Shed female caribou antlers extend records of calving activity on the Arctic National Wildlife Refuge by millennia

open access: yesFrontiers in Ecology and Evolution, 2023
Caribou (Rangifer tarandus) have among the longest annual migrations of any terrestrial mammal as they move from winter ranges to spring calving grounds.

The sexual selection of hominin bipedalism [PDF]

open access: yes, 2018
In this article, I advance a novel hypothesis on the evolution of hominin bipedalism. I begin by arguing extensively for how the transition to bipedalism must have been problematic for hominins during the Neogene.

Living under the scope: behavior affects survival in a heavily harvested and long‐lived ungulate

open access: yesWildlife Biology, EarlyView.
The spatiotemporal behavior of game species may play a critical role in their survival throughout the hunting season. Where humans are the most dominant predators, avoidance of landscape features that allow hunter access to hunting grounds can be key to increasing survival.

Addled by antlers: Synchronous disruption to female caribou antler phenology

open access: yesEcosphere
Caribou are the only deer species in which females also grow antlers; however, female antler phenology differs from males. While males grow antlers over summer and hold them through autumn rut, female caribou grow antlers in summer and carry the polished

Ungulate substrate use in fauna passages

open access: yesWildlife Biology, EarlyView.
Fauna passages are increasingly constructed at major roads and railways to mitigate the negative effects of infrastructure and traffic on wildlife. The function of such passages depends on design, including the construction materials, soil, and vegetation.

The challenges of viewpoint-taking when learning a sign language: Data from the 'frog story' in British Sign Language [PDF]

open access: yes, 2020
Little is known about how hearing adults learn sign languages. Our objective in this study was to investigate how learners of British Sign Language (BSL) produce narratives, and we focused in particular on viewpoint-taking.

Estimating red deer Cervus elaphus population density using drones in a steep and rugged terrain

open access: yesWildlife Biology, EarlyView.
Precise and accurate information about population density, crucial for wildlife management, is difficult to obtain for elusive species living in dense forests or steep and inaccessible terrain. Using unmanned aerial vehicles (UAVs), we developed a method for obtaining absolute population estimates of ungulates living in steep, rugged, and partly ...

Delineating seasonal shifts in reindeer habitat and diet selection by integrating GPS telemetry and stable isotope analysis

open access: yesWildlife Biology, EarlyView.
Seasonal changes shape herbivore behaviour by altering forage availability and habitat conditions; however, few studies integrate diet and habitat selection data across temporal scales. This study uses seasonality as a unifying framework to combine fine‐scale GPS‐based habitat selection data with broader‐scale dietary information from stable isotope ...
