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 ...
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 ...
Characterization of the herbaceous layer in woody thickets of Geoffroea decorticans in central Pampean grasslands
(Gebruder Borntraeger, 2020-08)
Questions: Woody encroachment is a complex ecological phenomenon, which modifies the composition and diversity of species, productivity, carbon storage and cycling, water dynamics, among others. In Argentina’s semiarid ...
Shifting carbon pools along a plant cover gradient in woody encroached savannas of central Argentina
(Elsevier Science, 2014-01)
Woody plant encroachment is a widespread process of land cover change driven by a combination of local land use practices and regional to global environmental changes. Increases in woody plant cover alter the distribution ...
Natural grasslands in the Chaco. A neglected ecosystem under threat by agriculture expansion and forest-oriented conservation policies
(Elsevier, 2015-12)
In most tropical and subtropical biomes, conservation strategies are mainly focused on the preservation of forests. However, neotropical dry forest and savanna ecoregions include open habitats that may deserve conservation ...
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) ...
To chop or not to chop? Tackling shrub encroachment by roller-chopping preserves woody plant diversity and composition in a dry subtropical forest
(2017-10-15)
Shrub encroachment is a frequently observed phenomenon in the arid and semi-arid biomes. In the dry forests of the Argentine Chaco ecoregion that are affected by shrub encroachment, the growing demand for grazing areas has ...
Grazing and neighborhood interactions limit woody encroachment in wet subtropical savannas
(2014-12)
Woody encroachment in savannas is a worldwide concern, and there is growing consensus that anthropogenic activities play a central role in changing tree – grass interactions. We evaluated the influence of livestock grazing ...
Woody plant-cover dynamics in Argentine Savannas from the 1880s to 2000s: The interplay of encroachment and agricultural conversion at varying scales
(Springer, 2015-04)
Woody plant-cover dynamics can alter the provisioning of ecosystem services that humans rely on. However, our understanding of such dynamics today is often limited by the availability of reliable and detailed land-cover ...
