Emma Stierhoff



Graduated 2024



I am from Westfield, New Jersey. I graduated from Lafayette College in Pennsylvania in 2020 with a B.S. in Biology and a minor in Environmental Studies. While there, I carried out several studies on songbird behavior and physiology, through which I discovered my love for wildlife research. After graduating, I worked in a COVID-19 testing lab for a year, but eventually got to re-enter the conservation world implementing a marsh bird study under the Florida Fish and Wildlife Conservation Commission for a field season. I joined the LOHE Lab in 2021, and am conducting research on the behavioral and physiological effects of chronic avian malaria on Hawai'i 'amakihi. I am collaborating with folks from USGS and the National Park Service to conduct this study at Ainahou Ranch in Hawai 'i Volcanoes National Park where 'amakihi persist despite the extremely high malarial infection rate (~50%). We are hoping to learn more about what allows them to survive despite such a high disease rate and the long-term impacts of this disease on individuals in the poulation

Dan Mikros



Graduated 2023



Aloha! I'm Dan ‘Dio’ Mikros. I grew up on the Southside of Chicago without much more than steel and concrete around me. After discovering the natural world late in life, I became so fascinated chasing all manner of creatures around that I pursued a bachelor’s degree in integrative biology from the University of Illinois. Since then, I have worked in 12 states across the country on a wide variety of projects. But I have primarily focused on the ecology of arthropod-borne pathogens, including West Nile virus, dengue fever and Lyme disease. In 2018 I was lucky enough to bring my skills in this field to the Big Island where I started work with the HCSU researching the role ambrosia beetles play in vectoring rapid ohi’a death. I feel truly grateful to be able to continue developing this research within the TCBES program and alongside the LOHE lab. Here I hope to investigate how ambrosia beetles affect the spatial distribution of Ceratocystis inoculum in the environment, develop more effective ambrosia beetle management strategies, and monitor the potential threat of Ceratocystis to other endemic Hawaiian tree species.

Noah Hunt



Graduated 2023



Like a vagrant bird caught in a storm, I didn’t choose to work in Hawai’i, rather, it chose me. Like many animal enthusiasts, I pursued a pre-veterinary track in college until I discovered that I was happiest in wild spaces, like those near my hometown of Spokane, Washington, and wanted to protect them. After graduating from Cornell University in 2015, with my B.S. in Biology, I returned near home to study deer responses to forestry treatments in Colville National Forest. After applying far and wide for my next job, I seemingly randomly found myself on O’ahu, studying seed dispersal by introduced birds and rodents. I fell in love with Hawai’i’s diverse ecosystems, birds, and people, and after learning about the dramatic history of resource exploitation, invasive species introduction, and mass extinction of birds and plants, I endeavored to get involved with managing invasive predators. I worked in Hawai’i Volcanoes National Park for 9 months studying benefits of invasive rat removal for ‘Elepaio nesting. Other exciting opportunities drew me to work with fairy-wrens in Australia, Canada jays in Denali National Park, and migratory songbirds on the Colorado River, but my heart kept drawing me back to Hawai’i, including in 2019 when I worked with the Kaua’i Forest Bird Recovery Project on the critically endangered ‘Akikiki, ‘Akeke’e, and Puaiohi. My experiences have influenced my choice in master’s project, which is funded by a joint Department of Defense grant with my alma mater, Cornell University. I am interested in applications of passive acoustic monitoring as a tool for estimating bird population density and answering questions about avian ecology, while creating minimal disturbance and drawing less time and resources away from other management tasks. I am excited to be working in a tight-knit community with so much passion and talent, and grateful that the trade winds blew me back this way.

Paulo Ditzel



Graduated 2023



Hi, I'm Paulo, and I've come a long way following birds. I'm from Brazil, but I did my undergraduate and graduate studies in Berlin, Germany. Now I've flown here from literally halfway across the world to do my Thesis research on a topic I’m very passionate about. I've done quite a bit of bird-related work over the years, from the icy shores of the North Sea to the Atlantic Rainforest, but I keep getting drawn back to islands. Something about the unique evolutionary processes happening in these special places never ceases to amaze me. For my thesis I'm recording 'apapane songs, to analyze their huge repertoire size, song structure and local dialects in order to get an insight into their vocal learning process.

Andre Vannguyen



Fall 2019 Cohort



Aloha! I am a first-generation, Vietnamese-American college student. During my first semester of college, I decided to go against my parents' wishes and switch my major from Marketing to Animal Behavior. Fast forward some years and I have traveled to Wyoming x2, Panama, and Louisiana for avian research. I am incredibly fortunate for these experiences because they opened my eyes to the world of avian conservation and ecology. And where else would I go to continue following this dream of mine other than Hawaiʻi? My current research will determine the feasibility in using AudioMoths (low-cost, customizable acoustic device) and vocal activity rate for population density estimates of the iconic ‘i‘iwi. In addition, we want to look at potential abiotic impacts on vocal activity rates, and consequently examine how these components may influence density estimations. We hope to refine this particular methodology so that it can be applied to avian monitoring efforts across the Hawaiian Islands and beyond

Stephanie Mladinich



Graduated 2023



Aloha, my name is Stephanie Mladinich and I am from Albuquerque, New Mexico. I graduated from the University of New Mexico in 2015 with a dual degree in Biology and Latin American Studies, and have since worked in Mozambique, Panama and Brazil focused on forest and watershed ecology, restoration of degraded lands, and community-led conservation. It is an honor to work alongside so many passionate and inspiring individuals within the LOHE lab, UH Hilo and the greater Hawai'i community, and I am expanding my scope every day as I continue to learn from my peers and mentors. My current research is supported by the Pacific Island Climate Adaptation Science Center (PICASC) and is focused on mosquito surveillance in the mid to high elevation forests of Hawai'i Island, and the ecological drivers of mosquito distribution and abundance across the landscape. By increasing our understanding of this dynamic system, we hope to inform an early warning system of mosquito invasion at high elevations to implement actions that can safeguard Native Hawaiian forest birds from disease transmission.

Trisha Alvarez



Graduated 2022



Aloha, my name is Petrisha Alvarez. I grew up on Molokai, always exploring the environment around me from Mauka to Makai. Observing the diverse species of Hawaiʻi sparked my interest to further my education within the field of science. I obtained a bachelors in Microbiology from the University of Hawai`i at Mānoa and gained some research experience at the Center for Microbial Oceanography; Research and Experience (C-MORE) Hale. After graduating, I joined Kupu’s Hawaiʻi Youth Conservation Corps to understand better processes of conserving Hawaii’s diverse ecosystems. My experience with Kupu amplified my reasoning for studying higher education in Tropical Conservation Biology, as there are so many unanswered questions of how to save these native species from extinction. I was a part of many beach clean-ups which opened my eyes to the broader impact nets and plastics have on our native ecosystems. During the 2018 winter season, I found a juvenile humpback whale entangled in a fishing net with two buoys tightly wrapped around its left peck. It saddens me to see the young whale in distress, approaching my family’s boat many times as if asking for help to be set free. We stayed with the whale for hours until assistance from NOAA arrived. I hope to use all my knowledge and experiences to make an impact to protect these native species. My research at LOHE will consist of better understanding the habitat distribution of Hawaiian Spinner Dolphins along the East Coast of Hawai`i Island. Hawaiian Spinner Dolphins are frequently sighted along the Leeward coast of Kona, where human disturbances threaten their rest. Not many studies have ventured to the Windward Coastlines where weather conditions are harsher for marine research. I will be using various hydrophones to map out locations where Hawaiian spinner dolphins are present along the East Coast of Hawai`i Island, such as Hilo Bay.

Amanda Navine



Graduated 2022



Growing up in rural Wisconsin I always had a deep connection to nature and wanted to participate in conservation. While working toward my B.S. in Biology at the University of Wisconsin-Madison I enrolled in 'Birds of Southern Wisconsin. This class taught me all the birds of Wisconsin, by sight and sound, and I was impassioned to direct my efforts into avian conservation biology. After my graduation from UW in 2016 I participated in the Wisconsin Society for Ornithology Noel Cutright Breeding Bird Internship. The aim of this program was to expand our knowledge on the reproductive trends of native and non-native bird species. I also worked in a virology lab on the UW campus during this time. I built up and honed my research skills by using biochemical assays and super-resolution fluorescence microscopy to refine our understanding of self-interactions formed by a RNA virus protein. Currently, I am working in the LOHE lab to understand the effects of Rapid `Ōhi`a Death (ROD) on the forest bird species of Hawai`i. We are using song recorders to collect vocalizations of forest dwelling species (both native and non-native) in areas of high and low `Ōhi`a mortality to document how species composition may be changing as ROD progresses. I am also beginning my Master's program in Tropical Conservation Biology and Environmental Science at UH Hilo.

Erin Netoskie



Graduated 2019



I grew up in Pittsburgh, PA and have always been interested in animal behavior! I earned by B.S. in wildlife conservation and B.A. in German from Juniata College in 2016. I spent the following year abroad in Austria on a Fulbright research and teaching grant examining the visual signals of foot-flagging frogs at the Vienna Zoo. Now in Hawai`i, my thesis is creating a behavioral landscape of `Ōma`o vocalizations in a naturally fragmented habitat. Through the use of automated telemetry towers and a new technology known as broadcast transmitters to record song, I am able to map vocalizations across the landscape to evaluate resource selection.

Graduated 2019



I am fascinated by how different environmental factors, including habitat fragmentation, noise pollution, and ecological succession can affect animal vocalizations, specifically in bird populations. I got my B.A. in Integrative Biology at the University of California, Berkeley, and worked with Dr. Rosemary Gillespie and Dr. Patrick Hart on a soundscape ecology project studying how the biotic soundscape changes with forest age on Hawai`i Island. I am super excited to be back as a Master's student in the LOHE lab, where I will be studying how helicopter noise affects the vocalizing behavior of birds at Hawai`i Volcanoes National Park.

Born and raised in Hilo, Hawai`i, from a very early age I have had a keen interest in wildlife. As soon as I could walk my family took me hiking and camping in the forest and taught me the names of the Hawaiian plants and birds. In high school I got my first real taste of conservation as a field of study and a possible career during a summer internship with the Hawaiʻi Youth Conservation Corps. I earned my B.A. in Biology at Whitman College in Walla Walla, WA, but came back to Hilo to do my undergraduate thesis research on Palila (Loxioides bailleui) nesting behavior with UH Hilo's PIPES internship program and the USGS Pacific Island Ecosystems Research Center (PIERC). After graduation I solidified my interest in ecology and conservation biology with HYCC Hana Hou internships at Hakalau Forest NWR and Hawai`i Volcanoes National Park (HAVO); volunteer work in restoration ecology for HAVO's Natural Resource Management division; an internship with the USGS PIERC Avian Disease Lab; and a full-time position as a CREST TECC lab/field technician, where I managed the Hart lab and assisted principle investigators Dr. John Price and Dr. Patrick Hart and their graduate students with their research. I am currently pursuing a Master's degree in UH Hilo's TCBES program with generous financial support from the Hau`oli Mau Loa Foundation. I am investigating differences in vocalization between male and female `I`iwi (Vestiaria coccinea).

Growing up on O`ahu, I escaped the city by hiking along the shore and up in the mountain trails of Honolulu. It wasn’t until my first summer back from college that I realized how much the Honolulu of my youth had grown and the places I remember fondly had all but disappeared. I would like to help land managers retain and coexist with the natural Hawai`i that inspired me to continue my education in tropical conservation biology. I will be observing the Pearl Harbor population of Hawaiian Stilt (Himantopus mexicanus knudseni) Ae`o and Hawaiian Coot (Fulica alai) `Alae ke`oke`o to better understand how restored wetlands are being used by Hawaiian waterbirds and the management practices that best sustain a population of waterbirds in Hawai`i.

I grew up in Roseburg, Oregon and first became interested in conservation and environmental issues in high school. I attended Linfield College in McMinnville, Oregon and earned a Bachelor of Science in environmental science and minors in music and biology. I was fortunate enough to engage in undergraduate research with my marine ecology professor and studied the microbiome of Oregon sea sponges. After spending a semester abroad in Cairns, Australia, I fell in love with tropical environments and knew I wanted to study tropical conservation biology in graduate school. I therefore applied and was accepted into University of Hawaii’s Tropical Conservation Biology and Environmental Science Masters program. I’m uncertain as of yet what my graduate research will include, but I know I want it to include tropical conservation. I look forward to developing a research question at University of Hawai`i!

Hi! I’m Tishanna Bailey Ben. I was born and raised on Kaua`i and graduated from Kapaa High school on the east side of the island. I moved to the Big Island in spring 2006 and received my degree in Biology from the University of Hawaiʻi at Hilo. It was during my undergraduate career that I realized that the Big Island has so much to offer in terms of natural resources and environmental research. I started my work with UH Hilo’s TCBES program as a lab/field technician. The position allowed me to assist graduate students with their thesis projects as well as explore my personal interests as an environmental biologist. I’ve had opportunities to assist on a variety of projects, keep up on what’s going on in the research community, gain experience with useful research techniques and travel to beautiful remote and restricted areas. These awesome experiences are just a few of the reasons that I decided to apply to the TCBES program. I plan to start the graduate program in the fall of 2012 under the direction of Dr. Patrick Hart. I am currently exploring potential research projects involving tree rings in the native `Akoko.

The acoustic realm of avian species has received growing recognition from the scientific community in past decades. With the advent of early sound recording technology, researchers were able to begin documenting simple variability in bird acoustics. From there, research has now demonstrated that complex information, such as cultural aspects, are transmitted not only between individuals in a population but over generations as well. Transmission of information has also been shown to decline over time with increased habitat fragmentation in numerous bird species. With my research, I hope to begin documenting acoustic variability and complexity in a family of birds whom has yet to see proper acoustic research: the Hawaiian Honeycreepers. By first looking at variability across elevations and age groups, I hope to progress into possibly revealing a loss in variation and repertoire size across fragmented populations. It is crucial to document the sounds of Hawai`i's precious honeycreepers before its forests become silent forever.

Alex got hooked on birds while attending the University of California, Santa Cruz. After learning how to monitor birds at the Point Reyes Bird Observatory in Northern California, he had his first taste of Hawaiian avifauna banding albatross for the USFWS on Tern Island in the Northwest Hawaiian Islands. He then spent a busy year back on the mainland, surveying desert birds in Arizona, monitoring seabirds on Buldir Island in the western Aleutian chain of Alaska, and surveying for oiled birds in the Gulf of Mexico after the Deepwater Horizon oil spill. He then came back to Hawaii and spent a year with the non-profit, Maui Forest Bird Recovery Project (MFBRP), as an AmeriCorps intern banding and monitoring forest birds. Here he decided he wanted to conduct his Masters research on the endangered `Akohekohe of Maui and subsequent to his internship got a job with their sister organization, the Kaua`i Forest Bird Recovery Project, to learn radio telemetry on endangered Puaiohi and `Akikiki of Kaua`i. He plans to use radio telemetry to examine juvenile dispersal patterns of `Akohekohe in preparation for a future translocation to the newly created Na Kula Natural Area Reserve on Maui.

In 2010 an infestation of Yellow Crazy ants (Anoplolepis gracilipes) was discovered on Johnston Atoll, one of the most remote seabird colonies in the world. In a very short time the ants had reached “supercolony” densities and effectively displaced all ground nesting seabirds within the 135-acre infestation. The US Fish and Wildlife Service (FWS) hired me through their Student Temporary Employment Program (STEP) to put together a field camp and lead a strike team on a 9-month expedition to investigate and address the problem. My thesis research has focused on studying the ecology of the yellow crazy ants, developing control and eradication techniques, and measuring the resulting impacts on the island’s seabird community. FWS has extended my position and I am currently in the middle of my second deployment to Johnston and as of March 2012 we have developed an effective control technique that has decreased the ant population by 99%. The seabird response has been immediate with substantial numbers of red-tailed tropicbirds establishing nests within the bounds of the infested area that they had previously abandoned. My crew of volunteers and I are continuing to monitor seabird reproductive success and working towards an actual complete eradication of the ants from the atoll. After I defend and graduate in Dec-2012, I hope to continue working in the field of island conservation biology.

Christopher Todd



Graduated 2013



Christopher Todd conducted his TCBES research on seasonal movements and feeding ecology of the Hawaiian hoary bat. His research demonstrated how bats in Hawaiʻi seasonally move across an elevation gradient in response to changes in temperature, precipitation, and insect abundance. Hawaiian hoary bats occupy lower elevations during the summer and fall months when warmer temperatures, less rainfall and increased prey are favorable for giving birth and mating. During the rainy winter months Hawaiian hoary bats will move to higher elevations where colder temperatures allow them to induce torpor as a means to conserve energy during periods of infrequent foraging opportunities. Christopher’s Masters Thesis has provided a critical understanding of the ecological and biological factors that influence movements of this cryptic and Endangered species across the island. In addition to his work on bats here in Hawai`i, Christopher has conducted research on bats in Costa Rica, South Africa, the Mariana Islands, and Papua New Guinea. Currently, Christopher is a PhD candidate at The Hawkesbury Institute for the Environment at Western Sydney University in Australia, where his research is focused on addressing important information gaps in the ecology of the Critically Endangered Christmas Island flying-fox (Pteropus natalis).

My current Masters research focuses on Hawaiian forest bird species and their sensitivity to habitat fragmentation. Using a model system of forest fragments (kīpuka) isolated by recent volcanic activity, I am examining relationships between bird density, patch size, isolation, food availability, and forest structure. A better understanding of the ecological needs of Hawaiian birds, including minimum patch size requirements, can help better direct the management and conservation of these species. Prior to coming to UH Hilo, I obtained a B.Sc. in Environment from McGill University in Montreal, Canada. My broader interests include developing better ways to solve complex management issues arising from the competing interests of human development and species conservation.

“Habitat selection of the endangered Hawaiian Goose: a multi-scale approach”


I used satellite telemetry with GPS capacity to track the endangered Hawaiian Goose to identify previously unknown non-breeding season locations, daily movement patterns, and to study habitat use versus availability. My research documented that Nene are reestablishing traditional movement patterns across Hawaiʻi Island, patterns thought to have been lost after a severe population decline in the early 20th Century. Habitat selection analyses revealed dramatic seasonal movements across an elevation gradient, and seasonal shifts between use of remote, native landscapes and alien habitats with substantial human presence. This was among the first studies with avifauna to use satellite telemetry data for high-resolution, fine-scale habitat analyses. Results of this research were used to inform conservation management planning for the Hawaiian Goose by state and federal agencies.

My research investigated the role that feral pigs (Sus scrofa) play in the dispersal of strawberry guava (Psidium cattleianum) seeds throughout a native Hawaiian wet forest and across a gradient in elevation. Also, the characterization of strawberry guava distribution and fruiting phenology along the same elevational gradient was assessed. Results demonstrated that feral pigs spread seeds to areas that do not have established strawberry guava trees and thus they play a major role in the invasion of native Hawaiian forest by strawberry guava. The density of strawberry guava trees, seedlings, and fruits declined with elevation, as did the mean number of seeds per fruit.

While earning my B.S. at Providence College, I became intrigued by the role of plumage ornaments with respect to avian behavioral ecology. During my time as an REU (Research Experience for Undergraduates, NSF) and research assistant in the laboratory of Dr. Ellen Ketterson & Dr. Val Nolan Jr. at Mountain Lake Biological Station (Pembroke, VA), I explored this topic in dark-eyed juncos (Junco hyemalis carolinensis). After graduation, my assistantships have included banding migrants in Nova Scotia, aviculture of endangered Hawaiian birds, radio-telemetry and monitoring of an endangered, finch-billed Hawaiian honeycreeper (Loxiodes bailleui), and nest searching/monitoring of the endangered Maui Parrotbill (Pseudonestor xanthophrys) in high elevation cloud forests in East Maui. My master’s thesis at the University of Hawai`i at Hilo was a continuation of my interest in the roles of plumage coloration and ornamentation in birds. I sampled yellow plumage patches from adult males and females of a common Hawaiian honeycreeper, the Hawai`i `amakihi (Hemignathus virens virens) at eight island-wide sites, which vary by elevation and climate. I used spectrophotometry in order to objectively assess plumage coloration across the entire spectral range. Intraspecific variation in yellow, carotenoid-based plumage (derived directly from diet) could have implications of food availability, evolutionary divergence and natural selection, and even disease status (avian malaria) signaling in Hawai`i `amakihi.

I joined the TCBES program at UH Hilo on 2006 to pursue my interest in the conservation of Hawaiian honeycreepers. For my thesis project, I have examined the mechanisms of passive immunization (a.k.a. maternal antibody) against avian malaria in Hawai`i `amakihi. The speculation is that female `amakihi pass on antibody to their offspring as an added form of resistance to avian malaria. Currently, I am desperately looking for `amakihi nests at different elevations, in order to examine the presence of the malaria antibody in the eggs. The study is an extension of the Biocomplexity Project, for which I was an intern in 2003. Before joining the TCBES program, I also worked on several field ornithology projects in California, Oregon and Hawai`i. I graduated from U.C. Davis in 1999 with a B.S. in Environmental Biology.
