Imagine an individual called “hunter” that expends a good deal of energy to capture a gazelle. As the hunter is consuming his small prey, a second individual called “recipient” approaches and begins feeding peacefully alongside the hunter. A few weeks later the roles reverse, such that the previous recipient has now captured a gazelle, and the previous hunter is taking advantage of the recipien...
Cheetahs exhibit extreme mobility not only in running speed, but also in agility. In particularly, tail-assistive maneuver in chase of a gazelle shows the potential usage of tail in robotic quadruped as well. This talk presents several examples of appendage-assisted dynamic balance in nature along with hypothesized principles. Although the benefits of using additional limbs to augment the agili...
The relationship between environmental change and hominin evolution remains obscure. For the most part, this stems from the difficulty of reconstructing ancient hominin habitats. Bovids are among the most frequently utilized paleoenvironmental indicators, but little is known about the habitat preferences of extinct taxa. It is generally assumed that fossil bovids both ate the same things and oc...
Determining the scale and pattern of, and the influences on, the movements of Mongolian gazelles is important because their numbers and range have been reduced significantly, and their remaining grassland habitat faces further fragmentation and degradation. Therefore, during 2000e2005 we monitored movements of individually marked Mongolian gazelle calves and adult females in the Eastern Steppe ...
The objective of this study was to make an inventory of the ixodid tick species infesting wild animals in three western, semi-arid nature reserves in South Africa. To this end 22 animals in the Kgalagadi Transfrontier Park, 10 in the West Coast National Park and 16 in the Karoo National Park were examined. Fourteen tick species were recovered, of which Hyalomma truncatum, Rhipicephalus exophtha...
