Data from: Reconfiguration of functional brain networks and metabolic cost converge during task performance

Andreas Hahn, Michael Breakspear, Lucas Rischka, Wolfgang Wadsak, Godber Godbersen, Verena Pichler, Paul Michenthaler, Thomas Vanicek, Marcus Hacker, Siegfried Kasper, Rupert Lanzenberger & Luca Cocchi
The ability to solve cognitive tasks depends upon adaptive changes in the organization of whole-brain functional networks. However, the link between task-induced network reconfigurations and their underlying energy demands is poorly understood. We address this by multimodal network analyses integrating functional and molecular neuroimaging acquired concurrently during a complex cognitive task. Task engagement elicited a marked increase in the association between glucose consumption and functional brain network reorganization. This convergence between metabolic and neural processes...

eDNA metabarcoding survey reveals fine-scale coral reef community variation across a remote, tropical island ecosystem

Katrina West, Michael Stat, Euan Harvey, Craig Skepper, Joseph DiBattista, Zoe Richards, Michael Travers, Stephen Newman & Michael Bunce
Environmental DNA (eDNA) metabarcoding, a technique for retrieving multi-species DNA from environmental samples, can detect a diverse array of marine species from filtered seawater samples. There is a growing potential to integrate eDNA alongside existing monitoring methods in order to establish or improve the assessment of species diversity. Remote island reefs are increasingly vulnerable to climate-related threats and as such there is a pressing need for efficient whole-ecosystem surveying approaches to baseline biodiversity, study assemblage...

Fortran code for modeling the propagation of ULF waves in a 3-dimensional dipole magnetosphere

Robert L Lysak, Colin Waters & Murray Sciffer
This code allows for the modeling of Ultra-Low-Frequency (ULF) waves in the Earth's magnetosphere. It has been used in a number of publications and presentations at conferences. It takes a prescribed driver in the form of a compression at the outer boundary and follows the propagation of the waves through the magnetosphere and to the ground. The output consists of files each containing snapshots of one component of the electromagnetic field at all points in...

Environmental DNA can act as a biodiversity barometer of anthropogenic pressures in coastal ecosystems

Joseph DiBattista, James Reimer, Michael Stat, Giovanni Masucci, Piera Biondi, Maarten De Brauwer, Shaun Wilkinson, Anthony Chariton & Michael Bunce
Loss of biodiversity from lower to upper trophic levels reduces overall productivity and stability of coastal ecosystems in our oceans, but rarely are these changes documented across both time and space. The characterisation of environmental DNA (eDNA) from sediment and seawater using metabarcoding offers a powerful molecular lens to observe marine biota and provides a series of ‘snapshots’ across a broad spectrum of eukaryotic organisms. Using these next-generation tools and downstream analytical innovations including machine...

Large‐scale eDNA metabarcoding survey reveals marine biogeographic break and transitions over tropical north‐western Australia

Katrina West, Michael Travers, Michael Stat, Euan Harvey, Zoe Richards, Joseph DiBattista, Stephen Newman, Alastair Harry, Craig Skepper, Matthew Heydenrych, Michael Bunce, Michael J. Travers, Euan S. Harvey, Zoe T. Richards, Joseph D. DiBattista, Stephen J. Newman & Craig L. Skepper
Aim: Environmental DNA (eDNA) metabarcoding has demonstrated its applicability as a highly sensitive biomonitoring tool across small spatial and temporal scales in marine ecosystems. However, it has rarely been tested across large spatial scales, or biogeographical barriers. Here, we scale up marine eDNA metabarcoding, test its ability to detect a major marine biogeographic break, and evaluate its use as a regional biomonitoring tool in Australia. Location: North-western Australia (NWA) Methods: We applied metabarcoding assays targeting...
