Data from: Evidence for hearing loss in amblyopsid cavefishes

Matthew L. Niemiller, Dennis M. Higgs & Daphne Soares
The constant darkness of caves and other subterranean habitats imposes sensory constraints that offer a unique opportunity to examine evolution of sensory modalities. Hearing in cavefishes has not been well explored, and here we show that cavefishes in the family Amblyopsidae are not only blind but have also lost a significant portion of their hearing range. Our results showed that cave and surface amblyopsids shared the same audiogram profile at low frequencies but only surface...

Data from: pavo: an R package for the analysis, visualization and organization of spectral data

Rafael Maia, Chad M. Eliason, Pierre-Paul Bitton, St├ęphanie M. Doucet & Matthew D. Shawkey
1. Recent technical and methodological advances have led to a dramatic increase in the use of spectrometry to quantify reflectance properties of biological materials, as well as models to determine how these colours are perceived by animals, providing important insights into ecological and evolutionary aspects of animal visual communication. 2. Despite this growing interest, a unified cross-platform framework for analyzing and visualizing spectral data has not been available. We introduce pavo, an R package that...

Data from: Environmental associations with gene transcription in Babine Lake rainbow trout: evidence for local adaptation

Kyle W. Wellband & Daniel D. Heath
The molecular genetic mechanisms facilitating local adaptation in salmonids continue to be poorly characterized. Gene transcription is a highly regulated step in the expression of a phenotype and it has been shown to respond to selection and thus may be one mechanism that facilitates the development of local adaptation. Advances in molecular genetic tools and an increased understanding of the functional roles of specific genes allow us to test hypotheses concerning the role of variable...

Data from: A novel hearing specialization in the New Zealand bigeye, Pempheris adspersa

Craig A. Radford, John C. Montgomery, Paul Caiger, Peter Johnston, Jun Lu & Dennis M. Higgs
The New Zealand bigeye, Pempheris adspersa, is a nocturnal planktivore and has recently been found to be an active sound producer. The rostral end of the swim bladder lies adjacent to Baudelot's ligament which spans between the bulla and the cleithrum bone of the pectoral girdle. The aim of this study was to use the auditory evoked potential technique to physiologically test the possibility that this structure provides an enhanced sensitivity to sound pressure in...
