German-Dutch zoologist and biogeographer
Max Carl Wilhelm Weber van Bosse or Max Wilhelm Carl Weber (5 December 1852 – 7 February 1937) was a German-Dutch zoologist and biogeographer.
Weber studied at the University of Bonn, then at the Humboldt University in Berlin with the zoologist Eduard Carl von Martens (1831–1904). He obtained his doctorate in 1877. Weber taught at the University of Utrecht then participated in an expedition to the Barents Sea. He became Professor of Zoology, Anatomy and Physiology at the University of Amsterdam in 1883. In the same year he received naturalised Dutch citizenship.
His discoveries as leader of the Siboga Expedition led him to conclude that Wallace's Line was placed too far to the west. His studies, along with others, led to a series of alternative lines to be proposed to delimit two major biogeographic realms, the Australasian realm and the Indomalayan realm. These lines were based on the fauna and flora in general, including the mammalian fauna. Later, Pelseneer published an influential paper on this topic, in which he proposed to call his preferred limit Weber's Line, to honour Weber's contributions in that field. As is the case with plant species, faunal surveys revealed that for mollusks and most vertebrate groups Wallace’s line was not the most significant biogeographic boundary. The Tanimbar Island group, and not the boundary between Bali and Lombok, appears to be the major interface between the Oriental and Australasian regions for mammals and other terrestrial vertebrate groups.
With G.A.F. Molengraaff, Weber gave names to the Sahul Shelf and the Sunda Shelf in 1919.
Weber became member of the Royal Netherlands Academy of Arts and Sciences in 1887.
Weber is commemorated in the scientific names of three species of reptiles: "Anomochilus weberi", "Hydrosaurus weberi", and "Pachydactylus weberi". Two species of mammal are also named after him: "Prosciurillus weberi" and "Myotis weberi".
Abyssal plain named in his honor.
