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, ... -
Self-Compatibility Not Associated with Morphological or Genetic Diversity Reduction in Oil-Rewarding Calceolaria Species
(MDPI Multidisciplinary Digital Publishing Institute, 2020-10)One of the most common evolutionary transitions in angiosperms is the reproductive change from outcrossing to selfing, commonly associated with changes in floral biology and genetic diversity. Here, we aim to test whether ... -
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 ... -
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 ... -
Soil bacterial community structure of fog-dependent Tillandsia landbeckii dunes in the Atacama Desert
(SPRINGER WIEN, 2021-09-06)The interplay between plants and soil drives the structure and function of soil microbial communities. In water-limited environments where vascular plants are often absent and only specialized groups of rootless plants ... -
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 ... -
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. ... -
Sources and diffusive air-water exchange of polycyclic aromatic hydrocarbons in an oligotrophic North-Patagonian lake
(Elsevier, 2020-10)Polycyclic aromatic hydrocarbons (PAHs) are semivolatile organic compounds of environmental concern. This study aims to investigate the influence of local sources of anthropogenic PAHs and their air-water exchange fluxes ... -
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 ... -
Species traits and network structure predict the success and impacts of pollinator invasions
(NATURE PUBLISHING GROUP, 2018)Species invasions constitute a major and poorly understood threat to plant-pollinator systems. General theory predicting which factors drive species invasion success and subsequent effects on native ecosystems is particularly ... -
Structure and vulnerability of the multi-interaction network in macrophyte-dominated lakes
(WILEY, 2020)The network approach is crucial to understand how ecosystems are structured and how they will respond to the disturbances (e.g. the current global change). We have recreated the multi-interaction network of a shallow ... -
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 ... -
Taxonomic reassignment of Pseudohaptolina birgeri comb. nov. (Haptophyta)
(Allen Press Inc., 2020-11)The haptophyte genus Pseudohaptolina (formerly Chrysochromulina clade B1-3) currently harbours two species: Pseudohaptolina arctica and Pseudohaptolina sorokinii. In addition, Chrysochromulina birgeri is expected to belong ... -
Temperature modulates Fischerella thermalis ecotypes in Porcelana Hot Spring
(ELSEVIER GMBH, URBAN & FISCHER VERLAG, 2018)In the Porcelana Hot Spring (Northern Patagonia), true-branching cyanobacteria are the dominant primary producers in microbial mats, and they are mainly responsible for carbon and nitrogen fixation. However, little is known ... -
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 ... -
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, ... -
The process of connectivity loss during habitat fragmentation and their consequences on population dynamics
(ELSEVIER SCIENCE BV, 2018)Understanding the processes and consequences of habitat fragmentation is highly relevant since it represents a serious threat to biodiversity. However, fragmentation includes several facets that are difficult to dissect, ... -
The resolution-dependent role of landscape attributes in shaping macro-scale biodiversity patterns
(WILEY, 2019)Aim The aim was to assess whether and to what extent the role of local landscape attributes in shaping macroscopic biodiversity patterns is sensitive to spatial and thematic resolutions of land cover data. Location Sub-Saharan ... -
Time-Based Systems Biology Approaches to Capture and Model Dynamic Gene Regulatory Networks
(ANNUAL REVIEWS, 2021-07-19)All aspects of transcription and its regulation involve dynamic events. However, capturing these dynamic events in gene regulatory networks (GRNs) offers both a promise and a challenge. The promise is that capturing and ...
