The Bonobo (Pan paniscus) is a great ape, found only in the forests of the Democratic Republic of Congo. It is an endangered species and estimates of population range between 29,500 to 50,000.
Groups of bonobos found in different areas of the dense forest have been extensively studied by scientists from around the world. One institute that has conducted many behavioural studies is the Max Planck Institute for Evolutionary Anthropology. The scientists have habituated a group of bonobos in the Salonga National Park by almost daily visits over five years. Although the national park is protected, there are increasing threats from poaching and hunting for the commercial bushmeat trade.
The Dragon tree (Dracaena draco) is a perennial plant of slow growth, which can reach about 20m in height, with an umbel shaped canopy. The tree is a native species of Madeira, the Canary Islands and Cape Verde. It grows extremely slowly, taking approximately 10 years to reach about 2-3 feet.
In Madeira it is rare to find it in its natural state; instead, it is very much used for ornamental purposes. In the past it was largely exploited for its reddish sap referred to as “dragon blood”, which was used as domestic medicine, as a dyeing product and as varnish. There are now very few native Dragon trees in Madeira.
