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 ... -
Environmental signature and health risk assessment of polybrominated diphenyl ethers (PBDEs) emitted from a landfill fire in Santiago de Chile
(ELSEVIER SCI LTD, 2023-08-01)Polybrominated diphenyl ethers (PBDEs) have been used as flame retardants in building materials, electronics, furnishings, vehicles, airplanes, plastics, polyurethane foams, and textiles for many years. Currently, the ... -
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 ... -
Wild Floral Visitors Are More Important Than Honeybees as Pollinators of Avocado Crops
(MDPI, 2023-08-12)Wild insects provide pollination services in agroecosystems. Avocado is an economically important crop grown in the Chilean Mediterranean climate region and exported worldwide. Avocado pollination is managed using honeybee ... -
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 ... -
Prey selection along a predators' body size gradient evidences the role of different trait-based mechanisms in food web organization
(PUBLIC LIBRARY SCIENCE, 2023-10-05)An increase in prey richness, prey size and predator trophic position with predator body size has been consistently reported as prime features of food web organization. These trends have been explained by non-exclusive ... -
Publisher Correction: Soil contamination in nearby natural areas mirrors that in urban greenspaces worldwide
(Nature Publishing Group, 2023-04-26)In the version of this article originally published, the current affiliation 25, “CEAZA, Universidad Católica del Norte, Coquimbo, Chile,” initially appeared as the last affiliation, offsetting all author footnotes from ... -
Soil contamination in nearby natural areas mirrors that in urban greenspaces worldwide
(NATURE PORTFOLIO, 2023-03-27)Soil contamination is one of the main threats to ecosystem health and sustainability. Yet little is known about the extent to which soil contaminants differ between urban greenspaces and natural ecosystems. Here we show ... -
Neighbourhood landscape context shapes local species richness patterns across continents
(WILEY, 2023-06)Aim: Recent studies highlight the importance of linking landscape ecology and macroecology for a better understanding of broad-scale biodiversity patterns. The "landscape context effect" denotes that species responses and ... -
Exploring the theoretical and practical implications of eigenbehavior at the intersection of second-order cybernetics and ecosystem management
(Emerald Group Publishing Ltd., 2023-09-11)In this conceptual paper the authors aim to discuss the implications of a second-order cybernetic approach and eigenbehavior in ecosystem management. The authors argue that traditional management practices rely on the ... -
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. ... -
Socially unstable conditions experienced during development prime female Octodon degus to shape the phenotype of their own offspring
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2021-08)Because residents and immigrants from group living species may experience fitness costs associated with permanent changes in group membership, we examined the hypothesis that females experiencing socially unstable or ... -
Socioecological conditions predict degu social instability and provide limited cues to forecast subsequent breeding conditions
(SPRINGER, 2021-05)Permanent changes in group membership may result in detrimental fitness effects on both group residents and immigrants. Factors associated with this form of social instability are rarely documented. We used a 15-year dataset ... -
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 ... -
Global homogenization of the structure and function in the soil microbiome of urban greenspaces
(AMER ASSOC ADVANCEMENT SCIENCE, 2021-07)The structure and function of the soil microbiome of urban greenspaces remain largely undetermined. We conducted a global field survey in urban greenspaces and neighboring natural ecosystems across 56 cities from six ... -
Spatial distribution and interannual variability of coastal fog and low clouds cover in the hyperarid Atacama Desert and implications for past and present Tillandsia landbeckii ecosystems
(SPRINGER WIEN, 2021-10)The hyperarid Atacama Desert coast receives scarce moisture inputs mainly from the Pacific Ocean in the form of marine advective fog. The collected moisture supports highly specialized ecosystems, where the bromeliad ... -
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 ... -
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, ... -
Tomato Cultivars With Variable Tolerances to Water Deficit Differentially Modulate the Composition and Interaction Patterns of Their Rhizosphere Microbial Communities
