Evaluation of the Abundance of DNA-Binding Transcription Factors in Prokaryotes
(MDPI, 2020)The ability of bacteria and archaea to modulate metabolic process, defensive response, and pathogenic capabilities depend on their repertoire of genes and capacity to regulate the expression of them. Transcription factors ... -
Relationship between photo-physical and electrochemical properties of D--A compounds regarding solar cell applications. 1. Substituent type effect in photovoltaic performance
(SPRINGER, 2019)Studying the electrochemical characteristics is an important step for determining interactions between molecules and the chemical environment. Moreover, the electrochemical evaluation of dyes is highly needed to establish ... -
Physical-chemical properties of M@Fe3O4 core@shell nanowires (M = Cu, Co, CoO)
(ROYAL SOC CHEMISTRY, 2019)Interest in low dimensional magnetic systems has been growing due to the novel and dramatically differentiated effects of their physical properties, which give them special behaviors and uses in biomedical, environmental ... -
Global ecological predictors of the soil priming effect
(NATURE PUBLISHING GROUP, 2019)Identifying the global drivers of soil priming is essential to understanding C cycling in terrestrial ecosystems. We conducted a survey of soils across 86 globally-distributed locations, spanning a wide range of climates, ... -
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 ... -
Summer phyto- and bacterioplankton communities during low and high productivity scenarios in the Western Antarctic Peninsula
(SPRINGER, 2019)Phytoplankton blooms taking place during the warm season drive high productivity in Antarctic coastal seawaters. Important temporal and spatial variations exist in productivity patterns, indicating local constraints ... -
Seabird and pinniped shape soil bacterial communities of their settlements in Cape Shirreff, Antarctica
(PUBLIC LIBRARY SCIENCE, 2019)Seabirds and pinnipeds play an important role in biogeochemical cycling by transferring nutrients from aquatic to terrestrial environments. Indeed, soils rich in animal depositions have generally high organic carbon, ... -
Microplastic ingestion cause intestinal lesions in the intertidal fish Girella laevifrons
(PERGAMON-ELSEVIER SCIENCE LTD, 2020)We exposed juvenile intertidal fish to different amounts of Poly(styrene-co-divinylbenzene) microplastics in their diet. We fed ten individuals with pellets containing 0.01 g, another ten fish with pellets containing 0.1 ... -
Two novel azaspiracids from Azadinium poporum, and a comprehensive compilation of azaspiracids produced by Amphidomataceae, (Dinophyceae)
(ELSEVIER SCIENCE BV, 2019)Two novel azaspiracids (AZA) with a molecular mass of 869 Da were found in Pacific strains of Azadinium poporum and characterized by tandem mass spectrometry and high resolution mass spectrometry (HRMS). One compound, ... -
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 ... -
Multiple mating is linked to social setting and benefits the males in a communally rearing mammal
(OXFORD UNIV PRESS INC, 2019)Individuals in social species may mate with multiple opposite-sex individuals, including members of the same or different social groups. This variation may be linked to genetic benefits, where multiple mating decreases ... -
Temporal variation in the influence of forest succession on caterpillar communities: A long-term study in a tropical dry forest
(WILEY, 2019)Forest succession can influence herbivore communities through changes in host availability, plant quality, microclimate, canopy structure complexity and predator abundance. It is not well known, however, if such influence ... -
Non-trophic interactions strengthen the diversity-functioning relationship in an ecological bioenergetic network model
(PUBLIC LIBRARY SCIENCE, 2019)Ecological communities are undeniably diverse, both in terms of the species that compose them as well as the type of interactions that link species to each other. Despite this long recognition of the coexistence of multiple ... -
Legalism and creativity: tax non-compliance in the eyes of the economic elite
(ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD, 2019)This paper analyzes elite tax compliance from a sociological perspective in order to examine how different tax behaviors are justified or how they embody different taxpayers' subjectivities. Drawing from the case of Chile ... -
Business Power and the Minimal State: The Defeat of Industrial Policy in Chile
(ROUTLEDGE JOURNALS, TAYLOR & FRANCIS LTD, 2019)Chile has maintained a limited industrial policy for nearly three decades. Policy resilience during the 2000s and 2010s is especially puzzling given the political and economic context: three Socialist-led administrations; ... -
From 'Green Laggard' to Regional Leader: Explaining the Recent Development of Environmental Policy in Chile
(WILEY, 2019)Environmental policy in Chile has developed rapidly in recent years, and the country has become a regional leader in renewable energy, climate change policy, recycling, and nature conservation. This contrasts with the ... -

Are foreign-born researchers more innovative? Self-selection and the production of knowledge among PhD recipients in the USA
(SPRINGER HEIDELBERG, 2019)When analyzing knowledge production, the evidence suggests that within the USA, foreign-born researchers exhibit more productivity than their domestic counterparts. Previous literature indicates that productivity differences ... -
Do Young People Adapt Their Prosocial Behaviour to That of Their Peers? An Experimental Exploration
(SAGE PUBLICATIONS LTD, 2019)Moral decisions - that is, decisions that consider the consequences for the welfare of others - can be highly inconsistent across contexts. Here, we explore whether the altruism of young people is related to their willingness ...
