Nests in trees are as good as or better than cliffs for two formerly persecuted, primarily cliff nesting eagles in Spain: a cautionary tale in defining the habitat of range‐restricted or threatened species

open access: yesWildlife Biology, EarlyView.
In the late‐20th century, golden and Bonelli's eagles suffered population declines on the Iberian Peninsula, partly due to human persecution. Habitat assessments – especially for Bonelli's eagles – always found or assumed strong associations with cliffs that provided nesting sites.

Temporal, species‐specific variation in activity patterns of bats (Chiroptera) along a boreal river basin in Västerbotten, Sweden

open access: yesWildlife Biology, EarlyView.
Seasonal variation in photoperiods, energetic demands, and reproductive constraints are expected to strongly influence bat activity at high latitudes, yet empirical evidence from boreal systems is limited. We used passive acoustic monitoring to examine spatial, temporal, and feeding activity patterns of bats along a boreal river basin in Sweden (64°N ...

Camera trap distance sampling for density estimation of tiger prey in a Sumatran ecosystem restoration concession

open access: yesWildlife Biology, EarlyView.
Estimating prey species densities is critical for implementing effective tiger Panthera tigris recovery strategies. Several statistical models exist for density estimation of unmarked species from camera trap data, all of which rely on the random placement of cameras.

A Case Report on Rehabilitation of the Asiatic Black Bear (Ursus thibetanus ussuricus) in the Wild 亚洲黑熊 (Ursus thibetanus ussuricus) 野外放归野化案例报告

open access: yesWildlife Letters, EarlyView.
Asiatic black bears in Russia face conservation threats such as habitat destruction and fragmentation, which exacerbate food shortages caused by crop failures. This study explores an innovative approach to rehabilitating bears that abandon hibernation in mid‐winter due to extreme exhaustion by providing supplemental food near their den sites.
