Partial Gene Sequencing of CYP1A, Vitellogenin, and Metallothionein in Mosquitofish Gambusia yucatana and Gambusia sexradiata

Bulletin of Environmental Contamination and Toxicology, 2016
Ground characteristics in the Yucatan Peninsula make recovery and treatment of wastewater very expensive. This situation has contributed to an increase of pollutants in the aquifer. Unfortunately, studies related to the effects of those pollutants in native organisms are scarce. The aim of this work was to obtain partial sequences of widely known genes

Effects of polycyclic aromatic hydrocarbons on biomarker responses in Gambusia yucatana, an endemic fish from Yucatán Peninsula, Mexico

Environmental Science and Pollution Research, 2021
Polycyclic aromatic hydrocarbons (PAHs) are petroleum components that, when dissolved in the aquatic environment, can disrupt normal animal physiological functions and negatively affect species populations. Gambusia yucatana is an endemic fish of the Yucatán Peninsula that seems to be particularly sensitive to the presence of PAHs dissolved in the ...

Cholinesterases in Gambusia yucatana: Biochemical Characterization and its Relationship with Sex and Total Length

Bulletin of Environmental Contamination and Toxicology, 2016
Since several reports have indicated that cholinesterases (ChE) type and distribution is species specific and that in some species there is a relationship among gender, size and ChE activities, characterization has been suggested. The aim of the present study was to characterize the ChE present in head and muscle of Gambusia yucatana (using selective ...

In vivo evaluation of three biomarkers in the mosquitofish (Gambusia yucatana) exposed to pesticides

Chemosphere, 2005
In this study, the acute toxicity and the in vivo effects of commercial chlorpyrifos, carbofuran and glyphosate formulations on cholinesterase (ChE), glutathione S-transferase (GST) and lactate dehydrogenase (LDH) activities of the mosquitofish (Gambusia yucatana) were investigated.

Review of the Gambusia yucatana Complex (Pisces: Poeciliidae) of Mexico and Central America

Copeia, 1985
The Gambusia yucatana complex (sensu Greenfield and Wildrick, 1984) was reviewed and shown to consist of two subspecies. Principal component analysis demonstrated that the populations from the northern Yucatan Peninsula form a group that is distinct from other populations directly to the south.

Effects of Polycyclic Aromatic Hydrocarbons in Gambusia yucatana, an Endemic Fish from Yucatán Peninsula, Mexico

Polycyclic Aromatic Compounds, 2020
The aim of this study was to analyze the effect of the acute exposition of polycyclic aromatic hydrocarbons (PAHs) in four different concentrations (4.37, 8.73, 17.46, 34.95 µg L−1) in Gambusia yuc...
