Data from: Whole-genome phylogeography of the Blue-faced honeyeater (Entomyzon cyanotis) and discovery and characterization of a neo-Z chromosome

Scott Edwards, John Burley, Sophie Orzechowski & Yun Wa Sin
Whole-genome surveys of genetic diversity and geographic variation often yield unexpected discoveries of novel structural variation, which long-read DNA sequencing can help clarify. Here we report on whole-genome phylogeography of a bird exhibiting classic vicariant geographies across Australia and New Guinea, the Blue-faced honeyeater (Entomyzon cyanotis), and the discovery and characterization of a novel neo-Z chromosome by long-read sequencing. Using short-read genome-wide SNPs, we inferred population divergence events within E. cyanotis across the Carpentarian and...

Robot threat Study 2

Maya Cratsley, Maya Cratsley, Bertram Malle & Malik Boykin
This study will further explore the finding from our initial study in which participants exposed to the idea of highly-skilled robot workers responded to this potential job threat by expressing more negative feelings towards robots, greater anti-robot bias (modeled after a human outgroup bias measure), and lower estimates of robots’ mental capacities compared to those who were presented neutral information about robots. In this study we will be recruiting two specific populations to participate in...

Microbiomes associated with avian malaria survival differ between susceptible Hawaiian honeycreepers and sympatric malaria-resistant introduced birds

Amanda Navine, Kristina Paxton, Eben Paxton, Patrick Hart, Jeffrey Foster, Nancy McInerney, Robert Fleischer & Elin Videvall
Of the estimated 55 Hawaiian honeycreepers (subfamily Carduelinae) only 17 species remain, 9 of which the International Union for Conservation of Nature considers endangered. Among the most pressing threats to honeycreeper survival is avian malaria, caused by the introduced blood parasite Plasmodium relictum, which is increasing in distribution in Hawai`i as a result of climate change. Preventing further honeycreeper decline will require innovative conservation strategies that confront malaria from multiple angles. Research on mammals revealed...

The preservation of cause and effect in the rock record

Daniel Ibarra, Michael D'Antonio & C. Kevin Boyce
Evolutionary events may impact the geological carbon cycle via transient imbalances in silicate weathering, and such events have been implicated as causes of glaciations, mass extinctions, and oceanic anoxia. However, suggested evolutionary causes often substantially predate the environmental effects to which they are linked—problematic when carbon cycle perturbations must be resolved in less than a million years. What is more, the geochemical signatures of such perturbations are recorded as they occur in widely distributed marine...

Woodpecker drum evolution: an analysis of covariation in elements of a multicomponent acoustic display among and within species

Nicole M Moody, Emma K Vivlamore & Matthew J Fuxjager
Multicomponent signals are found throughout the animal kingdom, but how these elaborate displays evolve and diversify is still unclear. Here, we explore the evolution of the woodpecker drum display. Two components of this territorial, sexually selected signal, drum speed and drum length, are used by territory holders to assess the threat level of an intruding drummer. We explore the coevolution of these display components both among and within species. Among species, we find evidence for...

Pigmentation biosynthesis influences the microbiome associated with sea urchins

Gary Wessel, Masato Kiyomoto, Adam Reitzel & Tyler Carrier
Organisms living on the seafloor are subject to encrustations by a wide variety of animal, plants, and microbes. Sea urchins, however, thwart this covering. Despite having a sophisticated immune system, there is no clear mechanism that allows sea urchins to remain clean. Here, by using CRISPR/Cas9, we test the hypothesis that pigmentation biosynthesis in sea urchin spines influences their interactions with microbes in vivo. We have three primary findings. First, the microbiome of sea urchin...

Testing Message Framing to Promote Exercise

Lauren Connell Bohlen, David Williams & Omar Galárraga
The primary aim of this project is to examine the effects of (a) incentives versus no incentives; (b) incentive amount ($100 versus $200), and (c) loss-framed versus gain-framed incentive messages on motivation to attend a fitness facility. A secondary aim is to examine the effects of different aspects of loss-framed messages on exercise motivation. Another secondary aim is to examine mediators and moderators of main effects. A tertiary aim is to pilot the questionnaire packet...

Selection in the city: Rapid and fine scale evolution of urban eastern water dragons

Nicola Jackson, Bethan Littleford-Colquhoun, Kasha Strickland, Barbara Class & Celine Frere
Oceanic archipelagos have long been treated as a petri dish for studies of evolutionary and ecological processes. Like archipelagos, cities exhibit similar patterns and processes, such as the rapid phenotypic divergence of a species between urban and non-urban environments. However, on a local scale, cities can be highly heterogenous, where geographically close populations can experience dramatically different environmental conditions. Nevertheless, we are yet to understand the evolutionary and ecological implications for populations spread across a...
