Deformation of Earth Materials: An Introduction to the Rheology of Solid Earth
TL;DR: In this article, a comprehensive, unified treatment of the materials science of deformation as applied to solid Earth geophysics and geology is presented in a systematic way covering elastic, anelastic and viscous deformation.

Competition and mutualism among the gut helminths of a mammalian host
TL;DR: Evidence of consistent interspecific interactions in a natural mammalian system is presented through the analysis of parasite intensity data collected from a free-ranging rabbit population, sampled monthly for a period of 23 yr, suggesting that parasite interactions could have profound implications for the dynamics of parasite communities.

Dislocation creep in MgSiO3 perovskite at conditions of the Earth's uppermost lower mantle
TL;DR: It is concluded that, under uppermost lower-mantle conditions, MgSiO3 perovskite deforms by dislocation creep and may therefore contribute to producing seismic anisotropy in rocks at such depths.

Rheology of Crustal Rocks at Ultrahigh Pressure
Bernhard Stöckhert,Jörg Renner +1 more
TL;DR: In this paper, the results of experimental deformation of minerals stable at ultra-high pressure and on the anticipated effect of pressure on deformation mechanisms were used to predict the strength of continental crust during UHP metamorphism.

Diffusion in silicate minerals and glasses: A data digest and guide to the literature
TL;DR: In this article, a compilation of data for diffusion in silicate minerals and glasses is presented along with a "working guide" for its use, along with an outline of diffusion mechanisms, terminology, equations and units, diffusion regimes, factors controlling diffusion rates, measurement techniques, and diffusional behaviour.

Transition region of the Earth's upper mantle
Don L. Anderson,Jay D. Bass +1 more
TL;DR: The Earth's mantle is conventionally divided into three major subdivisions: the shallow mantle, the transition region and the lower mantle, and the question of whether these represent equilibrium phase boundaries in a homogeneous mantle or changes in chemistry is fundamental to many problems in earth sciences as mentioned in this paper.
