Accounting for unknown behaviors of free-living animals in accelerometer-based classification models: Demonstration on a wide-ranging mesopredator
This work developed a modeling approach to predict behaviors of wolverines from collar-mounted accelerometers using Support Vector Machines that can achieve a model-averaged accuracy of 98.3%, with high predictive performance for the behaviors resting, running, scanning, tearing at food, and transferring items with the mouth.

An integrated dietary assessment increases feeding event detection in an urban carnivore
Urbanisation radically changes habitats and alters available resources. Populations of large, highly mobile species are often extirpated at the urban-wildland interface, while species likeExpand
Identification of carnivore kill sites is improved by verified accelerometer data
Collar-mounted accelerometers can improve identification of predation sites for some carnivores as compared to use of GPS and landscape informed covariates alone and increase the understanding of predator–prey relations. Expand
Prey availability and ambient temperature influence carrion persistence in the boreal forest.
The results demonstrate that vertebrate scavenging communities are sensitive to changes in species' demography and environmental change, and that future assessments of food web dynamics should consider links established through scavenging. Expand
Bat activity and richness in beetle-killed forests in southern British Columbia
Wildlife species exhibit changes in behavior, population dynamics, and abundance after disturbances to forests. In western North America, large swathes of dead trees have resulted from unusuallyExpand
Determining the diet of an African mesocarnivore, the caracal: scat or GPS cluster analysis?
A combination of GPS cluster visitation and scat analysis is recommended to determine the diet of caracal and other mesocarnivores across a range of prey sizes. Expand
Less is more: On‐board lossy compression of accelerometer data increases biologging capacity
It is argued that this type of lossy data compression can be a well‐considered choice in study situations where limitations in energy and storage space of the device pose a problem. Expand

Soundgen is an open-source R package that synthesizes nonverbal vocalizations based on meaningful acoustic parameters, which can be specified from the command line or in an interactive app and may prove useful for any studies that require precise control over the acoustic features of nonspeech sounds, including research on animal vocalizations and auditory perception.

Use of Acceleration and Acoustics to Classify Behavior, Generate Time Budgets, and Evaluate Responses to Moonlight in Free-Ranging Snowshoe Hares
Snowshoe hare behavior was classified into four categories using low frequency accelerometry, with an overall model accuracy of 88%, and acoustic recordings to three categories (silence, hopping, and chewing) with an accuracy of 94%. Expand
