Assessment of natural signal variation in choruses in the wild and test two hypotheses for why eavesdroppers prefer complex calls suggest increased effectiveness of attack may have played a role favoring the preference for complex calls in eavesdropping heterospecifics.

Investigating the acute phase reaction to a standard lipopolysaccharide (LPS) challenge in Pallas's mastiff bats found no leucocytosis or fever, contributing to a clearer understanding of the innate immune system in bat species and of the coevolution of bats with a wide diversity of pathogens.

It is shown that spiny rats (Proechimys semispinosus) carry a counterpart to HDV that surprisingly does not cause hepatitis and is not linked to HBV, establishing a nonhuman, mammalian deltavirus that occurs as a horizontally transmitted infection, is potentially cleared by immune response, is not focused in the liver, and possibly does not require helper virus coinfection.
Signal Perception in Frogs and Bats and the Evolution of Mating Signals
The data show that female cognition can limit the evolution of sexual signal elaboration in túngara frogs, and both relative attractiveness and relative predation risk decrease because of how receivers perceive and compare stimuli.

Bats perceptually weight prey cues across sensory systems when hunting in noise
It is found that predators that hunt using prey sounds can reduce the negative impact of noise by making use of prey cues conveyed through additional sensory systems, and frog-eating bats preferred and were faster in attacking a robotic frog emitting multiple sensory cues.

The prey-cue/prey-quality associations of a predator that eavesdrops on the sexual advertisement signals of its prey are investigated to find that the predatory bat, Trachops cirrhosus, has a heretofore undescribed ability to reverse its evaluations of the cues that signal preferred prey.

Bats whose trained cue was unreliable and who had a tutor were significantly more likely to preferentially approach the novel cue when compared with bats whose trained Cue was reliable, and to bats that had no tutor.
