Hybridization in the Anthropocene – how pollution and climate change disrupt mate selection in freshwater fish

Biological reviews/Biological reviews of the Cambridge Philosophical Society, Journal Year: 2024, Volume and Issue: unknown

Published: Aug. 2, 2024

ABSTRACT Chemical pollutants and/or climate change have the potential to break down reproductive barriers between species and facilitate hybridization. Hybrid zones may arise in response environmental gradients secondary contact formerly allopatric populations, or due introduction of non‐native species. In freshwater ecosystems, field observations indicate that changes water quality chemistry, pollution change, are correlated with an increased frequency Physical chemical disturbances can alter sensory environment, thereby affecting visual communication among fish. Moreover, multiple compounds (e.g. pharmaceuticals, metals, pesticides, industrial contaminants) impair fish physiology, potentially phenotypic traits relevant for mate selection pheromone production, courtship, coloration). Although warming waters led documented range shifts, is ubiquitous few studies tested hypotheses about how these stressors hybridization what this means biodiversity conservation. Through a systematic literature review across disciplines (i.e. ecotoxicology evolutionary biology), we evaluate biological interactions, toxic mechanisms, roles physical change) disrupting preferences inducing interspecific Our study indicates change‐driven impact crucial choice thus could fishes ecosystems. To inform future conservation management, emphasize importance further research identify choice, understand mechanisms behind determine concentrations at which they occur, assess their on individuals, species, diversity Anthropocene.

Personality Affects Zebrafish Response to Sertraline

Environmental Toxicology and Chemistry, Journal Year: 2023, Volume and Issue: 43(1), P. 132 - 146

Sertraline is widely prescribed to treat anxiety and depression. acts by blocking serotonin, norepinephrine, dopamine transporters systems has been detected in surface waters globally, where it may impact fish behavior. We classified zebrafish personality on three behavioral axes, boldness, anxiety, sociability, assigning as either high or low each category. The were exposed nominal concentrations of 0, 5, 50, 500, 5000 ng/L sertraline (measured concentrations: <10, 21.3, 370, 2200 ng/L, respectively) assess changes sociability after 7 28 days. also measured shoaling behavior response an alarm cue, determined the gut microbiome a subset fish. After days there was no overall effect but interaction between initial sex, with stronger females low-boldness personality. reduced all treatments compared control, again Fish that low-sociability responded more strongly sertraline. days, concentration (2200 measured) showed higher than controls, pattern retained. similar patterns observed, variation. There only weak association Overall, study highlights importance considering behavior, which can affect pollutants.

Removal of imipramine using advanced oxidation processes: Degradation products and toxicity evolution

Journal of Environmental Science and Health Part A, Journal Year: 2023, Volume and Issue: 58(4), P. 359 - 368

Published: March 9, 2023

AbstractAbstractPharmaceuticals are frequently detected in natural and wastewater bodies, very important environmental toxicology because of their stable nature. Advanced oxidation methods used to remove contaminants great benefit, especially removing pharmaceuticals unsuitable for biodegradation. In this study, imipramine was degraded by anodic subcritical water oxidation, which advanced methods. The determination degradation products performed Q-TOF LC/MS analysis. genotoxicity cytotoxicity the samples were determined vivo Allium Cepa method. Among samples, lowest obtained after using 400 mA current, 420 min time. No cytotoxic effect observed any sample. However, when 10 mM hydrogen peroxide as an oxidant at 150 °C reaction time 90 min, sample showed a genotoxic effect. results study that it is crucial evaluate toxicity levels preferred imipramine. optimum conditions both can be preliminary step biological imipramine.Keywords: Anodic oxidationsubcritical oxidationallium cepa assaycytotoxicitygenotoxicity AcknowledgmentsWe want thank Dr. Asena Ayça Özdemir (Mersin University Faculty Medicine, Department Biostatistics Medical Informatics) her contribution statistical analysis.Disclosure statementNo potential conflict interest reported authors.Data availability statementThe authors confirm data supporting findings available within article [and/or] its supplementary materials.Additional informationFundingThe author(s) there no funding associated with work featured article.
