The influence of soil age on ecosystem structure and function across biomes
(Chile. Universidad Mayor, 2020)The importance of soil age as an ecosystem driver across biomes remains largely unresolved. By combining a cross-biome global field survey, including data for 32 soil, plant, and microbial properties in 16 soil chronosequences, ... -
Soil microbial abundance and activity across forefield glacier chronosequence in the Northern Patagonian Ice Field, Chile
(Chile. Universidad Mayor, 2020)In recently deglaciated soils, microbial organisms drive soil transformations by increasing carbon (C) and nitrogen (N) pools while depleting available phosphorous (P), thus improving plant colonization and soil development. ... -
Latitudinal patterns in the diet of Andean condor (Vultur gryphus) in Chile: Contrasting environments influencing feeding behavior
(Chile. Universidad Mayor, 2020)Human-dominated environments alter the availability and quality of resources for many species, especially for scavengers that have large home ranges and plastic foraging behaviors that enable them to exploit novel resources. ... -
Exploring Perceived Well-Being from Urban Parks: Insights from a Megacity in Latin America
(Chile. Universidad Mayor, 2020)Urbanization has impacted biodiversity and ecosystems at a global scale. At the same time, it has been recognized as a driver of the physical and emotional gap between humans and nature. The lack of direct contact with ... -
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 ... -
Eco-hydrological Functions in Forested Catchments of Southern Chile
(Springer New York, 2020-03)Ecosystem functions in forests can vary significantly after disturbance, depending on changes in vegetation structure during succession and soil biophysical characteristics. We examined streamflow regulation, water storage ... -
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 ... -
Monitoring the occurrence of microplastic ingestion in Otariids along the Peruvian and Chilean coasts
(Elsevier Inc., 2020-04)Repeated reports of microplastic pollution in the marine pinniped diet have emerged in the last years. However, only few studies address the drivers of microplastics presence and the potential implications for monitoring ... -
Geographical origin determines responses to salinity of Mediterranean caddisflies
(Public Library of Science, 2020-01-13)Many freshwater ecosystems worldwide, and particularly Mediterranean ones, show increasing levels of salinity. These changes in water conditions could affect abundance and distribution of inhabiting species as well as the ... -
Remnants of native forests support carnivore diversity in the vineyard landscapes of central Chile
(Cambridge University Press, 2018-03)Carnivores play an important role in ecosystem functioning as apex predators. However, most carnivore species are threatened or have been extirpated in human-dominated landscapes. The Mediterranean region of central Chile ... -
On the proportional abundance of species: Integrating population genetics and community ecology
(Nature Publishing Group, 2017)The frequency of genes in interconnected populations and of species in interconnected communities are affected by similar processes, such as birth, death and immigration. The equilibrium distribution of gene frequencies ... -
Macroecological factors shape local-scale spatial patterns in agriculturalist settlements
(The Royal Society, 2017)Macro-scale patterns of human systems ranging from population distribution to linguistic diversity have attracted recent attention, giving rise to the suggestion that macroecological rules shape the assembly of human ... -
Potential distribution model of Leontochir ovallei using remote sensing data
(UNIV POLITECNICA VALENCIA, EDITORIAL UPV, 2019)Predicting the potential distribution of short-lived species with a narrow natural distribution range is a difficult task, especially when there is limited field data. The possible distribution of L. ovallei was modeled ... -
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 ... -

(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 ...
