Sweating in the guanaco (Lama guanicoe)
Journal of Thermal Biology, 2001 Sweat glands are present all over the skin, where sweat production varies from 4.98 to 73.36gm(-2)h(-1) of skin. Ambient temperatures between 20 and 33 degrees C are the main stimuli for activation of sweat glands, generating a heat loss ranging from 11.9 to 37% of standing basal metabolic rate.

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

Choosing what is left: the spatial structure of a wild herbivore population within a livestock-dominated landscape [PDF]
PeerJ, 2020 Shrublands and grasslands comprise over 30% of the land surface and are among the most exploited ecosystems for livestock production. Across natural landscapes, the distribution and abundance of wild herbivores are affected by interspecific competition ...

A framework for capturing indirect impacts in site‐level screening for biodiversity risks
Methods in Ecology and Evolution, EarlyView.Abstract Site‐based industrial operations such as mining, oil and gas extraction and renewable energy development are associated with many direct and indirect impacts on biodiversity. Consideration of the full range of these impacts when selecting a buffer distance to approximate the Area of Influence (AoI) of a project is critical for effective ...
