An individual-based modelling approach to estimate landscape connectivity for bighorn sheep (Ovis canadensis) [PDF]
PeerJ, 2016 Background. Preserving connectivity, or the ability of a landscape to support species movement, is among the most commonly recommended strategies to reduce the negative effects of climate change and human land use development on species.

Harnessing cross-species alignment to discover SNPs and generate a draft genome sequence of a bighorn sheep (Ovis canadensis) [PDF]
, 2015 Background: Whole genome sequences (WGS) have proliferated as sequencing technology continues to improve and costs decline. While many WGS of model or domestic organisms have been produced, a growing number of non-model species are also being sequenced ...

Bighorn Sheep and Mountain Goats
, 2023 Abstract Bighorn sheep (Ovis canadensis), and to a lesser extent mountain goats (Oreamanos americanus), historically occupied much of the mountainous rangelands of western North America. Both ungulates inhabit rugged terrain and feed on grasses, forbs, and browse.

AccelerometerBehavior: R Package for Classifying Ungulate Behaviors Into Three States. [PDF]
Ecol EvolWe provide an R package, AccelerometerBehavior, which facilitates the classification of acceleration data into behavioral states using field‐validated models for ungulates. Our package provides the supervised models so users do not need their own observation data for model training.

Ecological Effects of Fear: How Spatiotemporal Heterogeneity in Predation Risk Influences Mule Deer Access to Forage in a Sky‐Island System [PDF]
, 2019 Forage availability and predation risk interact to affect habitat use of ungulates across many biomes. Within sky‐island habitats of the Mojave Desert, increased availability of diverse forage and cover may provide ungulates with unique opportunities to ...

Predation impedes recovery of Sierra Nevada bighorn sheep
California Fish and Wildlife Journal, 2021 Translocation of animals into formerly occupied habitat is a key element of the recovery plan for Sierra Nevada bighorn sheep (Ovis canadensis sierrae), which are state (California) and federally listed as endangered. However, implementing Sierra bighorn

Behavior‐specific habitat models as a tool to inform ungulate restoration
Ecosphere, 2021 Across North America, many ungulate species that experienced historic population declines and range contractions are now broadly distributed across their native ranges after the implementation of successful restoration programs.

Multi-scale Orderless Pooling of Deep Convolutional Activation Features [PDF]
, 2014 Deep convolutional neural networks (CNN) have shown their promise as a universal representation for recognition. However, global CNN activations lack geometric invariance, which limits their robustness for classification and matching of highly variable ...
