Historical museum samples enable the examination of divergent and parallel evolution during invasion

Katarina Stuart, William Sherwin, Jeremy Austin, Melissa Bateson, Marcel Eens, Matthew Brandley & Lee Rollins
During the Anthropocene, Earth has experienced unprecedented habitat loss, native species decline, and global climate change. Concurrently, greater globalisation is facilitating species movement, increasing the likelihood of alien species establishment and propagation. There is a great need to understand what influences a species’ ability to persist or perish within a new or changing environment. Examining genes that may be associated with a species’ invasion success or persistence informs invasive species management, assists with native species...

Data for: Two is better than one: Coupling DNA metabarcoding and stable isotope analysis improves dietary characterizations for a riparian-obligate, migratory songbird

Brandon Hoenig, Brian Trevelline, Andrea Kautz, Steven Latta & Brady Porter
While an increasing number of studies are adopting molecular and chemical methods for dietary characterization, these studies often employ only one of these laboratory-based techniques; an approach which may yield an incomplete, or even biased, understanding of diet due to each method’s inherent limitations. To explore the utility of coupling molecular and chemical techniques for dietary characterizations, we applied DNA metabarcoding alongside stable isotope analysis to characterize the dietary niche of breeding Louisiana waterthrush (Parkesia...

Using convolutional neural networks to efficiently extract immense phenological data from community science images

Rachel Reeb, Naeem Aziz, Samuel Lapp, Justin Kitzes, J. Mason Heberling & Sara Kuebbing
Community science image libraries offer a massive, but largely untapped, source of observational data for phenological research. The iNaturalist platform offers a particularly rich archive, containing more than 49 million verifiable, georeferenced, open access images, encompassing seven continents and over 278,000 species. A critical limitation preventing scientists from taking full advantage of this rich data source is labor. Each image must be manually inspected and categorized by phenophase, which is both time-intensive and costly. Consequently,...

Transcript- and annotation-guided genome assembly of the European starling

Katarina Stuart, Richard Edwards, Yuanyuan Cheng, Wes Warren, Dave Burt, William Sherwin, Natalie Hofmeister, Scott Werner, Gregory Ball, Melissa Bateson, Matthew Brandley, Katherine Buchanan, Phillip Cassey, David Clayton, Tim De Meyer, Simone Meddle & Lee Rollins
The European starling, Sturnus vulgaris, is an ecologically significant, globally invasive avian species that is also suffering from a major decline in its native range. Here, we present the genome assembly and long-read transcriptome of an Australian-sourced European starling (S. vulgaris vAU), and a second North American genome (S. vulgaris vNA), as complementary reference genomes for population genetic and evolutionary characterisation. S. vulgaris vAU combined 10x Genomics linked-reads, low-coverage Nanopore sequencing, and PacBio Iso-Seq full-length...

Pretty cool beetles: Can manipulation of visible and near-infrared sunlight prevent overheating?

Laura Ospina Rozo, Jegadesan Subbiah, Ainsley Seago & Devi Stuart-Fox
Passive thermoregulation is an important strategy to prevent overheating in thermally challenging environments. Can the diversity of optical properties found in Christmas beetles (Rutelinae) be an advantage to keep cool? We measured changes in temperature of the elytra of 26 species of Christmas beetles, exclusively due to direct radiation from a solar simulator in visible (VIS: 400–700 nm) and near-infrared (NIR: 700–1700 nm) wavebands. Then, we evaluated if the optical properties of elytra could predict...
