GAINESVILLE, Fla. — Sharing caves with millions of bats, the Caribbean’s first humans may have driven some species of the winged mammals to extinction.
The new study appearing online today in Scientific Reports rejects previous research that directly connected climate change and the loss of land with the disappearance of bat populations.
Knowing when and how Caribbean bats went extinct could contribute to better understanding biodiversity and how to save modern-day wildlife from meeting the same fate, said co-author David Steadman, a University of Florida ornithologist.
“Ours are the first radiocarbon dates for bat fossils in the whole West Indies,” said Steadman, curator of ornithology at the Florida Museum of Natural History on the UF campus. “The new dates prove that certain bat populations were still in existence much later than previously thought — around the same time humans arrived.”
The new dates demonstrate that at least five species of bats withstood this climate change and (more…)
GAINESVILLE, Fla. — Say “primate” and most people wouldn’t think of a tree-dwelling, squirrel-like creature that weighs no more than a deck of playing cards, but a new study suggests that may perfectly describe humans’ earliest primate ancestors.
Found in the same area of Montana that yielded the massive Tyrannosaurus rex, new ankle bones smaller than a penny provide the first fossil evidence that the oldest primates lived in trees.
That’s important because living in trees gave those early primates access to food sources that other species lacked – likely a critical factor in why primates succeeded in evolution where others may have failed.
The study appearing this week in the online edition of the Proceedings of the National Academy of Sciences describes the first bones below the skull of Purgatorius—previously known only by its teeth. The shape of the teeth allowed paleontologists to determine the tree shrew-like animal ate insects and (more…)

GAINESVILLE, Fla. — A new study involving more than 100 researchers from 10 countries, including the University of Florida, has reconstructed the insect tree of life and found, among other things, that insects ruled the land 400 million years ago.
The cover story in Friday’s issue of the journal Science answers many long-held questions about the evolution of the world’s largest and most biodiverse group of animals, information essential to understanding the millions of living insect species that shape our terrestrial living space and support and threaten our natural resources.
The new tree of life incorporated many fossils, making it the first dated evolutionary tree of this magnitude, said co-author Akito Kawahara, assistant curator of Lepidoptera at the Florida Museum of Natural History on the UF campus, who leads the butterfly and moth initiative for the ongoing project.
“Until now, we didn’t have a good understanding of how these diverse groups of insects are related to each other,” “Until now, we didn’t have a good understanding of how these diverse groups of insects are related to each other,” said Kawahara, a researcher in the McGuire Center for Lepidoptera and Biodiversity, which holds one of the world’s largest collections of butterflies and moths. “Many insects important to everyday life and scientific research were included in the study, (more…)
GAINESVILLE, Fla. — One man’s trash will be another man’s treasure during the 16th annual Trashformations student recycled art competition awards ceremony at the Florida Museum of Natural History from 5:30 to 8 p.m. Nov. 21.

GAINESVILLE, Fla. — It’s written in the stars that Florida Museum of Natural History visitors will have an opportunity to observe the universe with astronomy experts during the eighth annual Starry Night from 6 to 10 p.m. Nov. 14.
Visitors can stargaze during a planetarium show and with professional-quality telescopes provided by area astronomists at this free, family-friendly event. A 3-D “AstroWall” will also allow visitors to view the cosmos in another dimension.
Representatives from the Alachua Astronomy Club, Santa Fe College natural sciences department’s astronomy program, the Kika Silva Pla Planetarium and UF astronomy department will help visitors uncover the mysteries of the night sky.
“I think people love space because it is something we are completely surrounded by but also something most of us have never experienced first-hand,” said Florida Museum educator Amanda Harvey. “We’re really lucky to have an opportunity like Starry Night where people that specialize in the field come together to share what they’ve learned and are learning to help us understand space and to make it more familiar.”
The event features UF astronomy department professor Fred Hamann who will discuss “Quasars and Black Holes: A Journey Toward the Gravitational Abyss.”
Attendees will earn a prize by tracking their activities with a “Passport to the Universe.” They also have an opportunity to dine under the stars by visiting the event’s food vendor, High Springs Orchard and (more…)
GAINESVILLE, Fla. — A new University of Florida study dismisses claims that megalodon is still alive by determining a date of extinction for the largest predatory shark to ever live.
Researchers from UF and the University of Zurich hope the study appearing online today in the journal PLOS ONE showing the species became extinct 2.6 million years ago will clarify public confusion. The study may also one day help scientists better understand the potential widespread effects of losing the planet’s top predators, said lead author Catalina Pimiento.
“I was drawn to the study of Carcharocles megalodon’s extinction because it is fundamental to know when species became extinct to then begin to understand the causes and consequences of such an event,” said Pimiento, a doctoral candidate at the Florida Museum of Natural History on the UF campus. “I also think people who are interested in this animal deserve to know what the scientific evidence shows, especially following Discovery Channel specials that implied megalodon may still be alive.”
The study represents the first phase of Pimiento’s ongoing reconstruction of megalodon’s extinction. As modern top predators, especially large sharks, are significantly declining worldwide due to the current biodiversity crisis, Pimiento said this study serves as the basis to better understand the consequences of these changes.
“When you remove large sharks, then small sharks are very abundant and they consume more of the invertebrates that we humans eat,” Pimiento said. “Recent estimations show that large-bodied, shallow-water species of sharks are at greatest risk among marine animals, and (more…)
GAINESVILLE, Fla. — Boy Scouts and Girl Scouts are invited to get a closer look at the natural world by participating in their next adventure at the Florida Museum of Natural History.
