Characterizing long‐term population conditions of the elusive red tree vole with dynamic individual‐based modeling Open
Old growth forests are declining globally, threatening dependent wildlife. Many arboreal old‐growth obligates, such as the threatened red tree vole, are difficult to monitor for changes in habitat occupancy, and abundance. Yet, conservatio…
Peer Review #2 of "Predicted distribution of a rare and understudied forest carnivore: Humboldt marten (Martes caurina humboldtensis) (v0.1)" Open
Background.Many mammalian species have experienced range contractions.Following a reduction in distribution that has resulted in apparently small and disjunct populations, the Humboldt marten (Martes caurina humboldtensis) was recently des…
Predicted distribution of a rare and understudied forest carnivore: Humboldt marten ( <i>Martes caurina humboldtensis</i> ) Open

Predicted distribution of a rare and understudied forest carnivore: Humboldt martens (<i>Martes caurina humboldtensis</i>) Open
Background A suite of mammalian species have experienced range contractions following European settlement and post-settlement development of the North American continent. For example, while North American martens (American marten, Martes a…
Historical disturbances to rivers appear to constrain contemporary distribution of a river-dependent frog Open
Frogs dependent on lotic environments are sensitive to disturbances that alter the hydrology (e.g., water impoundments), substrate (e.g., debris torrents), and riparian vegetation (e.g., wildfires) of river ecosystems. Although rivers are …
Predator–prey interactions in the canopy Open
Small mammal abundances are frequently limited by resource availability, but predators can exert strong lethal (mortality) and nonlethal (e.g., nest abandonment) limitations. Artificially increasing resource availability for uncommon small…
Predator-prey interactions in the canopy Open
Small mammal abundances are frequently limited by resource availability but predators can exert strong lethal (direct mortality) and non-lethal limitations (e.g. depressed site-level activity). Artificially increasing resource availability…
If a tree falls in a forest: implications of forest structure persistence for the Pacific marten (<i>Martes caurina</i>) Open
A global decline in large trees, largely driven by anthropogenic influences, has potentially dire consequences for cavity‐dependent wildlife. For several species of conservation concern in western North America, including Pacific martens (…
Biotic factors influencing the unexpected distribution of a Humboldt marten (Martes caurina humboldtensis) population in a young coastal forest Open
Pacific martens (Martes caurina) are often associated with mature forests with complex structure for denning, resting, and efficient hunting. Nonetheless, a small isolated population of the Humboldt subspecies of Pacific martens (Martes ca…

Abundance and ecological associations of small mammals Open
Effective conservation and management of small mammals require knowledge of the population dynamics of co‐occurring species. We estimated the abundances, autocorrelations, and spatiotemporal associations of 4 small‐mammal species from 2011…

Response of arboreal rodents to increased availability of nest substrates in young forests Open
Many forest-dependent animals require complex branch and bole structural features as substrates for nesting, and these features may take decades or centuries to develop. In young forests, lack of suitable nest substrates may limit occurren…
Peer Review #1 of "Density and population viability of coastal marten: a rare and geographically isolated small carnivore (v0.1)" Open
Pacific martens (Martes caurina) in coastal forests of Oregon and northern California in the United States are rare and geographically isolated, prompting a petition for listing under the Endangered Species Act.If listed, regulations have …

Complementary Network-Based Approaches for Exploring Genetic Structure and Functional Connectivity in Two Vulnerable, Endemic Ground Squirrels Open
The persistence of small populations is influenced by genetic structure and functional connectivity. We used two network-based approaches to understand the persistence of the northern Idaho ground squirrel (Urocitellus brunneus) and the so…
Using high-resolution short-term location data to describe territoriality in Pacific martens Open
Solitary carnivores in the family Mustelidae are thought to exhibit pronounced intrasexual territoriality, defending space against competitors but tolerating members of the opposite sex. Although mustelids move long distances daily, how su…
Space use, movements, and rest site use by short‐tailed weasels <i>Mustela erminea</i> in managed forests of western Oregon Open
Weasels Mustela spp. are specialized, small predators which demonstrate pronounced differences in size and social status according to sex and age, and these differences may manifest in spatial patterns including home range size and habitat…
