Phaedra Budy, PhD
Unit Leader - Utah Cooperative Fish and Wildlife Research Unit
Phaedra is the Unit Leader of the Utah Unit, a Professor of fisheries management and aquatic ecology in the Department of Watershed Sciences at Utah State University (USU) and a faculty member of The Ecology Center at USU. She leads research that fits into an overall framework of evaluating the factors that structure and limit fish populations and communities in both lentic and lotic systems, and also works broadly in the conservation biology, invasion ecology, and food web dynamics of aquatic systems. Her current research covers a wide geographical range including almost all of Utah (from the south of the state up to high elevation points in the Bear River drainage), Nevada, New Mexico, and northern, arctic Alaska and includes many species of salmonids, imperiled native desert fishes (e.g., the "three species"), and numerous warm water lentic fishes. She also dabbles in experimental and adaptive stream restoration and large river management. Phaedra currently teaches advanced graduate level classes in Fish Ecology and most recently Big Ideas in Watershed Sciences.
She holds a B.S. in Limnology from the University of California, Davis and a PhD in Aquatic Ecology from Utah State University.

Trout as native and non-native species: A management paradox Trout as native and non-native species: A management paradox
Native trout are threatened worldwide by introductions of non-native trout that in many cases are themselves threatened within their native range and historical habitats. This chapter focuses on this paradox and addresses how information gained to protect and restore a species in its native range can be used to suppress the same species outside its native range, where it may be invasive...

We ain’t afraid of no ghosts: Tracking habitat interactions and movement dynamics of ghost PIT tags under differing flow conditions in a sand bed river We ain’t afraid of no ghosts: Tracking habitat interactions and movement dynamics of ghost PIT tags under differing flow conditions in a sand bed river
The use of PIT tags has rapidly proliferated since their introduction, and new mobile detection methods have been developed. However, the presence of ghost tags (i.e., PIT tags left in the system after a fish dies) creates uncertainty about the status (live or dead) of tags detected. Herein, we describe our raft-based mobile PIT tag antenna system, which was used to evaluate the...

BioTIME: A database of biodiversity time series for the Anthropocene BioTIME: A database of biodiversity time series for the Anthropocene
MotivationThe BioTIME database contains raw data on species identities and abundances in ecological assemblages through time. These data enable users to calculate temporal trends in biodiversity within and amongst assemblages using a broad range of metrics. BioTIME is being developed as a community-led open-source database of biodiversity time series. Our goal is to accelerate and...

Modeling the fish community population dynamics and forecasting the eradication success of an exotic fish from an alpine stream Modeling the fish community population dynamics and forecasting the eradication success of an exotic fish from an alpine stream
Management actions aimed at eradicating exotic fish species from riverine ecosystems can be better informed by forecasting abilities of mechanistic models. We illustrate this point with an example of the Logan River, Utah, originally populated with endemic cutthroat trout (Oncorhynchus clarkii utah), which compete with exotic brown trout (Salmo trutta). The coexistence equilibrium was...

Evaluating the conservation potential of tributaries for native fishes in the Upper Colorado River Basin Evaluating the conservation potential of tributaries for native fishes in the Upper Colorado River Basin
We explored the conservation potential of tributaries in the upper Colorado River basin by modeling native fish species richness as a function of river discharge, temperature, barrier‐free length, and distance to nearest free‐flowing main‐stem section. We investigated a historic period prior to large‐scale water development and a contemporary period. In the historic period, species...

Brown trout as an invader: A synthesis of problems and perspectives in western North America Brown trout as an invader: A synthesis of problems and perspectives in western North America
Brown trout are one of the most pervasive and successful invaders worldwide and are ubiquitous across the Intermountain West, USA (IMW). This species is the foundation of extremely popular and economically significant sport fisheries despite well-established negative effects on native fishes and ecosystems, resulting in very challenging, and often opposing, conservation and management...

Quantifying long-term population growth rates of threatened bull trout: challenges, lessons learned, and opportunities Quantifying long-term population growth rates of threatened bull trout: challenges, lessons learned, and opportunities
Temporal symmetry models (TSM) represent advances in the analytical application of mark–recapture data to population status assessments. For a population of char, we employed 10 years of active and passive mark–recapture data to quantify population growth rates using different data sources and analytical approaches. Estimates of adult population growth rate were 1.01 (95% confidence...

At the forefront: evidence of the applicability of using environmental DNA to quantify the abundance of fish populations in natural lentic waters with additional sampling considerations At the forefront: evidence of the applicability of using environmental DNA to quantify the abundance of fish populations in natural lentic waters with additional sampling considerations
Environmental DNA (eDNA) sampling has proven to be a valuable tool for detecting species in aquatic ecosystems. Within this rapidly evolving field, a promising application is the ability to obtain quantitative estimates of relative species abundance based on eDNA concentration rather than traditionally labor-intensive methods. We investigated the relationship between eDNA concentration...

Matching watershed and otolith chemistry to establish natal origin of an endangered desert lake sucker Matching watershed and otolith chemistry to establish natal origin of an endangered desert lake sucker
Stream habitat restoration and supplemental stocking of hatchery-reared fish have increasingly become key components of recovery plans for imperiled freshwater fish; however, determining when to discontinue stocking efforts, prioritizing restoration areas, and evaluating restoration success present a conservation challenge. In this study, we demonstrate that otolith microchemistry is an...

Earning their stripes: The potential of tiger trout and other salmonids as biological controls of forage fishes in a western reservoir Earning their stripes: The potential of tiger trout and other salmonids as biological controls of forage fishes in a western reservoir
Maintaining a balance between predator and prey populations can be an ongoing challenge for fisheries managers, especially in managing artificial ecosystems such as reservoirs. In a high-elevation Utah reservoir, the unintentional introduction of the Utah Chub Gila atraria and its subsequent population expansion prompted managers to experimentally shift from exclusively stocking Rainbow...

Assessing conditions influencing the longitudinal distribution of exotic brown trout (Salmo trutta) in a mountain stream: a spatially-explicit modeling approach Assessing conditions influencing the longitudinal distribution of exotic brown trout (Salmo trutta) in a mountain stream: a spatially-explicit modeling approach
Trout species often segregate along elevational gradients, yet the mechanisms driving this pattern are not fully understood. On the Logan River, Utah, USA, exotic brown trout (Salmo trutta) dominate at low elevations but are near-absent from high elevations with native Bonneville cutthroat trout (Onchorhynchus clarkii utah). We used a spatially-explicit Bayesian modeling approach to...
