New Zealands lesser short-tailed bat, Mystacina tuberculata, is one of only two bat species to use a true walking gait when maneuvering on the ground. It has been assumed that the specialized terrestrial habits of mystacinids evolved in New Zealand following their isolation there. Absence of native terrestrial mammalian predators in New Zealand has been hypothesized to have facilitated evolution of terrestriality. However, although it is likely that terrestrial foraging by extant Mystacina tuberculate makes it vulnerable to introduced mammalian predators, there is as yet limited available data on the actual risk of terrestriality. Indeed, Lloyd argues that although some individuals may be caught on the ground, generally they would not be easy prey: they are cryptic, fast-moving, with acute hearing and olfaction, and can quickly take flight.

The manuscripts of the eight extant Latin tragedies identify the lays as the Marci Lucii Annei Senecae Tragoediae. Since nobody of that name is known. modern scholars believe the dramas to be the work of Lucius Annaeus Seneca the Younger, the well-known philosopher, orator, and politician. Clearly, the tragedies were written during Seneca's lifetime: internal references to earlier poets, most notably Ovid, indicate that the dramas cannot have been composed prior to the second decade C E, and the plays must have been written by 96 C.E., when Quintilian quotes Medea, one of the tragedies.
It is remarkable, however that Seneca himself never mentions the plays, since there are certainly passages in them that could be used to illustrate points of his philosophy. There are at least two possible explanations In the early Roman Empire, playwrights were sometimes exiled or executed for lines construed as directed against the emperor; thus, Seneca's silence may be simple prudence. But if anyone could safely attach his name to dramas surely it would be Seneca, the emperor's tutor. And although Herrmann offers Seneca's modesty as an explanation, Seneca is not averse to referring to his other writings. The evidence for equating Seneca with the author of the tragedies seems circumstantial.
