Projects

Ecological Diffusion Models & Forecasting

Reaction–diffusion models to predict spread of populations, invasives, and disease. Includes nonlinear/anisotropic diffusion, adaptive monitoring, and links among habitat, movement, and demography. Applications include sea otter recolonization (Alaska) and sage-grouse monitoring (Great Basin).
Representative publications: Williams et al. 2017, 2018; Lu et al. 2020; Eisaguirre et al. 2021; Leach et al. 2022; Eisaguirre et al. 2023a.

Wildlife Demography & Harvest Management

Hierarchical demographic models of survival, reproduction, and movement to quantify density dependence, harvest, and environmental change. Case studies include sage-grouse dynamics, cackling goose harvest, and Golden Eagle survival.
Representative publications: Golden et al. (in review); Acevedo et al. (in review); Williams 2015 (PhD); Byrne 2023 (MS); Pacific Flyway Council (2015).

Predator–Prey Dynamics & Human–Wildlife Conflict

Sea otters and shellfisheries, ravens with anthropogenic subsidies, and black bear conflict under changing snow and frost regimes. Embeds predator–prey dynamics in diffusion frameworks to inform coexistence and policy.
Representative publications: Shoemaker et al. (in review); Brockman et al. (accepted); Eisaguirre et al. 2023b; Williams et al. 2008.

Integrating Movement Ecology Across Scales

Links individual-level telemetry with population-level dynamics to bridge fine-scale behavior and range dynamics; connects step-selection, state-space, and mechanistic diffusion models.
Representative publications: Eisaguirre et al. 2025; Eisaguirre, Williams & Hooten 2024; Keating 2021 (MS).

Statistical & Computational Tools for Ecology

Bayesian model selection, hierarchical abundance/survival models, and open-source software and training that disseminate quantitative tools for ecology.
Representative publications: Blume et al. 2024; Gerber & Williams 2020; Womble et al. 2017.
