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, ...
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 ...
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 ...
Small eukaryotic phytoplankton communities in tropical waters off Brazil are dominated by symbioses between Haptophyta and nitrogen-fixing cyanobacteria
(NATURE PUBLISHING GROUP, 2018)
Symbioses between eukaryotic algae and nitrogen-fixing cyanobacteria have been recognized in recent years as a key source of new nitrogen in the oceans. We investigated the composition of the small photosynthetic eukaryote ...
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, ...
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 ...
Entrenamiento de handgrip isométrico de alta intensidad en adultos mayores pre-hipertensos y con diagnóstico de hipertensión arterial sistémica etapa I
(Chile. Universidad Mayor, 2020)
Background: Moderate isometric handgrip exercise is an effective tool in the management of systemic hypertension. Aim: To evaluate the effectiveness of a high intensity isometric handgrip exercise protocol for the reduction ...
