Life

Losos studied biology at Harvard University, from which he received a Bachelor's degree in 1984. Later on, in 1989, he received a PhD in Zoology from the University of California, Berkeley (Ecomorphological Adaptation in the Genus Anolis). Starting in 1987, he worked as a Teaching assistant in Berkeley. After receiving his PhD, he moved to the University of California, Davis in 1990 to become one of the inaugural postdoctoral fellows at the Center for Population Biology. Losos then, from 1992 on, was assistant professor at the Washington University in St. Louis, and then was promoted to the rank of associate professor in 1997 and professor in 2001. [1]

His work focuses on a wide range of topics, but he is best known for his studies of convergent evolution and adaptive radiation, and for experimental studies of evolution in nature. [2] Most of his empirical work has involved the evolutionary radiation of lizards in the genus Anolis which occur in Central and South America and on islands in the Caribbean.

From 2000 to 2003 and 2004–2005, Losos was director of Tyson Research Center at Washington University in St. Louis. In 2006, Losos left Washington University to become the Monique and Philip Lehner Professor for the Study of Latin America at Harvard University and Professor in the Department of Organismic and Evolutionary Biology, as well as Curator in Herpetology of the Museum of Comparative Zoology. Losos then returned to Washington University in 2018 to become the William H. Danforth Distinguished University Professor in the Department of Biology, as well as the founding director of the Living Earth Collaborative, a biodiversity partnership between Washington University, the Missouri Botanical Garden and the Saint Louis Zoo. [3]

Honors and awards

Losos has received a number of awards, including the Dobzhansky Prize in 1991, the David Starr Jordan Prize in 1998, the Edward O. Wilson Naturalist Award in 2009, the Daniel Giraud Elliot Medal in 2012 and the Sewall Wright Award in 2019. [4]

Losos is a Fellow of the American Association for the Advancement of Science (2005), as well as the American Academy of Arts and Sciences (2012) and the National Academy of Sciences (2018). In 2016, he received the Distinguished Herpetologist award of The Herpetologists' League. [1]

<span class="mw-page-title-main">Adaptive radiation</span> A process in which organisms diversify rapidly from an ancestral species

In evolutionary biology, adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available, alters biotic interactions or opens new environmental niches. Starting with a single ancestor, this process results in the speciation and phenotypic adaptation of an array of species exhibiting different morphological and physiological traits. The prototypical example of adaptive radiation is finch speciation on the Galapagos, but examples are known from around the world.

<span class="mw-page-title-main">Dactyloidae</span> Family of reptiles

Dactyloidae are a family of lizards commonly known as anoles and native to warmer parts of the Americas, ranging from southeastern United States to Paraguay. Instead of treating it as a family, some authorities prefer to treat it as a subfamily, Dactyloinae, of the family Iguanidae. In the past they were included in the family Polychrotidae together with Polychrus, but the latter genus is not closely related to the true anoles.

<i>Anolis</i> Genus of lizards

Anolis is a genus of anoles, iguanian lizards in the family Dactyloidae, native to the Americas. With more than 425 species, it represents the world's most species-rich amniote tetrapod genus, although many of these have been proposed to be moved to other genera, in which case only about 45 Anolis species remain. Previously, it was classified under the family Polychrotidae that contained all the anoles, as well as Polychrus, but recent studies place it in the Dactyloidae.

<span class="mw-page-title-main">Sewall Wright</span> American geneticist (1889–1988)

Sewall Green Wright FRS(For) Honorary FRSE was an American geneticist known for his influential work on evolutionary theory and also for his work on path analysis. He was a founder of population genetics alongside Ronald Fisher and J. B. S. Haldane, which was a major step in the development of the modern synthesis combining genetics with evolution. He discovered the inbreeding coefficient and methods of computing it in pedigree animals. He extended this work to populations, computing the amount of inbreeding between members of populations as a result of random genetic drift, and along with Fisher he pioneered methods for computing the distribution of gene frequencies among populations as a result of the interaction of natural selection, mutation, migration and genetic drift. Wright also made major contributions to mammalian and biochemical genetics.

Joan Roughgarden is an American ecologist and evolutionary biologist. She has engaged in theory and observation of coevolution and competition in Anolis lizards of the Caribbean, and recruitment limitation in the rocky intertidal zones of California and Oregon. She has more recently become known for her rejection of sexual selection, her theistic evolutionism, and her work on holobiont evolution.

Hobart Muir Smith, born Frederick William Stouffer, was an American herpetologist. He is credited with describing more than 100 new species of American reptiles and amphibians. In addition, he has been honored by having at least six species named after him, including the southwestern blackhead snake, Smith's earth snake, Smith's arboreal alligator lizard, Hobart's anadia, Hobart Smith's anole, and Smith's rose-bellied lizard. At 100 years of age, Smith continued to be an active and productive herpetologist. Although he published on a wide range of herpetological subjects, his main focus throughout his career was on the amphibians and reptiles of Mexico, including taxonomy, bibliographies, and history. Having published more than 1,600 manuscripts, he surpassed all contemporaries and remains the most published herpetologist of all time.

David Burton Wake was an American herpetologist. He was professor of integrative biology and Director and curator of herpetology of the Museum of Vertebrate Zoology at the University of California, Berkeley. Wake is known for his work on the biology and evolution of salamanders as well as general issues of vertebrate evolutionary biology. He has served as president of the Society for the Study of Evolution, the American Society of Naturalists, and American Society of Zoologists. He was a member of the American Association for the Advancement of Science, the Linnean Society of London, the American Academy of Arts and Sciences, the American Philosophical Society, and in 1998 was elected into the National Academy of Sciences. He was awarded the 2006 Leidy Award from the Academy of Natural Sciences of Philadelphia.

The American Society of Naturalists was founded in 1883 and is one of the oldest professional societies dedicated to the biological sciences in North America. The purpose of the Society is "to advance and diffuse knowledge of organic evolution and other broad biological principles so as to enhance the conceptual unification of the biological sciences."

<i>Anolis</i> ecomorphs Grouping of species of lizard

The ecomorph concept is a term first coined by Ernest Edward Williams in 1972 which he defined as a “species with the same structural habitat/niche, similar in morphology and behavior, but not necessarily close phyletically.” Williams first applied this definition to the Greater Antillean anoles upon observing their evolutionary radiation, although it has since been used widely elsewhere.
