Thermal imagery for census of ungulates [PDF]

open access: yes
A Daedalus thermal linescanner mounted in a light single engine aircraft was used to image the entire 270 square kilometers within the fenced perimeter of ElK Island Park, Alberta, Canada. The data were collected during winter, 1976 in morning and midday

Chimpanzee hunting behavior [PDF]

open access: yes, 2007
The pursuit, capture and consumption of small-and medium-sized vertebrates, appears to be typical of all chimpanzee (Pan troglodytes) populations, although large variation exists. Red colobus monkeys (Piliocolobus sp.) appear to be the preferred prey but

Effects of large herbivores on grassland arthropod diversity [PDF]

open access: yes, 2015
Both arthropods and large grazing herbivores are important components and drivers of biodiversity in grassland ecosystems, but a synthesis of how arthropod diversity is affected by large herbivores has been largely missing. To fill this gap, we conducted

Ancient collagen reveals evolutionary history of the endemic South American ‘ungulates’

open access: yesProceedings of the Royal Society B: Biological Sciences, 2015
Since the late eighteenth century, fossils of bizarre extinct creatures have been described from the Americas, revealing a previously unimagined chapter in the history of mammals.

Dynamics of postnatal bone development and epiphyseal synostosis in the caprine autopod

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Bones develop to structurally balance strength and mobility. Bone developmental dynamics are influenced by whether an animal is ambulatory at birth. Precocial species, which are ambulatory at birth, develop advanced skeletal maturity in utero and experience postnatal development under mechanical loading.

A comparison of four different methods to estimate population size of Alpine marmot (Marmota marmota) [PDF]

open access: yes, 2017
Obtaining reliable information on animal abundance in mountainous landscapes is challenging. Highly heterogeneous habitats tend to reduce detection probabilities, and the three-dimensional, rugged nature of the terrain poses severe limits to the ...

The difference conservation makes to extinction risk of the world's ungulates

open access: yesConservation Biology, 2015
Previous studies show that conservation actions have prevented extinctions, recovered populations, and reduced declining trends in global biodiversity.

Studying interspecific population synchrony: current status and future perspectives

open access: yesEcography, EarlyView.
Interspecific population synchrony, or co‐fluctuations in the population dynamics and demographic parameters of different species, is an important ecological phenomenon with major implications for the stability of communities and ecosystems. It is also central in the context of biodiversity loss, as interspecific synchrony can influence how ecological ...

Capturing and radio ear‐tagging neonatal vicuñas

open access: yesWildlife Society Bulletin, 2012
We used and evaluated the effectiveness of a hand‐capture technique to capture and mark neonatal vicuñas (Vicugna vicugna) at San Guillermo National Park, west‐central Argentina. We captured and marked 98 neonates during 5–31 January, 2008–2010.
