Changes in belowground biodiversity during ecosystem development
(NATL ACAD SCIENCES, 2019)Belowground organisms play critical roles in maintaining multiple ecosystem processes, including plant productivity, decomposition, and nutrient cycling. Despite their importance, however, we have a limited understanding ... -
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 ... -
Climate and coastal low-cloud dynamic in the hyperarid Atacama fog Desert and the geographic distribution of Tillandsia landbeckii (Bromeliaceae) dune ecosystems
(SPRINGER WIEN, 2021-10)Despite the extensive area covered by the coastal Atacama fog Desert (18-32 degrees S), there is a lack of understanding of its most notorious characteristics, including fog water potential, frequency of fog presence, ... -
Community isolation drives lower fish biomass and species richness, but higher functional evenness, in a river metacommunity
(Wiley, 2020)The flow of individuals among communities and their interactions with local environmental filters are increasingly recognised as determinants of biodiversity patterns in riverine ecosystems. Both incoming dispersers and ... -
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 ... -
Continuous bioreactors enable high-level bioremediation of diesel-contaminated seawater at low and mesophilic temperatures using Antarctic bacterial consortia: Pollutant analysis and microbial community composition
(ELSEVIER SCI LTD, 2023-03-15)In 2020, more than 21,000 tons of diesel oil were released accidently into the environment with most of it contaminating water bodies. There is an urgent need for sustainable technologies to clean up rivers and oceans to ... -
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 ... -
Crop-Specific Effects on Pan-Trap Sampling of Potential Pollinators as Influenced by Trap Color and Location
(MDPI, 2023-03-20)Characterizing insect communities in pollinator-dependent crops helps determine the potential pollinator effectiveness and their effects on crop yield. Few studies have examined pollinator communities and their services ... -
Decoupling of biotic and abiotic patterns in a coastal area affected by chronic metal micronutrients disturbances
(PERGAMON-ELSEVIER SCIENCE LTD, 2021-05)Coastal systems are highly productive areas for primary productivity and ecosystem services and host a large number of human activities. Since industrialization, metal micronutrients in these regions have increased. ... -
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 ... -
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 ... -
Disentangling demographic co-effects of predation and pollution on population dynamics
(WILEY, 2019)In nature species react to a variety of endogenous and exogenous ecological factors. Understanding the mechanisms by which these factors interact and drive population dynamics is a need for understanding and managing ... -
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 ... -
Distinctive Archaeal Composition of an Artisanal Crystallizer Pond and Functional Insights Into Salt-Saturated Hypersaline Environment Adaptation
(FRONTIERS MEDIA SA, 2018)Hypersaline environments represent some of the most challenging settings for life on Earth. Extremely halophilic microorganisms have been selected to colonize and thrive in these extreme environments by virtue of a broad ... -
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 ... -
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 ... -
Environment and COVID-19: Pollutants, impacts, dissemination, management and recommendations for facing future epidemic threats
(Elsevier, 2020-12)Coronavirus disease 2019 (COVID-19) has become a global pandemic. Its relationship with environmental factors is an issue that has attracted the attention of scientists and governments. This article aims to deal with a ... -
