Article
Full-text available
The role of soil biodiversity in regulating multiple ecosystem functions is poorly understood, limiting our ability to predict how soil biodiversity loss might affect human wellbeing and ecosystem sustainability. Here, combining a global observational study with an experimental microcosm study, we provide evidence that soil biodiversity (bacteria,...

p>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 using the maximum entropy approach. This species has a very restricted distribution along the hyperarid coastal desert in northe...

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, biotic communities, and soil conditions, and evaluated the apparent soil priming effect using 13C-glucose labeling. Here we show...

Unlike plants and vertebrates, the ecological preferences, and potential vulnerabilities of soil invertebrates to environmental change, remain poorly understood in terrestrial ecosystems globally. We conducted a cross‐biome survey including 83 locations across six continents to advance our understanding of the ecological preferences and vulnerabili...
Article
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 and soil protection functions in small catchments covered by evergreen temperate rain forests, developed over volcanic ash soil...

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 of how and why belowground biodiversity (bacteria, fungi, protists, and invertebrates) may change as soils develop over centuries...
Article
Full-text available
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 in summer all over the CAO. We report for the first time the structure of bacterial communities in this brine. They are composed o...
Article
Full-text available
During soil development bacteria and fungi can be differentially affected by changes in soil biogeochemistry. Since the chemistry of parent material affects soil pH, nutrient availability, and indirectly litter quality, we hypothesize that parent material has an important influence on microbial community patterns during long-term soil development....

This paper reports a quantitative survey of the composition, diversity and structure of the plant communities on six islands of Uyuni and Coipasa salt lakes (Bolivia). Plant communities on each island were examined via the use of 10 transects, along which species richness and abundance were recorded. Seventy-one species were found in total, represe...

Background/Question/Methods Today, over half of humanity lives in cities and the expansion of urban areas is considered one of the greatest threats to biodiversity. Urbanization, negatively affects bird’s richness, abundances and reproduction because it constitutes a drastic habitat modification, and enhance inhospitable environment for many specie...
Article
Multiple ecological factors are known to drive variation in social behavior. However, group-living in some species appears to be highly conserved, suggesting a phylogenetic influence. In this study, we evaluated both scenarios using intraspecific and interspecific comparisons across octodontid rodents. We first examined 2 different populations of A...
Conference Paper
Background/Question/Methods Cloud cover is a major and nearly permanent feature (80% persistence) of the eastern Pacific Ocean in the arid and semiarid continental margin of South America. The cloud field is maintained at a fixed elevation (above 600 m) by a thermal inversion, providing the main or the only source of humidity for a chain of highl...
Conference Paper
Background/Question/Methods Nitrogen (N) and Phosphorus (P) are major cellular components in consumer organisms and, limitations in their availability and accessibility can strongly affect growth and development, as well as life history strategies and population dynamics of consumer species. In environments where periodic disturbances induce form...

2014). Molecular phylogenetics of mouse opossums: new findings on the phylogeny of Thylamys (Didelphi-morphia, Didelphidae) — Zoologica Scripta, 43, 000–000. The mouse opossums of the genus Thylamys constitute a group of species mainly adapted to open xeric-like habitats and restricted to the southern portion of South America. We used molecular dat...

The mouse opossums of the genus Thylamys constitute a group of species mainly adapted to open xeric-like habitats and restricted to the southern portion of South America. We used molecular data (mitochondrial and nuclear sequences) to evaluate the phylogenetic and biogeographical relationships of all currently known living species of the genus, rec...
Conference Paper
Background/Question/Methods What factors drive the observed changes in the number of coexisting species across different spatial and temporal scales? This is a fundamental, albeit vexing, question in ecology. Most answers to this question emphasize the role of abiotic factors (e.g., area, temperature, energy) as drivers of diversity patterns. How...
Article
An active Trypanosoma cruzi transmission cycle maintained by wild rodents in the Andean valleys of Cochabamba Bolivia is described. Wild and domestic Triatoma infestans with 60% infection with T. cruzi were found and was evidenced in 47.5% (rodents) and 26.7% (marsupial) by parasitological and/or serologycal methods. Phyllotis ocilae and the marsup...
