Neglecting museum specimen is dangerous for science

In a dusty room in central Florida, numerous millipedes, centipedes, and different creepy-crawlies take a seat in specimen jars, rotting. The invertebrates are a part of the Florida State Selection of Arthropods in Gainesville, which totals greater than 12 million bugs and different arthropod specimens, and are utilized by professional curators to spot pest species that threaten Florida’s local and agricultural crops.

Alternatively, no longer all specimens on the facility are handled similarly, consistent with two individuals who have observed the gathering firsthand. They are saying non-insect samples, like shrimp and millipedes, which are saved in ethanol were ignored to the purpose of being irreversibly broken or misplaced utterly.

Relating to how the FSCA stacks up with different collections she’s labored in, Ann Dunn, a former curatorial assistant, is blunt: “That is the worst I’ve ever observed.”

Professionals say the lack of such specimens—even uncharismatic ones comparable to centipedes—is a setback for science. In particular precious are holotypes, which might be the instance specimens that resolve the outline for a complete species. In reality, the number of holotypes a set has is continuously extra essential than its dimension, since the ones specimens are actively used for analysis, mentioned Ainsley Seago, an affiliate curator of invertebrate zoology on the Carnegie Museum of Herbal Historical past in Pittsburgh.

A paper printed in March 2023 highlighted the significance of museum specimens extra most often, for addressing pressing problems like local weather alternate and natural world conservation, with 73 of the arena’s biggest herbal historical past museums estimating their overall collections to exceed 1.1 billion specimens. “This world assortment,” the authors write, “is the bodily foundation for our working out of the flora and fauna and our position in it.”

Thru Aaron Keller, the communications director of the Florida Division of Agriculture and Client Products and services—which oversees the FSCA—the museum declined to talk with Undark for this tale. In accordance with a grievance that Dunn filed with the FDACS Place of business of Inspector Common, the director of the museum’s mother or father company Trevor Smith wrote: “clinical specimens don’t want to be pristine or absolute best specimens” and “museum group of workers try to care for fabrics in the most efficient situation conceivable as a result of they can’t be changed.”


Dunn set to work on the Florida State Selection of Arthropods in April 2022 as an assistant to curator Felipe Soto-Adames. She used to be to begin with employed, she informed Undark in a contemporary interview, partially to assist care for a part of the FSCA’s assortment—one of the so-called rainy specimens, or invertebrates saved in vials and jars full of alcohol. However she mentioned she used to be stunned when she noticed the situation of lots of the specimens that have been meant to be beneath her care. (The FSCA didn’t reply to a request for touch upon Dunn’s hiring or specifics about her position, nor did the museum reply to a couple of requests for an interview with Soto-Adames.)

Dunn informed Undark that she discovered delicate specimens sitting in brown ethanol, some with stoppers so eroded that they have been dripping a waxy substance onto the contents of the vial. Many of the injury is within the selection of non-insect arthropods, like solar spiders, millipedes, and shrimp. She estimates that part of the FSCA’s ethanol assortment, which integrated 200,000 vials and roughly 1.1 million person arthropods as of 2022, is broken or rotten. Someone else who’s aware of the FSCA collections agreed with Dunn’s review. (They requested to stay nameless, bringing up concern of retaliation.)

The FSCA used to be based in 1915 to accommodate the selection of the Florida State Plant Board (now the Department of Plant Trade), and merged with different state collections within the Sixties after the Florida Division of Agriculture and Client Products and services officially took it over. These days, the FSCA seeks “to construct the most efficient conceivable international selection of terrestrial and aquatic arthropods in make stronger of analysis, schooling and the purposes of the Florida Division of Agriculture and Client Products and services,” consistent with its site.

The state of the gathering, Dunn mentioned, avoided her from satisfying the FSCA’s challenge of figuring out pest species. When other folks requested the museum for assist figuring out garden shrimp—terrestrial crustaceans which are invasive in Florida—Dunn needed to depend on Google Photographs. “I knew from enjoy that the gathering would no longer assist me in any respect,” she mentioned, because of a loss of group and degradation of specimens.

Keeping up any such huge assortment isn’t simple, in particular relating to specimens preserved in alcohol. Whilst a couple of establishments have well-managed alcohol collections, many others don’t, mentioned Seago of the Carnegie Museum of Herbal Historical past. (Seago could also be president of the Entomological Collections Community, a nonprofit that gives absolute best practices for insect and different arthropod collections.) She demonstrated one such problem in a Zoom interview, maintaining up jars of crabs that have been bone dry—the entire alcohol inside of had evaporated over the years. Whilst hard-bodied crabs can stay intact when desiccated, soft-bodied invertebrates fare worse. And evaporating alcohol too can degrade the stopper used to seal the specimen’s container, particularly if it’s made from cork or rubber.

On the Carnegie Museum of Herbal Historical past, there are roughly 76,000 packing containers of ethanol specimens, most commonly saved in a Global Battle-II-era Quonset hut, which is comprised of corrugated metal and is uninsulated. In keeping with Seago, replenishing the specified ethanol of each and every pattern takes a large number of paintings. Although interns or volunteers are to be had to move thru all of them, supervisors need to oversee the method to make sure they’re the use of the proper alcohol focus and know how the specimens must be correctly arranged.

“Simply holding an alcohol assortment at baseline ‘ok’ is a huge quantity of effort,” Seago mentioned.


According to Dunn, her paintings on the Florida State Selection of Arthropods got here to a halt when her one-year contract used to be no longer renewed in April, simply days after she posted destructive feedback in regards to the place of business habits of head curator Paul Skelley on her private, nameless Twitter account. Dunn had submitted a proper grievance in opposition to Skelley and the state of the ethanol collections to the FDACS Place of business of Inspector Common on April 17. The inspector common’s administrative center made up our minds that Dunn’s grievance didn’t warrant an investigation, and in a written analysis, they famous that Dunn used to be let opt for “behavior unbecoming a public worker and insubordination related to derogatory feedback posted on social media.”

Following her firing, Dunn tweeted pictures of broken specimens from the FSCA’s assortment. Jackson Method, a millipede taxonomist on the Virginia Museum of Herbal Historical past, informed Undark he had handiest observed equivalent stipulations in an alcohol assortment that have been left unattended in a warehouse for 22 years. “Those pictures are undoubtedly long-term forget,” he mentioned.

One of the crucial ignored specimens integrated holotypes, Dunn informed Undark. The lack of holotypes can motive uproar some of the clinical group, however they are able to get replaced—if any individual is going during the effort of officially describing a neotype (a brand new holotype intended to interchange one who has been misplaced or broken). However designating a neotype “generally will depend on people with the ability to resolve whether or not or no longer you’ll discover a specimen of the similar species from the similar locality” because the holotype, mentioned Seago. For lots of species, there aren’t sufficient mavens to do this paintings, she mentioned, “and the less taxonomists you’ve got for that team, the fewer most likely this is.”

Seago is recently making use of for a grant to assist find, consolidate, and digitize holotype specimens on the Carnegie Museum of Herbal Historical past. And Method mentioned the Virginia Museum of Herbal Historical past is operating to catalogue its holotypes too. Dunn have been running on a equivalent organizational enterprise on the FSCA prior to her firing.


Many creditors, from scientists to hobbyists, donate their private collections to museums. This used to be the case for Nell Causey, who had her millipede assortment given to the FSCA after her dying in 1979. Causey earned a Ph.D. from Duke College in 1940, and used to be “the most important myriapodologist of her time,” mentioned Method. “She used to be a actually just right collector, and he or she described a large number of species.”

All over Dunn’s efforts to assist catalogue the FSCA’s holotypes, she says she discovered 8 of Causey’s millipedes sitting mislabeled on a shelf within the incorrect development accumulating mud. The samples have been described in 2010 through William Shear, a professor emeritus at Hampden-Sydney School in Virginia, who had borrowed the specimens a number of years prior for a analysis challenge. Neither Dunn nor her coworker at the challenge knew they existed prior to Shear reached out to test on them. (Shear informed Undark that this snafu used to be led to through a loss of conversation from the former curator, and he has since borrowed and deposited specimens on the FSCA with out a issues.)

Dunn is concerned that the lifestyles’s paintings of Causey and different passionate creditors, like arachnid specialist Martin Muma, who died in 1989, is vulnerable to degradation on the FSCA, particularly with out devoted taxonomists to take care of them. This can be a disgrace, Method informed Undark, to lose portions of a distinguished collector’s paintings. “Possibly artwork historians might be mad at me, however it’s so much just like the degradation of a portray,” he mentioned. “You might be dropping a work of historical past.”

Many museum curators have a choice or bias for the particular team they paintings on, mentioned Seago, and can prioritize take care of that team—particularly in the event that they’re in a set the place “the folks in rate don’t care in any respect about the ones teams.” In the meantime, taxonomists can also be demanding to come back through, and he or she mentioned that is even more true for small, difficult to understand, and uncharismatic teams of organisms. Dunn mentioned this taxonomic bias used to be sturdy at FSCA, which particularly favors beetles. The individual aware of the museum’s collections who didn’t want to be named agreed with Dunn that there’s a chronic angle of favoritism towards charismatic bugs at FSCA.

Museum donors additionally generally have personal tastes for sure teams—Seago mentioned she may just simply elevate budget for a brand new butterfly cupboard—however herbal historical past museums want extra money in the event that they’re going to adequately take care of their whole collections. That hasn’t at all times been the case even for extra standard creatures. “Investment has been shedding around the board,” mentioned Method. “And as a result of that, staffing is down.”

Dunn accepts the commonality of forget in ethanol collections, however mentioned “that doesn’t make it applicable.” And relating to holotypes, she mentioned, there’s no excuse. “Holotypes must by no means cross with out care.”

Method and Seago agreed. “The entire level of a museum,” mentioned Method, is to deal with sort specimens “in perpetuity.”
