TL;DR: Repeated origins of angiosperm-feeding beetle lineages are associated with enhanced rates of beetle diversification, indicating a series of adaptive radiations.

TL;DR: The adaptive-zone hypothesis predicts that if multiple lineages have invaded a new adaptive zone, they should be consistently more diverse than their (equally old) sister groups, when the latter retain the more primitive way of life.

TL;DR: A phylogeny of beetles based on DNA sequence data from eight nuclear genes, including six single‐copy nuclear protein‐coding genes, for 367 species representing 172 of 183 extant families provides a uniquely well‐resolved temporal and phylogenetic framework for studying patterns of innovation and diversification in Coleoptera.

TL;DR: The evidence for Ehrlich and Raven's postulate that rapid diversification follows innovation in plant defense is quantified by comparing the diversities of lineages that have independently evolved canal systems with their sister groups for as many plant lineages as current taxonomic evidence allows.

TL;DR: In this article, it was shown that the growth rate of the most rapidly growing instability is linearly proportional to the surface meridional temperature gradient, and the coefficient of proportionality is also easily determined.
