TL;DR: The results suggest that Australasian marsupials have diverged from the ancestral Theria neuronal scaling rules, and support the suggestion that the scaling of average neuronal cell size with increasing numbers of neurons varies in evolution independently of the allocation of neurons across structures.

TL;DR: The addition of microglial cells to mammalian brains is governed by mechanisms that constrain the size of these cells and have remained conserved over 200 million years of mammalian evolution, suggesting that microglia-dependent functional recovery may be particularly difficult in those brain structures and species with high neuronal densities and therefore fewer microglian cells per neuron.

TL;DR: A new species of Cerradomys was described from the sandy plains of the northeastern littoral of Rio de Janeiro State and the southern littral of Espirito Santo State, southeastern Brazil.

TL;DR: The disparity of multivariate ontogenetic allometry in the Echimyidae, a taxonomically diverse rodent family, as well as the effects of size on the evolution of skull ontogeny are reported, disagreeing with the hypothesis that allometric disparities might be mainly adaptive with undetectable phylogenetic signals.

TL;DR: It is shown that occupation of remarkably different ecosystems had a significant impact in the phenotypic evolution of Trinomys, and colonization of the Caatinga was associated with remarkable differentiation and a strong increase in the rates of phenotypesic change.
