Data from: Selection for predation, not female fecundity, explains sexual size dimorphism in the orchid mantises

Gavin J. Svenson, Sydney K. Brannoch, Henrique M. Rodrigues, James C. O'Hanlon & Frank Wieland
Here we reconstruct the evolutionary shift towards floral simulation in orchid mantises and suggest female predatory selection as the likely driving force behind the development of extreme sexual size dimorphism. Through analysis of body size data and phylogenetic modelling of trait evolution, we recovered an ancestral shift towards sexual dimorphisms in both size and appearance in a lineage of flower-associated praying mantises. Sedentary female flower mantises dramatically increased in size prior to a transition from...

Data from: Cortical reorganisation during a 30-week tinnitus treatment program

Catherine M. McMahon, Ronny K. Ibrahim & Ankit Mathur
Subjective tinnitus is characterised by the conscious perception of a phantom sound. Previous studies have shown that individuals with chronic tinnitus have disrupted sound-evoked cortical tonotopic maps, time-shifted evoked auditory responses, and altered oscillatory cortical activity. The main objectives of this study were to: (i) compare sound-evoked brain responses and cortical tonotopic maps in individuals with bilateral tinnitus and those without tinnitus; and (ii) investigate whether changes in these sound-evoked responses occur with amelioration of...

Data from: Probabilistic divergence time estimation without branch lengths: dating the origins of dinosaurs, avian flight and crown birds

Graeme T. Lloyd, David W. Bapst, Matt Friedman & Katie E. Davis
Branch lengths—measured in character changes—are an essential requirement of clock-based divergence estimation, regardless of whether the fossil calibrations used represent nodes or tips. However, a separate set of divergence time approaches are typically used to date palaeontological trees, which may lack such branch lengths. Among these methods, sophisticated probabilistic approaches have recently emerged, in contrast with simpler algorithms relying on minimum node ages. Here, using a novel phylogenetic hypothesis for Mesozoic dinosaurs, we apply two...
