Legacy and novel flame retardants from indoor dust in Antarctica: Sources and human exposure
(Chile. Universidad Mayor, 2020)The air humidity in Antarctica is very low and this peculiar weather parameter make the use of flame retardants in research facilities highly needed for safety reasons, as fires are a major risk. Legacy and novel flame ... -
Effects of long-lasting social isolation and re-socialization on cognitive performance and brain activity: a longitudinal study in Octodon degus
(Chile. Universidad Mayor, 2020)Social isolation is considered a stressful situation that results in increased physiological reactivity to novel stimuli, altered behaviour, and impaired brain function. Here, we investigated the effects of long-term social ... -
Geographical origin determines responses to salinity of Mediterranean caddisflies
(Public Library of Science, 2020-01-13)Many freshwater ecosystems worldwide, and particularly Mediterranean ones, show increasing levels of salinity. These changes in water conditions could affect abundance and distribution of inhabiting species as well as the ... -
Characterizing the microbiomes of Antarctic sponges: a functional metagenomic approach
(Nature Publishing Group, 2020-01-20)Relatively little is known about the role of sponge microbiomes in the Antarctic marine environment, where sponges may dominate the benthic landscape. Specifically, we understand little about how taxonomic and functional ... -
Eco-hydrological Functions in Forested Catchments of Southern Chile
(Springer New York, 2020-03)Ecosystem functions in forests can vary significantly after disturbance, depending on changes in vegetation structure during succession and soil biophysical characteristics. We examined streamflow regulation, water storage ... -
Monitoring the occurrence of microplastic ingestion in Otariids along the Peruvian and Chilean coasts
(Elsevier Inc., 2020-04)Repeated reports of microplastic pollution in the marine pinniped diet have emerged in the last years. However, only few studies address the drivers of microplastics presence and the potential implications for monitoring ... -
Pollinator declines and the stability of plant-pollinator networks
(Wiley-Blackwell, 2020-04)Population declines of pollinators constitute a major concern for the fate of biodiversity and associated ecosystem services in a context of global change. Massive declines of pollinator populations driven by habitat loss, ... -
Fungal Diversity Analysis of Grape Musts from Central Valley-Chile and Characterization of Potential New Starter Cultures
(Univ Mayor, GEMA Ctr Genom Ecol & Environm, Chile, 2020-06)Autochthonous microorganisms are an important source of the distinctive metabolites that influence the chemical profile of wine. However, little is known about the diversity of fungal communities associated with grape ... -
Development and analytical validation of real-time PCR for the detection ofStreptococcus agalactiaein pregnant women
(BioMed Central Ltd., 2020-06)Background Group BStreptococcus(GBS) is the leading cause of invasive neonatal infection. In this study, we aimed to evaluate the analytical validation of qualitative real-time polymerase chain reaction (qPCR) as a means ... -
Core-periphery dynamics in a plant-pollinator network
(Wiley-Blackwell Publishing Ltd, 2020-07)Mutualistic networks are highly dynamic, characterized by high temporal turnover of species and interactions. Yet, we have a limited understanding of how the internal structure of these networks and the roles species play ... -
Isolation and Identification of Soil Bacteria from Extreme Environments of Chile and Their Plant Beneficial Characteristics
(MDPI AG, 2020-08)The isolation of soil bacteria from extreme environments represents a major challenge, but also an opportunity to characterize the metabolic potential of soil bacteria that could promote the growth of plants inhabiting ... -
Distinct oxygen environments shape picoeukaryote assemblages thriving oxygen minimum zone waters off central Chile
(Oxford University Press, 2020-09)Oxygen minimum zones (OMZs) support ocean biogeochemical cycles of global importance. The OMZ off central Chile is characterized by seasonally variable oxygen concentrations due to upwelling events. Bacterial and archaeal ... -
Pharmacological iron-chelation as an assisted nutritional immunity strategy against Piscirickettsia salmonis infection
(BioMed Central Ltd., 2020-10)Salmonid Rickettsial Septicaemia (SRS), caused by Piscirickettsia salmonis, is a severe bacterial disease in the Chilean salmon farming industry. Vaccines and antibiotics are the current strategies to fight SRS; however, ... -
Connectivity of bacterial assemblages along the Loa River in the Atacama Desert, Chile
(PeerJ Inc., 2020-10)The Loa River is the only perennial artery that crosses the Atacama Desert in northern Chile. It plays an important role in the ecological and economic development of the most water-stressed region, revealing the impact ... -
Sources and diffusive air-water exchange of polycyclic aromatic hydrocarbons in an oligotrophic North-Patagonian lake
(Elsevier, 2020-10)Polycyclic aromatic hydrocarbons (PAHs) are semivolatile organic compounds of environmental concern. This study aims to investigate the influence of local sources of anthropogenic PAHs and their air-water exchange fluxes ... -
Self-Compatibility Not Associated with Morphological or Genetic Diversity Reduction in Oil-Rewarding Calceolaria Species
(MDPI Multidisciplinary Digital Publishing Institute, 2020-10)One of the most common evolutionary transitions in angiosperms is the reproductive change from outcrossing to selfing, commonly associated with changes in floral biology and genetic diversity. Here, we aim to test whether ... -
Different Pollinators' Functional Traits Can Explain Pollen Load in Two Solitary Oil-Collecting Bees
(MDPI Multidisciplinary Digital Publishing Institute, 2020-10)Pollinators' features, especially those with a functional role during the pollination process, have been shown to be a good predictor of pollen load for some bee species, but little is known about solitary bees. Here, I ... -
