The data were obtained by a method not previously used in investigating farm animals. It consists (Fig. 1) in connecting the respiratory system of the animal to a counterpoised bell filled with oxygen, with the bell freely moving in a water trough which acts as a seal for the enclosed ...

Animals studied The population consisted of 22 healthy adult dogs. Procedures Reflex tear osmolarity was measured in both eyes using the I㏄EN VET osmometer 30 minutes following the Schirmer tear test (STT measurement. Subsequently, two minutes following topical anesthetic application, the lacrimal ...
15.So evidence of sustained rapid growth, even into late juvenile and subadult stages, implies that the animals in question had relatively highbasalmetabolic rates. 所以,即使进入幼年晚期与亚成体阶段,仍持续快速长的证据,暗示这些动物具有相对高的基础代谢率。
Animal species of similar body mass vary widely in basal metabolic rate (BMR). A central problem of evolutionary physiology concerns the anatomical/physiological origin and functional significance of that variation. It has been hypothesized that such interspecific differences in wild animals evolved adapti...
Humans and animals will quickly take action when they expect the action will lead to a reward, and this action reflects their motivation10. In the basal ganglia, the percentage of tonically active neu- rons that respond to an action is higher in the putamen than in the caudate nucleus, ...

In adult animals, the male gonopore with its associated sexual organs expresses distinct muscles. No specific statocyst muscles were found. The muscle mantles of the needle-shaped sagittocysts are situated along the lateral edges of the animal and in the posterior end close to the male gono...
Ornithuromorpha is the most derived avian group in the Early Cretaceous, advanced members of which encompass all living birds (Neornithes). The first known appearance datum of this clade is from the Yixian Formation—the middle phase of the Jehol Biota (e.g., Archaeorhynchus and Yixianornis...
