Systematic characterization of wing mechanosensors that monitor airflow and wing deformations

Joseph Fabian, Igor Siwanowicz, Myriam Uhrhan, Masateru Maeda, Richard Bomphrey & Huai-Ti Lin
Animal wings deform during flight in ways that can enhance lift, facilitate flight control, and mitigate damage. Monitoring the structural and aerodynamic state of the wing is challenging because deformations are passive, and the flow fields are unsteady; it requires distributed mechanosensors that respond to local airflow and strain on the wing. Without a complete map of the sensor arrays, it is impossible to model control strategies underpinned by them. Here, we present the first...

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...

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...

Spatiotemporal influences of climate and humans on muskox range dynamics over multiple millennia

Elisabetta Canteri
Processes leading to range contractions and population declines of Arctic megafauna during the late Pleistocene and early-Holocene are uncertain, with intense debate on the roles of human hunting, climatic change, and their synergy. Obstacles to a resolution, have included an over reliance on correlative rather than process-explicit approaches for inferring drivers of distributional and demographic change. Using process-explicit macroecological models that integrate modern and fossil occurrence records, spatiotemporal reconstructions of past climatic change, speciesspecific population...

Gene drives for vertebrate pest control: realistic spatial modelling of eradication probabilities and times for island mouse populations

Aysegul Birand, Aysegul Birand, Phillip Cassey, Joshua Ross, James Russell, Paul Thomas & Thomas Prowse
Invasive alien species continue to threaten global biodiversity. CRISPR-based gene drives, which can theoretically spread through populations despite imparting a fitness cost, could be used to suppress or eradicate pest populations. We develop an individual-based, spatially explicit, stochastic model to simulate the ability of CRISPR-based homing and X-chromosome shredding drives to eradicate populations of invasive mice (Mus muculus) from islands. Using the model, we explore the interactive effect of the efficiency of the drive constructs...

Intrinsic traits, social context, local environment, and home range size and fidelity data from a field study of sleepy lizards, 2009 - 2017

Eric Payne, Orr Spiegel, David Sinn, Stephan Leu, Michael Gardner, Stephanie Godfrey, Caroline Wohlfeil & Andrew Sih
Home ranges, the region within which animals interact with their environment, constitute a fundamental aspect of their ecology. Home range (HR) sizes and locations commonly reflect costs and benefits associated with diverse social, biotic and abiotic factors. Less is known, however, about how these factors affect intra-specific variation in HR size or fidelity (the individual’s tendency to maintain the same HR location over time), or if variation in these features emerge from consistent differences among...

Data supplement to: Plant proxy evidence for high rainfall and productivity in the eocene of Australia

Tammo Reichgelt, David Greendwood, Sebastian Steinig, John Conran, David Hutchinson, Daniel Lunt, Leonie Scriven & Jiang Zhu
During the early to middle Eocene, a mid-to-high latitudinal position and enhanced hydrological cycle in Australia would have contributed to a wetter and “greener” Australian continent where today arid to semi-arid climates dominate. Here, we revisit 12 Australian plant megafossil sites from the early to middle Eocene to generate temperature, precipitation and seasonality paleoclimate estimates, as well as net primary productivity (NPP) and vegetation type, based on paleobotanical proxies and compare to early Eocene global...

Geophysical and geochemical evidence for a new mafic magmatic province within the Northwest Shelf of Australia: Supplementary material

Christopher Yule & Carl Spandler
Buried magmatic provinces are rarely identified and difficult to classify. The Northwest Shelf of Australia contains large volumes of potentially interconnected mafic igneous material across several sedimentary basins. However, limited study and a lack of surface exposure have prevented detailed description and classification of these rocks. In this study, the distribution and composition of these mafic igneous rocks is described using an integrated geophysical and geochemical approach, which included over 10,000 km of 2D historical...

Barley fasciated ear genes determine inflorescence meristem size and grain yield

Chengyu Wang, Xiujuan Yang, Yueya Zhang, Chaoqun Shen, Jin Shi, Chongjing Xia, Taohong Fang, Qiang Tu, Ling Li, Xinli Zhou, Dabing Zhang & Gang Li
In flowering plants, the inflorescence meristem (IM) provides founder cells to form successive floral meristems, the precursors of fruits or seeds. Hence, the activity and developmental progression of IM are critical for yield production in cereal crops. IM size is positively associated with spikelet number in some major cereals, like rice (Oryza sativa) and maize (Zea mays). However, the relationship and regulatory mechanism between IM size and grain yield remain unknown in Triticeae tribe. Here,...
