Data from: Wall structure and material properties cause viscous damping of swimbladder sounds in the oyster toadfish Opsanus tauMichael L. Fine, Terrence L. King, Heba Ali, Nehan Sidker & Timothy M. Cameron
Despite rapid damping, fish swimbladders have been modelled as underwater resonant bubbles. Recent data suggest that swimbladders of sound-producing fishes use a forced rather than a resonant response to produce sound. The reason for this discrepancy has not been formally addressed, and we demonstrate, for the first time, that the structure of the swimbladder wall will affect vibratory behaviour. Using the oyster toadfish Opsanus tau, we find regional differences in bladder thickness, directionality of collagen...
Data from: A generalizable energetics-based model of avian migration to facilitate continental-scale waterbird conservationEric V. Lonsdorf, Wayne E.

Lyons, Kirsten Luke, Shannon Still & Brian Tavernia
Conserving migratory birds is made especially difficult because of movement among spatially disparate locations across the annual cycle. In light of challenges presented by the scale and ecology of migratory birds, successful conservation requires integrating objectives, management, and monitoring across scales, from local management units to ecoregional and flyway administrative boundaries. We present an integrated approach using a spatially explicit energetic-based mechanistic bird migration model useful to conservation decision-making across disparate scales and locations. This...
Data from: The genomic landscape of rapid repeated evolutionary adaptation to toxic pollution in wild fishNoah M. Reid, Dina A. Proestou, Bryan W. Clark, Wesley C. Warren, John K.

Atlantic killifish populations have rapidly adapted to normally lethal levels of pollution in four urban estuaries. Through analysis of 384 whole killifish genome sequences and comparative transcriptomics in four pairs of sensitive and tolerant populations, we identify the aryl hydrocarbon receptor–based signaling pathway as a shared target of selection. This suggests evolutionary constraint on adaptive solutions to complex toxicant mixtures at each site. However, distinct molecular variants apparently contribute to adaptive pathway modification among tolerant...
Data from: Neofunctionalization of embryonic head patterning genes facilitates the positioning of novel traits on the dorsal head of adult beetlesEduardo E. Zattara, Hannah A. Busey, David M. Linz, Yoshinori Tomoyasu & Armin P. Moczek
The origin and integration of novel traits are fundamental processes during the developmental evolution of complex organisms. Yet how novel traits integrate into pre-existing contexts remains poorly understood. Beetle horns represent a spectacular evolutionary novelty integrated within the context of the adult dorsal head, a highly conserved trait complex present since the origin of insects. We investigated whether otd1/2 and six3, members of a highly conserved gene network that instructs the formation of the anterior...
