Abstract

In this issue, Revista Bio Ciencias brings readers seven articles with diverse topics on biological sciences, from molecular to biochemical, and ecological
and systematic aspects.

The first manuscript corresponds to a review article that talks about the recurrent topic on insects’ resistance to pesticides, phenomenon that has provoked a higher and indiscriminate use of these substances.

The second document, signed by Vega-Villasente F, et al, is a report on the presence of the ectoparasite Argulus spp. and how its infection provokes from tissue damages to behavior alterations in the native fish of the tropical Mexican Pacific.

On the other hand, Galaviz-Villa et al, describe some virus factors of Vibrio parahemolyticus detected in oysters from the Gulf of Mexico, which can become a risk factor in feeding infections.

In the ecological context and anthropogenic alterations, López-Monroy et al, argue on the enrichment of water bodies with elements such as nitrogen and phosphorus, these are responsible of the trophic alterations of this type of ecosystems; thus, they present as case study a hypersaline lagoon from the Venezuelan coast.

The fifth document presented in this issue, Solis-Juarez et al, perform a morphological description of the lateral line of stingray Urotrygon rogersi, proposing a factor that could become key to distinguish species in this type
of organisms.

In the zoo-technical and productive area, Alvarado-Canché et al, analyze the productive and feeding behavior of sheep in the Peninsula of Yucatan, proposing two species of gramineous that can be useful in both dry and rainy seasons.

Finally, researchers from the State University of Nayarit propose methodological basis to study the seasonalvariations of the continental oceanographic platform, an important topic highly influenced and/or provoked by the phenomenon of climate change.

Hence, Revista Bio Ciencias emphasizes its transdisciplinary vocation in the field of biological sciences, consolidating as a discussion and scientific analysis forum.
