TL;DR: It is shown that maternally transmitted endosymbionts can severely depress levels of mtDNA diversity within an infected host species, while accelerating the rate of divergence among mtDNA lineages in different species.

TL;DR: It is shown that hard-object feeding cannot explain the extreme morphology of Paranthropus boisei, and analysis of long-term dietary plasticity in an animal model suggests year-round reliance on tough foods requiring prolonged postcanine processing in P. boISEi.

TL;DR: This work reports the isolation and identification of microsatellite sequences from multiple genomic libraries for A. aegypti and identifies 6 single-copy simple microsatellites from 3 plasmid libraries enriched for (GA)(n), (AAT)(n, and (TAGA)(n) motifs from A.

TL;DR: The authors used experimental diet manipulation to examine the life-history trajectory of plasticity in the feeding complex of a model organism, the white rabbit (Oryctolagus cuniculus), and demonstrated that the jaws of weanlings and young adults exhibit similar increases in relative bone cross-sectional areas in response to the introduction of mechanically challenging foods into their diets.

TL;DR: It is demonstrated that toughness does not, by itself, underlie increases in cyclical loading and loading duration, and instead, tough foods may be associated with such jaw-loading patterns because they must be processed in greater volumes owing to their lower nutritive quality and for longer periods of time to increase oral exposure to salivary chemicals.
