Researchers from Purdue University published a study in the peer-reviewed journal Proceedings of the National Academy of Sciences indicating that a small fish that is only found in New Mexico may actually be two different species.
This could have implications for the efforts to protect and conserve this unique animal.
The White Sands pupfish is only found in four springs. Two of those populations were created by humans releasing the imperiled fish into the springs.
While it is not listed on the federal endangered species list, New Mexico considers it a threatened species and there have been efforts in the past to get the White Sands pupfish listed as endangered.
A 2009 petition cites threats to the White Sands pupfish as exotic ungulates like the introduced oryx, missile-firing activity, water withdrawal and the invasive salt cedar plants.
The genetic research indicates that the pupfish from the Salt Creek population were taken and released to create the Lost River and Mound Spring populations.
The fourth population—found in Malpais Spring—is genetically distinct from the other three populations due to a phenomenon known as genetic drift. Essentially, about 5,000 years ago, the Carrizozo lava flow separated the Malpais Springs pupfish from the Salt Creek pupfish. Because of that separation, the two populations diverged genetically and became different species.
Andrew Black, a study co-author, said the researchers knew there were two distinct populations—or evolutionarily significant units—with different genetics when they went into the study process. But they discovered that the genetics are so different that the pupfish found in Malpais Springs is essentially a different species.
“The separation between samples from these two ESUs was huge!” Black said in a response to questions from NM Political Report. “The point was driven home when we looked at how differentiation between these two ESUs occurred across the entire genome. We were expecting relatively low levels of differentiation, with perhaps several peaks of high differentiation associated with genes underlying local adaptations, but instead we saw an extremely high background of differentiation across the entire genome. This, I believe, is when we decided we needed to change our study design from looking at two populations of one species to two different species.”
Black had previously researched the Leon Springs pupfish during his graduate studies before he went to work on postdoctoral research at Purdue University with Professor J. Andrew DeWoody.
“I was excited to work with pupfish again,” Black said in an email response to questions from NM Political Report. “For fish, they really are pretty charismatic.”
Black described them as “small chunky fish, with cool behavior and male nuptial coloration.” He said the “discrete desert springs they typically live in makes for a really interesting model.”
And, Black said, he’s always been interested in using genetics and genomics as a tool to protect and conserve imperiled species.
Black and his team have proposed calling the pupfish found in Salt Creek, Lost River and Mound Spring the enchanted pupfish—a reference to New Mexico being known as the Land of Enchantment. Meanwhile, they propose keeping the name White Sands pupfish for the Malpais Spring population.
But, before the enchanted pupfish can be officially declared a different species, other scientists need to concur.
Mike Ruhl, the assistant chief of the research and management section for the New Mexico Department of Game and Fish’s Fisheries Management Division, said that the state is aware of the research project and the recent paper.
“White Sands Pupfish occur entirely on U.S. Department of Defense lands and are managed through a Conservation Team that includes White Sands Missile Range, Holloman Air Force Base, the U.S. Fish and Wildlife Service and the Department,” Ruhl said in a statement. “Given its very recent publication, the management implications of the article are currently unclear and adoption of new fish species designations is a function of the Committee on Names of Fishes, a joint committee of the American Fisheries Society and the American Society of Ichthyologists and Herpetologists. The White Sands Pupfish Conservation Team will consider the research and its implications at its next meeting.”
WildEarth Guardians was behind the 2009 petition to have the pupfish listed as endangered, but it is unclear how the organization will respond to the study.
Joanna Zhang with WildEarth Guardians anticipates that the new study will have an impact.
Zhang said that if the pupfish is indeed two separate species, it means that the population found in Malpais Spring has no duplicate population. If something were to happen to Malpais Spring, the pupfish could be lost entirely. A refuge population could help provide some assurance that the rare pupfish could survive long into the future through human intervention, but, Zhang said, “ideally you don’t lose the population that’s out in the wild.”
The study also has other implications for conservation.
“Making sure that both of them have a robust population that has enough genetic diversity to remain viable in the long term, is really important,” Zhang said.
Black said that previous research and current genetic diversity estimates indicate that the White Sands pupfish has little genetic diversity.
“We showed that the genetic diversity levels of these fish are substantially lower than many other related species, close to the levels observed in several inbred lines of laboratory fish,” he said. “This is problematic as diversity is a good proxy of fitness and helps buffer environmental change.”
He said continued efforts to “ensure effective gene flow between populations of the same species” as well as conservation efforts to maintain good breeding habitat for the pupfish could help protect the genetic diversity that currently exists.
And researchers aren’t done examining the White Sands pupfish and its genetics.
One of Black’s co-authors, Erangi Heenkenda, has been sequencing the genomes of the White Sands pupfish overtime. This has involved taking genetic samples at two different time points approximately 18 years apart to examine how the species are changing.
Black said Heenkenda’s research should “be informative of the evolutionary processes occurring at a more contemporary time scale.”

Think New Mexico is New Mexico’s think tank – a results-oriented think tank whose mission is to improve the lives of all New Mexicans, especially those who lack a strong voice in the political process. It fulfills this mission by educating the public, the media, and policymakers about some of the most serious challenges facing New Mexico and by developing and advocating for enduring, effective, evidence-based solutions.
Its approach is to perform and publish sound, nonpartisan, independent research. Unlike many think tanks, Think New Mexico does not subscribe to any particular ideology. Instead, because New Mexico is at or near the bottom of so many national rankings, its focus is on promoting workable solutions that will lift all New Mexicans up.
Consistent with its nonpartisan approach, Think New Mexico’s board is composed of Democrats, Independents, and Republicans. They are statesmen and stateswomen, who have no agenda other than to see New Mexico succeed. They are also the brain trust of this think tank.
Think New Mexico began its operations Jan. 1, 1999. It is a tax-exempt organization under section 501(c)(3) of the Internal Revenue Code. In order to maintain its independence, Think New Mexico does not accept state government funding. However, contributions from individuals, businesses, and foundations are encouraged, appreciated, and tax-deductible.
As an independent, statewide, results-oriented think tank, Think New Mexico measures its success based on changes in law or policy that it helps to achieve.
Think New Mexico’s results include:
- Making full-day kindergarten accessible to every child in New Mexico;
- Repealing the state’s regressive tax on food and successfully defeating efforts to reimpose it;
- Creating a Strategic Water Reserve to protect and restore New Mexico’s rivers;
- Establishing New Mexico’s first state-supported Individual Development Accounts to alleviate the state’s persistent poverty;
- Redirecting millions of dollars a year out of the state lottery’s excessive operating costs and into college scholarships
- Reforming title insurance to reduce closing costs for homebuyers and homeowners who refinance their mortgages
- Winning passage of three constitutional amendments to professionalize and streamline New Mexico’s Public Regulation Commission
- Modernizing the state’s regulation of taxis, limos, shuttles, and moving companies
- Creating a one-stop online portal to facilitate business fees and filings
- Establishing a user-friendly health care transparency website where New Mexicans can find the cost and quality of common medical procedures at any hospital in the state
- Enacting the New Mexico Work and Save Act to make voluntary state-sponsored Individual Retirement Accounts accessible to New Mexicans who lack access to retirement savings through their jobs;
- Making the state’s infrastructure spending transparent by revealing the legislative sponsors of every capital project;
- Ending predatory lending by reducing the maximum annual interest rate on small loans from 175% to 36%;
- Repealing the tax on Social Security for middle and lower-income New Mexicans with incomes under $100,000 as individuals or $150,000 as married couples;
- Enhancing the training and transparency of local school boards;
- Leading a campaign to make financial literacy a high school graduation requirement, now in place in 46 districts reaching nearly 48% of New Mexico students; and
- Establishing a $2 billion permanent trust fund for Medicaid.
Think New Mexico is headquarters in the historic Greer House at 505 Don Gaspar in Santa Fe, at the corner of Paseo de Peralta and Don Gaspar, directly across the street from the state Capitol. To learn more, visit thinknewmexico.org.
