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 ...
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 ...
Reproductive phenology of two co-occurring Neotropical mountain grasslands
(2018-01-01)
Aim: Climate tends to explain phenological variations in tropical ecosystems. However, water availability and nutrient content in soil strongly affect plant communities, especially those on old, climatically buffered, ...
Enhancement of palatable perennial grasses by disturbance and seed addition in degraded native grasslands of the dry pampas in Central Argentina
(Taylor & Francis, 2020-05-07)
Land use has changed the original composition of the natural grasslands in the dry pampas of central Argentina, in detriment of palatable perennial grasses (PPG). Long-term elimination of anthropogenic disturbances has not ...
Restoring Brazilian savanna ground layer vegetation by topsoil and hay transfer
(Wiley-Blackwell, 2018-01-01)
Tropical grassy biomes have been widely neglected for conservation and, after unplanned land use conversion, ecological restoration becomes urgent. The majority of interventions have been based on the misapplication of ...
Natural grasslands in the Chaco. A neglected ecosystem under threat by agriculture expansion and forest-oriented conservation policies
(Elsevier, 2015-12)
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 ...
Grasslands and Open Savannas of the Dry Chaco
(Elsevier, 2019)
The Dry Chaco is mostly known as a forested ecosystem. However it includes natural grasslands, savannas, scrublands, and wetlands. With one of the highest global deforestation rates in the last two decades and only 12% of ...
More Stable Productivity of Semi Natural Grasslands than Sown Pastures in a Seasonally Dry Climate
(2013-06-11)
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 ...
Maintenance of wetland plant communities: the role of the seed bank in regeneration of native plants
(Sociedade Botânica do Brasil, 2021-07-05)
Exotic grasses have been introduced into wetlands and can compete with native plants due to their high tolerance of flood and dry periods. Flooding can facilitate seed dispersal of exotic species and reduce the diversity ...
