Dr. Nils Chr. Stenseth, of the University of Oslo (UiO), Norway, is one of the most influential and productive scientists of our times.  He is thoroughly Norsk, obtaining both his Cand. Mag. (1972) and D. Philos. (1978) at UiO, where he has remained on the faculty throughout his career.  His scientific productivity is prodigious, with over 800 publications, including at least a half dozen books and 17 pubs in Science, 21 in Nature, and 36 in PNAS.  Dr. Stenseth has mentored more than 50 PhD students and more than 70 postdocs.  He has been on the graduate committees of students from all over the world, and has dedicated considerable effort to Africa, where he is adjunct professor at the University of Addis Ababa, Ethiopia.

Dr. Stenseth combines theoretical and empirical approaches in his research, focusing on an ever-changing variety of ecological and evolutionary subjects.  Some of his important early work concerned population dynamics of small mammals, notably population cycles.  He tackled complex issues like the effects of density dependent and density independent factors on these dynamics, and introduced needed rigor into a contentious field.  He tested hypotheses about the relative roles of intrinsic and extrinsic factors on population dynamics, using mathematics and modelling to test ideas that had previously only been verbal.  His interests are question-driven more than taxon-driven (although he retains a fondness for lemmings to this day), and his research ranges over a variety of taxa and regions.  In fact, he has published studies on mammals on all continents except Antarctica.  He also specializes on analyzing long-term empirical data sets.  He has a unique aptitude for identifying ecological and evolutionary problems that could be addressed in these time series with proper statistical analysis, and tackles research questions by using empirical data informed by perspectives from theory.  Beside population biology and evolution, Nils has worked on the effects of climate change on biodiversity (mostly mammals and fish), the relationship of small mammal populations with vector-borne diseases (notably plague), and climatic and harvesting effects on marine populations.

Dr. Stenseth was the founding chair of the Center for Ecological and Evolutionary Synthesis at the University of Oslo, bringing together top-level scientists working on complex issues and encouraging collaboration.  He also believes science needs to be understood by the lay public, and engages in many outreach and educational activities such as writing newspaper articles, essays and editorials in journals, giving open, public lectures, and appearing on podcasts.  Dr. Stenseth has received many awards and recognitions from scientific organizations around the world, and is a member of the Royal Societies or Academies of Science of 10 countries, including the U. S. National Academy of Sciences. He is a past-president of the International Federation of Mammalogists and the International Union of Biological Sciences.  The American Society of Mammalogists is proud to now also claim him as an Honorary Member.

Dr. Afework Bekele Simegn has been called “one of the best mammal biologists that the African continent has produced.”  He received a B.S. degree from Addis Ababa University in his native Ethiopia (1972), then went on to earn a M.S. degree at Manchester University, England (1980).  Pursuit of his Ph.D. was interrupted by political differences between the U.K. and Ethiopia, but he persisted with his study of mammals and returned to the University of Manchester to complete his doctorate (1994) after the countries reconciled. Dr. Bekele has since held various teaching and research positions at Addis Ababa University.  Neither violent civil wars, dictatorial purges, nor intense famines have deterred him from maintaining a highly productive and influential scientific career.

Image

Dr. Bekele has over 300 publications mostly on Ethiopian mammals, but also on birds.  They include a mix of natural history, systematics, ecology, and conservation.  Many are in highly respected, peer-reviewed international journals, but many also are in African journals where they have the greatest impact on their intended readers.  The nominee also was the author of Mammals of Ethiopia and Eritrea (co-authored by his PhD mentor Dr. Derek Yalden), a vital resource for mammalogists working in East Africa. 

Education has been a strong focus of Dr. Bekele, who has received both departmental and university-wide awards for research and teaching. He has mentored over 100 MS students and 60 PhD students in Ethiopia, as well as many graduate students from other countries in Africa, and 6 Ph.D. students at the University of Oslo, Norway, where he has an adjunct appointment.  Many of these students have gone on to academic careers at African institutions, and many have pursued professional careers in conservation of African wildlife.  Recognizing that students become more involved when they personally relate to the subject matter, Dr. Bekele co-authored a university-level biology textbook using African examples to illustrate biological concepts.

To house and preserve the specimens Dr. Bekele, his students, and others collected in East Africa, he initiated and developed a zoological museum of natural history at Addis Ababa University and served as its director for 12 years.  Dr. Bekele is sometimes called “the father of Ethiopian Biology”, and serves as the specialist for Ethiopian mammals for CITES and on the IUCN African Antelopes and Rodents committees.  The nominee is a member of the Ethiopian Academy of Sciences, and was president of the Biological Society of Ethiopia from 1999 to 2002.

Dr. Bekele has served as a contact point, advisor, and facilitator for many international researchers seeking to conduct mammalian research in East Africa.  Ethiopia has phenomenal biodiversity, particularly in its highlands, including many endemic species. During just the past decade, Dr. Bekele has co-authored papers (often with students) on the ecology and systematics of a variety of primates, ungulates (including warthogs), small mammals, and the endemic Ethiopian wolf, and conservation issues such as the effects of habitat loss and fragmentation on biodiversity and human-wildlife interactions and conflict in Ethiopia.  In recognition of his impact on African mammalogy, the nominee has an endemic shrew, Corcidura afeworkbekelei, named in his honor.

Dr. Louise H. Emmons is an outstanding behavioral ecologist and mammalogist, and an intrepid, some would say fearless, field biologist.  She received her Ph.D. from Cornell University (1975), but rather than pursuing a traditional academic appointment, she chose to dedicate her career to a life in the field.  She accepted a position as Research Associate in Vertebrate Zoology in the Division of Mammals at the Smithsonian Institution (1980) and has remained there throughout her career.  Her earliest research was on bats in Trinidad and tree squirrels of the West African tropics.  Dr. Emmons has since expanded her taxonomic and geographic focus to include a large variety of mammalian taxa in tropical regions around the world.

Image

Dr. Emmons has published extensively, with over 100 scientific articles and books.  Many of these contributions have become foundational references for anyone investigating those taxa. Her now-classic book on tree shrews in Asia, notably Borneo, includes data obtained first-hand on anatomy, phylogeny, behavior, and ecology, and is the first and still best in-depth study of Scandentia.  Dr. Emmons was a pioneer in the use of radiotelemetry to study large carnivores, and has published major papers and monographs on jaguars and ocelots in the Peruvian Amazon, and maned wolves in Bolivia.  These studies are remarkable for their detailed behavioral observations of these nocturnal tropical carnivores, and how felid predators can serve as keystone species affecting the community ecology of their sympatric prey.  Her field skills were so renowned that she was tapped by Conservation International to organize the mammal sections of their Rapid Biodiversity Assessments, primarily in Central and South America, for a decade.

In addition to her immersive studies of carnivores, primates, bats, and tree squirrels, Dr. Emmons has contributed greatly to our understanding of the systematics, ecology, and natural history of several groups of small mammals.  She has been particularly focused on Neotropical mammals, especially the echimyid rodents.  Her Field Guide to Neotropical Rainforest Mammals, now in its second edition, is comprehensive and the go-to reference for all mammalogists working in this region.  Most impressive of all, instead of relying on other publications, almost every entry is based on the personal experience and knowledge of the author. 

Dr. Emmons is dedicated to training the next generation of field biologists in Latin America.  She regularly includes in-country students in her research there, and always makes time to advise and mentor young mammalogists.  She is a tireless advocate for tropical conservation.  Her expeditions and research also have provided the Smithsonian with an extensive series of voucher specimens on neotropical mammals. Dr. Emmons has been called a pathfinder, and not just through the jungle at night.  The American Society of Mammalogists is proud to include Dr. Emmons as an Honorary Member.

Dr. Barry J. Fox is a community ecologist specializing in behavioral aspects of competition, fire ecology, habitat selection, factors influencing species richness, and most anything involving the ecology of small mammals, particularly Australian native rodents and dasyurid marsupials.  He received an M.S. (in Solid State Physics!) from the University of Windsor, Ontario, Canada (1972) and his Ph.D. (in Ecology) from Macquarie University, Sydney, Australia (1980).  Shortly thereafter, he became a faculty member at the University of New South Wales, where he remained until he retired in 2001.  He is still an Emeritus Professor at UNSW and continues to publish papers with deep insights from his 25 years of fieldwork.

Image

Dr. Fox has been a major contributor to the renaissance of mammalogy in Australia that began in the late 20th century.  Some of his major contributions focus on the community ecology of small mammals, especially responses to disturbances such as fire and sand mining, and to habitat fragmentation and isolation.  His extensive field work is marked by clever, rigorous experimental manipulations to test hypotheses in behavioral ecology.  For many Australian dasyurids and native rodents, he provided the first in-depth studies of their life and natural histories.  He is also widely known for exploring the concept of assembly rules in mammalian communities based on functional groups.  Dr. Fox often collaborated with small mammal researchers in North and South America to compare ideas developed in one region to data from another to evaluate the global generality of basic ecological concepts.

Dr. Fox has been an outstanding international ambassador for mammalogy.  He has played leadership roles in the Australian Mammal Society and Ecological Society of Australia, and has been a long-term member and supporter of the American Society of Mammalogists as well, promoting interactions between our two mammal societies such as joint meetings.  He served as the Australian representative on the Steering Committee of the IUBS Mammalogy Section for almost a decade, and served as Treasurer for the International Federation of Mammalogists for 24 years, playing major roles in organizing their 4-year international congresses.  Throughout his career, he has been an inspirational teacher and mentor of budding Australian mammalogists.  The American Society of Mammalogists is proud to recognize Dr. Barry J. Fox as an Honorary Member of the Society.

Dr. George B. Schaller is an eminent behavioral ecologist and conservation biologist.  He was born in Berlin, Germany, moved to the US as a teen, and completed his PhD in 1962 at the University of Wisconsin – Madison.  He has held a long list of research positions with both universities and NGOs, and currently is Vice President of Panthera and a senior conservationist for the Wildlife Conservation Society.

Image

Dr. Schaller has been described as the finest field biologist in the world.  He has conducted often ground-breaking field studies on an impressive array of mammals, including mountain gorillas, African lions, giant pandas, snow leopards, Tibetan red deer and Tibetan antelopes, Marco Polo sheep, tigers, jaguars, and Javan and Sumatran rhinoceroses. One nominator noted that Dr. Schaller appeared to thrive in field conditions that would be intolerable to most of us, selecting some of the most charismatic but also most elusive and difficult-to-study terrestrial species of mammals as the foci for his efforts.

Dr. Schaller’s research has been wide-ranging, resulting in more than 130 publications.  His top 5 publications have been cited more than 8,000 times.  Dr. Schaller strongly believes in using his research to promote conservation. His conservation efforts have helped establish 20 parks and protected areas around the world, including in the Amazon, the Hindu Kush of Pakistan, and the forests of SE Asia, Alaska (namely, the Arctic National Wildlife Refuge), as well as in China and Nepal.  In recognition of his conservation work, he received the World Wildlife Fund Gold Medal for contributions to the understanding and conservation of endangered species, and the Tyler Prize for Environmental Achievement, sometimes called the Nobel Prize for the Environment.

However, Dr. Schaller is best known for his 15 books and 5 children’s books on ecology, conservation, and natural history.  All the nominators recalled reading the nominee’s books as a young scientist.  The exploits of Dr. Schaller described in Peter Matthiesen’s book The Snow Leopard were an inspiration to many budding field biologists, and the research described in The Serengeti Lion and Golden Shadows, Flying Hooves set new standards for field ecology.  Some of his other important books include The Year of the Gorilla and The Mountain Gorilla: Ecology and Behavior; The Giant Pandas of Wolong; The Deer and the Tiger: a Study of Wildlife in India; Mountain Monarchs: Wild Sheep and Goats of the Himalaya; and Antelopes, Deer, and Relatives: Fossil Record, Behavioral Ecology, Ecology, Systematics, and Conservation.

Although Dr. Schaller’s research has focused on specific highly charismatic mammals, his approach has been comprehensive and includes consideration of the whole environment, including other species contained therein.  The research described in his books has often provided a critical foundation for all subsequent studies of these species.  Because his books were written to appeal to both scientists and non-scientists, they have enabled generations to gain a deeper appreciation of these species and their conservation needs.

As one nominator noted: “I cannot think of a single person who has contributed more to our understanding of the behavior, ecology, and conservation of so many large-bodied mammalian species.”  ASM is proud to recognize Dr. George B. Schaller as an Honorary Member of the Society.

Dr. Elisabeth S. Vrba is a mammalogist, a paleontologist, and an evolutionary biologist.  She was born in Hamburg, Germany, but grew up on a farm in Namibia where she acquired an early interest in the diversity of African bovids, in particular their often spectacular seasonal migrations. After completing a PhD at the University of Capetown, South Africa, in 1974, Dr. Vrba spent about 20 years as the Head of the Department of Paleontology and Paleoanthropology and Assistant Director of the Transvaal Museum in Pretoria, while leading two major paleontological excavations in South Africa.

Image

In 1986, Dr. Vrba accepted a position as Professor in the Dept. of Geology and Geophysics at Yale, where she soon became Curator of both Vertebrate Paleontology and Vertebrate Osteology at the Peabody Museum.  For the 20 years prior to her retirement, Dr. Vrba also directed the YIBS ECOSAVE Center, which focuses on rare and endangered mammals.  A complete list of her publications could not be located, but a section of her CV titled “Selected Publications” lists 100 items, at least a dozen of which have been cited over 300 times, with one receiving nearly 6,000 citations to date.

The focus of Dr. Vrba’s research has been bovids and hominins.  She has published many descriptions of new fossils and discussed their implications for our understanding of mammalian evolution. She has also conducted analyses of the phylogeny of ruminants – both living and fossil – particularly bovids and some tribes therein.  One nominator commented that from the 1970s to the 1990s, Dr. Vrba “almost single-handedly established the basic principles of mammalian paleoecology and the scientific basis for evaluating hominin evolution within the context of paleoclimate change.”  A lifetime of study of ruminants eventually yielded the co-authored book Antelopes, deer, and relatives: fossil record, behavioral ecology, systematics, and conservation in 2000.

Dr. Vrba is known primarily for her contributions to macroevolutionary biology, including novel ideas about the origins of mammalian diversity.  Many of these are clearly summarized in a Journal of Mammalogy paper in 1992 entitled “Mammals as a key to evolutionary theory,” which has received 425 citations. Together with Stephen J Gould, Dr. Vrba coined and promoted the term “exaptation” to describe how a trait shaped by natural selection for a particular function can become co-opted for use for a different purpose. 

Dr. Vrba is also well-known for her “turnover-pulse hypothesis,” which describes how changes in climate, through physical changes to the environment, can often result in a period of rapid extinction, migration, and appearance of new species across multiple lineages.  She tested these hypotheses with data from African antelopes and hominins.  Many of the ideas described in the turnover-pulse hypothesis are reflected in modern refugial theory.  Dr. Vrba has also proposed and tested hypotheses about species sorting versus species selection, including describing differences between ecologically generalized and ecologically specialized clades with regard to extinction and speciation rates.

On her website, Dr. Vrba commented on her own research thusly: “I prefer to push the frontiers rather than sail through tranquil, well-traveled seas.”  A distinguished nominator commented that she was “one of the greatest thinkers I have encountered in my career.”  ASM is proud to recognize Dr. Elisabeth S. Vrba as an Honorary Member of the Society.
