Neutron Computed Tomography: A Novel High‐Resolution, Non‐Destructive Method for Screening Fossil Coral for Diagenetic Alteration for Geochronologic and Paleoclimatic Reconstructions Open
A novel high‐resolution, non‐destructive method for diagenetic screening of fossil corals for geochronologic and paleoclimatic studies using neutron computed tomography (NCT) is proposed. NCT circumvents limitations of traditional techniqu…

Australia’s Two Great Barrier Reefs: What Can ~360 Million Years of Change Teach Us? Open
Coral reefs are among the most important marine habitats but face significant threats from anthropogenic sources, including climate change. This paper reviews and compares the modern Great Barrier Reef Province and the 360-million-year-old…

The impact of neotectonics on the geomorphology of the northern Great Barrier Reef Open
The Great Barrier Reef (GBR) is assumed to be a tectonically stable area, but recent studies show that neotectonic activity could have affected the geomorphology and evolution of the coral reefs. We used bathymetry, free-air gravity and 2D…

Trajectories and agents of binding in stabilized and unstabilized coral rubble across environmental gradients Open
Natural ecosystems are routinely impacted by acute disturbances that generate space for early colonizers. Following disturbances, the interaction strengths of top‐down and bottom‐up factors across environmental gradients influence communit…

Subfossils suggest worse-than-realised losses of small-bodied mammals in northern Australia Open
Context Examining Australia’s late Quaternary subfossil record can be valuable in assessing whether the current diversity of small-bodied mammals seen across some parts of northern Australia is ‘normal’. Such records are important for esta…

The impact of elevated nutrients on the Holocene evolution of the Great Barrier Reef Open
The initiation of the Holocene Great Barrier Reef coincided with rapid environmental change as sea level rose and inundated the shelf. Core data from One Tree Reef (southern Great Barrier Reef) shows coral growth started by ∼8.2 ka, but ac…

Baduanjin Mind-Body Exercise for Cancer-Related Fatigue: Protocol for a Remotely Delivered Randomized Wait-List Controlled Feasibility Study Open
Background: People living with a cancer diagnosis often experience cancer-related fatigue (CRF). Between 9% and 45% of people report CRF as moderate to severe, negatively impacting their quality-of-life (QOL). The evidence-base for managin…

Mobilisation thresholds for coral rubble and consequences for windows of reef recovery Open
The proportional cover of rubble on reefs is predicted to increase as disturbances increase in intensity and frequency. Unstable rubble can kill coral recruits and impair binding processes that transform rubble into a stable substrate for …

Conservation implications of a new fossil species of hopping-mouse, <i>Notomys magnus</i> sp. nov. (Rodentia: Muridae), from the Broken River Region, northeastern Queensland Open
The Australian hopping-mouse Notomys includes 10 species, eight of which are considered extinct, vulnerable, near-threatened or endangered. Here we report a new fossil species from the Broken River Region, northeastern Queensland. Notomys …

Interim report on the vertebrate deposits recovered from the Capricorn Caves, Rockhampton, Queensland Open
Late Pleistocene to Holocene-aged microfaunal assemblages are rarely reported in Australia despite their critical importance for palaeoecological studies, as well as their bearing on the megafaunal extinction debate. Capricorn Caves, centr…

Coral rubble dynamics in the Anthropocene and implications for reef recovery Open
With rubble predicted to increase on coral reefs worldwide, we review the physical, biological, and ecological dynamics of rubble beds, with a focus on how rubble generation, mobilization, binding, and coral recruitment is expected to chan…

Micro-scale dissolution seams mobilise carbon in deep-sea limestones Open
Measuring the amount of carbon captured in deep-sea limestones is fundamental to understanding the long-term carbon cycle because pelagic limestones represent Earth’s largest carbon sink since the mid-Mesozoic. However, their contribution …

Seasonal migration of marsupial megafauna in Pleistocene Sahul (Australia–New Guinea) Open
Seasonal two-way migration is an ecological phenomenon observed in a wide range of large-bodied placental mammals, but is conspicuously absent in all modern marsupials. Most extant marsupials are typically smaller in body size in compariso…

High‐resolution hyperspectral imaging of diagenesis and clays in fossil coral reef material: a nondestructive tool for improving environmental and climate reconstructions Open
Hyperspectral imagery (1000–2500 nm) was used to quantitatively map carbonate and clay minerals in fossil reef cores that are relevant to accurately reconstructing past environmental and climatic conditions. Techniques were developed using…
