National Zoo and Conservation Biology Institute (NZCBI)

Zoo and Research Center Website

Brandie Smith, John and Adrienne Mars Director

NZCBI has two campuses in the Washington, DC region. The urban campus occupies 163 acres in Rock Creek Park includes the National Zoological Park, free to the public, that features a living collection of more than 380 species (2,200 individuals) of vertebrates and invertebrates, and a large collection of native and exotic plants. NZCBI’s rural campus near Front Royal, Virginia consists of 3,200 acres of pastures, forests and meadows in the Blue Ridge Mountains, and is closed to the public. This facility is dedicated to breeding endangered species, conservation research, training and education, and is NCBI’s hub for a wide range of regional, national, and international conservation programs.

NZCBI has six Centers of Scientific Excellence: (1) Migratory Bird Center; (2) Conservation Ecology Center; (3) Center for Conservation & Evolutionary Genetics; (4) Center for Species Survival; (5) Center for Biodiversity Education and Sustainability; and (6) Animal Care Sciences. Resources available to students and visiting researchers include two veterinary hospitals; a veterinary pathology lab, nutrition labs, GIS and radiotelemetry capabilities, extensive animal holding and breeding facilities, a biodiversity genomics lab, reproductive physiology labs, libraries, conference facilities, and, in Front Royal, housing for visiting researchers and students. In addition, NZCBI has many established field sites in the United States and internationally in Thailand, Malaysia, Cambodia, China, Colombia, Gabon, southeastern Brazil, Panama, Peru, Sri Lanka, and Myanmar. Research affiliation with NZCBI entitles researchers access to other Smithsonian Institution staff, facilities and resources in an enormous range of disciplines.

Center for Conservation and Sustainability (CCS)

CCS studies and conserves biodiversity by implementing academic and professional conservation-related training programs worldwide and conducting research and monitoring activities to integrate biodiversity conservation into sustainable development. CCS goals are to provide capacity building to the next generation of conservation professionals; to provide business and industry with science-based solutions for minimizing their impact on biodiversity; and to develop innovative and strategic conservation partnerships that result in conservation solutions.

Global Health Program (GHP)

Smithsonian’s Global Health Program leverages multidisciplinary expertise in wildlife medicine, conservation ecology, training of international professionals, and investigation of emerging infectious disease to combat threats to wildlife, human, and ecosystem health worldwide. Global Health works with international partners to address risks to conservation and public health by focusing efforts at the source: the human-animal interface. The program is based upon the One Health platform, which recognizes that the health of all species is inextricably linked. As such, Global Health scientists utilize a broad range of multidisciplinary expertise (wildlife veterinarians, pathologists, epidemiologists, public health professionals, and ecologists, amongst others) to address wildlife health concerns, investigate disease at the human/wildlife interface, and conduct international training programs in an effort to build intervention and response capacity worldwide.

Migratory Bird Center (MBC)

The MBC conducts research on the ecology and conservation of migratory and resident birds. Focal areas include arctic and marine species, climate change and phenology, coffee and cacao agroforestry systems, ecosystem services, full-annual-cycle biology, grasslands, migratory connectivity, and urban ecology.

Conservation Ecology Center (CEC)

CEC is committed to sustaining animals and plants in the wild by supporting conservation scientists focusing their attention on questions that are not based on zoo collection animals. CEC works at the cutting edge of conservation science, focusing on the biology of extinction, overabundant species, nutritional ecology, endangered landscapes, and processes to measure conservation effectiveness. This work includes species from marine turtles to tigers, and ecosystems from Asian tall grass to oak forests at SCBI, where our scientists develop land- use plans as models of sustainability for our own communities.

Center for Species Survival (CSS)

CSS manages mammal and bird species in the collection at SCBI and conducts research in reproductive physiology, endocrinology, cryobiology, embryo biology, animal behavior, animal welfare, wildlife toxicology, and assisted reproduction. The mission of the CSS is leadership in the study, propagation, and research-oriented management of rare wildlife species to create knowledge that is applied to ensuring self-sustaining populations in zoos and nature.

Center for Conservation Genomics (CCG)

CCG specializes in genetic management of wild and captive populations, genomics, non-invasive DNA, ancient DNA, systematics, disease diagnosis and dynamics, genetic services to the zoo community, and application of genetics to animal behavior and ecology. It creatively applies genetic theory and methods to gain knowledge about the evolutionary and life histories of animals, to understand the importance of genetic variation to their survival, and to identify the methods needed to sustain them in captivity and the wild.

Great Plains Science Program (GPSP)

GPSP aims to study and conserve North America’s Great Plains ecosystem collaboratively, through research, restoration, and education. GPSP collaborates internally with multiple NZCBI research centers and with Smithsonian cultural and education programs, as well as externally, with tribal nations, private landowners, federal and state agencies, NGO’s and academia. Through these partnerships, GPSP applies a holistic approach to help sustain and improve this globally imperiled ecosystem’s functionality and resiliency. GPSP uses innovative approaches and advanced technology to answer important research questions on multiple facets of the ecosystem’s flora and fauna, as well as the interactions in-between, to better inform restoration practices.

Virginia Working Landscapes (VWL)

VWL aims to study and promote the conservation of native biodiversity and sustainable land management through research, education, and community engagement. In collaboration with other Smithsonian units, as well as landowners, producers, federal and state agencies, universities, and local NGO’s, VWL conducts applied research at the intersection of conservation, agriculture, and communities. Areas of focus include grassland community ecology, avian migratory connectivity, human dimensions of conservation, and restoration ecology with an emphasis on working agricultural lands. In addition, VWL works closely with community partners to co-develop programs that bridge the gap between science and conservation implementation.

Animal Care Sciences (ACS)

This research unit includes the departments of Wildlife Health Sciences, Nutrition Science, Animal Welfare, and Animal Programs. Training opportunities include internships, preceptorships, open to senior veterinary students, and residencies of varying durations for veterinarians and students from the US and abroad. Research in ACS focuses on applied and field studies in veterinary medicine, nutrition, physiology, disease etiology and management, population ecology, and animal management and welfare. ACS is also home to the National Elephant Herpesvirus Laboratory and is affiliated with the Uniformed Services University of the Health Sciences and the Armed Forces Institute of Pathology.

NZCBI has a standing Animal Care and Use Committee. Review for animal welfare concerns and approval of any animal procedures by this committee must occur before a fellow’s research can begin. Applicants must discuss their research with proposed advisors to clarify any potential issues with the Animal Care and Use process.
