Integrating animal experience into state-switching habitat selection models

This paper introduces a state-switching habitat selection model that incorporates animal experience, showing that woodland caribou integrate predation risk over 15 days but food intake over 2 days when deciding to stay or leave an area.

Evolutionary dynamics at the leading edge of biological invasions

The paper uses mathematical models to study how evolutionary trade-offs affect dispersal and spreading speed during species invasions.

Eruptive insect outbreaks from endemic populations under climate change

The paper presents a mechanistic model of mountain pine beetle population dynamics, showing how climate change can shift parameters to eliminate endemic equilibria and trigger outbreaks.

Modeling Mountain Pine Beetle Abundance in Novel Hosts

This study models mountain pine beetle abundance in novel hosts, finding jack pine is less susceptible than lodgepole pine, with lower infestation rates and reproduction.

Modeling Mountain Pine Beetle Abundance and Distribution in a Changing Climate

This study models mountain pine beetle outbreaks under climate change, finding increased infestation probability and numbers with rising temperatures.

Characterizing the speed and severity of mountain pine beetle spread under climate change with a mechanistic model

The paper uses a mechanistic model to simulate mountain pine beetle spread under climate change, finding faster and more severe outbreaks in the future.
