Modelling competitive ability of neotropical savanna grasses: Simulation of shading and drought impacts on biomass production
(Ecological Informatis 13: 57-69, 2013)
In this paper, we develop a technique to model the spatial distribution of shoots along vertical and horizontal dimensions of a plant community. We use it to simulate the growth of a tropical savanna near the city of ...

Coupling soil water and shoot dynamics in three grass species: A spatial stochastic model on water competition in Neotropical savanna
(Ecological Modelling 220: 2734 - 2743, 2009-10-24)
Savannas are ecosystems known for their high environmental and economic value. They cover at least 20% of the global land surface and, in some cases, can act as a boundary between tropical rainforest and deserts.Water is ...

Fire in neotripical savannas
(Encyclopedia of life support systems (EOLSS), developed under the auspices of the UNESCO, EOLSS publishers, Oxford ,UK, [http://www.eolss.net], 2007)
This chapter reviews the main characteristics of tropical savannas and their interactions with fire, a main factor involved in the dynamics of these ecosystems. Burning in savannas generally takes place by the end of the ...
Spatial heterogeneity, land use and conservation in the cerrado region of Brazil
Aim This paper presents a spatial classification of the environmental and ecological diversity of the cerrado region of Brazil, as well as an appraisal of the levels of conversion to agriculture and of the extent of land ...
Modelling the effects of fire and competition on the dynamics of neotropical savannas: from plants to community
Savannas are one of the most extensive biomes of the world and are subject to intense pressures due to large human populations using this ecosystem, even though it is characterized by low crop yields and poor nutritional ...
Seed dispersal in Palicourea rigida H.B.K, a common treelet species from neotropical savannas
The dispersal system of Palicourea rigida (Rubiaceae), a common woody species of neotropical savannas, was studied in a seasonal Venezuelan savanna. Production and consumption of fruits, dispersal agents, feeding ...
