Data from: Effects of small-scale, shading-induced seagrass loss on blue carbon storage: Implications for management of degraded seagrass ecosystems

Stacey M. Trevathan-Tackett, Caitlin Wessel, Just Cebrian, Peter J. Ralph, Pere Masque & Peter I. Macreadie
1. Seagrass meadows are important global ‘blue carbon’ sinks. Despite a 30% loss of seagrasses globally during the last century, there is limited empirical research investigating the effects of disturbance and loss of seagrass on blue carbon stocks. 2. In this study, we hypothesised that seagrass loss would reduce blue carbon stocks. Using shading cloth, we simulated small-scale die-offs of two subtropical seagrass species, Halodule wrightii and Thalassia testudinum, in a dynamic northern Gulf of...

Data from: Human behaviours associated with dominance in elite bouts: a comparison of amateur boxing winners and losers under the Ten Point Must System

Emily C. Dunn, Clare E. Humberstone, K. Fiona Iredale, David T. Martin & Anthony J. Blazevich
Humans commonly ascertain physical dominance through non-lethal fighting by participating in combat sports. However, the behaviours that achieve fight dominance are not fully understood. Amateur boxing competition, which is judged using the subjective "Ten Point Must-System", provides insight into fight dominance behaviours. Notational analysis was performed on 26 elite male competitors in a national boxing championship. Behavioural (guard-drop time; movement style [stepping/bouncing time]; clinch-time; interaction-time) and technical (total punches; punches landed [Hit]; air punches [%Air];...

Data from: Managing seagrass resilience under cumulative dredging affecting light: predicting risk using dynamic Bayesian networks

Paul Pao-Yen Wu, Kathryn McMahon, Michael A. Rasheed, Gary A. Kendrick, Paul H. York, Kathryn Chartrand, M. Julian Caley & Kerrie Mengersen
Coastal development is contributing to ongoing declines of ecosystems globally. Consequently, understanding the risks posed to these systems, and how they respond to successive disturbances, is paramount for their improved management. We study the cumulative impacts of maintenance dredging on seagrass ecosystems as a canonical example. Maintenance dredging causes disturbances lasting weeks to months, often repeated at yearly intervals. We present a risk-based modelling framework for time varying complex systems centred around a dynamic Bayesian...

Data from: Ecosystem biomonitoring with eDNA: metabarcoding across the tree of life in a tropical marine environment

Michael Stat, Megan J. Huggett, Rachele Bernasconi, Joseph D. DiBattista, Tina E. Berry, Stephen J. Newman, Euan S. Harvey & Michael Bunce
Effective marine management requires comprehensive data on the status of marine biodiversity. However, efficient methods that can document biodiversity in our oceans are currently lacking. Environmental DNA (eDNA) sourced from seawater offers a new avenue for investigating the biota in marine ecosystems. Here, we investigated the potential of eDNA to inform on the breadth of biodiversity present in a tropical marine environment. Directly sequencing eDNA from seawater using a shotgun approach resulted in only 0.34%...

Data from: First circumglobal assessment of Southern Hemisphere humpback whale mitochondrial genetic variation and implications for management

Engel, Robert Baldwin, Gianna Minton, Michael Meyer, Lillian Florez-Gonzalez, M. Michael Poole, Nan Hauser, Claire Garrigue, Muriel Brasseur, John Bannister, Megan Anderson, Carlos Olavarria & C. Scott Baker
The description of genetic population structure over a species’ geographic range can provide insights into its evolutionary history and also support effective management efforts. Assessments for globally distributed species are rare, however, requiring significant international coordination and collaboration. The global distribution of demographically discrete populations for the humpback whale Megaptera novaeangliae is not fully known, hampering the definition of appropriate management units. Here, we present the first circumglobal assessment of mitochondrial genetic population structure across...

Data from: Across the Indian Ocean: a remarkable example of trans-oceanic dispersal in an austral mygalomorph spider

Sophie E. Harrison, Mark S. Harvey, Steven J.B. Cooper, Andrew D. Austin, Michael G. Rix & Steve J. B. Cooper
The Migidae are a family of austral trapdoor spiders known to show a highly restricted and disjunct distribution pattern. Here, we aim to investigate the phylogeny and historical biogeography of the group, which was previously thought to be vicariant in origin, and examine the biogeographic origins of the genus Moggridgea using a dated multi-gene phylogeny. Moggridgea specimens were sampled from southern Australia and Africa, and Bertmainus was sampled from Western Australia. Sanger sequencing methods were...
