Phytolith Assemblages in Grasses Native to Central Argentina
(Oxford University Press, 2004-12)
Background and Aims Phytolith reference collections are a prerequisite for accurate interpretation of soil phytolith assemblages aimed at reconstructing past vegetation. In this study a phytolith reference collection has ...
Fire cues and germination of invasive and native grasses in the Cerrado
(Soc Botanica Brasil, 2020-01-01)
Fire-related cues may enhance seed recruitment in flammable ecosystems and differences in fire-germination responses of invasive vs. native species can drive the invasion process. We evaluated the effects of heat shock and ...
Invasive exotic grasses and seed arrival limit native species establishment in an old-field grassland succession
(Springer, 2012-12)
Plant communities developing in abandoned semi-natural areas are being increasingly dominated by invasive exotic species. How these 'novel residents' affect re-colonisation by native perennial species, a process generally ...
How does fire affect germination of grasses in the Cerrado?
(2020-01-01)
Fire is a frequent disturbance in the Cerrado and is one of the major factors affecting vegetation structure and diversity. Fire events open gaps within the herbaceous layer and increase temperature fluctuation in the soil ...
Mapeamento das áreas de ocorrência de infestação do Eragrostis Plana Nees (capim annoni) com sensoriamento remoto: estudo de caso em Santana do Livramento/RS/ Brasil
(Universidade Federal de Santa MariaBrasilGeografiaUFSMPrograma de Pós-Graduação em GeografiaCentro de Ciências Naturais e Exatas, 2017-08-23)
Eragrostis Plana Nees (Capim annoni) is an invasive species originating from the African continent that has caused numerous environmental and socioeconomic damages, mainly in parts of the Bioma Pampa. Several studies have ...
Green manure cover effects on restoration success in Southeast Atlantic Forest biome
(Ipef-inst Pesquisas Estudos Florestais, 2022-01-01)
Active restoration techniques, such as direct sowing, is an important strategy to benefit forest structure formation and to inhibit the exotic grasses invasion, which is an impediment to many restoration projects. The use ...
Variations in chemical composition associated with tissue aging in palatable and unpalatable grasses native to central Argentina
(Elsevier, 2005-02)
Tissue aging in unpalatable grasses appears to be associated with a rapid decay in nutritional value because grazers usually start to avoid them at early stages of maturity. The objective of the present study was to determine ...
Tree-grass interactions for N in Nothofagus antarctica silvopastoral systems: evidence of facilitation from trees to underneath grasses
(Springer, 2014-06)
Nothofagus antarctica forests in south Patagonia are usually used as silvopastoral systems but how grasses and trees compete for specific resources, such as nitrogen in these systems is unknown. To understand interactions ...
Colonization of native Andean grasses by arbuscular mycorrhizal fungi in Puna: A matter of altitude, host photosynthetic pathway and host life cycles
(Wiley Blackwell Publishing, Inc, 2012-08)
The relationships of altitude, host life cycle (annual or perennial) and photosynthetic pathway (C3 or C4) with arbuscular mycorrhiza (AM) root colonization were analysed in 35 species of Andean grasses. The study area is ...
