Amazonian colonization from the Atlantic Forest: New perspectives on the connections of South American tropical forests

Molecular Ecology, 2023
AbstractAn open and dry vegetation belt separates Amazonia (AM) and the Atlantic Forest (AF). Evidence from palaeoclimatic and phylogenetic studies suggests past connections between these forests during cycles of increased humidity through the formation of forest corridors.

Higher fire frequency impaired woody species regeneration in a south-eastern Amazonian forest

Journal of Tropical Ecology, 2020
AbstractUnderstorey wildfires harm tropical forests by affecting natural regeneration, but the trajectories of fire-disturbed forests after disturbance are poorly understood. To fill this gap, we conducted experimental burns in a transitional forest between the Amazon forests and the Brazilian Savanna (Cerrado) and investigated their effects on plant ...

Primate Population Densities in Three Nutrient-Poor Amazonian Terra Firme Forests of South-Eastern Colombia

Folia Primatologica, 2005
We censused primate populations at three non-hunted ‘terra firme’ forests of south-eastern Colombian Amazonia. The aggregate biomass densities of diurnal primates at all sites were amongst the lowest recorded for any non-hunted forest in western Amazonia and elsewhere in the Neotropics.

Monitoring carbon assimilation in South America's tropical forests: Model specification and application to the Amazonian droughts of 2005 and 2010

Remote Sensing of Environment, 2012
Abstract Net primary production (NPP) is a key variable for monitoring and understanding the impacts of environmental change on ecosystems and for generating realistic global and regional carbon budgets. In this paper we present a regional algorithm (RATE) for automatically monitoring the rate of carbon fixation (as measured by NPP) of tropical ...

Identity of Rhammatocerus schistocercoides (Rehn, 1906) forms south and north of the Amazonian rain forest and new hypotheses on the outbreaks determinism and dynamics

1998
Brazil, Colombia and Venezuela have, for several years, been facing severe outbreaks in species belonging to the genus #Rhammatocerus#. This genus is in need of revision and until now it was not certain that the populations involved North and South of the amazonian rain forest belonged to the same species or not.
