Rolando O. Santos Corujo, Ph.D., Postdoctoral fellow

rsantosc@fiu.edu

Research Topic: I am a postdoctoral fellow at FIU under Dr. Rehage’s guidance and a marine spatial ecologist. My research focuses on the restoration and resilience of marine habitats and faunal responses to multi-scale habitat characteristics. Research interests center on the application of landscape ecology concepts in marine ecosystems to study the influence of spatial structure and habitat heterogeneity on the patterning of marine communities, and species interactions, distribution and movement. My current work uses a combination of modelling and quantitative methods that integrate multiple catch and environmental datasets to identify the underlying drivers of bonefish dynamics in Florida Bay.

About Me: I was raised in Puerto Rico and graduated from the University of Puerto Rico Rio Piedras Campus with a dual BSc degree in environmental science and geography in 2004. I moved to South Florida in 2006 for my graduate studies. In 2010 I received a dual MSc degree in marine biology and coastal management from Nova Southeastern University, and in 2014 I received my PhD in marine biology and fisheries from the University of Miami Rosenstiel School of Marine and Atmospheric Science.

Ryan Rezek, Ph.D Postdoctoral fellow

rrezek@fiu.edu

Research Topic:  I am currently researching the influence of seasonal variations in freshwater inflow and productivity on food webs across the Marsh-Estuarine-Marine gradient in the Florida Coastal Everglades. Our goal is to use stable isotopes and other food web analysis techniques to study habitats along the Long Term Ecological Research Network (LTER) to characterize the effect these environmental variations have on the pathways of energy flow across the system. Obtaining this information is critical to understand and predict the functional response of the system to major drivers of environmental change, including sea level rise and hydrological modifications associated with the Comprehensive Everglades Restoration Plan.

About Me: My hometown is Ashland, Oregon. I received a BS in Ecology and Evolutionary Biology at UC Santa Cruz, my Masters in Marine Biodiversity and Conservation from Scripps Institute of Oceanography (UCSD), and my Ph.D. in Coastal and Marine System Science from Texas A&M University-Corpus Christi. My research interests broadly include food web and restoration ecology. My work experience includes teaching, environmental consulting, and government positions.

Carissa Gervasi, Ph.D. Student

cgerv002@fiu.edu

Research Topic: Fisheries management

About Me: I received my BS degrees in Marine Biology and Chemistry from Roger Williams University in 2011, where I studied ecology of juvenile flatfish and bluefish toxicology. I then went on to pursue my MS degree in Marine Science at the Virginia Institute of Marine Science, focusing on fisheries population dynamics and pathobiology in the Chesapeake Bay. After working as a histotechnologist for a few years I decided to come back to school and started a PhD program at FIU in the Earth and Environment department in 2016. For my dissertation I am working closely with recreational anglers and state managers to develop a management plan for the Jack Crevalle, a valuable pelagic fish species whose population may be in decline.

Jordan A. Massie, Ph.D. Student

jmassie@fiu.edu

Research Topic: My primary research interests include aquatic community and population dynamics, along with understanding how biotic and physical habitat variables interact to influence the distribution of fishes over time and space. At FIU my research will focus on fish communities in the Florida coastal Everglades in order to better understand changing conditions and help inform ongoing restoration efforts.

About Me: My formative years were spent in the Upper Peninsula of Michigan, but I moved west as a young man and spent a number of years in Oregon. After a prosperous career in the bicycle industry, I returned to school at Oregon State University where I received my BSc in Fisheries & Wildlife Science. I have worked extensively in the remote wilderness as both a terrestrial and aquatic biologist on projects ranging from using radio telemetry to characterize the movement of Bighorn Sheep to studying the long term influence of timber harvest on fish and amphibians in headwater streams. Before coming to FIU, I worked as an aquatic ecologist in a federal research laboratory as part of a team developing new models to characterize the distribution of fish assemblages under current and future scenarios in order to help communities and governments guide restoration and conservation efforts. In recent years I have also been active in field based educational outreach programs teaching elementary school students about riverine fish ecology.

Jonathan Rodemann, Ph.D. Student

Jrode010@fiu.edu

Research Topic: How biotic and abiotic factors affect fish movement and behavior. During my time at FIU, I am focusing on how habitat transformation caused by a seagrass die-off in Florida Bay has affected the movement and trophic ecology of recreational sportfish.

About me: Growing up in New Jersey, I developed a love for ocean creatures from a young age. After high school, my interest in marine life brought me to south Florida, where I obtained a B.S. in Marine Science and Biology from the University of Miami. I attended a non-thesis based Master’s program at Northeastern University called the Three Seas Program, where I spent time in Boston, Panama, and Washington state learning about the marine ecosystems of these regions. This program ended with an internship with the Smithsonian’s Tennenbaum Marine Observatories Network looking at the variation in marine consumption pressure along a latitudinal gradient. I was then drawn back down to south Florida, where I started a PhD at FIU in the Coastal Fisheries Lab.

Nicholas Castillo, Ph.D. Student

ncast169@fiu.edu

Research Topic: The potential impacts of contaminants on the bonefish decline in South Florida. By comparing bonefish sampled throughout South Florida with bonefish from other Caribbean basins including the Bahamas, Puerto Rico, Mexico, and Belize I plan to identify present levels of contaminants and assess the relative risk in South Florida compared to the rest of the Caribbean.

About Me: I studied at the Nicholas School of the Environment at Duke University. Following graduation, I worked as a backcountry and inshore fishing guide out of Islamorada in the Florida Keys. I apply my lifelong love of fishing and Florida’s marine ecosystems with my experience within Florida Bay and the Florida Keys as a fishing guide to my current PhD research. I have travelled to Puerto Rico to collect bonefish samples, and am currently sampling the Florida Keys and Biscayne Bay. I greatly look forward to completing my research and PhD with the Rehage Lab!
