Question: What Small native cat to North and South America did Carl B. Koford make studies on in the 50's and 70's?

full_context: Document 1: Jaguar Conservation Fund: The Jaguar Conservation Fund (JCF), known in Portuguese as (IOP), was founded in June 2002 by a group of researchers with a strong background of work dedicated to the species. Its mission is “To promote the conservation of the jaguar, its natural prey and habitat throughout the species' geographical range, as well as its peaceful coexistence with man, through research and conservation strategies". The largest part (48%) of the jaguar’s geographical distribution, which extends from northern Argentina to the southwestern United States, lies within Brazil. However, although nationally considered endangered, until the foundation of the JCF few programs focusing on conservation of the species existed. Today, JCF is the only Brazilian NGO (non-governmental organization) devoted exclusively to promoting the conservation of the jaguar. It is currently implementing scientific research in four Brazilian biomes (Amazon, Cerrado, Caatinga and Pantanal) and supports partner organizations in the Atlantic Forest. Research topics include long-term population monitoring programs for jaguars and their main prey species, and management programs to solve the conflict between the predator and livestock ranchers. Additionally, JCF's projects of cultural, educational and social character contribute to conservation of the jaguar, biodiversity, and to reduction of the effects of global warming. In order to facilitate contact between non-Brazilian supporters/sponsors and JCF activities in Brazil, the Jaguar Conservation Fund –US was founded in 2004 as a 501©3 non-profit organization.
Document 2: Jaguarundi: The jaguarundi ("Puma yagouaroundi") ( ) or eyra cat is a small wild cat native to southern North America and South America. It has been listed as Least Concern on the IUCN Red List since 2002. Its presence in Uruguay is uncertain. The megareserves of the Amazon Basin are probably the only conservation units that can sustain long-term viable populations.
Document 3: Michael Bigg: Dr. Michael A. Bigg (1939–1990) was a Canadian marine biologist who is recognized as the founder of modern research on killer whales. With his colleagues, he developed new techniques for studying killer whales and conducted the first population census of the animals. Bigg's work in wildlife photo-identification enabled the longitudinal study of individual killer whales, their travel patterns, and their social relationships in the wild, and revolutionized the study of cetaceans.
Document 4: K. Christopher Beard: K. Christopher Beard is an American paleontologist, a world-renowned expert on the primate fossil record and a 2000 MacArthur Fellowship “Genius” Award Winner. Beard's research is reshaping critical debates about the evolutionary origins of mammals, including primates, routinely questioning current thinking about their geographical origins. Dr. Beard is the former Curator of the Carnegie Museum of Natural History, and Mary R. Dawson Chair of Vertebrate Paleontology, at University of Pittsburgh. He is currently Distinguished Foundation Professor, Senior Curator at the University of Kansas. He was co-author with Dan Gebo about an extinct primate from China. Dr. Beard also authored the book The Hunt for the Dawn Monkey: Unearthing the Origins of Monkeys, Apes and Humans. Beard was also part of the research teams that discovered Teilhardina, the earliest primate ever found in North America, and Eosimias, one of the earliest higher primates yet discovered. He worked with NASA to scan a "Tyrannosaurus rex" skull. Beard received his PhD from the Functional Anatomy and Evolution Program at Johns Hopkins University School of Medicine in 1989.
Document 5: David Boynton: David Boynton (1945–2007) was a leading expert on the natural history of the Hawaiian island of Kauai, especially on the Koke'e Forest and the Alakai Swamp and its wildlife. He was called "a voice for the Hawaiian wilderness," a "Guardian of the Koke'e Forest," and as an educator, "the window through which thousands of Hawai'i students learned about Hawaiian birds, plants, marine creatures, climate and much more." Boynton photographed a bird now believed extinct, the ʻ Ōʻ ōʻ āʻ ā ("Moho braccatus"). He recorded the mating call of the single male, whose mate presumably did not survive Hurricane Iwa at the end of 1982. The bird, probably the last of its species, was tending an empty nest.
Document 6: Berkeley School of Latin Americanist Geography: The Berkeley School of Latin Americanist Geography was founded by the American geographer Carl O. Sauer. Sauer was a professor of geography at the University of California at Berkeley from 1923 until becoming professor emeritus in 1957 and was instrumental in the early development of the geography graduate program at Berkeley and the discipline of geography in the United States. Each generation of this research school has pursued new theoretical and methodological approaches, but their study of the peoples and places of Latin America and the Caribbean has remained the common denominator since the early 20th century. Carl O. Sauer himself did not develop a particular interest in Latin America before 1925, when Oskar Schmieder, a German geographer, disciple of Alfred Hettner, and expert in Latin American regional geography, arrived at Berkeley, coming from Córdoba, Argentina, to work as an Associate Professor. Obviously, his interest awoke during Schmieder's presence between 1925 and 1930. After Schmieder's departure in 1930, Carl O. Sauer began to offer seminars on the regional geography of Latin America.
Document 7: Galictis: A grison, also known as a South American wolverine, is any mustelid in the genus Galictis. Native to Central and South America, the genus contains two extant species: the greater grison ("Galictis vittata"), which is found widely in South America, through Central America to southern Mexico; and the lesser grison ("Galictis cuja"), which is restricted to the southern half of South America. In Spanish it is referred to as a "huroncito" (literally "little ferret") or "grisón" and in Portuguese as a "furão".
Document 8: Pantanal cat: The Pantanal cat ("Leopardus colocola braccatus") is a Pampas cat subspecies, a small wild cat native to South America. It is named after the Pantanal wetlands in central South America, where it inhabits mainly grassland, shrubland, savannas and deciduous forests.
Document 9: Carl F. Brand: Carl Fremont Brand (October 8, 1892 – March 27, 1981) was an American historian. He was a professor of history at Stanford University for thirty-four years, and was one of the leading American authorities on the history of the British Labour Party. His books, "British Labour's Rise to Power" (1941) and "The British Labour Party" (1964), are regarded as definitive works in this field. He built the Hoover Institution's collection of Labour Party documents, long recognized as the finest collection outside of the United Kingdom.
Document 10: Cougar: The cougar ("Puma concolor"), also commonly known as the mountain lion, puma, panther, or catamount, is a large felid of the subfamily Felinae native to the Americas. Its range, from the Canadian Yukon to the southern Andes of South America, is the greatest of any large wild terrestrial mammal in the Western Hemisphere. An adaptable, generalist species, the cougar is found in most American habitat types. It is the second-heaviest cat in the New World, after the jaguar. Secretive and largely solitary by nature, the cougar is properly considered both nocturnal and crepuscular, although there are daytime sightings. The cougar is more closely related to smaller felines, including the domestic cat (subfamily Felinae), than to any species of subfamily Pantherinae, of which only the jaguar is native to the Americas.
Document 11: Carl B. Koford: Carl Buckingham Koford (September 3, 1915 in Oakland, California – December 3, 1979 in Berkeley, California) was an American biologist who is known for his research work on the behavior of the California condor. He attended the Piedmont High School and studied at the University of Washington. Koford began his field work about the California condor in March 1939. More than 400 days until June 1941 he spend with the condors. During World War II he interrupted his studies to serve in the U.S. Navy. In 1946 his observations on the condors continued. In 1953 he published the report "The California Condor" where he gave a first estimation of the world population of about 60 individuals. In the 1950s and again in the 1970s he went to South America where he made studies on species like the Vicuña, the Jaguar, the Ocelot or the Jaguarundi. After rumours about the survival of some individuals of the thought to be extinct Mexican grizzly bear Koford went to Mexico in 1969 but he failed to rediscover this bear.
Document 12: Robert Ricklefs: Born in 1943, he graduated with an Bachelor of Science from Stanford University in 1963 and a Ph.D. from the University of Pennsylvania in 1967. He completed a year as a postdoctoral fellow at the Smithsonian Tropical Research Institute before taking up a faculty position at the University of Pennsylvania. He was the 1982 recipient of the American Ornithologists' Union's William Brewster Memorial Award, the union's most prestigious award given annually for an exceptional body of work on birds of the Western Hemisphere. In 2003, he received the Pacific Seabird Group's Lifetime Achievement Award for his work on growth and development in seabirds. He was awarded the 2003 Margaret Morse Nice Medal by the Wilson Ornithological Society. He was the 2006 recipient of the Cooper Ornithological Society’s Loye and Alden Miller Research Award, which is given in recognition of lifetime achievement in ornithological research.
Document 13: Iberian lynx: The Iberian lynx ("Lynx pardinus") is a wild cat species native to the Iberian Peninsula in southwestern Europe that is listed as Endangered on the IUCN Red List.
Document 14: Cry of the Kalahari: Cry of the Kalahari (1984) is an autobiographical book detailing two young American zoologists, Mark and Delia Owens, and their experience studying wildlife in the Kalahari desert in Botswana in the mid-1970s. There they lived and worked for seven years in an unexplored area named Deception Valley in the Central Kalahari Game Reserve. With no roads and no people and the nearest civilization eight hours away they had only each other and the animals they studied as company, most of which had never seen humans before. Their research focused mainly on lions, brown hyenas, jackals and other African carnivores. "Cry of the Kalahari" is the personal story of the Owens' encounters with these and a myriad of other animals and depicts their own struggle to live and work in such an inhospitable and unforgiving environment.
Document 15: Northern South American cougar: The Northern South American cougar ("Puma concolor concolor") is not only a subspecies of the cougar ("Puma concolor"), but also its nominate subspecies. It is native to northern South America, living from Colombia and Venezuela to Peru and northern Brazil.
