Invasion dynamics of the European bumblebee Bombus terrestris in the southern part of South America
(NATURE PORTFOLIO, 2021-07-27)Invasive species are one of the main biodiversity loss drivers. Some species can establish and thrive in novel habitats, impacting local communities, as is the case of managed pollinators. In this regard, an invasive ... -
Time-Based Systems Biology Approaches to Capture and Model Dynamic Gene Regulatory Networks
(ANNUAL REVIEWS, 2021-07-19)All aspects of transcription and its regulation involve dynamic events. However, capturing these dynamic events in gene regulatory networks (GRNs) offers both a promise and a challenge. The promise is that capturing and ... -
Soil bacterial community structure of fog-dependent Tillandsia landbeckii dunes in the Atacama Desert
(SPRINGER WIEN, 2021-09-06)The interplay between plants and soil drives the structure and function of soil microbial communities. In water-limited environments where vascular plants are often absent and only specialized groups of rootless plants ... -
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, ... -
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 ... -
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 ... -
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, ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
Insights into gene expression responses to infections in teleosts using microarray data: a systematic review
(Blackwell Publishing Asia, 2021-01)The rapid growth of production in aquaculture in the last decades has brought unwanted consequences affecting fish health and increasing the susceptibility to different infections. This systematic review aimed to analyse ... -
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 ... -
Taxonomic reassignment of Pseudohaptolina birgeri comb. nov. (Haptophyta)
(Allen Press Inc., 2020-11)The haptophyte genus Pseudohaptolina (formerly Chrysochromulina clade B1-3) currently harbours two species: Pseudohaptolina arctica and Pseudohaptolina sorokinii. In addition, Chrysochromulina birgeri is expected to belong ... -
A country's response to tackling plastic pollution in aquatic ecosystems: The Chilean way
