Let's learn more about African savannas.②The savann a is a special are a in Afric a and tall grasses grow there. The savann a does not have groups of trees like a forest. It has lots of single trees scattered across the grassland. Acacia trees(金合欢树) grow in the savanna. ...
In savanna systems, Macrotermes termites, through forming spatially explicit mounds with unique woody plant assemblages, emerge as important sources of such heterogeneity. Despite a growing consensus regarding the importance of functional diversity (FD) to ecosystem processes, no study has quantified how ...
Now researchers have teased out some of these factors in an East African savanna.The impala(黑斑羚)eat grasses and trees and is itself eaten by wild dogs and leopards.Impala often munch on a tree called the acacia(金合欢).Some acacia have thorns, and some don't. The researchers found th...
The African continent contains the world's largest area of savanna and around 17 per cent of the world's tropical forests. Savannas alone account for 30 per cent of the primary production from global terrestrial vegetation, underlining the importance of African vegetation. The paper Large Scale Pr...

plants are understorey trees and shrubs in tropical closed forests (57.9%), not the timber trees; in tropical forest regrowth, the most important are scrambling shrubs and farmbush forbs (62.5%); trees and shrubs are important in savanna woodlands (75.6%) and also in the Sahel savanna. ...
Spinescence is an important functional trait possessed by many plant species for physical defence against mammalian herbivores. The development of spinescence must have been closely associated with both biotic and abiotic factors in the geological past,
Modelling the impact of climate change on woody plant population dynamics in South African savanna Background In Southern Africa savannas climate change has been proposed to alter rainfall, the most important environmental driver for woody plants. Woody ... J Tews,F Jeltsch - 《Bmc Ecology》 被...
To create grass that can stand on its own, fold the strip of grass at the base to create a bottom tab. Glue the bottom tab onto the diorama's floor. See Craft: African Savanna Diorama JUNGLE VINES 1Twist crepe paper. Cut 1-inch wide strips of green crepe paper. Twist the entire len...
Therefore, in addition to constituting an important source of nutrients, WFP can be used to help treat and avoid health problems. This study sought to characterize the traditional use of plants considered simultaneously as food and medicine by local specialists in the community of Caeté-Açu, ...
