxEnt by splitting the available data at a time when Arkansas River shiner dramatically declined. Discharge and stream order were significant predictors in both models; however, the shape of the relationship between the predictors and species presence varied between time periods. Drift distance (river fragment length available for ichthyoplankton downstream drift before meeting a barrier) was a more important predictor in the current model and indicated river segments 375-780 km had the highest probability of species presence. Performance for the historic and current models was high (area under the curve; AUC > 0.95); however, forecasting and backcasting to alternative time periods suggested less predictive power. Our results identify fragments that could be considered refuges for endemic plains fish species and we highlight significant environmental factors (e.g., discharge) that could be manipulated to aid recovery.

“…In this sense, strategies should be based on the recovery and preservation of water bodies, especially of the sources, and the community can contribute in the protection and environmental preservation with the elaboration of self-sustaining development depending both on the attainment of scientific knowledge and on its publishing to the general public (Rogério, 2017), as human actions that interfere in natural cycles and in the availability of good quality water have compromised the sustainability of water resources (Tundisi, 2003). Sources have been the aim of many studies in Brazil (Ferreira et al, 2009;Soares et al, 2010;Koperski et al, 2011, Fry et al, 2012Mora et al, 2013;and Bomfim et al, 2015), but they are rare when one deals with rivers in the State of Maranhão and studies about the Rio Preto basin have not been found. In face of this reality, there is the need of plans for the revitalization of the Rio Preto, as well as its main tributary, the Rio Mocambo.…”

This work is the result of a project named "Lenghten Life", developed since 2010 in São Benedito do Rio Preto, Maranhão, Brazil, involving the Association of Children and Friends of São Benedito and the Association of Young People of Alto Rio Preto. It is a socio-environmental action which promotes the preservation and revitalization of Rio Preto and its main tributary, Rio Mocambo, important sources of water for the population. The operation occurs in three stages: 1) 7 groups of youths performed the river cleaning, quantifying collected garbage, the situation of the streams (tributaries) and environmental crimes. 2) teams sensitized river dwellers on the importance of preservation, pollution dangers and deforestation of the banks, and cataloged extinct species. 3) Plantation and cultivation of native species. The participants volunteered, the action was financed by residents' donation. In the first year, 132 volunteers participated, collecting 16,442 kilos of garbage and identifying 42 streams (21 "dead", 09 precarious and 12 good). In 2016, there were 131 participants, the removed garbage reduced to 5,400 kilos, 4 dead streams were revitalized, 5 improved and the others continued with good fluency. Deforestation and predatory fishing decreased. The Project showed efficiency in preserving Rio Preto through environmental education.

“…Essas estratégias devem ser pautadas na recuperação e preservação dos corpos hídricos, em especial das nascentes, pois, segundo Tundisi (2003), as ações do homem que interferem nos ciclos naturais e na disponibilidade de água de boa qualidade têm comprometido à sustentabilidade dos recursos hídricos. As nascentes têm sido objeto de estudo de vários pesquisadores no Brasil e em âmbito internacional desde o início do século XXI, como se observa em Soares et al (2010), Ferreira et al (2009), Menezes et al (2009), Ferreira et al (2011), Cabral da Silva et al (2011, Koperski et al (2011), Bruins et al (2012), Fry et al (2012), Mora et al (2013) entre outros.…”
