Students and Postdoctoral Associates

The ACCSTR has a very active graduate student program with students from a number of departments at the University of Florida. The involvement of graduate students in our research ensures that, while answering critical questions in sea turtle biology, we are also educating future sea turtle biologists and conservationists.

Examples of the type of research conducted by ACCSTR graduate students can be seen in the following link: Theses and Dissertations of the ACCSTR

Graduate Students

Ariadna Arnau

Email: ariadna.arnau@ufl.edu
Department: Biology
Major Professor: Karen A. Bjorndal & Hannah Vander Zanden

Ariadna is a marine biologist interested in ecology, behavior and conservation of sea turtles. As a passionate field biologist, she has worked for nonprofit organizations since 2009, contributing to the conservation of sea turtles over multiple nesting seasons in Cape Verde, Costa Rica, Ghana and U.S. Ariadna’s research interests include understanding the extrinsic and intrinsic factors that influence sea turtle’s breeding strategies (capital or income) by using stable isotopes as well as their reproductive energy budgets.


Nerine Constant

Email: nconstant@ufl.edu
Department: Biology
Major Professor: Karen A. Bjorndal

Nerine’s research focuses on the effects of green turtle grazing on ecologically and economically important fish communities in Caribbean seagrass meadows. Understanding how green turtles impact the structure and function of seagrass ecosystems is critical to ecosystem-based fishery management. Nerine’s research incorporates her broader interests, which include studying the roles of sea turtles in marine ecosystems and contributing to conservation efforts and sustainable management of coastal resources.


Rogério Ferreira

Email: coriacea@gmail.com
Faculty of Science and Technology
University of Algarve, Portugal

Rogerio’s research is centered at Principe Island, a recent UNESCO Biodiversity Reserve in West Africa. By using several methodologies (nesting and in-water census, telemetry and isotopic and genetic analyses), in collaboration with other researchers, he aims to gain understanding on the distribution and abundance of the sea turtle populations in this region, including their connectivity with other foraging and breeding areas. As an overall goal, Rogerio hopes to contribute to the conservation of sea turtles in the region.


George GlenGeorge Glen

Email: george.glen@ufl.edu
Department: Biology
Major Professor: Karen A. Bjorndal

George is interested in the reproductive biology and foraging ecology of sea turtles, particularly the intersection between the two. For example, how will ecological change on foraging grounds affect migrations, age at maturity, and fitness. Currently, George is looking at the possible role of biological senescence in green turtles with the aim of improving population models to better inform management decisions.


Richard M. Herren

Email: rherren@ufl.edu
Department: Wildlife Ecology and Conservation
Major Professor: Ray Carthy

Rick’s research is focused on spatial distribution and habitat selection by juvenile sea turtles in Florida’s nearshore waters. In particular, he is interested in determining the biotic and abiotic factors driving turtle aggregations using predictive models. Other interests include examining temporal and spatial changes in juvenile sea turtle movements, diet, growth and disease in response to climate change.


Ashley Meade Kusel

Email: ashleymeade@ufl.edu
Department: Biology
Major Professor: Karen A. Bjorndal

Ashley is interested in green turtle and seagrass ecology, specifically if seagrasses have anti-herbivory responses to green turtle grazing and how those responses may affect green turtles. She also has special interests in habitat conservation. Ashley will quantify the presence of herbicide runoff (glyphosate) in Florida seagrass meadows while developing a new seagrass rapid assessment method that accounts for grazing.


Christopher Nolte

Email: c.nolte@ufl.edu
Department: Biology
Major Professor: Hannah Vander Zanden

Chris’s research focuses on leatherback sea turtles in the southwest Indian Ocean to better understand why this population is critically endangered, despite six decades of protection. His main goal is to determine if the areas established for conservation are appropriate based on genetic structure, health, and distribution of the leatherback population.


Marco SantosMarco Santos

Email: msantos@uac.pt
University of the Azores, Portugal

 

Marco is studying the movements and distribution patterns of oceanic juvenile loggerheads in the waters around the Azores. Marco is using satellite telemetry and remote sensing technologies.


Renato Saragoca Bruno

Email: rsaragocabruno@ufl.edu
Department: Biology
Major Professor: Karen A. Bjorndal

Renato’s research tackles the reproductive dynamics of green turtles (Chelonia mydas) foraging in the Caribbean off Nicaragua and nesting at Tortuguero, Costa Rica, using the visual inspection of gonads. Caribbean green turtle populations had decreased by more than 97% since pre-Columbian times before increasing somewhat in recent decades. Better understanding of factors influencing green turtle reproductive output is crucial for devising conservation strategies to mitigate the accruing threats sea turtles face on a rapidly changing planet.


J. Rachel Smith

Email: jrachel.smith@ufl.edu
Department: School of Natural Resources & Environment
Major Professor: Raymond R. Carthy

Rachel is interested in improving the sustainability of fisheries through testing of bycatch reduction technology (BRT), while also studying adoptability of proposed BRT innovations in commercial fishery systems. Rachel is passionate about taking an evidence-based approach to solving complex conservation challenges, and after working primarily on sea turtle nesting beaches, is excited about this foray into fisheries conservation research.


Postdoctoral Associates

Bethan Linscott

Email: bethan.linscott@ufl.edu
Department: Biology
Postdoctoral Supervisor: Hannah Vander Zanden

Bethan’s research focuses on the application of isotopic techniques to reconstruct prehistoric animal and human mobility and subsistence. Before joining UF, Bethan specialized in compound specific radiocarbon dating and sequential strontium isotope analysis of the tooth enamel of Neanderthals, anatomically modern humans, and terrestrial fauna using high-resolution laser ablation MC-ICP-MS. She is excited to be joining the world of modern ecology to work on the application of isotopic methods to age and reconstruct ecological histories of sea turtles.


Undergraduate Students

Jenna Bennett

Email: jennabennett@ufl.edu
Department: Biology
Supervisor: Hannah Vander Zanden

Jenna is researching new methods to age sea turtles. Her project  is aimed at validating age estimates with eye lenses of deceased sea turtle hatchlings.
