SAlty Science joins the ‘World’s Toughest Row’ across the Atlantic
November 21, 2023
Following 2 1/2 years of intense training and extensive preparation, a team led by a USF integrative biology professor will row 3,000 miles across the Atlantic Ocean. They push off Dec. 12 from Spain’s Canary Islands and will spend about one month at sea, rowing to English Harbour in Antigua and Barbuda.
The team, dubbed Salty Science, will compete against 40 other crews from across the world for the Talisker Whisky Atlantic Challenge – all to support training the next generation of diverse ocean scientists.
“This is a massive challenge, so it’d be crazy not to be a bit anxious about it, but mostly we’re excited to tackle it,” said Professor Chantale Bégin. “We’ve been preparing for this race and have spent so much time talking about it and thinking about it, we’re really excited to finally get going.”

Kramer Lab Awarded $3M USDA Grant
November 9, 2023
USF is one of three AAU members awarded a grant by the U.S. Department of Agriculture to investigate the transmission drivers of infectious diseases. Led by integrative biologist Andrew Kramer, the five-year study on the future of coronavirus in animals is supported by the USDA’s Animal and Plant Health Inspection Service through a multiagency partnership with the National Science Foundation and National Institutes of Health.
“With the increased interactions between humans and wildlife, one of the important things about this work is that it reminds us that it’s not just us here,” Kramer said. “Our health can also make animals sick, and that might make us sicker. And that's an understudied aspect of the dynamics.”
With a $3 million grant, Kramer will examine how the virus spreads between wildlife and humans to create predictive models that can be used to protect human health from future variants and emerging diseases.

Tampa Bay’s flamingo visitors: Everything you need to know
September 7, 2023"Why are they suddenly in Tampa Bay? ... The popular theory is that the birds, classified as American flamingos, were living in the Yucatán peninsula, heading for Cuba, got swept up in Hurricane Idalia’s winds and were pushed farther north.

That could be, said Deby Cassill, a biology professor at the University of South Florida, but another possibility is that they are not storm victims. Rather, they are storm captains.
'Flamingos are thrill-seekers, like Tom Cruise in ‘Mission Impossible,’' she said. 'They are thrilled when a big wind comes because it’s smooth sailing. They have a joyful sense of adventure, so they might have flown into the wind to see how far it could take them. They’re on vacation.'"

Why are rare tropical butterflies making a home at USF? 'They're clearly eating something'
August 17, 2023
The University of South Florida Sarasota-Manatee campus offers the perfect habitat for professors and students. It turns out a rare tropical butterfly, whose survival as a species depends on a plant in ample supply in the campus’s landscaping, likes it here, too.
In the courtyard behind the Crosley Campus Center, between the back entrance to the
rotunda and the café, visitors can see dozens of Atala butterflies – scientific name,
Eumaeus atala –fluttering among the plantings, especially the coontie (Zamia integrifolia),
which look like a palm or fern but are an ancient type of plant called a cycad (and
may be the only thing Atala caterpillars eat). The colorful butterflies – bright red-orange
abdomens and deep black wings punctuated by rows of ultramarine spots – have also
been spotted among the coontie and other landscaping on the south side of Selby Auditorium.
"They're pretty striking," said Paul Kirchman, Dean of the College of Arts and Sciences on the Sarasota-Manatee campus.
Kirchman, who had read about efforts to restore the population of Atalas elsewhere, may be partly responsible for what could be the first appearance of the Atala on the Sarasota-Manatee campus.

USF launches study abroad experience in Singapore
August 14, 2023
This summer, Ryan McCleary, an associate professor of instruction in the College of Arts and Sciences, and 23 of his students traveled over 10,000 miles to Singapore to explore the local history and culture through the lens of urban ecology.
“Singapore is often considered a zero-world country because of its advanced infrastructure,” reads McCleary’s syllabus. “Because of its size and population, it faces unique environmental pressures and has had to develop innovative means of satisfying the needs of its population while trying to maintain its biodiversity and halt environmental degradation.”
In Singapore, McCleary’s objective was two-fold: Show students there’s more than one way to do things and demonstrate the age-old proverb, “Where there’s a will, there’s a way.”
CROCODILES ROUSED TO ACTION IN A STUDY WHEN THEY HEARD RECORDINGS OF CRYING HUMAN AND APE INFANTS
August 8, 2023
In a study published Wednesday in Proceedings of the Royal Society B, researchers put speakers near crocodiles and played recordings of human, bonobo and chimpanzee infants. The crocodiles were attracted to the cries, especially shrieks that sounded more distressed...
J. Sean Doody, a conservation biologist at the University of South Florida who focuses on reptiles, said he wished the authors had found a way [to identify the sex of the crocodiles]. The information would have helped answer “perhaps the key question,” he said: “Is this response by the crocodiles predation, or is it parental?”

Survival of the seeds: USF researchers examine what it takes for trees to thrive
July 25, 2023
Assistant Professor in the USF College of Arts and Sciences, Department of Integrative
Biology, Dr. Paul-Camilo Zalamea is preparing a four-year research study on plant-soil microbial interactions, after
receiving a $1.5 million grant through the National Science Foundation (NSF).
Growing up in Bogotá, Colombia, Zalamea was surrounded by a diverse ecosystem. But
it wasn’t until he was an undergraduate student studying biology at the Universidad
de Los Andes, that his desire to pursue tropical ecology came to a head. He had the
opportunity to study in the Amazon basin, which changed his perspective and ultimately
became the reason for his research today.

‘Snakeman’ studies venomous snakes to learn more about fungal disease found in Florida
July 13, 2023When you walk into the USF St. Petersburg herpetology lab, a bold print sign reads, “Danger, venomous reptiles.” The residents inside include a venomous cottonmouth (water moccasin), two diamondback rattlesnakes, and several non-venomous water snakes. The reptiles are part of a student research project involving a fungal disease found in snakes.
Shiv Shukla, a graduate student in conservation biology, is studying the emerging pathogen Ophidiomyces ophiodiicola, which causes the snake fungal disease. The skin condition has been found in Florida and can cause abnormal molting and cloudiness of the eyes and lead to higher death rates in certain species of snakes.
Shukla, who often responds to the nickname “Snakeman” around campus because of his unique field of study, said he chose snake fungal disease as his master’s thesis because reptiles are understudied compared to other animals.

Conservation biology students forge forward this summer
June 23, 2023
The USF College of Arts and Sciences (CAS) conservation biology program aims to train the next generation of scientists who will address critical issues in biodiversity conservation.
“We recognized that there was a critical local, state and regional need for biologists with training and research experience in conservation to protect and manage our native species, communities, and ecosystems, and we created this graduate program in 2017 to address this shortage,” said Dr. Melanie Riedinger-Whitmore, St. Petersburg campus chair for the Department of Integrative Biology.
The thesis-based Master of Science program introduces students to the critical areas impacting biodiversity (habitat degradation, climate change, invasive species, pollution and over-exploitation), and provides them with the skill sets and knowledge needed for careers and research in wildlife and natural resource management and ecological restoration.
Conservation biology graduate students conduct both applied and basic research, and most students have research projects aligned with faculty research. Many students also work closely with non-profit or government agencies, and these connections help them establish important professional partnerships.

USF researchers featured in new york times article
March 21, 2023
Researchers at the University of South Florida’s St. Petersburg campus found that in a container habitat, brown widows were 6.6 times more likely to attack black widows than other related species. The behavior is likely a driver of the black widow spider’s population decline.
“We have established brown widow behavior as being highly aggressive towards the southern black widows, yet much more tolerant of other spiders within the same family,” said Louis Coticchio, who led the study as part of his undergraduate research at USF along with advisor Deby Cassill, associate professor in the Department of Integrative Biology.

USF PROFESSOR DISCOVERS NEW SPECIES WHILE PART OF TEAM STUDYING IMPACT OF OIL SPILLS IN THE GULF OF MEXICO
"Even after teaching biology for nearly three decades, Heather Judkins still gets excited about conducting field research. An associate professor of Integrative Biology on the USF St. Petersburg campus, Judkins will continue her studies of cephalopods, such as octopus and squid, on July 26 as part of a team of scientists aboard the R/V Point Sur for a 12-day research cruise around the Gulf of Mexico.
The goal of the cruise is to identify and quantify long-term trends in fishes, crustaceans and cephalopods in the midwaters of the Gulf in response to the Deepwater Horizon oil spill that occurred in 2010.
"We're collecting specimens and looking at the biodiversity in that area and how it changes over time," Judkins said. "We want to know what we could see in the future, in the unfortunate event of another oil spill."
CARNEY LAB HOSTS MAKE-A-WISH CHILD SEBASTIAN, WHO WISHED TO BE A PALEONTOLOGIST IN A LAB
Make-a Wish video link
Good Morning America video link
Sebastian is a 7-year-old who is battling cancer with ongoing chemotherapy and an
upcoming surgery. Sebastian loves all things dinosaur and has demonstrated an interest
in fossils. His passion for dinosaurs is what helps him mentally escape from his medical
challenges. Since he wants to be a paleontologist when he grows up, his greatest wish
was to experience first hand what it is like to be a paleontologist and see how they
study the prehistoric animals.
His wish day began with a limousine ride to the USF Science Center in Tampa where
Sebastian met Dr. Ryan Carney, who is a National Geographic Explorer and Assistant
Professor of Integrative Biology at USF. Sebastian was welcomed with open arms by
everyone and gifted a lab coat before embarking on a tour of the lab.
Dr. Carney said, “It’s absolutely wonderful to see the look of joy on his face. For
all of us, being able to fulfill his wish was a very fulfilling experience. It puts
things in perspective. We do this kind of stuff every day. We are fortunate to study
what we are passionate about. Being able to share that experience with Sebastian is
just wonderful.”
The newest paleontologist examined fossils and learned about the evolution of dinosaurs.
He scanned replicas of dinosaur skulls, examined mummified skin under a microscope,
and used x-ray imaging and computer animation to learn even more about prehistoric
creatures. Sebastian even 3D printed a “Sebastianosaurus” based on a Brachiosaurus
skull, his favorite dinosaur.
Sebastian’s dad said, “I’m so happy for him, especially because it opens his mind
for what he’s interested in. Seeing that everything that he can wish or dream for,
it can come true. It’s not impossible. Never give up.”

THREE GENERATIONS OF USF ACADEMICS TRAIN TO ROW ACROSS THE ATLANTIC IN SUPPORT OF MARINE CONSERVATION
Integrative Biology Professor Chantale Bégin is preparing for what is called “the world’s toughest row.” The Talisker Whisky Atlantic Challenge is an annual race to row 3,000 miles from Spain’s Canary Islands to English Harbour in Antigua and Barbuda. Bégin’s team, Salty Science, includes Lauren Shea and Noelle Helder, two of her former USF students, and Isabelle Côté, her doctoral advisor at Simon Fraser University. Salty Science is dedicating its race to marine conservation to support training the next generation of diverse scientists who will develop creative solutions to global ocean challenges.
Salty Science signed up for the challenge having no experience in rowing, but the multigenerational team of marine scientists shares a love for the water and pushing their limits. The team has a never-ending sense of adventure and is made up of certified scuba divers, licensed captains, triathlon racers and endurance runners.
“I’m stoked to combine my passion for marine conservation with some solid type II fun by rowing across the Atlantic,” said Helder, who graduated from USF in 2017. “I’m excited to be a part of this science dream team, working towards this mission with women who have inspired me throughout my career.”
BIOLOGY PROFESSOR WHO MADE MIDLIFE CAREER CHANGE GIVES $1 MILLION ESTATE GIFT TO USF ST. PETERSBURG CAMPUS
At the age of 40 and nearly 20 years into a career in health care administration, a nature documentary seismically shifted the life of Deby Cassill.
“It was a David Attenborough documentary on African wildlife, and I realized sitting there that I didn’t just want to watch science, I wanted to do science,” Cassill said.
Shortly thereafter, she went back to college to pursue an undergraduate degree in biology. By the time she was 50, she had earned a doctorate in the field and in 2001, Cassill was hired on as the first full-time biology professor on the USF St. Petersburg campus.
Cassill said the university has provided her with a wonderful opportunity to explore her passion. Now she is providing the institution with a $1 million estate gift to create the Cassill Endowed Scholarship in Biology to aid the next generation of aspiring biologists.
CARNEY LAB LAUNCHES THE GLOBAL MOSQUITO OBSERVATIONS DASHBOARD; COAUTHORS STUDY ON DINOSAUR HIPS IN THE JOURNAL NATURE
The Carney Lab just launched the Global Mosquito Observations Dashboard (mosquitodashboard.org), along with a new study about fighting mosquito-borne diseases around the world using citizen science and artificial intelligence (AI). This research is part of the lab's National Science Foundation (NSF) grant and collaboration with NASA and the CDC, and was featured on the USF homepage and NSF website. The AI techniques developed through collaboration with the Chellappan Lab include multiple patents pending, and in a follow-up student paper were also used to classify bees and bee mimics.
Dr. Ryan Carney's research on the iconic Archaeopteryx served as a key component in a Nature paper on dinosaur hip "evodevo" (evolutionary developmental biology). As covered in various media outlets, these discoveries demonstrate that the developmental changes in a bird embryo's hip over two days mirror what is seen in fossil dinosaur hips over millions of years. "In this context," remarked Carney, "the modern bird egg is a time capsule of ancient dinosaurian features."

'WILDLIFE SUSCEPTIBILITY TO INFECTIOUS DISEASES AT GLOBAL SCALE'
During the last decade many studies have investigated how different biotic and abiotic factors determine pathogen infection, particularly for zoonotic diseases affecting humans. As demonstrated by the COVID-19 pandemic, there is a need to better understand the influential factors underlying zoonotic transmission to inform future disease management strategies. Here, authors created a model using machine learning to understand the underlying environmental, geographic, and phylogenetic factors that influence zoonotic transmission. They applied it to three different host-pathogen systems: coronaviruses and bats, West Nile Virus (WNV) and birds, and malaria and birds. The results suggest that transmission of avian malaria is mostly affected by environmental distance between hosts, WNV is influenced by a combination of all three factors, while bat-coronaviruses are mostly affected by the geographic distribution of susceptible host species. The data point to bird species that are particularly susceptible to transmission, which includes songbirds and perching birds in the Passerine order. As well, several hotspot regions around the world were identified, with Eurasia being particularly susceptible to avian malaria and North America to WNV. Coronaviruses are likely to successfully invade any geographical region of the world reachable via natural dispersal or human-assisted dispersal. Results agreed with the known ecology of each analyzed system, providing a tool to discover potential host species and novel geographical hot spots for a pathogen. Thus, it can help guiding sampling decisions both in terms of host species and geographical locations. Finally, this tool can be applied at different spatial scales with few incidence data.
