How does the whistling thorn survive in the savanna?
Because of the heat the tree must find ways to conserve moisture. Their leaves have evolved into many tiny leaflets (pinnae) which can turn to absorb sunlight, or avoid it and reduce transpiration. The many leaflets are also beneficial when animals graze on them.
What eats a whistling thorn in the savanna?
Whistling thorn is the dominant tree in some areas of upland East Africa, sometimes forming a nearly monoculture woodland, especially on “black cotton” soils of impeded drainage with high clay content. It is browsed upon by giraffes and other large herbivores.
How long does the whistling thorn live?
Most wattles are short-lived and will live no longer than 10-20 years but a few are long-lived (up to 200-300 years).

How does the umbrella thorn acacia adapt to the savanna?
Umbrella Thorn Acacia has many adaptions to survive in the savanna. First, it has a deep taproot so that it could get water during the dry season. Then Acacia’s small leaves prevent water loss. And Acacia’s umbrella-shaped tops enables the leaves to catch as much sunlight as possible.
Why is the acacia tree important to the savanna?
The acacia and baobab trees are common in African savannas. In order for the grasses to survive the dry season and the periodic fires, they have developed an adaptation that allows them to grow quickly when there is adequate water. Then when water becomes scarce, the grasses turn brown to limit water loss.
What are the functions of thorns and spines?
The predominant function of thorns, spines and prickles is deterring herbivory in a mechanical form.

Not all functions of spines or glochids are limited to defense from physical attacks by herbivores and other animals.
