The African clawed frog, also known as simply xenopus, African clawed toad, African claw-toed frog or the platanna) is a species of African aquatic frog of the family Pipidae. Its name is derived from the short black claws on its feet. The word Xenopus means 'strange foot' and laevis means 'smooth'.
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.
The moor frog is a slim, reddish-brown, semiaquatic amphibian native to Europe and Asia. Moor frogs are known for their ability to freeze solid and survive thawing. The frog makes use of various cryoprotectants i.e. antifreeze that decrease its internal freezing temperature. The species is distributed over a large range, covering a significant portion of Eurasia. Male moor frogs are known to turn blue temporarily during the height of mating season. This coloration is assumed to signal a mate's fitness. Moor frogs typically mate through multimale amplexus a form of polyandry.

David Mark Hillis is an American evolutionary biologist, and the Alfred W. Roark Centennial Professor of Biology at the University of Texas at Austin.

Naomi E. Pierce is an American entomologist and evolutionary biologist who studies plant-herbivore coevolution and is a world authority on butterflies.
Theodore Garland Jr. is a biologist specializing in evolutionary physiology at the University of California, Riverside.
Susan Elizabeth Evans is a British palaeontologist and herpetologist. She is the author or co-author of over 100 peer-reviewed papers and book chapters.
The Sixth Extinction: An Unnatural History is a 2014 nonfiction book written by Elizabeth Kolbert and published by Henry Holt and Company. The book argues that the Earth is in the midst of a modern, man-made, sixth extinction. In the book, Kolbert chronicles previous mass extinction events, and compares them to the accelerated, widespread extinctions during our present time. She also describes specific species extinguished by humans, as well as the ecologies surrounding prehistoric and near-present extinction events. The author received the Pulitzer Prize for General Nonfiction for the book in 2015.
Catherine H. Graham is an American team leader and senior scientist working on the Biodiversity & Conservation Biology, and the Spatial Evolutionary Ecology research units at the Swiss Federal Institute for Forest, Snow and Landscape Research WSL. From 2003 to 2017 she was an Assistant, Associate, or Full Professor of Ecology and Evolution at the Stony Brook University, and since her appointment at the WSL in 2017 she has maintained adjunct status there. She received both her M.S. degree (1995) and her Ph.D. (2000) from the University of Missouri at St. Louis, and did post-doctoral training at the Jet Propulsion Laboratory and the University of California, Berkeley. She studies biogeography, conservation biology, and ecology. Catherine H. Graham is most noted for her analysis of statistical models to describe species' distributions. This work with Jane Elith is useful in determining changes in biodiversity resulting from human activities. Her paper on niche conservatism with John J. Wiens is also highly cited. They focused on how species' retention of ancestral traits may limit geographic range expansion. In many of her papers, she has sought to unite ecology and evolutionary biology to derive a better understanding of the processes driving species diversity patterns. In particular, she and Paul Fine laid out a framework for interpreting community assembly processes from a phylogenetic approach to quantifying beta diversity.
Rosemary Gillespie is an evolutionary biologist and professor of Environmental Science, Policy & Management, Division of Insect Biology at the University of California, Berkeley. She was the President of the American Genetics Association in 2018 and was previously President of the International Biogeography Society 2013–2015. From 2011 to 2013 she had served at the president of the American Arachnological Society. As of 2020 she is the faculty director of the Essig Museum of Entomology and a Professor and Schlinger Chair in systematic entomology at the University of California, Berkeley. Gillespie is known for her work on the evolution of communities on hotspot archipelagoes.
Marvalee Hendricks Wake is an American zoologist and professor at the University of California, Berkeley, known for her research in the biology of caecilians and vertebrate development and evolution. A 1988 Guggenheim Fellow, she has served as president of the American Institute of Biological Sciences, the American Society of Ichthyologists and Herpetologists, Society for Integrative and Comparative Biology, International Union of Biological Sciences, and the International Society of Vertebrate Morphology. She is a fellow of the American Association for the Advancement of Science and the California Academy of Sciences, and is a member of the American Academy of Arts and Sciences.
Countergradient variation is a type of phenotypic plasticity that occurs when the phenotypic variation determined by a biological population's genetic components opposes the phenotypic variation caused by an environmental gradient. This can cause different populations of the same organism to display similar phenotypes regardless of their underlying genetics and differences in their environments.
Tanya M. Smith is a human evolutionary biologist, and Professor at the Australian Research Centre for Human Evolution, Griffith University.
Rebecca Marie Calisi is an American neuroendocrinologist, wildlife biologist, and National Geographic Explorer. She is an Associate professor of Neurobiology, Physiology, and Behavior in the College of Biological Sciences at the University of California, Davis. She leads a research team that studies how the brain controls sexual behavior, reproduction, and parental care, and how this changes under stress. As the Director for Science Communications at UC Davis, she studies science communication and advocates for inclusivity, equity, and diversity in STEM.
Barbara Ambrose is a botanist working in the field of Plant Evolutionary Developmental Biology (Evo-Devo). As the Director of Laboratory Research at the New York Botanical Garden, Ambrose is a prolific scholar and leader and mentor in her field who is interested in patterns in plant diversity on macro and micro scales.
Stephanie M. Carlson is the A.S. Leopold Chair in Wildlife Biology at the University of California Berkeley. Her research considers fish ecology, freshwater ecology, and evolutionary ecology.
Joy Michele Bergelson is an American evolutionary biologist. She is currently the Dorothy Schiff Professor of Genomics at New York University. Bergelson was previously and James D. Watson Distinguished Service Professor of Ecology and Evolution at the University of Chicago, where she chaired the department for ecology and evolution. Her research focuses on the evolution and ecology of plants.
Britt Koskella is an associate professor at the University of California, Berkeley, USA. She studies evolutionary biology, specialising in host-pathogen relationships.
Jessica Hua is an associate professor in the Department of Biological Sciences at Binghamton University, NY. In addition Hua is the Director for the Center for Integrated Watershed Studies at Binghamton University which focuses on understanding watersheds and the human influences on them through research. She is a herpetologist and oversees her own lab, The Hua Lab, where they focus on ecological interactions, evolutionary processes and ecological-evolutionary feedbacks. Hua's background has led to her appreciation of education with coming from a refugee family who "epitomizes the concept of the American Dream". Her research aims to help others gain opportunities while also establishing a lab that is inclusive and diverse. Hua also enjoys a variety of sports and plays disc golf professionally since 2016.
