This study evaluated the physicochemical properties and the concentrations of metal(oid)s in soils with approximately 5, 20 and 40 years of sugarcane cultivation from a locality in Quintana Roo, Mexico. The results showed the metal(oid) concentration order Fe > Cr > V > Pb > Co > Cu > As, with a gradual increase in their concentrations up to 33,834...
In the present study, we evaluated the biological response of Achirus lineatus to water accommodated fraction (WAF) of light crude oil (American Petroleum Institute gravity 35°) during a sub-chronic bioassay (14 and 28 days) at two different concentrations: 5% v/v (1.20 µg∙L− 1 expressed as total polycyclic aromatic hydrocarbons [∑25 PAH]) and 10%...
The amount of Sargassum spp. arriving in the Caribbean Sea has increased steadily in the last few years, producing a profound environmental impact on the ecological dynamics of the coasts of the Yucatan Peninsula. We characterized the toxicological effects of an ethanolic extract of Sargassum spp. on zebrafish (Danio rerio) embryos (ZFEs) in a 96-h...
The present study evaluates the endocrine effect in flatfish through vitellogenin (vtg) gene expression and its association with pollutants data obtained from fish muscle and sediment from two regions in the Gulf of Mexico (GoM): Perdido Fold Belt (northwestern) and the Yucatan Peninsula (southeast). The results revealed induction of vtg in male fl...
Microplastics (MPs) are emerging pollutants of widespread concern in aquatic environments. The aim of this study was to evaluate the negative impact of pristine MPs of polystyrene of 100 μm on embryo and larvae of Danio rerio exposed to three environmentally relevant concentrations of polystyrene (3.84 × 10− 6, 3.84 × 10− 7, and 3.84 × 10− 8 g/mL)....
The impacts of selective logging on arbuscular mycorrhiza and bacteria of tropical forests are little known globally. In this study, we analysed and compared the composition and diversity of bacteria and arbuscular mycorrhizal fungi (AMF) in a forest with sustainable management (stands with 6-years-old after selective logging) compared with a conse...
Dioctyl Sodium Sulfosuccinate (DOSS, CAS 577-11-7) is a chemical emulsifying surfactant that is widely used in the food and the cosmetic industry, and it is also the major component of the crude oil chemical dispersant Corexit™. Despite of its wide use, the studies related to its negative effect have been evaluated mainly in marine environments sho...
The effects of crude oil spills are an ongoing problem for wildlife and human health in both marine and freshwater aquatic environments. Bioassays of model organisms are a convenient way to assess the potential risks of the substances involved in oil spills. Zebrafish embryos (ZFE) are a useful to reach a fast and detailed description of the toxici...
In this study, we report molecular and metabolic responses of Sciaenops ocellatus during an acute oil exposure bioassay (100, 800 and 8000 mg 1–1 of crude oil). The global DNA methylation and expression profiles of key genes of the xenobiotic biotransformation system (cytochrome P450 1A [cyp1a] and glutathione S-tranferase [gst]), oxidative stress...
Benzo[a]pyrene (BaP), a lipophilic polycyclic aromatic hydrocarbon (PAH), is a contaminant widely distributed in aquatic systems. Its presence in freshwater organisms is of great concern; particularly in Nile tilapia (Oreochromus niloticus), due to its economic relevance. The aim of this study is to evaluate the effects of acute and sub-chronic BaP...
La evaluación de la exposición de los organismos a sustancias químicas puede determinarse a nivel molecular a través de biomarcadores moleculares involucrados con la biotransformación de xenobióticos. En este estudio, se evaluaron los niveles de expresión génica de Citocromo P450 1A (CYP1A) en peces planos colectados en dos zonas al sureste del Gol...
The aim of this study was to estimate allelic and genotypic frequencies of markers in the leptin (LEP), pituitary transcription factor (PIT-1) and luteinizing hormone receptor (LHR) genes and evaluate their effects on reproductive traits and milk yield of Holstein cattle. Data from 147 cows from department of Francisco Morazán, Honduras, were colle...
En este artículo se fundamenta teóricamente una unidad didáctica, dirigida a estudiantes de grado noveno, relacionada con el concepto de herencia mendeliana, en la que se busca abordar la enseñanza de la genética de una manera más dinámica, ya que esta ciencia se considera básica para la comprensión de muchos de los fenómenos biológicos, para lo cu...
La vegetación nativa ha cumplido un papel importante a través del tiempo en el desarrollo e identidad de las comunidades. Esta no se limita estrictamente a una función biológica o ecológica en un ecosistema; sino que también interviene en aspectos culturales y sociales de la población humana. A pesar de ello, en la actualidad se ha visto que existe...
