Leaf traits combinations may explain the occurrence of savanna herbaceous species along a gradient of tree encroachment
(2017-09-01)
In savanna environments, plants have specific leaf traits to deal with high irradiance. These traits allow plants to show high carbon assimilation capacity. However, under encroachment, reduced light availability may act ...
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 ...
Woody plant encroachment constrains regeneration of ground-layer species in a neotropical savanna from seeds
(2022-01-01)
Woody plants have been encroaching into savannas on a global scale. Global climatic changes, along with changes to disturbance regimes, are considered to be the main drivers of this process. Particularly, many formerly ...
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 ...
Soil erosion facilitates shrub encroachment in Patagonian herbaceous steppes
(John Wiley & Sons Ltd, 2021-06)
Previous studies in northeastern Patagonia suggested that, mainly as a consequence of overgrazing by sheep, the herbaceous steppes are being replaced by shrub steppes dominated by Chuquiraga avellanedae as a consequence ...
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) ...
Leaf anatomical traits of non-arboreal savanna species along a gradient of tree encroachment
(Soc Botanica Brasil, 2018-01-01)
In the Brazilian savanna (Cerrado of Brazil), fire suppression has transformed typical savanna formations (TS) into forested savanna (FS) due to the phenomenon of encroachment. Under encroachment, non-arboreal plants begin ...
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 ...
Encroachment of Acacia brevispica and Acacia drepanolobium in semi-arid rangelands of ethiopia and their influence on sub-canopy grasses
(Research Journal of Botony, 2010)
Evolution of argoma shrubland (Ulex gallii Planch.) after clearing and burning treatments in Sierra de Aralar and belate (Navarra)
(2019)
All rights reserved. Shrub encroachment is considered one of the greatest threats in the conservation of pastures, especially in abandoned territories and territories with low stocking density. However, in the Navarra ...
