The Anatomical Record, EarlyView.Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

The Anatomical Record, EarlyView.Abstract Muscle architecture is a major determinant of muscle performance and, in mammalian lineages, has been correlated with both feeding ecology and locomotor behaviors. Over the past decade, contrast‐enhanced micro‐CT (DiceCT) has emerged as an alternative to traditional dissection‐based measurement.

The Anatomical Record, EarlyView.Abstract Neuroanatomical research has progressed considerably in several vertebrate lineages, yet studies of reptilian brain morphology remain markedly underdeveloped. Here we provide the first description of macroscopic brain anatomy and its ontogeny in the viperid Bothrops moojeni, based on a sample of seven individuals.

Occurrence of Planetary Rings with Shepherds
Celestial Mechanics and Dynamical Astronomy, 2001 We consider the system of planetary rings with shepherds as a restricted three or four-body problem, neglecting interactions between ring particles. We show that the generic occurrence of rings for the case of rotating short-range potentials can be extended to the case of gravitational potentials.

The Dynamics of Planetary Rings
Annual Review of Astronomy and Astrophysics, 1982The discovery of ring systems around Uranus and Jupiter, and the Pioneer and Voyager spacecraft observations of Saturn, have shown that planetary rings are both more common and more complex than previously suspected. These ring systems, interesting in their own right, also serve as prototypes for more massive disk systems such as accretion disks ...

The physics of planetary rings
Soviet Physics Uspekhi, 1990A review of the collisional, collective, and resonance phenomena in planetary rings is presented. The following questions are examined: the reasons for the existence of planetary rings and the properties of a typical particle, the collisional breaking of loose bodies, and the azimuthal asymmetry effect for the rings of Saturn.

Philosophical Transactions of the Royal Society of London. Series A: Physical and Engineering Sciences, 1994
Abstract The dynamics of planetary rings are reviewed in the light of data derived from the recent spacecraft missions to the outer planets. It is shown that although the ring systems of Jupiter, Saturn, Uranus and Neptune display a great diversity of phenomena and dynamical structures, they have many features and problems in common ...

Annual Review of Earth and Planetary Sciences, 1993
The rings in the solar system and the mathematical and physical approaches to understanding them are described. The variety of ring phenomena revealed in recent years from space and earth-based observations is emphasized. Ideas for the recent history of rings are examined in some detail.

The Charging of Planetary Rings
Space Science Reviews, 2008This chapter will review what is known about the charging of planetary rings, in particular the sum of the individual currents from the time-varying charge dQ/dt, of the planetary ring particle. For the smallest ring particles, in addition to checking the plasma conditions for the charging currents, one must consider if collective effects in the ring ...
