Milton Barcos-AriasLos productos farmacéuticos (PFs) constituyen un grupo importante de los contaminantes emergentes (CE), debido a su potencial para inducir efectos fisiológicos adversos a bajas concentraciones en humanos y animales. Muchos estudios alrededor del mundo han reportado la presencia de un sin número de estos compuestos en diferentes medios acuáticos, lo que genera preocupación por los posibles efectos negativos que se producen en el agua, en la salud humana y la vida silvestre. En este contexto, este artículo tiene por objetivo presentar una revisión de los aspectos más relevantes sobre la presencia de PFs en el agua en un ámbito global desde el año 2010 hasta el 2019. El mayor número de estudios reportan presencia de contaminantes emergentes incluyendo fármacos de diferentes tipos en aguas superficiales, aguas subterráneas, aguas residuales y agua potable. Las principales fuentes de ingreso de fármacos en los sistemas acuáticos provienen de las aguas residuales que recogen aguas domésticas, efluentes hospitalarios y efluentes de fábricas sin tratamiento o inadecuadamente tratadas antes de ser liberadas a ríos y mares. La presencia de PFs en el ambiente acuático preocupa por su persistencia, la bioacumulación, la toxicidad y la generación de resistencia a antibióticos de muchos microorganismos, entre otras consecuencias aún no estudiadas en el ambiente.

Rebeca Elizabeth Moreira-GómezEricaceae are a group of plants with biotechnological and commercial importance. These plants establish symbiotic associations with a wide group of mycorrhizal fungi. National and global studies have focused on two of them: arbuscular endomycorrhizae and ectomycorrhizae. The most recent type of mycorrhiza recorded is the cavendishioid ectendomycorrhizae. The cavendishioid is one of the least-studied and understood mycorrhizae, along with monotropoid and arbutoid mycorrhizae. Among the potentialities of these ectendomycorrhizae are the alleviation of environmental stress, the facilitation of establishment, survival, the ability to form dual mycorrhizae, and their importance as a fundamental biological element of plant ecological successions. However, the factors that influence or correlate with the diversity of some of these fungal guilds, as well as the functional significance of their associations, are still unknown. The present review focuses on ericoid mycorrhiza from Ecuador in order to promote their study and thus take advantage of the benefits that they provide to endemic species and those of commercial interest. This material contributes significantly to reducing research gaps and channeling applied projects in the biological sciences.

Milton Barcos-AriasIn recent years, new data on the diversity of genera and species in the phylum Glomeromycota continue to be added and rearranged. Arbuscular mycorrhizal fungi are key to plant nutrition and agriculture. Studies report different short- and long-term cultivation practices that influence the abundance and diversity of Glomeromycota. To the best of our knowledge, there are no known studies of the fungal communities in the fine aroma cocoa cultivars. In this context, our work aims to discover the diversity of arbuscular mycorrhizae associated with two cocoa cultivation practices (conservative and semi-conservative) through the isolation of spores using microscopy and metabarcoding of the internal transcribed spacer region (ITS). Morphological analysis showed that the density of Glomeromycota spores exhibited significant differences between production systems. Although the metabarcoding analysis showed that diversity indices showed a higher increase in the roots than in the cocoa soil, independently of the cultivation practice. An abundance of 348 and 114 taxa were observed, corresponding to the conservative and semi-conservative practices, respectively. Seven genera were observed for the first time in cocoa crop agroforestry systems, including P. scintillans, R. diaphanus, R. fasciculatus, R. custos, D. disticha, M. perpusilla, and D. bernensis.

About Me
PhD. Milton Barcos, is an Agricultural Engineer by training, and has two Master's degrees in Biotechnology and a Doctorate in Sciences with a specialty in Plant Biotechnology from the Center for Research and Advanced Studies of the National Polytechnic Institute of Mexico (CINVESTAV-IPN). He currently works as a professor in the Faculty of Life Sciences of the Escuela Superior Politécnica del Litoral (ESPOL). Since 2001 he has been working at the Biotechnological Research Center of Ecuador (CIBE-ESPOL) in improving banana cultivation from the nutritional aspect with organic amendments, to selection assisted by molecular markers. In 2014 he was appointed Head of the CIBE Environmental Bioremediation Laboratory, since then he has been working on issues of microbial bioremediation, phytoremediation and the production of bioproducts seeking to restore agricultural areas that are strongly affected by different types of anthropogenic activities. In Postgraduate studies, he has taught and coordinated the Introduction to Biodiscovery Module in the different cohorts of the Master's Degree in Applied Biosciences of the VLIR-ESPOL Program. Likewise, he has given the modules of Introduction to Biodiscovery, Metabolomics and Bioremediation in the first cohort of the Doctoral Program in Applied Biosciences of FCV-ESPOL. He is the tutor of numerous undergraduate and postgraduate theses. And he has published several articles in indexed magazines.
