About the Author
Dr. Marc van Roosmalen
Dr. Marc G.M. van Roosmalen (born June 23, 1947) is a Dutch-Brazilian primatologist/ecologist/rainforest conservationist. He was elected as one of the “Heroes for the Planet” by Time magazine in 2000. His research has led to the identification of several new monkey species, as well as some other large-bodied mammals, and woody plants from the Amazon basin. Aside of science writer, he is also an activist in the protection of the Brazilian rainforest. In 1997, Marc was awarded the honor of officer in the Order of the Golden Ark by HRH Prince Bernhard of the Netherlands. He studied biology at the Universities of Amsterdam and Utrecht and did four years of doctoral fieldwork (1976-1980) studying the ecology of the red-faced black spider monkey (Ateles paniscus) in the (then) pristine interior of Suriname. ln 1983/84, he conducted Post-doc fieldwork on plant-animal coevolution in French Guiana. Meanwhile, he published A Field Guide to the Fruits of the Guianan Flora, until today widely considered a standard work. In 1986, the Brazilian Ministry of Science and Technology hired him at the National Institute of Amazon Research in Manaus-AM, to extend his 1985 fruit catalogue to the whole Amazon. Marc considers Alfred Russel Wallace a 19th-century “Hero for the Planet” and is an advocate of Wallace’s “river barrier” hypothesis saying that the major rivers of the Amazon basin do serve as geographical barriers that create separate genetically distinct evolutionary regions.
