The Theodore Roosevelt Memorial Fund

Theodore Roosevelt Statue

Since establishment of the Theodore Roosevelt Memorial Fund in 1961, the American Museum of Natural History (AMNH) has provided funding for young scientists through Research GrantsPostdoctoral Fellowships and Graduate Student Fellowships, thanks to generous initial gifts and the ongoing support of the Theodore Roosevelt Association and individual donors. The Theodore Roosevelt Memorial Fund’s mission is to support research in any phase of wildlife conservation or related fields of North American natural history that are included in the activities of the AMNH. Research can be on the terrestrial or freshwater aquatic fauna of North America, living or fossil, covering all territory north of the Isthmus of Panama including the Caribbean. A standing committee of the AMNH’s Richard Gilder Graduate School (RGGS), including distinguished Curators and representatives of the Theodore Roosevelt Association, recommend the awardees each year from among applicants reviewed and nominated by AMNH academic staff.

The Theodore Roosevelt Memorial Research Grants

Theodore Roosevelt Memorial Research Grants are meant to provide seed money for research projects, to foster professional development and encourage studies on the North American fauna to which Theodore Roosevelt, 26th President of the United States, devoted so much of his time and energy. Grants typically range from $1000 to $3500 each, and in 2016, 29 grants were awarded. Since the inception of the program, over 2100 Theodore Roosevelt Research Grants, totaling close to $2 million, have been awarded to doctoral students, postdoctoral researchers and other early career scientists from around the world.

Examples of recent research projects supported by Theodore Roosevelt Memorial Fund grants include: 
   -Movement and Habitat Selection of Prairie Rattlesnakes in Central Idaho 
   -Cranial Variation in Triceratops from the Hell Creek Formation, Montana
   -Colonization and Gene Flow of Coastal Tailed Frogs (Ascaphus truei) at Mount St. Helens
   -Ecdysteroid Natural History and Ecological Function in two North American Gryllus Species
   -Systematics and Conservation of the Southern Cavefish Species Complex 
   -Leeches of Chiapas, Mexico
   -Multiproxy Characterization of the Late Devonian Hangenberg Bioevent in Ohio

USA Today (July 24, 2018) – Largest dinosaur foot to date discovered in Wyoming, say paleontologists

Paleontologists with the American Museum of Natural History say they've discovered the largest dinosaur foot to date. A study published Tuesday in the journal Peerj identified the foot found in Wyoming as belonging to a brachiosaur, one of the largest land animals on Earth. "There are tracks and other incomplete skeletons from Australia and Argentina that seem to be from even bigger animals, but those gigantic skeletons were found without the feet," said Emanuel Tschopp, a postdoctoral fellow in the American Museum of Natural History's Division of Paleontology, and co-author of the study, in a statement.

AMNH POSTDOCTORAL AND GRADUATE FELLOWS SUPPORTED BY THE THEODORE ROOSEVELT MEMORIAL FUND

Theodore Roosevelt Memorial Fellowships also may be awarded to AMNH-affiliated postdoctoral fellows and graduate fellows supported by the Theodore Roosevelt Memorial Committee upon recommendation of the AMNH Science divisions, RGGS faculty and RGGS Academic Affairs and Fellowships Committee. Details on these programs are available here for Graduate Fellowships and here for Postdoctoral Fellowships.

Research Interests: Sauropod evolution, systematics, and diversity; Morrison Formation megaherbivore distribution and demographics; Phenotypic specimen-level phylogeny

Research Focus – My postdoctoral research is focused on understanding potential geographic segregation among megaherbivores of the Upper Jurassic Morrison Formation of the western United States. The Morrison Formation was deposited 150 Million years ago, and produced one of the the best known and most diverse vertebrate faunas worldwide. The diversity and abundance of the gigantic sauropod dinosaurs is particularly interesting and hard to explain. My work at the AMNH focuses on the systematics of sauropods from the northern part of the Morrison Formation, which has not been studied in detail. Comparison of these new data will show if geographical differences in species composition may explain part of the high diversity of megaherbivores in this extinct ecosystem. Ultimately this work will help to understand how an ecosystem is able to sustain and maintain a high diversity of gigantic herbivores over a long time (millions of years).

In addition to the work on sauropods, I will continue my methodological work on specimen-level phylogeny using morphology, and species delimitation in vertebrates. This work seeks to improve how paleontologists identify new species and quantify and track biodiversity changes in Deep Time. For example, collaborators and I are testing the methodology in a variety of living squamate reptile clades in order to understand which combination of approaches works best in which taxon.

Biography - Emanuel Tschopp received his M.Sc. in Paleontology from University of Zurich (Switzerland) in 2008 and Ph.D. from the University NOVA of Lisbon (Portugal) in Geology in 2014, under the supervision of Prof. Octavio Mateus. His dissertation focused on specimen-level phylogeny and systematics of diplodocid sauropod dinosaurs. Later, he did a Volkswagen Foundation Postdoc at University NOVA on specimen-level phylogeny of the sauropod Camarasaurus, and a Marie Curie Postdoc at University of Turin (Italy) on the methodology of specimen-level phylogeny using the lacertid lizard genus Lacerta.

Research Interests: Snake evolution, systematics, and taxonomy; comparative population genomics and phylogeography; speciation

Research Focus – My postdoctoral research is focused on understanding variation in rattlesnake venom. Viperids, the family of snakes that includes rattlesnakes (Crotalus and Sistrurus), have venoms that are largely characterized as hemotoxic or hemorrhagic. However, a number of rattlesnake species and populations posses a potent neurotoxin. Despite these species being widespread within North America and being of medical importance, how these venoms have evolved is still unresolved. Recent studies have suggested that neurotoxic venoms are shared between rattlesnake species or populations because of past hybridization events (e.g. Zancolli et al. 2016 and Rokyta et al. 2015). However, other studies have concluded that the ancestor to all rattlesnakes possessed the genes responsible for these neurotoxins, and therefore species that lack this component in their venom have lost these genes at some point during their evolutionary history. My work will focus on addressing these competing hypotheses. In order to do so I will be generating RNA-seq data from venom glands and designing a set of DNA-probes to sequence venom genes across Crotalus. Ultimately this work will address how many times neurotoxin genes have evolved and whether hybridization plays a large role in the distribution of this trait across the rattlesnake phylogeny, which may contribute to our understanding of venom evolution in other snake groups as well as trait evolution in general.

In addition to the rattlesnake work, I will continue to work on population genomics and species delimitation in a number of North American snake taxa. This work seeks to address the mechanisms of speciation, while quantifying biodiversity within the US and Mexico. For example, collaborators and I are generating a genomic data set for the genus Pantherophis (rat snakes and corn snakes) to test species boundaries and to understand color pattern evolution in snakes.

Biography - Edward A. Myers received his B.Sc. in Zoology from Washington State University in 2009 and Ph.D. from the City University of New York in Biology in 2016, under the supervision of Dr. Frank Burbrink. His dissertation focused on comparative population genomics and ecological speciation of codistributed snakes across the desert southwest of North America.
