Tall willow thickets return to northern Yellowstone

open access: yesEcosphere, 2020
Northern Yellowstone National Park provides an example of passive restoration, as wetlands and riparian areas there lost most tall willows in the 20th century, due to intensive herbivory by elk (Cervus canadensis).

Import and presence of wapiti (Cervus canadensis) in Sweden [PDF]

open access: yes, 2022
En kombination av jaktlagstiftningen under 1700-talets senare hälft, illegal jakt samt befolkningsökning i Sverige resulterade i en minskad population av stora hjortdjur i Sverige.

A comparison of thermal drones and camera trap population estimates for Sitka black‐tailed deer in Alaska

open access: yesWildlife Biology, EarlyView.
One of the most difficult challenges for wildlife managers is reliably estimating wildlife populations. Camera traps combined with spatial capture–recapture (SCR) models are a popular tool for population estimation. They have limitations, however, including long data processing times.

The Protection and Management of Wapiti in Desert Oases: Bare Land Poses a Limitation to Wapiti Conservation

open access: yesBiology
The Helan Mountains, situated in the heart of the desert, act as a dividing line between China’s arid and semi-arid zones. Often referred to as a “desert oasis”, they create an ecological island with a uniquely distinctive geographical location, making ...

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

One size does not fit all: Genetic considerations from the Missouri elk restoration

open access: yesConservation Science and Practice, 2022
Population restoration is an inherently costly conservation practice typically reliant on animal translocations. There are many approaches to translocation and consideration is paid to understanding how various translocation models influence restoration ...

Migration of Elk (Cervus canadensis) and Barriers to Movement

open access: yes, 2023
Movement patterns of animals are varied, complex, and can be influenced by environmental and anthropogenic factors. One form of animal movement, migration, is influenced by environmental factors that alter the timing, duration, intensity, and likelihood ...

Born to die: pack and population level estimates of wolf pup survival and recruitment in the Greater Voyageurs Ecosystem

open access: yesWildlife Biology, EarlyView.
Wolf pup Canis lupus survival is a key driver of wolf population dynamics that remains poorly understood, especially in forested systems, because wolf pups are difficult to monitor. We used a combination of pup counts at dens and remote camera observations to estimate annual survival and recruitment of wolf pups in the Greater Voyageurs Ecosystem, MN ...

New Record of Terminal Pleistocene Elk/Wapiti (Cervus canadensis) from Ohio, USA

open access: yes, 2021
The earliest appearance of elk/wapiti (Cervus canadensis) in eastern North America is not thoroughly documented due to the small number of directly dated remains. Until recently, no absolute dates on elk bone older than 10,000 14C yr BP (11,621 to 11,306

Interactions between Elk (Cervus canadensis) and invasive Feral Swine (Sus scrofa) on the Canadian Prairies

open access: yes, 2020
Elk (Cervus canadensis), a native species on the Canadian Prairies, makes extensive use of agro-ecosystems. Feral Swine (Sus scrofa) is a highly invasive species introduced to western Canada in the late 1980s; it is now endemic and rapidly expanding its ...
