Beyond abundance: the impact of sampling design on effective population size estimates in capercaillie

open access: yesWildlife Biology, EarlyView.
Effective population size (Ne) is a useful parameter to evaluate the long‐term viability of populations. While obtaining enough field data from wild populations to estimate Ne directly is challenging, molecular techniques applied to non‐invasive samples provide an appealing alternative.

The wolf is back! Non‐consumptive effects of the return of a large carnivore on the use of supplementary feeding sites by roe deer

open access: yesWildlife Biology, EarlyView.
Understanding how prey species tradeoff predation risk and resource acquisition is particularly important for advancing our knowledge of predator–prey relationships. We investigated this by studying the use of concentrated anthropogenic resources, namely supplementary feeding sites, by roe deer Capreolus capreolus before and after grey wolf Canis lupus

Quantifying microhabitat selection of snowshoe hares using forest metrics from UAS‐based LiDAR

open access: yesWildlife Biology, EarlyView.
Identifying the spatial and temporal scale at which animals select resources is critical for predicting how populations respond to changes in the environment. The spatial distribution of fine‐scale resources (e.g. patches of dense vegetation) are often linked with critical life‐history requirements such as denning and feeding sites.

Comparing manual and automated methods for identifying individual great gray owls via territorial calls

open access: yesWildlife Society Bulletin, EarlyView.
We compared 2 audio analysis methods: 1) manual spectral analysis, and 2) automated mel‐frequency cepstral coefficients (MFCCs), to identify great gray owls (Strix nebulosa) to individual using territorial calls. The MFCC method was 97.6% accurate at classifying individuals whereas spectral analysis had only a 77.2% accuracy rate.
