Danielle BartzDanielle is a doctoral student in the Marine Biology Graduate Program at the University of Hawai'i-Manoa. She is examining spatial and temporal changes in the use of Hilo Bay by juvenile Scalloped Hammerhead Sphyrna lewini and reconstructing the distribution and approximate fishing effort through the use of local traditional ecological knowledge.

Kaikea NakachiKaikea is a M.S. student in the TCBES Graduate Program at the University of Hawai'i-Hilo. He is developing a photo identification protocols for Tiger Shark Galeocerdo cuvier in order to complete a population estimate for west Hawai'i Island using non-invasive sight-resight methods. Kaikea's research and shark conservation efforts were recently featured in a Honolulu Civil Beat article. Kaikea is co-advised by Dr. Jason Turner with the Marine Science Department at the University of Hawai'i-Hilo Click HERE to email Kaikea |

Nikola RodriguezNikola is a M.S. student in the TCBES Graduate Program at the University of Hawai'i-Hilo. She is assessing the effects of coral cover loss and management strategy on the probability of occurrence of ciguatoxins in Peacock Gouper (Roi) Cephalopholis argus and Goldring Bristletooth (Kole) Ctenochaetus strigosus along the west coast of Hawai'i Island.

Matthew Acre, Ph.D.Matt received his M.S. from Texas Tech University in 2015 and completed his Ph.D. in 2019. His THESIS compared larval fish assemblages from backwaters in the river-reservoir interface (RRI) zone of Lake Livingston in east Texas to those in natural, floodplain habitats of the Trinity River. He showed that larval fish abundances were higher in RRI backwaters, but riverine species dependent upon natural floodplain habitats were not using them as surrogate habitat. His DISSERTATION examined the demographics and behavior of Blue Sucker in the lower Colorado River in central Texas as shown in this Texas Parks and Wildlife-produced VIDEO. He is currently research fish biologist with the U.S. Geological Survey at the Columbia Environmental Research Center. FOLLOW Matt on ResearchGate |

Preston Bean, Ph.D.Preston was a postdoctoral research associate in the Grabowski Lab during 2012-2014. His RESEARCH focused on developing baseline demographic data for Guadalupe Bass Micropterus treculii in an undisturbed population to inform conservation and management decisions throughout the range of the species. Preston currently is a watershed biologist with Texas Parks and Wildlife Department. |

Qingman 'Abby' ChenQingman received her M.S. from Texas Tech University in 2014. Her THESIS investigated the role of sound production in the mating system of Spotted Seatrout Cynoscion nebulosus. She found that acoustic activity was highly correlated to the probability of gamete release and that calls served specific functions in the mating system of Spotted Seatrout.

Jessica EastJessica was a research associate with the Grabowski Lab during 2015-2016. She developed rapid fish and habitat surveys to evaluate active and potential lease sites in support of Texas Parks and Wildlife's River Access and Conservation Areas program. Jessica is currently a biologist with the Kentucky Department of Fish and Wildlife Resources |

Jillian Groeschel-TaylorJillian received her M.S. from Texas Tech University in 2013. Her THESIS explored the age-specific habitat use and habitat-specific growth rates of Guadalupe Bass Micropterus treculii. Her results showed that growth of young-of-year Guadalupe Bass were sensitive to low flow conditions, likely due to their preference for riffle habitats. FOLLOW Jillian on ResearchGate |

Wade MassureWade received his M.S. from Texas Tech University in 2016. His THESIS evaluated the relative influence of drought and flow alteration on the growth of fishes living in two adjacent streams in the Llano River watershed in central Texas. While responses were species-specific, the response to drought tended to be more exaggerated in fishes living in the less impacted of the two streams. Wade is currently a biologist with the Kentucky Department of Fish and Wildlife Resources FOLLOW Wade on ResearchGate |

Seiji Miyazono, Ph.D.Seiji was a postdoctoral research associate with the Grabowski Lab during 2015-2016, though he is still closely collaborating with Dr. Grabowski. Seiji is conducting research to evaluate the influence of stream discharge on young-of-year Rio Grande Blue Sucker Cycleptus sp. cf. elongatus occupancy in the Big Bend region of the Rio Grande. He is also examining the influence of flow regime on growth and year-class strength of blue suckers in the Rio Grande and Sabine River. |

Julia MuellerJulia received her M.S. from Texas Tech University in 2013. Her THESIS examined the effects of temperature, dissolved solids, and suspended solids on the developmental rate and buoyancy of the embryos of Arkansas River Shiner Notropis girardi. Her work indicated that developmental rate tended to be positively correlated to temperature and suspended solids but at the cost of lowered survival. Julia is a fish biologist with the National Park Service at the Lake Meade National Recreation Area |

Jessica Pease, Ph.D.Jessica received her Ph.D. from Texas Tech University in 2018. Her DISSERTATION focused on the effects of changing flow regimes and land-use patterns on Guadalupe Bass Micropterus treculii populations throughout the Colorado River Basin in central Texas. She is currently a biologist with the Washington Department of Fish and Wildlife. FOLLOW Jessica on ResearchGate |

Elizabeth RoeslerBeth received her M.S. from Texas Tech University in 2016. Her THESIS focused on the factors determining the habitat use and detectability of an endangered spring snail, Pecos assiminea Assiminea pecos at Bitter Lake National Wildlife Refuge in New Mexico. Her work suggested that attempts to restore habitat for this snail by removing invasive plants, such as common reed, may be counterproductive unless the plant litter is removed as well. Beth is currently a doctoral student at Texas Tech University. FOLLOW Beth on ResearchGate |

Ricky TabanderaRicky received his M.S. from the University of Hawai'i at Hilo in 2019. His THESIS focused on the evaluating functional equivalency as fish nursery habitat of abandoned and restored Hawaiian fishponds to natural estuaries. Ricky is currently a biologist with NOAA Fisheries at the Northeast Fisheries Science Center. |
