Maren Birgit Gaulke (born 4 April 1955) is a German herpetologist whose research focus has been the biology of monitor lizards, snakes and turtles.
In the mid-1980s she began her field work in Southeast Asia and the Philippines, where her biological studies collected new insights into the ecology, ethology and trophic dependencies of tropical animals.
She contributed chapters to the books Anoxia: Evidence for Eukaryote Survival and Paleontological Strategies (2012) by Alexander Volker Altenbach, Joan M. Bernhard and Joseph Seckbach and Varanoid Lizards of the World (2004) by Eric Pianka and R. Dennis King.
In addition, her scientific contributions have appeared in several international journals, including Hamadryad, Zootaxa,[5] Elaphe, Herpetozoa, Asiatic Herpetological Research, Salamandra and Copeia.
In 2008, Gernot Vogel and Johan van Rooijen named the bronze snake species Dendrelaphis marenae in honor of Maren Gaulke.
