“…A saúde e o adoecimento das populações, advém por diversos fatores: sociais, políticos, econômicos, ambientais, psicológicos e físico, esses fatores aos se combinarem com falta de infraestrutura, saneamento básico, lazer, educação, alimento digno livre de agrotóxicos ou qualquer outro resíduo químico, podem causar um serie de prejuízos a saúde dos indivíduos (RATTNER, 2009;CARVALHO, 2013;LIMA;JÚNIOR;LUNA, 2018). A sustentabilidade vem justamente apresentar em seus pilares objetivos com o propósito de mudar esse tipo de cenário, que busque uma real transformação e preservação do meio ambiente, como também, uma cuidar do ser humano, gerar dignidade, igualdade entre raças e gêneros, alimentação saudável, educação e saúde de qualidade, enfim a criação de programas que forneçam subsídios para que os povos se desenvolvam e convivam em harmonia consigo e com as demais formas de vida que compõem a natureza (RATTNER, 2009;CARVALHO, 2013;LIMA;JÚNIOR;LUNA, 2018).…”

O estudo abordou a complexa relação entre a crise ambiental e a saúde, enfatizando o papel dos profissionais de saúde na promoção da sustentabilidade. Através de uma revisão abrangente da literatura, foram identificados vários estudos que destacam a interconexão entre o meio ambiente e a saúde humana. Embora tenham sido observados progressos, a pesquisa ressaltou uma lacuna significativa de publicações nessa área, sublinhando a necessidade urgente de maior engajamento e estudos para abordar essa questão crucial. Os resultados revelaram uma diversidade de abordagens, incluindo revisões bibliográficas, estudos reflexivos e pesquisas de campo, demonstrando a amplitude e relevância do tema. Ficou evidente que os profissionais de saúde desempenham um papel vital na incorporação de práticas sustentáveis em suas atividades diárias, desde a redução de resíduos até a promoção de hábitos saudáveis e ecológicos. Portanto, é imperativo que os currículos de formação dos profissionais de saúde integrem princípios de sustentabilidade e que estratégias práticas sejam implementadas para incentivar a adoção dessas práticas. A conscientização sobre a relação intrínseca entre a saúde humana e a saúde do planeta é essencial para construir um futuro mais resiliente e equilibrado. Através dessa abordagem, os profissionais de saúde podem se tornar agentes de mudança, contribuindo para a construção de uma sociedade mais saudável, justa e em harmonia com o meio ambiente, buscando garantir um legado sustentável para as gerações futuras.

“…The number of studies increased between 1959 and 2020, but with a weak trend when controlled by the growth of the world scientific production, indicating modest growth in this specific field. This trend was reported in a previous study (Cruz et al ., 2016) and in several studies that investigated other topics, including fish (Junqueira et al ., 2020; Lima et al ., 2021; Pereira et al ., 2020). A series of logistical and methodological obstacles may explain this weak trend, with emphasis on field and laboratory demands, complex sampling logistics, and eggs and larvae identification (Ahlstrom & Moser, 1976).…”

Syntheses of knowledge are important to reveal trends, biases and gaps in the scientific literature, indicating main data shortfalls and research needs. In this regard, the authors conducted a broad systematic review on the literature about freshwater fish eggs and larvae to investigate (a) temporal trends in the global scientific production, (b) the scope and habitat types, (c) the spatial distribution of studies, (d) the fish species contemplated and their respective conservation status and (e) the factors associated with the spatial distribution of studies. They analysed 654 studies published between 1950 and 2020. The number of studies has increased over time, but with a weak trend. Most studies investigated basic questions about biology and ecology and were carried out chiefly in rivers and lakes. These studies covered 95 freshwater ecoregions (22.3% of all ecoregions) and recorded 871 fish species (4.8% of all freshwater fish currently described). Most species were assessed by the IUCN and classified into six threat categories, but approximately 35% were not evaluated. The main drivers affecting the spatial distribution of studies were ecoregion area, road density, river volume and the number of hydroelectric plants. Results point to significant biases and gaps in the global scientific literature on fish eggs and larvae, especially associated with habitat type, spatial distribution and target species, emphasizing the need to address specific topics. Such biases and gaps indicate the existence of important data shortfalls, which compromise management and conservation planning, as information on fish eggs and larvae is basic and critical for the assessment of fish recruitment and population dynamics.

“…Even after two decades after the first studies with stream fish in the studied region, we still have a long way to know the actual diversity of stream fish in these basins. Although the number of researchers working with stream fish has increased, this advance is based less on taxonomic research than on other stream fish research (Junqueira et al 2020, Lima 2021.…”

Streams fish from Upper Araguaia and Middle Rio da Mortes basin, Brazil: generating subsidies for preservation and conservation of this critical natural resource

et al. 2021

The Araguaia River basin has the highest fish biodiversity within the Cerrado biome (Brazilian savannah), with many endemic and threatened species by human activities. Despite growing efforts to catalog Neotropical freshwater fish biodiversity, many regions are still undersampled. Our objective is to complement the information about stream fish in two hydrographic basins in the Cerrado. We sampled 72 streams with 50 m stretch in the Upper Araguaia (n = 32) and Middle Rio das Mortes (n = 40) basins. We collected 14,887 individuals distributed in 137 species, 81 genera, 30 families, and six orders. Characidae, Loricariidae, and Cichlidae were the families richer in species. We found a high diversity of rare fish species in the streams sampled, ca. 71.5% of the species had at least five individuals collected, and 18 species had only one collected specimen. The most frequent species were Astyanax cf. goyacensis, Knodus cf. breviceps, and Characidium cf. zebra. Both basins shared around 43% of the species. We caught 76 species in Upper Araguaia and 120 species in Middle Rio das Mortes. Seventeen exclusive fish species occurred in Upper Araguaia, whereas 61 were found in the Middle Rio das Mortes basin. Our analysis showed lower diversity of fish in Upper Araguaia than in the Middle Rio das Mortes basin. Considering the exclusive fish species of both basins, the human threats in those regions, and the few existent protected areas, we need a better look at the aquatic biodiversity conservation of this ecosystem.
