A ECOTOXICOLOGIA COMO FERRAMENTA NO BIOMONITORAMENTO DE ECOSSISTEMAS AQUÁTICOS [PDF]

Oecologia Australis, 2008
Ecotoxicology is a science created to solve problems with water contamination by toxic compounds. The analytical framework employed is capable of predicting biological responses to the toxicity of chemical compounds through concentration-effect and concentration-response curves, and also enables evaluating the ecotoxicity of disturbed environments ...

Ecotoxicologia: conceitos, abrangência e importância agronômica

Revista Monografias Ambientais, 2011
O emprego de produtos químicos na agricultura tem sido incrementado especialmente na segunda metade do século passado até os dias atuais, constituindo um tema de estudo e constantes debates em função dos riscos de contaminação de águas, solos, atmosfera e humana iminentes quando utilizados de forma indiscriminada.

In Vivo Inflammatory Effects of Ceria Nanoparticles on CD-1 Mouse: Evaluation by Hematological, Histological, and TEM Analysis

Journal of Immunology Research, 2014
The attention on CeO2-NPs environmental and in vivo effects is due to their presence in diesel exhaust and in diesel filters that release a more water-soluble form of ceria NPs, as well as to their use for medical applications.

O USO DE COLLEMBOLA (INSECTA) COMO ORGANISMO-TESTE EM BIOENSAIOS NA ECOTOXICOLOGIA

Pesticidas: Revista de Ecotoxicologia e Meio Ambiente, 1993
O uso intensivo de agrotóxicos pode provocar danos irreversíveis aos alimentos ecológicos do solo. Sendo os insetos da Ordem Collembola um dos de maior importância biológica ao solo, estes podem ser usados na detecção de resíduos de agrotóxicos no solo, através de bioensaios de ecotoxicologia.

Population origin determines the adaptive potential for the advancement of flowering onset in Lupinus angustifolius L. (Fabaceae). [PDF]

Evol Appl, 2023
Abstract In the present framework of global warming, it is unclear whether evolutionary adaptation can happen quick enough to preserve the persistence of many species. Specifically, we lack knowledge about the adaptive potential of the different populations in relation to the various constraints that may hamper particular adaptations. There is evidence

Assisted Gene Flow Management to Climate Change in the Annual Legume <i>Lupinus angustifolius</i> L.: From Phenotype to Genotype. [PDF]

Evol Appl
ABSTRACT Climate change may hinder species' ability to evolutionarily adapt to environmental shifts. Assisted gene flow, introducing adaptive alleles into target populations, could be a viable solution for keystone species. Our study aimed to evaluate the benefits and limitations of assisted gene flow in enhancing the evolutionary potential of Lupinus ...

Does the dose make the poison? Neurotoxic insecticides impair predator orientation and reproduction even at low concentrations. [PDF]

Pest Manag Sci, 2022
Neurotoxic insecticides negatively affected the behavior and reproduction of the predator Nesidiocoris tenuis, even at low concentrations. Our study suggest that these compounds should be avoided when the presence of the predator is desirable. Abstract BACKGROUND Pesticides can be noxious to non‐target beneficial arthropods and their negative effects ...

Effects of a Dietary Multienzyme Extract on Isotope Biokinetics in Red Claw Crayfish Cherax quadricarinatus Juveniles. [PDF]

Aquac Nutr
Understanding the nutritional and metabolic physiology of aquatic organisms is essential for optimizing aquaculture practices and informing ecological models. We investigated the influence of dietary composition, specifically the incorporation of multienzyme extract derived from Pleoticus muelleri waste, on the growth and metabolic processes of ...

Chemical effects on dye efflux activity in live zebrafish embryos and on zebrafish Abcb4 ATPase activity

FEBS Letters, Volume 595, Issue 6, Page 828-843, March 2021., 2021
ATP‐binding cassette (ABC) transporter proteins include efflux pumps that confer multixenobiotic resistance to zebrafish embryos, a valuable toxico/pharmacological model. Here, we established an automated microscopy‐based rhodamine B dye accumulation assay in which enhanced dye accumulation in live zebrafish embryos indicates inhibition of ...

Exposição crônica ao cloridrato de metformina e à glibenclamida causa alterações comportamentais, glicêmicas e de mortalidade em Hemigrammus caudovittatus e Danio rerio [PDF]

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2019
RESUMO Hemigrammus caudovittatus e Danio rerio foram expostos aos hipoglicemiantes orais (HOs) cloridrato de metformina a 40µg/L e 120µg/L e glibenclamida a 0,13µg/L e 0,39µg/L durante 100 dias.
