Blake Lowrey, Ph.d.
My research focuses on migration and disease ecology as well as the habitat requirements of temperate ungulates. I use modern techniques, software, and applications to address important ecological questions that support species management and ecosystem conservation.

USGS Chronic Wasting Disease Research at NOROCK
Chronic wasting disease (CWD) is a growing management issue in the U.S. and has been detected in 36 states as of April 2025, including many western states. There is no cure or vaccine for CWD, and the disease threatens economically important animals like elk and deer. NOROCK scientists have taken a multi-pronged approach to develop actionable science including 1) evaluating CWD management options...
The influence of natural mineral licks on wildlife disease dynamics
Some locations on the landscape can aggregate animals of multiple species and could become hotspots of disease transmission. One example of this are areas of localized concentrations of minerals that animals like deer, elk, bighorn sheep, and mountain goats use and diseases like chronic wasting disease or respiratory diseases could spread among or within species who use natural mineral licks...

Expression and mechanisms of behavioral plasticity in large mammals Expression and mechanisms of behavioral plasticity in large mammals
Behavioral plasticity, the alteration of behavior in response to stimuli, is becoming increasingly important in the context of human-induced rapid environmental change. Theoretical and empirical studies suggest that the expression and magnitude of behavioral plasticity are likely facilitated or constrained primarily by two factors: environmental variation and endogenous traits such as...

Estimating ungulate migration corridors from sparse movement data Estimating ungulate migration corridors from sparse movement data
Many ungulates migrate between distinct summer and winter ranges, and identifying, mapping, and conserving these migration corridors have become a focus of local, regional, and global conservation efforts. Brownian bridge movement models (BBMMs) are commonly used to empirically identify these seasonal migration corridors; however, they require location data sampled at relatively frequent...

Infection–nutrition feedbacks: Fat supports pathogen clearance but pathogens reduce fat in a wild mammal Infection–nutrition feedbacks: Fat supports pathogen clearance but pathogens reduce fat in a wild mammal
Though far less obvious than direct effects (clinical disease or mortality), the indirect influences of pathogens are difficult to estimate but may hold fitness consequences. Here, we disentangle the directional relationships between infection and energetic reserves, evaluating the hypotheses that energetic reserves influence infection status of the host and that infection elicits costs...

Conserving habitat for migratory ungulates: How wide is a migration corridor? Conserving habitat for migratory ungulates: How wide is a migration corridor?
Conserving migratory ungulates relies on the analysis of GPS collar data and associated maps of migration corridors to inform management and policy actions. Current methods for identifying migratory corridors use complex statistical models designed to account for movement uncertainty rather than estimating the amount of space required by animals to migrate. Furthermore, such methods can...
