Short-term plant community response to grassland management intended to improve forage quality for the endangered Pampas deer
(Elsevier, 2019-08)
The Pampas deer is a medium-sized neotropical cervid whose population has been affected by the advancement of the agricultural frontier, poaching and depredation by introduced species. As a consequence, the population of ...
Determinants of grassland primary production in seasonally-dry silvopastoral systems in Central America
(2014-06)
Grassland primary productivity is the function that underpins the majority of the fodder production in cattle-rearing silvopastoral farms. Hence, understanding the factors that determine grassland productivity is critical ...
Impact of Grazing Intensity and Seasons on Greenhouse Gas Emissions in Tropical Grassland
(2017-06-01)
Greenhouse gases (GHG) can be affected by grazing intensity, soil, and climate variables. This study aimed at assessing GHG emissions from a tropical pasture of Brazil to evaluate (i) how the grazing intensity affects the ...
An assessment of the Important Bird Areas (IBAs) of southern Paraguayan grasslands
(Cambridge Univ Press, 2021-06-01)
We present an assessment of the Southern Paraguayan Grasslands using Important Bird Areas (IBAs) located in a grassland landscape mosaic. Eleven IBAs in southern Paraguay were evaluated 10 years after their designation, ...
Does fire induce flowering in Brazilian subtropical grasslands?
(Wiley-Blackwell, 2014-10-01)
QuestionsWe aimed to analyse the effect of fire on flowering in subtropical grasslands, by addressing the following questions: will fire history affect flowering? If yes, do fire feedbacks influence flowering or is it just ...
Role of fire on patagonian grasslands: Changes in aboveground vegetation and soil seed bank
(Nova Science Publishers, 2010)
Grasslands are ecosystems dominated by herbaceous and woody vegetation, whose structure is determined by fire, grazing, and drought. Although these structuring factors determine the natural dynamics of grasslands, their ...
More stable productivity of semi natural grasslands than sown pastures in a seasonally dry climate
(2015-01-27)
In the Neotropics the predominant pathway to intensify productivity is generally thought to be to convert grasslands to
sown pastures, mostly in monoculture. This article examines how above-ground net primary productivity ...
A research agenda for the restoration of tropical and subtropical grasslands and savannas
(2021-04-01)
Despite growing recognition of the conservation value of grassy biomes, our understanding of how to restore biodiverse tropical and subtropical grassy biomes (grasslands and savannas; TGB) remains limited. Several tools ...
