“…Alguns dos sinais clínicos mais frequentemente relatados por diversos autores incluem anemia, emagrecimento, incoordenação, mudança de comportamento, asas caídas, paralisia do trato digestivo, convulsões, amaurose, vocalizações, letargia e dispneia, podendo afetar a aptidão, capacidade de voo e a performance do animal (Ecke, et al, 2017;Krone, 2018;Manning, et al, 2018;Romero, et al, 2019;Monclús, et al, 2020;Hurtado, et al, 2020). Além disso, os efeitos no sistema reprodutivo incluem alteração no tamanho dos ovos e interferência no desenvolvimento embrionário e da ninhada (Monzalvo-Santos, et al, 2016;Yang, et al, 2020).…”

“…A exposição ao Pb no ambiente pode causar alterações nas populações de aves, afetando a eclodibilidade, o crescimento, sobrevivência, sucesso inicial dos filhotes, bem como problemas reprodutivos, tal qual a diminuição na produção de ovos devido baixa concentração plasmática de cálcio (Ding, et al, 2020). Yang et al (2020) investigaram alterações no sistema reprodutor de machos de Passer montanus, expostos ao ambiente contaminado por metais pesados em diferentes províncias da China. Ao avaliarem a atividade de algumas enzimas no sêmen, foi encontrada redução na atividade da superóxido dismutase (SOD).…”

O chumbo é um metal não essencial tóxico encontrado em diversas formas químicas, portanto, pode causar poluição atmosférica, terrestre e aquática. A principal fonte de chumbo se deve a ação antrópica, através da utilização de munições à base de chumbo, pesca, combustível, mineração, incineração de lixo e atividade industrial. O objetivo da presente revisão é demonstrar o conhecimento atual sobre as fontes de contaminação por chumbo, os sinais clínicos e lesões observadas em aves silvestres, diagnóstico e tratamento, impactos na biodiversidade e medidas de prevenção. Para a realização do estudo, foi utilizado pesquisa de artigos nas bases científicas PubMed, portal de periódicos CAPES, SciELO e Google Acadêmico, no recorte temporal de 2015 a 2020. A partir dos estudos elencados, observou-se que os animais são frequentemente encontrados com alterações subclínicas, clínicas ou mortos em seus habitats naturais. A literatura afirma que os efeitos do chumbo no organismo variam de acordo com a dose, tempo de exposição e via de intoxicação, logo, as consequências na saúde das aves silvestres são inúmeras. Concluiu-se que a substituição do chumbo por outros componentes, alterações em normativas e conscientização sobre seu descarte, resultam em ganhos na conservação da natureza e melhoria da biodiversidade.

“…Supplementation with antioxidants is regarded as a vital way to mitigate metal poisoning because metal contaminants can cause oxidative stress and decreased antioxidant capacity ( He et al, 2020 ; Yang Y. et al, 2020 ; Paithankar et al, 2021 ). Currently, polysaccharides extracted from animals and plants have been shown to be promising antioxidants ( Chen and Huang, 2018 , 2019 ).…”

Heavy metals released in the environment pose a huge threat to soil and water quality, food safety and public health. Additionally, humans and other mammals may also be directly exposed to heavy metals or exposed to heavy metals through the food chain, which seriously threatens the health of animals and humans. Chromium, especially hexavalent chromium [Cr (VI)], as a common heavy metal, has been shown to cause serious environmental pollution as well as intestinal damage. Thus, increasing research is devoted to finding drugs to mitigate the negative health effects of hexavalent chromium exposure. Seaweed polysaccharides have been demonstrated to have many pharmacological effects, but whether it can alleviate gut microbial dysbiosis caused by hexavalent chromium exposure has not been well characterized. Here, we hypothesized that seaweed polysaccharides could alleviate hexavalent chromium exposure-induced poor health in mice. Mice in Cr and seaweed polysaccharide treatment group was compulsively receive K2Cr2O7. At the end of the experiment, all mice were euthanized, and colon contents were collected for DNA sequencing analysis. Results showed that seaweed polysaccharide administration can restore the gut microbial dysbiosis and the reduction of gut microbial diversity caused by hexavalent chromium exposure in mice. Hexavalent chromium exposure also caused significant changes in the gut microbial composition of mice, including an increase in some pathogenic bacteria and a decrease in beneficial bacteria. However, seaweed polysaccharides administration could ameliorate the composition of gut microbiota. In conclusion, this study showed that seaweed polysaccharides can restore the negative effects of hexavalent chromium exposure in mice, including gut microbial dysbiosis. Meanwhile, this research also lays the foundation for the application of seaweed polysaccharides.

“…Sperm traits are known to be sensitive to heavy metal exposure which can result in decreased sperm count (Akinloye et al, 2006), viability (Chiou et al, 2008; Tabassomi & Alavi‐Shoushtari, 2013), motility (Hardneck et al, 2018; Kushawaha et al, 2021) and velocity (Hardneck et al, 2018; Naha & Chowdhury, 2006). Nevertheless, longer and faster sperm, which may be beneficial for reproductive success, has been found in BY compared with the populations in an unpolluted site nearby, Liujiaxia (LJX) (Yang, Zhang, Wang, Yang, et al, 2020; Yang, Zhang, Wang, Zhang, et al, 2020). In addition, tree sparrows in BY have shown significantly higher extra‐pair fertilisation than those in LJX, indicating that sperm competition may be more intense in heavy metal polluted environments (Yang et al, 2021).…”

Duplicate genes as sources for rapid adaptive evolution of sperm under environmental pollution in tree sparrow

Environmental pollution can result in poor sperm quality either directly or indirectly in birds. However, adaptive and compensatory sperm morphology changes and motility improvements have rapidly evolved in tree sparrows (Passer montanus) inhabiting polluted areas over the past 65 years. To identify the genetic underpinnings of the rapidly evolving sperm phenotype, we carried out population genomics and transcriptomics on tree sparrow populations in the two differently polluted places. We identified a gene encoding the serine/threonine protein kinase PIM1, which may drive rapid phenotypic evolution of sperm. An unprecedented and remarkable expansion of the PIM gene family, caused by tandem and segmental duplication of PIM1, was subsequently observed in the tree sparrow genome. Most PIM1 duplicates showed a testis-specific expression pattern, suggesting that their functions are related to male reproduction. Furthermore, the elevated expression level of PIM1 was consistent with our earlier findings of longer and faster swimming sperm in polluted sites, indicating an important role for duplicated PIM1 in facilitating the rapid evolution of sperm. Our results suggest that duplicated PIM1 provides sources of genetic variation that may enable the rapid evolution of sperm under environmental heavy metal pollution. The findings of this study indicated that duplicated genes can be targets of selection and predominant sources for rapid adaptation to environmental change and shed light on sperm evolution under pollution stress.
