In aquatic ecosystems, some species use active sensing systems, emitting echolocation sounds or electric fields to navigate dark or murky waters.

This sensory ability can come with trade-offs. For electric eels and their weakly electric knifefish prey, generating electric fields helps them navigate and hunt, but those same signals can also reveal their location.

In a recent study published in , 麻豆原创 researchers found that both electric eels and knifefish strategically suppress and resume their electric signals to avoid detection.

The findings provide new insight into how animals balance sensing their surroundings while remaining hidden from predators or prey, a challenge that also appears in technologies such as sonar and radar. This work also expands scientific understanding of how active sensory systems evolve in competitive environments where being detected can mean losing a meal or becoming one.

鈥淥ur findings show that active sensing creates a paradox: the same electric signals these animals need to navigate and hunt can also reveal them to eavesdropping predators or prey,鈥� says Professor of Biology William Crampton, who co-led the study with biology doctoral graduate Lok Poon 鈥�26PhD. 鈥淏oth eels and knifefish appear to resolve this paradox through electric stealth, briefly suppressing their signals when concealment matters, then resuming them when sensing becomes more important.鈥�

Tracking Electric Signals in the Amazon

To test these predator-prey interactions, the researchers deployed six custom-designed electric signal loggers along a 150-meter section of an Amazonian stream. Each logger recorded 60-second segments of electric signals over 27 nights. In total, nearly 107,000 minutes of data were collected.

鈥淓lectric fish are ideal for this kind of study because their signals let us monitor their presence and movements electronically, simply by recording how often they pass near submerged electrodes,鈥� Crampton says. 鈥淥ur loggers allowed us, for the first time, to monitor predator-prey electric signaling interactions continuously in the wild.鈥�

Researchers then analyzed the recordings to distinguish species by their unique electric signal signatures.

How Eels and Knifefish Use 鈥淓lectric Stealth鈥�

“With knifefish, we found that when they detect electric eel signals, some flee while some pulse-type species switch off their own electric discharges for several seconds. “鈥擶illiam Crampton, professor of biology

鈥淲ith knifefish, we found that when they detect electric eel signals, some flee while some pulse-type species switch off their own electric discharges for several seconds,鈥� Crampton says. 鈥淚n our logger recordings, a knifefish could be producing its normal train of pulses to sense its environment, then suddenly become electrically silent as soon as eel signals appeared.鈥�

Laboratory tests showed that low-frequency components of electric eel signals play a key role in triggering this response, with knifefish reacting far less when those components were reduced.

Electric eels were also found to pause their low-voltage electrolocation pulses before high-voltage bursts used to probe for or stun prey. This silence would make an approaching eel less detectable to electroreceptive prey such as knifefish. Once the eel produces a high-voltage burst, however, it has revealed its presence, temporarily reducing the benefit of stealth. 聽The eel promptly resumes its regular low-voltage pulses, likely to rapidly relocate, track or capture prey.

鈥淭丑别 field recordings revealed these phenomena in the ecological context,鈥� Crampton says. 鈥淭丑别 laboratory experiments then allowed us to isolate the eel signal features that trigger knifefish responses.鈥�

Parallels in Nature and Technology

In nature, the only well-studied comparison to this behavior is the predator-prey dynamic between killer whales and their toothed-whale prey.

鈥淜iller whales and smaller toothed whales such as beaked whales use echolocation, relying on sound rather than electric signals to sense their surroundings,鈥� Crampton says. 鈥淢ammal-eating killer whales can suppress echolocation and calls while hunting, while beaked whales and other prey species may reduce vocal activity or take evasive action when they detect killer whale sounds. The eel-knifefish system shows a remarkably similar trade-off in the electric sense.鈥�

The findings suggest convergent evolutionary pressures favoring the ability of both predators and prey to modulate active-sensing signals to improve survival.

Similar trade-offs also occur in human active-sensing technologies such as sonar and radar. A submarine, for instance, can use active signals to detect its surroundings, but each outgoing ping can also reveal the vessel鈥檚 location.

鈥淛ust as we found in electric eels and knifefish, operators of these systems balance the need to gather information with the need to remain hidden,鈥� Crampton says. 鈥淚n submarines, that can mean alternating between active sonar and passive listening depending on the situation.鈥�

Electric eels, knifefish, echolocating whales and human operators all face the same challenge: balancing the benefits of active sensing with the risk of detection.

Future Research Applications

Electric fish have long contributed to scientists鈥� understanding of concepts beyond biology, including electricity, nerves and sensing.

鈥淓lectric fishes have played an outsized role in the history of biology and physics,鈥� Crampton says. 鈥淔or example, their discharges helped shape early research on electricity, including Alessandro Volta鈥檚 invention of the first battery, and their electric organs later became important model tissues for studying acetylcholine receptors 鈥� protein channels that help nerves send signals to other cells.鈥�

The new findings build on this legacy, showing how electric fish can reveal principles related to sensing, stealth and decision making. Similar trade-offs shape sonar, radar and autonomous sensing technologies, suggesting that nature’s solutions to stealth and detection may offer insights for future adaptive sensing systems.

鈥淭his study shows that active sensing is not just about gathering information, but also about managing the risk of being detected,鈥� Crampton says. 鈥淭his opens opportunities for future research, from understanding how other aquatic species respond to electric signals to uncovering whether similar stealth strategies occur in other sensory systems.鈥�

This work was funded by National Science Foundation Graduate Research Fellowship Program grant 2035702 (L.P.), an American Philosophical Society Lewis and Clark Fund for Exploration and Field Research grant (L.P.), and National Science Foundation grant DEB-1146374 (W.G.R.C.).

Florida鈥檚 coastlines are changing, and so are the fish that depend on them.

As rising temperatures push tropical species northward and mangrove habitats expand into areas historically dominated by salt marshes, scientists are racing to understand how these shifts could affect marine food webs and long-term ecosystem stability.

Meredith Pratt, a 麻豆原创 integrative and conservation biology doctoral student, is helping answer those questions. Her research on sustainable fisheries management along Florida鈥檚 east coast earned her the prestigious Florida Sea Grant/Guy Harvey Fellowship. The highly competitive award supports graduate students conducting research that informs marine conservation and fisheries management while cultivating future leaders in marine science.

Tracking a Changing Ecosystem

Pratt studies how tropicalization 鈥� the northward movement of tropical species and habitats 鈥� is altering Florida鈥檚 coastal ecosystems.

“As temperatures rise, mangroves, traditionally found in warmer, tropical regions, are expanding northward into areas historically dominated by salt marshes,鈥� she says. 鈥淭his shift is influencing the species that live there.鈥�

To understand these changes, Pratt and her team study fish communities along Florida鈥檚 east coast. One fellowship-supported project focuses on predator-prey dynamics among popular sport fish, including common snook, red drum and spotted sea trout.

“The most interesting result so far is that the same fish species are eating different things, … and that raises important questions about how continued mangrove expansion could impact the ecosystem in the long term.鈥�

鈥淭丑别 most interesting result so far is that the same fish species are eating different things depending on whether they inhabit traditional salt marshes or increasingly dominant mangrove environments,鈥� Pratt says. 鈥淲hile most species primarily feed on shrimp, common snook tend to consume more fish, and that raises important questions about how continued mangrove expansion could impact the ecosystem in the long term.鈥�

These findings were supported through lab gut analysis of fish samples collected in the field using seine nets to determine stomach contents. Because digestion can make some prey difficult to identify, Pratt also used stable isotope analysis, which provides insight into a fish鈥檚position in the food web based on chemical signatures in its tissue.

鈥淕ut content analysis shows us exactly what a fish recently ate, while stable isotopes give us a longer-term picture of its diet,鈥� she says. 鈥淭ogether, they allow us to answer questions we couldn鈥檛 with just one method alone.鈥�

Guiding Future Fisheries Management

The research is both environmentally and economically important to Florida. As one of the world鈥檚 premier fishing destinations, the state depends on healthy coastal ecosystems and fish populations to support its recreational and commercial fisheries.

鈥淢any of the fish we rely on start in estuaries and coastal environments,鈥� Pratt says. 鈥淭丑别y grow in protected areas like mangroves and salt marshes before moving offshore. If we don鈥檛 understand how those habitats are changing, we can鈥檛 effectively manage the fisheries that depend on them.鈥�

Connecting Science and Community

Pratt is also expanding the impact of her research beyond the lab. Through her National Oceanic and Atmospheric Administration Margaret A. Davidson Graduate Fellowship, she launched the Guana Tolomato Matanzas (GTM) Fisheries Monitoring Program at the GTM National Estuarine Research Reserve.

“Getting people involved and helping them understand the importance of this work makes a big difference.”

The volunteer-driven initiative trains community members to collect fisheries data at designated sites, including species identification, abundance and size measurements. With nearly 20 volunteers participating, the program provides valuable long-term data while increasing public involvement in scientific research.

鈥淚t鈥檚 been one of the most rewarding parts of my Ph.D.,鈥� Pratt says. 鈥淕etting people involved and helping them understand the importance of this work makes a big difference.鈥�

A Full Circle Moment

For Pratt, earning the Florida Sea Grant/Guy Harvey Fellowship was a full-circle moment. As an undergraduate, she completed many of her classes and research experiences at the Guy Harvey Oceanographic Center at Nova Southeastern University. Now, funding from Florida Sea Grant and the Guy Harvey Foundation is helping advance her research while providing professional development opportunities in science communication.

鈥淭his fellowship not only supports my research but also allows me to connect with other scientists, stakeholders and the public,鈥� she says. 鈥淪haring our findings and contributing to science communication is a really meaningful part of the experience.鈥�

Looking ahead, Pratt hopes her work will support more informed decision-making around fisheries management and conservation.

鈥淐onservation requires research and education working together,鈥� she says. 鈥淚f we can understand what鈥檚 happening and communicate that effectively, we can make better decisions to protect these ecosystems for future generations.鈥�

A 麻豆原创聽 doctoral student has helped position 麻豆原创 as a contributor to the鈥疦orth American Bat Monitoring Program鈥�(NABat), a coordinated effort to track bat populations across North America using standardized acoustic methods.

鈥淢y Muscogee-Creek heritage has deeply influenced how I view the natural world, not as something separate from us, but as something we are accountable to,鈥� White says. 鈥淭hat worldview has guided my commitment to wildlife rescue and rehabilitation for more than a decade, and specifically to bat rehabilitation for the past seven years.鈥�

Florida is home to 13 resident bat species, including the Brazilian free-tailed bat and the southeastern myotis.

鈥淢y work is driven by a desire to ensure these often-misunderstood animals continue to thrive in increasingly human-dominated landscapes,鈥� White says.

Bringing NABat to 麻豆原创

As a board member of the鈥疐lorida Bat Working Group鈥痑nd the鈥疐lorida Bat Conservancy, White saw an opportunity to integrate applied conservation science with campus engagement. She approached the鈥疐lorida Fish and Wildlif Conservation Commission鈥痑nd leadership about adding the university to the NABat monitoring grid.

鈥淭丑别 North American Bat Monitoring Program provides a standardized framework for long-term bat population monitoring across the continent,鈥� White says. 鈥淏ecause there are known bat colonies on campus, participation was a natural fit.鈥�

Although 麻豆原创鈥檚 geographic grid cell is聽relatively small, its urban and suburban context fills important gaps in regional datasets.

鈥淯rban and suburban monitoring locations are underrepresented in many long-term datasets,鈥� White says. 鈥淭丑别 acoustic data collected on campus help fill knowledge gaps in Central Florida and the broader southeastern region.鈥�

The Science Behind Acoustic Monitoring

Before joining 麻豆原创, Nichols spent many years looking for new causes of diabetic neuropathy.

Now, a new study published in the American Ornithological Society鈥檚 Ornithological Applications journal details how researchers from 麻豆原创鈥檚 and colleagues analyzed the genetic variability, population structure and viable conservation strategies for Florida鈥檚 American flamingo.

鈥淎s a native Floridian who grew up in Tallahassee, Florida, I was fascinated and a little surprised to see the flamingo as a prominent state icon, yet I had never seen one in the wild,鈥� says Jessica Folsom 鈥�23MS, who led the study while earning her master鈥檚 degree in biology at 麻豆原创.

The Flamingo’s Lost History

Flamingos were nearly extirpated in Florida due to hunting and habitat loss. While later sightings suggested possible natural recolonization, many of the birds were thought to be escapees from zoos or other captive populations rather than signs of a true restoration.

Eric Hoffman, professor and chair of 麻豆原创鈥檚 Department of Biology and a co-author of the study, says the project revealed the depth of what was lost.

鈥淏efore this project, I wasn鈥檛 aware of the historical distribution or how common these birds were in Florida 100 to 150 years ago,鈥� Hoffman says.

An Unlikely Founding Population

Although flamingo populations remain large in regions near Florida, including The Bahamas, Cuba and Mexico, Florida’s first wave of birds originated in an unconventional setting.

鈥淚n the 1920s, the owner of a horse racetrack in Hialeah released roughly 20 flamingos, likely sourced from The Bahamas, as a marketing strategy to boost attendance and betting,鈥� Hoffman says. 鈥淭丑别 birds thrived in the wetland habitat at the track鈥檚 center, forming the founding population for many Florida zoo-held flocks, including Zoo Miami鈥檚.鈥�

Signs Florida Can Still Support Flamingos

In recent years, researchers say that flamingos generally fly into Florida from neighboring regions or arrive after hurricanes. Some flocks remain for months 鈥� evidence that Florida鈥檚 wetlands can support them 鈥� however, establishing a long-term breeding population remains a primary challenge.

鈥淭丑别se returning flocks have given us an opportunity to collect contemporary and historical samples to address questions about their genetics and population structure 鈥� a central focus of my lab,鈥� Hoffman says.

What the Genetics Reveal

Folsom, who conducted the research in Hoffman鈥檚 lab as a graduate student and now works as a biologist for the Florida Fish and Wildlife Conservation Commission, says populations that undergo extirpation or steep decline often face consequences such as reduced genetic variability, loss of unique local adaptations or alleles, and, in severe cases, a greater risk of inbreeding.

鈥淚n Florida, hunting for feathers could have created those conditions,鈥� Folsom says. 鈥淗owever, in our study, we found insignificant levels of inbreeding, little loss of genetic variability and minimal differentiation between Florida birds, the birds in Florida zoos, and other populations in the Caribbean and parts of South America.鈥�

The study included 188 flamingos spanning seven contemporary wild populations 鈥� from Cuba, The Bahamas, Bonaire, the Yucat谩n Peninsula, Mississippi, the Gal谩pagos Islands and Florida 鈥� as well as managed flocks, or ex-situ, housed in Zoo Miami and Hialeah Park. It also included five historical populations from Cuba, The Bahamas, Mexico, Florida and the Gal谩pagos Islands.

Because wild Florida specimens are limited, the team used other Caribbean wild populations as genetic proxies. Using whole genome sequencing across more than two million loci 鈥� the fixed positions of genes on a chromosome 鈥� the team analyzed data using bioinformatics software on 麻豆原创鈥檚 high-performance computing cluster, Stokes.

鈥淥ne of our most surprising findings was that modern flamingos showed significant genetic variability compared to historical populations,鈥� Folsom says. 鈥淐aptive populations showed the greatest genetic variability and minimal inbreeding, meaning they could be strong candidates for reintroduction. Genetic similarities also indicate flamingos from other regions could adapt well to Florida, with limited risk of outbreeding depression.鈥�

Researchers emphasize that reintroduction must be paired with policy change.

鈥淔or more than a century, there were almost no conservation measures for flamingos in the U.S.,鈥� says Steven Whitfield, director of Terrestrial and Wetlands Conservation at the Audubon Nature Institute and a co-author of the study. 鈥淭hat鈥檚 partly because flamingos were long considered a non-native species to Florida. With our work, we want to show they have always belonged here and there鈥檚 a scientific basis to support their recovery.鈥�

Why Policy Matters as Much as Habitat

A petition to classify the birds as threatened was filed with the state, Whitfield says, but the proposal did not advance, stating that flamingos don鈥檛 warrant inclusion on the threatened species list. Some officials have cited existing protections, such as Everglades National Park, as sufficient. Researchers disagree, saying habitat protections alone cannot ensure the species鈥� survival or population restoration.

鈥淭his study provides the evidence needed to prove that birds raised by zoos are a viable genetic match, opening the opportunity for reintroduction from zoo populations,鈥� Whitfield says.

Meanwhile, public momentum is strengthening legislative interest.

鈥淭丑别re is sustained statewide support for naming the flamingo Florida鈥檚 official state bird, and bills are now under review in both the Florida House and Senate,鈥� Folsom says. 鈥淭丑别y鈥檙e often the first image that comes to mind when you think of Florida, and that recognition drives ecotourism and public enthusiasm, which also supports broader wetland conservation efforts.鈥�

Successful recovery efforts in other regions point to promising intervention strategies.

鈥淎rtificial nest mounds can encourage breeding, and decoy flamingos have been used to signal an established flock, helping attract passing birds,鈥� Folsom says. 鈥淏oth tactics have shown success in human care and select wild settings.鈥�

A Path Forward for Restoration

While the long-term outlook for flamingos is good, the small numbers in Florida are not enough for the species to recover. Moreover, habitat destruction, pollution and warming temperatures add to the challenges they face.

鈥淣atural recovery of the flamingo is unlikely in Florida without intervention,鈥� Whitfield says. 鈥淏ut our study shifts that conversation. We can now confidently say ex-situ flamingos are genetically compatible with wild populations, which opens possibilities for a future release program, even though logistical hurdles remain.鈥�

For the researchers, the study has not only demonstrated how genetics can inform conservation but also provided an opportunity to raise awareness about an iconic species that has always been native to Florida.

鈥淕rowing up in Florida, it鈥檚 impossible not to appreciate its biodiversity,鈥� Folsom says. 鈥淲orking on this project with passionate colleagues like Eric and Steven has been incredibly rewarding, helping clarify the flamingos鈥� history in Florida and the value of protecting and reintroducing them.鈥�

While this sounds like the setting for a sci-fi novel, it鈥檚 actually the hometown of Assistant Professor Kirill Medvedev, a new faculty member in the . Medvedev grew up in Akademgorodok, which literally translates to 鈥淎cademic Town,鈥� a place that sparked his interest in bioinformatics and inspired his career.

鈥淭丑别 constant exposure to open, curiosity-driven inquiry made the language of science feel as natural as the Siberian forest around us,鈥� Medvedev says. 鈥淢y passion for bioinformatics and computational biology was ignited by a fascination with three-dimensional protein structures. I realized that computational approaches are indispensable for decoding life鈥檚 molecular machines, and it set me on the path toward research in the field of computational structural biology and bioinformatics.鈥�

Medvedev鈥檚 work focuses on the classification and analysis of large-scale biomedical data sets that span the molecular, cellular and tissue levels. With that expertise, he is teaching a Discrete Mathematics course at 麻豆原创 this fall. He says he hopes to instill both practical and technical knowledge in his students.

鈥淚 hope to share with my students not only the course knowledge but also my experience of being a scientist.”

鈥淚 believe that integrity is the defining characteristic of a scientist,鈥� he says.

Medvedev鈥檚 work focuses on the classification and analysis of large-scale biomedical data sets that span the molecular, cellular and tissue levels. Within the past decade, he developed the DrugDomain database, which lists the domain features of human proteins that are targets for small molecules and drugs. He augmented the DrugDomain database with artificial intelligence鈥憄owered protein structure prediction, creating a first鈥憃f鈥慽ts鈥慿ind resource that maps thousands of post鈥憈ranslational modifications to their drug targets across the human proteome. He also uses computational modeling to analyze variations within cancer types and employs deep learning methods to identify cancer subtypes.

The opportunity to collaborate with the next generation of scientists, as well as established colleagues, is what Medvedev says drew him to 麻豆原创.

“I was interested in the 麻豆原创 because it鈥檚 such a dynamic and fast-growing research hub 鈥� one that actively promotes collaboration among researchers.”

鈥淭oday, truly groundbreaking science cannot be done by one person, or even one lab, but only through collaboration among multidisciplinary teams,鈥� Medvedev says.

Medvedev earned his doctoral degree in mathematical biology and bioinformatics from the Institute of Cytology and Genetics in 2015. Following that, he鈥檚 worked with Professor Nick Grishin at the University of Texas Southwestern Medical Center as a postdoctoral researcher.

Doctoral students with strong computational skills who are interested in working with Medvedev can contact him by email. Basic understanding of molecular or structural biology or biochemistry is beneficial but not required.

Led by 麻豆原创 Professor of Biology and developed by undergraduate students, the new game blends research with interactive learning.

鈥淢y work on parasitic wasps and their symbiotic viruses forms the foundation for the game and other outreach efforts designed to engage the public with biology in a fun and accessible way,鈥� Sharanowski says.

The game was created by computer science senior students as part of their capstone project under the supervision of Associate Lecturer of Computer Science Matthew Gerber, with Sharanowski providing the concept. It represents the second phase of development, with an earlier senior group of students building the original concept and the second group advancing it into a fully playable desktop version.

鈥淭丑别 students coded, designed and refined the game, which was initially envisioned as a virtual reality experience but shifted to a desktop game 聽due to delays from the COVID-19 pandemic,鈥� Sharanowski says.

In the game, players take on the role of scientists tasked with protecting a national park by designing custom wasps to control invasive pests.

鈥淭丑别 goal as a scientist is to save the park by releasing specially designed wasps with beneficial features like paralytic venom, long ovipositors or even mind control, that make them more effective at targeting host species such as caterpillars, beetles and aphids,鈥� she says.

Along the way, players encounter educational blurbs that explain these traits and reinforce the idea that not all wasps sting and many are actually beneficial to humans and ecosystems.

鈥淭丑别se wasps can be endoparasitic, developing inside their host, or ectoparasitic, developing outside the host,鈥� Sharanowski says. 鈥淵ou can find them all around the world, including in our backyards, and they serve an important role in nature as natural agents of pest control, thereby reducing the need for pesticides.鈥�

The project was funded through the U.S. National Science Foundation鈥檚 (NSF) Rules of Life Initiative, which brings together multiple NSF divisions to address the fundamental questions about how living systems function and evolve.

According to Sharanowski, parasitic wasps are one of the most varied lineages on Earth, with more species than all vertebrates combined.

鈥淔or every insect that鈥檚 out there, there鈥檚 likely one or more parasitic wasps that attack it,鈥� she says.

Her research explores the unique symbiosis between wasps and viruses.

鈥淥ver time, some viruses have become integrated into the genomes of certain parasitic wasps, effectively making the virus and wasp a single organism,鈥� Sharanowski says. 鈥淭丑别 virus no longer replicates independently 鈥� its reproduction is tied to the wasp鈥檚. When a female wasp lays an egg inside a host, the virions enter the host and activate viral genes that manipulate the host鈥檚 immune system and behavior, benefiting the developing wasp.鈥�

This wasp-virus relationship has evolved multiple times and remains a central focus of her research.

As a first-generation college graduate, Sharanowski says this project has been a way to share her passion for entomology and science, as well as to provide educational opportunities for people to learn about wasps in a fun way.

鈥淥ne of my core values as an educator is to make science engaging,鈥� she says. 鈥淚 enjoy doing campus and community outreach to show how fascinating these insects are, and I believe this game does that.鈥�

She also highlighted 麻豆原创鈥檚 Collection of Arthropods, commonly known as the , as a public resource preserving and showcasing the biodiversity of insects in Central Florida.

Looking ahead, Sharanowski says a third group of students is currently working on a mobile version of the game, expected to launch later this year.

鈥淭丑别re is so much beauty out there, and I want people to see how fascinating bugs are and the important role they play in ecosystems,鈥� she says.

These findings challenge existing hypotheses and provide important data for assessing risks from human activity and informing conservation efforts.

The study, funded largely in part by Florida RESTORE Act Centers of Excellence Program, was published this week in the journal Proceedings of the Royal Society B, representing the largest satellite tracking dataset of wild-caught juvenile sea turtle behavior from the Gulf of Mexico during this life stage, spanning from 2011 to 2022.

鈥淥ne of the main findings is where these sea turtles are and where they go in this life stage because we haven鈥檛 known much about it,鈥� says 鈥�22笔丑顿, who led the study alongside Nathan Putman and . Phillips says understanding these movement patterns among juvenile sea turtles will help guide conservation efforts to protect critical habitats for these species.

After hatching, sea turtles are known to leave their nests on land and enter the ocean where they spend their early years. This shift from terrestrial to oceanic habitat marks a critical transition in their life cycle to a life stage that has been understudied.

According to Mansfield, co-author of the study, professor of biology at 麻豆原创, and director of the 麻豆原创 Marine Turtle Research Group, we are still learning about this life stage and it鈥檚 more complex than assumed.

鈥淲e don’t know what they’re eating, about their health, if and when they associate with floating algae called sargassum, which provides some protection,鈥� Mansfield says.

The team of researchers tagged 131 juvenile sea turtles 鈥� 94 green turtles, 28 Kemp鈥檚 ridleys, five loggerheads, and four hawksbills 鈥� and tracked their movements using satellite-equipped, solar-powered platform transmitter terminals. These movements were compared with those of oceanographic surface drifters, floating objects used to study how sea turtle movements are influenced by ocean currents.

Researchers believe juvenile sea turtles swim offshore as an adaptive behavior to avoid predators such as birds, sharks and other fish, which are more abundant near the shoreline. Their small size makes them particularly vulnerable, so offshore waters can provide a safer refuge.

鈥淥ne of the longstanding assumptions, is that juvenile sea turtles stay far offshore. Researchers call this the 鈥榦ceanic life stage,鈥� which means off the continental shelf in waters deeper than 200 meters,鈥� Phillips says. 鈥淗owever, what we found was that the turtles in this life stage are crossing over the continental shelf into neritic zones a lot more than we expected.鈥�

A continental shelf is the gently sloping, shallow underwater area that extends between the shoreline and the continental slope, where the seabed drops steeply into the deep ocean at the shelf break. This shelf includes the neritic zone, which is the part of the ocean closest to the coast, characterized by nutrient-rich waters and a high concentration of marine life.

Phillips says the sea turtles were found crossing over to shallower waters and closer to shore, but it did not appear that they were transitioning to their next life stage, where they typically move to shallow habitats and feed off the bottom. Instead, the turtles seemed to approach the shore, then turned to avoid it.

鈥淭hat was interesting because we had these passive drifters that we released with them and many of them washed up shore and none of the turtles did,鈥� Phillips says.

She adds that if the turtles don’t behave like passive particles drifting with the currents and can actively swim and control their position, then existing movement models could consider both factors to correct errors in projections.

Existing hypotheses about the early life stage of most sea turtle species suggested they live exclusively in oceanic environments, drift passively with ocean currents and typically do not return to their previous habitat once they transitioned to a new one. However, these assumptions lack research into actual movement behavior.

鈥淗istorically, all our information about this young life stage has been limited to opportunistic sightings of these little, hard-to-see animals from boats passing by, tracking work on hatchlings in the first 24 hours after leaving nesting beaches, or laboratory studies,鈥� Mansfield says.

Previous work also focused on the North Atlantic and on loggerheads, a species that commonly nested on the east coast of the U.S.

鈥淚 think it鈥檚 important to get data from different places and put the puzzle together to get a bigger picture of what鈥檚 going on,鈥� Phillips says. 鈥淩esearchers tracking this species were finding that they were staying offshore. But now that turtles are tracked from more places, we are finding that there are more nuances to what goes on. Loggerheads, for instance, we found stay off the continental shelf located in the west coast of Florida.鈥�

Mansfield says sea turtle tracking can be costly, labor intensive, and the technology has limitations.

鈥淚t鈥檚 really hard to follow and manually track a little turtle over time,鈥� Mansfield says. 鈥淵ou have to fuel a boat with researchers who have a strong stomach to go into the ocean. Historically, technology just wasn鈥檛 there to put a tag on a turtle and use satellites to be able to remotely track where they went. Tags were battery powered and as big as a brick.鈥�

Prior to her time at 麻豆原创, Mansfield figured out a method to safely tag and effectively track small turtles, thanks to more reliable tagging technology, which played a role in conducting this study and achieving its results. She also credits their partnership with Inwater Research Group in helping to catch and track smaller sea turtles.

This research into sea turtle movement during the 鈥渓ost years,鈥� provides data for conservationists to assess and manage risks from human activity.

鈥淭丑别 Deepwater Horizon oil spill in 2010 was a bit of the origin story of this project,鈥� Mansfield says. “If we have another oil spill, we need to know whether these animals [will be] transient through an area, stuck there due to currents, or if they鈥檒l end up somewhere else.鈥�

Data from this study is already driving conservation efforts, including a proposal for critical habitat designation under the Endangered Species Act for green sea turtles. This designation would complement earlier tracking data led by Mansfield, which established critical habitat for loggerheads 鈥� the sargassum algae nursery.

Mansfield and Phillips say if assumptions are that these animals are strictly oceanic, then they may not be protecting them completely or addressing what they need for their eventual recovery.

鈥淚f sea turtles are occurring on the continental shelf, we suggest renaming this life stage to 鈥榙ispersal stage鈥� to account for their behavior,鈥� Mansfield says. 鈥淭his is important nuance in their life history, and the new terminology reflects a better understanding of sea turtle behavior, revealing more about these lost years.鈥�

The Aylesworth Scholarship was established in 1984 through a joint partnership between the Aylesworth Foundation for the Advancement of Marine Science, the鈥疭outheastern Fisheries Association鈥痑nd the Florida Sea Grant College Program. Aylesworth scholarships are named annually, with a few students selected among undergraduate and graduate student applicants across all Florida universities that conduct research in the marine sciences. Aylesworth Scholarship recipients study many subjects that impact the fishing, seafood and marine industries.

Banquero鈥檚 pathway to pursue marine science began in childhood.

鈥淪cience and biology were always my best subjects in school and my family encouraged my curiosity about plants and animals,鈥� Banquero says. 鈥淟ater, I felt drawn to conduct research that would contribute to protection of the places I鈥檇 enjoyed as a child and had the opportunity to explore in my biology studies at 麻豆原创.鈥�

In Fall 2019 during her studies at 麻豆原创, she began to participate in field work, data entry, and other support for , or CEELAB.

鈥淚 literally and figuratively got my feet wet,鈥� Banquero says.

CEELAB provides opportunities for 麻豆原创 students studying biology in the College of Sciences to work in the field, building hands-on experience. This summer, 15 麻豆原创 students are working on coastal restoration and monitoring in the Indian River Lagoon, as well as conservation projects focused on microplastics or coastal acidification.

Pegasus Professor Linda Walters聽runs the CEELAB, working alongside the students and supporting independent research projects, matching their interests with the needs of the local ecosystem.

鈥淚t becomes real at 6:30 a.m. when students are moving biodegradable restoration materials to damaged, intertidal oyster reefs while standing in mud in the middle of a hot, Florida summer,” Walters says. “This is how coastal restoration happens and where students put their passion for marine biology to work.鈥�

Banquero鈥檚 experience through CEELAB was profound, providing her with opportunities to see nature and wildlife 鈥� including sea turtles and manatees 鈥� firsthand, as well as observe the human impacts on coastal environments.

Her work in CEELAB stood out to Walters, who continues to see promise in Banquero鈥檚 thesis work toward her master’s in biology at 麻豆原创.

鈥淪he is a determined person and has wonderful insight and tenacity that will serve her well as a scientist,鈥� Walters says. 鈥淟uciana is a very worthy recipient of the Aylesworth Scholarship and has a bright future in marine science.鈥�

鈥淭丑别 experience I have had as a student at the College of Sciences has been lifechanging,” Banquero says . 鈥淚鈥檓 doing things that have surprised me and found a path forward. I鈥檓 grateful to the biology department for helping to open doors for me in the field of conservation.鈥�

As a first-generation college student, Banquero hopes to inspire more students to pursue careers in marine science and for the public to become more engaged in ecosystem restoration efforts.

鈥淚 hope more people pay greater attention to the value of coastal marine resources and see the value in conserving, restoring and protecting them,鈥� Banquero says.
