James studied geographic variation in the size and shape of birds, leading to transplant experiments with red-winged blackbirds and to tests of the theoretical assumptions underlying selection models. She is a member of the American Academy of Arts and Sciences. James, originally from Philadelphia, Pennsylvania, was immersed in the stream of biology at an early age being involved in the Academy of Natural Sciences Expeditions for Everyone. [1]

In 1984 James was the first woman to become president of the American Ornithologists Union serving for two years until 1986. [2] She was awarded the Eminent Ecologist Award in January 1997; in the same year she also received the Outstanding Leadership Award from the American Institute of Biological Sciences. [1] She was awarded the 1999 Margaret Morse Nice Medal by the Wilson Ornithological Society. [3] She has served on The Nature Conservancy Board of Governors and the Board of Directors for the World Wildlife Fund. [4]

Academic career

James completed her A.B. (Bachelor of Arts) in zoology at Mount Holyoke College and went on to do her M.S. (Master of Science) at Louisiana State University. [1] She then finished her Ph.D. in Zoology from the University of Arkansas in 1970 at the age of 40 after raising a family of three daughters with her then husband ornithologist Douglas A. James. [1] Her dissertation involved observing patterns of intraspecific size variation in 12 species of birds found in areas of the United States. [1] James looked specifically at Bergmann’s rule hypothesizing that temperature may not be the most important factor determining body size patterns across gradients. [1]

In 1996 Frances James and her colleague at the University of Florida, statistician Charles McCulloch published an article titled: New Approaches to Population Trends in Land Birds. [1] They proposed novel approaches to analyzing the data from the Breeding Bird Survey, data showed no general decline but significant declines in species from certain regions. [4]

In 2009, with John Pourtless, she published an Ornithological Monograph entitled "Cladistics and the Origin of Birds: A Review and Two New Analyses". In this monograph they argue that both the “early-archosaur” and “crocodylomorph” hypotheses are at least as well supported as the BMT (birds are maniraptoran theropod dinosaurs) hypothesis. Also, the Kishino-Hasegawa tests [5] they performed revealed no statistical difference between the hypothesis that birds were a clade nested within the Maniraptora and the hypothesis that core clades of Maniraptora (oviraptorosaurs, troodontids, and dromaeosaurs) were actually flying and flightless radiations within the clade bracketed by Archaeopteryx and modern birds (Aves). James and Pourtless concluded that because Aves might not belong within it, Theropoda as presently constituted might not be monophyletic. They further cautioned that a verificationist approach in the BMT literature may be producing misleading studies on the origin of birds. [6]

Cladistics is an approach to biological classification in which organisms are categorized in groups ("clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived characteristics (synapomorphies) that are not present in more distant groups and ancestors. However, from an empirical perspective, common ancestors are inferences based on a cladistic hypothesis of relationships of taxa whose character states can be observed. Theoretically, a last common ancestor and all its descendants constitute a (minimal) clade. Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms worms or fishes were used within a strict cladistic framework, these terms would include humans. Many of these terms are normally used paraphyletically, outside of cladistics, e.g. as a 'grade', which are fruitless to precisely delineate, especially when including extinct species. Radiation results in the generation of new subclades by bifurcation, but in practice sexual hybridization may blur very closely related groupings.

The American Ornithological Society (AOS) is an ornithological organization based in the United States. The society was formed in October 2016 by the merger of the American Ornithologists' Union (AOU) and the Cooper Ornithological Society. Its members are primarily professional ornithologists, although membership is open to anyone with an interest in birds. The society publishes the two scholarly journals, The Auk and The Condor as well as the AOS Checklist of North American Birds.

Storrs Lovejoy Olson was an American biologist and ornithologist who spent his career at the Smithsonian Institution, retiring in 2008. One of the world's foremost avian paleontologists, he was best known for his studies of fossil and subfossil birds on islands such as Ascension, St. Helena and Hawaii. His early higher education took place at Florida State University in 1966, where he obtained a B.A. in biology, and the University of Florida, where he received an M.S. in biology. Olson's doctoral studies took place at Johns Hopkins University, in what was then the School of Hygiene and Public Health. He was married to fellow paleornithologist Helen F. James.

Apsaravis is a Mesozoic bird genus from the Late Cretaceous. The single known species, Apsaravis ukhaana, lived about 78 million years ago, in the Campanian age of the Cretaceous period. Its fossilized remains were found in the Camel's Humps sublocality of the Djadokhta Formation, at Ukhaa Tolgod in the Gobi Desert of Mongolia. They were collected in the 1998 field season by the Mongolian Academy of Sciences/American Museum of Natural History Paleontological Expeditions. It was described by Norell and Clarke (2001).

Joseph Hurd Connell FAA was an American ecologist. He earned his MA degree in zoology at the University of California, Berkeley and his PhD at Glasgow University. Connell's first research paper examined the effects of interspecific competition and predation on populations of a barnacle species on the rocky shores of Scotland.</ref> According to Connell, this classic paper is often cited because it addressed ecological topics that previously had been given minor roles. Together, with a subsequent barnacle study on the influence of competition and desiccation, these two influential papers have laid the foundation for future research and the findings continue to have relevance to current ecology. His early work earned him a Guggenheim fellowship in 1962 and the George Mercer Award in 1963.
