Los Hidrocarburos aromáticos policíclicos (HAPs) son contaminantes persistentes, que se transportan por aire y por medio de partículas que se acumulan en el sedimento, y entran a la cadena alimenticia del detritus. Estos contaminantes tienen un alto potencial carcinógeno y mutágeno. En este estudio se analizaron 16 HAPs, considerados prioritarios...
One of the most conspicuous groups, both for its abundance and ecological and economic importance, are the Oscillatoriales, with a filamentous thallus, without specialized cells such as heterocytes and akinetes, many of which form BLOOMs potentially toxic, due to the production of hepatotoxins, neurotoxins and cytotoxins. However, the main bibliographic...
Bats are hosts a several amount of viruses, some of them zoonotic, causing pandemics (e.g., Nipah, coronavirus). It is speculated that occur a coevolutionary relationship between both, hence the scientists have investigated this association generating a large amount of information (phylogenetic, evolutionary, immunological, viral transmission) that must be analyzed and...
This work was carried out during the 2020-2022 COVID quarantine and is a compilation and analysis of online information: bibliographic, scientific collections and databases (SNIB, GBIF and NaturaLista, INAI). The objectives of this work were: 1) To compile information on the arboreal cacti of Mexico (geographic distribution and uses); 2)...
Orchids are widely recognized for the great complexity of their floral morphology and the high specialization in their pollination. The genus Rhynchostele is included in the subtribe Oncidiinae, includes 18 species, and has a neotropical distribution. In Mexico it is well represented with 15 species. The pollinary, traditionally, has been...
Gracilaria flabelliformis is a widely distributed species ranging from southern Florida to northern Brazil. In the Mexican Atlantic, it’s particularly found along the coasts of Veracruz and the Yucatán Peninsula. Currently, it’s considered part of the G. mammillaris complex, which encompasses five morphologically similar Gracilaria species that exhibit sympatric distribution....
El fitoplancton es una comunidad de alta importancia para los ambientes marinos, cumple un papel fundamental en la productividad primaria y las redes tróficas. En esta comunidad destacan los dinoflagelados por su importancia ecológica. Diversos grupos de dinoflagelados han sido pobremente estudiados debido a la naturaleza de las células, donde...
The cyanoprokaryotes of the order Nostocales constitute a monophyletic, ecologically and taxonomically very diverse group, commonly associated with red algae, and at the same time, one of the least studied orders. They are characterized by presenting heterocytes (structure responsible for nitrogen fixation) and akinetes (resistance structures). Both rhodophyta and cyanoprokaryota...
El análisis de las características biológicas específicas de cada población de Artemia permite evaluar, desde el punto de vista evolutivo, la gama de respuestas de la especie y de las poblaciones a un ambiente en particular y sus consecuencias, por ejemplo, la diferenciación morfométrica y el aislamiento reproductivo. En este...
Fisheries activities produce large quantities of non-recycled wastes all over the world. In Mexico, shrimp commercial captures and cultures generate high quantities of non-used heads. It is calculated that these wastes reach up to 32,000 annual tons and only 5% is converted in shrimp meal. In the present work we...
