The invaders project analyzed the response of a native Neotropical
savanna grass (Trachypogon plumosus) and two African invaders
(Hyparrhenia rufa and Melinis minutiflora) to high CO2, drought,
We studied drought effects on ecosystem functioning in a semiarid
grass-shrub steppe South of Argentina. We designed a 2-year rainfall
manipulation experiment where we decreased water input with rainout ...
The expansion of cattle ranching and the creation of pastures are among the
principal causes of deforestation in South America. This book, Expansao e
trajetorias da pecuaria na Amazonia: Para, Brasil, ...
Our objectives were to analyse the changes in diversity, floristic
composition and plant traits of the major life forms (graminoids and
forbs) in response to nine years of grazing exclosure in five ...
In this study, we analyzed the impact of grazing-induced changes in
species composition and community structure upon the productivity of a
grassland in the Campos region, Uruguay. We compared three ...
Human activities are altering biodiversity and the N cycle globally,
affecting marine and terrestrial carbon cycling. Only a few
specialized bacteria carry out nitrification in terrestrial
The importance of standing dead material, including coarse woody
debris in forests, has been shown to be important in the regeneration
of forests, and critical for maintaining a variety of ecosystem ...
The objective of this study was to determine regional and local
controls of vegetation spatial-heterogeneity in the Patagonian
steppe. We considered two possible factors, rainfall and ovine
This component of the CRN explores the variation in florisitc
diversity in tropical and temperate ecosystems located on the
northernost distribution of the Neotropics. Sampling protocol is based
We tested the biodiversity-productivity hypothesis that states that
increasing species richness results in increasing ecosystem
functioning. We created a richness gradient by removing species in the ...
The data file consists of the numbers of fragments, an index of
bacteria genetic richness, generated from Terminal Restriction Fragment
Length Polymorphism (TRFLP) analysis of grassland soils collected ...
The vegetation affects the soil beneath, and these changes could be
important in arid ecosystems. The patagonian steppe is characterized
by patches of grasses and shrubs. The objective of this study ...
We examined the effect of aboveground diversity on belowground
processes. Our hypothesis is that aboveground diversity produces
long-term effects on soil biota and carbon and nitrogen pools that
We characterize dominant Patagonian species based in several
attributes that influence the ecosystem functioning. Species were
characterized by their potential mineralization, their effects on soil ...
Meteorological data from Rio Mayo, Province of Chubut, Argentina. Rio
Mayo is located at 45 41S and 70 16W and an elevation of
500m. Climatic data is organized daily and bi-hourly. Daily values are ...
