Published: 9 March 2021
...Delyle T. Polet ABSTRACT Many quadrupedal mammals transition from a four-beat walk to a two-beat run (e.g. trot), but some transition to a four-beat run (e.g. amble). Recent analysis shows that a two-beat run minimizes work only for animals with a small pitch moment of inertia (MOI), though...

... functions of the oral vocal tract only or of the nasal vocal tract only. This indicates that the nasal and oral vocal tracts are both simultaneously involved in the production of a non-human mammal vocalization, and suggests that the potential for nasalization in putative oral loud calls should be carefully...

To examine this, we conducted an inverse dynamics analysis in the sagittal and frontal planes, using ground...

...Clare Stawski; Julia Nowack; Gerhard Körtner; Fritz Geiser ABSTRACT Recent work has shown that the use of torpor for energy conservation increases after forest fires in heterothermic mammals, probably in response to the reduction of food. However, the specific environmental cues for this increased...

Mediolateral forces were significantly higher than would be expected for a large erect mammal, almost to the extent of a sprawling crocodilian...

Here, we tested the hypothesis that shaving off 50% of the dorsal pelage should effectively increase energy expenditure...
