at the water hole

In the savannah, water holes are incredibly important features of the landscape, especially during the dry season. The seasonal or permanent pools of water, fed by rivers or aquifers, provide much-needed hydration for all animals of the savannah, sometimes drawing them in from many miles away.Predator and prey alike gather to drink, and these connections keep the all-important savannah food web healthy. With all the animals gathering in one place, the predators have enough food but kill only what they need, which monitors the population naturally. Meanwhile the prey species are able to take a good long drink before moving on to their next destination.…

what species inhabit the african savannah?

The savannah environment is a huge expanse of wide-open grassland that is home to a web of incredible plants and animals. Formed exclusively around the tropics, savannahs are characterised by just enough rainfall in the wet season to enable plants to flourish, yet not enough for a rainforest, and almost arid conditions in the dry season, but not dry enough to form a desert. The plants and animals that live here have developed amazing means of coping with this extreme environment.Around the world, savannahs are known by different names; in Asia they are ‘steppes’, they are ‘prairies’ in North America, and in Australia they are ‘rangelands’. Usually only African grasslands are given the name ‘savannah’, and one of the most famous is the Serengeti Plains in Tanzania. This ecosystem is…

life on the ground

Prevalence of grassThe fact that the laterite soil layer prevents trees from taking root is what favours the prevalence of so many grasses, which have much shorter root systems.LateriteSeason upon season of rain and drought have caused the layers below the humus to become incredibly hard. The soil is so cemented that long tree roots are unable to penetrate it.HorizonsThe flow of nutrients head downwards through the soil, which creates horizons, each one differing in composition from the one above it. Below these, the bedrock sits.HumusThe thinnest, uppermost layer in the soil profile is known as humus. It’s made of the organic matter from decaying plants and animals, and provides vegetation with nutrients.Distinctive red soilDuring the wet season, intense leaching occurs where water draws out nutrients and chemical compounds from…

what are asperatus clouds?

The last time a new type of cloud was officially recognised by the UN’s World Meteorological Organization was in 1951, but these choppy seas in the sky could be next.After being unable to identify the clouds from photos sent in by sky watchers all over the world, the Cloud Appreciation Society has proposed that they should be officially classified as asperatus clouds, from the Latin word for ’roughened‘. For this to happen, the cause of the cloud has to be identified first. Although their formation is not yet entirely understood, some experts believe they form under the same conditions as mammatus clouds, which look as though they have a series of pouches hanging below them. These occur when ice crystals in the clouds sink, but are too large to evaporate…

what are woodlice?

Woodlice are so tolerant to heavy metals that they can be used as pollution bioindicators (© WIKI; Getty)The next time you move something in the garden and see a woodlouse scuttling out from underneath, remember that these little guys are in fact isopod crustaceans! They’re more closely related to crabs and lobsters than ants and spiders. Although they’re landlubbers, one trait woodlice share with their aquatic cousins is that they use gills to breathe.They like to live in moist, dark places where there’s plenty of decaying material to eat. Their bodies are made up of armoured segments of an exoskeleton that allow them to roll up into balls when threatened, hence the nickname ‘pill bug’. As they grow, woodlice need to shed their skin. This happens in two separate stages;…
