A high‐altitude thermal infrared method for estimating moose abundance and demography in Rocky Mountain National Park, USA

open access: yesWildlife Biology, EarlyView.
Resource managers require accurate estimates of large herbivore abundance and demography to maintain ecological integrity. Common methods to count these species, including observations from low altitude helicopter flights, may conflict with other protected area management objectives and struggle to produce precise estimates for more cryptic species. To

Assessing habitat suitability for black grouse broods at the bioregional scale

open access: yesWildlife Biology, EarlyView.
The black grouse Lyrurus tetrix, a galliform species emblematic of the European Alps, is currently threatened by habitat change, particularly given the closure of heathland linked to the rising tree line at higher altitudes. The presence of heathlands in good ecological condition is, however, imperative for the species' reproduction.

Mountain sport activities, affective state, and mental health – A narrative review

open access: yesCurrent Issues in Sport Science
A large body of literature indicates that physical activity in general is associated with a variety of health benefits. Mountain sport activities (e.g., mountain hiking, climbing, mountaineering, or skiing) are considered popular modalities of physical ...

Comparative evaluation of noninvasive DNA sampling and line transect surveys for spring density estimation of black grouse and capercaillie

open access: yesWildlife Biology, EarlyView.
Reliable abundance estimates provide essential information in ecology, conservation and management of many wild grouse populations. In this 3‐year study, we comparatively evaluate the suitability of traditional line transect distance sampling of flushed birds versus a spatial capture–recapture survey with noninvasive DNA samples for individual ...

Monitoring wildlife using long‐endurance solar‐electric UAVs

open access: yesWildlife Biology, EarlyView.
This report discusses the effectiveness of using small solar‐electric UAV (uncrewed aerial vehicles) for aerial wildlife monitoring. We review four years of aerial wildlife monitoring missions using a 5.5‐m wingspan, solar‐electric UAV that was equipped with a gimballed IR/RGB camera.

Using a live‐streaming webcam to assess the behavioural responses of waterbirds to changes in the density of swans Cygnus spp.

open access: yesWildlife Biology, EarlyView.
Wildlife research has benefitted from the development of new methods that allow data to be collected remotely, with less disturbance to focal animals. The proliferation of livestreaming webcams, for example, those used by nature reserves for public engagement purposes, have offered new possibilities for the study of wildlife behaviour.

Experimental assessment of large mammal population estimates from airborne thermal videography

open access: yesWildlife Biology, EarlyView.
Wildlife resource management requires reliable, fast, and affordable methods of surveying wildlife populations to develop and adaptively adjust policies. Thermal video from drones can yield high rates of detection over large areas with relative speed and safety.

Vog: Using Volcanic Eruptions to Estimate the Health Costs of Particulates

open access: yesThe Economic Journal, EarlyView., 2018
The negative consequences of long‐term exposure to particulate pollution are well established but a number of studies find no effect of short‐term exposure on health outcomes. The high correlation of industrial pollutants complicates the estimation of the impact of individual pollutants on health.

Climate Change and (Mal)Adaptation in Tourism‐Intensive Alpine Regions

open access: yesThe Political Quarterly, EarlyView.
Abstract Tourism, especially in winter, accounts for a large share of economic income in Alpine regions. At the same time, these regions are more severely affected by climate change, leading to shorter winter seasons and reduced snow cover. This presents a pressing issue for areas reliant on income from winter tourism through activities such as skiing.
