A country's response to tackling plastic pollution in aquatic ecosystems: The Chilean way
(Chile. Universidad Mayor, 2021)Marine plastic pollution is worse than expected, and we are starting to realize its full extent and severity. Solving the plastic pollution problem is not easy, as it requires the action and commitment of all sectors of ... -
Age-Dependent Behavioral and Synaptic Dysfunction Impairment Are Improved with Long-Term Andrographolide Administration in Long-Lived Female Degus (Octodon degus)
(MDPI, 2023-01)In Octodon degus, the aging process is not equivalent between sexes and worsens for females. To determine the beginning of detrimental features in females and the ways in which to improve them, we compared adult females ... -
Assessing Ecological Indicators for Remnant Vegetation Strips as Functional Biological Corridors in Chilean Vineyards
(MDPI, 2021-09)Mediterranean central Chile is globally recognized as a hotspot for terrestrial biodiversity due to its high endemism and massive habitat loss. However, within the rural landscape of central Chile, significant extents of ... -
Avoiding artifacts when varying the number of species in ecological models
(WILEY, 2021-09)Ecological theory recognizes the importance of the variety of species for maintaining the functioning of ecosystems and their derived services. We assert that when studying the effects of shifts in biodiversity levels using ... -
Bacterial community structure in a sympagic habitat expanding with global warming: brackish ice brine at 85-90 degrees N
(NATURE PUBLISHING GROUP, 2019)Larger volumes of sea ice have been thawing in the Central Arctic Ocean (CAO) during the last decades than during the past 800,000 years. Brackish brine (fed by meltwater inside the ice) is an expanding sympagic habitat ... -
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 ... -
