About

Conservation | Behavior | Sensory

I am a conservation behavioral ecologist fascinated by the unique ways animals communicate and perceive the world around them. My research focuses on how our understanding of animal's sensory modalities can inform conservation efforts. Most of my research is on birds, particularly seabirds, and aquatic systems.

Research

Conservation & behavior in seabirds

My research has focused on understanding anthropogenic causes of decline in birds, particularly in seabirds. I have studied techniques for applied conservation using sensory behavior. These techniques have included acoustic and odor stimuli for recovery plans of native and threatened seabirds, and population estimates of poorly understood and cryptic species.

Marine conservation around human activity

Major threats to birds at-sea often include stimuli that act as sensory traps. For example, stimuli from fishing vessels and artificial light at night (ALAN) can increase risk to foraging or migrating birds. My research looks at ways that seabirds may be impacted by human activity (i.e. ALAN, marine renewable energy, fishing) while testing approaches that can be implemented by industry and managers for conservation successes.

Sensory conservation approach to PNW aquatic ecosystems

Urban aquatic ecosystems in the Pacific Northwest are impacted by invasive species. My lab studies the population and impact of the invasive African clawed frog (Xenopus laevis) on native aquatic species, including endangered and culturally important salmonids. We use sensory and behavioral approaches to search for best practice mitigation methods.

Lab

Dave Anderson, Research Technician

Dave has been managing animal care in the lab and performing experiments on native biocontrols for invasive frogs.

Quin Butler, Undergraduate Research Assistant

Quin has been working on a variety of projects in the lab including the impact of fences on newt migration, and animal care in the lab.

Olivia Cervantez, Undergraduate Research Assistant

Olivia is performing behavioral experiments to understand if native amphibians respond the same to chemical cues of native predators compared to invasive predators.

Jacie Fabela, Undergraduate Research Assistant

Jacie's research has been related to population dynamics of invasive African clawed frogs including elements of size variation in trapping and diet. She also is involved in lab animal care.

Kreshele Contreras, Undergraduate Research Assistant

Kreshele works on understanding population dynamics, trapping and animal husbandry of invasive African clawed frogs.

Ariel Heswall, PhD student (based at University of Auckland)

Ariel's research has focused on vision and visual cues in seabirds and how anthropogenic sources of visual cues (e.g. ALAN) create sensory traps.

Senior Thesis Students (2022-2023)

Senior thesis students in our lab are investigating aspects of the foraging behavior of African clawed frogs, and their potential risk to PNW species of conservation concern (e.g. salmonids)
