Scientists collect and freeze biological materials, such as gametes, tissue, milk and DNA

The sliminess on amphibians is more than just goop—it’s how these animals survive. A scientist and intern from the Smithsonian’s National Zoo and Conservation Biology Institute’s Center for Conservation Genomics explains.
In conservation genomics, we study the building blocks of life, like DNA.

When Echo’s five cubs were born last fall, their exact parentage was a mystery. A genetic analysis conducted by Smithsonian scientists revealed the truth.
collected blood samples from each cub during a routine veterinary exam, and the DNA

Smithsonian scientists are working to uncover the earth’s incredible diversity of microorganisms and to understand how they impact plant, animal and ecosystem health.
With new DNA and RNA technologies, scientists can identify and characterize a vast

Sometimes, science stinks — literally! In Montana, researchers are setting up “scat traps“ to attract swift foxes, so they can learn from the droppings the foxes leave behind.
Scat contains DNA and hormones, which can reveal a lot about the animal that left

Rob Fleischer is research associate and former head of the Smithsonian Conservation Biology Institute’s Center for Conservation Genomics. His primary fields of interest are evolutionary and conservation biology. He conducts individual and collaborative research in population and evolutionary genetics, systematics, and molecular and behavioral ecology, mostly on free-ranging bird and mammal species, and their pathogens. Many of his recent projects use genomic, transcriptomic and microbiome methods. Fleischer has particular interest in:
Fleischer has particular interest in: the use of ancient DNA methods to document

Jesus Maldonado has been a research geneticist at the Center for Conservation Genomics at the Smithsonian’s National Zoo and Conservation Biology Institute (SCBI) since 1998. His research applies molecular genetics tools to answer basic and applied questions in conservation and evolutionary biology in mammals. Much of his research involves assessment of genetic variation within and among populations and species to document levels of inbreeding and determine units of evolutionary, taxonomic and conservation significance.
years, he has developed and utilized non-invasive genetic techniques and ancient DNA

Prehensile-tailed porcupines, also called coendous, are one of 12 species of New World porcupines. They are native to South America, where they live in trees and eat fruits.
Smithsonian’s National Zoo scientists use the innovative technique of analyzing DNA

As the year winds down, we’re reflecting on some of our biggest conservation success stories of 2019.
The rehydrated tissues maintained their structure and basic functions, including DNA

Smithsonian scientists and partners believe genetic diversity could hold the key to saving amphibians from Ranavirus, a pathogen that is particularly devastating to frogs and toads in the U.S.
