(NATURE PORTFOLIO, 2021-01)The future challenges and potential opportunities of robotics and autonomous systems in urban ecosystems, and how they may impact biodiversity, are explored and prioritized via a global horizon scan of 170 experts. Technology ... -
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. ... -
Plant ecological genomics at the limits of life in the Atacama Desert
(NATL ACAD SCIENCES, 2021-11-16)The Atacama Desert in Chile-hyperarid and with high-ultraviolet irradiance levels-is one of the harshest environments on Earth. Yet, dozens of species grow there, including Atacama-endemic plants. Herein, we establish the ... -
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 ... -
Effect of intersystem crossing rates and optical illumination on the polarization of nuclear spins close to nitrogen-vacancy centers
(AMER PHYSICAL SOC, 2021-03-27)Several efforts have been made to polarize the nearby nuclear environment of nitrogen-vacancy (NV) centers for quantum metrology and quantum information applications. Different methods showed different nuclear spin ... -
Spin-lattice dynamics of surface vs core magnetization in Fe nanoparticles
(AIP Publishing, 2021-07-05)Magnetization of clusters is often simulated using atomistic spin dynamics for a fixed lattice. Coupled spin-lattice dynamics simulations of the magnetization of nanoparticles have, to date, neglected the change in the ... -
Sensing Electrochemical Signals Using a Nitrogen-Vacancy Center in Diamond
(MDPI, 2021-02)Chemical sensors with high sensitivity that can be used under extreme conditions and can be miniaturized are of high interest in science and industry. The nitrogen-vacancy (NV) center in diamond is an ideal candidate as a ... -
Viticultural Performance of Hybrids and Vitis vinifera Varieties Established in Annapolis Valley (Nova Scotia)
(MDPI, 2021-09)Cold-hardy interspecific hybrid grapes (CIHG) are well adapted to the Annapolis Valley edaphoclimatic conditions. The main characteristics of CIHG are the high bud hardiness tolerance to winter frost, the short growing ... -
Nutritional status differentially affect yield and must composition of hybrids and V. vinifera varieties established under cold climate conditions
(ESTACAO VITIVINICOLA NACIONAL, 2021-09)Nova Scotia is characterized by cold climate and acidic soils and high organic matter for viticultural development. There is little scientific information available about the nutritional management of grapevine varieties ... -
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 ... -
Effect of exogenous lipids on cryotolerance of Atlantic salmon (Salmo salar) spermatozoa
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2021-02)The development of semen cryopreservation strategies is necessary to improve the semen storage technologies of species of great commercial interest for aquaculture. Recent studies demonstrate that lipids play an important ... -
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 ... -
Simulations of primary damage in a High Entropy Alloy: Probing enhanced radiation resistance
(PERGAMON-ELSEVIER SCIENCE LTD, 2021-07)High Entropy Alloys (HEA) attract attention as possible radiation resistant materials, a feature observed in some experiments that has been attributed to several unique properties of HEA, in particular to the disorder-induced ... -
Nutritional status and sweet taste preference in Chilean adults
(ARCHIVOS LATINOAMERICANOS NUTRICION, 2020-12)El dramático aumento de la prevalencia e incidencia de la obesidad sugiere que factores ambientales y cambios en el estilo de vida contribuyen de forma importante a su tendencia epidémica. En humanos, se han reportado ... -
Enhanced Activity of Exportin-1/CRM1 in Neurons Contributes to Autophagy Dysfunction and Senescent Features in Old Mouse Brain
(HINDAWI LTD, 2021-08-16)Brain aging is characterized by dysfunctional autophagy and cellular senescence, among other features. While autophagy can either promote or suppress cellular senescence in proliferating cells, in postmitotic cells, such ... -
Seasonal precipitation in south-central Chile: Trends in extreme events since 1900
