Abandoned pastures cannot spontaneously recover the attributes of old-growth savannas
(2018-05-01)
Active restoration strategies have been recommended to recover Neotropical savannas in abandoned lands, but no studies have investigated the trajectories and speeds of spontaneous recovery for these systems. Research into ...
Photosynthetic responses of understory savanna plants: Implications for plant persistence in savannas under tree encroachment
(2018-03-01)
Savannas are ecosystems where plants are expected to have leaf-level adaptations conferring tolerance to high irradiances, which characterizes this type of open canopy vegetation. The neotropical savannas of Brazil (Cerrado) ...
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 ...
The effects of tree cover and soil nutrient addition on native herbaceous richness in a neotropical savanna
(2021-01-01)
Exotic grasses and high-nutrient availability are common factors that may limit recovery of herbaceous diversity in derived savannas, while tree encroachment is a threat to diversity in old-growth savannas. To understand ...
Differential seedling establishment of woody plants along a tree density gradient in Neotropical savannas
(Wiley Blackwell Publishing, Inc, 2012-11)
Seedling dynamics are crucial for understanding spatial plant distribution patterns, yet little is known about seedling establishment in Neotropical savannas because empirical studies at the community level are scarce. ...
Seed limitation of woody plants in Neotropical savannas
(Springer, 2012-02)
The failure of seeds to arrive at all suitable sites (seed limitation) greatly affects plant distribution and abundance. In contrast to tropical forests, the degree of seed limitation in Neotropical savannas is unclear ...
