GAINESVILLE, Fla. — The Florida Museum of Natural History recently announced the winners of the 2015 Austin Award and Bullen Award for superior research and significant contributions to the development of museum collections and programs.
Vertebrate paleontology graduate assistant Catalina Pimiento received the Austin Award for her research on the ecology of shark species throughout history, particularly Carcharocles megalodon.
Anthropology graduate student Zackary Gilmore received the Bullen Award for his research to determine the scale of social interactions involved in the construction and use of the Silver Glen Springs shell mound site in the Late Archaic period (about 5,000 to 3,000 years ago).
To gain insight into conservation of modern sharks, Pimiento closely investigates factors involved in the extinction of megalodon, including body size and distribution trends over time.
In her previous research conducted under the guidance of Florida Museum vertebrate paleontology curator Bruce MacFadden, Pimiento studied shark species from Panama to better understand marine connections during the formation of the isthmus. She found that sharks used shallow-water nursery areas for millions of years as an adaptive strategy for survival. This study has received nationwide media attention, including the National Geographic documentary film “Clash of the Americas.”
MacFadden said he nominated Pimiento for “her excellence in paleontological research and (more…)
GAINESVILLE, Fla. — In the 65-million-year-old arms race between bats and moths, some moth species rub their genitals to jam the calls of bats. Radar jamming is commonly used in human warfare, allowing pilots to render themselves invisible. By unraveling the evolution of hawkmoths’ similar defense, authors of a new study appearing online this week in the Proceedings of the National Academy of Sciences aim to better understand nocturnal biodiversity and improve human uses of sonar.
Study researchers with the University of Florida and Boise State University tracked sonar jamming throughout the evolutionary history of hawkmoths and found that one of the insect world’s most sophisticated defense mechanisms is more widespread than originally thought, existing for millennia.
Until now, the function and evolution of sonar jamming remained largely a mystery, said lead author Akito Kawahara, assistant curator of Lepidoptera at the Florida Museum of Natural History on the UF campus.
“Before now people thought ultrasound usage in insects was very restricted to certain groups, but it looks much more complex than that,” Kawahara said.
Kawahara and collaborators scoured jungles and forests from Borneo to the Amazon observing hawkmoths. They collected specimens at 70 sites in 32 countries and conducted field-based echolocation experiments and (more…)
GAINESVILLE, Fla. — The Florida Museum of Natural History recently recognized its 2015 volunteers of the year, including a new student award winner.
Russell Henderson and Gerald Kidder were named winners of the James Pope Cheney Volunteer of the Year Award, and Crystal Coleman was recognized with a newly formed Student Volunteer of the Year Award. The Florida Museum recognized the winners during its annual volunteer reception April 1.
Winning in the exhibits and public programs division, Henderson served 220 hours during 2014 and has completed more than 1,454 hours at the museum since he began volunteering in 2008 as a docent. He is known by his colleagues to attend a variety of museum programs to further his knowledge, help visitors dig deeper into a topic and keep others informed of new ways to become effective docents.
“Russell’s easygoing approach with museum visitors is one of his most valuable assets,” wrote Florida Museum school programs coordinator Dianne Behringer in her nomination letter. “I very regularly observe laughter and smiles as I pass by Russell and his group.”
Awarded for his work in research and collections, Kidder served 145 hours during 2014 and (more…)

GAINESVILLE, Fla. — The Florida Museum of Natural History’s Randell Research Center on Pine Island near Fort Myers, once home to the Calusa Indians, has acquired an additional five acres containing two mounds. The area will eventually be added to the site’s educational interpretive trail.
Museum officials plan to formally announce the purchase at 9:30 a.m. on Monday (March 16) at the Calusa Heritage Trail, 13810 Waterfront Drive, Pineland, 33945.
The addition of a burial mound and ancient midden to the now 67-acre site was made possible with a $150,000 gift from the Sear Family Foundation and $50,000 from the Calusa Land Trust.
“This is a dream come true,” said Randell Center director William Marquardt, who will make the formal announcement Monday. “Since the original gift of property by the Randell family in 1996, we have wanted to add these mounds to the area that we protect and (more…)
GAINESVILLE, Fla. — Visitors can discover 70 million years of climate change on Earth in a new exhibit now open at the Florida Museum of Natural History.
The “Our Changing Climate: Past and Present” exhibit uses large-format graphs showing major historic events to present the story of Earth’s changing climate over geologic time. The exhibit also highlights how Earth’s climate fluctuates and what global trends are affecting life today.
Opened Wednesday, this free exhibit is the first in a series of exhibits focusing on world issues that influence humans’ daily lives.
“In this series of exhibitions, we hope to engage visitors in a conversation by looking at how science explores the issues and how it can help us navigate ways to correct course or cope with new realities,” said Darcie MacMahon, the museum’s head of exhibits and public programs.
Some of the issues to be presented in future displays are especially important for Floridians, such as sea level rise and (more…)

GAINESVILLE, Fla. — Tropical turtle fossils discovered in Wyoming by University of Florida scientists reveal that when the earth got warmer, prehistoric turtles headed north. But if today’s turtles try the same technique to cope with warming habitats, they might run into trouble.
While the fossil turtle and its kin could move northward with higher temperatures, human pressures and habitat loss could prevent a modern-day migration, leading to the extinction of some modern species.
The newly discovered genus and species, Gomphochelys (pronounced gom-fo-keel-eez) nanus – provides a clue to how animals might respond to future climate change, said Jason Bourque, a paleontologist at the Florida Museum of Natural History at UF and the lead author of the study, which appears online this week in the Journal of Vertebrate Paleontology.
The wayfaring turtle was among the species that researchers believe migrated 500-600 miles north 56 million years ago, during a temperature peak known as the Paleocene-Eocene Thermal Maximum. Lasting about 200,000 years, the temperature peak resulted in significant movement and diversification of plants and animals.
“We knew that some plants and lizards migrated north when the climate warmed, but (more…)
GAINESVILLE, Fla. — In the cover of night, an unseen war between bats and moths has been raging for 60 million years—and a new study suggests the insects have evolved long tails as a defense.
The collaborative work between University of Florida and Boise State University researchers is a first step in determining why bats are lured into striking a false target and could have implications on sonar development for the military, said study co-author Akito Kawahara, assistant curator of Lepidoptera at the Florida Museum of Natural History on the UF campus.
“This finding expands our knowledge of anti-predator deflection strategies and the extent of a long-standing evolutionary arms race between bats and moths,” Kawahara said.
The study appearing today in the Proceedings of the National Academy of Sciences shows luna moths spin their long hindtails as they fly, confusing the sonar cries bats use to image prey and other objects. Diversionary tactics, such as false eye spots and (more…)
