The coastal areas of Mexico have high economic, sociopolitical, and ecological value, and are threatened by climate change and anthropogenic activity. Due to this, it`s necessary to generate vulnerability studies to estimate the impact of these factors on the organisms that inhabit them. The study of the vulnerability of any...
Holothurians, commonly known as sea cucumbers, belong to the Phylum echinoderms. These marine organisms contain a wide variety of active ingredients, such as carbohydrates, lipids, neurotoxins and enzymes. The knowledge of digestive enzymes in the sea cucumber could clarify its nutritional biochemistry and physiology. Determining the digestive capabilities of these...
Las actividades antropogénicas han perjudicado al ambiente y a diversos organismos que en él habitan. Las almejas se han propuesto como bioindicadores ya que permiten una visión integral y retrospectiva de las cualidades del medio en el que se desarrollan. En México existen sitios de importancia turística, comercial y riqueza...
The vulnerability depends on the analysis of the elements that compose it: exposure, sensitivity, and recovery capacity. In this work, the use of tissue responses that have been recommended as biomarkers to measure the elements of vulnerability in the Polymesoda caroliniana clam is proposed, in addition to obtaining a histopathological...
Los organismos marinos se han adaptado a diferentes condiciones ambientales a través del tiempo, estas adaptaciones se han traducido en proteasas con propiedades únicas. Los pepinos de mar son invertebrados del fondo marino apreciados en la gastronomía oriental por su alto valor nutricional y compuestos bioactivos. Dichos organismos poseen un...
In environmental monitoring, the qualitative evaluation of histological alterations has been proposed as a biomarker to evaluate the effects of contamination in aquatic organisms. However, quantitative analysis tools that allow the determination of the health of wild or experimental organisms are not considered. The aim was to calculate the health...
In the environmental monitoring it has been pointed out the importance of using histopathological scoring system protocols to determine environmental stress. Therefore, the aim of this study was to evaluate semi-quantitatively the histopathological changes in the liver, gills and muscle of the fish Scomberomorus cavalla to determine the health status...
Jellyfish has been recently recognized as an important fishing resource in Asia as well as in America. However, only few classes are edible. Until recently, the Mexican industry began to show interest in fishing for Stomolophus meleagris, known as “cannonball jellyfish”. In this continent, cannonball jellyfish catching is practiced along...
Las alteraciones en eritrocitos aportan información sobre el estado de salud de los peces así como del medio en el que se desarrollan. Sin embargo, estas alteraciones no han sido bien categorizadas de forma semicuantitativa. Es importante conocer la importancia patológica de las alteraciones en eritrocitos para generar protocolos de...
The phylum Cnidarian contains about 11,000 species, the jellyfishes has cells specialized (cnidocitos) that contain toxins; this toxins have the potential to be a tool with which to study some complex physiological systems, in addition to being used for the manufacture of new drugs and obtaining knowledge of its operation...
