The recovery rates of secondary savannas in abandoned pastures are poorly explained by environmental and landscape factors
(2020-01-01)
Question: Assessing the natural regeneration potential of degraded savannas is a crucial step in restoration planning, since that assessment will define the need for and costs of active intervention. Predicting natural ...
Soil dehydrogenase in a land degradation-rehabilitation gradient: observations from a savanna site with a wet/dry seasonal cycle
(Universidad de Costa Rica, 2009)
Changes in irradiance and soil properties explain why typical non-arboreal savanna species disappear under tree encroachment
(Csiro Publishing, 2016-01-01)
Savanna vegetation maintains its openness and its diverse plant composition because of frequent fire events; however, when these are suppressed, encroachment is caused by increases in the tree density. In the neotropical ...
Tree encroachment into savannas alters soil microbiological and chemical properties facilitating forest expansion
(2016-10-01)
Forests have been expanding over typical savanna sites for the past 3000 years in the Neotropics. Such invasion can produce a series of environmental modifications on typical savanna; however, it remains unclear how ...
Soil-vegetation relationships in cerrado (Brazilian savanna) and semideciduous forest, Southeastern Brazil
(Kluwer Academic PublDordrechtHolanda, 2002)
Effect of fires on soil nutrient availability in an open savanna in Central Brazil
(SPRINGER, 2010)
Fire is common in savannas but its effects on soil are poorly understood. We analyzed long-term effects of fire on surface soil of an open Brazilian savanna (campo sujo) in plots submitted to different fire regimes during ...
