Functional roles of termites in savanna ecosystems

open access: yes, 2009
Bernd Freymann investigated autecological and ecosystem-wide aspects of the functional role of termites (Insecta, Isoptera) in decomposition processes in Serengeti National Park, Tanzania, on different spatial and temporal scales. The eusocial termites

EFFECTS OF FIRE AND HERBIVORY ON THE STABILITY OF SAVANNA ECOSYSTEMS [PDF]

open access: yesEcology, 2003
Savanna ecosystems are characterized by the co-occurrence of trees and grasses. In this paper, we argue that the balance between trees and grasses is, to a large extent,determined by the indirect interactive effects of herbivory and fire. These effects are based on the positive feedback between fuel load (grass biomass) and fire intensity.

Frequent burning promotes invasions of alien plants into a mesic African savanna [PDF]

open access: yes, 2010
Fire is both inevitable and necessary for maintaining the structure and functioning of mesic savannas. Without disturbances such as fire and herbivory, tree cover can increase at the expense of grass cover and over time dominate mesic savannas ...

Remote sensing of savanna woody species diversity: A systematic review of data types and assessment methods

open access: yesPLoS ONE, 2022
Despite savannas being known for their relatively sparse vegetation coverage compared to other vegetation ecosystems, they harbour functionally diverse vegetation forms. Savannas are affected by climate variability and anthropogenic factors, resulting in

Dynamics of Sudanian savanna-woodland ecosystem in response to disturbances [PDF]

open access: yes, 2007
Grazing, fire and selective tree cutting are major disturbances shaping species diversity and productivity in savanna-woodland ecosystems. Their effects, however, are highly variable and poorly understood.
