Phytoplankton Abundance and Species Composition in Relation to Environmental Paramenters in Coastal Mississippi Waters

Phytoplankton pigments from Coastal Mississippi waters were measured to determine the spatial and temporal distributions and composition of phytoplankton communities. Concentration of phytoplankton pigments were analyzed using High Performance Liquid Chromatography (HPLC) and the compositional changes in phytoplankton communities were determined with CHEMTAX 1.95. Surface water was collected for two years (September 2007-November 2009) at three sampling sites on a monthly basis. The stations were located at the Bay of St. Louis (station 1), the Mississippi Sound (station 4) and the Mississippi Bight (station 8), following a salinity gradient. A time series of the observations documented the variability of different taxonomic groups and phytoplankton abundance in Mississippi waters. Phytoplankton abundance and species group composition were related to environmental variables. Phytoplankton abundance did vary within stations and seasons being greater in coastal waters during the summer months. Diatoms were the major group at stations 1 and 4 where there was no major seasonal trend. At station 8 there was a clear seasonal trend where diatoms predominated in the winter, prymnesiophytes increased in spring, and cyanobacteria and diatoms predominated during the summer

Perspectives and assessment of psychosocial risk in latin America: A systemic review of the literature

The purpose of this systematic review was to analyze the perspectives and evaluations of psychosocial risk in Latin America. The reviews of the articles were carried out independently complying with the inclusion and exclusion criteria, 15 were the articles that met the inclusion, criteria analyzed by the 8 dimensions, and in these studies, it was observed that the qualitative approach predominated, with non-experimental and cross-sectional design with descriptive scope, these searches were carried out through the Web of Science (WOS), Scopus and ProQuest databases. The results showed that psychosocial risk factors are related to social class and can be used as tools to propose interventions to reduce inequalities in health, socioeconomic status, and gender. The importance of research associated with the development of strategies for the prevention and promotion of psychosocial risk factors is discussed

Systematic literature review: Mental health promotion in organizations during the pandemic by COVID-19

It is essential to review the working conditions of the organizations and the risk factors that arose in the midst of the pandemic and that generated repercussions on the mental health of the collaborators, highlighting the strategies or protective factors that were used to reduce them. Objective: To characterize the strategies and programs implemented by different organizations as mental health promotion responses during the COVID-19 pandemic
