Protistan Plankton Responses to Variable Light and Upwelling in the Peruvian Humboldt Current System: Insights Into Community Dynamics Under Environmental Change. [PDF]

Ecol Evol
Our study reveals (based on experiments) the shifts in protistan plankton communities, serving as energy and organic matter source for higher trophic levels if the Humboldt Current System is affected by climate change as predicted by current models. This may have profound effects on fisheries in the Humboldt Current System.

Infection of Dreissena polymorpha (Bivalvia: Dreissenidae) with Conchophthirus acuminatus (Ciliophora: Conchophthiridae) in lakes of different trophy

BioInvasions Records, 2012
The freshwater invasive mollusc Dreissena polymorpha and its host-specific commensal ciliate Conchophthirus acuminatus represent a convenient model to study various aspects of symbiotic relationships. This study was conducted to test whether the nutrient enrichment of waterbodies inhabited by D. polymorpha is associated with C.

Mass Azithromycin Distribution and Community Microbiome: A Cluster-Randomized Trial. [PDF]

, 2018
BackgroundMass distributions of oral azithromycin have long been used to eliminate trachoma, and they are now being proposed to reduce childhood mortality. The observed benefit appears to be augmented with each additional treatment, suggesting a possible
