Captivity

Captivity selects for smaller eyes

combination of kinetic proofreading and induced fit in tRNA selection provides a suitable balance between fidelity and rapid elongation rates. If we take the simplest case of kinetic proofreading, where there are no differences in forward rate constants introduced by induced fit — where k 3 and k 5 are equivalent for both cognate and near-cognate tRNAs — significant discrimination between cogna...

Captivity humanizes the primate microbiome.

The primate gastrointestinal tract is home to trillions of bacteria, whose composition is associated with numerous metabolic, autoimmune, and infectious human diseases. Although there is increasing evidence that modern and Westernized societies are associated with dramatic loss of natural human gut microbiome diversity, the causes and consequences of such loss are challenging to study. Here we ...

Captivity of mean-field systems∗

The aim of this work is to establish the stability of mean-field system under non-convex confining potential. A mean-field system corresponds to a system of N particles in weak interaction and confined by an exterior force. With our hypotheses, it is a Kolmogorov diffusion with potential Υ N . Exit time of these systems have been studied in details in the smallnoise limit. Here, we will deal wi...

The Three-Dimensional Morphological Effects of Captivity

Many captive animals are fed diets that are drastically different in mechanical properties than their wild diet. Most captive pantherines are fed a nutritionally supplemented diet consisting almost entirely of ground meat. While many zoos supplement this diet with bones, the fact remains that large captive felids are fed diets that require substantially less masticatory effort than those of the...
