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...

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...

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...

Large Herbivore Nemabiomes: Patterns of Diversity and Sharing

Georgia Titcomb, Johan Pansu, Matthew Hutchinson, Kaia Tombak, Christina Hansen, Chris Baker, Tyler Kartzinel, Hillary Young & Robert Pringle
Amidst global shifts in the distribution and abundance of wildlife and livestock, we have only a rudimentary understanding of ungulate parasite communities and parasite-sharing patterns. We used qPCR and DNA metabarcoding of fecal samples to characterize gastrointestinal nematode (Strongylida) community composition and sharing among 17 sympatric species of wild and domestic large mammalian herbivore in central Kenya. We tested a suite of hypothesis-driven predictions about the role of host traits and phylogenetic relatedness in describing...
