Bacterial richness assessment in water and sediments in the northern coast of the Yucatan Peninsula.

Given the importance of the coastal environments and the multiple ecological services that they provide, it is important to explore and understand the interactions that occur within them. The microbiome is a key factor for the understanding of the dynamics of these fragile sites. A metagenomic study based on the profiling of the 16S ribosomal gene was carried out in order to assess the bacterial diversity present in the northern coastal zone of the Yucatan Peninsula.

Adsorption of organophosphorus pesticides in tropical soils: The case of karst landscape of northwestern Yucatan.

This article discusses the adsorption of four organophosphorus pesticides-diazinon, dimethoate, methyl parathion, and sulfotep-in soil samples from four sites-Komchén, Xcanatún, Chablekal and Mocochá- in the northwest of Yucatan, Mexico. These pesticides have been detected in groundwater at concentrations greater than 5 (μg/L) during recent monitoring campaigns in the study area. In this region, groundwater contamination is exacerbated by its karst aquifer, which is susceptible to contamination and is considered very vulnerable.
