We are writing in response to a recent critique by Emerson & Hickerson (2015), who challenge the evidence of a time-dependent bias in molecular rate estimates. This bias takes the form of a negative relationship between inferred evolutionary rates and the ages of the calibrations on which these estimates are based. Here, we present a summary of the evidence obtained from a broad range of taxa t...

The imago and soldier castes of the Neotropical Termitinae species Genuotermes spinifer Emerson are redescribed. The gut anatomy of the worker is described in detail for the first time, and morphological variations in the soldier are noted and illustrated. The known geographical distribution of Genuotermes spinifer is greatly expanded.

This paper attempts to answer three questions: (1) Was Emerson a mystic? (2) If so, what is the nature of his mysticism? (3) How has his understanding of mysticism influenced by Unitarian theology and spiritual practice? In doing so, it draws upon historical and contemporary studies of mysticism and mystical experience, including those of William James, Leigh Eric Schmidt, and Bernard McGinn am...
