Data from: Genetic signatures through space, time and multiple disturbances in a ubiquitous brooding coralJim N. Underwood, Zoe T. Richards, Karen J. Miller, Marji L. Puotinen & James P. Gilmour
The predominance of self-recruitment in many reef-building corals has fundamental and complex consequences for their genetic diversity, population persistence and responses to climate change. Knowledge of genetic structure over local scales needs to be placed within a broad spatial context, and also integrated with genetic monitoring through time to disentangle these consequences. Here, we examined patterns of genetic diversity over multiple spatio-temporal scales across tropical Australia in the ubiquitous brooding coral, Seriatopora hystrix. We also...
Data from: Two speed invasion: assisted and intrinsic dispersal of common mynas over 150-years of colonizationKyle M. Ewart, Andrea S. Griffin, Rebecca N. Johnson, Salit Kark, Tali Magory Cohen, Nathan Lo & Richard E. Major
Aim: Despite the common myna’s widespread distribution, and the significant impact it has caused in parts of its non-native range, there have been no comprehensive genomic studies of its invasion of any region. We aimed to characterize the common myna invasion of the Australian continent to understand its population genetic landscape, introduction history, dispersal characteristics, and the interconnectedness between different source populations and invasive fronts. Location: Common mynas from 26 geographical locations spanning the Australian...
Data from: Insular biogeographic origins and high phylogenetic distinctiveness for a recently depleted lizard fauna from Christmas Island, AustraliaPaul M. Oliver, Mozes P.K. Blom, Harold G. Cogger, Robert N. Fisher, Jonathan Q. Richmond, John C.Z. Woinarski & John C. Z. Woinarski
Striking faunal turnover across Asia and Australasia, most famously along the eastern edge of the Sunda Shelf or ‘Wallace’s Line’, has been a focus of biogeographic research for over 150 years. Here we investigate the origins of a highly threatened endemic lizard fauna (4 species) on Christmas Island. Despite occurring less 350 km south of the Sunda Shelf, this fauna mostly comprises species from clades centred on the more distant regions of Wallacea, the Pacific...
Data from: Fat in the leg: function of the expanded hind leg in gasteruptiid wasps (Hymenoptera: Gasteruptiidae)István Mikó, Sarthok Rasique Rahman, Salvatore S. Anzaldo, Thomas Van De Kamp, Ben A. Parslow, Nikolai J. Tatarnic, Maxwell T. Wetherington, Julie Anderson, Rudolf J. Schilder, Jonah M. Ulmer, Andrew R. Deans & Heather M. Hines
Among some of the most unusual traits of the gasteruptiid wasps is their unique hovering flight and the expansion of their hind tibiae. Tibial expansions in female parasitoid hymenopterans often involve an enlarged sensory structure for vibration detection, the subgenual organ, thus enabling refined substrate-borne detection of concealed hosts. In the present paper, we utilize a combination of microscopy, chemical analysis, gene expression, and behavior to explore the function of the expanded hind tibia of...
Data from: Combined use of eDNA metabarcoding and video surveillance for the assessment of fish biodiversityMichael Stat, Jeffrey John, Joseph D. DiBattista, Stephen J. Newman, Michael Bunce & Euan S. Harvey
Monitoring communities of fish is important for the management and health of fisheries and marine ecosystems. Baited remote underwater video systems (BRUVs) are one of the most effective non‐destructive techniques for sampling bony fishes and elasmobranchs (sharks, rays, and skates). However, while BRUVs can sample visually conspicuous biota, some taxa are under‐sampled or not recorded at all. Here, we compared the diversity of fishes characterised using BRUVs with metabarcoding of environmental DNA (eDNA) extracted from...
Toothed cetacean (Odontoceti) lineages in the Miocene and Pliocene evolved rostra that are proportionally more elongate than any other aquatic mammal or reptile, living or extinct. Their similarities in cranial proportions to billfish may suggest a convergent feeding style, where the rostrum is swept through the water to hit and stun prey. Here we calculated second moment of area from rostral cross-sections of these fossil odontocete taxa, as well as from extant ecological analogues, to...
Data from: Short-term response of a declining woodland bird assemblage to the removal of a despotic competitorGalen Davitt, Kimberly Maute, Richard E. Major, Paul G. McDonald & Martine Maron
Interspecific aggression by the noisy miner (Manorina melanocephala), a highly despotic species, is homogenizing woodland avifaunas across eastern Australia. Although a native species, the noisy miner's aggressive exclusion of small birds is a Key Threatening Process under national law. Large‐scale removal of noisy miners has been proposed as a management response to this threat following increases in miner presence due to anthropogenic land use practices. We tested this proposal by experimentally removing noisy miners from...
Data from: A comprehensive and user-friendly framework for 3D-data visualisation in invertebrates and other organismsThomas L. Semple, Rod Peakall & Nikolai J. Tatarnic
Methods for 3D‐imaging of biological samples are experiencing unprecedented development, with tools such as X‐ray micro‐computed tomography (μCT) becoming more accessible to biologists. These techniques are inherently suited to small subjects and can simultaneously image both external and internal morphology, thus offering considerable benefits for invertebrate research. However, methods for visualising 3D‐data are trailing behind the development of tools for generating such data. Our aim in this article is to make the processing, visualisation and...
Data from: Genome-wide association study of an unusual dolphin mortality event reveals candidate genes for susceptibility and resistance to cetacean morbillivirusKimberley C. Batley, Jonathan Sandoval-Castillo, Catherine M. Kemper, Catherine R.M. Attard, Nikki Zanardo, Ikuko Tomo, Luciano B. Beheregaray & Luciana M. Möller
Infectious diseases are significant demographic and evolutionary drivers of populations, but studies about the genetic basis of disease resistance and susceptibility are scarce in wildlife populations. Cetacean morbillivirus (CeMV) is a highly contagious disease that is increasing in both geographic distribution and incidence, causing unusual mortality events (UME) and killing tens of thousands of individuals across multiple cetacean species worldwide since the late 1980’s. The largest CeMV outbreak in the Southern Hemisphere reported to date...
Effective biomonitoring is critical for driving management outcomes that ensure long-term sustainability of the marine environment. In recent years environmental DNA (eDNA), coupled with metabarcoding methodologies, has emerged as a promising tool for generating biotic surveys of marine ecosystems, including those under anthropogenic pressure. However, more empirical data is needed on how to best implement eDNA field sampling approaches to maximise their utility for each specific application. The effect of the substrate chosen for eDNA...
Ecological opportunity is a powerful driver of evolutionary diversification, and predicts rapid lineage and phenotypic diversification following colonisation of competitor-free habitats. Alternatively, topographic or environmental heterogeneity could be key to generating and sustaining diversity. We explore these hypotheses in a widespread lineage of Australian lizards: the Gehyra variegata group. This clade occurs across two biomes: the Australian monsoonal tropics (AMT), where it overlaps a separate, larger bodied clade of Gehyra and is largely restricted to...
