Large herbivore grazing and non-native plant invasions in montane grasslands of central Argentina
(Natural Areas Assoc, 2010-04)
Grazing by large herbivores has the potential to facilitate invasion of natural grasslands by non-native plant species. It is expected that both herbivore identity and plant community type modulate the effect. The objective ...
Effects of Urochloa humidicola on Plant Diversity in Native Grasslands in a Neotropical Wetland
Studies on species invasion in wetlands are fundamental to understanding the consequences of the introduction of exotic plants, which are often utilized in grasslands. The loss of native plant diversity is of increasing ...
Soil ecosystem function under native and exotic plant assemblages as alternative states in successional grasslands
Old fields often become dominated by exotic plants establishing persistent community states. Ecosystem function in such novel plant assemblages may differ widely from that in the alternative, native-dominated counterparts. ...
Emergence And Establishment Of Native And Non-native Species In Soils Of Remnant And Converted Highland Grasslands – Southern BrazilEmergência E Estabelecimento De Espécies Nativas E Exóticas Em Solos De Campos Convertidos E Nativos Remanescentes Do Planalto - Sul Do Brasil
(Universidade Estadual de Campinas UNICAMP, 2017)
Community disassembly and invasion of remnant native grasslands under fluctuating resource supply
1. Native vegetation fragments embedded in anthropogenic landscapes are increasingly threatened by land-use intensification. Managing disturbance regimes and nutrient inputs may help maintain species diversity in such ...
Effect of grassland management on soil carbon sequestration in Rondonia and Mato Grosso states, Brazil
(ELSEVIER SCIENCE BV, 2009)
Grassland management affects soil organic carbon (SOC) content and a variety of management options have been proposed to sequester carbon. However, studies conducted in Brazilian pastures have shown divergent responses for ...
CULTIVO DE EUCALYPTUS REDUZ A DIVERSIDADE DA HERPETOFAUNA EM ÁREA DE CAMPO NO SUL DO BRASIL
(Universidade Federal de Santa MariaBRCiências BiológicasUFSMPrograma de Pós-Graduação em Biodiversidade Animal, 2014-02-19)
The expansion of forestation on grassland ecosystems has dramatically changed the landscape, as well as affected the biodiversity and the sustainability of these ecosystems around the world. Grasslands of southern South ...
Natural grasslands in the Chaco. A neglected ecosystem under threat by agriculture expansion and forest-oriented conservation policies
In most tropical and subtropical biomes, conservation strategies are mainly focused on the preservation of forests. However, neotropical dry forest and savanna ecoregions include open habitats that may deserve conservation ...
Long-term monitoring of shrub species translocation in degraded Neotropical mountain grassland
The introduction of plant species is a central topic in restoration ecology research. It is an effective technique to restore degraded ecosystems that present low resilience, such as the rupestrian grasslands. Once ...
Feral horses dung piles as potential windows for alien plants in natural grasslands
Small scale disturbances could act as patches that provide sites for the colonization of competitively inferior species, promoting the establishment of non-native species in some cases. We analyzed the vegetation associated ...
