The functioning of the forest ecosystem is complex and often not easy to understand. This includes the mycorrhiza, the living community between plants and fungi. This symbiosis is illustrated with an educational film of the nationalparks Bavarian Forest and Šumava.

Nat Geo - Desert elephant and its characteristics - BBC
Desert elephants are not a distinct species of elephant but are African bush elephants (Loxodonta africana) that have made their homes in the Namib and Sahara deserts. It was believed at one time that they were a subspecies of the African bush elephant but this is no longer thought to be the case. Desert-dwelling elephants were once more widespread in Africa than they are now and are currently found only in Namibia and Mali. They tend to migrate from one waterhole to another following traditional routes which depend on the seasonal availability of food and water. They face pressure from poaching and from changes in land use by humans.
